Umgangatho wokutywinwa kobushushu bengxowa yokupakisha edibeneyo ibisoloko iyenye yezona zinto zibalulekileyo kubavelisi bokupakisha ukulawula umgangatho wemveliso.Oku kulandelayo yimiba echaphazela inkqubo yokutywinwa kobushushu:
1. Uhlobo, ubukhulu kunye nomgangatho we-heat-seal-seal layer material inefuthe eliqinisekileyo kumandla okutywinwa kobushushu.Izinto ezisetyenziswa ngokuqhelekileyo zokutywinwa kobushushu ukupakishwa okuhlanganisiweyo ziquka i-CPE, i-CPP, i-EVA, i-adhesives eshushu enyibilikayo kunye nezinye i-ionic resin co-extruded okanye i-blended modified films.Ubuninzi bezinto zokufakelwa kwe-heat-sealing layer phakathi kwe-20 kunye ne-80 μm, kwaye kwiimeko ezikhethekileyo, inokufikelela kwi-100 ukuya kwi-200 μm.Kwizinto ezifanayo zokutywinwa kobushushu, amandla ayo okutywinwa kobushushu ayanda ngokunyuka kobungqimba bokutywinwa kobushushu.Amandla okutywinwa kobushushu kwebuyisela iipowutshiNgokuqhelekileyo kufuneka ukufikelela kwi-40 ~ 50N, ngoko ke ubukhulu bezinto zokutywinwa kobushushu kufuneka zibe ngaphezu kwe-60 ~ 80μm.
2. Ubushushu bokutywinwa kobushushu bunefuthe elithe ngqo kumandla okutywinwa kobushushu.Ubushushu obunyibilikayo bezinto ezahlukeneyo bumisela ngokuthe ngqo umgangatho wengxowa edibeneyo yobushushu obuncinci bokutywinwa kobushushu.Kwinkqubo yokuvelisa, ngenxa yempembelelo yoxinzelelo lokutywinwa kobushushu, isantya sokwenza ingxowa kunye nobukhulu be-substrate ehlanganisiweyo, ubushushu bokwenene bokutywinwa kobushushu buhlala buphezulu kunobushushu obunyibilikayo bezinto zokutywina ubushushu.Okukhona buncinci uxinzelelo lokutywina ubushushu, kokukhona buphakama ubushushu obufunekayo bokutywina;Isantya somatshini esikhawulezayo, kokukhona singqindilili umaleko womphezulu wefilimu ehlanganisiweyo, kwaye kokukhona uphezulu ubushushu obufunekayo bokutywinwa kobushushu.Ukuba iqondo lokushisa lokutywinwa kobushushu liphantsi kunomgangatho wokuthambisa wezinto zokutywinwa kobushushu, kungakhathaliseki indlela yokunyusa uxinzelelo okanye ukwandisa ixesha lokutywinwa kobushushu, akunakwenzeka ukwenza i-heat-seal-sealing layer.Nangona kunjalo, ukuba iqondo lokushisa lokutywinwa kobushushu liphezulu kakhulu, kulula kakhulu ukulimaza izinto zokutywinwa kobushushu kumda we-welding kunye nokunyibilika kwe-extrusion, okukhokelela kwinto ethi "ingcambu yokusika", enciphisa kakhulu amandla okutywinwa kobushushu kunye ukuchasana kwempembelelo yesikhwama.
3. Ukufezekisa amandla afanelekileyo okutywinwa kobushushu, uxinzelelo oluthile luyimfuneko.Kwiingxowa zokupakisha ezincinci kunye nezilula, uxinzelelo lokutywinwa kobushushu kufuneka lube ubuncinane ubuncinane be-2kg / cm ", kwaye luya kunyuka ngokunyuka kobunzima obupheleleyo befilimu edibeneyo. Ukufumana ukudibanisa okuyinyaniso phakathi kweefilimu ezimbini, okukhokelela kubushushu bendawo.Ukutywinwa akulunganga, okanye kunzima ukususa amaqamza omoya abanjwe embindini we weld, okukhokelela kwiwelding ebonakalayo; Kakade ke, uxinzelelo lokutywina ubushushu alukho. inkulu ngokusemandleni, akufuneki yonakalise i-welding edge, kuba kubushushu obuphezulu bokutywinwa kobushushu, Izinto zokutywina ubushushu kumphetho we-welding sele zikwimeko enyibilikisiweyo, kwaye uxinzelelo oluninzi lunokucofa ngokulula izinto zokutywina ukushisa, ukwenza umda we-welding seam wenze i-half-cut state, i-welding seam iyancipha, kwaye amandla okutywinwa kokushisa ayancipha.
