LONGKETER muab ntau yam ntawmHigh Alumina Refractory Cement.

High alumina refractory cement yog calcium aluminate cement, nws tseem hu ua high alumina cement, refractory cement, calcium alumina cement.

Siab aluminarefractorycement yog txawv ntawm Portland cement, nws tsis tuaj yeem siv rau kev tsim kho pej xeem. Nws yog tsim los ntawm calcium aluminates es tsis txhob calcium silicates. Calcium carbonate thiab bauxite yog cov khoom xyaw tseem ceeb. High alumina cement yog dav siv los ua tus neeg sawv cev ntawm alumina refractory castable.

Cov txheej txheem tsim khoom: Cov khoom siv hmoov qib--kev sib xyaw--Rolling rau hauv cov khoom --- raug rho tawm haujlwm hauv qhov los yog cov ncej kilns --- clinkers sib tsoo rau hauv cov hmoov-- tshuaj xyuas thiab ntim

Ua ntej, siab alumina refractory cement muaj cov cua sov zoo heev. Nws tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj kev tawg lossis poob lub zog. Qhov no yog vim lub siab alumina refractory cement muaj ntau ntawm aluminate thiab calcium aluminate compounds. Cov ntsiab lus siab melting ntawm cov tebchaw no xyuas kom meej tias cov cement tuaj yeem tiv taus qhov kub thiab txias.

Ntxiv nrog rau qhov kub tsis kam, siab alumina refractory cement kuj muaj kev tiv thaiv corrosion siab. Nws yog resistant mus tua los ntawm ntau yam chemical agents, ua rau nws zoo tagnrho rau siv nyob rau hauv hnyav ib puag ncig uas lwm hom cement yuav ua tsis tau.

Thaum kawg, siab alumina refractory cement yog resistant rau thermal shock. Thermal shock tshwm sim thaum cov ntaub ntawv raug hloov pauv sai hauv qhov kub thiab txias. High alumina refractory cement tuaj yeem tiv taus qhov kev hloov pauv no yam tsis tau poob nws lub zog lossis kev ncaj ncees.
