Ndedzipi kurasikirwa kunokonzerwa neakaderera-mhando chlorine polyethylene CPE muPVC kugadzirisa

Chlorinated polyethylene (CPE) chigadzirwa cheklorini chekugadzirisa chepamusoro-density polyethylene (HDPE).Sechigadziriso chekugadzirisa PVC, iyo chlorine yemukati yeCPE inofanirwa kuva pakati pe35-38%.Nekuda kwekunaka kwayo kwemamiriro ekunze, kuramba kutonhora, kuramba kwemurazvo, mafuta kuramba, kukanganiswa kwemaitiro (CPE is elastomer), uye kugadzikana kwemakemikari.

1. Molecular Configuration yeHDPE
Nekuda kweakasiyana maitiro maitiro panguva yepolymerization reaction yePE, kune mimwe misiyano mukugadziriswa kwema molecular uye zvimiro zvepolymer HDPE yayo.Izvo zvimiro zveCPE mushure mekunatswa kweHDPE ine zvakasiyana zvivakwa zvakare zvinosiyana.Vagadziri veCPE vanofanirwa kusarudza yakakodzera HDPE yakakosha poda resin kuitira kuti ibudise inokwanisa CPE resin.

2. Chlorination mamiriro, kureva chlorination process
CPE, sePVC processing modifier, inowanzoumbwa ne chlorination reaction uchishandisa aqueous suspension chlorination method.Mamiriro akakosha eiyi chlorination process isimba rakareruka, initiator dosage, reaction pressure, reaction tembiricha, reaction time, uye neutralization reaction conditions.Nheyo yePE chlorination iri nyore, asi iyo chlorination mechanism yakanyanya kuoma.

Nekuda kwekudyara kushoma mumidziyo yekugadzira CPE, zvidyarwa zvidiki zvekugadzira CPE zvakatopararira muChina.Izvi hazvikonzeri chete kusvibiswa kune nharaunda yezvakatipoteredza, asiwo chimwe chezvikonzero zvakakosha zvekusagadzikana kweCPE mhando.

Parizvino, kune huwandu hukuru hwepasi-mhando CPE pamusika.Kazhinji, kune marudzi maviri emhando yakaderera CPE.Imwe imhaka yezvimwe zvidyarwa zvekugadzira zvisina mamiriro ehunyanzvi uye echinyakare chlorination maitiro.Imwe nzira ndeyekusanganisa imwe chiyero che calcium carbonate kana talc powder muCPE kuti iite mumakwikwi asina kunaka.
