Vim li cas ho tsis tau quartz pob zeb yuav nkaug nrog cement

Raws li lub hom phiaj ntawm kev noj qab haus huv thiab cov khoom noj khoom haus zoo tshaj plaws uas ua raws li kev tsim kho lub teb chaws txoj kev lag luam, quartz pob zeb tau nkag mus rau hauv kev ua lag luam hauv xyoo 1980s. Nrog lub nruam li ntawm qhov muaj peev xwm thiab kev tshawb nrhiav thiab kev loj hlob muaj peev xwm ntawm quartz pob zeb cov tuam txhab nyob rau hauv Suav teb, daim ntawv thov ntawm artificial quartz pob zeb nyob rau hauv lub tshav pob ntawm zoo nkauj pob zeb ntau thiab ntau kim heev. Thiab yog dav siv nyob rau hauv ntau qhov chaw hauv tsev sab hauv.

Txog kev siv quartz pob zeb hauv thaj chaw ntawm cov hniav zoo nkauj, kev lag luam tus qauv tsim los ntawm National Building Materials Testing Center - JG / T 463--2014 "Artificial Quartz Slab rau Tsev Kho Kom Zoo Nkauj" tau raug pom zoo rau cov ntawv luam tawm thiab tau luam tawm nyob rau xyoo 2015. Nws tau ua tiav raws li lub Tsib Hlis 1. Cov txheej txheem no muaj ib lub luag haujlwm tseem ceeb hauv kev tswj cov khoom zoo ntawm quartz pob zeb, tsim qauv thiab coj cov ntaub ntawv kom zoo ntawm cov quartz pob zeb, thiab tau muab cov qauv zoo rau cov qauv siv zeb ua qauv. Quartz cov qauv siv zeb tsim kuj txawv txav rau ntau tus neeg. Hnub no peb yuav tawm tswv yim seb vim li cas cov maas yuav siv tsis tau los ua cov quartz.

Feem ntau cov tsev kho dua tshiab siv cov cement rau paste pem teb. Maas thiab quartz pob zeb muab tshuaj txhuam, feem ntau dhau sijhawm, xis mas thiab quartz yuav cais. Yog vim li cas yog tias cov kev ntxhib los mos ntawm cov pob zeb quartz thiab cov vuas ntaub pua tsev yog txawv. Vim hais tias cov xis mas yog tsis muaj zog alkaline, nws tuaj yeem nrog cov kua qaub, raws li lub quartz pob zeb phaj raw khoom muaj acidic cob. Lub alkali nyob rau hauv lub cement reacts sib xws nrog cov kua qaub nyob hauv daim duab. Quartz zeb pem teb muab tshuaj yuav tsum tau siv rau qhov ceev-ziab nruab nrab cov nplaum lossis cov kua nplaum tshwj xeeb thaum tso.
