Rau lub tshuab rwb thaiv tsev sab nraud, feem ntau nws muaj cov tshuaj nplaum sib txuas ntawm lub rooj tsavxwm rwb thaiv tsev thiab cov tshuaj nplaum uas tiv thaiv qhov chaw ntawm lub rooj tsavxwm rwb thaiv tsev. Cov tshuaj nplaum sib txuas zoo yuav tsum yooj yim rau do, yooj yim rau kev siv, tsis lo rau riam, thiab muaj cov nyhuv tiv thaiv kev poob qis, kev nplaum zoo thaum pib thiab lwm yam.
Cov tshuaj nplaum sib txuas thiab plastering xav tau cellulose kom muaj cov yam ntxwv hauv qab no: encapsulation zoo thiab ua haujlwm tau rau cov fillers; ib qho kev nkag mus rau hauv huab cua, uas tuaj yeem ua rau kom cov zis ntawm cov tshuaj nplaum; lub sijhawm ua haujlwm ntev; zoo tiv thaiv kev qaug zog Thiab lub peev xwm ntub rau ntau qhov chaw sib txawv; qhov ruaj khov ntawm slurry yog qhov zoo, thiab qhov sib xws ntawm cov slurry sib xyaw tau khaws cia ntev. Shandong "Chuangyao" hom hydroxypropyl methylcellulose tuaj yeem ua tau raws li qhov xav tau yooj yim ntawm kev sib txuas thiab plastering mortar daim ntawv thov.
Hydroxypropyl methylcellulose muaj kev ua tau zoo ntawm kev tuav dej hauv kev sib txuas thiab plastering mortar. Kev tuav dej ntau tuaj yeem ua rau cov cement hydrate tag nrho, ua rau lub zog sib txuas ntau ntxiv, thiab tib lub sijhawm, nws tuaj yeem txhim kho lub zog tensile thiab lub zog shear. Txhim kho cov txiaj ntsig ntawm kev tsim kho thiab txhim kho kev ua haujlwm zoo.
Hydroxypropyl methylcellulose ua lub luag haujlwm tseem ceeb hauv kev sib txuas thiab ua kom muaj zog ntxiv rau cov khoom siv rwb thaiv tsev thermal, ua rau cov mortar yooj yim rau txheej, txhim kho kev ua haujlwm zoo, thiab tiv taus kev sag. Lub sijhawm ua haujlwm, txhim kho kev ntsws thiab kev tawg tsis kam, txhim kho qhov zoo ntawm qhov chaw, txhim kho lub zog sib txuas.
Hauv dej lossis lwm yam kua nruab nrab, hydroxypropyl methylcellulose tuaj yeem tawg ua tej daim me me, dai rau hauv cov kua nruab nrab thiab yaj, yam tsis ua rau muaj nag thiab agglomeration, thiab muaj cov colloid tiv thaiv thiab stabilizing effects. Yao lub tuam txhab tuaj yeem kho cov txheej txheem ntau lawm thiab tswj lub sijhawm viscosity raws li cov neeg siv khoom xav tau.
