PVC pulasitiki mapangidwe,
Utoto wa PVC, PVC utomoni ndi zowonjezera, PVC utomoni kupanga chitoliro, PVC SG-5, PVC SG-8, PVS SG-7,

Mapangidwe apulasitiki a PVC amapangidwa makamaka ndiPVC utomoni ndi zowonjezeras, zomwe zowonjezera malinga ndi ntchitoyo zimagawidwa kukhala: stabilizer kutentha, lubricant, processing modifier, impact modifier, filler, okalamba, colorant ndi zina zotero.Tisanapange mapangidwe a PVC, tiyenera kumvetsetsa kaye za utomoni wa PVC ndi zowonjezera zosiyanasiyana.

Zopangira ndi zowonjezera

PVC utomoni

PVC pulasitiki mbiri kupanga utomoni ndi polyvinyl kolorayidi utomoni (PVC), PVC anapangidwa ndi vinilu kloridi monoma polymerization polima, linanena bungwe lachiwiri kwa Pe, kusanja wachiwiri.

PVC utomoni akhoza kugawidwa mu mtundu lotayirira (XS) ndi zolimba mtundu (ⅺ) chifukwa dispersants osiyana mu polymerization.Lotayira tinthu kukula ndi 0.1-0.2mm, pamwamba ndi osasamba, porous, thonje mpira, zosavuta kuyamwa plasticizer, yaying'ono tinthu kukula ndi pansi 0.1mm, malamulo pamwamba, olimba, tebulo tennis mawonekedwe, si kosavuta kuyamwa plasticizer, ntchito panopa wa mtundu womasuka kwambiri.

PVC akhoza kugawidwa mu kalasi wamba (poizoni PVC) ndi thanzi kalasi '(non poizoni PVC).Zofunikira pazaumoyo za vinyl chloride (VC) zotsika kuposa LOXL0-6, zitha kugwiritsidwa ntchito muzakudya ndi zamankhwala.Kupanga ndondomeko ndi osiyana, PVC akhoza kugawidwa mu kuyimitsidwa PVC ndi emulsion PVC.Malinga ndi dziko muyezo GB/T5761-93 "kuyimitsidwa njira general polyvinyl kolorayidi utomoni anayendera muyezo", kuyimitsidwa njira PVC anawagawa PVC-SGL kuti PVC-SG8JK utomoni, ang'onoang'ono chiwerengero, wamkulu digiri ya polymerization, wamkulu kulemera kwa maselo, kumapangitsa kuti mphamvu ikhale yokwera, koma pamene kusungunuka kumakhala kovuta kwambiri, kukonza kumakhala kovuta kwambiri.Kusankha kwachindunji, kuchita zinthu zofewa, kugwiritsa ntchito PVC-SGL, PVC-SG2, PVC-SG3 mtundu, ndikofunikira kuwonjezera mapulasitiki ambiri.Mwachitsanzo, PVC filimu ntchito SG-2 utomoni, kuwonjezera 50 mpaka 80 mbali plasticizer.Ndipo pokonza zinthu zolimba, musawonjezere kapena kuwonjezera plasticizer pang'ono kwambiri, gwiritsani ntchito PVC-SG4, VC-SG5, PVC-SG6, PVC-SG7, PVC-SG8 kotero.Monga PVC chitoliro cholimba ntchito SG-4 utomoni, pulasitiki chitseko ndi zenera mbiri ntchito SG-5 utomoni, zolimba mandala pepala ntchito SG-6 utomoni, mbiri thovu zolimba ntchito SG-7, SG-8 utomoni.Ndipo emulsion PVC phala zimagwiritsa ntchito chikopa yokumba, wallpaper ndi pansi zikopa ndi kuviika mankhwala pulasitiki.Ena PVC utomoni opanga PVC utomoni malinga ndi digiri polymerization (digiri polymerization ndi chiwerengero cha unyolo, polymerization digiri kuchulukitsa ndi kulemera maselo a unyolo ndi wofanana ndi kulemera maselo a polima) gulu, monga Shandong Qilu petrochemical general chomera. kupanga PVC utomoni, mankhwala fakitale kwa SK-700;SK - 800;SK - 1000;SK - 1100;SK - 1200, etc. The lolingana digiri ya polymerization wa SG-5 utomoni ndi 1000 - 1100. The thupi ndi mankhwala zimatha PVC utomoni kuona chachinayi.

PVC ufa ndi ufa woyera wokhala ndi kachulukidwe ka 1.35 - 1.45 g / cm3 ndi kachulukidwe kowoneka bwino ka 0.4-0.5 g / cm3.Yang'anani kukula kwa zinthu za plasticizer kumatha kukhala kofewa, zinthu zolimba, zomwe zili mu plasticizer 0-5 ndizinthu zolimba, 5-25 ndizinthu zolimba, zopitilira 25 ndi zofewa.

PVC ndi mtundu wa amorphous, polar polima, kufewetsa kutentha ndi kusungunuka kutentha ndi mkulu, koyera PVC zambiri ayenera kukhala 160-210 ~ C plasticizing processing, chifukwa cha polar mgwirizano pakati macromolecules kuti PVC limasonyeza ntchito mwakhama ndi Chimaona.Kuphatikiza apo, mamolekyu a PVC okhala ndi magulu a chlorine, kutentha kukafika 120 ~ C, PVC yoyera imayamba kuchotsa zomwe HCl zimachita, zomwe zingayambitse kuwonongeka kwa PVC.Chifukwa chake, mitundu yonse ya zowonjezera ziyenera kuwonjezeredwa pakukonza kusinthidwa kwa PVC ndikusintha kwamphamvu, kuti zitha kusinthidwa kukhala chinthu chofunikira.

PVC utomoni zimagwiritsa ntchito kupanga mitundu yosiyanasiyana ya filimu woonda (monga tsiku kusindikiza filimu, mafakitale ma CD filimu, ulimi wowonjezera kutentha filimu, kutentha shrinkable filimu, etc.), mitundu yonse ya mbale, pepala, pepala angagwiritsidwe ntchito mankhwala chithuza), mitundu yonse ya mipope, monga sanali poizoni pa chitoliro ulusi chitoliro, mandala payipi, etc.), mitundu yonse ya zinthu zapadera zooneka ngati chitseko, zenera, mbale zokongoletsera, dzenje kubowola botolo (zodzoladzola ndi zakumwa), Chingwe, mitundu yonse ya mankhwala jakisoni ndi chikopa yokumba, zikopa pansi, zidole pulasitiki, etc.

Zibo Junhai Chemical ndiye mthandizi woyamba wa Sinopec Qilu, mtundu waukulu wa PVC motere.
