Lwm yam kev ceev faj thaum tsim lub qhov cub tiv thaiv

(1) Nyob rau hauv cov nqe lus ntawm ambient kub, nruj me ntsis raws li qhov yuav tsum tau ntawm "Code rau kev tsim kho thiab txais ntawm Industrial rauv Masonry Engineering". Cov ntsiab lus tseem ceeb tuaj yeem tsim ua ntej, thiab ntau yam kev ntsuas tsis tuaj yeem kuaj, thiab tom qab ntawd tsim ua raws li qhov tsim nyog.

(2) Thaum ua cov phiaj xwm kho ntawm qhov chaw, qhov kev rhuav tshem yuav tsum xyuas kom meej tias qhov tsis tau kho ntawm cov masonry zoo li qub thiab tsis loosened, thiab muaj peev xwm ntawm cov masonry tsoo los yog ib tus neeg cib poob.

Lub teeb yuag refractory cib rau masonry ntawm qhov cub tsis kam

Kev siv qhov kub thiab txias ntawm cov cib refractory yuav tsum qis dua qhov kub ntawm cov cib los ntawm 70-100 degree, kom tsis txhob muaj hluav taws kub hnyiab loj thiab ua rau cib tawg thiab cib tawg. Rau cov khoom uas dais loj dua, xws li lub qhov cub hauv qab thiab lub hauv paus, siv cov av nplaum refractory. Cov cib ntawm lub qhov rooj ntawm lub thawv rauv yog yooj yim rau kev puas tsuaj vim qhov nkag thiab tawm ntawm lub workpieces.

Refractory tube rau masonry lead pas nrig ntawm kuj rauv

Cov yeeb nkab refractory rau cov pas hlau lead yuav tsum tau ua raws li lub qhov ntawm lub plhaub ntawm lub cub tawg. Yog tias qhov nruab nrab ntawm lub qhov tsis nyob ntawm qhov siab, nws yog feem ntau tuaj yeem zom tawm ntawm qhov qis ntawm cov av nplaum cib uas txhawb nqa lub tshuab hluav taws xob. Lub cub tawg hlau txee yog ua los ntawm cov khoom siv aluminium siab, thiab siab aluminium cib Fe2O3<1.5%. Iron oxide is a catalyst that promotes the carbon monoxide precipitation reaction in the atmosphere at 450-550°C. After carbon black is deposited in the brick, its volume swells, resulting in a decrease in the strength of the masonry and early failure.

Masonry cib pob qij txha ntawm cov hluav taws kub tsis kam

Lub cib sib koom ua ke yog qhov chaw tsis muaj zog tshaj plaws ntawm cov masonry, thiab nws txoj hauj lwm yuav tsum zam qhov kev ntxhov siab ntawm cov masonry, insulating cib txheej thiab lub cub tawg. Cov pob qij txha cib tau ntim nrog cov av nkos refractory, thiab thaum cov masonry qhuav yog ntim nrog cov hmoov refractory, cov refractory masonry ua tag nrho. Cov pob qij txha txuas tsis tuaj yeem nkag mus rau hauv cov masonry, tsis muaj hluav taws kub, cua nkag, thiab lwm yam, yuav tsum tau staggered nce, nqis, sab laug thiab sab xis. Sau cov pob qij txha txuas nrog refractory fibers, asbestos khoom, thiab lwm yam, thiab tsis txhob poob rau hauv av nkos, tawg cib thiab lwm yam khib nyiab. Thaum muaj cov khoom siv hlau hauv cov masonry, cov pob qij txha txuas ntxiv yuav tsum tau sab laug ntawm cov khoom siv hlau thiab cov masonry.
