O le a le Suiga Polyethylene?

O ituaiga eseese o le polyethylene e masani lava ona aofia ai polyethylene chlorinated, polyethylene chlorosulfonated, polyethylene feso'ota'i ma fa'afefiloi fa'afefiloi.

Polyethylene chlorinated:

O se chloride fa'afuase'i e maua e ala i le sui vaega o le hydrogen atoms i polyethylene i le chlorine. Chlorination o loʻo faʻatinoina i lalo o le amataga o le malamalama poʻo le peroxyide, ma e masani ona gaosia e ala ile vai faʻamalolo ile alamanuia. Ona o le eseesega i le molecular mamafa ma le tufatufaina, lala lala, chlorination tikeri ina ua uma chlorination, chlorine atom tufatufaina ma crystallinity totoe o mata polyethylene, chlorinated polyethylene mai rubbery i palasitika malo e mafai ona maua. O le faʻaoga autu o le faʻaogaina o le polyvinyl chloride e faʻaleleia ai le aʻafiaga o le polyvinyl chloride. Chlorinated polyethylene lava ia e mafai foi ona faʻaaogaina e fai ma mea faʻapipiʻi eletise ma mea eleele.

Chlorosulfonated polyethylene:

Pe a tali le polyethylene ma le chlorine o loʻo i ai le sulfur dioxide, o se vaega o le hydrogen atoms i totonu o le mole e suia i le chlorine ma se vaega itiiti o le sulfonyl chloride vaega e maua ai le polyethylene chlorosulfonated. O le auala autu tau alamanuia o le faʻamalologa metotia. Chlorosulfonated polyethylene e teteʻe i le ozone, vailaʻau faʻamaʻi, suauu, vevela, malamalama, abrasion ma le malosi. O se elastomer ma mea lelei atoatoa ma e mafai ona faʻaaogaina e fai ai vaega meafaigaluega e faʻafesoʻotaʻi ai meaʻai.

XLPE:

Fa'aaogā auala fa'avevela (X-ray, uila eletise po'o le ultraviolet irradiation, ma isi) po'o le vaila'au (peroxide po'o le silicone cross-linking) e fai ai le polyethylene laina i totonu o feso'ota'iga po'o le tele o polyethylene fa'afeso'ota'i. Faatasi ai ma i latou, o le silicone cross-linking method o loʻo i ai se faʻagasologa faigofie, maualalo tau faʻaogaina, ma o le faʻaogaina ma le faʻaogaina o fesoʻotaʻiga e mafai ona faia i laasaga, o lea e fetaui lelei ai le faʻafefeteina ma le tui tui. O le vevela o le vevela, faʻalavelave faʻafefe o le siosiomaga ma mea faʻainisinia o le polyethylene fesoʻotaʻi faʻasolosolo e matua faʻaleleia pe a faʻatusatusa i le polyethylene, ma e talafeagai mo paipa tetele, uaea ma uaea, ma oloa rotomolding.

Fa'afefiloi suiga ole polyethylene:

A maeʻa ona faʻafefiloi le polyethylene maualalo maualalo ma le polyethylene maualalo maualalo, e mafai ona faʻaaogaina e faʻagasolo ata tifaga ma isi oloa, ma e sili atu le faʻatinoga o oloa nai lo le polyethylene maualalo maualalo. Polyethylene ma le ethylene propylene pa'u e mafai ona fa'afefiloi e maua ai le tele o ituaiga vevela elastomers
