Chlorinated polyethylene (CPE) matou te masani ai

I lo tatou olaga, CPE ma PVC e sili atu ma sili atu ona faʻaaogaina. Chlorinated polyethylene o se mea polymer tumu ma foliga paʻepaʻe paʻepaʻe, e le oona ma le tofo, ma e sili ona lelei le tetee i le tau, osone tetee, kemikolo tetee ma le matua tetee. Fa'atinoga, fa'atasi ai ma le suau'u lelei, fa'afefe mu ma mea fa'alanu. Malosi lelei (fa'alelei pea i le -30°C), fetaui lelei ma isi mea polymer, ma maualuga le vevela vevela. O le polyethylene chlorinated o se mea polymer e faia mai le maualuga-density polyethylene (HDPE) e ala i le faʻaogaina o le chlorination. E tusa ai ma fausaga eseese ma faʻaoga, e mafai ona vaevaeina le polyethylene chlorinated i ni vaega se lua: resin-type chlorinated polyethylene (CPE) ma le elastomer-type chlorinated polyethylene (CM). I le faaopoopo atu i le faʻaaogaina na o ia, e mafai foi ona faʻafefiloi resini vevela ma le polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS ma e oʻo lava i le polyurethane (PU). I totonu o pisinisi paʻu, e mafai ona faʻaaogaina le CPE o se paʻu faʻapitoa maualuga, maualuga, ma e mafai foi ona faʻaaogaina i le ethylene-propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene ( CSM), ma isi. O lo'o fa'aogaina isi paluga pa'u.
I le 1960s, o le kamupani Siamani Hoechst muamua na faʻatupuina ma iloa le gaosiga o fale gaosi oloa. na amata fausia e loʻu atunuu le polyethylene chlorinated i le faaiuga o le 1970s. O le "Aqueous Phase Suspension Synthesis of CPE Technology" na muamua atiina ae ma le manuia e le Anhui Chemical Industry Research Institute, ma masini gaosiga o 500-1000t / a ma fua eseese ua fausia i Wuhu, Anhui, Taicang, Jiangsu, ma Weifang, Shandong .
O le suauʻu teteʻe o le CPE o le averesi, e aofia ai le tetee atu i le ASTM Numera 1 suauu ma le ASTM Numera 2 suauu e sili ona lelei, lea e tutusa ma le NBR; o le tetee i le ASTM Numera 3 suauu e sili ona lelei, sili atu nai lo CR, lea e tutusa ma le CSM.
O le CPE o loʻo i ai le chlorine, o loʻo i ai mea e sili ona lelei e faʻafefe ai le afi ma e iai uiga o le mu ma le faʻafefe. E mafai ona tu'ufa'atasia ma le antimony-based flame retardant, chlorinated paraffin, ma le Al(OH)3 i se fua faatatau talafeagai e maua ai se mea e fa'afefe ai le mumu ma le lelei o le fa'atinoga o le mu ma le tau maualalo.
O le CPE e le o'ona, e le o iai ni metala mamafa ma PAHS, ma fa'amalieina atoatoa le puipuiga o le siosiomaga.
O le CPE e maualuga le faʻatumuina o faʻatinoga ma e mafai ona faia i oloa e fetaui ma manaʻoga faʻatinoga eseese. CPE e lelei processability, Mooney viscosity (ML121 1 + 4) i le va o 50-100, ma e tele togi e filifili mai.
