Hydroxypropyl hmoov txhuv nplej siab ether(HPS) yog ib hom hmoov txhuv nplej siab ether tau los ntawm cov hmoov txhuv nplej siab, xws li pob kws, qos yaj ywm, lossis tapioca starch. Nws yog dav siv nyob rau hauv kev tsim kho kev lag luam raws li ib tug additive nyob rau hauv ntau yam tsev ntaub ntawv vim nws cov yam ntxwv tshwj xeeb. Nov yog saib lub luag haujlwm ntawm hydroxypropyl starch ether hauv kev tsim kho:

1. Kev tuav dej: HPS ua haujlwm ua tus neeg saib xyuas dej hauv cov khoom siv, xws li cement-based mortars, grouts, thiab gypsum-based khoom. Nws pab txhim kho kev ua haujlwm thiab sib xws ntawm cov ntaub ntawv no los ntawm kev txo cov dej poob thaum sib tov, thov, thiab kho. Qhov kev ncua sij hawm khaws dej no tso cai rau kom muaj dej zoo dua ntawm cov cementitious binders, uas ua rau kev txhim kho lub zog thiab ua haujlwm ntev ntawm cov khoom kawg.
2. Txhim Kho Kev Ua Haujlwm Zoo: HPS txhim kho kev ua haujlwm thiab tuav cov yam ntxwv ntawm cov khoom siv. Los ntawm kev ua kom cov cohesiveness thiab plasticity ntawm cementitious mixes, nws yooj yim dua sib tov, siv, thiab siv cov mortars thiab grouts. Qhov kev ua haujlwm tau zoo dua no ua rau kev ua kom zoo dua ntawm qhov chaw tiav thiab muab tso rau ntawm cov khoom siv ntau dua.
3. Txhim kho Adhesion: HPS tuaj yeem txhim kho qhov adhesion ntawm cov khoom siv thiab cov substrates. Thaum ntxiv rau cov nplais nplaum, ua rau, lossis plaster txheej, nws txhawb kev sib raug zoo rau ntau qhov chaw, suav nrog pob zeb, masonry, ntoo, thiab gypsum boards. Txhim kho adhesion ua kom muaj kev ruaj khov thiab ruaj khov, txo qhov kev pheej hmoo ntawm delamination lossis tsis ua haujlwm dhau sijhawm.
4. Txo Sagging thiab Slump: HPS ua raws li kev hloov kho rheology, pab tswj qhov ntws thiab sib xws ntawm cov khoom siv. Los ntawm kev muab tus cwj pwm shear-thinning, nws txo qis sagging thiab slump nyob rau hauv ntsug los yog overhead daim ntaub ntawv, xws li pobzeb installation, renders, thiab stucco coatings. Cov cuab yeej thixotropic no ua kom muaj kev ruaj ntseg zoo dua thiab tiv thaiv deformations thaum siv thiab kho.
5. Kev Tiv Thaiv Kev Txhaum Cai: HPS tuaj yeem pab txo qis qhov tshwm sim ntawm kev tawg hauv cov ntaub ntawv cementitious. Los ntawm kev txhim kho lub cohesiveness thiab tensile lub zog ntawm mortar thiab pob zeb sib tov, nws yuav pab kom txo tau shrinkage cracking thiab nto defects. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas muaj kev ncaj ncees thiab kav ntev yog qhov tseem ceeb, xws li hauv kev kho vaj tse thiab kho kom zoo nkauj tiav.
6. Compatibility nrog Additives: HPS yog sib xws nrog ntau yam ntawm lwm yam additives feem ntau siv nyob rau hauv cov ntaub ntawv siv, xws li cua-entraining agents, plasticizers, thiab mineral additives. Nws tuaj yeem yooj yim muab tso rau hauv cov formulations yam tsis muaj kev cuam tshuam rau kev ua haujlwm lossis cov khoom ntawm lwm cov khoom, kom muaj kev ruaj ntseg thiab sib xws.
7. Environmental Sustainability: HPS yog muab los ntawm cov hmoov txhuv nplej siab txuas ntxiv thiab biodegradable, ua rau nws xaiv ib puag ncig zoo rau kev tsim kho. Nws tuaj yeem pab txo qis ib puag ncig hneev taw ntawm kev tsim kho cov phiaj xwm los ntawm kev hloov cov khoom siv hluavtaws nrog lwm yam ntuj tsim.

hydroxypropyl starch ether plays lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm, kev ua haujlwm, thiab ua haujlwm ntev ntawm cov khoom siv. Nws cov dej tuav, txhim kho adhesion, rheology tswj, thiab kev tiv thaiv kev tawg ua rau nws muaj txiaj ntsig zoo ntxiv hauv ntau daim ntawv thov hauv tsev, pab txhawb rau qhov zoo thiab kev ua haujlwm ntev ntawm cov qauv tsim.
