Ikhwalithi yokuvala ukushisa kwezikhwama zokupakisha eziyinhlanganisela ibilokhu ingenye yezinto ezibaluleke kakhulu kubakhiqizi bokupakisha ukuze balawule ikhwalithi yomkhiqizo.Okulandelayo yizici ezithinta inqubo yokuvala ukushisa:
1. Uhlobo, ukujiya kanye nekhwalithi yongqimba oluvala ukushisa kunomthelela omkhulu emandleni okuvala ukushisa.Izinto ezisetshenziswa ngokujwayelekile zokuvala ukushisa zokupakisha okuyinhlanganisela zifaka i-CPE, i-CPP, i-EVA, izinamatheliso ezincibilikayo ezishisayo namanye amafilimu e-ionic resin ahlanganisiwe noma ahlanganisiwe ahlanganisiwe.Ubukhulu bezinto zongqimba ezivala ukushisa ngokuvamile ziphakathi kuka-20 no-80 μm, futhi ezimweni ezikhethekile, zingafinyelela ku-100 kuya ku-200 μm.Ngempahla efanayo yokuvala ukushisa, amandla ayo okuvala ukushisa ayanda ngokukhula kokuqina kokuvalwa kokushisa.Amandla okuvalwa kokushisa kwe-buyisela izikhwamangokuvamile kuyadingeka ukuze kufinyelelwe ku-40 ~ 50N, ngakho-ke ubukhulu bempahla yokuvala ukushisa kufanele ibe ngaphezu kuka-60~80μm.
2. Izinga lokushisa lokuvalwa kokushisa linethonya eliqondile kakhulu emandleni okuvalwa kokushisa.Izinga lokushisa elincibilikayo lezinto ezihlukahlukene linquma ngokuqondile ikhwalithi yesikhwama esiyinhlanganisela izinga lokushisa elincane lokuvalwa kokushisa.Enqubweni yokukhiqiza, ngenxa yethonya lokucindezela kokuvalwa kokushisa, isivinini sokwenza isikhwama kanye nobukhulu be-substrate eyinhlanganisela, izinga lokushisa langempela lokuvalwa kokushisa livame ukuba ngaphezu kwezinga lokushisa elincibilikayo lempahla yokuvala ukushisa.Lapho ingcindezi yokuvala ukushisa incane, izinga lokushisa elidingekayo lokuvala uphawu liyakhuphuka;lapho isivinini somshini sishesha, kushuba ungqimba olungaphezulu lwefilimu eyinhlanganisela, futhi kukhushulwe izinga lokushisa elidingekayo lokuvalwa kokushisa.Uma izinga lokushisa lokuvalwa kokushisa liphansi kunephuzu lokuthambisa lempahla yokuvala ukushisa, kungakhathaliseki ukuthi ukwandisa kanjani ukucindezela noma ukwelula isikhathi sokuvala ukushisa, akunakwenzeka ukwenza ungqimba lokuvala ukushisa luvalwe ngempela.Kodwa-ke, uma izinga lokushisa lokuvalwa kokushisa liphezulu kakhulu, kulula kakhulu ukulimaza impahla yokuvala ukushisa onqenqemeni lwe-welding kanye nokuncibilika kwe-extrusion, okuholela esimweni "sokusika izimpande", okunciphisa kakhulu amandla okuvalwa kokushisa kophawu futhi ukumelana komthelela wesikhwama.
3. Ukuze kuzuzwe amandla afanelekile okuvalwa kokushisa, ingcindezi ethile ibalulekile.Ezikhwameni zokupakisha ezincane nezilula, ingcindezi yokuvala ukushisa kumele okungenani ibe ngu-2kg/cm", futhi izokhula ngokunyuka kobukhulu obuphelele befilimu ehlanganisiwe. Uma ukucindezela kokuvalwa kokushisa kunganele, kunzima ukufeza ukuhlanganiswa kweqiniso phakathi kwamafilimu amabili, okuholela ekushiseni kwendawo akukuhle, noma kunzima ukususa ama-bubbles omoya abanjwe phakathi kwe-weld, okuholela ekushiseni okubonakalayo, ingcindezi yokuvala ukushisa ayikho inkulu ngangokunokwenzeka, akufanele ilimaze onqenqemeni lwe-welding, ngoba ekushiseni okuphezulu kokuvalwa kokushisa, Impahla yokuvala ukushisa onqenqemeni lwe-welding isivele isesimweni esincibilikisiwe, futhi ukucindezela okukhulu kungakhama kalula ingxenye ye-welding. impahla yokushisa ukushisa, okwenza unqenqema lwe-welding seam lube yi-half-cut state, i-welding seam i-brittle, futhi amandla okuvala ukushisa ayancipha.
