Xabagta PVC ee tuubada waraabka
Xabagta PVC ee tuubada waraabka,
Dhuumaha waraabka alaabta ceeriin, pvc ee tuubada waraabka,
Dhuumaha waraabka ee PVC:
(1) Tuubbada waraabka ee PVC waxay leedahay caabbinta aashitada oo aad u fiican, caabbinta alkali iyo iska caabbinta daxalka, taas oo aad ugu habboon warshadaha kiimikada.Dusha sare ee tuubada waraabka ee PVC waa siman.Caabbinta dareeraha waa yar tahay, iskudarkeeda qallafsanaantuna waa 0.009 kaliya, taas oo ka hooseysa tuubooyinka kale.Isla heerka socodka isku midka ah, dhexroorka tuubada waa la dhimi karaa.Cadaadiska cadaadiska biyaha, caabbinta cadaadiska dibadda iyo caabbinta saameynta tuubooyinka waraabka ee PVC waa mid aad u sarreeya, taas oo ku habboon injineernimada tuubooyinka xaaladaha kala duwan.Waa mid raqiis ah oo si ballaaran loo isticmaalo.
(2) Tuubada waraabka ee PVC waxay si fiican u raaci kartaa habka koritaanka dalagyada si loo xaqiijiyo waraabka casriga ah.Isticmaalka biyaha ee waraabka waxaa lagu dooran karaa iyadoo loo eegayo qoyaanka gaarka ah ee dalagyada iyo ciidda.
(3) Tuubbada waraabka PVC waa tan ugu gabi ahaanba waxay ku saleysan tahay sifooyinka kweather hadda si loo gaaro sahayda biyaha saxda ah iyo bacriminta xididka farsamooyinka waraabka dalagyada.Tani waxay yarayn kartaa shaqada gacanta.
(4) Tuubbada waraabka ee PVC waxay qaadi kartaa isticmaalka biyaha waraabka ee macquulka ah iyadoo loo eegayo baahida koritaanka dalagga, taas oo hubin karta waraabinta dalagyada waqtiyeysan oo ku habboon oo aasaas adag u ah horumarinta wax-soo-saarka dalagga.
(5) Tuubooyinka waraabka ayaa si weyn looga isticmaalaa magaalooyinka iyo miyiga gudaha iyo dibadda biyaha, hagaajinta biyaha miyiga, waraabka dhul-beereed, dhuumaha gudbinta brine ee warshadaha milixda iyo kiimikada, gudbinta biyaha ee warshadaha aquaculture, hawo miinada, sahayda biyaha iyo dheecaanka, rushaynta dhirta. waraabka iyo mashaariic kale oo waaweyn iyo kuwo yaryar.
Polyvinyl Chloride (PVC) waa xabagta heerkulbeegga toosan ee uu soo saaray polymerization monomer vinyl chloride.Sababo la xiriira kala duwanaanshaha alaabta ceeriin, waxaa jira laba hab oo lagu farsameeyo vinyl chloride monomer calcium carbide habka iyo habka batroolka.Sinopec PVC waxay qabataa laba hab oo ka joojinta, siday u kala horreeyaan Shirkadda Kiimikada Shin-Etsu ee Japan iyo Shirkadda American Oxy Vinyls.Alaabtu waxay leedahay iska caabin daxalka kiimikaad oo wanaagsan, hanti dahaarka korantada oo aad u wanaagsan iyo xasilooni kiimikaad oo wanaagsan.Iyada oo ay ku jirto maadada koloriin sare, maaddadu waxay leedahay dab-demis wanaagsan iyo sifooyin is-deminta.PVC way fududahay in lagu farsameeyo extrusion, qaabaynta duritaanka, calendering, dharbaaxada, isku-buufinta, qaabaynta kabka iyo qaabaynta kulaylka, iwm.
