Polyurethane txau yog hais txog cov txheej txheem ntawm kev siv cov cuab yeej tshaj lij, sib xyaw isocyanate thiab polyether (feem ntau hu ua cov khoom siv dub thiab dawb) nrog cov neeg ua npuas dej, cov khoom siv hluav taws xob, cov nplaim hluav taws kub hnyiab, thiab lwm yam, los ntawm kev siv lub zog siab kom ua tiav cov txheej txheem polyurethane foaming ntawm qhov chaw.Nws yuav tsum tau muab sau tseg tias polyurethane muaj rigid ua npuas ncauj thiab saj zawg zog ua npuas ncauj.Phab ntsa rwb thaiv tsev feem ntau yog siv rau cov ua npuas ncauj nruj, thiab ua npuas ncauj hloov tau ua lub luag haujlwm ntxiv.Vim nws txoj kev yooj yim tsim thiab zoo kawg nkaus thermal rwb thaiv tsev nyhuv, polyurethane spraying yog dav siv nyob rau hauv lub tsev ru tsev thiab phab ntsa rwb thaiv tsev.

Polyurethane txau cov cuab yeej siv dav hauv: qhib cell,tsev sab nrauv phab ntsa thermal rwb thaiv tsevtshuaj tsuag,sab hauv phab ntsa thermal rwb thaiv tsevtxau, txias cia thermal rwb thaiv tsev spraying, thermal rwb thaiv tsev spraying, nqaij qaib ua liaj ua teb rwb thaiv tsev spraying, thiab lwm yam.Tub tub yees thermal rwb thaiv tsev spraying, tsheb suab rwb thaiv tsev spraying, cabin thermal rwb thaiv tsev spraying, tiv thaiv thermal rwb thaiv tsev txau rau dej ntawm lub ru tsev, LNG tank anti-corrosion thermal rwb thaiv tsev txau, hnub ci dej rhaub, tub yees, lub freezer, thiab lwm yam.

Qhov zoo ntawm polyurethane txau

1. Cov nyhuv thermal rwb thaiv tsev zoo dua

2. High bond zog

3. Lub sijhawm siv sijhawm luv

Disadvantages ntawm polyurethane txau

1. Tus nqi siab

2. txwv los ntawm ib puag ncig sab nraud

Daim Ntawv Thov Ntawm Polyurethane Txau Hauv HVAC Kev Lag Luam

Vim nws tus nqi siab, daim ntawv thov ntawm polyurethane spraying nyob rau hauv HVAC kev lag luam yog feem ntau yog concentrated nyob rau hauv txias cia, tub yees tsheb thiab lwm yam teb uas muaj kuj thermal rwb thaiv tsev yuav tsum tau.

Tsis tas li ntawd, qee lub tsev high-end tej zaum yuav siv polyurethane txheej rau phab ntsa rwb thaiv tsev rau lub hom phiaj ntawm kev thov rau cov ntawv pov thawj hauv teb chaws xws li cov tuam tsev ultra-low zog.