4. Isikhathi sokufaka uphawu lokushisa ngokuyinhloko sinqunywa Isivinini somshini wokwenza isikhwama sinqunywa.Isikhathi sokuvala ukushisa siphinde sibe yisici esibalulekile esithinta amandla okuvala nokubukeka kwe-weld.Ukushisa okufanayo kokuvalwa kokushisa nokucindezela, isikhathi sokuvalwa kokushisa side, isendlalelo sokuvala ukushisa sizohlanganiswa ngokugcwele, futhi inhlanganisela izoba namandla, kodwa Uma isikhathi sokuvala ukushisa siside kakhulu, kulula ukubangela i-welding seam. ukushwabana futhi kuthinte ukubukeka.
5. Uma i-welding seam ngemuva kokuvalwa kokushisa ingapholi kahle, ngeke nje ithinte ukubukeka kwe-welding seam, kodwa futhi ibe nomthelela othile emandleni okufaka uphawu okushisa.Inqubo yokupholisa iyinqubo yokuqeda ukugxiliswa kwengcindezi ngokubumba umthungo oshiselwe ngemva nje kokuncibilika nokuvala ukushisa endaweni ephansi yokushisa ngaphansi kwengcindezi ethile.Ngakho-ke, uma ingcindezi inganele, ukujikeleza kwamanzi okupholisa akubushelelezi, umthamo wokujikeleza akwanele, izinga lokushisa lamanzi liphezulu kakhulu, noma ukupholisa kungenasikhathi, ukupholisa kuzoba mpofu, umkhawulo wokuvala ukushisa uzoba esontekile, futhi amandla okuvala ukushisa azoncipha.

6. Izikhathi eziningi zokuvalwa kokushisa, kuyanda amandla okuvala ukushisa.Inombolo yokuvalwa kokushisa kwe-longitudinal incike esilinganisweni sobude obusebenzayo benduku ye-welding longitudinal kuya kubude besikhwama;inombolo yokuvalwa kokushisa okuphambene inqunywa inani lamasethi emishini yokuvala ukushisa okuphambene emshinini.Ukuvala ukushisa okuhle kudinga okungenani izikhathi ezimbili zokuvalwa kokushisa.Umshini ojwayelekile wokwenza izikhwama unamasethi amabili emimese eshisayo, futhi uma uphakeme izinga eligqagqene lemimese eshisayo, kuba ngcono umphumela wokuvala ukushisa.
7. Ngefilimu eyinhlanganisela yesakhiwo nokuqina okufanayo, lapho amandla ekhasi aphakeme phakathi kwezingqimba eziyinhlanganisela, ayanda amandla okuvala ukushisa.Emikhiqizweni enamandla aphansi e-peel eyinhlanganisela, ukulimala kwe-weld kuvame ukuxebuka kwe-interlayer yokuqala yefilimu eyinhlanganisela endaweni yokushisela, okuholela ekutheni ungqimba oluvala ukushisa lwangaphakathi lube namandla aqinile, kuyilapho ungqimba olungaphezulu lulahlekelwa umphumela walo wokuqiniswa, futhi i-heat-sealing of the weld Amandla ancipha kakhulu.Uma amandla e-peel ehlanganisiwe emakhulu, ukuxebuka kwe-interlayer onqenqemeni lwe-welding ngeke kwenzeke, futhi amandla ophawu lokushisa alinganisiwe makhulu kakhulu.
