1, ptfe musoro nyere muromo kugadzirwa
PTFE pombi welding pamisoro yekuisa chisimbiso kune chekutanga pane zvese, isu tinofanirwa kugadzira PTFE yekuisa chisimbiso chemusoro muromo, zvinoenderana nehukuru hweiyo dhayamita dhayamita yesimbi musoro uye zvichienderana neimwe chikamu nekushandisa hupfu hwekuumba muitiro kugadzira nozzle, maawa masere e sintered pasi pe380 plus. kana kubvisa 5 madhigirii Celsius, mushure mekupedzwa kweiyo sintering yakanaka nozzle ine lathe mota kune saizi chaiyo, kune makorokoto ePTFE chubhu panguva ino yawapedza.
2, ptfe musoro kuvhura
Isa musoro wakabudiswa mumusoro wesimbi, uye shandisa musimboti wekufambiswa kwechiedza kuti uvhure musoro zvakanaka, teerera kune musoro weptfe unofanirwa kuenderana nemusoro wesimbi, kana midziyo yekupedzisira inotapukira, kuputika uye dzimwe njodzi dzinogona kuitika. .
3, ptfe pombi muromo welding
Nematanho maviri ekutanga, tinogona kuita PTFE welding.Pano tinoziva kuti kune nzira mbiri dzekushongedza (hot pressure welding uye hot air welding).Tichavatsanangura mumwe nemumwe.
(1) hot pressure welding
Pamberi pekupisa kudzvinyirira welding tinofanira kuziva ruzivo rwakakosha rwezvinyorwa, kupisa kunopisa kunopisa rudzi rwekupisa kunopisa, kupa kupisa kwakakwana uye zvakakwana pressure.Here, tinofanira kuve nechokwadi chokuti kupisa kwekushisa kwekushisa kunofanira kusvika 673.15k uye kudzvinyirira kunosvika 1-2mpa. .Nokudaro, kuitira kuti tive nechokwadi chekuputira, tinoda kugadzira molds dzinoenderana kuti tive nechokwadi chekupedzwa kwekupisa kwekupisa kwekupisa.
(2) kupisa mweya welding
Saizvozvo, ptfe hot air welding imhando yekupisa inopisa, iyo iri nyore kwazvo kupfuura kupisa kudzvanywa kwemhepo uye haidi mold dzakawanda.Mushure mekuisa muromo wepombi, PFA welding rod uye inopisa air welding pfuti yakakwira kupfuura 713K inoshandiswa preheat PFA kutanga yozoiisa pamusono wewelding kuti irambe ichiita welding.
Cherechedza: ingave iri kupisa kumanikidziro welding kana kupisa kwemhepo welding welding tembiricha ichave yakakwirira kudarika nzvimbo yekunyunguduka ye ptfe, ptfe inogoneka pasi pekushisa kwekushisa, inogadzira mukugadzirwa kwe pyrolysis perfluorinated isobutylene nemamwe magasi ane chepfu, saka welding inofanira kunge iri mukati. nzvimbo yekufefetera, kana mamiriro acho asingatenderi akadai seaya mana fluorine lining tank welding mukugadzirwa anofanira kushandisa fan air supply air flow assurance uye kupfeka gasi mask kuti ive nechokwadi chekuchengetedza panguva imwe chete.
