Daim ntawv thov:
1. Fyog retardant.Kev siv lub ntsiab ntawm antimony yog nws cov oxide antimony trioxide hauv kev tsim cov khoom siv refractory.Nws yuav luag ib txwm siv nrog halide nplaim taws retardants tshwj tsis yog rau cov nplaim hluav taws xob polymer uas muaj halogens.Kev tsim ntawm antimony halide los ntawm antimony trioxide tuaj yeem ua rau qeeb combustion, uas yog vim li cas rau nws cov nplaim hluav taws.
2. Alloy.Antimony tuaj yeem ua ke nrog cov hlau lead ua ntau yam alloys uas nws qhov hardness thiab mechanical zog tau txhim kho.Hauv ntau daim ntawv thov uas siv lead ua, antimony yog ntxiv rau ntau qhov sib txawv los ua cov hlau.Hauv cov roj ntsha lead-acid, cov khoom siv ntxiv hloov cov khoom siv hluav taws xob thiab txo qhov tsim ntawm hydrogen raws li cov khoom lag luam thaum tawm.
Daim ntawv pov thawj
Cov khoom tau pom zoo los ntawm FDA, REACH, ROSH, ISO thiab lwm yam ntawv pov thawj, raws li cov qauv hauv tebchaws.

FAQ:
Q: Koj puas yog tuam txhab lag luam lossis chaw tsim khoom?
A: Peb yog Hoobkas.
Q: Koj lub sijhawm xa khoom ntev npaum li cas?
A: Feem ntau nws yog 5-10 hnub yog tias cov khoom muaj nyob hauv Tshuag.los yog nws yog 15-20 hnub yog tias cov khoom tsis nyob hauv Tshuag, nws yog raws li kom muaj nuj nqis.
Q: Koj puas muab cov qauv?puas yog dawb los yog ntxiv?
A: Yog lawm, peb tuaj yeem muab cov qauv dawb tab sis tsis them tus nqi thauj khoom.
Q: Koj cov nqe lus them nqi yog dab tsi?
A: Them nyiaj<= 1000USD, 100% ua ntej.Kev them nyiaj>= 1000USD, 30% T / T ua ntej, tshuav nyiaj li cas ua ntej xa khoom.
