Khoom Description

Magnesia-calcium bricks yog ua los ntawm high- lub teeb zoo- hlawv magnesia raw cov ntaub ntawv thiab siab - purity calcium raw cov ntaub ntawv, uas yog sintered ntawm high kub. Nws muaj kev tiv thaiv hluav taws zoo heev, tiv thaiv corrosion, hnav tsis kam thiab alkali tsis kam, thiab yog dav siv nyob rau hauv siab - kub lub sij hawm xws li siab - kub furnaces thiab tshuaj nroj tsuag. Nws muaj cov yam ntxwv ntawm zoo waterproofing, zoo thermal rwb thaiv tsev thiab zoo thermal shock kuj.

Khoom Categories:

Raws li cov qauv sib txawv, magnesia-calcium bricks yuav muab faib ua ob hom: zoo tib yam magnesia-calcium bricks thiab siab-purity magnesia-calcium bricks.

Ordinary magnesia-calcium bricks feem ntau yog siv rau hauv siab- cov khoom kub hauv metallurgy, boilers, iav, tshuaj lom neeg kev lag luam, kev tsim kho thiab lwm yam lag luam.

High-purity magnesia-calcium bricks muaj cov ntsiab lus qis ntawm graphite, aluminium fluoride, thiab lwm yam dua li cov magnesia zoo tib yam -calcium bricks, thiab tau dav siv hauv kev lag luam tshwj xeeb xws li silicon-magnesia furnaces thiab fiberglass reinforced plastics.

Cov khoomQhov zoo

1. Kev tiv thaiv hluav taws kub siab: Qhov hluav taws kub - tiv taus qhov kub ntawm magnesia-calcium cib tuaj yeem ncav cuag ntau tshaj 2000 degree, thiab tuaj yeem siv tau ntev hauv qhov chaw kub heev, uas tuaj yeem tiv thaiv kev nyab xeeb ntawm cov khoom siv;

2. Hnav tsis kam thiab corrosion kuj: Magnesia calcium bricks muaj siab hnav tsis kam thiab corrosion kuj, uas tuaj yeem tiv thaiv corrosion thiab poob ntawm cov khoom siv;

3. Tshuaj tiv thaiv: Magnesia-calcium bricks muaj kev tiv thaiv zoo rau cov tshuaj ib puag ncig xws li cov kua qaub thiab muaj zog alkali, thiab tuaj yeem tiv taus cov tshuaj tiv thaiv zoo;

4. Kev ua dej tsis zoo: Magnesia-calcium cib muaj cov khoom siv dej tsis zoo thiab tuaj yeem tiv thaiv corrosion thiab poob los ntawm qhov chaw ntub dej;

5. Zoo thermal rwb thaiv tsev: Magnesia-calcium cib muaj cov thermal rwb thaiv tsev zoo thiab tuaj yeem cais cov hluav taws kub hauv qhov kub siab - ib puag ncig;

6. Zoo thermal poob siab tsis kam: Magnesia-calcium bricks muaj thermal shock kuj zoo thiab tuaj yeem nyob ruaj khov nyob rau hauv ntev -lub sij hawm kub kub ib puag ncig.

7. It has light specific gravity and low density, about 50% lighter than ordinary bricks, which can effectively reduce the quality of the building and reduce the structural load;

8. Tsis yog- tshuaj lom thiab tsis muaj mob, nrog rau kev ua haujlwm zoo ib puag ncig, tsis muaj cov khoom xyaw tsim kev puas tsuaj thiab tsis muaj kev cuam tshuam rau ib puag ncig;

9. Nws tsis yooj yim rau tev tawm thiab muaj nqi kho mob tsawg. Vim tias cov khoom siv magnesium calcium cib muaj zog, nws tsis yooj yim rau tev tawm thiab tsis muaj nqi kho.

Cov khoomDaim ntawv thov

Magnesia calcium bricks yog siv dav hauv kev lag luam sib txawv. Cov ntawv thov kev lag luam tseem ceeb yog raws li hauv qab no:
