Polyurethane yog dab tsi?

Polyurethane yog ib hom yas uas yog abbreviated li PUR.Cov yas no belongs rau cov polymers thiab muaj ob ntu sib txawv: ntu tawv thiab ntu mos.Vim tias PU muaj ob qho tib si tawv thiab mos cov khoom siv yog rubbery.Dhau li ntawm ob ntu, PUR tuaj yeem muab faib ua cov khoom siv (txheej) thiab ua npuas dej.

Cov yas muaj nyob rau hauv ob qho tib si 1- thiab 2-cov khoom siv.Ob lub ntsiab lus muaj xws li cov khoom A, lub hauv paus cob, thiab cov khoom B, lub hardener.Nrog polyurethane resins koj siv lub hardener tshwj xeeb rau qee qhov chaw ntawm daim ntawv thov.Tom qab ntxiv cov kua hardener rau A tivthaiv, cov txheej txheem tshuaj tshwm sim.Cov txheej txheem no ua kom lub zog ntawm cov resin.Nyob ntawm seb hom hardener, qhov no yuav cuam tshuam qhov nrawm thiab cov khoom siv.Nrog PU nws yog ib qho tseem ceeb kom ua raws li cov proportions.Nyob ntawm seb hom ntu, koj cov khoom yuav nyob twj ywm los yog roj hmab elastic tom qab kho.Nrog cov npuas version, cov khoom nthuav dav hauv ntim raws li nws qhov ceev.

Kev siv ntawm polyurethane

Polyurethane resins tuaj yeem siv los ua coatings, primers, adhesives, lacquers, paints lossis casting resins.Xws li pob tshab thiab UV-resistant polyurethane xim rau hlau lossis ntoo.Zoo tagnrho rau kev ua tiav parquet lossis cam khwb cia hauv pem teb.Tsis tas li ntawd, cov khoom siv kuj yog siv los ua tawv tawv thiab siv rau hauv cov khau khau.

Daim ntawv thov muaj peev xwm ntawm polyurethane resins yog unlimited thiab kis thoob plaws ntau yam sectors.

PU Cast pem teb

Polyurethane cam khwb cia hauv pem teb tau txais kev muaj koob meej hauv kev lag luam hauv tsev hauv xyoo tas los no ua tiav rau qhov chaw nyob, chav ua noj thiab chav pw.Ua tsaug rau nws tus kheej-leveling cov khoom, cov resin no ua kom zoo nkauj heev thiab niaj hnub hauv pem teb tiav.Muaj nyob rau hauv cov xim sib txawv kom phim lub suab ntawm koj sab hauv.Ua tsaug rau nws cov khoom elastic, koj tuaj yeem siv nws nrog cov cua sov hauv qab thiab tau txais kev ruaj khov thiab hnav-resistant tag.

PUR xim Sealine

Ib qho kev siv ntau tshaj plaws ntawm PU yog ua kua roj vanish lossis txheej.Ua tsaug rau qhov zoo heev UV tsis kam, 2K polyurethane xim tau siv rau hauv cov ntawv thov kev lag luam rau xyoo.Tshwj xeeb tshaj yog nyob rau hauv kev thauj mus los, maritime thiab kev tsim kho sectors.Lub durability thiab siab gloss ua Sealine PUR ua tiav zoo tagnrho rau pleev xim koj lub nkoj.
