Cov ntaub ntawv rwb thaiv tsev kub yog cov khoom siv los yog cov khoom siv los txo qis kev hloov pauv ntawm lub zog hluav taws xob ntawm cov khoom lossis ib puag ncig nrog qhov sib txawv ntawm qhov kub thiab txias. Lawv yog ib qho tseem ceeb rau kev txuag lub zog, tswj qhov kub thiab txias, thiab ua kom muaj kev nyab xeeb hauv ntau yam kev siv. Txhua yam khoom muaj qhov tshwj xeeb zoo xws li thermal tsis kam, hluav taws kub tsis kam, eco-friendliness, lub teeb yuag, lossis tsim nyog rau qhov chaw kub kub. Kev xaiv ntawm cov khoom siv rwb thaiv tsev nyob ntawm cov yam ntxwv xws li qhov kub thiab txias, hom kev thov, kev txiav txim siab nqi, thiab kev txhawj xeeb ntawm ib puag ncig.
kev faib tawm ntawm cov khoom siv rwb thaiv tsev kub
Yog vim li ntawd, xaiv txoj cai ntawm Cov Khoom Siv Hluav Taws Xob Kub Kub yog qhov tseem ceeb. Ntawm no peb yuav saib 4 hom khoom siv rau kev lag luam kub rwb thaiv tsev, lawv cov khoom, qhov zoo thiab qhov tsis zoo.
Mineral ntaub plaub
Mineral wool rwb thaiv tsev yog tsim los ntawm kev sib tov ntawm iav, pob zeb los yog slag uas yog rhuab mus rau qhov kub thiab txias thiab ces spun rau hauv ib lub teeb fiber ntau qauv. Ib qho khoom siv pob zeb hauv av yog Superwool, uas yog alkaline earth silicate wool (AES). Mineral wools zoo li Superwool feem ntau yog siv rau hauv cov khoom siv ua haujlwm tsis tu ncua, nrog rau cov khoom siv hauv tsev.
Ceramic fiber ntau
Ceramic fiber ntau yog tsim los ntawm melting alumino-silicate cov ntaub ntawv nyob rau hauv lub cub tawg, los ntawm cov kwj deg yog poured thiab txias rau cov fiber strands. Nws yog incredibly lub teeb yuag thiab resistant rau thermal shock. Ceramic fiber ntau feem ntau siv rau hauv cov khoom siv hluav taws xob, cov yeeb nkab rwb thaiv tsev, kev sib txuas txuas, cov ntsaws ruaj ruaj, kev tiv thaiv hluav taws, qhov cub hauv ob sab phlu, thiab ntim rau qhov kub thiab txias.
Hluav taws kub
Firebricks yog blocks ntawm refractory ceramic khoom, ua los ntawm fireclay - ib tug ntxhia aggregate muaj li ntawm hydrous silicate ntawm txhuas. Lawv tuaj yeem tiv taus qhov kub thiab txias thiab tuaj yeem pab ua kom muaj zog ntau dua. Txawm hais tias lawv muaj cov khoom siv thermal zoo dua, ib qho ntawm lawv qhov tsis zoo yog qhov loj dua, bulkier thiab hnyav dua li lwm cov ntaub ntawv. Firebricks feem ntau yog siv rau hauv kev ua cov hlau, petrochemicals thiab ceramics. Lawv kuj siv tau rau hauv kilns, qhov cub, qhov cub, forging furnaces, blast furnaces thiab flues.
Mica
Mica yog cov ntxhia hauv ib txwm muaj nrog cov khoom siv thermal thiab hluav taws xob zoo dua. Nws ua rau cov ntawv nyias nyias, txhais tau tias nws hloov tau yooj yim heev thiab tuaj yeem txiav, stamped thiab zoo li tus rau hauv ntau hom. Pure phlogopite mica tuaj yeem tiv taus qhov kub txog li 1000C. Mica feem ntau suav nrog lwm cov ntaub ntawv xws li cov ntaub plaub ntxhia, iav lossis ceramic fibers los txhim kho nws cov thermal thiab lub cev. Mica composite laminates muaj nyob rau hauv daim ntawv, yob los yog raj daim ntawv, nrog rau daim ntawv thiab yob yog feem ntau siv nyob rau hauv daim ntawv thov xws li rauv taws.
