Cov kua dej txias txhawb nqa los ntawm ntau hom kev sib koom tes, feem ntau cov khoom siv los ntawm cov khoom siv thiab cov yam ntxwv ua haujlwm. Hom hom thiab lawv cov yam ntxwv tau teev hauv qab no:
Kev faib tawm los ntawm cov khoom siv
1. Polyurethane Khaub Ncaws Tiv Thaiv
Siab kaw - kev piv ntawm tes (ntau dua lossis sib npaug nrog 0.027 w / min k), thiab muaj zog compressive.
Zoo heev qis - kub kuj, nrog cov khoom siv tau muaj qhov ntsuas kub ntawm -196℃rau +120 degree. Feem ntau siv rau cryogenic pipelines xws li lng thiab kua nitrogen.
2. Polyisocyanurate (PIR) Lub Yeeb Yeeb Tiv Thaiv
Kev ntsuas hluav taws kub siab (txog B1), zoo dua siab- kub tsis kam rau polyurethane, nrog rau qhov ntsuas kub ntawm -180 teev rau {}}} degree.
Muaj lub zog compressive zog thiab cov tshuaj muaj zog ruaj khov ua rau nws haum rau qis - sov paus rau kev lag luam thiab kev lag luam hluav taws xob.
3. Ua npuas ncauj iav iav txias txhawb nqa
Ua los ntawm cov khoom siv inorganic, tsis yog -} {{{{1} {{{{{{4 4}} degree).
Txawm li cas los xij, lawv yog nkig heev thiab yuav tsum tau tiv thaiv los ntawm cov muaj feem cuam tshuam thaum lub sij hawm teeb tsa. Lawv feem ntau siv hauv kev ua haujlwm tshwj xeeb muaj feem cuam tshuam nrog kev sib txawv txias thiab kub siab.
4. Liab ntoo thuv khaub thuas rwb thaiv tsev yeeb nkab yeeb
Ntoo ntuj ntoo kho nrog corrosion thiab noo noo - ua pov thawj muaj qhov tsis tshua muaj cua sov conductivity thiab yog qhov pheej yig.
Haum rau cov qes - kub} sov cov kav dej ua haujlwm ntawm qhov kub siab dua -30 degree, xws li cua txias chilled dej tshuab.
5. Composite khaub thuas rwb thaiv tsev yeeb nkab yeeb tshuaj txhawb
Txheej txheej sab nraud ntawm cov hlau fiberglass lossis stainless hlau (corrosion tawm tsam thiab thauj khoom {{} paperethane / pir (thermal rwb thaiv tsev).
Ua ke lub zog siab nrog rwb thaiv tsev zoo heev thermal, lawv yog qhov tsim nyog rau kev ua kom haum ib puag ncig lossis rau cov kav dej loj.
