Mhedzisiro yekuwedzera kweCPE paPVC

1. Zvinhu zvitatu zvikuru zvinokanganisa mashandiro eCPE
Chekutanga, imhando yeCPE inoshandiswa. CPE inowanikwa kubva kupolyethylene ine huremu hwakawanda uye ine simba rekudhonza, asi kubatana pakati peCPE iyi nePVC resin kwakaderera. CPE inowanikwa kubva kupolyethylene ine huremu hwakaderera uye ine simba rekudhonza, uye CPE inowanikwa kubva kupolyethylene ine simba rekudhonza rakanaka.
Chechipiri, ihukuru hwezvinhu zvakabikwa. Kana saizi yezvikamu iri diki zvakanyanya, zviri nyore kugadzira jelly kana clumpy CPE, uye kana saizi yezvikamu yakakura zvakanyanya, kupararira kwechlorine hakuna kuenzana.
Zvakare, ihuwandu hweCPE chlorination. Kana huwandu hwechlorine huri pasi pe25%, haishande zvakanaka nePVC uye haigone kushandiswa semodifier; Kana huwandu hwechlorine huri pamusoro pe40%, inoenderana zvakanaka nePVC uye inogona kushandiswa seplasticizer yakasimba, isingakodzeri semodifier yeimpact; CPE ine chlorine iri pakati pe36-38% ine elasticity yakanaka uye inoenderana zvakanaka nePVC, zvichiita kuti ishandiswe zvakanyanya semodifier yeimpact yePVC. Parizvino, CPE ine chlorine iri pakati pe35% ndiyo inowanzo shandiswa. CPE ine chlorine iri pakati pe35% ine crystallinity yakaderera uye girazi transition temperature, elasticity yakanaka yerabha, uye inoenderana zvakanaka nePVC. Inoshandiswa zvakanyanya semodifier yeimpact yePVC hard products.
2, Mhedzisiro yekuwedzera kweCPE paPVC
Kana huwandu hwekuwedzera huri pasi pemaminitsi gumi, simba re PVC rinokwira nekukurumidza nekuwedzera CPE, asi kuwedzera huwandu hweCPE kunoguma nekuvandudzika kushoma kwesimba re PVC rinokwira. Saka, semushonga unodzivirira kukanganiswa, huwandu hwakakodzera hweCPE hunofanira kuwedzerwa zvikamu 8-10. Sezvo CPE ichiwedzera, simba re PVC rinokwira rinoramba richiderera, nepo kureba pakuputsika kuchiwedzera. Kana kuomarara kuchiratidzwa sechibereko chesimba rekuputsika nekureba pakuputsika, zviri pachena kuti kuomarara kwePVC kuchawedzera zvakanyanya nekuwedzera kwekuwedzera kweCPE.
