Cov lus qhia ua haujlwm
Tsis txhob siv lub tshuab PUR kub yaj kua nplaum nyob ib puag ncig nrog cov khoom tsis zoo lossis cov khoom tawg lossis cov pa roj. Cov khoom tawg yooj yim thiab tawg yuav tsum tsis txhob muab khaws cia ib ncig ntawm cov khoom siv tshuaj tsuag ntawm PUR kub yaj kua nplaum tshuab.
Tsis txhob siv lub tshuab kub yaj kua nplaum uas tsis muaj cov cuab yeej tiv thaiv tsim nyog thiab cov rwb thaiv tsev zoo lossis cov khoom tiv thaiv.
Tsuas yog cov neeg ua haujlwm tau txais kev cob qhia raug tso cai kom tshem tawm thiab kho PUR kub yaj kua nplaum tshuab thaum yuav tsum tau kho.
Thaum lub sij hawm installation, PUR kub yaj kua nplaum tshuab yuav tsum tsis txhob muab tso rau hauv zoo-ventilated tej yam kev mob los yog ib puag ncig nrog ceev-tsav cua. Kev nrawm nrawm tuaj yeem ua rau cov nplaum txau los ntawm cov kua nplaum kub yaj nozzle sib dhos kom txias sai, ua rau txoj hlua khi thiab cuam tshuam rau cov nplaum zoo.
PUR kub yaj kua nplaum tshuab yuav tsum tsis txhob ua thaum lub ambient kub yog qis dua -20 degree los yog siab tshaj 80 degree .
Xyuas kom tsis txhob muaj huab cua ceev ceev hauv ib puag ncig uas siv PUR kub yaj kua nplaum tshuab. Kev nthuav tawm PUR cov nplaum nplaum thiab cov nplaum nplaum nplaum rau cov cua nrawm nrawm yuav cuam tshuam rau cov kua nplaum kub yaj ntawm PUR kub yaj kua nplaum tshuab vim cua txias sai, ua rau lub zog pov tseg.
Thaum ntxiv PUR kub yaj nplaum nplaum, xyuas seb PUR nplaum nplaum puas yog deformed. PUR polyurethane kub yaj nplaum nplaum yuav tsum tau muab pov tseg kom tsis txhob ua rau lub siab phaj ntawm PUR kub yaj kua nplaum tshuab.
Thaum ntxiv PUR kub yaj nplaum nplaum, xyuas seb PUR nplaum nplaum puas yog deformed. PUR polyurethane kub yaj nplaum nplaum yuav tsum tau muab pov tseg kom tsis txhob ua rau lub siab phaj ntawm PUR kub yaj kua nplaum tshuab.
Thaum lub tshuab PUR kub yaj kua nplaum tsis siv rau lub sijhawm ntev, cov cua kub siab phaj ncig yuav tsum tau muab ntim nrog cov roj silicone kom ntseeg tau tias qhov ua tau zoo ntawm PUR kub yaj nplaum nplaum hauv cov kua nplaum.
PUR kub yaj nplaum tshuab yog lub iav twj tso kua mis raws li lub zog daim ntawv los thauj lub molten lub xeev, lub tshuab yog ib tug ntau yam ntawm viscosity ntawm PUR kub yaj nplaum khoom.
