Dzimwe nyaya dzine chekuita ne chlorinated polyethylene:

Chlorinated polyethylene (CPE) chinhu chakagadzirwa nepolymer chakazara chine chitarisiko cheupfu huchena, hachina chepfu uye hachinhuwi. Chine simba rakanaka rekudzivirira mamiriro ekunze, chinodzivirira ozone, chinodzivirira makemikari, uye chinodzivirira kukwegura, pamwe nekudzivirira mafuta zvakanaka, chinodzivirira murazvo, uye hunhu hwekupenda. Kusimba kwakanaka (kuchiri kuchinjika pa -30 ℃), chinoenderana zvakanaka nezvimwe zvinhu zvepolymer, tembiricha yakanyanya kuora, kuora kunogadzira HCL, iyo inogona kukonzera dechlorination reaction yeCPE.

Nzira yemvura ye chlorine polyethylene ndiyo inowanzo shandiswa, iyo ine mari shoma yekugadzira uye kusvibiswa kwakashata. Imwe nzira inzira yekumisa, iyo yakakura zvishoma. Dzimba dzemumba dzinogona kugadzirwa uye kushandiswa nekukurumidza, uye kumhanya kwekuomesa kunokurumidza. Inowanzoshandiswa mumatangi ekuchengetera zvinhu nesimbi kuti pave nekuchengetedzeka pakuvaka.

Mhando dzemumba dzepolyethylene ine chlorinated (CPE) dzinowanzo zivikanwa nenhamba dzakadai se135A, 140B, nezvimwewo. Nhamba dzekutanga 1 ne2 dzinomiririra residual crystallinity (TAC value), 1 inomiririra TAC value iri pakati pe0 ne10%, 2 inomiririra TAC value>10%, nhamba dzechipiri nedzechitatu dzinomiririra chlorine content, semuenzaniso, 35 inomiririra chlorine content ye35%, uye nhamba yekupedzisira ibhii rekuti ABC, rinoshandiswa kuratidza huremu hwemorekuru hwezvinhu zvisina kugadzirwa zvePE. A ndiyo hombe uye C ndiyo diki.

Kupesvedzera kwehuremu hwemamorekuru: Chlorinated polyethylene (CPE) ine huremu hwepamusoro hwemamorekuru uye viscosity yakanyanya kunyunguduka muzvinhu zvayo zverudzi rweA. Viscosity yayo inoenderana zvakanyanya nePVC uye ine mhedzisiro yakanaka yekupararira muPVC, ichigadzira network yakanaka sekupararira. Saka, zvinhu zverudzi rweA zveCPE zvinowanzo sarudzwa sechigadziriso chePVC.

Inonyanya kushandiswa pa: waya netambo (tambo dzemugodhi wemarasha, waya dzakatarwa muUL neVDE standards), hydraulic hose, vehicle hose, tepi, rabha plate, PVC profile pipe modification, magnetic materials, ABS modification, nezvimwewo. Kunyanya kukura kweindasitiri yewaya netambo uye indasitiri yekugadzira zvikamu zvemotokari kwakaita kuti pave nekudiwa kwekushandiswa kweCPE ine rabha. CPE ine rabha irabha yakagadzirwa nerabha ine mashandiro akanaka kwazvo, inodzivirira kupisa kuokisijeni neozone, uye inoderedza moto zvakanyanya.

Zvinhu zvinokanganisa tembiricha yekuora kweCPE pakupisa

Hunhu hweCPE pachayo hunoenderana nehuwandu hwechlorine hwayo. Kana huwandu hwechlorine hwakawandisa, zviri nyore kuora;

Zvine chekuita nekuchena. Kusabvisa zvakakwana zvinhu zvinotanga, macatalyst, maacid, mabhesi, nezvimwewo zvinowedzerwa panguva yekugadziriswa kwepolymer, kana kunyudzwa kwemvura panguva yekuchengetwa nekutakurwa, zvinogona kuderedza kugadzikana kwepolymer. Zvinhu izvi zvinogona kukonzera kukanganiswa kwemaion emamorekuru, uye CPE ine zvinhu zvishoma zvemamorekuru zvakaita seCl2 neHCl, izvo zvinogona kukurumidzisa kuora kwemafuta eresin;
