Izi zimafuna maulendo angapo a impregnation-kuyanika-sintering, ndi liwiro la mzere nthawi zambiri limachepetsedwa kufika 0.3-1 m / min.
3. Mizere yopangira bwino kwambiri yokhala ndi mauvuni owumitsa aatali
Pamene ng'anjo kutalika ndi kutentha madera okwanira, liwiro akhoza ziwonjezeke kwa 3-6 m/mphindi, koma izi zimachititsa kwambiri amafuna zipangizo.
II. Nthawi Yopangira: Zolepheretsa Zowumitsa ndi Kuyimitsa
1. Zowonongeka chifukwa cha kusayanika kokwanira
Ngati nsaluyo ilowa m'gawo lotentha kwambiri la sintering ndi chinyezi chotsalira, madzi amawira mwamphamvu, kutulutsa thovu, mapini, ndi mawanga oyera. Nsaluyo iyenera kuumitsidwa poyamba pa 100-250 ° C.
2. Nthawi yovomerezeka yokhalamo kwa sintering
Tinthu ta PTFE timafunika kusungunuka ndikupanga filimu pa 380-400 ° C, zomwe zimafuna nthawi yokhalamo ya 1-3 mphindi - motalikirapo pansalu zokhuthala. Kusakwanira kwa nthawi kumabweretsa kusamata bwino komanso kusweka.
3. Kuthamanga denga pansi pa utali wokhazikika wa uvuni
Pamene kutalika kwa ng'anjo kumakhala kosasintha, liwiro la mzerewo limatsimikiziridwa mwachindunji ndi nthawi yochepa yofunikira kuumitsa ndi kuyanika. Ichi ndiye chopinga chofunikira kwambiri.
III. Kufananiza Makhalidwe Azinthu Ndi Ma Parameter a Njira
1. Impregnation zolimba zili ndi mamasukidwe akayendedwe
Ma dispersions okhala ndi zinthu zolimba kwambiri komanso kukhuthala kwakukulu amalowa ndikulowa pang'onopang'ono. Kuthamanga kwambiri kwa mzere kumabweretsa kunyamula kosiyana, zomwe zimatsogolera ku mikwingwirima kapena kugwa.
2. ❖ kuyanika makulidwe ndi chiwerengero cha impregnation zikudutsa
Kwa chiphaso chimodzi cha impregnation chokhala ndi zokutira zopyapyala, liwiro la mzere limatha kukhala lalitali. Pazinthu zomwe zimafunikira ma pass angapo kuti zikundikire, liwiro liyenera kukonzedwa bwino pa pass iliyonse, ndipo pass yomaliza imayenda pang'onopang'ono kuti muwonetsetse kuti mukuyenda bwino.
3. Nsalu makulidwe ndi m'lifupi
Nsalu zokhuthala ndi zowundana za fiberglass zimatenga madzi ndikusuntha kutentha pang'onopang'ono, kukulitsa nthawi yowuma ndi yowuma. Nsalu zazikuluzikulu zimakhala zovuta kutentha mofanana, zomwe nthawi zambiri zimabweretsa kusiyana kwamitundu pakati pamphepete ndi pakati, zomwe zimafunika kuchepetsa liwiro.
IV. Kulinganiza Kutha kwa Zida ndi Zofunikira Zapamwamba
1. Utali wa uvuni ndi kasinthidwe kagawo ka kutentha
Mavuvuni aatali okhala ndi mapangidwe amitundu ingapo amatha kukulitsa nthawi yotenthetsera bwino, kulola kuthamanga kwambiri kwa mizere. Mavuni akale achidule amatha kuthamanga pa 1-2 m / min.
2. Kutentha kwachangu komanso kutha mphamvu
Kuthamanga kwa mpweya wotentha ndi chithandizo chakutali cha infrared kumatha kufulumizitsa kuyanika ndi kuyanika. Kutopa kosakwanira kumayambitsa kusungidwa kwa nthunzi, kumabweretsa kuwonongeka kwa pamwamba ndikukakamiza kupanga pang'onopang'ono.
3. Kusinthanitsa mumayendedwe abwino amawonekedwe
Pamene nsalu ya Teflon yotentha kwambiri imafuna ndondomeko zokhwima-popanda pinholes, thovu, ming'alu, ndi kupirira makulidwe olimba-liwiro lochepa ndilofunika kuti mukwaniritse zokolola zambiri, zomwe zimapangitsa kuti liwiro la mzere likhale lokhazikika.
