Polyester polyol siv rau Rigid ua npuas ncaujtuaj yeem siv dav hauv tub yees, txias cia, tshuaj tsuag, hnub ci zog, thermal pipelines, lub tsev rwb thaiv tsev thiab lwm qhov chaw ntawm cov tawv nqaij npuas muaj pes tsawg leeg, qee cov khoom siv nplaum.
Polyester polyols feem ntau yog aromatic polyester polyols npaj los ntawm polycondensation los yog hloov pauv ntawm phthalic anhydride, diethylene glycol thiab lwm yam ntaub ntawv raw. Lawv tsuas yog siv nyob rau hauv lub tshav pob ntawm rigid ua npuas ncauj thiab adhesives. Lawv muaj qhov zoo ntawm cov ntxhiab tsw, tsis muaj xim, muaj kev ua haujlwm siab, zoo heev hydrolysis stability, siab aromatic cov ntsiab lus, zoo stability thiab fluidity ntawm cov ntaub ntawv sib xyaw, Thiab cov qauv khoom tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.
Cov khoom siv ntawm polyester polyols no tuaj yeem siv dav hauv tub yees, txias cia, txau, hnub ci zog, thermal pipelines, lub tsev rwb thaiv tsev thiab lwm qhov chaw ntawm cov khoom ua npuas ncauj nyuaj, qee cov khoom siv nplaum.

Kev siv polyurethane
Polyurethane yog dav siv nyob rau hauv ntau yam ntaub ntawv xws li tej plastics, elastomers, fibers, nto txheej, adhesives, sealants thiab foams.
PU yog tam sim no nyob rau hauv ntau yam kev lag luam daim ntaub ntawv xws li rooj zaum, ntim, khau, khoom siv, kev tsim kho thiab rooj tog.PU tam sim no suav hais tias yog ib qho ntawm cov khoom siv zoo tshaj plaws rau kev rwb thaiv tsev, txo cov thickness thiab cov nqi, nrog rau cov conductivity tsawg thiab siab heev. Ecoeficiency Performance index kom txuag hluav taws xob.
Yog li nruj PU foams yog siv tshwj xeeb tshaj yog nyob rau hauv engineering daim ntaub ntawv xws li rwb thaiv tsev cov ntaub ntawv, automotive qhov chaw, thiab cov khoom siv.
Ployester rigid ua npuas ncauj daim ntawv thov
Polyester rigid foams yog tam sim no siv nyob rau hauv ntau daim ntawv thov.
Lawv yog siv los ua cov ntaub npog thiab cov ntaub thaiv phab ntsa, cov phab ntsa muab faib, tshem tawm cov ceilings hauv cov chaw lag luam, cov chaw tsim kho thiab cov khw muag khoom txias.
Lub hauv paus txheej txheem yog feem ntau yog polyester rwb thaiv tsev pawg thawj coj saib uas muaj cov txheej txheem nrog ib tug tseem ceeb ntawm nruj polyurethane PIR ua npuas ncauj thiab ib tug hlau txheej rau sab nraum.
Sandwich panels yog siv rau hauv cov ntawv thov uas yuav tsum muaj kev sib xyaw ua ke ntawm cov qauv nruj thiab qhov hnyav tsawg. Qhov nrov ntawm
polyester ua npuas ncauj yog loj hlob tas li, raws li nws muaj ntau yam zoo, xws li:
1, hluav taws kub tsis kam,
2, suab rwb thaiv tsev,
3, thermal rwb thaiv tsev,
4, lub lightness ntawm cov txheej txheem,
5, yooj yim sib sau ua ke yam tsis xav tau cov cuab yeej hnyav,
6, tuaj yeem ntsia tau rau txhua qhov huab cua,
7, muaj peev xwm ntawm disassembling thiab rov siv cov laug cam hauv lwm qhov chaw.
