High-ƙarfi PTFE high-zazzabi masana'anta ne a hada da high-tenacity fiberglass da PTFE shafi. Key aikace-aikace span masana'antu isar (abinci yin burodi, yadi bushewa, PCB sufuri), walda kariya (zafi-sealer cover, spatter garkuwa), rushewa da zafi latsa forming (rubber gyare-gyare, PV lamination), lantarki rufi (motor Ramin liners, na USB wraps), architectural membranes (filin rufi rufi, 30+ shekara rayuwa), sinadarai anti-corro, sinadarai anti-corro. barguna), da aikace-aikace na musamman (yankewar Laser, bugu 3D).

Bushewa mataki ne mai mahimmanci a cikin samar da masana'anta mai zafin jiki na PTFE. Lalacewar yau da kullun sun haɗa da: fatattaka ( bushewa da sauri, fatar jiki), ƙaura mai shafa (barbashi suna motsawa zuwa saman, raunin ciki mai rauni), ɗigon ruwa / blisters (iska mai kama da iska ko tururi), ɗigon fari da chalking ( ƙaurawar surfactant ko haɗuwa da bai cika ba), yellowing/coking (zazzaɓi na ƙari), delamination (kanƙuncewar damuwa ya wuce mannewa), matakin bushewa na lemu rigar ciki (fatar tarkon danshi), da kauri gefuna (sakamakon zoben kofi). Magani sun haɗa da bayanan bayanan bushewa mai sarrafawa, samun iska mai kyau, da pretreatment na ƙasa.

PTFE emulsion impregnation na fiberglass masana'anta na bukatar daban-daban auxiliaries cimma uniform shafi, karfi mannewa, da lahani-free saman. Key additives sun hada da: wetting jamiái (rage surface tashin hankali, inganta shigar azzakari cikin farji), thickeners (control danko da shafi nauyi), pH regulators (stabilize emulsion a pH 9-10), silane hada guda biyu jamiái (haɓaka mannewa zuwa gilashin), film-forming AIDS (PFA / FEP ga sintering), functional filler (mafi preventive), aiki fillers (wear) humectants (jinkirin bushewa). Zaɓin ya dogara da ƙa'idar aiki da buƙatun aiki.

Faɗaɗɗen masana'anta na fiberglass (ƙarancin yarn yarn) ya bambanta da gaske daga masana'anta fiberglass na al'ada a cikin tsarin yarn. Ta hanyar maganin jet mai matsananciyar iska, ana raba filayen gilashin ci gaba, an gurɓace, kuma a juye su cikin ƙaranci, yarn mai kama da auduga. Wannan yana haifar da kauri, masana'anta mai laushi tare da mafi girman rufin thermal (sarkin iska mai kama da tarko), ingantacciyar daidaituwa, ingantaccen tacewa, da ingantaccen juriya / juriya - a farashin ɗan ƙaramin ƙarfi mai ƙarfi. Ana amfani da shi don gaskets masu zafin jiki, bututun bututu, jakunkuna masu tacewa, da hatimin tanda.

Raw kayan tsabta shine tushen PTFE high-zazzabi masana'anta yi. High-tsarki PTFE emulsion (babu ions karfe, babu ragowar ƙananan nauyin kwayoyin halitta) yana tabbatar da juriya na zafi (babu rawaya har zuwa 260 ° C), barga maras sanda, da ƙarfin ƙarfin lantarki. Don gilashin fiberglass, gilashin E-glass maras alkali (Na₂O <0.8%) yana kula da ƙarfi da rufi a yanayin zafi; gilashin matsakaici / high-alkali yana haifar da lalacewa. Cikakkiyar kawar da ma'aunin girman sakar yana hana carbonization da delamination. Tsafta kai tsaye yana shafar rayuwar sabis, bin matakin abinci, da amincin lantarki.

Daidaitaccen bushewar masana'anta na fiberglass yana da mahimmanci ga shafi na PTFE na gaba, resin impregnation, ko lamination. Babban jiyya guda uku: cire danshi a 105-120 ° C (10-30 min dangane da nauyin nauyi), tsaftacewa / tsaftacewa na thermal a 300-450 ° C (LOI <0.1%, kaucewa> 500 ° C), da preheating a 60-100 ° C kafin rufewa. Sarrafa daidaituwar zafin jiki na tanda (± 5°C), tilastawa dehumidification, da kare yadudduka da aka yi wa silane ƙasa 110°C. Ajiye busassun masana'anta a cikin jakunkuna da aka rufe ko busassun dakuna (<30°C, <40% RH).

PTFE high-zazzabi masana'anta (Fiberglass mai rufi PTFE) kusan ba shi da sinadarai, amma wasu abubuwa suna haifar da lalata a ƙarƙashin takamaiman yanayi. Harin PTFE kai tsaye yana faruwa tare da narkakken alkali karafa (sodium, potassium), magunguna masu ƙarfi masu ƙarfi (F₂, ClF₃) a yanayin zafi mai zafi, da narkakken alkalis mai ƙarfi sama da 300°C. Lalata kaikaice yana faruwa lokacin da hydrofluoric acid (HF), alkalis mai zafi mai zafi, ko phosphoric acid mai zafi ya shiga cikin lahani kuma ya kai hari ga ma'aunin fiberglass. Don matsanancin sabis na sinadarai, yi amfani da fim ɗin PTFE mai tsabta ba tare da fiberglass ba.

PTFE high-zazzabi masana'anta (PTFE-rufi fiberglass) yana da kyau kwarai thermal girgiza juriya a cikin al'ada aiki kewayon -70 ° C zuwa 260 ° C. Yana iya jure wa hawan keke cikin sauri, misali, motsi daga injin daskarewa -50°C zuwa matsananciyar zafi 260°C. Darajojin ƙima har ma suna tsira da sanyi kwatsam daga 260°C zuwa ruwa 10°C. Koyaya, girgiza kayan daga yanayin zafi sama da 300 ° C (kusa da PTFE's 327°C na narkewa) zai haifar da tsagewa da lalata nan take. Ƙarƙashin fiberglass yana ba da kwanciyar hankali mai girma; da PTFE shafi ne iyakance factor.

PTFE high-zazzabi masana'anta da aka yadu amfani a cikin sinadaran masana'antu for bakwai key aikace-aikace: flange gaskets da bututu rufi (juriya da karfi acid / alkalis), reactor da tanki linings (hana karfe lalata, sauki tsaftacewa), tace bags for lalata flue gas (har zuwa 260 ° C), anti-lalacewa fadada gidajen abinci ga ducts, anti-padssion m, walƙiya tufafi ga ducts, anti-adhesion m, lantarki da kuma m. rufi wraps. FDA da UL maki akwai.

PTFE high-zazzabi masana'anta (PTFE-rufi fiberglass) yayi hudu key abũbuwan amfãni a matsayin anti-lalata rufi: sinadaran inertness (juriya aqua regia, karfi alkalis, kaushi), fadi da zafin jiki kewayon (-70 ° C zuwa 260 ° C ci gaba, 350 ° C ganiya), girma girma (<0.5% ginawa surface), da kuma hana girma da kwanciyar hankali. Ana amfani da shi a cikin bututun sinadarai, hasumiya mai lalata sulfur, tankunan girki, da kayan abinci/pharma. Ana samun maki FDA.
