Ayizizo zonke iifilimu ezenziwe ngokulinganayo. Oku kudala iingxaki kubo bobabini i-winder kunye nomsebenzisi. Nantsi indlela yokujongana nazo. #iingcebiso zokucubungula #ezona zenzo zilungileyo
Kwii-winders zomphezulu ophakathi, ukuxinana kwewebhu kulawulwa yi-surface drives eqhagamshelwe kwi-stacker okanye i-pinch rollers ukuze kulungiswe i-web slitting kunye nokusabalalisa iwebhu. Ukunyanzeliswa kwe-winding kulawulwa ngokuzimeleyo ukwandisa ukuqina kwekhoyili.
Xa ujija ifilimu kwi-winder ephakathi, ukuxhatshazwa kwewebhu kudalwa yi-torque ejikelezayo ye-central drive. Uxinzelelo lwewebhu luqala lusetelwe kukuqina okufunwayo kwaye emva koko kuncitshiswe njengoko ifilim iphela.

Xa ujija iimveliso zefilimu kumbindi/i-winder yobuso, i-pinch roller ishukunyiswa ukulawula uxinzelelo lwewebhu. Umzuzu wokujika awuxhomekanga kuxinzelelo lwewebhu.
Ukuba zonke iiwebhu zefilimu bezigqibelele, ukuvelisa imiqulu egqibeleleyo bekungayi kuba yingxaki enkulu. Ngelishwa, iifilimu ezigqibeleleyo azikho ngenxa yokwahluka kwendalo kwii-resin kunye ne-inhomogeneities ekubunjweni kwefilimu, iingubo kunye neendawo eziprintiweyo.
Ngaloo nto engqondweni, umsebenzi wemisebenzi yokuphefumula kukuqinisekisa ukuba ezi ziphene zingabonakali ngokubonakalayo kwaye azinyuki ngexesha lenkqubo yokucima. Umsebenzisi we-winder ke kufuneka aqinisekise ukuba inkqubo yokujija ayichaphazeli ngakumbi umgangatho wemveliso. Owona mceli mngeni kukuphelisa ifilim yokupakisha ebhetyebhetye ukuze isebenze ngaphandle komthungo kwinkqubo yemveliso yomthengi kwaye ivelise imveliso ekumgangatho ophezulu kubathengi babo.
Ukubaluleka koBungqongqo beFilimu Ukuxinana kwefilimu, okanye ukuxinana kwefilimu, yeyona nto ibalulekileyo ekuqinisekiseni ukuba ifilimu ilungile okanye imbi. Inxeba eliqengqelekayo lithambile kakhulu liya kuba “ngaphandle kwesangqa” xa linxeba, liphathwa, okanye ligcinwe. Ukujikeleza kwemiqulu kubaluleke kakhulu kumthengi ukuze akwazi ukucubungula le miqulu ngesantya esiphezulu semveliso ngelixa ugcina utshintsho oluncinci loxinzelelo.
Imiqulu eqinileyo inokubangela iingxaki ezizezazo. Banokudala iingxaki zokuthintela isiphene xa iileya zixubana okanye zincamathele. Xa ujija ifilimu eyolulayo kwi-core-walled core, ukujija umqulu oqinileyo kunokubangela ukuba undoqo uphuke. Oku kunokubangela iingxaki xa ususa i-shaft okanye ufaka i-shaft okanye i-chuck ngexesha lemisebenzi yokukhulula.
Umqulu owenziwe inxeba eliqina kakhulu unokuwenza mandundu iziphene zewebhu. Iifilimu zihlala zineendawo eziphakamileyo nezisezantsi kwindawo enqamlezayo yomatshini apho iwebhu ijiyile okanye ibhityile. Xa ujija i-dura mater, iindawo ezinobungqingqwa obukhulu ziyadibana. Xa amakhulu okanye amawaka omaleko enziwe amanxeba, amacandelo aphezulu enza ama-ridges okanye ama-projections kumqulu. Xa ifilimu isoluliwe kuzo zonke ezi ngqikelelo, iyagqwesa. Ezi ndawo ke zenza iziphene ezibizwa ngokuba "ziipokotho" kwifilimu njengoko umqulu ukhulula. Umgca womoya oqinileyo onesilayiva esishinyeneyo ecaleni kweqhina elibhityileyo lingakhokelela kwiziphene zomoya ezibizwa ngokuba ngamaza okanye amanqaku eentambo kwikroza yomoya.
