HydroxyPropyyl methylcellueculose (HPMC) yog cov khoom siv tseem ceeb hauv phab ntsa ua kom muaj zog, ua rau nws cov nplaum thiab cov khoom sib xyaw. Nrog nws cov yam ntxwv muaj peev xwm, HPMC txhim kho kev ua yeeb yam thiab kev ua haujlwm ntawm phab ntsa uas muaj ntau yam kev tsim kho.
Phab ntsa Putty Service ua cov khoom tseem ceeb uas yog cov khoom tseem ceeb rau sab hauv thiab sab nraud, muab txoj kev du thiab ruaj khov rau kev pleev xim. HPMC ua si piv lub luag haujlwm nyob rau hauv kev ua kom zoo thiab ntev ntawm qhov kawg ua tiav los ntawm kev ua kom muaj ntau tus cwj pwm rau cov putty.
Ib qho ntawm cov haujlwm tseem ceeb ntawm HPMC hauv Phab Ntsa Putty yog nws lub luag haujlwm ua tus neeg saib xyuas tuab. Los ntawm kev ua kom zoo siv cov putty, HPMC pab tswj nws ib txwm, tiv thaiv sagging lossis dripping thaum lub sijhawm thov. Qhov no ua kom cov kev pab cuam tsis zoo sib xws thiab adhesion rau lub substrate, uas ua rau lub ntsej muag sib luag.
HPMC txhim kho lub peev xwm kav dej ntawm phab ntsa putty. Cov cuab yeej no yog tau txais txiaj ntsig tshwj xeeb thaum lub sij hawm kho tau, raws li qeeb qeeb ntawm cov dej evaporation los ntawm lub putty ntawm lub putty, tso cai rau kev siv dej thiab kho kom txaus. Kev haus dej kom zoo yog qhov tseem ceeb rau kev txhim kho lub zog thiab kav nyob rau hauv cov txheej putty, yog li kev txhim kho nws cov kev ua tau zoo thiab ntev.
Ntxiv nrog rau nws cov thickening thiab dej khaws cov khoom, HPMC tseem ua rau muaj kev ua haujlwm ntawm phab ntsa putty. Lub xub ntiag ntawm HPMC cov ntaub ntawv yooj yim thiab nthuav tawm ntawm lub putty mus rau ntau qhov chaw, ua rau cov neeg ua haujlwm zoo thiab txo qis kev siv zog los ntawm tus neeg thov. Qhov kev tsim khoom lag luam no thiab ua haujlwm tau thaum lub sijhawm tsim kho lossis kev kho dua tshiab.
HPMC AIDS hauv kev txhim kho cov nplaum ntawm phab ntsa ua kom sib txawv, suav nrog cov pob zeb ua, Masonry, Plaster, thiab ntoo. Los ntawm kev sib sau ua kom muaj zog nrog lub substrate, HPMC pab tiv thaiv kom tsis taus lub sijhawm, yog li txhim kho lub sijhawm ruaj khov thiab muaj kev ntseeg tau ntawm cov chaw tiav.
HPMC imparts thixotropic cov khoom rau phab ntsa putty, txhais tau tias lub viscosity ntawm shear kev nyuaj siab, xws li thaum daim ntawv thov, thiab nce ntxiv thaum muaj kev ntxhov siab. Qhov kev coj ua thixotropic no tau yooj yim thiab nthuav tawm ntawm lub putty thaum tiv thaiv kev swb lossis sagging ntawm qhov chaw ntsug.
HydroxyPropyyl methylcellueculose (HPMC) yog qhov tseem ceeb ntxiv rau hauv phab ntsa Putty, ua haujlwm, kev ua haujlwm, khoom noj khoom haus, kua nplaum, thiab thixotropic. Los ntawm kev sib xyaw HPMC rau hauv Phab Ntsa Putty formulations, cov chaw tsim khoom tuaj yeem txhim kho cov khoom kawg, ua tiav cov kev xav tau ntawm kev ua haujlwm zoo.
