Rigid polyurethane(PU) ua npuas ncauj tau dhau los ua ib qho ntawm cov khoom siv rwb thaiv tsev tseem ceeb tshaj plaws hauv kev lag luam khoom siv hauv tsev niaj hnub no. Paub txog nws cov thermal rwb thaiv tsev zoo heev, txhua yam muaj zog, thiab ntev - lub sij hawm ruaj khov, PU ua npuas ncauj yog dav siv nyob rau hauv tub yees, freezers, dej rhaub, thiab lwm yam khoom siv hauv tsev uas xav tau kev tswj xyuas thermal zoo thiab txhim khu kev qha.
Superior rwb thaiv tsev Performance for Refrigerators and Freezers
Hauv cov khoom siv tub yees, thermal efficiency txiav txim siab siv hluav taws xob thiab ntev - tus nqi khiav lag luam. Rigid PU ua npuas ncauj muaj ib qho ntawm cov thermal conductivity qis tshaj ntawm cov khoom siv hluav taws xob ua lag luam, tso cai rau cov tuam txhab lag luam kom ua tiav cov txheej txheem rwb thaiv tsev zoo dua yam tsis muaj kev cuam tshuam kev ua haujlwm. Nws kaw -cov qauv ntawm tes ua kom txo tau cov cua sov thiab tiv thaiv kev nkag mus ntawm cov dej noo, kom ntseeg tau tias qhov kub thiab txias sab hauv tseem nyob ruaj khov txawm tias nyob rau hauv qhov qhib qhov rooj thiab qhov kub thiab txias sab nraud.
Dimensional Stability thiab Structural Strength
Cov khoom siv hauv tsev xav tau cov ntaub ntawv uas tswj cov duab thiab kev ua haujlwm zoo tshaj plaws rau ntau xyoo ntawm kev siv. Rigid PU ua npuas ncauj muab kev ruaj ntseg zoo tshaj plaws, tiv thaiv shrinkage thiab deformation thaum kho thiab ua haujlwm ntev -. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv lub tub yees, qhov chaw ua npuas ncauj tsis yog tsuas yog rwb thaiv tsev xwb tab sis kuj yog ib qho kev txhawb nqa ntawm cov vaj huam sib luag sab hauv thiab sab nrauv. Lub txee ua rau muaj zog, hnav, thiab tiv taus kev co.
Compatibility nrog Pentane Blowing Agent Systems
Rigid PU ua npuas ncauj formulations siv nyob rau hauv cov khoom siv hauv tsev feem ntau cia siab rau cyclopentane los yog pentane blends raws li tshuab tshuab vim lawv ib puag ncig zoo thiab zoo heev compatibility nrog polyester polyols. Pentane cov tshuab ua kom lub cev ua npuas ncauj nthuav dav, cov qauv ntawm tes zoo, thiab kev ua haujlwm siab rwb thaiv tsev, thaum ua tau raws li kev cai nruj ib puag ncig. PTA-raws li polyester polyols, feem ntau siv nyob rau hauv cov tshuab no, muab zoo flowability thiab zoo ib yam ua npuas ncauj ntom ntom, ua rau lawv zoo heev haum rau lub tub yees thiab lub freezer ntau lawm kab.
Daim ntawv thov tshaj lub tub yees
Txawm hais tias lub tshuab tub yees tseem yog qhov loj tshaj plaws ntawm daim ntawv thov, PU ua npuas ncauj kuj tseem siv rau hauv:
Electric dej rhaub - muab thermal rwb thaiv tsev kom txo tau kub
Cov khoom lag luam txias thiab cov rooj sib tham - tswj qhov kub thiab txias nyob rau lub sijhawm ua haujlwm ntev
Ice makers thiab vending machines - muab ob qho tib si rwb thaiv tsev thiab cov khoom siv ntxiv
Kev lag luam txias- cov khoom siv saw - txhim kho durability thiab zog efficiency
Nws lub peev xwm los txuas seamlessly nrog hlau, yas, thiab cov khoom sib xyaw ua rau PU ua npuas ncauj ua tau ntau yam khoom siv thoob plaws ntau yam khoom siv.
Zog Efficiency thiab Environmental Compliance
Nrog rau cov qauv hluav taws xob thoob ntiaj teb tau dhau los ua nruj zuj zus, cov tuam txhab lag luam tau hloov mus rau siab - cov ntaub ntawv rwb thaiv tsev ua haujlwm uas txhawb kev siv hluav taws xob tsawg thiab txo qis carbon emissions. Rigid PU ua npuas ncauj ua tau raws li cov kev cai no los ntawm kev sib txuas ua haujlwm zoo rwb thaiv tsev nrog lub neej ua haujlwm ntev. Tsis tas li ntawd, niaj hnub pentane-raws li PU systems zam ozone-depleting tshuaj thiab pab manufacturers ua raws li thoob ntiaj teb kev cai.