Utshintsho oluncinci kwi-thickness of the wound roll aluyi kubonakala ukuba umoya owaneleyo uhlanjululwe kwi-roll kumacandelo aphantsi kwaye iwebhu ayilulwanga kumacandelo aphezulu. Nangona kunjalo, imiqulu kufuneka iboshwe ngokuqinileyo ngokwaneleyo ukuze ibe ngqukuva kwaye ihlale injalo ngexesha lokuphatha kunye nokugcinwa.
I-Randomization yokutshintsha komatshini ukuya kumatshini Ezinye iifilimu zokupakisha eziguquguqukayo, nokuba ngexesha lenkqubo yazo ye-extrusion okanye ngexesha le-coating kunye ne-lamination, zineenguqu zobunzima bomatshini ukuya kumatshini omkhulu kakhulu ukuba uchaneke ngaphandle kokugqithisa ezi ziphene. Ukulungelelanisa ukuguquguquka kwe-winder kumatshini ukuya kumatshini, i-web okanye i-slitter rewinder kunye ne-winder ihamba emva naphambili ngokumalunga newebhu njengoko iwebhu isikwa kwaye inxeba. Le ntshukumo esecaleni yomatshini ibizwa ngokuba yi-oscillation.
Ukuze i-oscillate iphumelele, isantya kufuneka sibe phezulu ngokwaneleyo ukuba sitshintshe ngokungakhethiyo ubukhulu, kwaye sisezantsi ngokwaneleyo ukuba singajiki okanye sishwabe ifilimu. Umgaqo wobhontsi wesantya esiphezulu sokungcangcazela yi-25 mm (1 intshi) ngomzuzu kwi-150 m/min nganye (500 ft/min) isantya esijikajikayo. Ngokufanelekileyo, isantya se-oscillation sitshintsha ngokuhambelana nesantya esijikelezayo.
Uhlalutyo lwe-Web Stiffness Xa umqulu wezinto zefilimu zokupakisha eziguquguqukayo zifakwe ngaphakathi kumqulu, kukho ukuxhatshazwa kumqulu okanye uxinzelelo oluseleyo. Ukuba olu xinzelelo luba lukhulu ngexesha lokujika, ukujika kwangaphakathi ukuya kumbindi kuya kuba phantsi kwemithwalo ephezulu yoxinzelelo. Yiloo nto ebangela "i-bulge" iziphene kwiindawo ezihlala kwindawo yekhoyili. Xa ujija iifilimu ezingeyo-elastic kunye nezimtyibilizi kakhulu, umaleko wangaphakathi unokukhululeka, nto leyo enokubangela ukuba umqulu ugoqe xa usonjululwe okanye usolule xa ungonakalanga. Ukuthintela oku, i-bobbin kufuneka iboshwe ngokuqinileyo kumbindi, kwaye iqine kancinci njengoko i-diameter ye-bobbin isanda.
Oku ngokuqhelekileyo kubizwa ngokuba yi-rolling hardness taper. Ubukhulu bedayamitha yebhali yenxeba egqityiweyo, kubaluleke ngakumbi iprofayili ye taper yebhali. Imfihlelo yokwenza ukuqina kokuqina kwentsimbi kukuqala ngesiseko esilungileyo esomeleleyo kwaye emva koko sigqibezele ngokunyanzeliswa okuncinci kwiikhoyili.
Ubukhulu bedayamitha yebhali yenxeba egqityiweyo, kubaluleke ngakumbi iprofayili ye taper yebhali.
Isiseko esiluqilima esilungileyo sifuna ukuba ujiko luqale ngomgangatho ophezulu, undoqo ogcinwe kakuhle. Uninzi lwezixhobo zefilimu ziboshwe kumbindi wephepha. Undoqo kufuneka womelele ngokwaneleyo ukuze umelane noxinzelelo lomoya olucinezelayo oludalwe yifilim inxeba eliqinileyo kumbindi. Ngokuqhelekileyo, i-core yephepha yomiswe kwi-oven ukuya kumswakama we-6-8%. Ukuba ezi cores zigcinwe kwindawo yokufuma okuphezulu, ziya kuthabatha oko kufuma kwaye zande ukuya kububanzi obukhulu. Emva koko, emva kokusebenza kokujikeleza, ezi ngqungquthela zinokomiswa kumxholo ophantsi womswakama kwaye zincitshiswe ngobukhulu. Xa oku kusenzeka, isiseko sokuphosa okuqinileyo kokwenzakala siya kube singasekho! Oku kunokukhokelela kwiziphene ezifana nokujika, ukugoba kunye / okanye ukuvela kwemiqulu xa iphathwa okanye ivuliwe.
