Dab tsi yog qhov sib xyaw polyol rau chav txias sandwich panels?
Kev sib xyaw ua ke polyol tshwj xeeb cov qauv rau chav txias sandwich panels muab cov thermal efficiency, qhov seem ruaj khov txias {pob zeb tsim cov kev xav tau. Txawm hais tias koj tsim cov chaw khaws cia ua haujlwm hauv tub yees, ua lag luam ua lag luam, lossis txias rau lub hauv paus, txoj cai polyurethane uas cov kev pab cuam siab uas muaj lub neej pabcuam ruaj khov.
Blend polyol rau cov chav txias txias yog qhov sib xyaw ua npuas dej ntawm polyester) polyols, kaw {} Cov qauv xov tooj ntawm tes thiab kev ua tau zoo heev. Cov qauv sib npaug sib npaug, cream thiab cov qauv kev tswj hwm, cov qauv xov tooj tswj thiab cov khoom siv mechans ua tau yooj yim kub ntau yam.
Kev ua npuas ncauj siab tsim tawm: Rigid Feamer ua los ntawm cov polyol sib xyaw ua ke muab cov nqi zoo heev (tsis muaj nqi
Tsawg thermal bridging & ruaj r - tus nqi: kaw} Cov khoom noo, khaws cov khoom siv rwb thaiv tsev nyob ruaj khov.
Sab Sij Hawm Stability: Panels khaws cov duab thiab tuab nyob rau hauv khov / thaws {}} tseem ceeb rau kev ua tub yees thiab lub qhov rooj sib xyaws.
Cov neeg kho tshuab zoo zog: Cov tub ntxhais ua npuas ncauj txhawb nqa vaj huam sib luag cov rooj sib tham (hlau lossis composite tawv nqaij) thiab tiv thaiv kev sib tsoo, thauj khoom thiab kev ntxhov siab.
Kev ua nrawm & kev ua kom zoo ua kom zoo thiab khiav cov yam ntxwv cia kom muaj kev sib txuas ua ke tsis tu ncua, nrog cov ceev tsis sib xws thiab tsawg kawg ntawm seem.
Kev xaiv hluav taws xob ua tau: Cov qauv tuaj yeem raug mus ntsib cov nplaim hluav taws xob hauv tebchaws los ntawm kev ntxiv cov nplaim hluav taws uas tsim nyog thaum ua kom cua sov thiab tshuab.
Polyol hauv paus: Polyether Polyols feem ntau yog siv rau hydrolytic ruaj khov thiab tsawg - kub ua tau zoo; Polyester Polyols tuaj yeem sib xyaw kom nce adhesion thiab compressive lub zog uas xav tau.
Kev ua haujlwm & OH NOJ: HOM PHIAJ UA HAUJ LWM THIAB Hydroxyl tooj kom tau txais Rosslink Densual Polyols ntau yam nyob ntawm cov phiaj ntom ntom thiab lub zog.
Viscosity: me ntsis viscosity txhim kho kev sib xyaw thiab cov tsis taus rau cov vaj huam sib luag tav.
Tshuab cov sawv cev: Niaj hnub nimno qis {{mwp lub cev lossis dej {{
Ntxiv: catalysts, surfactants thiab cell - stabilizers tswj cov mis lub sij hawm thiab qhov loj me; nplaim taws retardants thiab nucileating tus neeg sawv cev muaj ntxiv raws li yuav tsum tau ua.
Target densities: For cold room panels, typical core densities range from ~35–45 kg/m³ for low-temperature applications - tuned to balance strength and thermal performance.
Kev Ua & Tswjhwm Zoo
Tswj kev tswj nruj ntawm cov chaw kub thiab ntsuas kev ntsuas kom ntseeg tau cov qauv kev coj ua thiab kev ua haujlwm them.
Saib xyuas cov sijhawm noj qab zib, nce profile thiab cov tub ntxhais ntom ntom hauv lub sijhawm tiag tiag kom txo qis kev hloov pauv.
Cov nplaum ua cov nplaum rau cov cuab yeej hlau, lub zog compressive thiab thermal conductivity xyuas yog txheem QC cov tshev ua ntej ua zaub mov xa tuaj.
