Vim li cas hmoov cov hmoov nplej retardants muaj cov teebmeem sib txawv? Txhua tus neeg hauv cov nplaim taws retardant kev lag luam paub.
Cov txheej txheem kom ua tiav cov nplaim rov qab yog kom tusyees teeb meem retardants rau hauv cov khoom lag luam thaum lub sijhawm noj. Cov teeb meem uas ib txwm muaj ntawm cov neeg tsim khoom lag luam feem ntau yog cov nplaim ci retardant tsis yog pom thiab nplaim retardant yog qhov tsis xwm yeem. Nyob rau hauv tib qho khoom, qee qhov nruab nrab hauv qab retardants muaj cov nplaim taws pom tseeb, thaum lwm tus muaj cov nplaim tsis zoo retardant cuam tshuam thiab tsis yog nplaim retardant txhua. Cov nplaim taws retardant nyhuv ntawm tib nplaim retardant yog qhov zoo ntawm cov board tau noj los ntawm ib lub tshuab, tab sis tsis zoo ntawm lwm lub tshuab. Cov nplaim retardant ua tau zoo ntawm tib lub tshuab thiab cov tuam ntxhab sib txawv txawv heev.
1, Vim yog tib neeg cov ntsiab lus, tus nqi ntawm cov nplaim hluav taws tau ntxiv rau lub rooj tsavxwm extruded yog me me, feem ntau tsawg dua 10%. Txhawm rau kom muaj tusyees faib cov nplaim taws retardant hauv cov khoom, sib xyaw yog qhov tseem ceeb hauv zos. Txhawm rau kom ua tiav qhov nruab nrab ntawm kwv yees li 5 grams nplaim retardant ib 100 grams cov khoom, nws yog qhov xav tau ntau tus neeg lossis cov khoom sib xyaw tshwj xeeb yog xav tau kom tsis txhob sib xyaw. Cov tuam txhab feem ntau tau txau cov nplaim taws retardant ntawm cov ntaub ntawv sau thiab pub nws ncaj qha rau hauv feeder. Txawm hais tias tus pub mis yog nruab nrog nws tus kheej sib xyaw ntaus ntawv, nws tsuas yog ua ib qho me me hauv lub sijhawm luv luv, thiab tom qab ntawd extrude nws. Lub phab ntsa sab nraud ntawm Fangshan yog them nrog Ntawv Nyiaj Pob Zeb Wor Board los ua cov nplaim hluav taws xob ib nrab.
2, vim tias cov khoom siv ntawm cov khoom siv sib txawv muaj cov txheej txheem sib txawv, kev sib txawv, ua rau cov khoom lag luam sib txawv, thiab cov khoom lag luam sib txawv hauv lub hau ntswj. Cov nplaim hluavtaws retardants feem ntau yog suav nrog Hexabromocane, thiab lawv cov synthesis kub yog qis dua uas muaj kev kub ntxhov ntawm cov laug cam extruded. Lub cua sov kub ntawm cov laug cam zoo li yog txaus los ua rau feem ntau ntawm cov nplaim taws retardant synthesis tsis muaj peev xwm. Yog li ntawd, peb feem ntau siv cov lus kub yaj ua qhov tshwj xeeb rau XPS extruded cov laug cam, ntau dua li qhov kub kub. Cov neeg tau noj tau tau pom tias cov tuam ntxhab ntseeg tias thaum lub suab kub yaj tau hloov kho ntawm 175 {190 Qhov kev ua kub no yog qhov sib txawv ntawm cov txheej txheem ntsuas kub muab los ntawm cov cuab yeej siv hluav taws xob feem ntau yog ua raws cov hws ntawm cov khoom kub ntawm cov khoom siv tshiab tshiab ntawm cov khoom siv tshiab. Hauv kev siv tau, 90% ntawm XPS extruded daim hlau tau noj nrog rov ua dua ps tej batcled nruab nrab ntawm rov ua dua ps thiab cov ntaub ntawv tshiab yog 20-30 degree. Ntsia thawv txiav cov ntaub ntawv ua rau muaj ntau npaum li cas ntawm shear kub, uas kis tau rau cov ntaub ntawv thiab extruded. Lub shear tshav kub ntawm cov cuab yeej accumulates siab dua thiab siab dua. Yog tias cov cua txias kub thiab dej txias tsis tau nres rau cov mob thaum lub sijhawm siv ntev, nws tseem yuav ua rau muaj hluav taws xob tsis ua haujlwm ntawm cov nplaim hluav taws xob.
