Vagadziri veChlorinated Polyethylene CPE
Mupepeti wemugadziri wemishonga inodzivirira kukwegura achakuzivisai nhasi sumo yakakodzera nezvemugadziri we chlorinated polyethylene cpe. Chlorinated polyethylene (CPE) chigadzirwa chinoshandiswa mukugadzirwa kwemakemikari. Vanhu vazhinji havazivi nezve vinyl chloride chloride. Nzwisisai, chidimbu chechirungu che chlorinated polyethylene ndechekuti: CPE kana cm, chlorinated polyethylene (CPE) chinhu chakazara che polymer, chitarisiko chayo ihupfu chena, hachina chepfu uye hachina kunaka, ine simba rakanaka rekudzivirira mamiriro ekunze, inodzivirira ozone, inodzivirira makemikari uye inodzivirira kukwegura, inodzivirira mafuta zvakanaka, inodzivirira murazvo uye ine hunhu hwekudzivirira chiedza. Kusimba kwakanaka (kuchiri kuchinjika pa -30°C), inoenderana zvakanaka nezvimwe zvinhu zve polymer, tembiricha yakanyanya kuora, kuora kweHCl, HCl inogona kukonzera dechlorination reaction yeCPE.
Chlorinated polyethylene (HDPE) ipurasitiki yakagadzirwa nepolyethylene ine huwandu hwakanyanya (HDPE) kuburikidza nechlorination. Zvichienderana nemaumbirwo akasiyana uye mashandisirwo, polyethylene ine chlorinated inogona kukamurwa kuita resin chlorinated polyethylene (CPE) uye elastic chlorinated polyethylene (CM). Pamusoro pe thermoplastic resins dzinogona kushandiswa dzoga, dzinogonawo kusanganiswa ne polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin uye kunyange polyurethane (PU). Muindasitiri yerabha, CPE inogona kushandiswa serabha yepamusoro-soro, yepamusoro-soro, uye inogonawo kushandiswa ne ethylene-propylene rabha (EPR), butyl rabha (IIR), nitrile rabha (NBR), chlorosulfonated polyethylene (CSM). Shandisa pamwe chete nemamwe macompounds erabha.
Hunhu hweChlorinated Polyethylene
1) CPE haina chepfu, haina simbi dzinorema uye polycyclic aromatic hydrocarbons, uye inosangana zvizere nezvinodiwa zvekuchengetedza nharaunda.
2) CPE ine simba guru rekudzivirira mafuta, kunyanya mafuta eASTM1 neASTM2, akafanana neNBR; simba guru rekudzivirira mafuta eASTM3, zviri nani pane CR uye zvakafanana neCSM.
3) CPE ine simba rekuzadza rakawanda uye inogona kugadzirwa kuita zvigadzirwa zvinosangana nezvinodiwa zvakasiyana-siyana zvekushanda. CPE ine simba rekugadzira michina zvakanaka uye inowanikwa muMooney viscosity (ML1211+4) giredhi kubva pa50 kusvika ku100.
4) CPE irabha rakazara rine anti-oxidative oxidative oxidative oxidation, anti-ozone oxidation, acid nealkali resistance uye chemical properties.
5) CPE ine zvinhu zvine chlorine, ine hunhu hwakanaka hwekudzivirira moto, uye ine hunhu hwekudzivirira kudonha kwemvura. Iyo antimony-based flame retardant, chlorinated paraffin uye Al(OH)3 zvinoshandiswa pamwe chete zvakaenzana kuti zviwane chinhu chinodzivirira moto chine simba rakanaka rekudzivirira moto uye mutengo wakaderera.