4. Ixesha lokutywinwa kobushushu lichongwa ikakhulu Isantya somatshini wokwenza ingxowa sinqunywe.Ixesha lokutywinwa kobushushu liyinto ephambili echaphazela amandla okutywinwa kunye nokubonakala kwe-weld.Ubushushu obufanayo bokutywinwa kobushushu kunye noxinzelelo, ixesha lokutywinwa kobushushu lide, umaleko wokutywina ubushushu uya kuxutywa ngokupheleleyo, kwaye udibaniso luya kuba namandla, kodwa ukuba ixesha lokutywinwa kobushushu lide kakhulu, kulula ukubangela i-welding seam. ukushwabana nokuchaphazela inkangeleko.
5. Ukuba i-welding seam emva kokutywinwa kobushushu ayipholiswanga kakuhle, ayiyi kuchaphazela kuphela ukubonakala kwe-flatness ye-welding seam, kodwa ibe nefuthe elithile kumandla okutywinwa kobushushu.Inkqubo yokupholisa yinkqubo yokuphelisa uxinzelelo loxinzelelo ngokubumba i-welded seam nje emva kokunyibilika kunye nokutywinwa kobushushu kwiqondo lobushushu elisezantsi phantsi koxinzelelo oluthile.Ngoko ke, ukuba uxinzelelo alwanelanga, ukujikeleza kwamanzi okupholisa akuhambanga, umthamo wokujikeleza akwanele, ubushushu bamanzi buphezulu kakhulu, okanye ukupholisa akufike ngexesha, ukupholisa kuya kuba mbi, umgca wokutywina ubushushu uya kuba. igqwethekile, kwaye amandla okutywina ubushushu aya kuncitshiswa.
.
6. Amaxesha amaninzi okutywinwa kobushushu, kokukhona anyuka amandla okuvala ubushushu.Inani lokutywinwa kobushushu bexesha elide lixhomekeke kumlinganiselo wobude obusebenzayo bentonga ye-welding longitudinal ukuya kubude besikhwama;inani lokutywinwa kobushushu obunqamlezayo limiselwa linani leeseti zezixhobo zokutywina ubushushu ezinqamlezileyo kumatshini.Ukutywinwa kakuhle kobushushu kufuna ubuncinci amaxesha amabini okutywinwa kobushushu.Umatshini wokwenza ibhegi ngokubanzi uneseti ezimbini zeemela ezishushu, kwaye okukhona uphezulu idigri egqitheneyo yeemela ezishushu, kokukhona isiphumo sokutywinwa kobushushu singcono.
7. Kwifilimu ehlanganisiweyo yesakhiwo esifanayo kunye nobukhulu, ukuphakama kwamandla e-peel phakathi kweeleya ezidibeneyo, ubukhulu becala lokutywinwa kobushushu.Kwiimveliso ezinamandla aphantsi adibeneyo e-peel, umonakalo we-weld udla ngokuba yinto yokuqala yokuxobulwa kwefilimu edibeneyo kwi-weld, ekhokelela kumaleko angaphakathi okutywinwa kobushushu ngokuzimeleyo aphethe amandla okuqina, ngelixa umphezulu wezinto ezingaphezulu zilahlekelwa yimpembelelo yokuqinisa, kwaye ukutywinwa kobushushu be-weld Amandla ancitshiswa kakhulu.Ukuba amandla e-peel ehlanganisiweyo makhulu, i-interlayer exobuka kumda we-welding ayiyi kwenzeka, kwaye umlinganiselo wokoqobo wokutywinwa kobushushu bukhulu kakhulu.
