ACR, iyo PVC yekugadzirisa rubatsiro, ine diki dosi asi ine hombe mhedzisiro. Unoziva here?

Panyaya yezvikamu, PVC kugadzirisa aids ACR inogona kupatsanurwa mumapoka matatu:

1. Zvishandiso zvekugadzirisa zvinokurudzira plastiki: Iri rudzi rwekugadzirisa rubatsiro runoshandiswa zvakanyanya muzvigadzirwa zvePVC zvakasimba. Basa rayo guru nderekusimudzira plastiki, kuvandudza rheological zvimiro zvekunyunguduka uye kuvandudza kupararira kwezvimwe zvinowedzera, uye kuvandudza hunoonekwa hwemhando yechigadzirwa.

Inokodzera akawanda ePVC zvigadzirwa senge profiles, pombi, mahwendefa (mapumburu), nezvimwe, referensi dosage ndeye 1-2phr.

2. Foaming regulator: Nekuda kwehuremu hwayo hwemamorekuru, PVC foaming regulator inogona kuwedzera zvakanyanya kunyunguduka kwePVC zvinhu, nekudaro kunyatsoputira gasi rinopupuma uye kugadzira chimiro chakafanana chezinga rehuchi kudzivirira gasi kutiza. PVC foaming regulator inobatsirawo kupararira kwezvimwe zvinowedzera zvinosanganisira kupupa maajenti, kuvandudza kunaka kwezvigadzirwa uye kuwedzera kupenya.

Inokodzera mapepa ane furo, tsvimbo dzine furo, pombi dzine furo, foam profiles, foamed wood plastic, etc. The reference dosage is 4-8phr.

3. External lubricating processing aid: Iine zvakafanana zvakanaka zvekubvisa simbi zvivakwa seoxidized polyethylene wax. Musiyano ndewekuti ine kuenderana kwakanaka nePVC. Kune imwe nhanho, inogona zvakare kuwedzera kugadzirisa kweplasticizing kuita uye kugadzirisa kunyungudika. Rheological properties, uye kuwedzera kwekubuda kunoramba kusina kuchinjwa panguva ye extrusion processing, haishandure iyo thermoforming zvivakwa, uye inodzivirira hutsi hunokonzerwa nekunaya kwemafuta muzvigadzirwa zvinoonekera.

Inokodzera mafomula kana midziyo ine yakakwira yekugadzirisa zvinodiwa, kunyanya mashizha akajeka, foam profiles, foam board uye mapurasitiki ane furo emapuranga, etc. Reference dosage 0.5-2phr.

Kunyanya kune maitiro uye zvigadzirwa, iyo yakanyunguduka elasticity inogona kuvandudzwa panguva yecalendering, ichibvumira iyo yakasara zvinhu kuti ifambe zvakanaka pakati pema rollers maviri; iyo inooneka yemhando inogona kuvandudzwa panguva yepombi extrusion, kubvisa iyo "shark ganda" chiitiko, uye kuwedzera extrusion rate; Munguva yekujekesa extrusion, nhamba ye "maziso ehove" muchigadzirwa inogona kuderedzwa zvikuru; panguva yekugadzira jekiseni, iyo yakanyunguduka elasticity inowedzera, nekudaro ichidzikisa huwandu hwejekiseni, kuderedza "mitsetse michena" chiitiko, kuwedzera kupenya kwepasi, nekuvandudza simba rekushongedza. Kana lubricity yakawedzerwa Kugadzirisa aids inogona kuvandudza dhizaini, mhanyisa jekiseni kutenderera uye kuwedzera kubuda, uye kudzivirira iyo "kutumbuka" chiitiko chinokonzerwa nekunze kutsvedza; panguva yekuputika, vanogona kuvandudza plasticization, kuderedza fisheye phenomena, kunatsiridza kunyunguduka elasticity, uye kuita The molding ukobvu yakawanda yunifomu.
