Taxadarrada shaqada foornada jawiga vacuum
Taxaddar hawleedka foornada jawiga vacuum
Foornada jawiga vacuum waa nooc foornada oo la faaruqiyo oo dhaafi karta jawiga. Waxay leedahay noocyo badan oo foorno oo kala duwan sida nooca sanduuqa, foornada tuubada, iyo foornada wax lagu qaado. Inkasta oo ay jiraan noocyo badan, taxaddarrada inta lagu jiro hawlgalka ma xuma. Hoosta aan ogaano:
1. Foornooyinka hawada nadiifka ah ee heerkulka sarreeya lama saari karo si xad dhaaf ah. Heerkulka ugu badan ee hawlgalka waxa loola jeedaa heerkulka dusha sare ee la ogolyahay ee cunsurka faaruqa ku jira, ma aha heerkulka walxaha kulayliyaha ama heerkulka agagaarka walxaha kulaylinta. Waa in la ogaadaa in heerkulka walxaha kuleyliyaha vacuum laftiisa uu 100 ° C ka sarreeyo heerkulka dhexdhexaadka ah ee ku wareegsan ama heerkulka kulaylka.
2. Marka la cabbirayo isku mid ahaanshaha heerkulka foornada jawiga vacuum, fiiro gaar ah u yeelo habka meelaynta heerkulka cabbiraadda xidhiidhka iyo fogaanta walxaha kuleylka. Isticmaal burushyada, xaaqinnada ama hawo cufan, nadiifiyeyaasha faakuumka, iwm. si aad u nadiifiso foornada foornada jawiga si joogto ah (ugu yaraan maalin kasta ama ka hor inta aan la wareejin) si aad uga hortagto wasakhda sida miisaanka oksaydhka ee foornada inay ku soo dhacaan walxaha kuleylka, gaaban- wareegyada, iyo xitaa gubanaya ulaha kululaynta molybdenum . Saxanka hoose, usha kuleylka molybdenum, lakabka dahaarka foornada iyo qaybaha kale ee birta u adkeysata kulaylka waa in la nadiifiyaa mar kasta oo la isticmaalo. Garaacida si adag ayaa mamnuuc ah, waxaana si taxadar leh loo saari karaa miisaankooda oksaydhka.
3. Ka dib marka foornada ay kululaato, nidaamka vacuum si lama filaan ah uma burburin karo, iska daa in la furo albaabka foornada. Ogsoonow in furaha cabbiraadda vacuumku waa in la damiyo ka hor inta aan la buuxin jawiga si looga ilaaliyo cabbirka faakuumka gabowga. Marka heerkulku ka sarreeyo 400℃, waa inaan si degdeg ah loo qaboojin. Iska ilaali falcelinta u dhaxaysa walxaha kuleyliyaha ah iyo alaabta, gaar ahaan haddii naxaasta, aluminium, zinc, tiin, lead, iwm. ay la kulmaan walxaha kuleyliyaha vacuum, hadday tahay budo fiican, dareere dhalaalaysa ama uumi, iwm, si looga hortago nabaad guurka iyo samaynta “godadka” dusha sare ee walxaha kuleylka korontada. , Qaybta iskutallaabtu way yaraataa, wayna gubataa ka dib kulaylka. Marka qaybaha gudbinta la ogaado inay xayiran yihiin, oo aan sax ahayn, iyo xakamaynta xakamaynta, waa in isla markiiba la tirtiraa, oo ha ku qasbin qalliinka si looga fogaado waxyeellada qaybaha.
4. Qaybaha birta u adkaysta kulaylka sida saxanka hoose ee foornada jawiga vacuum, ulo kululaynta molybdenum, lakabka foornada, iwm waa in la nadiifiyaa mar kasta oo la isticmaalo. Garaacista si adag waa mamnuuc, miisaanka oksaydhkana si taxadar leh ayaa looga saari karaa. Haddii miisaanka birta oksaydhka iyo wasakhda kale aan laga saarin wakhtiga, meesha dhalaalaysa waxay ku shidaysaa lakabka dahaarka, taasoo keenaysa in xadhigga molybdenum uu dhalaaliyo.
5. Ka dib marka foornada ay kululaato, nidaamka vacuum si lama filaan ah uma burburin karo, iska daa in la furo albaabka foornada. Ogsoonow in furaha cabbiraadda vacuumku waa in la damiyo ka hor inta aan la buuxin jawiga si looga ilaaliyo cabbirka faakuumka gabowga. Marka heerkulku ka sarreeyo 400℃, waa inaan si degdeg ah loo qaboojin. Walxaha kuleyliyaha faakuumka, way fududahay in ay keento oksaydh (oxidation) marka heerkulku sarreeyo, heerka faakuumku ma fiicna, qabowga iyo isbeddelada kulaylkuna waa weyn yihiin. Foornada kuleylka molybdenum, inta lagu jiro isticmaalka caadiga ah iyo dayactirka, waa in la qaboojiyo ilaa 200 ° C ka hor inta aan la joojin nitrogen-ka ilaalinta. Albaabka foornada waxa kaliya oo laga furi karaa wax ka hooseeya 80 ° C.
6. Nidaamka qaboojinta waa qayb muhiim ah oo ka mid ah foornada jawiga vacuum. Wareegga qaboojinta biyaha waa in la ilaaliyaa iyada oo aan la daboolin, haddii kale heerkulka biyuhu wuxuu kici doonaa oo wuxuu keeni doonaa in mishiinka istaago. Tani waa dhibaato inta badan la iska indho tiro marka foornada jawigu shaqaynayso. Waxa laga yaabaa inay dhaawac weyn u geysato foornada hawada nadiifka ah ee heerkulka sare leh marka aan la ilaalin. Ujeedada daawaynta biyaha qaboojinta iyadoo la kaashanayo burburka nafleyda iyo hababka kiimikaad ayaa ah in la ilaaliyo macdanta iyo in la yareeyo kaydka wasakhda ee tuubada caagga ah, tuubada masraxa iyo jaakada biyaha, si ay biyuhu si habsami leh ugu socdaan. Tan waxaa guud ahaan sameeya qalab toos ah, kaas oo la socon kara dhaqdhaqaaqa biyaha, si toos ah u buuxin kara walxaha kiimikaad, nadiifinta marin biyoodka, oo ku dari kara biyo nadiif ah.
