Abubuwan Bukatu don Kwanciyar Sanyi Lokacin Sintering na PTFE High-Temperature Cloth

I. Abubuwan buƙatun asali don ƙimar sanyaya

Da sauri wucewa ta cikin yankin da ke da ƙima Matsayin narkewar PTFE shine 327 ° C, kuma madaidaicin zafin jiki ya tashi daga 380 ° C zuwa 400 ° C. A lokacin rage yawan zafin jiki, ainihin abin da ake buƙata shine a ƙetare yankin zafin jiki da sauri a kusa da 310 ~ 315 ° C inda ƙimar crystallization ke ƙaruwa sosai.

Hanyoyin aiki da aka ba da shawarar Nan da nan bayan fita daga tanderun da ke murƙushewa, aiwatar da sanyaya iska ta tilas, matsawa iska mai sanyaya iska, ko amfani da na'urorin sanyaya na'urorin sanyaya / na'urorin sanyaya ruwa don sauke yanayin masana'anta da sauri ƙasa da 250°C.

 

Ma'anoni masu sanyaya ra'ayi Dangane da kauri na samfur, ƙimar sanyaya gabaɗaya ba zai zama ƙasa da 30 ~ 50 ° C/min ba. Don bakin ciki-ma'auni high-zazzabi zane (0.08mm ~ 0.25mm), iska sanyaya iya cimma wani sanyaya kudi sama 100 ~ 200 ° C / min, kunna nan take nassi ta cikin m crystallization yankin.

 

II. Injiniyan Tsari: Yadda Matsakaicin Matsayin sanyaya ke Tasirin Ayyukan Samfur

Crystallinity ƙayyadaddun ainihin kaddarorin samfuri Yanayin sanyaya kai tsaye suna sarrafa crystallinity na PTFE, wanda ke ƙara bayyana halayen shafi mai mahimmanci ciki har da sassauci, mannewa da aikin mara amfani.

 

Kwatancen Aiki Tsakanin Sauri da Sanyi Sanyi

Bayanin Microstructural Mai saurin sanyaya yana hana haɓakar manyan spherulites masu girma kuma yana samar da kyakkyawan tsarin microcrystalline. Wannan ya sa PTFE fim denser kuma mafi ductile, yayin da minimizing saura danniya tsakanin shafi da fiberglass substrate.

 

III. Maɓallin Sarrafa Maɓalli a cikin Samar da Jama'a

 

Garanti iri-iri sanyaya sanyaya kwararar iska ko sanyaya rollers dole ne su kiyaye daidaitaccen zafin jiki a fadin masana'anta. Rashin daidaituwar crystallinity na gida zai haifar da ɗumbin filaye ko lahani.

 

Guji gigin zafin jiki mai kauri Don kauri mai zafi mai zafi (0.5mm da sama), fesa ruwa kai tsaye ko tuntuɓar masu sanyi mai tsananin sanyi na iya haifar da nakasu mai tsanani wanda ya haifar da rashin daidaituwar zafin jiki tsakanin ma'auni da shafi. Mafi kyawun aikin aiki shine sanyaya iska mai ƙarfi zuwa ƙasa da 250 ° C kafin ƙarin sanyaya.

 

Gudanar da sanyaya don ƙwanƙwasa mai wucewa da yawa Don haɓakawa da yawa & matakai daban-daban, matsakaicin saurin sanyaya yana karɓa don tsaka-tsakin hawan keke. Duk da haka, mataki na ƙarshe na sintering dole ne ya ɗauki saurin sanyaya don amintaccen aikin aikin saman.

IV. Takaitaccen Bayani

1. Mai saurin sanyaya dole ne bayan PTFE zane sintering don ba da damar narkakkar PTFE don tsallake yankin babban zafin jiki da sauri.

2. Saurin sanyayawar gaggawa yana haifar da tsarin microcrystalline mai ƙarancin kristal, wanda shine mabuɗin don ƙwaƙƙwaran sassauci, juriya na ninka da kuma aikin da ba ya daɗe mai dorewa.

3. Daidaita daidaita daidaiton sanyaya, hana girgizar zafi, da daidaita jadawalin sanyaya don daidaita matakai masu yawa don daidaita daidaiton ingancin samfur.
