Raws li cov tsev thiab cov pobzeb kev teeb tsa ua ntau dua, qhov kev xav tau ntawm cov khoom lag luam txhim khu kev qha thiab cov khoom zoo los xyuas kom meej qhov kev ua tiav yuav yog qhov tseem ceeb dua. Ib yam khoom uas yog qhov tseem ceeb hauv kev teeb tsa cov pobzeb niaj hnub yog pobzeb grout additive.
Pobzeb grout additives yog ib qho tseem ceeb muaj nyob rau hauv cov txheej txheem grouting los xyuas kom meej cov pobzeb adhesion, lub zog thiab durability. Cov additives no ua rau cov grout ntau saj zawg zog, waterproof thiab muaj zog. Tsis tas li ntawd, lawv txhim kho qhov smoothness, xim tuav thiab kev ntxhib los mos ntawm grout, ua kom yooj yim rau kev thov thiab muab qhov zoo dua.
Hydroxypropylmethylcellulose (HPMC) yog cov pobzeb grout additive uas tau txais koob meej hauv kev lag luam. HPMC yog cellulose ether ua los ntawm methylcellulose thiab propylene oxide. Nws yog dav siv nyob rau hauv kev tsim kho kev lag luam rau nws zoo heev dej tuav, thickening, coagulation thiab lwm yam khoom.
Kev siv HPMC ua cov pobzeb grout additive coj cov txiaj ntsig tseem ceeb rau kev tsim kho kev lag luam.
1. Ua ntej, HPMC yog cov dej tsis zoo, uas ua rau nws tsim nyog rau thaj chaw uas nquag raug dej, xws li chav dej, chav ua noj, thiab pas dej da dej. Nws cov khoom tuav dej kuj tseem ua kom cov pobzeb nyob ruaj ntseg hauv qhov chaw, txo qhov kev pheej hmoo ntawm dej puas thiab pwm loj hlob.
2. HPMC txhim khu lub zog thiab durability ntawm cov grout, ua rau nws muaj peev xwm tiv taus siab, cuam tshuam thiab hnav. Qhov no feature yog tshwj xeeb tshaj yog ib qho tseem ceeb nyob rau hauv kev lag luam ib puag ncig uas muaj tsheb thauj mus los siab thiab cov pobzeb siv yog siab.
3.HPMC tuaj yeem siv los ua cov nplaum rau pobzeb grout, muab kev sib koom ua ke ntau dua, sib xws thiab ruaj khov. Qhov no ua rau cov grout tswj tau yooj yim dua, siv tau yooj yim dua, thiab yuav tsum muaj kev saib xyuas tsawg dua nyob rau lub sijhawm ntev.
4. HPMC txhim kho qhov smoothness thiab kev ntxhib los mos ntawm cov grout, uas ua rau muaj kev zoo nkauj zoo nkauj dua. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv qhov chaw nyob, qhov chaw uas tus tswv tsev zoo nkauj yog qhov tseem ceeb.
Thaum kawg, HPMC yog ib puag ncig tus phooj ywg thiab biodegradable, ua rau nws muaj kev nyab xeeb rau kev siv hauv txhua qhov chaw tsim kho. Qhov no ua kom tsis muaj kev puas tsuaj rau ib puag ncig lossis cov neeg ua haujlwm tuav cov khoom.
Hauv kev xaus, kev siv cov pobzeb grout additives tau dhau los ua qhov tseem ceeb hauv kev tsim kho niaj hnub no. HPMC, tshwj xeeb, yog ib qho tseem ceeb ntawm cov pobzeb grout additive uas tuaj yeem nqa cov txiaj ntsig tseem ceeb rau cov phiaj xwm pobzeb. Nws cov dej tsis zoo, ruaj khov, nplaum thiab zoo nkauj ua rau nws zoo tagnrho rau ob qho tib si nyob hauv tsev thiab chaw lag luam. Raws li kev tsim kho kev lag luam txuas ntxiv mus, cov khoom xws li HPMC yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev vam meej ntawm kev tsim kho.
