Hydroxypropyl starch yog cov hmoov txhuv nplej siab hloov kho uas muaj cov ntawv thov hauv ntau qhov kev lag luam, suav nrog kev tsim kho kev lag luam rau kev siv tshuaj khib nyiab.Mortar yog kev sib xyaw ntawm cov cement, xuab zeb thiab dej siv los khi lub tsev thaiv xws li cib lossis pob zeb.Ntxiv hydroxypropyl starch rau mortar pab ntau lub hom phiaj thiab txhim kho nws cov kev ua tau zoo hauv kev tsim kho.
Nov yog qee qhov tseem ceeb ntawm hydroxypropyl starch rau mortar:
Kev tuav dej: Hydroxypropyl starch ua raws li tus neeg saib xyuas dej hauv mortar.Nws pab txo cov dej evaporation thaum lub sijhawm kho, kom ntseeg tau tias cov tshuaj khib nyiab khaws cov dej noo txaus.Qhov no yog qhov tseem ceeb rau kev hydration ntawm cov cement, yog li ua kom lub zog thiab durability ntawm mortar.
Txhim kho kev ua haujlwm: Qhov sib ntxiv ntawm hydroxypropyl hmoov txhuv nplej siab txhim kho kev ua haujlwm ntawm mortar.Nws txhim kho qhov sib xws thiab yooj yim ntawm daim ntawv thov, ua rau kom zoo dua adhesion rau lub tsev.Qhov no yog qhov tseem ceeb tshwj xeeb ntawm kev tsim kho cov haujlwm uas yooj yim ntawm kev tuav thiab siv cov tshuaj khib nyiab yog qhov tseem ceeb.
Teem sijhawm tswj: Hydroxypropyl hmoov txhuv nplej siab yuav cuam tshuam rau lub sijhawm teeb tsa ntawm mortar.Los ntawm kev kho tus nqi ntawm hydroxypropyl hmoov txhuv nplej siab siv, cov neeg cog lus tuaj yeem tswj lub sijhawm teem sijhawm ntawm cov tshuaj khib nyiab sib tov.Qhov no yog qhov zoo nyob rau hauv ntau yam kev tsim kho qhov chaw tshwj xeeb lub sijhawm yuav tsum tau ua kom pom kev ua tau zoo.
Txo Shrinkage: Shrinkage yog ib qho teeb meem tshwm sim nrog mortar thiab tuaj yeem ua rau tawg ntawm cov qauv tiav.Hydroxypropyl hmoov txhuv nplej siab pab txo qis qis los ntawm kev txo cov dej noo thaum kho.Qhov no pab txhim kho lub zuag qhia tag nrho durability ntawm mortar thiab nws cov qauv txhawb.
Enhanced adhesion: Lub adhesion ntawm mortar yog qhov tseem ceeb rau kev ruaj ntseg thiab kev ua haujlwm ntev ntawm lub tsev.Hydroxypropyl hmoov txhuv nplej siab tuaj yeem txhim kho qhov adhesion ntawm mortar rau ntau yam substrates thiab muab kev sib raug zoo ntawm mortar thiab cov khoom siv hauv tsev.
Resistance to Sag: Hauv kev siv ntsug, xws li plastering lossis plastering phab ntsa, qhov kev tiv thaiv ntawm mortar rau sag yog qhov tseem ceeb heev.Hydroxypropyl hmoov txhuv nplej siab pab txhawb rau cov khoom thixotropic ntawm cov tshuaj khib nyiab, txo qhov muaj feem ntawm sagging thiab kom ntseeg tau cov tuab tuab hauv cov ntawv ntsug.
Compatibility nrog rau lwm yam additives: Hydroxypropyl starch yog feem ntau sib xws nrog lwm yam additives siv nyob rau hauv mortar formulations.Qhov no versatility tso cai rau cov neeg ua hauj lwm los txiav cov mortar sib tov rau tej yam yuav tsum tau, coj kom zoo dua ntawm cov synergies ntawm txawv additives.
Kev xav txog ib puag ncig: Cov hmoov txhuv nplej siab ntxiv, xws li hydroxypropyl hmoov txhuv nplej siab, feem ntau suav hais tias yog ib puag ncig zoo.Lawv yog biodegradable thiab muaj kev cuam tshuam ib puag ncig tsawg dua piv rau qee cov khoom siv hluavtaws.
Hydroxypropyl starch plays lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm kev tsim kho mortars.Cov txiaj ntsig suav nrog kev txhim kho dej tuav, kev ua tiav, kev tswj lub sijhawm, txo qis, txhim kho adhesion, sag resistance, compatibility nrog lwm yam additives, thiab ib puag ncig xav txog.Cov khoom no ua rau cov hmoov txhuv nplej siab hydroxypropyl muaj txiaj ntsig zoo rau kev tsim cov khoom siv hauv tsev zoo thiab ruaj khov.