Inyathelo elilandelayo ekufumaneni isiseko sekhoyili esiyimfuneko kukuqalisa ukujija ngowona bunzima buphezulu bekhoyili. Emva koko, njengoko umqulu wezinto zefilimu ulimala, ukuqina komqulu kufuneka kunciphe ngokulinganayo. Ukunciphisa okucetyiswayo kobunzima bomqulu kwidayamitha yokugqibela ngokuqhelekileyo yi-25% ukuya kwi-50% yobunzima bokuqala obulinganiswe kumbindi.
Ixabiso lokuqina komqulu wokuqala kunye nexabiso le-taper yoxinzelelo lwe-winding ngokuqhelekileyo luxhomekeke kwi-build-up ratio yomqulu wesilonda. Into yokunyuka ngumlinganiselo we-diameter yangaphandle (OD) ye-core ukuya kwi-diameter yokugqibela ye-londa roll. Okukhona usiba mkhulu idiameter yokugqibela yebhali (okukhona uphezulu ulwakhiwo), kokukhona kubaluleke ngakumbi ukuqalisa ngesiseko esilungileyo esomeleleyo kwaye ngokuthe ngcembe kuvuthelwe iibhali ezithambileyo. Itheyibhile yoku-1 inika umthetho wobhontsi weqondo elicetyiswayo lokunciphisa ubulukhuni ngokusekelwe kwinto eyongezelekayo.
Izixhobo zokujija ezisetyenziselwa ukuqinisa iwebhu zinamandla ewebhu, uxinzelelo oluphantsi (i-press okanye i-stacker rollers okanye i-winder reels), kunye ne-torque ejikelezayo ukusuka kumbindi we-drive xa ujija iiwebhu zefilimu embindini / ngaphezulu. Le migaqo-nkqubo ebizwa ngokuba yi-TNT ejikelezayo ixutyushwa kwinqaku kwi-January 2013 yePlastiki Technology. Oku kulandelayo kuchaza indlela yokusebenzisa nganye yezi zixhobo ukuyila abavavanyi bobulukhuni kwaye ibonelela ngomgaqo wesithupha wamaxabiso okuqala ukufumana abavavanyi bobunzima obufunekayo kwizinto ezahlukeneyo zokupakisha eziguquguqukayo.
Umgaqo wamandla okuguqula iwebhu. Xa ujija iifilimu ezilastiki, ukuxinana kwewebhu ngowona mgaqo uphambili wokujija osetyenziswa ukulawula ukuqina komqulu. Ukuqina kwefilimu yoluliwe ngaphambi kokuphefumula, ukuqina kwenxeba kuya kuba. Umceli mngeni kukuqinisekisa ukuba isixa soxinzelelo lwewebhu alubangeli uxinzelelo olusisigxina kwifilimu.
Njengoko kubonisiwe kwifig. I-1, xa ifilimu ejikelezayo kwi-winder ecocekileyo yeziko, ukuxhatshazwa kwewebhu kudalwa yi-torque ejikelezayo ye-center drive. Uxinzelelo lwewebhu luqala lusetelwe kukuqina okufunwayo kwaye emva koko kuncitshiswe njengoko ifilim iphela. I-web force eyenziwa yi-center drive idla ngokulawulwa kwi-loop evaliweyo kunye nempendulo evela kwi-sensor ye-tension.
Ixabiso lamandla e-blade yokuqala kunye neyokugqibela yempahla ethile idla ngokumiselwa ngokusemthethweni. Umgaqo omhle wesithupha woluhlu lwamandla ewebhu yi-10% ukuya kwi-25% yamandla okuqina kwefilimu. Amanqaku amaninzi apapashiweyo ancoma inani elithile lamandla ewebhu kwizinto ezithile zewebhu. Itheyibhile 2 idwelisa unxunguphalo olucetyisiweyo kwizinto ezininzi zewebhu ezisetyenziselwa ukupakishwa okuguquguqukayo.
