Tasirin Ƙimar Sanyi akan Tef ɗin PTFE

A matsayin ainihin masana'anta na kaset masu zafi mai zafi na PTFE, Jiangsu Aokai New Materials ta haka yana bayyana tasirin hanyoyin kwantar da hankali da ƙimar sanyaya akan aikin kaset ɗin PTFE da aka warke.

I. Mahimmancin Halayen Crystallization na PTFE da Ka'idojin Ƙimar Sanyaya

The PTFE substrate na warke high-zazzabi tef nasa ne Semi-crystalline polymer, wanda jurewa da sauri crystallization a lokacin sanyaya bayan sintering. Mahimmanci, ƙimar sanyaya shine ainihin ma'aunin tsari don sarrafa crystallinity na tef mai zafi mai zafi na PTFE: sanyaya hankali yana kaiwa ga mafi girma crystallinity, yayin da saurin sanyaya yana haifar da ƙananan crystallinity.

II. Tasirin Sanyi Slow akan kaset ɗin PTFE masu zafi

Tasiri kan Matsalolin  Ciki Sannun hankali na iya rage yawan damuwa mai zafi a cikin tef. Lokacin da aka kwantar da tef ɗin ta halitta a cikin tanderun, matrix na PTFE da kwarangwal ɗin fiber gilashi suna da isasshen lokaci don daidaita bambance-bambancen raguwa ta hanyar shakatawa na sarkar kwayoyin halitta, guje wa maida hankali na gida.

Tsarin da aka yarda da shi sosai shine sanyaya tef ɗin a cikin tanderu zuwa 150-200 ℃ kafin fitar da shi don sanyaya iska. Wannan jinkirin tsarin sanyaya yana rage damuwa na ciki yadda ya kamata kuma yana hana lalacewa da fashewa.

Tasiri kan Girman Kwanciyar  sanyi Slow yana inganta kwanciyar hankali sosai. A lokacin jinkirin sanyaya, PTFE kwayoyin sarƙoƙi shirya cikin na yau da kullum crystal lattices isa, forming high crystallinity da kyau-raya crystal hatsi, wanda tabbatar da barga karshe girma.

Ƙarƙashin zafi mai zafi zai faru a ƙarƙashin babban zafin jiki a ainihin amfani, don haka ana bada shawara a ajiye 1% -2% gefe yayin aikace-aikacen. Sannu a hankali yana ba da damar ragewa tare da ƙarancin gurɓataccen gurɓataccen abu.

Tasiri kan Ayyukan Adhesive  Slow sanyaya yana yin tasiri biyu akan kayan mannewa. A hannu ɗaya, yana ba da damar maɗaukakiyar maɗaukaki don kammala haɗin giciye da annashuwa sosai, yana kiyaye ƙarfin haɗin gwiwa. A daya hannun, mafi girma crystallinity qara surface rigidity na PTFE substrate, haifar da mayar da hankali danniya a kan bonding dubawa a karkashin peeling karfi.

III. Tasirin Sanyi Mai Sauri akan kaset ɗin PTFE masu zafi

     Tasiri kan Damuwar Ciki  Saurin sanyaya shi ne babban dalilin yawan damuwa na ciki. Kai tsaye quenching bayan sintering halitta babban zafin jiki bambanci tsakanin PTFE matrix da gilashin fiber tsarin, samar da nan take shrinkage danniya da kuma sauƙi forming lafiya fasa.

Layer na saman yana raguwa kuma yana taurare cikin sauri yayin da Layer na ciki ya kasance yana faɗaɗawa, yana samar da yanayin damuwa na zafi na waje da matsawa na ciki, wanda ke haifar da fashewar tef kai tsaye.

Tasiri kan Tsawon Tsayin Girma  Mai saurin sanyaya yana canza kololuwar ƙirƙira zuwa ƙananan zafin jiki kuma yana rage crystallinity tare da tsarin lu'ulu'u wanda bai cika ba. Tef ɗin yana tsayawa a cikin yanayin daskararre mara daidaituwa bayan ya mutu. Ƙaƙƙarfan crystallization na biyu da bayan raguwa na iya faruwa a ƙarƙashin canje-canjen zafin jiki na gaba, yana haifar da karkatar da girma a hankali.

Tasiri kan Ayyukan Adhesive  Saurin sanyaya yana hana cikakken haɗin giciye na yadudduka manne. An daskarar da manne kafin a samar da cikakkiyar hanyar sadarwa mai alaƙa, yana haifar da raguwar ƙarfin haɗin gwiwa da juriya na zafin jiki.

Ƙarƙashin hawan hawan sanyi da zafi mai maimaitawa, bambance-bambancen haɓakar zafi tsakanin PTFE substrate da m Layer yana haifar da damuwa na tsaka-tsaki, haɓaka tsufa da haɓakawa, kuma yana raunana ƙarfin danko sosai.

IV. Kwatanta hanyoyin sanyaya daban-daban

 

Gabaɗaya, jinkirin jinkirin da kuma sanyaya iri ɗaya shine ainihin ka'ida don maganin bayan-warkar da kaset masu zafi na PTFE. Ana ba da shawarar yin amfani da yanayin sanyaya a cikin tanderu bayan sintering, da kuma fitar da kaset ɗin don sanyaya iska zuwa zafin jiki bayan zafin jiki ya faɗi ƙasa 150-200 ℃. Rashin daidaituwa lokacin samarwa zai haifar da raguwa kuma a ƙarshe yana lalata ingancin samfur.

Abubuwan da ke sama sun samar da su Jiangsu Aokai New Materials Technology Co., Ltd.

Idan kana son sanin cikakkun sigogi, yanayin aikace-aikacen da keɓance hanyoyin samfuran samfuran mu masu cikakken jerin samfuran ciki har da PTFE high-zazzabi zane, PTFE high-zazzabi tef, PTFE high-zazzabi raga bel, sumul fusing inji bel, guda-gefe PTFE masana'anta, high zafin jiki resistant conveyor bel da high zafin jiki resistant fiberglass: Tufafi
