IiPropati eziPhambili zoMthintelo wokufuma we-TPS EVOH Resins kwi-Electronic Component Packaging
Ukukhuselwa kwezixhobo ze-elektroniki ezinovakalelo kubumanzi nakwizinto zokusingqongileyo kuhlala kungumngeni obalulekileyo kushishino lombane. I-resins ye-Ethylene Vinyl Alcohol (EVOH) ye-TPS iye yavela njengesisombululo esisisiseko sokupakishwa kwecandelo le-elektroniki, enikezela ngeempawu ezingazange zibonwe ngaphambili zokuthintela ukufuma ezandisa kakhulu ixesha lokuphila kunye nokuthembeka. Ulwakhiwo lwemolekyuli ye-EVOH, ene-ethylene etshintshwa rhoqo kunye namacandelo e-alcohol e-vinyl, yenza i-polymer ecwebezelayo enomthamo omncinci wasimahla, ikhusela ngokufanelekileyo ukungena komswakama ngelixa igcina ukucaca okubalaseleyo kunye neempawu zokusetyenzwa.
Kwizicelo zokupakisha zecandelo le-elektroniki, ii-resin ze-TPS EVOH ngokuqhelekileyo zibandakanywe njengomaleko ophakathi kwizakhiwo zokupakisha ezininzi. Olu lungelelwaniso lukhulisa iipropati zomqobo womswakama ngelixa ukhusela umaleko we-EVOH ekuvezweni ngokuthe ngqo kokusingqongileyo. Isakhiwo esiqhelekileyo siqukethe i-polyethylene yangaphandle yokukhusela i-mechanical, i-tie layer for adhesion, i-EVOH barrier layer, enye i-tie layer, kunye ne-polyethylene yangaphakathi yokutywinwa kokushisa kunye nokumelana nemichiza. Le ndlela yokwenza izinto ezininzi ibonise iziphumo ezimangalisayo, kubandakanywa iRate yokuThuthukiswa koMphunga wokufuma (MVTR) ukuya kutsho kuma-99.9% xa kuthelekiswa nemathiriyeli yokupakishwa eqhelekileyo kunye nokwandisa ubomi beshelufu kumalungu angevani nokufuma ukusuka kwiinyanga ukuya kwiminyaka.
Uphuhliso lwakutsha nje kuqulunqo lwe-EVOH lwe-TPS luqwalasele imingeni yembali efana nobuntununtunu bokufuma ngexesha lokucubungula kunye nokuqwalaselwa kweendleko. Amabakala amatsha enzelwe ngokukodwa ukupakishwa kwezicelo ze-elektroniki anika ukuchaneka okuphuculweyo kokufuma ngexesha lokucubungula ngelixa ugcina iipropathi zomqobo ezikhethekileyo. Ezi nkqubela phambili zenze i-TPS EVOH i-resins eyona nto ikhethwayo kwizinto ze-elektroniki zexabiso eliphezulu, ngakumbi kwizicelo apho ukuthembeka kwexesha elide kunye nokukhuselwa kubalulekile. Uzinzo lwe-thermal lwe-thermal luqinisekisa iipropathi zomqobo ezingaguqukiyo nasemva kokuvezwa kumaqondo obushushu okusebenza, oko kuyenza ilungele iifomathi ezahlukeneyo zokupakisha kubandakanya iingxowa, iitreyi, kunye nezicelo zokuzalisa-seal, ngelixa ukusetyenzwa kwayo okugqwesileyo kuvumela abavelisi ukuba badibanise ezi zixhobo kwimigca yokuvelisa esele ikhona. uhlengahlengiso oluncinci.
