Umphumo wetonela ubhekiselele ekubunjweni kweeprotrusions ezingenanto kunye nemibimbi kwelinye umaleko we-substrate ethe tyaba, kwaye kwelinye umaleko we-substrate ephumayo ukuze yenze iiprotrusions ezingenanto kunye nemibimbi.Idla ngokubaleka ngokuthe tye kwaye iqhele ukubonwa kwiziphelo ezimbini zegubu.Kukho izinto ezininzi ezinokubangela umphumo wetonela.Ngezantsi, siza kubonelela ngentshayelelo eneenkcukacha.
Izizathu ezisixhenxe zokusabela kwitonelaUmdibanisoifilimu
1.Uxinzelelo ngexesha le-composite aluhambelani. Emva kokuba i-composite igqityiwe, i-membrane egxininiswe ngaphambili iya kuthotywa, ngelixa enye i-maleko ene-tension ephantsi iya kuthotywa ngaphantsi okanye ingabikho, ibangele ukufuduka kunye nokuvelisa imibimbi ephakanyisiweyo.Xa uncamathelisa i-adhesive kwiifilim ezinokwelula ngokulula kunye nokudityaniswa neefilim ezinganwebekayo, iziphumo zetonela zidla ngokubakho.Ngokomzekelo, kukho ifilimu edibeneyo ene-BOPP / AI / PE isakhiwo se-three-layer structure.
Xa umaleko wokuqala we-BOPP udibaniswa ne-AI, i-BOPP yokugqoka ingena kwi-tunnel yokumisa ukufudumeza kunye nokomisa.Ukuba ukunyanzeliswa kwe-unwinding kuphezulu kakhulu, kudityaniswa nokufudumeza ngaphakathi kwitonela yokomisa, i-BOPP yoluliwe, kwaye ukunyuswa komgangatho we-AI kuncinci kakhulu.Emva kokudibanisa, i-BOPP iyancipha, ibangela ukuba i-AI ikhuphe kwaye yenze i-tunnel transverse.Ngexesha le-composite yesibini, i-(BOPP / AI) layer isebenza njenge-coating substrate.Ngenxa yoluhlu lwe-AI, ulwandiso lwefilimu luncinci kakhulu.Ukuba i-tension yefilimu ye-PE yesibini evulekileyo iphezulu kakhulu, ifilimu ye-PE ilula kwaye ikhubazekile.
Emva kokuba i-composite igqityiwe, i-PE iyancipha, ibangela ukuba (BOPP / AI) umaleko uqhube kwaye wenze i-tunnel.Ngoko ke, kuyimfuneko ukuhambelana noxinzelelo ngokweempawu zezixhobo ezahlukeneyo.
2.Ifilimu ngokwayo ishwabene, ayilingani ngobukhulu, kwaye inamaphethelo avulekileyo. Ukuqulunqa olu hlobo lwefilimu, kuyimfuneko ukunciphisa isantya sokudibanisa kunye nokunyusa ukunyanzeliswa kokunciphisa.Nangona kunjalo, emva kwexesha elithile, i-tunnel phenomenon iya kwenzeka, ngoko i-flatness ye-substrate yefilimu ibaluleke kakhulu.
3.Ukuvuthwa okungafanelekanga kufuna ukulungelelanisa uxinzelelo olujikelezayo ngokwesakhiwo sefilimu #edibeneyo. Yandisa i-taper yefilimu enzima kunye nenzima, kwaye ungabangeli ukukhululeka kwangaphakathi kunye nokuqina kwangaphandle, okukhokelela kwisiganeko setonela kwimibimbi.Ngaphambi kokudibanisa, ifilimu kufuneka ipholile ngokupheleleyo.Ukuba i-coiling ikhululekile kakhulu, kukho ukukhululeka, kwaye kukho umoya omkhulu phakathi kweengqungquthela zefilimu, ezingahambelani ngokufanelekileyo, i-tunnel phenomenon nayo ingenzeka.
4.I-adhesive inobunzima obuncinci bemolekyuli, ukudibanisa okuphantsi, kunye nokunamathela okuphantsi kokuqala, engakwazi ukuthintela ukutyibilika kwefilimu kwaye ibangele i-tunnel phenomenon.Ngoko ke, i-adhesive efanelekileyo kufuneka ikhethwe.
5.Isixa esingafanelekanga seglue esisetyenzisiweyo. Ukuba ubungakanani be-adhesive esetyenzisiweyo ayinelanga okanye ayilingani, ibangela ukungonelanga okanye ukungalingani kwamandla okudibanisa, okubangelwa iimeko zetonela kwiindawo zendawo.Ukuba i-adhesive isetyenziswe kakhulu, ukunyanga kucotha, kwaye ukutyibilika kwenzeka kwi-adhesive layer, kunokubangela ukuba i-tunnel phenomenon.
6.Umlinganiselo ongafanelekanga wokuncamathelisa, umgangatho ombi wokunyibilikisa, kunye nokufuma okuphezulu okanye isiqulatho sotywala kunokubangela ukucotha kokunyanga kunye nokutyibilika kwefilimu. Ngoko ke, kuyimfuneko ukuvavanya rhoqo i-solvent kunye nokuvuthwa ngokupheleleyo ifilimu edibeneyo.
7. Kukho ii-solvents ezininzi eziseleyo kwifilimu edibeneyo, i-adhesive ayimile ngokwaneleyo, kwaye amandla okudibanisa ancinci kakhulu. Ukuba i-tension ayihambelani ngokufanelekileyo, kulula ukubangela ukutyibilika kwefilimu.
Oku kungasentla kukudityaniswa kunye nokwabelana ngoncwadi olukwi-intanethi, ukuba uneemfuno zokuthengwa kwefilimu yeComposite, nceda uqhagamshelane nathi:
