Ordinary ABS yas ntawv yog cov khoom siv hluav taws xob. Txhawm rau kom ua tiav cov nplaim hluav taws kub, qhov tseem ceeb tshaj plaws yog kom muaj cov nplaim hluav taws kub hnyiab rau hauv ABS resin los ntawm kev hloov kho, tso cai rau cov khoom siv los tiv thaiv lossis ncua kev sib tsoo thaum raug hluav taws.
Cov kev daws teeb meem tseem ceeb tam sim no tuaj yeem muab faib ua ob pawg, txhua tus muaj nws tus yam ntxwv.
Brominated Nplaim Retardant Systems: Sawv cev los ntawm decabromodiphenyl ethane (DBDPE), cov kab ke no feem ntau siv nrog antimony trioxide (Sb₂O₃). Qhov no yog cov nplaim taws zoo heev thiab ua haujlwm tau zoo-kev sib xyaw ua ke. Ntxiv chlorinated polyethylene (CPE) rau hauv lub cev tsis yog tsuas yog ua haujlwm raws li cov nplaim hluav taws kub nyhiab, tab sis kuj tseem txhim kho cov khoom siv lub zog thiab kev tawm tsam cov pa luam yeeb, them nyiaj rau qhov tsis zoo ntawm cov tawv nqaij hauv cov nplaim taws ib txwm muaj - retardant ABS. Nrog rau txoj hauv kev no, cov khoom siv ABS feem ntau tuaj yeem ua tiav aKev ntsuas UL94 V-0(cov nplaim hluav taws kub siab tshaj plaws hauv kev lag luam rau kev ntsuas hluav taws xob ntsug), ua tau raws li qhov yuav tsum tau ua rau feem ntau cov khoom siv hluav taws xob thiab hluav taws xob.
Intumescent Nplaim Retardant Systems: Cov tshuab no feem ntau yog tsim los ntawm phosphorus thiab nitrogen, xws li ammonium polyphosphate (APP) lossis melamine cyanurate (MCA). Thaum rhuab, cov nplaim hluav taws kub hnyiab sai sai ua rau tuab, nthuav dav charred npuas txheej ntawm cov khoom siv saum npoo. Qhov no "cov ntaub thaiv npog" zoo insulates tiv thaiv tshav kub thiab oxygen, thaum tiv thaiv molten drips, yog li txwv tsis pub kis hluav taws. Kev sib txuas cov nplaim hluav taws xob zoo li no nrog nano- av nplaum tuaj yeem tsim cov txiaj ntsig zoo, txo cov nplaim hluav taws xob xav tau thaum txhim kho cov khoom siv ua haujlwm thiab kev ruaj ntseg.
Yog tias lub hom phiaj tseem ceeb yog cov nplaim hluav taws kub siab -kev ua haujlwm tsis zoo thiab cov khoom siv hluav taws xob ruaj khov, thiab cov kev xav tau ib puag ncig tsis nruj heev, cov nplaim hluav taws xob brominated yog qhov kev xaiv paub tab thiab txhim khu kev qha. Yog hais tias qhov tseem ceeb tshaj yog muab tso rau ib puag ncig tus phooj ywg, tsis muaj pa luam yeeb, thiab tsis muaj toxicity, thiab ib tug tej yam kev nce nyob rau hauv tus nqi thiab kev ua tau zoo hloov tau, ces lub intumescent nplaim retardant system sawv cev rau yav tom ntej kev taw qhia.
Nplaim taws- cov ntaub ntawv ABS retardant feem ntau tsis ua tiav los ntawm kev sib xyaw yooj yim. Cov txheej txheem yuav tsum tau siv cov cuab yeej tshaj lij xws li ntxaib - ntsia hlau extruder rau yaj compounding thiab pelletizing, kom ntseeg tau tias cov nplaim hluav taws kub hnyiab tau zoo sib xws hauv ABS. Yog li ntawd, ncaj qha mus yuav cov nplaim hluav taws xob tshaj lij- retardant ABS hloov cov yas pellets thiab tom qab ntawd siv kev txhaj tshuaj molding lossis extrusion rau kev sib sau yog txoj hauv kev ncaj qha thiab txhim khu kev qha kom ntseeg tau cov khoom zoo.
Zuag qhia tag nrho, ABS nplaim taws- thev naus laus zis thev naus laus zis tau txav mus rau kev ua tus phooj ywg zoo dua qub, ua haujlwm tau zoo, thiab muaj ntau yam haujlwm. Qhov no suav nrog kev tsim cov nplaim hluav taws sib txuas uas yog halogen-dawb, qis- lom, muaj txiaj ntsig zoo, thiab muaj peev xwm ua ke nrog cov thev naus laus zis xws li nanomaterials.
