1. Txuas lub hwj huam hloov, qhov taw qhia lub zog tsis tau taws
Qhib sab npog sab hauv cov ceg hauv lub puab tsaig thiab xyuas seb lub tshuab fuse tseem ceeb yog tshuab.
2. Cov foaming yog tawg thiab xim yog tsaus
1) Txheeb xyuas cov khoom siv dawb lub sab lim tshuaj ntsuam, lub qhov dawb khoom siv ntawm lub rab phom nozzle, seb lub qhov oblique thaiv li cas, seb lub tshuab lim hauv qab ntawm lub twj tso kua mis dawb yog thaiv, thiab ntxuav nws yog tias muaj.
2) PAppropriately ua rau kub lossis siab ntawm cov khoom dawb. (Nws tuaj yeem muab sau ua qhov yoojyim xws li: cov khoom siv dub ntau dhau)
3) Lub xeev ejection tsis zoo:
Cov laj thawj rau qhov kub thiab txias: Yog tias qhov kub siab dhau lawm, tus neeg sawv cev foaming hauv lub polyol yuav vaporize, uas yuav ua rau cov ntaub ntawv pov thawj kom muaj qhov npliag, ua rau cov ntaub ntawv ya mus ntau dhau; yog tias qhov ntsuas kub tsawg dhau, nws yuav tsim cov teeb meem wispy. Qhov ob hom khoom nyoos yog tsis sib tov sib xyaw, ua rau muaj cov khoom pov tseg, uas ua rau lub nrig tsis zoo thiab qhov tsis ua haujlwm tsis zoo ntawm cov khoom.
Ua rau muaj qhov siab: Lub siab dhau ntawm lub tshuab polyurethane txau tshuab yuav ua rau muaj kev tawg loj thiab thau rov qab los ntawm cov khoom siv txau lossis txau tawg; qhov siab dhau yuav ua rau tsis sib xyaw ntawm cov khoom nyoos.
4. Lub A lossis B twj tso kua mis dhia nrawm, thiab lub txim tsis zoo tso tawm txo lossis
1) Tam sim ntawd nres tshuab thiab xyuas seb puas yog cov khoom dub lossis dawb cov khoom siv hauv khoob. Yog li, hloov cov ntaub ntawv thiab muab cov pa hauv cov yeeb nkab pub rau kom khov. Txwv tsis pub, cov khoom siv khoob yeeb nkab yuav yooj yim hlawv cov cua sov!
2) Kuaj xyuas seb lub taub hau tso kua mis thiab cua ntsia hlau ua ke tau xoob.
5. Lub tshuab txau ntawm polyurethane foaming tshuab dawb thiab muag muag thiab kev ua kom deb
1) Kuaj xyuas cov khoom dub sab lim tshuaj ntsuam, rab phom nozzle lub qhov taub, qhov oblique thaiv, yog tias muaj, ntxuav nws kom huv.
2) Tsim nyog nce qhov kub thiab siab ntawm cov khoom dub. Thaum cov pa cua nyob ze rau qhov pib siab ntawm lub tshuab pa cua, nws qeeb, thiab ua npuas ncauj ntsws yuav tsum tsim nyog txo cov khoom siv dawb. (Nws tuaj yeem muab sau ua qhov yoojyim xws li: ntau cov khoom siv dawb)
