Cov ntsiab lus tseem ceeb hais txog Raw Material Proportions Thiab Post-Molding Sib Tsoo Hauv Kev Tsim Cov Khoom Siv Ua Haujlwm

Cov txheej txheem tsim khoom rau pob zeb railings suav nrog ob peb kauj ruam tseem ceeb. Nws pib nrog kev npaj cov ntaub ntawv raw- feem ntau yog cement, xuab zeb, aggregate, steel reinforcement, thiab dej. Cov ntaub ntawv no yuav tsum tau muab faib ua qhov tseeb raws li qhov kev tsim kho lub zog thiab kev ua haujlwm tshwj xeeb; yam xws li cov cement lub zog qib thiab cov xuab zeb qhov zoo ntawm modulus cuam tshuam qhov sib tov sib xyaw. Tom ntej no los txog rau theem tsim thiab kev npaj, qhov twg cov railing qhov ntev, cov duab, thiab cov qauv txiav txim siab raws li daim ntawv thov thiab cov kev xav tau tshwj xeeb.

Cov txheej txheem ntau lawm ua raws li. Thawj kauj ruam yog kev tsim pwm, qhov twg pwm tsim los ua kom tau raws li cov qauv tsim, kom ntseeg tau tias qhov ntev thiab qhov chaw du. Qhov thib ob yog kev sib xyaw: cov khoom siv raw tau muab sib xyaw kom huv si hauv lub tshuab tov khoom kom ntseeg tau tias muaj kev sib haum xeeb. Qhov thib peb yog casting, qhov twg cov pob zeb sib xyaw yog nchuav rau hauv cov pwm thaum cov hlau txuas ntxiv los txhim kho cov qauv kev ua haujlwm; saib xyuas thaum lub sijhawm no los tiv thaiv kev tsim cov voids los yog cua npuas. Plaub yog molding, qhov twg cov pob zeb yog compacted thiab zoo li tus -feem ntau los ntawm kev vibration- kom ntseeg tau tias ntom. Qhov no yog ua raws li kev kho, txheej txheem ua raws li kev tswj xyuas qhov kub thiab txias kom tso cai rau lub railing kom ua tiav nws lub zog tsim. Thaum kawg, lub railing undergoes sib tsoo thiab xov kom paub meej ib tug du, aesthetically pleasing nto. Kev tswj xyuas nruj nruj yog tswj hwm ntawm txhua theem ntawm cov txheej txheem los lav qhov zoo ntawm cov pob zeb ua tiav tiav.
