Ndekupi kurasikirwa kuchakonzerwa neyakaderedzwa-yemhando chlorethylene CPE muPVC kugadzirisa?

Chlorinated polyethylene (CPE) i chlorinated modification product ye high-density polyethylene (HDPE), inoshandiswa sekugadzirisa kugadzirisa kwePVC, The chlorine content yeCPE inofanira kuva pakati pe35-38%. Nekuda kwekunakisisa kwayo kwemamiriro ekunze, kuramba kutonhora, kuramba kwemurazvo, mafuta kuramba, kukanganisa kupikisa (CPE is elastomer), uye kugadzikana kwemakemikari.

Nekuda kwekunakisisa kwayo kwemamiriro ekunze, kuramba kutonhora, kuramba kwemurazvo, mafuta kuramba, kupikisa (CPE elastomer), uye kugadzikana kwekemikari, pamwe nekuenderana kwayo kwakanaka nePVC, CPE yave inonyanya kushandiswa kugadzirisa inogadzirisa modifier muPVC. processing.
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 neklorination reaction uchishandisa aqueous suspension chlorination method. Mamiriro akakosha eiyi chlorination process isimba rakareruka, initiator dosage, reaction pressure, reaction tembiricha, reaction time, uye neutralization reaction mamiriro. 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.
