Taw qhia:
HydroxyPropyyl Metylcellulose (HPMC) yog ib qho ntau yam siv dav siv hauv kev tsim kho kom muaj kev lag luam rau nws lub peev xwm los txhim kho lub tsev ua haujlwm.
Nkag siab HydroxyPropyyl methylcellulose (HPMC):
HPMC yog qhov hluavtaws sib xyaw ua los ntawm cellulose, lub ntuj polymer pom hauv cov nroj tsuag. Nws yog tsim los ntawm kev hloov kho tshuaj lom neeg ntawm cellulose, ua rau hauv dej-soluble polymer nrog cov khoom tshwj xeeb. HPMC yog tus cwj pwm los ntawm nws cov dej kom muaj zog kom muaj peev xwm, kev sib sau ua yeeb yaj kiab, thiab adhesion zoo heev rau ntau yam substrates.
Cov cuab yeej ua haujlwm ntawm cov khoom siv tsis tau:
Dej khaws cia: Ib qho ntawm cov txheej txheem tseem ceeb uas HPMC txhim kho Durability yog nws lub peev xwm los khaws dej hauv cov ntaub ntawv tsim kho. Los ntawm kev sib sau ua yeeb yaj kiab tiv thaiv ntau tshaj li thaj chaw, HPMC txo cov dej evaporation, tiv thaiv kev ua kom qhuav thiab shrinkage. Qhov no yog tshwj xeeb yog qhov tseem ceeb hauv cov khoom siv hlwb, qhov twg txaus cov dej haus yog qhov tseem ceeb rau kev ua tiav lub zog thiab kav ntev.
Txhim kho qhov ua haujlwm: HPMC ua raws li kev kho mob rheology, txhim kho cov khoom ua haujlwm xws li mortars, thiab renders. Nws lub sijhawm muaj kev txhim kho qhov sib xws thiab kev ua tau zoo ntawm cov mixtures, cia kom muaj kev sib cais yooj yim thiab txo cov kev sib cais los yog tawg thaum lub sijhawm tso.
Txhim kho Adhesion: HPMC txhim kho cov nplaum, cov nplaum, thiab cov sealants rau substrates, yog li kev txhim kho cov nyiaj tag nrho thiab kav ntev ntawm cov kab ke no. Qhov no yog tau txais txiaj ntsig tshwj xeeb hauv kev siv daim ntawv thov pov tseg, qhov twg yog qhov tseem ceeb rau kev tiv thaiv dej infilation thiab tswj cov txheej txheem kev ntseeg siab nyob rau lub sijhawm.
Cov ntawv thov hauv cov ntaub ntawv hauv tsev:
Cov Mement-raws mortars thiab renders: HPMC yog feem ntau siv los ua kev ntxiv nyob rau hauv cov xis nyob hauv kev ua kom muaj zog thiab cov lus qhia, thiab dej khaws cia. Los ntawm kev sib txuam HPMC rau hauv cov kev sib xyaw no, cov neeg cog lus tuaj yeem ua tiav cov tiav smoother, txo cov kev tawg, thiab txhim kho kev tawg siab ntev.
Cov ntaub ntawv nplaum thiab Grouts: hauv cov ntaub ntawv txheej txheem hauv av, HPMC ntxiv rau cov nplaum thiab cov khoom lag luam kom tiv thaiv kom muaj dej ingress. Nws cov dej khaws cia kom muaj kev haus dej kom zoo, thaum nws muaj peev xwm ua yeeb yaj kiab, thaum nws muaj peev xwm ua yeeb yaj kiab, thaum nws muaj kev pheej hmoo ntawm cov pob txha toric, txo qhov kev pheej hmoo ntawm cov staining thiab tsis zoo.
Gypsum-based khoom: HPMC pom ntau yam siv hauv gypsum-based khoom xws li cov tebchaw thiab plasters. Los ntawm kev txhim kho kev ua haujlwm thiab dej khaws cia, HPMC ua rau daim ntawv thov smoother smoother
Rwb thaiv tsev sab nrauv thiab cov tshuab ua tiav tiav (EIFS): Hauv EIFS daim ntawv thov, HPMC tab tom siv los txhim kho cov tsho tiv no, cov nplaum, thiab lub tsho ntev tag nrho. Nws lub peev xwm los txhim kho adhesion, thiab tawg tawm tsam ua rau nws tsis tseem ceeb ntxiv rau kev ua tiav ntev ntev thiab ua kom zoo nkauj rau façades.
HydroxyPropyyl methylcellueculose (HPMC) plays lub luag haujlwm tseem ceeb hauv kev txhim kho lub zog ntawm cov ntaub ntawv kev tsim kho thoob plaws ntau yam kev tsim kho. Los ntawm kev siv zog nws cov yam ntxwv, suav nrog kev siv cov dej, txhim kho cov khoom tsim kho kom ua haujlwm siab, hPMC ua rau muaj kev sib tw ntawm lub sijhawm thiab kev sib tw ntawm ib puag ncig. Raws li kev tsim kho kev tsim kho txuas ntxiv mus ua ntej ua ntej kev ua kom muaj kev cia siab thiab ntev, kev thov rau HPMC-based daws teeb meem, tsav tshiab hauv kev tsim thev naus laus zis.
