Indasteri ea kaho ke lekala la bohlokoa le amang mesebetsi e mengata e fapaneng ho tloha ho aha matlo a bolulo ho isa ho ho aha merero e meholo ea meralo ea motheo. Indastering ena, tšebeliso ea li-additives le lisebelisoa tse fapaneng e phetha karolo ea bohlokoa ho ntlafatsa ts'ebetso le ts'ebetso ea thepa ea mohaho. Hydroxypropyl methylcellulose (HPMC) ke tlatsetso ea bohlokoa haholo. HPMC ke komporo e sebetsang ka bongata e nang le lits'ebetso tse ngata lekaleng la kaho ka lebaka la thepa ea eona e ikhethang.
1. Litšobotsi tsa hydroxypropyl methylcellulose
Hydroxypropylmethylcellulose ke semi-synthetic polymer e nkiloeng ho selulose. E entsoe ka phetoho ea lik'hemik'hale ea selulose, haholo-holo ka ho e phekola ka propylene oxide le methyl chloride. Mokhoa ona o hlahisa metsoako e nang le thepa e ikhethang e etsang hore e be e loketseng bakeng sa mefuta e fapaneng ea likopo tsa kaho.
Poloko ea Metsi: E 'ngoe ea thepa ea bohlokoa ea HPMC ke bokhoni ba eona ba ho boloka metsi. Thepa ena ke ea bohlokoa ka thepa ea kaho e kang seretse, moo ho boloka metsi ho thusang ho atolosa ho sebetsa ha motsoako, ho lumella ho haha ho betere le ho qeta.
Thickening: HPMC e sebetsa joalo ka motenya meahong ea meaho. Ka ho eketsa viscosity ea thepa, e ntlafatsa ho tsitsisa le botsitso ba eona, kahoo e ntlafatsa ts'ebetso ea eona nakong ea kopo.
Ho khomarela: HPMC e ntlafatsa ho khomarela lisebelisoa tsa mohaho ho substrate, ho khothalletsa maqhama a betere le ho fokotsa kotsi ea delamination kapa delamination.
Tlhahiso ea Lifilimi: HPMC e omella ho etsa filimi e tšesaane, e tenyetsehang e fanang ka thibelo e sireletsang holim'a metsi. Thepa ena e na le thuso ka ho khetheha lijaneng le lipenteng ho matlafatsa botsitso le ho hanyetsa maemo a tikoloho.
2. Kopo ea hydroxypropyl methylcellulose kahong
Ho feto-fetoha ha maemo ha HPMC ho fana ka lits'ebetso tse fapaneng indastering ea kaho. Lisebelisoa tse ling tsa bohlokoa li kenyelletsa:
Likhomaretsi tsa Lithaele le Li-Grouts: HPMC e atisa ho sebelisoa ho li-adhesives le li-grouts ho ntlafatsa ts'ebetso ea tsona, ho khomarela le ho boloka metsi. E thusa ho thibela ho fokotseha le ho phunyeha ha ho ntse ho matlafatsa maqhama pakeng tsa tile le substrate.
Lipolasetere tsa samente le lipolasetere: Lisamenteng le lipolasetereng tsa samente, HPMC ke tlatsetso ea bohlokoa ho laola botsitso le ho ntlafatsa ts'ebetso. E etsa hore ts'ebeliso e be bonolo ebile e fokotsa ho theoha kapa ho thella ha thepa.
Metsoako ea ho ikemela: HPMC hangata e kenyeletsoa ka har'a metsoako ea ho ikemela ho lokisa thepa ea bona ea phallo le ho thibela karohano e kopaneng. Sena se hlahisa sebaka se boreleli, se boemong bo loketseng bakeng sa ho kenngoa ha fatše ho latelang.
Exterior Insulation and Finishing Systems (EIFS): EIFS e itšetlehile ka li-adhesives tse thehiloeng ho HPMC le liphahlo ho khomarela liphanele tsa ho pata ho substrate le ho fana ka tšireletso ea tšireletso. HPMC e ntlafatsa ho tšoarella le ho hanyetsa boemo ba leholimo ba sistimi ea EIFS, e lelefatsa bophelo ba eona ba ts'ebeletso.
Lihlahisoa tsa Gypsum: HPMC e sebelisoa lihlahisoa tse thehiloeng ho gypsum tse kang motsoako o kopantsoeng le stucco ho ntlafatsa ts'ebetso, ho khomarela le ho hanyetsa crack. E boetse e ntlafatsa sephetho sa bokaholimo le sandability ea lisebelisoa tsa plaster.
3. Melemo ea ho sebelisa hydroxypropyl methylcellulose kahong
Ts'ebeliso ea HPMC e fa litsebi tsa kaho melemo e mengata, ho kenyelletsa:
Ts'ebetso e ntlafetseng: HPMC e ntlafatsa ts'ebetso ea thepa ea mohaho, e etsa hore ho be bonolo ho sebetsana le eona, ho e sebelisa le ho e qeta. Sena se eketsa tlhahiso le ho fokotsa litšenyehelo tsa basebetsi.
Ts'ebetso e Ntlafetseng: Thepa ea HPMC e thusa ho ntlafatsa litšobotsi tsa ts'ebetso tse kang ho khomarela, ho boloka metsi le ho tšoarella, ho fella ka liphello tsa boleng bo phahameng ba kaho.
Tšebelisano: HPMC e sebelisana le lisebelisoa tse ling tse fapaneng tsa kaho le litlatsetso, e lumellang hore ho be le libopeho tse fapaneng tse fihlelang litlhoko tse ikhethileng tsa projeke.
Tšireletseho ea Tikoloho: HPMC e tsoa mehloling ea selulose e nchafalitsoeng 'me e khona ho senyeha, ho e etsa khetho e tsitsitseng ea tikoloho bakeng sa lits'ebetso tsa kaho.
Katleho ea Litšenyehelo: Le hoja litšenyehelo tsa pele tsa HPMC li ka ba holimo ha li bapisoa le li-additives tsa setso, melemo ea eona ea ts'ebetso le tlhahiso hangata e lokafatsa matsete a nako e telele.
Hydroxypropyl methylcellulose e phetha karolo ea bohlokoa indastering ea kaho, ka thepa ea eona e ikhethang le melemo e thusang ho ntlafatsa ts'ebetso, ho tšoarella le ho tšoarella ha thepa ea mohaho le litsamaiso. Ho tloha ho ntlafatsa ts'ebetso le ho khomarela ho matlafatsa ho boloka metsi le ho tšoarella, HPMC e fetohile tlatsetso ea bohlokoa ho thepa ea mohaho. Lisebelisoa tse fapaneng tsa kaho. Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, tlhokahalo ea HPMC e lebelletsoe ho hola, e tsamaisoa ke tlhoko ea litharollo tse sebetsang hantle, tse tšoarellang. Ka hona, liphuputso tse ling le boqapi ho nts'etsopele le ts'ebeliso ea HPMC lia hlokahala ho fihlela litlhoko tse fetohang tsa indasteri ea kaho.
