Polyisocyanurate rwb thaiv tsev cov ntaub ntawv tam sim no siv rau hauv cov khoom siv rwb thaiv tsev, yog qhov kev xaiv zoo rau lub xyoo pua li no.Qhov kev soj ntsuam ntawm polyisocyanurate npuas yog hu ua txheej txheem ntawm lub neej voj voog tsom ntawm cov khoom raw mus rau cov ntaub ntawv pov thawj cov ntaub ntawv pov thawj. piv tau cov ntsiab lus nrog lwm cov roj carbon txo qis dua.Qhov rov qab yog ib feem ntawm cov khoom siv hluav taws xob polyisocyanurate tau ua tiav.
Polyamide cyanuric acid ester khoom, tshwj xeeb tshaj yog cov ASTM C1289 tsis ruaj rau cov dej haus (Polysocyanate rwb thaiv tsev tswj) ntawm qib 1 Ⅱ qauv, muaj ob qho khoom siv tom qab siv, kev siv dua thiab siv cov khoom qub tom qab. phaj, siv tau dua 24% (qhov sib piv), 15% (qhov sib piv) yuav siv tau hauv kev lag luam tom qab kev tsim rov qab, feem ntau ntawm cov kev rov zoo thiab rov ua haujlwm ntawm daim phaj.Tiam sis, muaj tam sim no muaj caij nyoog nce lub nqi rov qab thiab ua dua ntawm cov hluav taws xob polyurethane yog nyob rau hauv txoj kev.Txawm tias nws yog qhov yooj yim tshaj rau cov khoom siv thermoplastic xws li cov polyethylene, cov khoom siv thawv tawm roj xws li polyisocyanurate kuj tseem siv tau.
Polyisocyanurate rwb thaiv tsev tswj khoom thiab lawv txoj kev sim tau hloov thiab tsim kom tau raws li cov cai ntawm lub xyoo pua 21st ru.Thaum muaj qee cov ntsiab lus tseem ceeb:
1. Kev sib piv ntawm IECC 2012 tsab thiab raeash90.1-2004 tau ua rau kom muaj kev tiv thaiv yam tsawg kawg nkaus rau cov ntaub ntawv pov thawj, nrog rau qhov nce ntawm 80% ntawm yim lub tsaam thawj.
2. Roof renovation coj zoo rau kev txuag hluav taws xob, uas tuaj yeem pom los ntawm cov kev hloov hauv lub zog specifications.Haus tus neeg sawv cev Dr. Hoof hais tias cov teebmeem ntawm kev lag luam muaj me dua li kev xav tau.
3. Lub tshuab hluav taws xob ua rau polyisocyanurate qhia tau tias nws cov txiaj ntsig zoo ib puag ncig thiab nws qhov chaw zoo siab ntawm kev lom zem dua.
4. Cov hauj lwm ntawm lub xyoo dhau los tau piav qhia txog cov teeb meem ntawm kev ruaj ntseg ntawm qhov teeb meem, thiab tau tsim thiab siv cov kev xeem tshiab kom paub meej tias muaj kev hloov zoo ntawm cov khoom txawb hluav taws hauv qhov no.
