Umatshini we-SINOMECH wokulaminatha abathathu-kwi-nye oboniswe kumzi-mveliso weqabane lethu, udibene nezincamathelisi zokulaminatha ezingenasombululo ezivela eKangda—umvelisi ophambili we-adhesive eTshayina—unikezela ngezisombululo zokulaminatha ezinokuguquguquka neziguquguqukayo. Uxhasa ukulaminatha kwe-aluminium foil enezintlu ezintathu eziphezulu kunye nokuvuleka ngaphezulu, okubonisa indlela emfutshane yezinto ezinciphisa kakhulu umngcipheko wokuqhekeka kwe-aluminium foil. Ukongeza, uphatha ukulaminatha kwephepha-plastiki kunye neplastiki-plastiki. Xa ii-odolo zezakhiwo ezinezintlu ezintathu zinqabile, umatshini unokutshintshela kwi-lamination enezintlu ezimbini ukuze kuhlangatyezwane neemfuno ezahlukeneyo zemveliso. I-laminator yesibini yephepha-plastiki engenasombululo emithathu-kwi-nye inikezela nge-bonding yephepha-plastiki, i-strip window kunye ne-positioning window lamination, kunye nobuchule bokulaminatha bephepha eliqinileyo.
Umboniso wesicelo: I-High-Position Aluminium-Plastic Three-in-One Lamination
·Ulwakhiwo lweLamination: 12μm PET / 7μm AL / 55μm PE
·Isincamathelisi sokuLamina: I-Kangda WD8262A/B Isincamathelisi sokuLamina esingenazinyibilikisi ezibini
I-WD8262A/B, eyaphuhliswa ngokuzimeleyo yiShanghai Kangda, yiglu yokuqala yaseTshayina esebenza ngokuphezulu engenazo izinyibilikisi ezimbini enikezelwe kwi-aluminium foil lamination. Ilungiselelwe ii-composites zePET/AL eziprintiweyo ngokupheleleyo, isebenzisa itekhnoloji ye-aluminium foil lamination evuthiweyo yeKangda New Materials ukuvelisa iitemplate ezingenaziphene ezingenamabala amhlophe kwangoko emva kwe-lamination. Iifilimu ezigqityiweyo zimelana nokubulala iintsholongwane kwi-121°C imizuzu engama-40. Ukuze zihambelane neenjongo zesizwe zokunciphisa ikhabhoni kunye nokunciphisa ungcoliseko lokusingqongileyo, abavelisi abakhulu bokupakisha abaguquguqukayo kulo lonke elaseTshayina batshintsha kancinci kancinci iimveliso ze-aluminium foil eyomileyo kunye nezinye iindlela ze-lamination ezingenazo izinyibilikisi.
Amanqaku aPhambili oLawulo loBugcisa kwiNkqubo yokuLamination yePET+AL+PE enamaleko amathathu
I-PET+AL+PE sisakhiwo esidityanisiweyo esinomqobo ophezulu. I-PET inika amandla oomatshini kunye nokuprintwa; i-aluminium foil inika imisebenzi yokuthintela okuphambili kubandakanya ukuvala ukukhanya, ukumelana ne-oksijini kunye nokuthintela umphunga wamanzi; umaleko wangaphakathi we-PE uvumela ukuvalwa kobushushu kunye nokudibana ngqo nomxholo. Esi sakhiwo sisetyenziswa kakhulu ekutyeni, kwiipakethe zemihla ngemihla zeekhemikhali kunye nezamayeza. Inkqubo ye-lamination ifuna ukuchaneka okungqongqo—ulawulo olungalunganga lweenkcukacha zobugcisa luya kubangela iziphene ezifana ne-delamination, amaqamza, imibimbi, ukuqhekeka kwe-aluminium foil kunye nokuvalwa kobushushu okungalunganga. Ngezantsi kukho iinkcukacha ezibalulekileyo zolawulo lwenkqubo:
1. Unyango lwangaphambi kwe-substrate: Isiseko soMgangatho we-Lamination
Ukusebenza komphezulu wazo zonke ii-substrates kufuneka kulawulwe ngokungqongqo.
• Iifilimu zePET zifuna unyango lwe-corona ukuze zihlangabezane neemfuno zoxinzelelo lomphezulu oluqhelekileyo. Uthuli kunye nombane ongashukumiyo kumphezulu kufuneka kususwe ukuze kuthintelwe ukunamathela okungalinganiyo kunye nokwahlukana phakathi kweeleya.
• Ifoyile ye-aluminiyam ibhityile, ithambile, ithambekele ekungcolisweni kwaye igqunywe ziintsalela zeoyile eziqengqelekayo. Ukucoca nokususa amafutha kuyimfuneko, kulandele ukusebenza kwe-corona ukuze kufikelelwe kuxinzelelo lomphezulu oluyi-≥38 mN/m. Ifoyile ye-aluminiyam ene-oxidation, imingxunya okanye imifinya ayivumelekanga ngokungqongqo, njengoko ezo ziphene ziya kuphazamisa ukusebenza komqobo ngokungenakulungiswa.
