1, yogob-txheej txheem dej-raws li xim, uas tsis muaj benzene cov kuab tshuaj lom thiab tsis zoo, thiab yog ib puag ncig zoo, nyab xeeb thiab noj qab nyob zoo;
2, nyob rau hauv cov ntaub ntawv ntawm hluav taws kub, ib tug tsis-combustible spongy nthuav carbon txheej yog tsim, uas plays lub luag hauj lwm ntawm tshav kub rwb thaiv tsev, oxygen rwb thaiv tsev, thiab nplaim hluav taws rwb thaiv tsev, thiab muaj peev xwm tiv thaiv lub substrate los ntawm ignited;
3, Lub thickness ntawm txheej tuaj yeem hloov khoraws li qhov yuav tsum tau muaj ntawm nplaim retardant.Qhov nthuav dav ntawm cov pa roj carbon txheej tuaj yeem ncav cuag ntau dua 100 zaug, thiab cov txheej nyias nyias tuaj yeem siv tau kom tau txais cov nplaim hluav taws kub zoo;
4, Cov xim zaj duab xis muaj qee qhov kev nruj tom qab ziab, thiab tsis tuaj yeem siv rau ntawm cov substrates uas muag heev thiab yuav tsum tau khoov ntau zaus.
