Indasteri ea kaho ke lekala la bohlokoa le akaretsang mesebetsi e mengata ho tloha ho haheng matlo a bolulo ho isa ho haheng merero e meholo ea meralo ea motheo. Indastering ena, tšebeliso ea li-additives le thepa e fapaneng e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso le ts'ebetso ea thepa ea kaho. Hydroxypropyl methylcellulose (HPMC) ke sehlomathiso sa bohlokoa haholo. HPMC ke motsoako o sebetsang ka bongata o nang le lits'ebetso tse ngata lefapheng la kaho ka lebaka la thepa ea eona e ikhethang.
1. Litšobotsi tsa hydroxypropyl methylcellulose
Hydroxypropylmethylcellulose ke polymer e entsoeng ka semisynthetic e nkiloeng ho cellulose. E etsoa ka phetoho ea lik'hemik'hale ea cellulose, haholo-holo ka ho e phekola ka propylene oxide le methyl chloride. Ts'ebetso ena e hlahisa metsoako e nang le thepa e ikhethang e etsang hore e be e loketseng lits'ebetsong tse fapaneng tsa kaho.
Ho Boloka Metsi: E 'ngoe ea litšobotsi tsa bohlokoa tsa HPMC ke bokhoni ba eona ba ho boloka metsi. Thepa ena e bohlokoa haholo thepa ea kaho joalo ka li-mortar, moo ho boloka metsi ho thusang ho atolosa ho sebetsa ha motsoako, ho lumella kaho le ho qeta hantle.
Ho teteana: HPMC e sebetsa e le moemeli oa ho teteana mefuteng ea kaho. Ka ho eketsa ho teteana ha thepa, e ntlafatsa botsitso le botsitso ba eona, ka hona e ntlafatsa ts'ebetso ea eona nakong ea ts'ebeliso.
Ho khomarela: HPMC e ntlafatsa ho khomarela ha thepa ea kaho ho substrate, e khothalletsa ho khomarelana hamolemo le ho fokotsa kotsi ea ho qhelelana kapa ho qhelelana.
Ho Hlahisa Filimi: HPMC e oma ho etsa filimi e tšesaane, e tenyetsehang e fanang ka tšireletso holim'a metsi. Thepa ena e thusa haholo ho penteng le ho eketsa ho tšoarella le ho hanyetsa mabaka a tikoloho.
2. Tšebeliso ea hydroxypropyl methylcellulose kahong
Ho tenyetseha ha HPMC ho ipapisitse le mefuta e mengata ea lits'ebetso indastering ea kaho. Tse ling tsa lits'ebetso tsa bohlokoa li kenyelletsa:
Likhomaretsi tsa Lithaele le Li-Grout: HPMC e sebelisoa hangata ho likhomaretsi tsa lithaele le li-grout ho ntlafatsa bokhoni ba tsona ba ho sebetsa, ho khomarela le ho boloka metsi. E thusa ho thibela ho honyela le ho petsoha ha ka nako e ts'oanang e ntlafatsa kamano pakeng tsa lithaele le substrate.
Li-plaster le li-plaster tsa samente: Li-plaster le li-plaster tsa samente, HPMC ke sesebelisoa sa bohlokoa sa ho laola botsitso le ho ntlafatsa ho sebetsa hantle. E etsa hore tšebeliso e be bonolo ebile e fokotsa ho thekesela kapa ho putlama ha thepa.
Metswako e iketsang e lekana: Hangata HPMC e kenyelletsoa metswakong e iketsang e lekana ho lokisa litšobotsi tsa phallo ea tsona le ho thibela karohano ea kakaretso. Sena se hlahisa bokaholimo bo boreleli, bo bataletseng bo loketseng ho kenngoa ha fatše ka mor'a moo.
Mekhoa ea ho Thibela le ho Qetela ea Kantle (EIFS): EIFS e itšetlehile ka likhomaretsi le lipente tse thehiloeng ho HPMC ho khomarela liphanele tsa ho thibela ho ruruha ho substrate le ho fana ka qetello e sireletsang. HPMC e ntlafatsa ho tšoarella le ho hanyetsa boemo ba leholimo ba sistimi ea EIFS, e atolosa bophelo ba eona ba ts'ebeletso.
Lihlahisoa tsa Gypsum: HPMC e sebelisoa lihlahisoa tse thehiloeng ho gypsum tse kang motsoako oa manonyeletso le stucco ho ntlafatsa bokhoni ba ho sebetsa, ho khomarela le ho hanyetsa mapetso. E boetse e ntlafatsa qetello ea bokaholimo le ho khona ho santa ha thepa ea plaster.
3. Melemo ea ho sebelisa hydroxypropyl methylcellulose kahong
Tšebeliso ea HPMC e fa litsebi tsa kaho melemo e 'maloa, ho kenyeletsoa:
Ho ntlafala ha bokgoni ba ho sebetsa: HPMC e ntlafatsa bokgoni ba ho sebetsa ba thepa ya kaho, e etsa hore ho be bonolo ho e tshwara, ho e sebedisa le ho e qeta. Sena se eketsa tlhahiso mme se fokotsa ditjeo tsa basebetsi.
Tshebetso e Ntlafaditsweng: Thepa ya HPMC e thusa ho ntlafatsa dibopeho tsa tshebetso tse kang ho kgomarela, ho boloka metsi le ho tshwarella, e leng se fellang ka diphetho tsa boleng bo hodimo tsa kaho.
Ho tsamaellana: HPMC e tsamaellana le mefuta e meng ya thepa ya kaho le di-additives, e leng se dumellang diforomo tse feto-fetohang tse fihlelang ditlhoko tse ikgethang tsa projeke.
Botsitso ba Tikoloho: HPMC e nkiloe mehloding e nchafatsoang ya cellulose mme e ka bola, e leng se etsang hore e be kgetho e tsitsitseng ya tikoloho bakeng sa ditshebediso tsa kaho.
Ho Sebetsa ka Botlalo: Leha theko ea pele ea HPMC e ka ba holimo ha e bapisoa le li-additives tsa setso, ts'ebetso ea eona le melemo ea tlhahiso hangata li lokafatsa matsete a nako e telele.
Hydroxypropyl methylcellulose e bapala karolo ea bohlokoa indastering ea kaho, ka thepa ea eona e ikhethang le melemo e thusang ho ntlafatsa ts'ebetso, ho tšoarella le botsitso ba thepa ea kaho le litsamaiso. Ho tloha ho ntlafatseng bokhoni ba ho sebetsa le ho khomarela ho ea ho ntlafatseng ho boloka metsi le ho tšoarella, HPMC e fetohile tlatsetso ea bohlokoa thepa ea kaho. Litšebeliso tse fapaneng tsa kaho. Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, tlhoko ea HPMC e lebelletsoe ho hola, e susumetsoa ke tlhoko ea litharollo tse sebetsang hantle le tse tšoarellang. Ka hona, lipatlisiso tse ling le boqapi nts'etsopele le ts'ebeliso ea HPMC lia hlokahala ho fihlela litlhoko tse fetohang tsa indasteri ea kaho.