Ukujija kwi-winder ecocekileyo yeziko, ukunyanzeliswa kokuqala kufuneka kube kufutshane nesiphelo esiphezulu soluhlu lwexinzelelo olucetyiswayo. Emva koko unciphise ngokuthe ngcembe ukunyanzeliswa okujikelezayo ukuya kuluhlu olucetyiswayo olusezantsi oluboniswe kule theyibhile.
Ixabiso lamandla e-blade yokuqala kunye neyokugqibela yempahla ethile idla ngokumiselwa ngokusemthethweni.
Xa ujija iwebhu elaminethiweyo yenziwe ngezinto ezininzi ezahlukeneyo, ukufumana unxunguphalo oluphezulu lwewebhu olucetyiswayo lwesakhiwo se-laminated, faka ngokulula uxinzelelo lwewebhu oluphezulu kwisixhobo ngasinye esilaminethiweyo kunye (ngokuqhelekileyo kungakhathaliseki ukuba i-coating okanye i-adhesive layer) kwaye usebenzise isimbuku esilandelayo sezi ngxabano. njengoxinzelelo olukhulu lwewebhu ye-laminate.
Umba obalulekileyo kuxinzelelo xa i-laminating flexible film compotes kukuba i-webs nganye kufuneka igxininiswe ngaphambi kokuba i-lamination ukuze i-deformation (i-elongation yewebhu ngenxa yoxinzelelo lwewebhu) iphantse ifane kwiwebhu nganye. Ukuba iwebhu enye itsalwa kakhulu kunezinye iiweb, iingxaki zokugoba okanye zokuqhawuka, ezaziwa ngokuba “yi-tunneling”, zinokubakho kwiiwebhu ezilaminethiweyo. Ubungakanani boxinzelelo kufuneka bube ngumlinganiselo wemodyuli ukuya kubukhulu bewebhu ukuthintela ukugoba kunye / okanye ukuhambisa itonela emva kwenkqubo yokuthambisa.
Umgaqo we-spiral bite. Xa ujija iifilimu ezingeyo-elastic, i-clamping kunye ne-torque yeyona migaqo iphambili yokuqina esetyenziselwa ukulawula ukuqina komqulu. I-clamp ilungisa ukuqina komqulu ngokususa umda womda womoya olandela iwebhu kwi-roller yokuthatha. I-clamp iphinda idale uxinzelelo kumqulu. Okona kuqina ibamba, kokukhona iqina i-roller ejikajikayo. Ingxaki ngefilimu yokupakisha eguquguqukayo ejikelezayo kukubonelela ngoxinzelelo olwaneleyo lokususa umoya kunye nokuvuthuza umqulu oqinileyo, othe tye ngaphandle kokwenza uxinzelelo lomoya olugqithileyo ngexesha lokujija ukuthintela umqulu ekubopheni okanye ekujikeni kwiindawo ezishinyeneyo ezikhubaza iwebhu.
Ukulayishwa kwe-Clamp kuxhomekeke kancinci kwizinto eziphathekayo kunoxinzelelo lwewebhu kwaye kunokwahluka ngokubanzi ngokuxhomekeke kwimpahla kunye nokuqina kwe-roller efunekayo. Ukuthintela ukushwabana kwefilimu yenxeba ebangelwa yi-nip, umthwalo kwi-nip ubuncinci obuyimfuneko ukukhusela umoya ukuba uvaleleke kumqulu. Lo mthwalo we-nip uhlala ungaguquguquki kwii-winders ezisembindini kuba indalo ibonelela ngamandla omthwalo we-nip rhoqo kwikhowuni yoxinzelelo kwi-nip. Njengoko i-diameter ye-roll iba nkulu, indawo yoqhagamshelwano (indawo) yesithuba phakathi kwe-roller ejikelezayo kunye ne-pressure roller iba nkulu. Ukuba ububanzi balo mzila butshintsha ukusuka kwi-6 mm (0.25 intshi) kwindawo engundoqo ukuya kwi-12 mm (0.5 intshi) kwi-roll epheleleyo, uxinzelelo lomoya luyancipha ngokuzenzekelayo ngama-50%. Ukongeza, njengoko ububanzi be-roller ejikelezayo bukhula, ubuninzi bomoya olandela umphezulu we-roller buyakhula. Lo maleko womda womoya wonyusa uxinzelelo lwehydraulic kwilinge lokuvula isithuba. Olu xinzelelo lwandisiweyo lonyusa i-taper yomthwalo wokubopha njengoko ububanzi bunyuka.
