Hydroxypropyl methylcellulose (HPMC) ke polymer e sebetsang ka bongata e sebelisoang haholo indastering ea kaho ka lebaka la thepa le ts'ebetso ea eona e ikhethang.Motsoako o tsoa ho cellulose mme o fetotsoe ka ho eketsa lihlopha tsa hydroxypropyl le methyl.Ka hona HPMC e bonts'a mefuta e mengata ea thepa e e etsang hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng lekaleng la kaho.
Melemo ea ho boloka metsi le ho tenya:
E 'ngoe ea mesebetsi ea mantlha ea HPMC kahong ke bokhoni ba eona ba ho sebetsa joalo ka setsi sa ho boloka metsi.Sena se bohlokoa bakeng sa lisebelisoa tse thehiloeng ho samente, kaha ho boloka tekanyo e nepahetseng ea metsi ho bohlokoa bakeng sa hydration e nepahetseng le pheko.HPMC e thusa ho thibela mouoane o potlakileng oa metsi, ho netefatsa hore motsoako oa samente o lula o sebetsa ka nako e telele.
HPMC e ka boela ea sebelisoa e le motenya ho eketsa viscosity ea thepa ea mohaho.Sena ke sa bohlokoa ka ho khetheha lits'ebetsong tse kang li-adhesives tsa lithaele le metsoako e kopanetsoeng, e hlokang ho tsitsisa ho hoholo bakeng sa kopo e ntle le ho tlamahanngoa.
Matla a ntlafetseng:
HPMC thusa ho ntlafatsa workability ea seretse le metsoako konkreite.Ka ho laola litaba tsa metsi le ho ntlafatsa thepa ea rheological, lisebelisoa tsena li ka sebetsanoa le ho sebelisoa habonolo.Sena se bohlokoa ka ho khetheha nakong ea ts'ebetso ea kaho joalo ka ho lipola, ho fana le mosebetsi oa masonry.
Ntlafatsa ho khomarela ha sekhomaretsi sa lithaele:
Likhomaretsing tsa lithaele, HPMC e ntlafatsa ho khomarela ka ho fana ka viscosity e tsitsitseng.Sena se tiisa hore lithaele li khomarela ka thata ho substrate, ho thibela mathata a kang ho senya kapa ho senya ka nako.Thepa e laoloang ea ho boloka metsi ea HPMC le eona e bapala karolo ea bohlokoa ho fihlelleng ho khomarela hantle.
Crack resistance le ho ntlafala ha nako e telele:
Ho eketsa HPMC ho metsoako e thehiloeng ho samente ho ka thusa ho fokotsa mapetsong a ho honyela.Sena se na le molemo ka ho khetheha bakeng sa likopo tse kang konkreite, moo ho fokotsa mapetsong ho leng bohlokoa bakeng sa botšepehi ba sebopeho le ho tšoarella ha sehlahisoa se felileng.HPMC e thusa ho boloka botšepehi ba thepa ha e ntse e phekola le lilemo.
Metsoako ea ho ikemela:
HPMC e atisa ho sebelisoa ka lik'hemik'hale tsa ho ikemela ho etsa sebaka se boreleli, se bataletseng ho lisebelisoa tsa fatše.Thepa ea ho boloka metsi ea HPMC e phetha karolo ea bohlokoa ho laola nako ea ho omisa ea metsoako ena, e lumellang ho ikemela hantle ntle le ho ipeha pele ho nako.
Lihlahisoa tse thehiloeng ho Gypsum:
HPMC ke tlatsetso ea bohlokoa lihlahisoa tsa gypsum tse kang gypsum.E ntlafatsa ts'ebetso ea stucco, e ntlafatsa ho khomarela holimo, 'me e thusa ho finyella ho tsitsa le ho qetela.Bokhoni ba ho ts'oara metsi ba HPMC bo molemo haholo lits'ebetsong tse thehiloeng ho gypsum.
Litsamaiso tsa Kantle tsa Insulation le Finishing (EIFS):
EIFS ke mokhoa o tummeng oa ho roala ka har'a meaho, o fana ka mohatsela oa mocheso le qetello ea mokhabiso.HPMC e sebelisoa mefuteng ea EIFS ho ntlafatsa thepa ea sekhomaretsi ea primer le ho netefatsa maqhama a matla pakeng tsa boto ea ho kenya letsoho le substrate.
