Muhupenyu hwedu, CPE nePVC zviri kushandiswa zvakanyanya. Chlorinated polyethylene ipurasitiki yakazara ine chitarisiko cheupfu huchena, haina chepfu uye haina kunaka, uye ine simba rakanaka rekudzivirira mamiriro ekunze, inodzivirira ozone, inodzivirira makemikari uye inodzivirira kukwegura. Inoshanda zvakanaka, ine simba rakanaka rekudzivirira mafuta, inodzivirira murazvo uye ine hunhu hwekupenda. Kusimba kwakanaka (kuchiri kuchinjika pa -30°C), inoenderana zvakanaka nezvimwe zvinhu zvepolymer, uye tembiricha yakanyanya kuora. Chlorinated polyethylene ipurasitiki yakagadzirwa nepolyethylene ine huwandu hwakanyanya (HDPE) kuburikidza nekuita chlorination substitution reaction. Zvichienderana nemaumbirwo akasiyana uye mashandisirwo, chlorinated polyethylene inogona kukamurwa muzvikamu zviviri: resin-type chlorinated polyethylene (CPE) uye elastomer-type chlorinated polyethylene (CM). Kuwedzera pakushandiswa chete, thermoplastic resins inogonawo kusanganiswa ne polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS uye kunyange polyurethane (PU). Muindasitiri yerabha, CPE inogona kushandiswa serabha yepamusoro-soro, uye inogona kushandiswawo nerabha re ethylene-propylene (EPR), rabha re butyl (IIR), rabha re nitrile (NBR), chlorosulfonated polyethylene (CSM), nezvimwewo. Mimwe misanganiswa yerabha inoshandiswa.
Mumakore ekuma1960, kambani yeGerman Hoechst yakatanga kubudirira kugadzira nekugadzira maindasitiri. Nyika yangu yakatanga kugadzira chlorinated polyethylene mukupera kwema1970. "Aqueous Phase Suspension Synthesis yeCPE Technology" yakatanga kugadzirwa zvinobudirira neAnhui Chemical Industry Research Institute, uye michina yekugadzira ye500-1000t/a ine zviyero zvakasiyana yakavakwa muWuhu, Anhui, Taicang, Jiangsu, uye Weifang, Shandong.
Kuramba kwemafuta kweCPE kuri pakati nepakati, pakati pazvo kupikisa kwemafuta eASTM Nhamba 1 nemafuta eASTM Nhamba 2 kwakanaka kwazvo, izvo zvakaenzana neNBR; kupikisa kwemafuta eASTM Nhamba 3 kwakanaka kwazvo, zviri nani pane CR, izvo zvakaenzana neCSM.
CPE ine chlorine, ine hunhu hwakanaka hwekudzivirira moto uye ine hunhu hwekupisa uye kudzivirira kudonha kwemvura. Inogona kusanganiswa ne antimony-based flame retardant, chlorinated paraffin, uye Al(OH)3 muchiyero chakakodzera kuti iwane chinhu chinodzivirira moto chine hunhu hwakanaka hwekudzivirira moto uye mutengo wakaderera.
CPE haina chepfu, haina simbi dzinorema uye PAHS, uye inosangana zvizere nezvinodiwa zvekuchengetedza nharaunda.
CPE ine simba rekuzadza rakawanda uye inogona kugadzirwa kuti ive zvigadzirwa zvinogutsa zvinodiwa zvakasiyana-siyana zvekushanda. CPE inogona kugadziriswa zvakanaka, viscosity yeMooney (ML121 1+4) iri pakati pe50-100, uye kune akawanda magiredhi ekusarudza kubva.
