Habka joojinta PVC

sharaxaad gaaban:

PVC waa nooc ka mid ah polymer sare oo amorphous ah, kaas oo heerkulkiisu yahay 105-75, halka uu bararayo ama ku milmo ether, ketone iyo aromatics.ºC ilaa miisaankeeda molecular.Marka la barbardhigo balaastikada kale ee caadiga ah, PVC waxay leedahay sifooyinka caabbinta dabka iyo is-deminta, iyo iska caabbinta daxalka kiimikaad ee aad u fiican, hantida korantada, xasiloonida kiimikada iyo heerkulbeegga balaastiga.Kuma milmi karaan biyaha, khamriga,

Xabagta PVC waxaa ka buuxa boorso isku dhafan oo ah warqad kraft ah iyo walxo PP ah oo tolsan, ama bac gudaha ah oo PP maro tolan ah oo gudaha ah oo leh LDPE bac gudaha ah oo filim ku dahaaran, ama guud ahaan.Shaabadda bacdu waa inay dammaanad qaaddaa in alaabtu aanay wasakhayn ama aanay daadin inta lagu jiro gaadiidka iyo kaydinta caadiga ah.Maaddada saafiga ah ee xirmada yar yar waa 25kg halkii kiish, halka xirmo weyni ay tahay 1250kg, 1000kg, 600k ama 500kg.

(1) Xirmooyinka: 25kg net/pp bac, ama bac warqad kraft ah.

Habka hakinta ee soo saarista chloride polyvinyl waa habka ugu muhiimsan ee soo saarida ujeedooyinka guud ee kala duwan iyo darajooyinka aadka u casrisan ee PVC.Nidaamka waxaa la alifay 1935-kii waxaana markii ugu horreysay shati-galiyay WACKER CHEMIE GmbH, mid ka mid ah shirkadihii hore ee waalidka ee Vinnolit.Horumar joogto ah ayaa laga sameeyay cuntada, tayada alaabta iyo tignoolajiyada.Iyada oo ku saleysan waayo-aragnimadan dheer iyo horumarinta joogtada ah, Vinnolit waxay bixin kartaa hab casri ah oo dhaqaale sare leh oo loogu talagalay soo saarista S-PVC adduunka oo dhan.

Dareen-celinta polymerization-ka waxaa lagu fuliyaa qaybo ka mid ah reactors-kicinta ee nooca "waxqabadka sare leh", oo cabbirkoodu yahay ilaa 160 m3 midkiiba.Tirada iyo xajmiga reactors waxay ku xiran tahay awoodda iyo isku dhafka alaabta.Naqshadaynta gaarka ah ee reactor-ka noocan ahi waxa ay ogolaataa in kulayl aad u hufan laga saaro reactor-ka, sidaa awgeed heerarka wax soo saarka sare waxa lagu gaadhi karaa iyada oo aan la isticmaalin tignoolajiyada kondenseriyaha reflux ama biyo la qaboojiyey.

Xaraashka muuqaalka ah ee PVC waa budo amorphous ah oo cad oo cabbirkeedu yahay 60-250um iyo cufnaanta muuqata 0.40-0.60g/ml.Heerkulka caadiga ah, 100g resin wuxuu nuugi karaa balaastiiste 14-27g ah.
Summada QILU ee PVC waxaa lagu soo saaray tignoolajiyada rukhsadda ee Shirkadda Japanese Shinetsu Chemical Company Ltd. iyo Shirkadda American Oxy Vinyls oo leh qalab xirmo la soo bandhigay.14 darajooyin oo badeecooyin leh bandhigyo kala duwan iyo adeegsiyeedyo kala duwan ayaa la samayn karaa iyadoo la dabaqo habka ka joojinta polymerization iyo isticmaalka VCM sida kaydkeeda.
Darajooyinka ugu waaweyn ee QILU sumadda PVC waa: S-700, S-800, S-1000, S-1300, QS-650, QS-800F, QS-850F, QS-1000F, QS-1050P, QS-1200 iyo QS -1350F.
