Yuav tsum nco ntsoov tias thaum siv cov tshuaj ammonium polyphosphate uas yaj tau hauv dej, yuav tsum siv rau hauv qhov ntau thiab tsawg thiab txoj kev kom tsis txhob muaj kev cuam tshuam tsis zoo rau cov qoob loo thiab ib puag ncig. Thaum siv, yuav tsum ua raws li cov txheej txheem kev nyab xeeb.
Cov dej-soluble ammonium polyphosphate
Cov dej-soluble ammonium polyphosphate kuj tseem siv dav hauv thaj chaw ntawm cov nplaim taws retardants.
Cov ammonium polyphosphate uas yaj tau hauv dej kuj siv dav hauv kev ua cov tshuaj tiv thaiv hluav taws. Nws cov yam ntxwv tseem ceeb thiab kev siv yog raws li nram no:
Kev ua haujlwm hluav taws kub zoo:
Cov ammonium polyphosphate uas yaj tau hauv dej tuaj yeem txo qhov kev ua haujlwm ntawm cov khoom siv thiab muaj cov nyhuv zoo tiv thaiv hluav taws. Nws tuaj yeem tiv thaiv kev tso cua sov thiab nplaim taws kis thaum lub sijhawm hlawv, txo qhov tshwm sim ntawm hluav taws.
Daim ntawv thov ntau thaj chaw:
Ammonium polyphosphate uas yaj tau hauv dej yog siv dav hauv kev hloov kho cov ntaub ntawv xws li textiles, ntoo, thiab ntawv uas tiv taus hluav taws. Nws tuaj yeem sib xyaw nrog cov substrate los ntawm kev sib tov, txheej lossis ntxiv kom muaj cov nyhuv tiv taus hluav taws ntev.
Kev ruaj khov siab
Cov dej-soluble ammonium polyphosphate kuj muaj kev ruaj khov zoo ntawm qhov kub siab, nws tseem tuaj yeem tswj tau cov nplaim taws retardant nyhuv ntawm qhov kub siab dua, thiab nws tsis yooj yim rau decompose lossis volatilize.
Kev tiv thaiv ib puag ncig
Cov ammonium polyphosphate uas yaj tau hauv dej yog cov nplaim taws uas tsis ua rau ib puag ncig puas tsuaj, nws cov khoom lwj yuav tsis tsim cov tshuaj lom, thiab pab tiv thaiv kev tsim cov pa luam yeeb thiab txo qhov kev puas tsuaj ntawm hluav taws rau tib neeg kev noj qab haus huv thiab ib puag ncig.
Yuav tsum nco ntsoov tias kev siv thiab qhov sib piv ntawm cov ammonium polyphosphate uas yaj hauv dej yuav txawv nyob rau hauv cov ntaub ntawv sib txawv thiab cov xwm txheej ntawm kev siv. Thaum siv, yuav tsum xaiv hom tshuaj tua hluav taws zoo tshaj plaws thiab txoj kev siv raws li qhov xwm txheej tshwj xeeb, thiab yuav tsum ua raws li cov txheej txheem kev nyab xeeb kom ntseeg tau tias cov nyhuv tua hluav taws thiab kev nyab xeeb ntawm kev siv.
Daim Ntawv Thov
1. Cov kua dej siv rau kev kho mob retardant. Txhawm rau npaj 20-25% PN nplaim taws retardant, siv nkaus xwb lossis ua ke nrog lwm cov ntaub ntawv hauv kev kho hluav taws rau cov ntaub, ntawv, fibers thiab ntoo, thiab lwm yam. Txhawm rau thov los ntawm autoclave, immersion lossis los ntawm kev tsuag ob qho tib si ok. Yog tias kev kho mob tshwj xeeb, nws tuaj yeem siv los npaj cov kua hluav taws kub-concentration siab txog 50% kom ua tau raws li qhov xav tau nplaim taws ntawm kev tsim khoom tshwj xeeb.
2. Nws kuj siv tau ua cov tshuaj tua hluav taws hauv cov tshuaj tua hluav taws uas siv dej thiab cov tshuaj pleev ntoo,
3. Nws kuj siv ua cov chiv binary compound siab, cov chiv qeeb tso tawm.
Cov mis rau kev siv ntoo
Kauj Ruam 1:Siv TF-303 los npaj cov tshuaj nrog ib feem loj ntawm 10% ~ 20%.
Kauj Ruam 2:Kev ntub ntoo
Kauj Ruam 3:Kev ziab ntoo los yog kev ziab cua ntuj
Qhov kub thiab txias kom qhuav: tsawg dua 60 degrees, tshaj 80 degrees yuav tsim cov ntxhiab tsw ammonia
