Refractory Brick Mullite Cib
Mullite bricks yog tsim los ntawm kev ua tib zoo xaiv cov ntaub ntawv raw nrog siab alumina thiab silica cov ntsiab lus. Cov khoom siv raw yog sib xyaw, zoo li hauv cib los ntawm cov txheej txheem molding, thiab tom qab ntawd raug rho tawm haujlwm ntawm qhov kub thiab txias kom ua tiav cov khoom xav tau.
Cov khoom tshwj xeeb ntawm mullite cib ua rau lawv xaiv zoo rau cov ntawv thov uas qhov kub tsis kam thiab thermal stability yog qhov tseem ceeb. Lawv muaj lub siab refractoriness, cia lawv tiv taus kub xws li 1600 degree (2912 degree F) mus txog 1800 degree (3272 degree F) lossis siab dua. Mullite bricks nthuav tawm cov thermal expansion tsawg, txo qhov kev pheej hmoo ntawm thermal stress thiab tawg thaum lub sij hawm cua sov thiab cua txias.
Cov cib no kuj muaj cov tshuaj tiv thaiv zoo, ua rau lawv haum rau ib puag ncig nrog cov roj corrosive lossis cov hlau molten. Lawv muaj nruab nrab mus rau siab mechanical zog, ua rau lawv tiv taus mechanical kev nyuaj siab thiab puas.
Cov khoom luv luv
Mullite bricks yog ib hom refractory cib uas feem ntau yog tsim los ntawm mullite, ib tug ntxhia compound nrog cov tshuaj formula Al6Si2O13. Mullite paub txog nws zoo heev thermal stability, siab refractoriness, thiab tsawg thermal expansion coefficient, uas ua rau mullite bricks haum rau siv nyob rau hauv ntau yam high-temperature daim ntaub ntawv.

Khoom zoo
Kub Kub Resistance: Mullite bricks muaj qhov siab refractoriness, cia lawv tiv taus kub xws li 1600 degree (2912 degree F) mus txog 1800 degree (3272 degree F) lossis siab dua. Lawv tuav lawv cov qauv kev ncaj ncees thiab txhua yam khoom txawm tias nyob rau hauv huab cua kub heev.
Thermal Stability: Mullite bricks pom zoo thermal stability, txhais tau tias lawv muaj peev xwm tiv taus rov qab thermal cycles yam tsis muaj kev puas tsuaj loj. Lawv muaj cov thermal expansion coefficient tsawg, uas yuav pab txo qis kev pheej hmoo ntawm kev tawg lossis tawg vim thermal stress.
Chemical Resistance: Mullite bricks muaj kev tiv thaiv zoo rau tshuaj tua kab mob, ua rau lawv haum rau siv nyob rau hauv ib puag ncig nrog corrosive gases los yog molten hlau. Lawv feem ntau siv rau hauv cov ntawv thov uas muaj cov kua qaub, alkalis, thiab lwm yam tshuaj lom neeg.
Ntim
Ntoo Crates: Mullite bricks yog ua tib zoo teem thiab teem rau hauv cov ntoo crates ruaj khov. Cov cib feem ntau sib cais thiab tiv thaiv los ntawm cov duab los yog ua npuas ncauj ntxig los tiv thaiv kev puas tsuaj thaum thauj. Ntoo crates muab kev tiv thaiv zoo heev tiv thaiv kev cuam tshuam thiab ua kom muaj kev ruaj ntseg thaum tuav thiab xa khoom.
Pallets: Mullite cib tuaj yeem muab tso rau ntawm pallets thiab muab qhwv ruaj khov nrog zaj duab xis ncab lossis shrink qhwv kom tuav lawv ua ke thiab tiv thaiv lawv los ntawm ya raws thiab plua plav. Pallets yooj yim rau tuav nrog forklifts lossis pallet jacks.
Steel Strapping: Txhawm rau muab kev txhawb nqa ntxiv, steel strapping yuav siv tau los tiv thaiv cov pob zeb sib tsoo ntawm cov pallets lossis hauv cov ntoo crates. Qhov no pab tiv thaiv kev hloov pauv lossis kev puas tsuaj thaum caij tsheb npav.