Seretse sa insulation:
HPMC ke karolo ea bohlokoa ea seretse se kenyang mocheso.Likarolo tsena li sebelisoa ha ho hahoa meaho e baballang matla ho matlafatsa thepa ea ho thibela mocheso.HPMC e thusa ho boloka botsitso bo hlokahalang e le hore lirekere tsena li ka sebelisoa ka nepo libakeng tse fapaneng.
Ho lokolloa ha li-additives tse laoloang:
HPMC e ka sebelisoa ho kenyelletsa le ho laola ho lokolloa ha li-additives tse fapaneng ho thepa ea mohaho.Sena se bohlokoa haholo ha ho lokolloa butle-butle ha lintho tse kang biocides kapa corrosion inhibitors ho hlokahala ho finyella ts'ebetso ea nako e telele le tšireletso ea thepa ea mohaho.
Emulsion botsitso:
Lits'ebetsong tsa kaho tse sebelisang li-emulsion, tse kang li-emulsion tsa asphalt, HPMC e sebetsa e le stabilizer.E thusa ho thibela metsi le sekontiri ho arohana, ho netefatsa botsitso le ho tšoana ha emulsion.
Ho lumellana le li-additives tse ling:
HPMC e lumellana le mefuta e meng ea li-additives tsa kaho.Ts'ebetso ena e fapaneng e lumella baetsi ba lihlahisoa hore ba lokise ts'ebetso ea thepa ea mohaho ho latela litlhoko tse khethehileng tsa morero, ebang ke ho fetola nako ea ho beha, ho ntlafatsa ho khomarela kapa ho ntlafatsa tshebetso ea kakaretso ea thepa.
Mekhoa ea kaho e tala:
HPMC hangata e ratoa mekhoeng ea kaho e tala ka lebaka la ho senyeha ha eona le tšusumetso e tlase ea tikoloho.Tšebeliso ea eona e lumellana le melao-motheo ea kaho e tsitsitseng, e etsang hore e be khetho e khahlehang bakeng sa merero e bolokang tikoloho.
Motsoako o Kopanetsoeng le Coating ea Sebopeho:
Likhomaretsing tse kopantsoeng le liphahlo tsa masela, HPMC e ntlafatsa ts'ebetso ka kakaretso ka ho fana ka rheology e hlokahalang, lisebelisoa tse bonolo le thepa ea sanding.E boetse e phetha karolo ea ho ntlafatsa ho khomarela lisebelisoa tsena ho ea holimo.
Li-caulks le li-sealants:
Ha ho etsoa li-caulks le li-sealants, HPMC e thusa ho finyella tumellano e lakatsehang le extrudability.E thusa ho ntlafatsa ts'ebetso ea kakaretso ea lihlahisoa tsena ka ho netefatsa hore ho khomarela hantle le ho feto-fetoha ha maemo ho bolokiloe ka nako.
Fokotsa ho fokotseha ha lits'ebetso tse otlolohileng:
Bakeng sa lits'ebetso tse otlolohileng joalo ka lipente le lipente, HPMC e thusa ho thibela ho senyeha ka ho fana ka thepa ea thixotropic.Sena se bohlokoa bakeng sa ho boloka botenya bo ts'oanang holim'a libaka tse otlolohileng ntle le ho putlama kapa ho phalla ha thepa.
Qetellong, hydroxypropyl methylcellulose e phetha karolo ea bohlokoa indastering ea kaho, e fana ka melemo e mengata e fapaneng mabapi le ho boloka metsi, ho sebetsa, ho khomarela le ho tšoarella.Tšebeliso ea eona e feto-fetohang mefuteng e fapaneng ea thepa ea mohaho e etsa hore e be tlatsetso ea bohlokoa ho finyella thepa e lakatsehang ea sehlahisoa sa ho qetela.Ha mekhoa ea kaho e ntse e tsoela pele ho fetoha, HPMC e kanna ea ba ea bohlokoa haholo ho ntlafatsa ts'ebetso le botsitso ba thepa ea moaho.
