Muhupenyu hwedu, CPE nePVC zviri kuwedzera uye zvakanyanya kushandiswa. Chlorinated polyethylene chinhu chakazara chepolymer chitarisiko chehupfu chena, chisiri chepfu uye chisingarapike, uye chine kunaka kwemamiriro ekunze, kuramba kwe ozone, kuramba kwemakemikari uye kuramba kuchembera. Kuita, neakanaka mafuta kuramba, murazvo retardancy uye coloring zvivakwa. Kusimba kwakanaka (kuchiri kuchinjika pa -30 ° C), kuenderana zvakanaka nezvimwe zvinhu zvepolymer, uye tembiricha yekuora yakanyanya. Chlorinated polyethylene chinhu chepolymer chakagadzirwa kubva pakakwirira-density polyethylene (HDPE) kuburikidza neklorination substitution reaction. Zvinoenderana nezvimiro uye mashandisirwo akasiyana, chlorinated polyethylene inogona kukamurwa kuita mapoka maviri: resin-mhando chlorinated polyethylene (CPE) uye elastomer-mhando chlorinated polyethylene (CM). Pamusoro pekushandiswa chete, thermoplastic resins inogona zvakare kusanganiswa ne polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS uye kunyange polyurethane (PU). Muindasitiri yerabha, CPE inogona kushandiswa seyepamusoro-kuita, yepamusoro-mhando yakakosha rubber, uye inogona zvakare kushandiswa ne ethylene-propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene ( CSM), etc. Mamwe masanganiswa erubha anoshandiswa.
Mumakore ekuma1960, kambani yeGerman Hoechst yakatanga kubudirira kugadzira uye kuona kugadzirwa kwemaindasitiri. nyika yangu yakatanga kugadzira chlorinated polyethylene mukupera kwema1970. Iyo "Aqueous Phase Suspension Synthesis yeCPE Technology" yakatanga kubudirira kugadzirwa neAnhui Chemical Industry Research Institute, uye zvigadzirwa zvekugadzira zve500-1000t/a zvine zviyero zvakasiyana zvakavakwa muWuhu, Anhui, Taicang, Jiangsu, uye Weifang, Shandong. .
Kurwisana kwemafuta eCPE kuvhareji, pakati peiyo kushorwa kweASTM No. 1 mafuta uye ASTM No. 2 mafuta yakaisvonaka, iyo yakaenzana neNBR; kupikisa ASTM No. 3 oiri yakanakisa, iri nani pane CR, iyo yakaenzana neCSM.
CPE ine chlorine, ine yakanakisa murazvo retardant zvivakwa uye ine hunhu hwekupisa uye anti-kudonha. Inogona kusanganiswa neantimony-based flame retardant, chlorinated parafini, uye Al(OH) 3 muchiyero chakakodzera kuti uwane zvinhu zvinodzora murazvo zvine hunyanzvi hwekudzoreredza moto uye mutengo wakaderera.
CPE haina chepfu, haina simbi inorema uye PAHS, uye inosangana zvizere nekuchengetedzwa kwezvakatipoteredza zvinodiwa.
CPE ine yakakwira kuzadza kuita uye inogona kugadzirwa kuita zvigadzirwa zvinosangana nemhando dzakasiyana dzekuita zvinodiwa. CPE ine yakanaka processability, Mooney viscosity (ML121 1 + 4) iri pakati pe50-100, uye kune akawanda mamakisi ekusarudza kubva.
