ACR, PVC pokonza thandizo, ali ndi mlingo wochepa koma zotsatira zazikulu. Kodi mumadziwa?

Pankhani yamagulu, PVC processing aids ACR itha kugawidwa m'magulu atatu:

1. Zothandizira pokonza zomwe zimalimbikitsa kupanga pulasitiki: Mtundu uwu wothandizira wothandizira umagwiritsidwa ntchito kwambiri pazinthu zolimba za PVC. Ntchito yake yayikulu ndikulimbikitsa pulasitiki, kukonza mawonekedwe a rheological of the melt ndikuwongolera kubalalitsidwa kwa zowonjezera zina, ndikuwongolera mawonekedwe azinthu.

Zoyenera pazinthu zambiri za PVC monga mbiri, mapaipi, mbale (mipukutu), etc., mlingo wotchulidwa ndi 1-2phr

2. Foaming regulator: Chifukwa cha kulemera kwake kwa maselo, PVC thovu loyang'anira akhoza kwambiri kuonjezera kusungunuka mphamvu PVC zipangizo, potero mogwira kukulunga mpweya thovu ndi kupanga yunifolomu zisa dongosolo kuteteza mpweya kuthawa. PVC foaming regulator imathandizanso kubalalitsidwa kwa zowonjezera zina kuphatikiza zotulutsa thovu, kuwongolera mawonekedwe apamwamba azinthu ndikuwonjezera kuwala.

Oyenera mapepala okhala ndi thovu, ndodo za thovu, mapaipi a thovu, mbiri ya thovu, pulasitiki yamatabwa, ndi zina zotero.

3. Thandizo lopangira mafuta akunja: Lili ndi zinthu zofanana zochotsera zitsulo monga sera ya polyethylene oxidized. Kusiyana kwake ndikuti kumagwirizana bwino ndi PVC. Kumlingo wakutiwakuti, zitha kuonjezera processing plasticizing ntchito ndi kusintha kusungunuka. Thermoforming katundu, ndi kukulitsa kubwereketsa kumakhalabe kosasintha pa extrusion processing, sasintha katundu thermoforming, ndi kuteteza chifunga zotsatira chifukwa lubricant mpweya mu zinthu mandala.

Ndi oyenera mafomu kapena zipangizo ndi mkulu processing zofunika, makamaka mandala mapepala, thovu mbiri, thovu matabwa ndi thovu matabwa mapulasitiki, etc. Buku mlingo 0.5-2phr

Mwachindunji kwa ndondomeko ndi mankhwala, kusungunula elasticity akhoza bwino pa calendering, kulola zinthu otsala yokulungira bwino pakati odzigudubuza awiri; khalidwe lowoneka likhoza kusinthidwa panthawi ya kutulutsa chitoliro, kuchotsa zochitika za "khungu la shark", ndikuwonjezera kuchuluka kwa extrusion; Pa extrusion yowonekera, chiwerengero cha "maso a nsomba" muzogulitsa chimatha kuchepetsedwa kwambiri; pakumangirira jekeseni, kusungunuka kwasungunuka kumachulukira, motero kumachepetsa kuchuluka kwa jekeseni, kuchepetsa zochitika za "mizere yoyera", kuwonjezeka kwa gloss, ndikuwonjezera mphamvu zowotcherera. Ngati zokometsera zikuwonjezedwa Zothandizira kukonza zitha kupititsa patsogolo kuwongolera, kufulumizitsa kuzungulira kwa jekeseni ndikuwonjezera zotulutsa, ndikuletsa "kufalikira" chodabwitsa chifukwa cha kutsetsereka kwakunja; pakuwomba nkhonya, amatha kukonza pulasitiki, kuchepetsa zochitika zamaso, kuwongolera kusungunuka, ndikupanga makulidwe omangirawo ndi ofanana.
