Xabagta PVC, Xabagta PVC iyo wax lagu daro, Xabagta PVC ee soo saarista tuubooyinka, PVC SG-5, PVC SG-8, PVS SG-7,
Samaynta balaastikada PVC waxay inta badan ka kooban tahayXabagta PVC iyo wax lagu daros, kuwaas oo lagu daro sida ku cad shaqada loo qaybiyaa: xasilinta kulaylka, saliidaha, farsamaynta beddelka, wax ka beddelka saamaynta, buuxinta, wakiilka gabowga, midabka iyo wixii la mid ah.Ka hor inta aan la naqshadayn samaynta PVC, waa in aan marka hore fahamno sifooyinka PVC iyo waxyaalaha lagu daro ee kala duwan.
Walxaha ceeriin iyo waxyaabaha lagu daro
Xabagta PVC
Wax soo saarka caaga ah ee PVC ee xabagta waa polyvinyl chloride resin (PVC), PVC wuxuu ka samaysan yahay vinyl chloride monomer polymerization polymer, wax soo saarka labaad ee kaliya ee PE, darajada labaad.
Xabagta PVC waxaa loo qaybin karaa nooca dabacsan (XS) iyo nooca cidhiidhiga ah (ⅺ) taas oo ay ugu wacan tahay kala firdhisyada kala duwan ee polymerization.Cabbirka walxaha dabacsan waa 0.1-0.2mm, dusha sare waa mid aan joogto ahayn, dalool, kubad suuf ah, fududahay in la nuugo caagagga, cabbirka walxaha is haysta wuxuu ka hooseeyaa 0.1mm, xeerarka dusha sare, adag, qaabka miiska miiska, ma fududa in la nuugo caagagga, isticmaalka hadda nooc dabacsan oo dheeraad ah.
PVC waxaa loo qaybin karaa fasalka caadiga ah (PVC sunta ah) iyo heerka caafimaadka '(PVC aan sun ahayn).Shuruudaha heerka caafimaadka ee ka kooban vinyl chloride (VC) oo ka hooseeya LOXL0-6, ayaa loo isticmaali karaa cuntada iyo daawada.Habka synthetic waa ka duwan yahay, PVC waxaa loo qaybin karaa hakinta PVC iyo emulsion PVC.Marka loo eego heerka qaran GB/T5761-93 "habka joojinta guud ee xajinta koloriinta polyvinyl", habka ka joojinta PVC wuxuu u qaybsan yahay PVC-SGL ilaa PVC-SG8JK resin, tirada yar, heerka weyn ee polymerization, weyn Miisaanka kellika ah, xoogga sare, laakiin aad u adag socodka dhalaalka, ka baaraandegidu sidoo kale aad ayey u adag tahay.Doorashada gaarka ah, samee alaabada jilicsan, isticmaalka guud ee PVC-SGL, PVC-SG2, nooca PVC-SG3, waxay u baahan yihiin in lagu daro tiro badan oo caag ah.Tusaale ahaan, filimka PVC ee isticmaalaya SG-2 resin, isagoo ku daraya 50 ilaa 80 qaybood oo caag ah.Oo marka aad farsamaynayso alaabta adag, ha ku darin ama ku darin balaastiiste qadar aad u yar sida caadiga ah, isticmaal PVC-SG4, VC-SG5, PVC-SG6, PVC-SG7, PVC-SG8 sidaas darteed.Sida tuubooyin adag oo PVC ah oo isticmaalaya xabagta SG-4, albaab caag ah iyo profiles daaqadaha iyadoo la isticmaalayo SG-5 resin, xaashida hufan ee adag ee isticmaalaya SG-6 resin, profiles xumbo adag oo isticmaalaya SG-7, SG-8 resin.Iyo koollada PVC emulsion waxaa inta badan loo isticmaalaa maqaar macmal ah, wallpaper iyo maqaar sagxadda iyo alaabta caag ah maquufin.Qaar ka mid ah soosaarayaasha xabagta PVC ee xabagta PVC iyadoo loo eegayo shahaadada polymerization (shahaadada polymerization waa tirada silsiladda cutubka, shahaadada polymerization lagu dhufto miisaanka kelli ee silsiladdu waxay la mid tahay miisaanka molecular ee polymer) kala soocidda, sida Shandong Qilu warshadda guud ee petrochemical wax soo saarka xabagta PVC, alaabta warshadaha ee SK-700;SK - 800;SK - 1000;SK - 1100;SK - 1200, iwm. Heerka u dhigma ee polymerization of SG-5 resin waa 1000 — 1100. Qalabka jireed iyo kiimikaad ee xabagta PVC waxay arkaan tan afaraad.
Budada PVC waa budo cad oo leh cufnaanta 1.35 - 1.45 g/cm3 iyo cufnaanta muuqata ee 0.4-0.5 g/cm3.U fiirso cabbirka balaastikada waxay noqon kartaa mid jilicsan, alaab adag, caagagga guud ee 0-5 waa alaab adag, 5-25 waa alaab adag, in ka badan 25 waa alaab jilicsan.
PVC waa nooc ka mid ah amorphous, polymer polar, heerkulka jilcin iyo heerkulka dhalaali waa sarreeyaa, PVC saafi ah guud ahaan waa in ay ahaataa in 160-210 ~ C balaastiigga processing, ay sabab u tahay bond polar u dhexeeya macromolecules si PVC muujinaysaa waxqabadka adag iyo jilicsan.Intaa waxaa dheer, molecules PVC oo ay ku jiraan kooxaha koloriin, marka heerkulku gaaro 120 ~ C, PVC saafi ah ayaa bilaabi doonta inay ka saarto falcelinta HCl, waxay u horseedi doontaa hoos u dhaca kulaylka ee PVC.Sidaa darteed, dhammaan noocyada wax-ku-kordhinta waa in lagu daraa habka wax-ka-beddelka PVC-ga iyo wax-ka-beddelka saameynta, si loogu habeeyo badeecad waxtar leh.
Xabagta PVC waxaa inta badan loo isticmaalaa soo saarista noocyo kala duwan oo filim khafiif ah (sida filimka daabacaadda maalinlaha ah, filimka baakadaha warshadaha, filimka aqalka dhirta lagu koriyo, filimka kulaylka, iwm), dhammaan noocyada saxan, xaashida, xaashida waxaa loo isticmaali karaa wax soo saarka bilister ah), dhammaan noocyada tubooyinka, sida kuwa aan sun ahayn tuubada dunta, tuubada hufan, iwm), dhammaan noocyada kala duwan ee walxaha gaarka ah, sida albaabka, daaqada, saxan qurxinta, dhalada godan (loogu qurxiyo iyo qurxinta). cabbitaannada), Cable, dhammaan noocyada kala duwan ee alaabta la isku duro iyo maqaar macmal ah, maqaar sagxadda, alaabta lagu ciyaaro caaga ah, iwm.
Kiimikada Zibo Junhai waa wakiilka ugu horreeya ee Sinopec Qilu, astaanta ugu weyn ee PVC sida soo socota.
