Rigid polyurethane ua npuas ncauj, hu ua rigid polyurethane ua npuas ncauj, yog thib ob tsuas yog hloov tau yooj yim polyurethane ua npuas ncauj nyob rau hauv tus nqi ntawm cov khoom polyurethane.
Polyurethane rigid foams feem ntau yog kaw-cell qauv, uas muaj cov thermal rwb thaiv tsev zoo, lub teeb yuag, muaj zog tshwj xeeb, kev tsim kho yooj yim thiab lwm yam zoo heev.
Nyob rau tib lub sijhawm, lawv kuj muaj cov yam ntxwv ntawm lub suab rwb thaiv tsev, kev poob siab tsis kam, hluav taws xob rwb thaiv tsev, kub tsis kam, txias tsis kam, hnyav tsis kam, thiab lwm yam, thiab tau siv dav hauv insulating cov ntaub ntawv rau cov tub yees thiab lub freezers, txias cia, txias tsheb thauj khoom, tsev. , cov tso tsheb hlau luam, thiab cov kav dej yog siv nyob rau hauv cov sij hawm uas tsis yog insulated, xws li imitation ntoo, ntim khoom, thiab lwm yam.
Feem ntau hais lus, rigid polyurethane ua npuas ncauj nrog qhov ntom ntom yog tsuas yog siv los ua cov khoom siv hluav taws xob (thaum tshav kub kub), thiab cov khoom siv polyurethane nruj nrog qhov ntom ntom tuaj yeem siv los ua cov khoom siv (imitation ntoo).
Rigid polyurethane ua npuas ncauj yog feem ntau foamed ntawm chav tsev kub, thiab cov txheej txheem molding yog kuj yooj yim.Raws li qib ntawm kev tsim kho tshuab, nws tuaj yeem muab faib ua phau ntawv foaming thiab mechanical foaming;raws li lub siab thaum lub sij hawm foaming, nws yuav muab faib ua high-pressure foaming thiab low-pressure foaming;Raws li txoj kev molding, nws tuaj yeem muab faib ua cov foaming thiab txau foaming.
Kev siv tseem ceeb ntawm polyurethane rigid ua npuas ncauj yog raws li nram no:
1. Cov khoom siv khov thiab cov tub yees hauv cov khoom noj thiab lwm yam kev lag luam: xws li cov tub yees, lub freezers, txias cia, cov tsheb tub yees, thiab lwm yam., polyurethane rigid foam yog cov khoom siv rwb thaiv tsev zoo tshaj plaws rau cov khoom khov thiab cov tub yees.
2. Rwb thaiv tsev ntawm cov khoom siv hauv tsev: xws li lub tank cia, cov kav dej, thiab lwm yam.
3. Cov khoom siv hauv tsev: Hauv cov teb chaws tsim kho hauv Europe thiab Amelikas, rigid polyurethane ua npuas ncauj rau kev tsim kho suav txog li ib nrab ntawm tag nrho cov khoom siv ua npuas ncauj, uas yog ntau tshaj li ib zaug ntawm cov npuas dej khov rau cov tub yees thiab lub freezers;nyob rau hauv Suav teb, nruj ua npuas ncauj yog siv nyob rau hauv kev tsim kho kev lag luam.Daim ntawv thov tsis yog dav li nyob rau hauv Western teb chaws tsim, yog li lub peev xwm rau kev loj hlob yog loj heev.
4. Kev lag luam tsheb thauj mus los: xws li tsheb ru tsev, qhov chaw sab hauv, thiab lwm yam.
5. Imitation ntoo: high-density (density 300^700kg/m3) polyurethane rigid ua npuas ncauj los yog iav fiber reinforced rigid foam yog cov qauv ua npuas ncauj yas, los yog imitation ntoo, uas muaj zog, zoo toughness, ntom thiab tawv crust, txheej txheem molding yooj yim, Nws muaj cov yam ntxwv ntawm kev ua haujlwm siab, siab zog dua li cov ntoo ntuj, thiab qis dua li cov ntoo ntuj.Nws tuaj yeem hloov ntoo rau ntau yam khoom siv high-end.
6. Cov khoom siv potting, thiab lwm yam.
Txhua yam polyurethane nyuaj ua npuas ncauj khoom koj xav ua, txais tos los tham nrog peb, peb tuaj yeem muab cov kev daws teeb meem zoo tshaj plaws.
