Gabatarwa ta a Teflon High-Temperature Fabric Manufacturer zuwa Bambanci Tsakanin PTFE Emulsions Samar da Daban-daban Polymerization Tsari (Dakatar Polymerization da Watsawa Polymerization)
I. Bayanin Farko na Ra'ayoyi
A cikin aikin masana'antu, polymerization dakatarwa ba zai iya samar da emulsion PTFE kai tsaye ba. Gaskiyar emulsion PTFE (watsawa) ana samarwa ta hanyar watsawa polymerization kawai (wanda shine ainihin emulsion polymerization). Jiangsu Teflon High-Temperature Fabric Manufacturer ya lura cewa kasuwanci samuwa 'takaddawa-hanyar PTFE emulsion' shi ne a zahiri wani ruwa mai ruwa dakatar sanya ta mechanically dispersing dakatar-polymerized guduro micropowders. Biyu sun bambanta asali, daga yanayin barbashi zuwa aikace-aikacen amfani na ƙarshe.
II. Watsawa Polymerization: Primary PTFE Emulsion
1. Barbashi Ilimin Halitta da Kwanciyar Hankali
A barbashi ne daidai mai siffar zobe, kafa ta agglomeration na firamare barbashi (0.05-0.5 μm) cikin sakandare barbashi tare da barbashi girman 0.1-0.3 μm da wani musamman kunkuntar size rarraba. Ana samar da kwanciyar hankali ta hanyar perfluorinated surfactants (PFOA madadin) da aka ƙara yayin polymerization. Tsarin colloidal na iya zama karko ba tare da rarrabuwa ba tsawon shekaru kuma yana nuna kyakkyawan juriya ga juriya na inji.
2. Nauyin Kwayoyin Halitta da Abubuwan Samar da Fim
Nauyin kwayoyin yana da girma sosai (har zuwa miliyan da yawa), tare da crystallinity wanda ya wuce 94% da ƙarfin fibrillation mai ƙarfi sosai. Bayan shafa, ana buƙatar sintering high-zazzabi a kusan 380 ° C, yayin da barbashi ke haɗawa cikin fim mai ci gaba, mai yawa, da tauri tare da kyawawan kaddarorin anti-lalata da mara amfani.
3. Yawan aiki da aikace-aikace
Ana iyakance sarrafawa zuwa manna extrusion, impregnation, ko shafi wanda ke biye da sintering. Aikace-aikace na yau da kullun sun haɗa da rigunan kayan dafa abinci marasa sanda, ɓarkewar membranes na gine-ginen fiberglass, membranes ePTFE microporous (mai numfashi da mai hana ruwa), da manyan fina-finai na capacitor.
III. Dakatar da Polymerization Micropowders: Dakatar da ruwa mai ruwa (Sau da yawa Ana bata sunan Emulsion)
1. Barbashi Ilimin Halitta da Kwanciyar Hankali
Kamar yadda Jiangsu Teflon Babban Zazzabi Fabric Manufacturer ya lura: Barbashi ana samar da su ta hanyar nika da murkushe dakatarwa-polymerized pellets, haifar da saba polyhedral siffofi da barbashi masu girma dabam jere daga 2 zuwa 20 μm da wani m size rarraba. Tsarin ba shi da kwanciyar hankali kuma yana da haɗari sosai ga lalatawa da haɓakawa. Dole ne a ƙara abubuwan surfactants na al'ada da masu kauri irin su xanthan danko da ethers cellulose don rage lalata, kuma ana buƙatar cikakken motsawa kafin amfani.
2. Nauyin Kwayoyin Halitta da Abubuwan Samar da Fim
Za'a iya daidaita nauyin kwayoyin halitta zuwa ƙananan kewayo (dubu dubu zuwa ɗaruruwan dubbai), tare da ɓarna mafi girma da ƙarancin fibrillation. Bayan shafa, kawai na yanayi ko ƙananan zafin jiki ana buƙatar bushewa don samar da busassun busassun lubricating; ba za a iya sanya shi cikin fim ba.
3. Yawan aiki da aikace-aikace
Ana iya shigar da shi kai tsaye cikin abubuwan da aka tsara ko kuma a yi amfani da shi ta hanyar shafa da bushewar iska. Aikace-aikace sun haɗa da abubuwan da ake ƙara mai na masana'antu, roba da na'urori masu sakin filastik, magungunan rigakafin sawa da zamewa don tawada da sutura, da ƙarewar ruwa mai hana ruwa.
IV. Magana mai sauri: Bambance-bambancen Mahimmanci
Asalin Barbashi
Rarraba polymerization barbashi: kafa a-wuri zuwa mai siffar zobe siffofi via watsawa polymerization;
Barbashi hanyar dakatarwa: ƙasa daga guduro mai girma zuwa granules marasa tsari.
Girman Barbashi
Raw watsawa emulsion: 0.1-0.3 μm tare da kunkuntar barbashi size rarraba;
Ruwan dakatarwa: 2-20 μm tare da rarraba girman girman barbashi.
Ruwan dakatarwa: surfactants na al'ada da masu kauri.
Kayayyakin Kirkirar Fim
polymerization watsawa: siffofin ci gaba, m fim bayan high-zazzabi sintering;
Ruwan dakatarwa: ba mai yin fim ba, kawai yana ba da busasshiyar mai mai.
Babban Aikace-aikace
Polymerization watsawa: suturar da ba ta da tsayi, suturar lalata, fina-finai masu aiki;
Ruwan dakatarwa: jami'an hana gogayya, abubuwan sakin, abubuwan da ke jurewa lalacewa don tawada.
Kammalawa daga Jiangsu Teflon High-zazzabi Fabric Manufacturer: Idan aikace-aikace na bukatar impregnation, shafi sintering, ko fim samuwar, dole ne ka zabi na farko PTFE emulsion samar da watsawa polymerization. Idan kawai kuna buƙatar haɓaka lubricity, kaddarorin sakin, ko juriya na abrasion ba tare da sintiri ba, to, dakatarwar mai ruwa da aka yi daga dakatarwa-polymerized micropowders zaɓi ne mai dacewa.
Idan kuna son ƙarin koyo game da cikakkun bayanai dalla-dalla, yanayin aikace-aikacen, da gyare-gyaren gyare-gyare don cikakkun samfuran samfuranmu-ciki har da Teflon yadudduka masu zafin jiki, Teflon tef ɗin zafin jiki, Teflon high-zazzabi raga bel, kabu-sealing inji sumul bel, guda-gefe PTtemper yadudduka, high-gefe belt, high-hannun PTFE masana'anta. fiberglass masana'anta - don Allah a ji daɗin tuntuɓar mu ta hanyar masu zuwa:
A koyaushe muna ɗaukan ƙwararrun falsafar sabis da ke tafiyar da mutunci, kuma mun himmatu don samar muku da mafita ta tsayawa ɗaya da sabis na kulawa!
