Surface karewa jamiái shafi fiberglass masana'anta kafin PTFE shafi ne m ga karshe PTFE high-zazzabi zane yi. Ma'aikatan haɗin gwiwar Organosilane suna haifar da gadoji na kwayoyin halitta tsakanin fiber gilashin inorganic da PTFE na kwayoyin halitta, suna ƙarfafa ƙarfin kwasfa daga <2 N/cm zuwa 4-8+ N/cm. Hakanan magani mai kyau yana haɓaka juriya na zafi (260°C+), aikin dielectric, da juriya na sinadarai. Yaduwar da ba a kula da ita tana kaiwa ga lalatawa, kumfa, da gajeriyar rayuwar sabis.

Warp da weft yawa na fiberglass masana'anta yana ƙayyade aikin zane mai zafin jiki na PTFE. Maɗaukakin girma yana ƙara ƙarfin juriya da santsin saman amma yana rage ƙarfin hawaye (inverted U-curve), sassauci, da shigar da shafi. Mafi kyawun ma'auni mai yawa yana daidaita shiga, juriya, sassauci, da gamawa. Ƙananan yawa sun dace da lanƙwasawa mai ƙarfi; babban yawa don rashin sanda da rufi.

Matsakaicin PTFE a zahiri yana da juriya na feshi gishiri (shar ruwa <0.01%). Koyaya, aikin tef ɗin gabaɗaya ya dogara da nau'in mannewa: silicone PSA yana jure yanayin yanayin ruwa (gwajin feshin gishiri 500-1000h,> 80% riƙe kwasfa); acrylic PSA ya kasa. Maganin saman da ya dace, aikace-aikacen kumfa, da rufe baki tare da silin siliki suna da mahimmanci don dogaro na dogon lokaci akan dandamali da tasoshin ruwa.

Calendering - latsa PTFE-rufi masana'anta tsakanin zafi madubi rollers a 360-380 ° C - cika fuska canza surface ilimin halittar jiki, saki kaddarorin, impermeability, da inji yi. Yana rage rashin ƙarfi daga Ra 0.5-1.0 μm zuwa <0.05 μm, yana rufe raƙuman ruwa, yana inganta juriya, amma yana rage ƙarfin hawaye da sassauci. Mahimmanci don sakin layi na lantarki da rufin lantarki.

Tsarin saƙa na fiberglass - bayyananne, twill, ko satin - yana tasiri sosai ga masana'anta masu zafin jiki na PTFE. Sakin Satin yana ba da mafi girman ƙarfin hawaye (2-3x a fili) da sassauci, manufa don lankwasawa mai ƙarfi. Saƙa na fili yana ba da mafi kyawun kwanciyar hankali da mannewa bawo, wanda ya dace da aikace-aikacen a tsaye. Twill yana daidaita duk kaddarorin don amfanin gaba ɗaya.

Tef ɗin fiberglass na PTFE yana buƙatar takaddun shaida na aminci guda uku: UL (lantarki da lafiyar harshen wuta), FDA (cirewar hulɗar abinci), da ISO 9001: 2015 (Gudanar da inganci). Taffofin ƙwararrun kaset suna ba da daidaiton aiki, rayuwar sabis mai tsayi, da ƙarancin ƙimar ikon mallaka duk da ƙarin farashi na gaba. Koyaushe tabbatar da takaddun shaida kai tsaye tare da ƙungiyoyi masu bayarwa.

PTFE conveyor belts (Teflon belts) inganta abinci sarrafa Lines ta hudu key amfanin: m maras sanda yi (rage sharar gida da mai danko), fadi da zafin jiki haƙuri (-100 ° C zuwa 260 ° C sa yin burodi zuwa daskarewa), sauki tsaftacewa da kwayan juriya (ba porous surface, FDA yarda), da kuma aiki tanadi (ƙananan makamashi amfani, bel tsawon rayuwa). Ya dace da kayan gasa, abinci daskararre, cakulan, da samfuran m.

PTFE high-zazzabi tef ake amfani a fadin uku likita aikace-aikace tiers: haifuwa kayan aiki kariya (autoclave trays, zafi-hatimin marufi), kayan aiki surface jiyya (ƙananan gogayya shafi, lantarki rufi), da implantable na'urorin (vascular grafts, sutures). An tabbatar da daidaituwar halittu ta hanyar ISO 10993, kuma FDA 21 CFR 177.1550 ta kafa amincin kayan aiki.

Rufi uniformity na PTFE high-zazzabi masana'anta ne m da hudu dalilai: shafi halitta (barbashi size 0.15-0.35 μm, danko, m abun ciki), shafi & sintering tsari ( ruwa shafi fĩfĩta ga uniformity), substrate quality (saƙa juna, pre-jiyya), da kuma samar da yanayi (20-25 ° C, <60% RH). Dip + ruwan ruwa hade tsari yana daidaita ma'aunin shigar ciki da santsin saman.

PTFE surface jiyya ga bonding manne yana amfani da manyan hanyoyi guda biyu: high-zazzabi narkewa (mafi girma weather juriya, 9.5 MPa ƙarfi tare da hada guda biyu wakili, amma saki mai guba gas) da sodium-naphthalene etching (5 MPa nan da nan adhesion, kunkuntar 24-48 hour taga, m sharar gida).
