Hydroxypropylmethylcellulose (HPMC) ke polymer e sebetsang ka bongata e sebelisoang haholo indastering ea kaho.Ke ntho e senang chefo, e sa nkheng, e tsitsitseng pH e entsoeng ka ho hlahisa lihlopha tsa hydroxypropyl le methyl ho cellulose ea tlhaho.HPMC e fumaneha ka mefuta e fapaneng ea limaraka tse nang le li-viscosity tse fapaneng, boholo ba likaroloana le li-degrees tsa substitution.Ke polymer e qhibilihang ka metsing e ka etsang li-gel ka bongata bo phahameng empa e na le phello e fokolang kapa e se nang letho ho rheology ea metsi maemong a tlaase.Sengoliloeng sena se bua ka ts'ebeliso ea HPMC linthong tse fapaneng tsa kaho.
Tšebeliso ea HPMC ho lipolasetera le ho fana
Kaho ea meaho e hloka thepa e ntlafalitsoeng ea bokaholimo ba marako, fatše le siling.HPMC e eketsoa ho gypsum le lisebelisuoa tsa plastering ho matlafatsa ts'ebetso ea tsona le ho khomarela.HPMC e ntlafatsa boreleli le botsitso ba samente le lisebelisoa tsa ho lila.E eketsa matla a ho boloka metsi a metsoako, e ba lumellang hore ba khomarele hantle maboteng a marako kapa fatše.HPMC e boetse e thusa ho thibela ho fokotseha le ho phunyeha nakong ea ho folisa le ho omisa, ho eketsa nako e telele ea ho roala.
Tšebeliso ea HPMC ka sekhomaretsi sa lithaele
Likhomaretsi tsa lithaele ke karolo ea bohlokoa ea merero ea kajeno ea kaho.HPMC e sebelisoa ho likhomaretsi tsa lithaele ho ntlafatsa ho khomarela, ho boloka metsi le ts'ebetso ea kaho.Ho kenyelletsa HPMC ho sebopeho sa sekhomaretsi ho eketsa haholo nako e bulehileng ea sekhomaretsi, ho fa ba kenyang nako e eketsehileng ea ho etsa liphetoho pele tile e beha.HPMC e boetse e eketsa ho tenyetseha le ho tšoarella ha bondline, ho fokotsa kotsi ea delamination kapa ho phunyeha.
Tšebeliso ea HPMC ka har'a metsoako ea ho ikemela
Metsoako ea ho ikemela e sebelisetsoa ho lekanya fatše le ho etsa sebaka se boreleli, se lekaneng bakeng sa ho kenya lisebelisoa tsa fatše.HPMC e eketsoa ho metsoako ea ho ikemela ho ntlafatsa phallo ea eona le thepa ea ho lekanya.HPMC e fokotsa viscosity ea pele ea motsoako, e etsa hore ho be bonolo ho e sebelisa le ho ntlafatsa boemo.HPMC e boetse e eketsa ho boloka metsi a motsoako, ho netefatsa matla a matle a tlamahano pakeng tsa thepa ea fatše le substrate.
Tšebeliso ea HPMC ka caulk
Grout e sebelisetsoa ho tlatsa likheo pakeng tsa lithaele, lejoe la tlhaho kapa lisebelisoa tse ling tsa fatše.HPMC e kenyellelitsoe komporong e kopaneng ho ntlafatsa ts'ebetso ea eona ea kaho le ho tšoarella.HPMC e eketsa viscosity ea motsoako, ho etsa hore ho be bonolo ho jala le ho fokotsa ho fokotseha le ho phunyeha ha thepa ea ho tlatsa nakong ea ho phekola.HPMC e boetse e ntlafatsa ho khomarela ha filler ho substrate, ho fokotsa menyetla ea likheo le mapetsong a nakong e tlang.
HPMC ka lihlahisoa tse thehiloeng ho gypsum
Lihlahisoa tse thehiloeng ho Gypsum, tse kang plasterboard, lithaelese tsa siling le liboto tsa ho pata, li sebelisoa haholo indastering ea kaho.HPMC e sebelisoa lihlahisoa tse thehiloeng ho gypsum ho ntlafatsa ts'ebetso ea tsona, ho beha nako le matla.HPMC e fokotsa tlhokahalo ea metsi ea tlhahiso, e lumellang hore ho be le lintho tse tiileng tse phahameng, tse eketsang matla le ho tšoarella ha sehlahisoa se felileng.HPMC e boetse e ntlafatsa ho khomarela pakeng tsa likaroloana tsa gypsum le substrate, ho netefatsa tlamo e ntle.
ha re phethela
Hydroxypropylmethylcellulose (HPMC) ke polymer e sebetsang ka bongata e sebelisoang mefuteng e mengata ea thepa ea kaho.HPMC e ntlafatsa ts'ebetso ea lisebelisoa tsa gypsum le plastering, li-adhesives tsa lithaele, metsoako ea ho ikemela, li-grouts le lihlahisoa tse thehiloeng ho gypsum.Ho sebelisa HPMC ho lisebelisoa tsena ho ntlafatsa ts'ebetso, ho khomarela, ho boloka metsi le ho tšoarella.Kahoo, HPMC e thusa ho theha thepa ea moaho e matla, e tšoarellang haholoanyane, e tšoarellang nako e telele e fihlelang litlhoko tse phahameng tsa meaho ea sejoale-joale.
