Ndezvipi zvinorasikirwa zvinokonzerwa neCPE ye chlorinated polyethylene isina kunaka mukugadzirwa kwePVC?

Chlorinated polyethylene (CPE) chigadzirwa chekugadzirisa chlorinated polyethylene (HDPE) chakagadzirwa nehigh-density polyethylene (HDPE). Semugadziri wePVC, huwandu hwechlorine muCPE hunofanira kunge huri pakati pe35-38%. Nekuda kwekusagadzikana kwayo kwemamiriro ekunze, kusatonhora, kusamira kwemurazvo, kusamira kwemafuta, kusamira kwesimba (CPE i elastomer), uye kugadzikana kwemakemikari.

Semugadziri wePVC, huwandu hwechlorine muCPE hunofanira kunge huri pakati pe35-38%. Nekuda kwekudzivirira kwayo mamiriro ekunze akanaka, kudzivirira kutonhora, kudzivirira murazvo, kudzivirira mafuta, kudzivirira kukanganiswa (CPE i elastomer), uye kugadzikana kwemakemikari, pamwe nekubatana kwayo zvakanaka nePVC, CPE yave ndiyo inonyanya kushandiswa mukugadzirisa PVC.

1. Kurongeka kwemamorekuru eHDPE
Nekuda kwemamiriro akasiyana ekuita panguva ye polymerization reaction ye PE, pane misiyano yakati wandei mukugadzirwa kwemamorekuru uye hunhu hwe polymer HDPE yayo. Hunhu hweCPE mushure mekutsvaira chlorine ye HDPE ine hunhu hwakasiyana hunosiyanawo. Vagadziri veCPE vanofanirwa kusarudza ma HDPE chaiwo powder resins akakodzera kuti vagadzire ma CPE resins akakodzera.

2. Mamiriro ekuita chlorine, kureva maitiro ekuita chlorine
CPE, semuchina wekugadzirisa PVC, inowanzo umbwa nekuita kwechlorination uchishandisa nzira ye chlorination yemvura. Zvinhu zvakakosha zveiyi nzira ye chlorination isimba rechiedza, chiyero chekutanga, kumanikidzwa kwe reaction, tembiricha ye reaction, nguva ye reaction, uye mamiriro e neutralization reaction. Nheyo ye PE chlorination iri nyore, asi nzira ye chlorination yakaoma zvikuru.

Nekuda kwemari shoma inoshandiswa mukugadzira CPE, mafekitori mazhinji madiki ekugadzira CPE akatopararira muChina yese. Izvi hazvingokonzere kusvibiswa kwezvakatipoteredza chete, asiwo chimwe chezvikonzero zvakakosha zvekusagadzikana kwemhando yeCPE.

Parizvino, kune huwandu hwakawanda hweCPE yemhando yepasi pasi pamusika. Kazhinji, kune mhando mbiri dzeCPE yemhando yepasi pasi. Imwe inokonzerwa nekuti mamwe mafekitori ekugadzira haana mamiriro ehunyanzvi uye maitiro ekare echlorination. Imwe nzira ndeyekusanganisa huwandu hwakati hwecalcium carbonate kana talc powder muCPE kuti vaite makwikwi asina kunaka.