Kwii-winders ezibanzi nezikhawulezayo ezisetyenziselwa ukuvuthuza iiroli ezinkulu zedayamitha, kunokuba yimfuneko ukwandisa umthwalo kwi-clamp ejikelezayo ukuthintela umoya ukuba ungangeni kumqulu. Kwikhiwane. I-2 ibonisa i-winder yefilimu ephakathi kunye ne-air-loaded pressure roll esebenzisa i-tension kunye ne-clamping izixhobo zokulawula ukuqina kwe-wing roll.
Ngamanye amaxesha umoya ngumhlobo wethu. Ezinye iifilimu, ngokukodwa iifilimu "ezincamathelayo" ezineengxaki zokufana, zifuna i-gap winding. Ukujika komsantsa kuvumela umthamo omncinci womoya ukuba utsalelwe kwibhali ukunqanda iingxaki zokuxinga kwewebhu ngaphakathi kwebhali kwaye kunceda ukuthintela ukujika kwewebhu xa imicu engqindilili isetyenziswa. Ukuphelisa ngempumelelo ezi filimu ze-gap, umsebenzi wokuvala kufuneka ugcine isithuba esincinci, esingaguqukiyo phakathi kwe-roller yoxinzelelo kunye nezinto zokusonga. Lo msantsa omncinci, olawulwayo unceda ukulinganisa inxeba lomoya kumqulu kwaye ukhokelela iwebhu ngqo kwi-winder ukunqanda ukushwabana.
Umgaqo wokujija iTorque. Isixhobo se-torque sokufumana ukuqina komqulu ngamandla aphuhliswe embindini we-winging roll. La mandla asasazwa nge-mesh layer apho itsala okanye itsale kwi-internal wrap yefilimu. Njengoko bekutshiwo ngaphambili, le torque isetyenziselwa ukwenza amandla ewebhu kumbindi womoya. Kwezi ntlobo ze-winders, ukuxinana kwewebhu kunye ne-torque kunomgaqo ofanayo wokujikeleza.
Xa ujikelezo lweemveliso zefilimu kumbindi / umphezulu we-winder, i-pinch rollers iqhutywe ukulawula uxinzelelo lwewebhu njengoko kubonisiwe kuMzobo 3. Uxinzelelo lwewebhu olungena kwi-winder luzimeleyo kwi-tension ejikelezayo eyenziwa yile torque. Ngoxinzelelo oluqhubekayo lwewebhu olungena kwi-winder, ukuxhatshazwa kwewebhu engenayo ngokuqhelekileyo kugcinwa rhoqo.
Xa usika kunye nokubuyisela ifilimu okanye ezinye izinto ezinomlinganiselo ophezulu wePoisson, i-center / surface winding kufuneka isetyenziswe, ububanzi buya kuhluka ngokuxhomekeka kumandla ewebhu.
Xa ujija iimveliso zefilimu kumatshini ojikelezayo ophakathi / ongaphezulu, ukunyanzeliswa kwe-winding kulawulwa kwi-loop evulekileyo. Ngokuqhelekileyo, i-tension yokuqala yomoya yi-25-50% enkulu kunoxinzelelo lwewebhu engenayo. Emva koko, njengoko i-diameter yewebhu isanda, i-winding tension iyancipha ngokuthe ngcembe, ifikelele okanye ingaphantsi koxinzelelo lwewebhu engenayo. Xa ukunyanzeliswa kwe-winding kukhulu kunoxinzelelo lwewebhu olungenayo, i-roller surface drive drive ihlaziya okanye ivelise i-torque engalunganga (i-braking). Njengoko ububanzi be-winding roller bunyuka, i-drive drive iya kunika i-braking encinci nangaphantsi kuze kube yilapho i-torque ye-zero ifikeleleke; emva koko ukunyanzeliswa kwe-winding kuya kufana ne-web tension. Ukuba ukuxinana komoya kucwangciswe ngezantsi kwamandla ewebhu, idrayivu ephantsi iya kutsala itorque evumayo ukubuyisela umahluko phakathi koxinzelelo lomoya olusezantsi kunye namandla ewebhu aphezulu.
