Molao-motheo
Lilemong tsa morao tjena, ho bile le ngongoreho e ntseng e hola mabapi le likotsi tsa tikoloho le bophelo bo botle tse bakoang ke lintho tse thibelang malakabe tse thehiloeng ho halogen tse sebelisoang polasetiking. Ka lebaka leo, lintho tse thibelang malakabe tse seng tsa halogen li fumane botumo ka lebaka la litšobotsi tsa tsona tse sireletsehileng le tse tšoarellang haholoanyane.
Lintho tse thibelang malakabe tse se nang halogen li sebetsa ka ho sitisa lits'ebetso tsa ho tuka tse etsahalang ha polasetiki e pepesetsoa mollo.
1. Ba finyella sena ka ho kena-kenana ka matla le ka lik'hemik'hale le likhase tse tukang tse lokolloang nakong ea ho cha. E 'ngoe ea mekhoa e tloaelehileng ke ka ho thehoa ha lera la carbon le sireletsang holim'a polasetiki.
2. Ha di pepesetswa mocheso, di-halogen-free flame retardants di etsa karabelo ya dikhemikhale, e leng se ntshang metsi kapa dikgase tse ding tse sa tjheseng. Dikhase tsena di etsa mokoallo pakeng tsa polasetiki le lelakabe, ka hona di diehisa ho ata ha mollo.
3. Di-halogen-halogen-lame retardants di a bola mme di etsa lera le tsitsitseng la carbonized, le tsejwang e le char, le sebetsang e le tshitiso ya sebele, le thibelang ho lokollwa ha dikgase tse tukang.
4. Ho feta moo, di-halogen-lame retardants di ka ntsha dikhase tse tukang ka ho ionisa le ho tshwara di-free radical le dikarolo tse tukang. Karabelo ena e roba karabelo ya ketane ya ho tuka, e fokotsa matla a mollo haholo.
Ammonium polyphosphate ke sethibi sa malakabe se se nang phosphorus-nitrogen halogen. E na le ts'ebetso e phahameng ea sethibi sa malakabe polasetiking e nang le tšobotsi e seng chefo le ea tikoloho.
Tšebeliso ea polasetiki
Lipolasitiki tse thibelang malakabe tse kang FR PP, FR PE, FR PA, FR PET, FR PBT le tse ling li sebelisoa haholo indastering ea likoloi bakeng sa likamore tsa kahare tsa likoloi, joalo ka li-dashboard, liphanele tsa mamati, likarolo tsa litulo, liphanele tsa motlakase, literei tsa cable, liphanele tsa motlakase tse hanyetsang mollo, li-switchgear, liphanele tsa motlakase le liphaephe tsa khase tse tsamaisang metsi.
Tekanyetso e thibelang malakabe (UL94)
UL 94 ke tekanyetso ea ho cha ea polasetiki e lokollotsoeng ke Underwriters Laboratories (USA). Tekanyetso ena e arola polasetiki ho latela kamoo e chang ka litsela tse fapaneng le botenya ba likarolo ho tloha ho e thibelang malakabe ka tlase ho isa ho e thibelang malakabe ka lihlopha tse tšeletseng tse fapaneng.
