I. Kutheka Kugwiritsa Ntchito Teflon Nsalu mu Hot Air Circulation Sintering ng'anjo 1. Imagwiritsidwa ntchito ngati khushoni yopanda ndodo mumayendedwe otsika kutentha Pamene kutentha kwa ng'anjo kumayendetsedwa mosamalitsa pansi pa 260 ° C (mwachitsanzo, kuyanika kochepa, kuchotsa zomangira, ndi kuchiritsa slurry), Nsalu ya Teflon yotentha kwambiri imatha kuyikidwa pa malamba a mauna kapena ma tray akuthupi. Katundu wake wabwino kwambiri wosamata umathandizira kugwetsa kosavuta kwa zomatira popanda zomatira zotsalira, kumathandizira kwambiri kutola bwino.
2. Zoletsedwa kwambiri pazikhalidwe zapakati komanso kutentha kwambiri Mng'anjo zoyendera mpweya wotentha zimagwira ntchito pa 300 ° C mpaka 950 ° C. Zinthu za Teflon zimakhala ndi malire opitilira kutentha kwa 260 ° C komanso kulolera kwakanthawi kochepa kwa 300 ° C. Ikatenthedwa, PTFE imawola mwachangu ndikutulutsa mpweya wapoizoni kwambiri monga hydrogen fluoride ndi perfluoroisobutylene, womwe umawononga zida za ng'anjo ndikuyambitsa zoopsa zakupha. Nsalu ya Teflon ndiyoletsedwa m'njira zonse zochitira sintering.
3. Non-negotiable chitetezo mfundo Chiweruzo chokhacho chomwe chimatsimikiziridwa ndi akatswiri opanga nsalu za Teflon zotentha kwambiri ku Jiangsu ndiye kutentha kwakukulu panthawi yonseyi. Ngati kutentha kwa ng'anjo sikudziwika bwino kapena sikungatsimikizidwe pansi pa 260 ° C, kugwiritsa ntchito nsalu sikuvomerezeka muzochitika zilizonse. Palibe ntchito yowopsa yomwe idzachitike potengera zomwe sizikudziwika.
II. Zofunika Kwambiri za Teflon High-Temperature Nsalu 1. Chotsani kukana kutentha Nsaluyi imapangidwa ndi inpregnating fiberglass base basecloth ndi PTFE, nsaluyo imapereka kutentha kosalekeza kwa -70 ° C mpaka 260 ° C ndi kukana kwakanthawi kochepa mpaka 300 ° C. Chizindikiro chokhwima chaumisirichi chimatanthawuza momwe angagwiritsire ntchito njira zochepetsera kutentha ndipo zimabweretsa kulephera mwamsanga pamene malire a kutentha adutsa.
Pafupifupi palibe zinthu zomwe zingamamatire pamwamba pake, zomwe zimapangitsa kuti utomoni, zomatira, ndi inki zichotsedwe. Imalimbana ndi zidulo zolimba kwambiri, ma alkali amphamvu, ndi zosungunulira organic, zokhala ndi zida zochepa zowononga kwambiri monga zitsulo zosungunuka za alkali, ma fluorinating agents otentha kwambiri, ndi aqua regia omwe amatha kuwononga.
3. Zabwino kwambiri zamagetsi ndi makina Ndi mphamvu ya dielectric yayikulu, imakhala ngati chida chabwino kwambiri chamagetsi. Kugundana kwake ndi kocheperako pafupifupi 0.04, kupangitsa kuti ikhale yoyenera pazigawo zoterera. Magalasi a fiberglass amapereka mphamvu zolimba kwambiri komanso kukhazikika kwake, ndipo nsaluyo imatha kusinthidwa kukhala zopumira kapena zolimba.
1. Kupititsa patsogolo kugwetsa zotsatira ndi ukhondo wa mankhwala Nsaluyi imalepheretsa zida zogwirira ntchito kuti zisagwirizane ndi mathireyi, kuonetsetsa kuti pamakhala zinthu zosalala komanso zowoneka bwino, kuchepetsa mitengo yazinthu, komanso kuyeretsa zida. Zimapereka zotsatira zodziwika kwambiri pazigawo zing'onozing'ono zokhala ndi mawonekedwe ovuta kapena chizolowezi chomamatira kwambiri.
2. Mphamvu pakuwongolera kutentha ndi kugawa kwa mpweya Nsalu ya Teflon imakhala ndi kutsika kwamafuta komanso kusungirako kutentha pang'ono, komwe kumachepetsa kutentha kwapansi pazida zogwirira ntchito ndipo kumafunikira nthawi yotalikirapo yosungira kutentha. Nsalu yopumira ya Teflon imalola kulowa kwa mpweya wotentha ndikusokoneza pang'ono kutentha, pamene nsalu yolimba imalepheretsa kutuluka kwa mpweya ndipo imayambitsa kusiyana kwa kutentha kwa m'deralo, zomwe zimafuna kutsimikizira mofanana musanagwiritse ntchito.
3. Zowopsa zomwe zingadzetse chitetezo Kuwonongeka kwakukulu ndiye chiopsezo chachikulu kwambiri. Mipweya yovunda ya fluoride ndi yopanda mtundu komanso yapoizoni kwambiri, ndipo kupuma pang'ono kumatha kupha. Zipangizo ziyenera kukhala ndi mphamvu zowongolera kutentha, ma alarm odziyimira pawokha, komanso makina opumira. Kugwira ntchito mosayang'aniridwa ndikoletsedwa.
IV. Malamulo Ovomerezeka Ogwiritsidwa Ntchito ndi Malangizo 1. Kutsimikizira kutentha kusanachitike Akatswiri opanga nsalu za Jiangsu Teflon amakumbutsa ogwiritsa ntchito kuti atsimikizire kutentha kwakukulu kogwira ntchito ndi kutentha kwathunthu kwa ng'anjo musanagwiritse ntchito, onetsetsani kuti kutentha sikudutsa 260 ° C, ndikusunga zolemba zonse.
2. Kukonzekera kwathunthu kwa chitetezo Ikani ma alamu otenthetsera kutentha kwambiri ndi zida zozimitsa mwadzidzidzi kuti muzitha kupuma bwino. Ogwira ntchito ayenera kudziwa njira zoyankhira mwadzidzidzi komanso kukhala ndi zida zodzitetezera.
3. Kusankhidwa kwapadera kwa kapangidwe ka mpweya Kuti muchepetse kusokonezeka kwa kayendedwe ka mpweya wotentha, nsalu ya Teflon yopumira imalimbikitsidwa kwambiri. Yang'anani nthawi zonse pamwamba pa nsaluyo kuti isinthe mtundu, kuwira, ndi kuwonongeka, ndipo siyani kugwiritsa ntchito ndikusintha zinthu zomwe zawonongeka nthawi yomweyo zikapezeka.
Zomwe zili pamwambazi zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Material Technology Co., Ltd.
Kuti mumve zambiri pazambiri zatsatanetsatane, mawonekedwe ogwiritsira ntchito ndi mayankho makonda azinthu zathu zonse kuphatikiza nsalu yotentha ya Teflon, tepi yomatira yotentha kwambiri ya Teflon, lamba wotentha kwambiri wa Teflon, lamba wamakina opanda msoko, nsalu imodzi ya PTFE, nsalu yotchinga ndi magalasi apamwamba, chonde osamva kutentha kwagalasi omasuka kulankhula nafe.