Xa usika kunye nefilimu ejikelezayo okanye ezinye izinto ezinomlinganiselo ophezulu wePoisson, kufuneka kusetyenziswe iziko / ukujikeleza kwendawo, kwaye ububanzi buya kutshintsha ngamandla ewebhu. Umbindi wee-winders zomphezulu zigcina ububanzi obuqengqelekayo obuqengqelekayo ngenxa yokuba unxunguphalo lwewebhu oluqhubekayo lusetyenziswa kwi-winder. Ubunzima bomqulu buya kuhlalutywa ngokusekelwe kwi-torque kwiziko ngaphandle kweengxaki kunye nobubanzi be-taper.
Impembelelo yefilimu yefriction factor ekujikeni Ifilimu ye-interlaminar coefficient of friction (COF) iipropati zinempembelelo enkulu ekukwazi ukusebenzisa umgaqo we-TNT ukufumana ukuqina komqulu ofunekayo ngaphandle kweziphene. Ngokuqhelekileyo, iifilimu ezine-coefficient ye-interlaminar friction ye-0.2-0.7 iqengqeleka kakuhle. Nangona kunjalo, imiqulu yefilim engenasiphene eqengqelekayo kunye nokutyibilika okuphezulu okanye okuphantsi (i-coefficient ephantsi okanye ephezulu yokukhuhlana) ihlala inikezela ngeengxaki ezibalulekileyo.
Iifilimu eziphezulu ze-slip zine-coefficient ephantsi ye-interlaminar friction (ngokuqhelekileyo ingaphantsi kwe-0.2). Ezi bhanyabhanya zihlala zihlupheka ngenxa yokutyibilika kwewebhu kwangaphakathi okanye iingxaki ezijikajikayo ngexesha lokujija kunye/okanye imisebenzi yokungaphumli, okanye iingxaki zokuphatha iwebhu phakathi kwale misebenzi. Oku kutyibilika kwangaphakathi kwencakuba kunokubangela iziphene ezinje ngokukrweleka kweencakuba, izibonda, iteleskopu kunye/okanye iziphene zokuqengqeleka kweenkwenkwezi. Iifilimu ze-friction eziphantsi kufuneka ziboshwe ngokungqongqo ngokusemandleni kwi-torque ephezulu. Emva koko ukunyanzeliswa kwe-winging eveliswa ngulo torque kuncitshiswa ngokuthe ngcembe ukuya kwixabiso elincinci lamaxesha amathathu ukuya kwamane ububanzi obungaphandle be-core, kunye nokuqina komqulu ofunekayo kuphunyezwa ngokusebenzisa umgaqo wokugoqa. Umoya awusoze ube ngumhlobo wethu xa kufikwa kwifilimu etyibilikayo. Ezi bhanyabhanya kufuneka zisoloko zingxwelerheka ngamandla awoneleyo okubamba ukuthintela umoya ukuba ungangeni kumqulu ngexesha lokujikajika.
Ifilimu ye-slip ephantsi ine-coefficient ephezulu ye-interlaminar friction (ngokuqhelekileyo ngaphezu kwe-0.7). Ezi filim zihlala zinengxaki yokuthintela kunye / okanye imibimbi. Xa iifilimu ezijikelezayo ezine-coefficient ephezulu ye-friction, i-ovality eqengqelekayo kwizantya ezisezantsi ezijikajikayo kunye neengxaki zokubhobhoza kwizantya ezivuthuzayo zinokwenzeka. Le miqulu isenokuba ineziphene eziphakanyisiweyo okanye ezinamaza ezaziwa ngokuba ngamaqhina atyibilikayo okanye imibimbi yokutyibilika. Iifilimu eziphezulu zokukhuhlana zingcono kakhulu inxeba kunye nomsantsa onciphisa umsantsa phakathi kokulandelayo kunye nemiqulu yokuthatha. Ukusasaza kufuneka kuqinisekiswe ngokusondeleyo kangangoko kunokwenzeka kwindawo yokusonga. I-FlexSpreader idyasa iiroli ze-idler ezinenxeba phambi kokujija kwaye inceda ukunciphisa iziphene zokutyibilika xa ujija ngokungqubana okuphezulu.
