Dzimwe nyaya nezve chlorinated polyethylene:

Chlorinated polyethylene (CPE) chinhu chakazara chepolymer chine hupfu chena chitarisiko, chisina chepfu uye chisinganhuhwi. Iyo ine yakanakisa kuramba kwemamiriro ekunze, iyo ozone kuramba, makemikari kuramba, uye kuchembera kuramba, pamwe nekunaka kwemafuta kuramba, kudzoreredza moto, uye mavara emhando. Kuomarara kwakanaka (kuchiri kuchinjika pa -30 ℃), kuenderana zvakanaka nezvimwe zvinhu zvepolymer, tembiricha yekuora yakanyanya, kuora kunoburitsa HCL, inogona kukonzeresa maitiro eCPE.

Nzira yemvura ye chlorinated polyethylene inowanzoshandiswa, iyo ine mari shoma yekugadzira uye kusvibiswa kusina kunaka. Imwe nzira ndeyekumiswa, iyo inenge yakura. Zvemumba zvinogona kuita kuvandudzwa kwechipiri uye kushandiswa nekukurumidza kukura, uye kumhanya kwekuomesa kunokurumidza. Inowanzoshandiswa mumatangi ekuchengetedza uye zvigadziro zvesimbi zvekuvandudza kuchengetedzwa kwekuvaka.

Domestic chlorinated polyethylene (CPE) modhi dzinowanzoonekwa nenhamba dzakaita se135A, 140B, zvichingodaro. Mavara ekutanga 1 ne2 anomiririra crystallinity yasara (TAC value), 1 inomiririra kukosha kweTAC pakati pe0 ne10%, 2 inomiririra TAC. kukosha> 10%, nhamba yechipiri neyechitatu inomiririra chlorine zvirimo, semuenzaniso, 35 inomiririra chlorine ye35%, uye yekupedzisira digit ibhii ABC, iro rinoshandiswa kuratidza huremu hwemamorekuru ezvakagadzirwa PE. A ndiye mukuru uye C ndiye mudiki.

Kufurira kwehuremu hwemamorekuru: Chlorinated polyethylene (CPE) ine huremu hwepamusoro-soro uye huremu hwakanyanya hwekunyungudika mune yayo A-mhando zvinhu. Viscosity yayo inoenderana nePVC zvakanakisa uye ine yakanakisa dispersion mhedzisiro muPVC, ichigadzira yakanaka network senge fomu yekuparadzira. Naizvozvo, CPE's A-mhando zvinhu zvinowanzo sarudzwa sechigadziriso chePVC.

Inonyanya kushandiswa: waya uye tambo (tambo dzemigodhi yemarasha, waya dzakatsanangurwa muUL uye VDE zviyero), hydraulic hose, hose yemotokari, tepi, rubber plate, PVC profile pombi kugadziriswa, magnetic materials, ABS kugadziriswa, nezvimwewo. Kunyanya kuvandudzwa kweindasitiri yewaya netambo uye indasitiri yekugadzira zvikamu zvemotokari zvakafambisa kudiwa kwerabha yakavakirwa CPE kushandiswa. Rubber yakavakirwa CPE yakasarudzika yekugadzira rabha ine yakanakisa dhizaini mashandiro, kupisa kupisa kuokisijeni uye kuchembera ozone, uye yakanakisa murazvo wemoto.

Zvinhu zvinokanganisa kupisa kwekuora kwekupisa kweCPE

Izvo zvinhu zveCPE pachazvo zvine hukama neiyo chlorine yemukati. Kana iyo chlorine yemukati yakakwira, zviri nyore kuora;

Zvinoenderana nekuchena. Kusakwana kubviswa kwevatangi, zvinokonzeresa, acids, mabhesi, nezvimwewo zvinowedzerwa panguva yepolymerization process, kana kutorwa kwemvura panguva yekuchengetedza uye yekufambisa, inogona kuderedza kugadzikana kwepolymer. Zvinhu izvi zvinogona kukonzera kukanganisa kwema molecular ion, uye CPE ine zvimwe zvakaderera molecular uremu zvinhu zvakadai seCl2 neHCl, izvo zvinogona kukurumidza kuparara kwekupisa kweresin;
