HCPE (Pa'u fa'aoloina)
HCPE (Pa'u fa'aoloina)
pa'epa'e malamalama ni vaega laiti. Talu ai o le mole mole fausaga e le o iai ni fusi faʻalua ma o le chlorine atoms e tufatufaina faʻafuaseʻi, o loʻo i ai le lelei o le tau, osone resistance, vevela matua tetee, afi mumu, vailaʻau ma le suauu. Fa'aaogaina e sui ai le pa'u chlorinated i le fa'apipi'i gaosiga.
E mafai foi ona faʻaaogaina le HCPE e pei o ni mea faʻapipiʻi, vali, faʻamalama afi, ma faʻaoga vaitusi maualuga, lea e mafai ona faʻaleleia atili ai le pipii, faʻafefeteina, faʻamaʻi afi, ma le abrasion teteʻe. Faʻaaogaina e pei o vali mata, o le aʻafiaga autu o le anti-corrosion o le chloride ion, o lea pe a olo i le taumafanafana, pe a sili atu le vevela o le vevela i le 60 ° C, e tatau ona mafaufau i le malulu pe faʻapipiʻi ese le fofo e faʻaopoopo i le tane maeʻa, aua i le 56 ° C, chloride ion precipitates , O le anti-corrosion faatinoga o vali ua faaitiitia, ma le mamafa anti-corrosion vali e faaaoga.

| mea e lefulefu | 0.4 | 0.4 |
Fa'aaoga nai lo le pa'u chlorinated e fai ai mea fa'apipi'i. E mafai foʻi ona faʻaaogaina e fai ma sui mo mea faʻapipiʻi, inks maualuga ma isi oloa, lea e mafai ona faʻaleleia atili ai le faʻapipiʻiina, faʻafefeteina, mumu mumu, ma vaega faʻafefete. Teu i totonu o se faleteuoloa malulu, malulu ma mago, mamao ese mai le susu.
Ona o le fausaga mole masani, saturation, polarity maualalo ma lelei mautu kemikolo o pa'u chlorinated, eseese coatings anti-corrosion saunia faatasi ai ma uiga o le vave mago o le ufiufi ata tifaga, pipii lelei, tetee atu i ala o faasalalauga kemikolo ma sili ona tetee atu i le susū ulu. .
Highly chlorinated polyethylene HCPE e sili ona lelei le atmospheric aging resistance and chemical medium resistance, e faigofie ona solu i aromatic hydrocarbons, esters, ketones ma isi solvents organic, ma e lelei le fetaui ma le tele o pigments inorganic ma organic faʻaaogaina i coatings. E masani lava, e fetaui lelei mo le faʻamavaeina i totonu ole 40% vaifofo resin faʻamautu mo le valiina.
