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 tlase. 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 holim'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 mofuteng oa sekhomaretsi ho eketsa haholo nako e bulehileng ea sekhomaretsi, ho fa li-installers 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 phatloha.
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, e 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 lumella 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.
