Iipropati zoMqobo woMfutho oPhambili we-TPS EVOH Resins kwiPakethe yeCandelo le-elektroniki
Ukukhuselwa kwezinto ze-elektroniki ezinobuthathaka kumswakama nakwizinto ezisingqongileyo kusengumngeni obalulekileyo kushishino lwe-elektroniki. Utywala be-Ethylene Vinyl Iiresini (EVOH) ziye zavela njengesisombululo esiphambili sokupakisha izinto ze-elektroniki ezikhethekileyo, zibonelela ngeempawu zokuthintela umswakama ezingazange zibonwe ngaphambili ezandisa ubomi bezinto kunye nokuthembeka kwazo. Ulwakhiwo lwemolekyuli ye-EVOH, oluneziqendu ze-ethylene kunye ne-vinyl alcohol ezitshintshana rhoqo, ludala i-polymer ekristale kakhulu enomthamo omncinci wasimahla, ithintela ngempumelelo ukungena komswakama ngelixa igcina ukucaca okugqwesileyo kokukhanya kunye neempawu zokucubungula.
Kwizicelo zokupakisha izinto ze-elektroniki, i-TPS I-Evoh ResinIi-s zihlala zifakwa njengomaleko ophakathi kwizakhiwo zokupakisha ezineengqimba ezininzi. Olu lwakhiwo lukhulisa iipropati zokuthintela ukufuma ngelixa lukhusela umaleko we-EVOH ekuchatshazelweni ngqo kokusingqongileyo. Ulwakhiwo oluqhelekileyo luqulathe umaleko we-polyethylene wangaphandle wokukhusela oomatshini, umaleko weqhina lokunamathela, umaleko weqhina le-EVOH, omnye umaleko weqhina, kunye nomaleko we-polyethylene wangaphakathi wokuvala ubushushu kunye nokumelana neekhemikhali. Le ndlela ye-multilayer ibonise iziphumo ezimangalisayo, kubandakanya ukwehla kwe-Moisture Vapor Transmission Rate (MVTR) ukuya kuthi ga kwi-99.9% xa kuthelekiswa nezixhobo zokupakisha eziqhelekileyo kunye nobomi obude beshelufu bezinto ezinobuthathaka kumswakama ukusuka kwiinyanga ukuya kwiminyaka.
Uphuhliso lwakutshanje kwiifomyula ze-EVOH ze-TPS lujongane nemingeni yembali efana nobuthathaka bokufuma ngexesha lokucubungula kunye nokuqwalaselwa kweendleko. Amanqanaba amatsha aklanyelwe ngokukodwa usetyenziso lokupakisha nge-elektroniki anika ukumelana nokufuma okuphuculweyo ngexesha lokucubungula ngelixa egcina iipropati zokuthintela ezibalaseleyo. Olu phuculo lwenze ii-resin ze-TPS EVOH zibe lukhetho olukhethwayo lwezinto ze-elektroniki ezixabisa kakhulu, ngakumbi kwizicelo apho ukuthembeka nokukhuselwa kwexesha elide kubalulekile. Uzinzo lobushushu bezinto ezisetyenzisiweyo luqinisekisa iipropati zokuthintela ezihambelanayo nokuba sele zichatshazelwe kubushushu bokucubungula, nto leyo eyenza ukuba ifaneleke kwiifomathi ezahlukeneyo zokupakisha kubandakanya iingxowa, iitreyi, kunye nezicelo zokugcwalisa ifomu, ngelixa ukuqhubekeka kwayo okuhle kuvumela abavelisi ukuba badibanise ezi zinto kwimigca yemveliso ekhoyo ngotshintsho oluncinci.
