Jiangsu Aokai New Materials, ƙwararrun masana'anta na PTFE babban zane mai zafi, yana ba da cikakkiyar gabatarwa. Tsarin impregnating fiberglass masana'anta tare da PTFE watsawa ne core fasaha zuwa ko'ina gashi da sinter polytetrafluoroethylene uwa fiberglass substrate, forming hada kayan featuring high zafin jiki juriya, lantarki rufi da kuma maras sanda yi. Irin waɗannan samfuran ana amfani da su sosai a cikin laminates masu ƙarfi na jan karfe, bel masu ɗaukar zafi masu zafi, kayan membrane na gine-gine da sauran filayen.
Cikakken tsari na asali ya ƙunshi matakai guda bakwai masu mahimmanci kamar haka:
1. Fiberglass Pretreatment (Dewaxing / Desizing)
Wannan shine mataki mafi mahimmanci kafin magani. Ana lulluɓe wani ma'aunin ma'auni (wanda aka fi sani da paraffin wax, abubuwan sitaci) akan filayen fiberglass yayin saƙa; cirewar da bai cika ba zai cutar da haɗin kai tsakanin PTFE da filayen gilashi.
Babban hanyar magani: masana'anta suna ci gaba da wucewa ta cikin tanderu mai zafi don lalatawar thermal a 350 ~ 400 ° C, cikakke oxidizing da lalata duk abubuwan da suka dace.
· Ci gaba da kulawa: Ana kwantar da masana'anta da aka lalata, wani lokaci ana kurkure da ruwa mai tsafta ko abubuwan da ake amfani da su na sinadarai don kawar da saura ash, sannan a bushe don samun farar fata mai tsabta da aka shirya don yin ciki.
2. PTFE Emulsion Formulation
Raw abu: Mahimmanci PTFE watsawa tare da daidaitaccen m abun ciki na kusan 60%.
· Hanyar hadawa: Tsarma ɓangarorin haja da ruwan da aka ƙera zuwa maƙasudin manufa (40% – 55%) dangane da ɗora ruwan guduro da ake buƙata da ɗankowar ciki. Ana ƙara surfactant mai dacewa don haɓaka aikin wetting akan fiberglass; za a iya haɗa kauri don daidaita danko idan ya cancanta.
3. Ciwon ciki
Maƙasudin maƙasudin shine cikakken shigar PTFE emulsion a cikin daure fiber da interstices na masana'anta da aka saka.
1. Hanyar Dip-Squeeze (Mafi yawan karɓuwa): Ana jagorantar masana'anta ta hanyar nadi na nutsewa don cikakken jiƙa a cikin tankin emulsion, sannan ya wuce ta biyu na matsi. Ana sarrafa nauyin sutura ta hanyar daidaita matsa lamba na abin nadi don fitar da wuce haddi da rarraba guduro daidai.
2. Likita Blade Coating: Emulsion yana bazuwa a saman masana'anta ta ruwan wukake na ƙarfe, wanda ya dace da tarwatsewar danko.
4. Bushewa
Tushen da aka yi ciki yana shiga cikin tanda mai bushewa mai zafi mai zafi yana aiki a 100 ~ 150 ° C.
· Manufar: A hankali ƙafe ruwa da m surfactants, forming wani ko da ba tacky bushe fim na PTFE barbashi a kan fiber saman.
Bayanin kula da yanayin zafi: Maɗaukakin zafin jiki da yawa zai samar da fim mai yawa da sauri, yana kama danshi na ciki wanda ke yin vaporizes don haifar da filaye da blisters.
5. Sintering (Thermal Curing)
Nan da nan ana ciyar da busassun masana'anta a cikin tanderun zafin jiki mai zafi don maganin zafi a 360 ~ 390 ° C (har zuwa 400 ° C don wasu maki).
Mechanism : PTFE shine polymer thermoplastic. A yanayin zafi mai nisa sama da wurin narkewa (327 ° C), ɓangarorin PTFE suna narke, gudana da matakin fitar da su don samar da fim mai ci gaba, samun haɗin kai na injiniya da mannewa tare da filayen fiberglass.
· Rarraba mataki: An raba yankin sintering zuwa gangaren dumama, yawan zafin jiki na yau da kullun da sassan sanyaya don ba da garantin cikakkiyar haɗuwa da ƙwayoyin cuta ba tare da lalatawar thermal ba.
6. Multi-Cycle Impregnation & Sintering
Zagaye-zagaye-sintering guda ɗaya kawai yana haifar da ƙusa-ƙusa-ƙasa mai saurin kamuwa da lahani. Don isa ga kauri mai kauri da abun ciki na guduro (misali, 45% – 65% resin loading for high-frequency jan-clad laminate substrates), cikakken jerin impregnation → bushewa → sintering ana maimaita sau 2 zuwa 4 ko fiye. Kowane zagayowar yana ƙara cika gibin fiber kuma yana ƙara kauri, a ƙarshe yana samar da takarda mai yawa mara nauyi mara nauyi.
7. Bayan Jiyya & Iska
1. Gyaran saman: Bayan wucewar sintering na ƙarshe, ana iya amfani da jiyya na corona ko sinadarai na sodium-naphthalene etching don inganta mannewar saman ba tare da ɓata ma'anar ba, yana sauƙaƙe murfin jan karfe na gaba ko na biyu.
2. Gyaran gefen baki da juyi: Ana gyara gefuna na masana'anta kai tsaye, sa'an nan kuma na'urar ɗaukar hoto ta yi rauni sosai.
3. Ingancin dubawa: M gwaji na ƙãre kayayyakin ciki har da tushe nauyi, kauri, tensile ƙarfi, bawo ƙarfi, dielectric akai-akai da na gani surface lahani.
Mahimman Bayanan Sarrafa Tsari
Mahimman sigogi da ke sarrafa ƙimar ingancin samfurin sune: cikakken desizing / dewaxing, cikakken emulsion wetting, bushewar ƙarancin zafin jiki a hankali, madaidaicin yanayin zafin jiki, da daidaiton shafi mai yawa bayan hawan hawan impregnation.
Idan kana so ka sami cikakkun bayanai dalla-dalla, yanayin aikace-aikacen da keɓance hanyoyin don cikakken fayil ɗin samfurin mu ciki har da PTFE high-zazzabi zane, PTFE high-zazzabi m tef, PTFE high-zazzabi raga bel, sumul zafi latsa bel, guda-gefe PTFE masana'anta, high-zazzabi-resistant fiber bayanin lamba da ke ƙasa da zanen fiberglass da ke ƙasa.
Kullum muna bin falsafar sabis na ƙwararru da mutunci, da zuciya ɗaya muna ba da mafita ta masana'antu ta tsaya ɗaya da sabis na abokin ciniki mai tunani ga duk abokan tarayya!
