Wannan jagorar ya ƙunshi zaɓin tef ɗin zafin zafin jiki na PTFE don gyaran gyare-gyaren allura da aikace-aikacen rigakafin sanda. Zaɓin tushen zafin jiki: ≤260 ° C don robobi na gabaɗaya (daidaitaccen tef ɗin PSA na silicone, 0.13-0.18mm); 260-300 ° C don robobi na injiniya na zafin jiki kamar PC, PA66, POM (manufin silicone mai zafi, 0.18-0.25mm); 300-400°C don PEEK, LCP, PPS kusa da masu gudu masu zafi (tef ɗin mannewa ya gaza; yi amfani da zane na PTFE mara ɗaure ko fim ɗin PFA). Zaɓin tushen kayan abu: kayan tacky suna buƙatar babban-saki mai tsabta PTFE; Gilashin / kayan da aka cika ma'adinai suna buƙatar nauyin nauyin 0.25mm + tef mai jurewa; abubuwan da ke lalata abubuwa suna buƙatar mannen sinadarai mai juriya da maɗauri mai yawa; aikace-aikace masu ƙarfi suna buƙatar tef ɗin PTFE baƙar fata mai-tsaye.

High-tensile PTFE high-zazzabi zane da aka sanya ta shafi PTFE uwa high-ƙarfi fiberglass masana'anta, miƙa tensile ƙarfi, zafi juriya, wadanda ba sanda Properties, sinadaran juriya, da kuma low gogayya. Mahimmin aikace-aikacen sun haɗa da: isar da masana'antu (marufi na rage zafi, yin burodin abinci, bushewar yadi, bushewar takarda / fim); haɗe-haɗen gyare-gyaren kyallen saki da ɗorawa masu zafi masu zafi; walƙiya labule masu kariya da jaket ɗin zafi mai zafi; injin lantarki da rufin wuta; ginin zamiya bearings da bututun goyon bayan; tacewa sinadarai da kulle bawul a cikin mahalli masu lalata. Ƙarfin ƙarfi mai ƙarfi yana tabbatar da dorewa a ƙarƙashin tashin hankali, tsagewa, maimaita juzu'i, da matsanancin zafi na inji a cikin waɗannan aikace-aikacen nauyi daban-daban.

A lokacin sintering, PTFE barbashi a kan fiberglass masana'anta narke sama da 327 ° C, lalata asali folded sarkar lamellae da barbashi iyakoki don samar da wani amorphous narkewa. Bayan sanyaya, PTFE recrystallizes cikin spherulites kunshe da radially daidaitacce lamellae, tare da crystallinity jeri 50-70%. Kwancen kwantar da hankali yana ƙayyade ƙimar crystal: jinkirin sanyaya yana haifar da mafi girma crystallinity, mafi girma spherulites, mafi girma taurin; saurin quenching yana ba da mafi kyawun spherulites da ingantaccen sassauci.
