Hydroxypropyl starch ether rau kev tsim kho

Hydroxypropyl Starch Ether (HPS) yog cov hmoov txhuv nplej siab hloov kho uas siv hauv kev tsim kho kev lag luam ua cov thickener, binder, thiab dej-retention agent. HPS yog tsim los ntawm kev kho pob kws hmoov txhuv nplej siab nrog hydroxypropyl pawg, uas muab nws cov khoom tshwj xeeb uas ua rau nws muaj txiaj ntsig hauv ntau yam kev siv.

Ib qho ntawm cov kev siv tseem ceeb ntawm HPS hauv kev tsim kho yog ua cov thickener. HPS muaj cov khoom thickening zoo heev thiab tuaj yeem siv los ua kom cov viscosity ntawm aqueous suspensions, xws li xim, nplaum, thiab mortars. Qhov kev txhim kho viscosity no tuaj yeem pab txhim kho kev ua haujlwm thiab kev sib kis ntawm cov khoom no, ua rau lawv yooj yim rau kev thov thiab siv.

HPS kuj tseem siv los ua cov ntaub ntawv hauv kev tsim kho. Nws tuaj yeem pab txhim kho lub zog cohesive ntawm cov ntaub ntawv, xws li mortars, adhesives, thiab grouts. Qhov kev txhim kho cohesive lub zog tuaj yeem pab txhim kho tag nrho cov kev ua tau zoo ntawm cov khoom no, ua rau lawv ruaj khov dua thiab tiv taus tawg, shrinkage, thiab lwm yam degradation.

HPS kuj tseem siv los ua tus neeg saib xyuas dej hauv kev tsim kho. Nws tuaj yeem pab txhim kho cov dej tuav ntawm mortars, adhesives, thiab grouts, pab txhim kho lawv kev ua haujlwm thiab kev ua haujlwm tag nrho. Qhov kev txhim kho dej khaws cia no kuj tseem tuaj yeem pab txo qis kev pheej hmoo ntawm kev tawg thiab shrinkage, ua rau cov khoom no ruaj khov thiab txhim khu kev qha.

Hauv kev xaus, HPS yog ntau yam thiab muaj txiaj ntsig zoo hauv kev tsim kho kev lag luam. Nws lub peev xwm los txhim kho cov viscosity, cohesive zog, thiab dej tuav ntawm ntau yam ntaub ntawv tsim ua rau nws yog ib qho tseem ceeb hauv kev tsim cov khoom zoo thiab txhim khu kev qha. Nws qhov yooj yim ntawm kev siv thiab kev siv nyiaj txiag ua rau nws muaj kev xaiv nrov hauv ntau hom kev siv, los ntawm cov phiaj xwm me me mus rau kev lag luam loj.
