Ta yaya PTFE da Gilashin Fiber Bond Ba tare da Delamination Ba tare da Sharuɗɗan Chemical ba?

Jiangsu Aokai New Materials, babban mai kera masana'anta na PTFE masu zafin jiki, yayi bayani:

Polytetrafluoroethylene (PTFE) da gilashin fiber (wanda aka fi sani da silica) ba zai iya samar da haɗin sinadarai ba. PTFE yana da ƙarancin makamashi mai ƙarancin ƙarfi (kimanin 18 mN/m), wanda aka sani da 'shafi mara ƙarfi', yayin da fiber gilashin abu ne na inorganic na hydrophilic polar. Biyu ba su dace ba a zahiri.

A Aokai, mu impregnate gilashin fiber zane da PTFE emulsion, yafi ta hanyar wadannan hanyoyin:Ko da yake PTFE kanta da wuya a bond, wani hada biyu wakili (kamar silane) za a iya amfani da su gina wata gada a kan gilashin fiber surface. Ka'idar ita ce: Gilashin fiber surface an mai rufi da silane hadawa wakili. Ɗaya daga cikin ƙarshen silane (kungiyar alkoxy) yana jujjuya yanayin haɓakawa tare da ƙungiyoyin silanol (Si-OH) akan fiber gilashi don samar da haɗin sinadarai; ɗayan ƙarshen (kamar rukunin amino, rukunin epoxy) yana amsawa.

Idan PTFE kanta ba a kula da shi ba, ƙarshen mai amsawa na wakili na haɗin kai ba zai iya haɗawa da PTFE ba, don haka ana buƙatar jiyya ta sama. Al'adar gama gari ita ce ƙara jami'an haɗin gwiwa da masu ɗaure polymer (kamar PFA, FEP - resin perfluoroalkoxy ko tetrafluoroethylene-hexafluoropropylene copolymer, waɗanda ke narke-mai sarrafa fluoroplastics) cikin emulsion na PTFE.

Layer canji : Perfluoroalkoxy resin ko tetrafluoroethylene-hexafluoropropylene copolymer ana amfani dashi azaman matsakaiciyar Layer. Wadannan fluoroplastics suna da kyakkyawar daidaitawar sinadarai tare da PTFE, suna iya narke da gudana a cikin ƙananan zafin jiki, haɗa fiber na gilashin silane tare da babban PTFE, samar da ƙirar gradient, da kuma kawar da maye gurbin danniya.

Haɗin kai tsakanin PTFE da fiber gilashi shine ainihin haɗin jiki na haɗin gwiwar injiniya + matsawa danniya + gradient mika mulki Layer..

Jiangsu Aokai New Materials Technology Co., Ltd ne ya samar da bayanin da ke sama.

Don cikakkun sigogi, yanayin aikace-aikacen da keɓaɓɓen mafita na kewayon samfuran mu - gami da masana'anta mai zafin jiki na PTFE, tef mai zafin jiki na PTFE, PTFE high-zazzabi raga bel, bel maras kyau don na'ura mai haɗawa, zane mai gefe guda PTFE, babban zafin jiki mai juriya mai isar da bel, babban zafin jiki mai juriya da sauran samfuran fiber: gilashin filastik mai jurewa
