Koj paub ntau npaum li cas txog kev kub siab resistantnon-hlau expansion pob qij txha?
Cov khoom tseem ceeb ntawm qhov kub-kub uas tsis yog-hlau expansion sib koom ua ke yog silica gel, fiber ntau ntaub thiab lwm yam ntaub ntawv. Ntawm lawv, fluorine roj hmab thiab silicone cov ntaub ntawv muaj qhov kub thiab txias tsis kam thiab corrosion kuj.
High-temperature non-metallic expansion joint yog ib yam khoom tshwj xeeb rau flue gas ducts. Piv nrog cov hlau expansion pob qij txha, non-metallic expansion joint muaj cov yam ntxwv ntawm tus nqi qis, kev tsim khoom yooj yim, thiab lub neej ntev. Txawm li cas los xij, cov khoom siv tau yooj yim rau kev laus tom qab raug kub hnyiab. Los ntawm qhov kev xav mus ntev, xws li cov kav dej kub kub hauv cov nroj tsuag cement thiab cov nroj tsuag steel, nws raug nquahu kom siv cov hlau tsis muaj steel kub-kub expansion pob qij txha.
Yuav ua li cas tsis-hlau expansion pob qij txha paub qhov kub thiab txias?
Cov pob qij txha tsis yog hlau feem ntau yog siv rau hauv cov pa roj flue thiab cov khoom siv tshem tawm plua plav, feem ntau yog nqus cov axial tshem tawm thiab ib qho me me ntawm radial hloov ntawm cov kav dej. Feem ntau, ib txheej ntawm PTFE daim ntaub, ob txheej ntawm non-alkali iav fiber ntau daim ntaub, thiab ib txheej ntawm silicone daim ntaub yog feem ntau siv rau non-metallic expansion pob qij txha. Xws li kev xaiv yog ib qho kev tsim qauv kev daws teeb meem los ntawm kev sim thiab ua yuam kev.
Txhawm rau ua haujlwm zoo dua rau peb cov neeg siv khoom, peb lub tuam txhab tau tshaj tawm cov ntaub ntawv kub-resistant fluorine daim kab xev, uas feem ntau yog siv rau high-temperature gas pipelines.
Cov kev sib txuas uas tsis yog xim hlau hloov tau tuaj yeem tsim cov khoom siv nrog qhov ntsuas kub ntawm 1000 ℃ rau koj los ntawm kev hloov pauv ntawm peb lub tuam txhab thev naus laus zis. Yuav kom ua tau raws li kev xav tau ntau ntxiv rau cov khoom siv thiab cov kav dej, peb lub tuam txhab tuaj yeem tsim cov kiv cua nthuav dav rau koj.
