Ndezvipi zvinokonzereswa nePVC foaming regulators pachimiro chepore yezvigadzirwa?

Chinodzora furo chakagadzirwa neBontecn Group China chinokanganisa zvakananga kuumbwa, kugadzikana, uye chimiro chekupedzisira chepore pore nekudzora hunhu hwepolymer melts. Zviratidzo chaizvo ndeizvi:
1. Kufanana uye kunatswa kwemaburi efuro
Wedzera simba uye kusimba kwekunyunguduka kwechinhu chakanyunguduka, kurudzira kupararira kwakafanana kwegasi muPVC melt, gadzira ma micropores akazvimiririra (dhayamita 0.1-0.5mm), uye deredza dambudziko rekubatana kwemabubble kana kukora. Panguva imwe chete, gadzirisa kubatana kwekunyunguduka kuti uve nechokwadi chekuti madziro esero anokwanisa kumira kumanikidzwa kwegasi uye kuchengetedza kugadzikana kwechimiro chesero rakavharwa.
2. Kuwanda kwemasero uye kutonga saizi
Chiyero chinofanira kuenzaniswa nemazvo: chakanyanya kuderera (<4phr) chinoita kuti simba rekunyunguduka risakwane, zvichikonzera kuputika kwemabubble kana kudonha kwenzvimbo; Kana chakanyanya kukwira (>8phr), chichasimbisa kunyunguduka zvakanyanya, kudzvinyirira kukura kwemabubble, uye panzvimbo pezvo chinowedzera huwandu hwechigadzirwa. Kana huremu hwemamorekuru hwakakwira (senge 530 model), mapores acho akanyanya kupfava uye anoderedza huwandu, asi chinonzwa tembiricha yekugadzirisa.
3. Kudzivirira zvikanganiso zvakakwana uye kugadzirisa chimiro
Kuti udzivise mabubble asina kujairika (akadai semabubble marefu kana maziso ehove), zvakakosha kuronga system yemafuta uye tembiricha yemaitiro: kutsvedza kwakanyanya kwekunze kunoderedza kumanikidzwa kwekunyunguduka uye kukonzera kusagadzikana kwehuwandu hwenzvimbo; Kuchinja-chinja kwetembiricha ye ± 5 ℃ kunogona kukanganisa kufanana kwema pores uye kunoda kuwedzerwa kwezvigadziriso zvakaita se zinc stearate kuti zvikwanise kuenzaniswa.
4. Kuchinjika kwakasimba
Kusarudzwa kwemhando (yakadai seKF-100) yemhando dzakasiyana dzezvigadzirwa (senge machira akaomarara ePVC kana shangu dzakapfava) kunokanganisa zvakananga chimiro cheburi: kune zvigadzirwa zvakapfava, chinodzora chakakosha chinodiwa kudzivirira maronda eganda uye kuvandudza kutwasuka kweganda.
