HPMC (Hydroxypropyl Methylcellulose)yog cov dej-soluble modified cellulose derivative dav siv nyob rau hauv kev tsim kho kev lag luam, tshwj xeeb tshaj yog nyob rau hauv mortars, coatings thiab adhesives. Nws lub luag haujlwm hauv cov tshuab txau tshuaj txau yog qhov tseem ceeb tshwj xeeb, vim tias nws tuaj yeem txhim kho kev ua haujlwm ntawm cov mortar, txhim kho adhesion, txhim kho fluidity thiab txuas ntxiv lub sijhawm qhib.
1. Txhim kho qhov fluidity thiab kev tsim kho ntawm mortar
Ib qho ntawm cov haujlwm tseem ceeb tshaj plaws ntawm HPMC yog txhawm rau txhim kho qhov fluidity ntawm mortar. Txij li thaum HPMC muaj cov dej solubility zoo, nws tuaj yeem tsim cov tshuaj colloidal hauv cov tshuaj khib nyiab, ua kom muaj qhov sib xws ntawm cov mortar, thiab ua kom nws zoo ib yam thiab du thaum lub sijhawm tsim kho. Qhov no yog ib qho tseem ceeb heev rau cov txheej txheem txau tshuab, uas yuav tsum tau muaj qee yam fluidity ntawm mortar thiaj li yuav tsum tau txau rau ntawm phab ntsa nrog lub siab siab hauv cov cuab yeej txau. Yog hais tias qhov fluidity ntawm lub mortar tsis txaus, nws yuav ua rau muaj teeb meem hauv kev txau, cov tshuaj tsuag tsis sib xws, thiab txawm tias clogging ntawm lub nozzle, yog li cuam tshuam rau kev tsim kho thiab kev ua haujlwm zoo.
2. Txhim kho qhov adhesion ntawm mortar
HPMC muaj cov khoom sib txuas zoo thiab tuaj yeem txhim kho qhov adhesion ntawm mortar thiab txheej txheej. Nyob rau hauv cov tshuaj tsuag tshuaj mortar, zoo adhesion yog ib qho tseem ceeb heev, tshwj xeeb tshaj yog thaum lub txheej yog siv rau facades los yog lwm yam substrates.AnxinCel®HPMCtuaj yeem txhim kho qhov adhesion ntawm mortar rau lub hauv paus nto thiab txo cov teeb meem los ntawm ib puag ncig (xws li kub thiab av noo hloov). Nyob rau tib lub sijhawm, HPMC tuaj yeem txhim kho kev sib raug zoo ntawm mortar thiab lwm yam ntaub ntawv kom tsis txhob cuam tshuam cov txheej txheem los ntawm kev sib txawv ntawm kev sib raug zoo.
3. Ntxiv cov sij hawm qhib thiab tswj kev tsim kho
Hauv kev tsim kho tshuab tshuaj tsuag, txuas ntxiv lub sijhawm qhib ntawm mortar yog qhov tseem ceeb rau kev tsim kho kom zoo. Lub sijhawm qhib yog hais txog lub sijhawm txij li thaum lub mortar siv rau saum npoo kom txog thaum nws qhuav, thiab feem ntau xav kom tus neeg ua haujlwm tsim kho tuaj yeem hloov kho, txiav thiab hloov kho thaum lub sijhawm no yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm mortar. HPMC tuaj yeem txuas ntxiv lub sijhawm qhib los ntawm kev ua kom cov viscosity ntawm cov mortar thiab txo cov evaporation ntawm cov dej. Qhov no tso cai rau lub sprayer ua hauj lwm ntev dua thiab tsis txhob muaj cov kab nrib pleb los yog tsis sib xws los ntawm kev ziab sai heev.
4. Tiv thaiv delamination thiab nag lossis daus
Hauv kev siv tshuaj tsuag tshuaj mortar, vim yog kev thauj mus los ntev thiab khaws cia, cov nag lossis daus tuaj yeem tshwm sim hauv mortar, ua rau mortar delamination. HPMC muaj lub zog ncua kev kawm ntawv, uas tuaj yeem tiv thaiv cov khoom zoo lossis lwm yam khoom siv hauv lub mortar los ntawm kev daws thiab tswj qhov sib xws ntawm cov mortar. Qhov no feature yog tshwj xeeb tshaj yog ib qho tseem ceeb los xyuas kom meej cov nyhuv spraying thiab mortar zoo. Tshwj xeeb tshaj yog nyob rau hauv kev tsim kho loj, kev tswj xyuas qhov sib xws thiab kev ruaj ntseg ntawm cov mortar yog tus yuam sij kom ntseeg tau tias kev tsim kho zoo.
