wb 9535Polyurethane nplaumrau cov chaw ua si lom zem, feem ntau yog tsim los ntawm PPG, MDI thiab chlorinated paraffin. Nws yog cov kua daj daj ntawm chav tsev kub.
Cov nqi no muab cov ntaub ntawv dav dav thiab tsis yog ib feem ntawm cov khoom specification
Daim ntawv thov
Thaum BQ9535 yog siv los khi cov khoom siv roj hmab, nws ua rau muaj kev xav tau siab ntawm daim ntawv thov kev paub ntawm tus neeg teb xov tooj thiab cov khoom siv roj hmab sib txuas. Cov txiaj ntsig kev sib raug zoo yog nyob ntawm qhov tsis yog ntawm cov nplaum nkaus xwb tab sis kuj ntawm cov khoom siv roj hmab, tus nqi ntawm cov nplaum siv, qhov kub thiab av noo thaum lub sij hawm thov, thiab txoj kev thov. Yog li ntawd, thov xa mus rau phau ntawv qhia no ua ntej siv cov khoom thiab ua ib qho kev sim ntsuas raws li qhov zoo sib xws ntawm -qhov chaw. Daim ntawv thov yuav tsum tsuas yog ua tom qab kev ntsuam xyuas txaus siab.
Thaum siv los ua ib qho -cov khoom siv yas nplaum, BQ9535 kho los ntawm kev cuam tshuam nrog cov dej noo hauv huab cua. Yog li ntawd, nws curing ceev yog heev nyob ntawm qhov kub thiab av noo ntawm huab cua. Ntawm 25℃thiab 50% txheeb ze cov av noo, nws nto- lub sij hawm ziab yog 8-12 teev, uas feem ntau tso cai rau cov tsho sab saum toj siv 12 teev tom qab txheej txheej ntawm cov roj hmab tau siv. Hauv qhov ntsuas kub thiab av noo qis (kub qis dua 20 degree, txheeb ze av noo qis dua 50%, lossis ob qho xwm txheej no tau ntsib), cov khoom siv hluav taws xob tuaj yeem raug ntxiv los kho qhov kho ceev.

Cov lus pom zoo saum toj no yog txwv rau cov khoom siv roj hmab uas tau xaiv los ntawm peb lub tuam txhab lub chaw kuaj. Cov khoom ntawm lub cev ntawm cov khoom siv yas, hom roj hmab thiab cov nplaum nplaum siv tau zoo heev. Cov neeg siv khoom tuaj yeem kho qhov kev tsim kho tshwj xeeb ntawm lawv tus kheej raws li qhov xwm txheej tshwj xeeb ua ntej kev tsim kho thiab ua qhov kev sim me me.
Cia
BQ9535 muaj cov tshuaj reactive thiab reacts yooj yim nrog noo noo, tsim insoluble urea tebchaw thiab tso carbon dioxide, uas yuav ua rau lub nruas bulging thiab nce viscosity. Yog li ntawd, thaum lub sij hawm cia, lub thawv yuav tsum tau qhuav thiab nruj nreem kaw.
BQ9535 yuav tsum muab cia rau hauv chav tsev kub (15 -25℃) nyob rau hauv ib lub qhov dej -ventilated chav tsev. Kev khaws cia ntawm qhov kub qis dhau (qis dua 0 degree) tuaj yeem ua rau crystallization, yog li yuav tsum tau saib xyuas kom tiv thaiv kom tsis txhob khov. Yog tias crystallization tshwm sim, nws yuav tsum tau yaj tam sim ntawd. Kev ziab hauv qhov cub cua kub uas muaj lub nruas ntawm 70-80℃yog pom zoo. Tsis txhob overheating hauv zos, raws li cov khoom decomposes thiab tsim roj ntawm qhov kub siab tshaj 230 degree. Kev ziab hauv qhov cub cua kub uas muaj lub nruas yog pom zoo. Tom qab ziab, cov ntsiab lus ntawm lub nruas yuav tsum sib tov kom huv si.
BQ9535 yuav tsum zam lub sijhawm ntev cia siab tshaj 50℃los tiv thaiv kev tsim cov khoom tsis sib xws thiab nce viscosity. Raws li qhov tsim nyog khaws cia, lub txee lub neej yog 9 lub hlis.
