Cov ntaub ntawv rwb thaiv tsev yeeb nkab yog cov khoom siv ua haujlwm uas tau muab qhwv rau sab nraud ntawm cov kav dej kom txo tau cov cua sov los yog txias, tiv thaiv kev kub nyhiab thiab khov, thiab ua kom qhov kub ntawm qhov nruab nrab. Lawv lub hauv paus ntsiab lus zoo ib yam li cov paj rwb lossis lub thermos; lawv tuav lub zog lub xeev hauv cov yeeb nkab los ntawm kev cuam tshuam cov thermal conduction.
Lub luag haujlwm tseem ceeb suav nrog: kev txuag hluav taws xob thiab kev txo qis, txo qhov kub ntawm qhov poob ntawm chav, dej kub, lossis tub yees thaum thauj; kev tiv thaiv kev nyab xeeb, tiv thaiv kev kub hnyiab los ntawm qhov kub siab - cov kav dej kub, condensation ntawm qis- qhov kub ntawm cov yeeb nkab, lossis khov thiab tawg thaum lub caij ntuj no; thiab ua kom muaj kev ruaj ntseg ntawm cov txheej txheem kev lag luam.
Raws li lawv daim ntawv thiab kev ua tau zoo, cov ntaub ntawv rwb thaiv tsev zoo tuaj yeem muab faib ua plaub pawg:
- Ua ntej, cov ntaub ntawv fibrous, xws li pob zeb wool thiab iav ntaub plaub, yog siab -kub resistant thiab tsis yog -combustible, haum rau cov kav dej thiab cov ntawv thov uas muaj kev tiv thaiv hluav taws kub, tab sis muaj kev cuam tshuam rau cov dej noo.
- Thib ob, cov ntaub ntawv ua npuas ncauj, xws li roj hmab- cov ntaub txhuam cev yas thiab polyurethane, muaj qhov kaw- cov qauv ntawm tes uas tiv thaiv cov dej ntws tawm thiab cov dej sib xyaw ua ke, ua rau lawv tsim tshwj xeeb rau cov cua txias hauv nruab nrab cov kav dej txias thiab cov kav dej kub.
- Thib peb, granular lossis hmoov, xws li nthuav dav perlite thiab airgel xav, tuaj yeem tiv taus qhov kub siab lossis qis qis thiab siv rau hauv cov nroj tsuag hluav taws xob lossis cov kav dej liquefied natural gas.
- Plaub, cov ntaub ntawv sib xyaw, xws li nano-aerogel composite reflective txheej, muaj cov thermal conductivity tsawg heev thiab nyias nyias, tab sis yog kim thiab feem ntau siv hauv aerospace los yog siab -kawg industries.
Thaum xaiv cov ntaub ntawv rwb thaiv tsev, ntau qhov ntsuas tseem ceeb yuav tsum tau xav txog:
Qhov qis dua qhov thermal conductivity (λ tus nqi), qhov ua tau zoo ntawm kev rwb thaiv tsev; kev khiav hauj lwm qhov kub thiab txias yuav tsum phim qhov kub ntawm cov kav dej nruab nrab; Kev ntsuas hluav taws kub muaj ntau yam los ntawm Class A (tsis yog-combustible) mus rau Class B2 (combustible); thiab qhov nqus dej noo yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov kav dej qis - qhov kub thiab txias, vim tias qhov nqus dej yuav ua rau muaj kev puas tsuaj loj rau cov rwb thaiv tsev.
Thaum lub sij hawm installation, nws feem ntau muaj ib txheej rwb thaiv tsev thiab ib txheej tiv thaiv, xws li txhuas cladding los yog PVC, los tiv thaiv dej puas. Kev xaiv cov khoom siv rwb thaiv tsev kom zoo tuaj yeem txuag cov nqi hluav taws xob thiab txhim kho kev nyab xeeb thiab kev ua neej.