5. Txhim kho cov dej khaws cia ntawm mortar
Raws li cov dej-soluble polymer compound, HPMC muaj zog tuav dej. Nws tsim ib zaj duab xis nyias nyob rau hauv mortar, yog li txo cov evaporation ntawm noo noo. Cov cuab yeej no tseem ceeb heev kom cov mortar moist thiab txo qhov tshwm sim ntawm cov kab nrib pleb. Tshwj xeeb tshaj yog nyob rau hauv high-temperature, low-humidity ib puag ncig, mortar yog nquag ziab sai heev thiab tawg. HPMC tuaj yeem txo qhov tshwm sim ntawm qhov xwm txheej no los ntawm kev txhim kho cov dej khaws cia ntawm cov mortar thiab xyuas kom meej tias cov mortar tau kho kom zoo thiab kho kom zoo nyob rau lub sijhawm tsim nyog.
6. Txhim kho qhov tawg tsis kam thiab durability ntawm mortar
Txij li thaum HPMC tuaj yeem txhim kho cov dej tuav thiab kev sib txuas ntawm cov tshuaj khib nyiab, nws tuaj yeem txhim kho qhov tawg thiab ua haujlwm ntawm cov tshuaj khib nyiab. Thaum lub sij hawm cov txheej txheem tshuaj tsuag, lub uniformity thiab stability ntawm lub mortar txheej yog ib qho tseem ceeb heev rau lub sij hawm ntev ntawm kev tawg. Los ntawm kev txhim kho cov cohesion thiab nto adhesion ntawm lub mortar, AnxinCel®HPMC zoo txo qhov kev pheej hmoo ntawm cov kab nrib pleb tshwm sim los ntawm kev hloov kub, kev sib haum xeeb los yog lwm yam sab nraud, thiab txuas ntxiv lub neej kev pab cuam ntawm lub mortar.
7. Txhim kho qhov yooj yim thiab ruaj khov ntawm kev ua haujlwm txau
Thaum siv cov cuab yeej siv tshuaj tsuag rau kev tsim kho, qhov fluidity, viscosity thiab stability ntawm lub mortar yog qhov tseem ceeb rau kev ua haujlwm ntawm cov khoom siv. HPMC txo cov khoom siv tshuaj tua kab mob thiab cov kev xav tau kev saib xyuas los ntawm kev txhim kho cov kua dej thiab ruaj khov ntawm cov tshuaj khib. Nws kuj tseem tuaj yeem txo qhov teeb meem ntawm mortar deposition los yog clogging nyob rau hauv cov cuab yeej, kom ntseeg tau tias cov cuab yeej ib txwm tuav ruaj khov nyob rau hauv lub sij hawm ntev kev tsim kho txheej txheem.
8. Txhim khu kev ua qias tuaj ntawm mortar
HPMCmuaj zog tiv thaiv kev ua qias tuaj. Nws tuaj yeem tiv thaiv qhov adhesion ntawm cov khoom tsis zoo lossis cov pa phem hauv cov mortar thiab tswj kev huv ntawm cov tshuaj khib. Tshwj xeeb tshaj yog nyob rau qee qhov chaw tshwj xeeb, mortar tau yooj yim cuam tshuam los ntawm cov pa phem sab nraud. Qhov sib ntxiv ntawm HPMC tuaj yeem cuam tshuam qhov adhesion ntawm cov pa phem no, yog li ua kom muaj kev tsim kho zoo thiab zoo li qub.
Lub luag hauj lwm ntawm HPMC nyob rau hauv mechanical spray mortar yog multifaceted. Nws tuaj yeem tsis tsuas yog txhim kho cov dej ntws thiab kev tsim kho ntawm mortar, tab sis kuj txhim kho adhesion, txuas ntxiv lub sijhawm qhib, txhim kho cov dej tuav, txhim kho kev sib tsoo thiab txhim kho kev muaj peev xwm tiv thaiv, thiab lwm yam. Los ntawm kev sib ntxiv ntawm HPMC, tag nrho cov kev ua tau zoo ntawm mortar tuaj yeem ua kom zoo dua qub, ua kom muaj kev ruaj ntseg thiab siv sij hawm ntev ntawm cov tshuaj khib nyiab thaum lub sij hawm tsim kho. Yog li ntawd, HPMC yog dav siv nyob rau hauv niaj hnub tsim tsev, tshwj xeeb tshaj yog nyob rau hauv mechanical spray mortar, qhov twg nws plays ib tug irreplaceable thiab tseem ceeb luag hauj lwm.
