- 1.PVC utomoni ufa
Ndizinthu zazikulu zopangira, zopangira thovu m'munsi, zomwe zimapanga pepala la PVC lopangidwa thovu nthawi zambiri limatenga Model SG-8 PVC utomoni.Pamene processing, ndi gelatinization liwiro mofulumira, kutentha processing ndi otsika, khalidwe mankhwala ndi khola, ndi kachulukidwe n'zosavuta kulamulira.Pofuna kukonza khalidwe la mankhwala ndi mosamalitsa kusinthasintha kwa kachulukidwe mankhwala ndi makulidwe, SG-8 PVC utomoni nthawi zambiri ntchito kupanga free thovu ndi Celuka thovu PVC mapepala.
- 2.PVC stabilizer
Kuti muthe kuyika zinthuzo papulasitiki panthawi ya bolodi la thovu la PVC, zinthuzo nthawi zambiri zimatentha kwambiri.Kuonjezera apo, wotulutsa thovu amatulutsanso kutentha kowonongeka panthawi ya kuwonongeka.Zinthu izi zimafuna kuti stabilizer ikhale ndi kukhazikika kwamafuta okwanira kuti zitsimikizire kuti zinthu zili bwino komanso kupanga kwanthawi yayitali. - 3.Foaming regulator
Amapangidwa ndi methyl methacrylate, ethyl acrylate, butyl acrylate, ndi styrene.Kapangidwe kake ka mamolekyu ndi kachigoba kakang'ono.Monga thandizo processing dongosolo chiphunzitso, akhoza mogwira kuchepetsa kutentha plasticizing, kulimbikitsa plasticizing tingati, kusintha plasticizing dzuwa, kusintha mphamvu Sungunulani, kuchepetsa kusungunuka pulsation, kupewa Sungunulani fracture, ndi kwambiri patsogolo kusalala kwa zinthu. .Mfundo yosankhidwa ya chowongolera chotulutsa thovu imaphatikizapo kuthamanga kwa plasticizing, kusungunuka kwamphamvu, ndi kusungunuka kwamadzi.Chifukwa cha zinthu zosiyanasiyana ndondomeko, thovu wowongolera zitsanzo ayenera kusankhidwa malinga ndi makhalidwe osiyanasiyana katundu katundu, monga pepala thovu, wandiweyani thovu pepala, woonda thovu pepala, matabwa pulasitiki thovu pepala, etc. Iwo akhoza kuonetsetsa yunifolomu kusungunula ndi zabwino. bolodi pamwamba khalidwe.Kupatula apo, tiyenera kusankha mafuta abwino amkati ndi akunja ndikuwonjezera zolimbitsa thupi zokwanira pakupanga. - 4.Foaming wothandizira
Chotulutsa thovu ndi zinthu zomwe zimapanga chinthu kukhala cell cell.Itha kugawidwa m'magulu otulutsa thobvu, otulutsa thobvu, komanso otulutsa.Amagwiritsidwa ntchito kwambiri kuwongolera kachulukidwe ndi kuyeza kwa matabwa a PVC. - 5. Wodzaza
Mu dongosolo la formula, mlingo wamba wa calcium carbonate ndi 10 ~ 40 phr.Filler sangagwiritsidwe ntchito ngati chopangira thovu komanso kuchepetsa mtengo wazinthu.Komabe, kuchuluka kwa kuwala kwa calcium carbonate kumapangitsa kuti cell ikhale yofanana, kenako imakhudza mawonekedwe ndi mtundu wazinthu.Pamapeto pake zimapangitsa kuti kachulukidwe kazinthuzo kakhale kovuta kuwongolera, kumawonjezera mtengo wake wonse, ndikuchepetsa kuuma kwa mankhwalawa. - 6.Pigment
Amagwiritsidwa ntchito pokongoletsa bolodi, makamaka yoyera, yofiira, yachikasu, yabuluu, yobiriwira, yakuda, imvi, etc.
