Qhov zoo ntawm txhuas hydroxide nplaim retardant
Txawm hais tias bromine raws cov nplaim hluav taws retardants hauv cov nplaim hluavtaws retardans, thiab kev ua tsis zoo thiab siv cov nplaim taws uas tsis tshua muaj kev txhawb nqa thiab kev pab ntau ntxiv.
Ultra Nplua Aluminiumide muaj lub cev thiab tshuaj lom neeg nyob rau hauv chav tsev kub, thiab tsis tsim muaj kuab paug ob zaug thaum kev sib txuas. Nws muaj siab dawb huv thiab cov cim chromatic chromatic. Thiab nano aluminium hydroxide tsis tuaj yeem txhim kho cov tshuaj oxygen tsawg ntawm cov nplaim hluav taws xob, tab sis kuj tseem ua haujlwm xau, arc thiab hnav. Tsis tas li ntawd, cov teeb meem sib xyaw ntawm txhuas hydroxide thiab lwm yam nplaim taws retardants yog qhov zoo tshaj plaws, ua rau nws muaj inorganic nplaim retardant nrog cov kev cia siab.
Cov nplaim taws retardant mechanism ntawm txhuas hydroxide
Cov nplaim taws retardant mechanism ntawm txhuas hydroxide yog qhov sib txawv, suav nrog cov cuab yeej hauv qab no ua haujlwm ua ke:
1) Cov tshuaj tiv thaiv oveothermic
Raws li peb tau hais saum toj no, Aluminium hydroxide reacts nrog cov cua sov kom ua cov tshuaj txhuas txhuas txhuas thiab dej. Qhov tshuaj tiv thaiv no yog endothermic cov tshuaj tiv thaiv, thiab cov kev tawm tsam yog:
Thaum lub sij hawm tus txheej txheem no, tsis tsuas yog nqus tau thaum tshav kub kub thiab ncua kev sib txuas ntawm cov tshuaj tiv thaiv cov tshuaj tiv thaiv roj thiab oxygen, thiab koom nrog theem kev tawm tsam.
2) dilution cuam tshuam
Ntxiv nrog rau cov dej vapor tau hais hauv 1), uas tuaj yeem siv roj av thiab cov pa roj polymer, ua rau muaj cov pa roj polymer,
3) Cov nyhuv pab them nqi
Aluminium oxide thiab lwm tus carbides tsim los ntawm cov tshuaj tiv thaiv cov nplaim hluav taws xob retardant barrier, suppressing kev sib kis ntawm nplaim taws.
4) Cov txheej txheem carbonation
Nplaim taws retardants tsim muaj zog cov tshuaj muaj zog nyob rau hauv cov kev sib txuas ntawm cov nyom, yog li tiv thaiv kev sib tiv thaiv cov nplaim taws.
