Qhuav mortar yog ntau yam khoom siv hauv tsev thiab nrov siv hauv ntau yam kev siv, los ntawm bricklaying thiab thaiv nteg rau pobzeb inlay thiab veneer. Txawm li cas los xij, kev ua haujlwm ntev ntawm cov tshuaj khib nyiab tuaj yeem ua rau muaj kev txhawj xeeb rau ntau tus neeg tsim thiab cov tswv tsev, vim tias nws yuav ua rau tawg, tshwj xeeb tshaj yog nyob rau hauv huab cua hnyav.
Hmoov zoo, muaj ntau txoj kev daws teeb meem los txhim kho lub zog thiab tawg tsis kam ntawm cov tshuaj khib nyiab qhuav, ib qho kev daws teeb meem zoo tshaj plaws yog kev siv hydroxypropyl methylcellulose (HPMC).
HPMCs yog dab tsi?
HPMC yog ib qho hluavtaws polymer uas tsim los ntawm kev hloov tshuaj lom neeg ntawm ntuj cellulose. Nws yog feem ntau siv nyob rau hauv kev tsim kho kev lag luam raws li ib tug binder thiab thickener nyob rau hauv qhuav mix xws li qhuav mortar.
HPMC yog dej soluble heev thiab tsim cov khoom zoo li gel thaum sib xyaw nrog lwm cov khoom xyaw. Nws kuj yog non-toxic, non-irritating thiab biodegradable, ua rau nws muaj kev nyab xeeb thiab ib puag ncig tus phooj ywg lub tsev khoom additive.
HPMC ua li cas txhim kho cov kav ntev thiab tawg tsis kam ntawm cov tshuaj khib nyiab qhuav?
1. Txhim kho dej tuav
Ib qho txiaj ntsig tseem ceeb ntawm HPMC hauv cov mortars qhuav yog nws lub peev xwm los ua kom cov dej tuav tau. Thaum sib xyaw nrog dej, HPMC tsim cov khoom zoo li gel uas pab ua kom cov dej sib xyaw kom ntev dua. Qhov no ua rau muaj kev sib xyaw ua ke ntau dua thiab homogeneous sib xyaw uas tsis tshua muaj kev tawg lossis tawg hauv qhov siab.
Kev txhim kho dej tuav kuj tseem pab txhim kho kev ua haujlwm tag nrho ntawm cov mortar, ua kom yooj yim rau kev thov thiab muab nws ib qho smoother, zoo ib yam.
2. Txhim kho adhesion
Lwm qhov zoo dua ntawm HPMC hauv mortar qhuav yog nws lub peev xwm los txhim kho adhesion. HPMC ua raws li ib tug binder, pab khi cov sib tov ua ke thiab ua raws li nws mus rau saum npoo nws yog siv rau.
Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas mortar yog siv los tuav cov vuas, cib los yog blocks nyob rau hauv qhov chaw vim nws pab tiv thaiv kev txav los yog hloov.
3. Txhim kho kev ua haujlwm
Ntxiv nrog rau kev txhim kho cov dej tuav thiab adhesion, HPMC tseem tuaj yeem txhim kho kev ua haujlwm tag nrho ntawm cov mortars qhuav. Los ntawm kev ntxiv HPMC rau qhov sib tov, cov neeg cog lus thiab cov neeg tsim khoom tuaj yeem ua tiav qhov sib xyaw ua ke thiab homogeneous ntau dua uas yooj yim rau kev thov thiab cov duab.
Qhov no yuav pab txo qhov kev pheej hmoo ntawm kev tawg lossis tawg thaum lub sij hawm thov thiab txhim kho qhov kawg ntawm cov khoom tiav.
4. Ntxiv dag zog
Thaum kawg, HPMC tau pom tias ua kom lub zog tag nrho thiab ua haujlwm ntev ntawm cov mortars qhuav. Qhov no yog vim kev txhim kho dej tuav thiab adhesion, uas ua rau kom muaj kev ruaj khov thiab muaj kev nyab xeeb dua.
Los ntawm kev siv HPMC hauv mortar qhuav, cov neeg tsim khoom tuaj yeem tsim cov khoom lag luam txhim khu kev qha, ruaj khov uas tsis tshua muaj kev tawg lossis tawg thaum lub sijhawm.
nyob rau hauv xaus
Hauv kev xaus, HPMC yog qhov muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo ntxiv los txhim kho cov kav ntev thiab tawg tsis kam ntawm cov mortars qhuav. Nws txhim kho cov dej tuav, adhesion, kev ua haujlwm thiab lub zog, ua rau nws zoo tagnrho rau cov neeg cog lus thiab cov neeg tsim khoom nrhiav kev tsim cov khoom lag luam txhim khu kev qha thiab kav ntev.
Los ntawm kev siv HPMC hauv cov tshuaj khib nyiab qhuav, cov neeg tsim khoom tuaj yeem ua kom lawv cov haujlwm ruaj khov, nrog kev sib raug zoo, txawm tias ua tiav uas tsis tshua muaj kev tawg lossis tawg dhau sijhawm. Yog li lwm zaus koj tab tom ua haujlwm ntawm kev tsim kho, xav txog kev siv HPMC los txhim kho qhov zoo thiab ruaj khov ntawm koj cov mortar qhuav.
