Me yasa Gilashin Fiber Cloth ke Magana da Dewaxing Kafin Impregnation tare da Emulsion PTFE? Menene Ka'ida?

A matsayin ƙwararrun masana'anta na masana'anta masu zafin jiki na PTFE, Aokai New Materials yana gudanar da yanayin zafi mai zafi akan zanen fiber gilashi. Kafin impregnation tare da PTFE (Polytetrafluoroethylene) emulsion, da gilashin fiber zane sha dewaxing da dewaxing don cire sizing jamiái (textile auxiliaries) a kan fiber surface. Wadannan mataimakan suna aiki don haɗawa, lubrication da kariya yayin zana fiber da saƙa. Duk da haka, idan ba a cire su ba, za su yi mummunar illa ga ingancin haɗin PTFE da fiber gilashi. Ka'idodin sun fi kamar haka:

1. Cire Ƙananan Abubuwan Makamashi na Sama da Inganta Wettability

Paraffin, man mai da sauran abubuwan da aka gyara a cikin ma'auni masu ƙima ƙananan abubuwa ne masu ƙarfi na saman. Idan an riƙe, PTFE emulsion (tare da ƙananan tashin hankali amma tsauraran buƙatun) ba zai iya yadawa a ko'ina a kan filayen gilashin gilashi ba, wanda ke haifar da lahani irin su craters da idanu kifi. Ta hanyar tsaftacewa mai zafi mai zafi ko tsaftacewa mai ƙarfi, ana cire gurɓatattun abubuwa kuma ana ƙara yawan ƙarfin ƙarfin gilashin gilashin, yana ba da damar cikakken wetting ta PTFE.

2. Hana Carbonization da Delamination A lokacin Babban Tsananin Zazzabi

Matsakaicin zafin jiki na PTFE ya kai 360-380 ° C. Ragowar paraffin ko epoxy adhesives akan filayen fiber gilashin zai yi carbonize a irin wannan yanayin zafi mai zafi, yana samar da barbashi baki ko iskar gas. Wannan ba wai kawai ya gurɓata matsakaici ba (wanda ke shafar kaddarorin dielectric a cikin manyan laminates na jan karfe mai tsayi) amma, mafi mahimmanci, Layer carbonized yana samar da karamin karamin aiki, yana rage ƙarfin haɗin gwiwa tsakanin PTFE da fiber gilashin kuma yana haifar da delamination na kayan haɗin gwiwa.

3. Kafa Ƙarfi 'Mechanical Anchoring' Tasiri

Dewaxing mai inganci (musamman majinin zafi mai zafi) ya wuce kawai 'tsaftacewa' kawai. Yayin da aka cire kwayoyin halitta, gilashin fiber na gilashi yana dan kadan don samar da micropores ko fallasa ƙarin ƙungiyoyin silanol (-OH). Wannan yana haifar da yanayi don shafan wakili na gaba (misali, phenyl silane), ƙyale PTFE ta samar da haɗin gwiwar sinadarai ko wuraren ɗorawa ta jiki tare da fiber gilashi ta hanyar haɗakarwa jamiái - canza sauƙi 'shafi' zuwa m ' bonding '.

4. Gujewa Lalacewar Abubuwan Abubuwan Dielectric Interface

A cikin manyan aikace-aikace irin su laminates masu girma da sauri da kuma saurin jan karfe, abubuwan da suka rage na polar kwayoyin halitta (kakin zuma, danko) suna haɓaka asarar dielectric a ƙarƙashin babban zafin jiki da mita mai yawa. Dewaxing da degumming yana tabbatar da gilashin fiber-PTFE composite yana kula da ƙarancin dielectric akai-akai da asarar dielectric.

A taƙaice, ainihin maƙasudin wannan jiyya shine don kawar da yadudduka masu rauni da kuma tabbatar da cewa PTFE, ƙaramin kayan makamashi mai ƙarfi, ya sami cikakkiyar jiko da haɗin gwiwa mai ƙarfi akan tsaftataccen fiber gilashin filaye mai ƙarfi.
