Abakhiqizi be-CPE be-Chlorinated Polyethylene
Umhleli womkhiqizi we-ejenti yokulwa nokuguga uzokwethula namuhla isingeniso esifanele mayelana nomkhiqizi we-cpe ene-chlorine e-cpe. I-polyethylene ene-chlorine (CPE) umkhiqizo osetshenziswa ekukhiqizweni kwamakhemikhali. Abantu abaningi abazi nge-vinyl chloride chloride. Qonda, isifinyezo sesiNgisi se-polyethylene ene-chlorine sithi: CPE noma cm, i-polyethylene ene-chlorine (CPE) iyinto ye-polymer egcwele, ukubukeka kwayo kuyimpuphu emhlophe, ayinabo ubuthi futhi ayinambitheki, inokumelana okuhle kwesimo sezulu, ukumelana ne-ozone, ukumelana namakhemikhali kanye nokumelana nokuguga, ukumelana kahle kwamafutha, ukubambezeleka komlilo kanye nezakhiwo zokuvikela ukukhanya. Ukuqina okuhle (kusaguquguquka ku--30°C), ukuhambisana okuhle nezinye izinto ze-polymer, izinga lokushisa eliphezulu lokubola, ukubola kwe-HCl, i-HCl kungenza ukusabela kwe-dechlorination kwe-CPE kusebenze.
I-polyethylene ene-chlorine (HDPE) iyinto eyenziwe nge-polymer eyenziwe nge-polyethylene ene-high-density (HDPE) ngokuyi-chlorination. Ngokwezakhiwo ezahlukene kanye nokusetshenziswa, i-polyethylene ene-chlorine ingahlukaniswa ibe yi-resin chlorine polyethylene (CPE) kanye ne-elastic chlorine polyethylene (CM). Ngaphezu kwama-thermoplastic resins angasetshenziswa wodwa, angaxutshwa ne-polyvinyl chloride (PVC), i-polyethylene (PE), i-polypropylene (PP), i-polystyrene (PS), i-ABS resin kanye ne-polyurethane (PU). Embonini yerabha, i-CPE ingasetshenziswa njengerabha ekhethekile esebenza kahle kakhulu, esezingeni eliphezulu, futhi ingasetshenziswa nerabha ye-ethylene-propylene (EPR), irabha ye-butyl (IIR), irabha ye-nitrile (NBR), i-chlorosulfonated polyethylene (CSM) Sebenzisa nezinye izinhlanganisela zerabha.
Izakhiwo ze-Chlorinated Polyethylene
1) I-CPE ayinabo ubuthi, ayinazo izinsimbi ezisindayo nama-polycyclic aromatic hydrocarbons, futhi ihlangabezana ngokugcwele nezidingo zokuvikela imvelo.
2) I-CPE inokumelana okuhle kakhulu kwamafutha, ikakhulukazi amafutha e-ASTM1 kanye ne-ASTM2, afana ne-NBR; ukumelana okuhle kakhulu kwamafutha e-ASTM3, angcono kune-CR futhi afana ne-CSM.
3) I-CPE inokusebenza okuphezulu kokugcwalisa futhi ingenziwa imikhiqizo ehlangabezana nezidingo zokusebenza ezahlukahlukene. I-CPE inokusebenza okuhle kakhulu futhi itholakala kumazinga e-Mooney viscosity (ML1211+4) asukela ku-50 kuya ku-100.
4) I-CPE iyirabha egcwele kahle kakhulu elwa nokuguga okulwa nokuguga, ukuguga okulwa ne-ozone, ukumelana ne-asidi ne-alkali kanye nezakhiwo zamakhemikhali.
5) I-CPE iqukethe izakhi ze-chlorine, inezakhiwo ezinhle kakhulu zokuvimbela ilangabi, futhi inezici zokuvimbela ukuvuza. I-antimony-based flame retardant, i-chlorine paraffin kanye ne-Al(OH)3 zisetshenziswa ndawonye ngesilinganiso esifanele ukuthola into evimbela ilangabi esebenza kahle futhi engabizi kakhulu.
