Ukuvikelwa kwamahhala kwe-solvent kuvuthiwe emakethe, ikakhulukazi ngenxa yemizamo yokupakisha amabhizinisi kanye nabahlinzeki bezinto ezibonakalayo, ikakhulukazi ubuchwepheshe obuhlanzekile be-alumininam bokuphinda buziphendulile kuthathwe kabanzi, futhi uthathe isinyathelo esikhulu ngaphansi kwezimo zemvelo zokubuyisela esikhundleni se-solvent yendabuko- isisekelo isisekelo nokukhiqizwa kokukhanyiswa kwangemuva. Amabhizinisi okupakisha ahlaselwa yizinkinga ezisezingeni eliphakeme ngenxa yemibandela ehlukene yemikhiqizo emishini, ekusebenzeni, izinto zokusetshenziswa, ubuchwepheshe bekhwalithi kanye nokusetshenziswa. Leli phepha lizokhuluma ngenkinga ekhona, okungukuthi, amandla esikhwama ukuze avule futhi abushelelezi bayo.
Isibonelo, ifilimu evamile ye-polyethylene evamile eyenziwe nge-polyethylene yenziwe nge-corona ungqimba, ungqimba oluphakathi nendawo kanye nesendlalelo se-therrmal seal esiphansi. Imvamisa, ukuvula futhi okubushelelezi kwengezwa kungqimba eshisayo yokuvalwa uphawu. Izengezo ezibushelelezi zidluliswa phakathi kwezendlalelo ezi-3, kanye nokuvulwa kwezengezo akunjalo.
Njengezinto ezivuthayo zokubopha, ukuvula nezithasiselo ezibushelelezi kuyadingeka lapho ukhiqiza ama-composites aguqukayo aguqukayo. Empeleni, ahlukile, kepha abakhiqizi abaningi abapakishe abaqondi kahle ukuthi bayafana.
Isengezo esijwayelekile sokuvula i-silicon dioxide yezentengiselwano, okuyinto ye-inorganic engakhuphula ukumelana nefilimu ekuboneni. Amanye amakhasimende ahlala ethola ukuthi lezi zingqimba ezimbili zesikhwama zibonakala zinjengezibuko ezimbili ezidlula nje. Uzoqaphela ukuthi bushelelezi ukuvula nokusula, okuvame ukuntuleka ekuvuleni izengezo. Futhi ngisho nabanye abenzi befilimu abayisebenzisi.
Isengezo esibushelelezi esijwayelekile yi-ERUCIC AID Amide, okuyi-powder emhlophe evame ukunamathela ku-roller yama-lamination kanye ne-roller ye-roller kwinqubo ye-solvent-base lamingaming yenqubo. Uma ukweqiwa kwe-ejenti ebushelelezi kungezwa ngesikhathi senqubo yama-solvent-free laminianing, ezinye zizohlakazeka kuCorona ungqimba njengoba izinga lokushisa lenyuka likhuphuka, okuholela ekunciphiseni amandla. Ifilimu yasekuqaleni ye-LamiGnant PE esobala ehlutshiwe ngombala omhlophe, ingasuswa ngezicubu. Kunendlela yokuhlaziya nokuhlola ukuthi ngabe amandla ancishisiwe athintwa ukwedlula izithasiselo ezibushelelezi, ukubeka i-lighter yamandla yama-lansi isimo kuhhavini ku-80 ℃ imizuzu emihlanu, bese uvivinya amandla. Uma kukhulisa kakhulu, empeleni kuphetha ngokuthi ukuncishiswa kwamandla okukhohlisa kungenxa ye-ejenti ebushelelezi kakhulu.
Uma kuqhathaniswa nokubuyiselwa emuva kweSolvent-Base Lamination, i-solvent-free lamination indlela kulula kakhulu ukufeza ukudluliswa nokuhlakazeka. Indlela ejwayelekile yokwahlulela i-solvent free laminaming rewind ukubheka ukuthi iyinkimbinkimbi futhi icocekile ngokwanele ukuvumela ukugeleza okungcono kwesibili kwama-adhesives angenama-solvent. Ingcindezi ephakeme i-roller film ifanela, izengezo ezishelelayo kakhulu zingena elenga elihlanjululwe, noma ungqimba lokuphrinta. Ngakho-ke, sihlala sididekile ngalolu daba. Esingakwenza ukunciphisa izinga lokuphumula, kwehlise isisindo se-coating, kuthukulule ifilimu, futhi ungeze izithasiselo ezibushelelezi kaninginingi. Kepha ngaphandle kokulawulwa okuhle okungenhla, okunamathelayo kunzima ukwelapha nokubamba amanzi. Izithasiselo eziningi kakhulu ngeke zithinte kuphela amandla okhonkolo esikhwameni sepulasitiki, kepha futhi athinte ukusebenza kwawo kokushisa okushisayo.
I-Kanda New Materials ikhiphe uchungechunge lokunamathela ukuxazulula lezi zinkinga. I-WD81117A / B Ingxenye ephindwe kabili ye-solvent-free adhesive iyisincomo esihle. Kugunyazwe amaklayenti isikhathi eside.
| Ukwakheka | I-coefficient yoqobo yokuxabana | I-coeffied egayiwe yengxabano |
| Pet / pe30 | 0.1 ~ 0.15 | 0.12 ~ 0.16 |
I-WD8117A / B ingasetshenziswa ukuxazulula inkinga yamandla ampofu okukhohlisa nokusebenza kokubekwa uphawu okushisayo ngenxa yezithasiselo ezengeziwe ezibushelelezi zobuso ngaphandle kokuthola umenzi wefilimu wokuqala ukuze anciphise.
Ngokwengeziwe, i-WD8117A / B inezakhiwo ezimbili eziningi:
1. Amandla e-peiling we-OPP / Al / PE angaphezulu kuka-3.5 n, eduze noma ngaphezulu kwaleyo yezithako ezinamakhaza ezi-solvent.
2. Ukwelapha okusheshayo. Ngaphansi kwezimo eziphakanyisiwe, ifilimu ye-lamiting ingafushanisa isikhathi esingamahora ayi-8, okuphakamisa kakhulu ukusebenza kahle kokukhiqiza.
Ukufingqa, ukunqunywa kokugcina kokuphazamiseka kwe-coefficing yefilimu eyinhlanganisela kufanele kususelwe kuma-coefficients angqubuzana aphakathi phakathi kwepuleti lefilimu nensimbi. Imibono eyiphutha yokuthi kunzima ukuvula isikhwama ngoba azikho izengezo ezibushelelezi ezanele okufanele ziqashelwe futhi zilungiswe. Singakwazi ukuzuza kuphela ukuqina kanye nemikhiqizo eguquguqukayo eguquguqukayo ngokusebenzisa isifinyezo ngasinye nokuvuselelwa.
