Xabagta soo saarista profiles caag ah oo PVC ah waa polyvinyl chloride resin (PVC).Polyvinyl chloride waa polymer ka samaysan vinyl chloride monomer.
Xabagta PVC waxaa loo kala saari karaa laba nooc, nooc dabacsan (XS) iyo nooc is haysta (XJ), taas oo ku xidhan wakiilka kala firdhiya ee polymerization.Cabbirka walxaha dabacsan waa 0.1-0.2mm, dusha sare waa mid aan joogto ahayn, dalool, suuf u eg, fududahay in la nuugo balaastiigga, cabbirka walxaha is haysta waa ka yar yahay 0.1mm, dusha sare waa mid joogto ah, adag, tennis miiska, adag tahay in la nuugo caagagga, At hadda, noocyo badan oo dabacsan ayaa la isticmaalaa.
PVC waxa loo qaybin karaa darajada caadiga ah (PVC sunta ah) iyo heerka fayadhowrka (PVC ee aan sunta ahayn).Darajada nadaafadda waxay u baahan tahay maadada vinyl chloride (VC) oo ka yar 10 × 10-6, kaas oo loo isticmaali karo cuntada iyo daawada.Nidaamyada synthetic ee kala duwan, PVC waxaa loo qaybin karaa xayiraadda PVC iyo emulsion PVC.Marka loo eego heerka qaranka GB/T5761-93 "Heerka kormeerka ujeedo-guud ee xuubka chloride polyvinyl ee habka hakinta", habka joojinta PVC wuxuu u qaybsan yahay PVC-SG1 ilaa PVC-SG8 sideed nooc oo xabagta ah, halkaas oo tirada yar heerka weyn ee polymerization, miisaanka kelli sidoo kale waa xoog weyn, sare socodka dhalaalka, iyo aad u adag ka baaraandegi.
Marka la dooranayo badeecad jilicsan, PVC-SG1, PVC-SG2, iyo PVC-SG3 ayaa guud ahaan la isticmaalaa, waxaana loo baahan yahay in lagu daro qadar badan oo caag ah.Tusaale ahaan, filimka polyvinyl chloride wuxuu ka samaysan yahay SG-2 resin, iyo 50 ilaa 80 qaybood oo caag ah ayaa lagu daraa.Marka la farsameynayo alaabada adag, caagadaha guud ahaan laguma darin ama laguma darin qadar yar, sidaas darteed PVC-SG4, PVC-SG5, PVC-SG6, PVC-SG7, iyo PVC-SG8 ayaa la isticmaalaa.
Tusaale ahaan, xabagta SG-4 waxaa loo isticmaalaa tuubooyinka adag ee PVC, SG-5 waxaa loo isticmaalaa albaabka caagga ah iyo profile daaqadda, SG-6 waxaa loo isticmaalaa filim hufan oo adag, iyo SG-7 iyo SG-8 ayaa loo isticmaalaa profile xumbo adag.Habka emulsion koollada PVC waxaa inta badan loo isticmaalaa maqaar macmal ah, wallpaper, maqaar sagxada iyo alaabta caag ah.Qaar ka mid ah soosaarayaasha xabagta PVC waxay u raraan xabagta PVC iyadoo loo eegayo heerka polymerization (shahaadada polymerization waa tirada isku xirka unugga, heerka polymerization lagu dhufto miisaanka kelli ee silsiladdu waxay la mid tahay miisaanka molecular ee polymer), sida PVC xabagta ay soo saartay Shandong Qilu Petrochemical Plant, wax soo saarka warshadda Waa S-700;S-800;S-1000;S-1100;S-1200.
Xabagta SG-5 waxay leedahay shahaado polymerization ka 1,000 ilaa 1,100.Budada PVC waa budo cad oo cufnaanta u dhaxaysa 1.35 iyo 1.45 g/cm3 iyo cufnaanta muuqata ee 0.4 ilaa 0.5 g/cm3.Waxaan u aragnaa waxyaabaha ku jira balaastikada alaabada PVC sida alaab jilicsan oo adag.Guud ahaan, waxyaabaha ku jira balaastikada waa 0 ~ 5 qaybood oo loogu talagalay alaabada adag, 5 ~ 25 qaybaha alaabta adag, iyo in ka badan qaybaha 25 ee alaabta jilicsan.
Kiimikada Zibo Junhai waa alaab-qeybiyaha ugu sarreeya ee Pvc Resin.Waxaan ku siin karnaa PVC xabagta S3, PVC xabagta SG5, PVC xabagta SG8, PVC xabagta S700, PVC xabagta S1000, PVC xabagta S1300 ext.Oo waxay ka timid soo saarayaasha ugu sarreeya ee Shiinaha, Sida Erdos PVC Resin, Sinopec PVC Resin, Beiyuan PVC Resin, Xinfa PVC Resin, Zhong tai PVC Resin, Tianye PVC Resin.ext.
Polyvinyl chloride waxay leedahay sifooyin aad u wanaagsan oo ah alaabta ceeriin ee badan (saliid, dhagax nuurad, kookaha, milixda iyo gaaska dabiiciga ah), habka wax soo saarka ee bislaaday, qiimo jaban, iyo adeegsiyeedyo kala duwan.Waxa ay noqotay xabagta labaad ee ugu wayn ee ujeedo-guud ee aduunka kadib xabagta polyetylen.29% wadarta guud ee isticmaalka xabagta synthetic ee adduunka.Polyvinyl chloride waa sahlan tahay in la farsameeyo waxaana lagu farsamayn karaa qaabaynta, laminating, duritaanka qaabaynta, extrusion, calendering, dharbaaxada, iwm. sida bacaha adag sida taarikada, albaabada iyo daaqadaha, tuubooyinka iyo valves.