• Iifilimu ze-PE zangaphakathi kufuneka zomiswe ngokupheleleyo kwaye umswakama ulawulwe ngaphantsi kwe-0.05% ukuze kuthintelwe ukuba mhlophe kunye nokudumba emva kokugquma. Iiprecipitates zomphezulu mazisuswe ukuqinisekisa ukunamathela okuzinzileyo.
2. Ulawulo loxinzelelo olulinganisiweyo ngexesha lemveliso (Eyona nto iphambili)
Umgaqo woxinzelelo oluqhubekayo owahlukileyo kufuneka usetyenziswe kwileya nganye:
• I-PET inokuqina okuphezulu; uxinzelelo lokukhulula lubekwe kwi-90–110 N ngesantya sokusebenza esingaguqukiyo nesilinganayo ukugcina imiphezulu yefilimu esithe tyaba ingenasiphazamiso.
• Ifoyile ye-aluminiyam ayinamandla okusebenza kakuhle kwaye yolula lula xa ixinezelekile. Uxinzelelo oluphantsi noluzinzileyo lwe-40–70 N luyafuneka. Ukuqalisa komatshini, ukuvala kunye nokulungiswa kwesantya kufuneka kwenziwe kancinci kancinci ukuze kuthintelwe ukuqhekeka okuncinci kunye nokuguquguquka kokuxinana okubangelwa ngamandla okutsala ngokukhawuleza.
• Iifilimu ze-PE ezithambileyo zifuna useto oluphantsi loxinzelelo ukuze kuthintelwe ukushwabana emva kokunwebeka, okukhokelela ekuqhekekeni kwemveliso egqityiweyo kunye nokwahlukana phakathi kweeleya. Uxinzelelo olujikelezayo lusebenzisa iprofayili yokunciphisa i-gradient ukuze kuthintelwe imibimbi engundoqo kunye nokutyibilika kwezinto.
3. Ukuthelekisa ngokuchanekileyo kweeParameters zokuGcoba kunye neLamination
I-lamination eyomileyo yinkqubo ekhethwayo ene-polyurethane adhesives ehambelanayo enamacandelo amabini. Ulawulo oluqinileyo lomlinganiselo wokuxuba i-adhesive kunye ne-viscosity kuqinisekisa ukusebenza kakuhle kwe-leveling.
• Ubunzima obufanayo bokugquma bugcinwa kwi-3–5 g/m². Ukungagqumi ngokwaneleyo kubangela amandla okubopha abuthathaka, ngelixa ukugquma okugqithisileyo kubangela ukuqokelelwa kweglue, ukuvala kunye nevumba elishiyekileyo.
• Ulandelelwano oluzinzileyo lwe-lamination: Bond PET nge-aluminium foil kuqala, uyinyange iiyure ezi-2-4, uze uyinyange nge-PE. I-lamination ene-multilayer ngaxeshanye iya kubangela ukunamathela okungalinganiyo.
• Ubushushu bokugalela buzinziswa kuma-60–80°C ngoxinzelelo oluphakathi nolulinganayo logalela. Ubushushu obuphantsi bukhokelela ekungaguquki kweglue; ubushushu obugqithisileyo bubangela ukuguquka kobushushu beefilimu kunye nokuqhekeka kwefoyile ye-aluminium.
4. Iinkcukacha zoNyango oluBalulekileyo kunye neNkcazelo emva kokuCwangciswa
Iimveliso ze-laminate ezigqityiweyo zidluliselwa kwigumbi lokunyanga elinobushushu obungaguqukiyo eligcinwe kwi-40–50°C kangangeeyure ezingama-24–48 ukuze kuvumeleke ukuhlanganiswa okupheleleyo kunye nokuqiniswa kwe-adhesives. Oku kuphucula kakhulu amandla okuqhekezwa kwe-interlayer kwaye kususa iingozi zokuqhekezwa kwexesha elide.
Imisebenzi yokusika nokwenza iingxowa yenziwa kuphela emva kokuba zinyangiwe ngokupheleleyo. Izinto ezibukhali eziqinileyo akufuneki ziqhagamshelane nomaleko wefoyile ye-aluminium ukuthintela umonakalo kwimingxuma ye-pinhole.
Iimveliso ezigqityiweyo mazigcinwe kwindawo eyomileyo nengangeni kukhanya, kude nobushushu obuphezulu kunye nokufuma ukuze kuthintelwe ukubola kwefoyile ye-aluminium kunye nokungaphumeleli kwe-hydrolysis ye-adhesive. Ukususwa kothuli ngokupheleleyo kuyanyanzeliswa kuyo yonke indawo yokusebenzela ukuthintela ukuvaleka kothuli phakathi kweengqimba ezifakwe i-laminated, okubangela ukuqhekeka kwamabala kunye namaqamza, ukuqinisekisa ukuba iimveliso ezigqityiweyo ziyahlangabezana nemigangatho yozinzo kunye nozinzo lwe-lamination.
