Dab tsi yog daim ntawv thov ntawm polyurethane rau rwb thaiv tsev?
1.Cov khoom siv tub yees- xws li cov tub yees, lub freezers, txias cia, tsheb tub yees thiab lwm yam thermal rwb thaiv tsev
2.Industrial khoom rwb thaiv tsev - xws li cia tank, pipelines, thiab lwm yam.
3.Building engineering -- sab nrauv phab ntsa thiab ru tsev rwb thaiv tsev
Dab tsi yog Qhov Zoo ntawm polyurethane rwb thaiv tsev yeeb nkab khoom?
1. muaj zog tus kheej nplaum (tsis xav tau cov ntaub ntawv sib txuas nruab nrab),
cov khoom sib txuas nrog lub ru tsev thiab sab nrauv phab ntsa, nrog cov cua tsis zoo thiab tsis zoo cua siab
2.Qhov kev siv tshuaj tsuag tag nrho tuaj yeem tshem tawm tag nrho cov "kub seem" thiab "txias choj"
3. yoog raws kev siv thev naus laus zis tuaj yeem tiv thaiv kev tawg ntawm cov txheej txheem dej tsis zoo
4. Mechanized lag luam, tsis siv neeg batching, uniform zoo, ceev kev tsim kho, lub voj voog luv
5.stable, ntev kev pab cuam lub neej, yuav tsis ua qias neeg ib puag ncig
Tom qab tawm hauv qhov hluav taws kub, nws yuav cia li tua, thiab nws tsuas yog carbonized thaum lub sij hawm combustion txheej txheem tsis dripping. Qhov loj thiab cov duab ntawm cov txheej carbonized yog qhov pib tsis hloov, uas tuaj yeem thaiv cov cua nkag thiab tiv thaiv kev sib kis ntawm hluav taws, thiab muaj kev ua tau zoo ntawm hluav taws.
Yuav ua li cas daws cov teeb meem hauv kev tsim kho ntawm polyurethane rwb thaiv tsev yeeb nkab?
Qhov tshwm sim no feem ntau tshwm sim nyob rau lub caij nplooj zeeg thiab lub caij ntuj no los yog thaum sawv ntxov kev tsim kho, vim tias qhov kub thiab txias tau poob qis los yog qhov kub thiab txias. Nws tuaj yeem daws tau los ntawm kev nce qhov kub thiab txias ntawm cov khoom siv dub.
Feem ntau, cov khoom siv dub kub nce mus rau 30-60 degree ., thiab qhov kub thiab txias nce mus rau 20-30 degree . Qhov tshwm sim no feem ntau tshwm sim nyob rau lub caij nplooj ntoos hlav thiab lub caij ntuj sov lossis thaum tav su kev tsim kho, vim tias qhov kub thiab txias dheev nce siab vim qhov kub thiab txias heev. Cov khoom siv dub tuaj yeem ua kom txias nrog dej txias lossis tso rau sab nraum zoov thaum hmo ntuj kom txias kom tsis txhob raug tshav ncaj qha.
Lub zog ua npuas ncauj ntawm polyurethane rwb thaiv tsev raj yog me me thiab ua npuas ncauj yog mos, uas yog tshwm sim los ntawm qhov tsis sib xws ntawm cov khoom siv dub thiab dawb, thiab feem ntau ntawm cov khoom siv dub tuaj yeem tsim nyog (1:1-1.05). Ua tib zoo tsis txhob ua kom qhov feem ntawm cov khoom siv dub loj dhau, txwv tsis pub, nws yuav ua rau ua npuas ncauj nkig thiab cuam tshuam rau kev ua haujlwm ntawm cov npuas dej.
