Poloko ea Metsi: E 'ngoe ea thepa ea bohlokoa ea HPMC ke bokhoni ba eona ba ho boloka metsi.Lits'ebetsong tsa kaho, sena ke sa bohlokoa ho boloka ts'ebetso ea seretse le ho etsa bonnete ba hore hydration e nepahetseng ea thepa ea samente.
Thickener: HPMC ke setenya se sebetsang hantle se eketsang viscosity ea thepa ea kaho joalo ka likhomaretsi, lira tse koahelang le metsoako e kopaneng.
Ts'ebetso e ntlafetseng: HPMC e thusa ho ntlafatsa ts'ebetso le ho boloka thepa ea samente e thellang, ho etsa hore ho be bonolo ho sebetsana le ho sebetsa.
Taolo ea ho beha: E ama nako ea ho beha thepa ea samente mme e fana ka taolo e ntle holim'a ts'ebetso ea ho beha.
Tlhahiso ea Lifilimi: HPMC e etsa filimi e tšesaane, e tenyetsehang holim'a metsi, e thusang ho etsa hore pente e tšoarelle le ho thibela metsi.
Khomarelo e Ntlafetseng: E ntlafatsa ho khomarela lisebelisoa tsa mohaho, e khothalletsa maqhama a betere pakeng tsa li-substrates.
3. Tšebeliso ea HPMC kahong:
3.1 Lirafshoa le lipolasetere:
Ho Boloka Metsi: HPMC e atisa ho sebelisoa liretseng le li-plaster ho ntlafatsa ho boloka metsi, ho thibela ho omisoa pele ho nako ea motsoako le ho etsa bonnete ba hore samente e phalla ka ho feletseng.
Bokhoni ba ho sebetsa: Ho eketsoa ha HPMC ho ntlafatsa ts'ebetso ea seretse, ho etsa hore kaho le ho phethela ho be bonolo.
Adhesion: E ntlafatsa ho khomarela seretse le stucco ho li-substrates tse fapaneng, ho fella ka qetello e matla, e tšoarellang haholoanyane.
3.2 Likhomaretsi tsa lithaele le li-grouts:
Slip Resistance: Likhomaretsing tsa lithaele, HPMC e thusa ho laola khanyetso ea ho thella ho netefatsa hore tile e khomarela ka thata holimo.
Ho teteka: Joaloka moemeli oa ho teteka, HPMC e kenya letsoho ho ts'ebetsong e nepahetseng ea li-adhesive le li-grouts.
Ho boloka metsi: E thibela ho tsoa ka potlako ha metsi 'me e khothalletsa pholiso e sebetsang ea li-adhesives le grout.
3.3 Phetolelo e thehiloeng ho samente:
Crack Resistance: HPMC e ntlafatsa ho tenyetseha le ho hanyetsa ha mapheo a liphetolelo tse thehiloeng ho samente, e fana ka nako e telele sebakeng se felileng.
Consistency: E thusa ho boloka botsitso bo lakatsehang ba phepelo nakong ea kaho, ho thibela ho putlama le ho netefatsa botenya bo tšoanang.
3.4 Metsoako ea ho ikemela:
Phallo: Har'a metsoako ea ho ikemela, HPMC e ntlafatsa phallo, ho etsa hore ho hasana le ho betla ho be bonolo.
Ho boloka Metsi: E thibela tahlehelo e potlakileng ea mongobo, e netefatsa pheko e nepahetseng le nts'etsopele ea thepa e lakatsehang.
3.5 Lihlahisoa tsa Gypsum:
Ho lumellana: HPMC e sebelisoa lihlahisoa tse thehiloeng ho gypsum ho laola ho tsitsisa le ho beha nako.
Ho boloka metsi: E thibela ho omisoa pele ho nako ea motsoako oa plaster mme e khothalletsa ho phalla hantle.
4. Melemo ea ho sebelisa HPMC kahong:
Ts'ebetso e Ntlafetseng: HPMC e ntlafatsa ts'ebetso ea thepa ea mohaho, e etsa hore ho be bonolo ho sebetsana le ho e sebelisa.
Ho boloka metsi: Thepa ea ho boloka metsi ea HPMC e kenya letsoho pholisong e sebetsang ea lisebelisoa tsa samente.
Tlamahano le tlamahano: E ntlafatsa thepa ea tlamahano le tlamahano ea lihlahisoa tsa mohaho, kahoo e etsa hore mohaho o be matla le o tšoarellang haholoanyane.
Thickening: Joaloka motenya, HPMC e fana ka viscosity e hlokahalang ho mefuta e fapaneng ea thepa ea mohaho ho netefatsa ts'ebeliso e nepahetseng.
Khanyetso ea Crack: Ho eketsoa ha HPMC ho ntlafatsa ho feto-fetoha ha maemo le ho hanyetsa ho phatloha ha bokaholimo bo felileng.
Ho beha Taolo ea Nako: HPMC e fana ka taolo e betere ho feta nako ea ho beha thepa e thehiloeng ho samente.
5. Liphephetso le maikutlo:
Taolo ea Tekanyo: Tekanyo e nepahetseng e bohlokoa ho fihlela ts'ebetso e lakatsehang mme ts'ebeliso e feteletseng ea HPMC e ka baka litlamorao tse mpe.
Ho lumellana: Ho lumellana le lisebelisoa tse ling le lisebelisoa tsa mohaho ho lokela ho nahanoa ho thibela liphello tse mpe.
Tšusumetso ea Tikoloho: Le hoja HPMC ka boeona e nkoa e batla e bolokehile, phello ea tikoloho ea tlhahiso ea eona le ho lahla e lokela ho nkoa.
6. Qetello:
Ka bokhutšoanyane, hydroxypropyl methylcellulose (HPMC) e bapala karolo ea bohlokoa indastering ea kaho, e fana ka melemo e mengata e fapaneng ea likopo.Lintho tsa eona tse ikhethang tse kang ho boloka metsi, ho teteka le ho ntlafatsa ho khomarela ho etsa hore e be tlatsetso ea bohlokoa ha ho etsoa lirekere, li-adhesives, plasters le lisebelisoa tse ling tsa mohaho.Leha ho na le mathata a amanang le taolo ea litekanyetso le maemo a tikoloho, tšusumetso e ntle ea HPMC ts'ebetsong le ho tšoarella ha lihlahisoa tsa kaho e etsa hore e be karolo ea bohlokoa ea lisebelisoa tsa sejoale-joale tsa kaho.Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, HPMC e kanna ea lula e le karolo ea bohlokoa ho ntlafatseng boleng le katleho ea thepa ea kaho le lits'ebetso.
