HPMC le HEMC ke lipolima tse peli tsa bohlokoa tse 'nileng tsa sebelisoa haholo thepa ea kaho.Ba phetha karolo ea bohlokoa ho ntlafatsa tshebetso le boleng ba thepa ea mohaho.Sehloohong sena, re tla hlahisa thepa le ts'ebeliso ea HPMC le HEMC ka thepa ea kaho.
HPMC, eo hape e tsejoang e le hydroxypropyl methylcellulose, ke cellulose ether e nkiloeng ho makhasi a lehong le likhoele tsa k'hothone.Ke phofo e sa nkheng, e sa latsoeheng, e seng chefo e qhibilihang metsing.HPMC e na le thepa e ntle ea ho boloka metsi, e teteaneng le e emulsifying, e etsang hore e be tlatsetso e tsebahalang ea thepa ea moaho.
E 'ngoe ea likopo tse atileng haholo bakeng sa HPMC ke likhomaretsi tsa lithaele tse thehiloeng ho samente.HPMC e ka ntlafatsa matla a bond le ho sebetsa ha sekhomaretsi, hape e ka thibela lithaele hore li se ke tsa thella kapa tsa oela nakong ea ho kenya.Ho feta moo, HPMC e ka fokotsa ho monya ha metsi ha lithaele, ho bohlokoa bakeng sa ho tšoarella le ho phela nako e telele ha ho kengoa lithaele.
HPMC e boetse e sebelisoa haholo ho metsoako ea cementitious self-leveling.Metsoako ea ho ikemela e sebelisoa ho lekanya mekato e sa lekaneng ea konkreite, 'me HPMC e ka ntlafatsa phallo ea komporo le thepa ea ho lekanya.HPMC e boetse e thibela motsoako oa ho ikemela ho tloha ho etsa mapetsong le ho fokotseha, e leng ntho ea bohlokoa bakeng sa botšepehi ba tsamaiso ea fatše.
Tšebeliso e 'ngoe ea HPMC ke li-renders le li-plaster tse thehiloeng ho samente.HPMC e ka ntlafatsa ho khomarela le ho sebetsa ha plaster kapa stucco, hape e ka ntlafatsa ts'ebetso e sa keneleng metsi.Sena ke sa bohlokoa ho sireletsa enfelopo ea mohaho le ho thibela tšenyo ea mongobo.
HEMC, eo hape e tsejoang e le hydroxyethyl methylcellulose, ke ether e 'ngoe ea cellulose e sebelisoang haholo ho thepa ea mohaho.HEMC e tšoana le HPMC mabapi le ts'ebetso le lits'ebetso, empa e na le melemo e ikhethang e etsang hore e tšoanelehe bakeng sa lits'ebetso tse itseng.
E 'ngoe ea melemo e ka sehloohong ea HEMC ke viscosity ea eona e phahameng.Sena se etsa hore e be se loketseng bakeng sa ho sebelisoa lijase tse teteaneng le lipente ho ntlafatsa phallo le boemo.HEMC e boetse e sebelisoa haholo ka li-caulks le sealants, tse ka ntlafatsang ho thibela metsi le ho khomarela lihlahisoa.
HEMC e boetse e sebelisoa hangata ho thepa ea moaho e thehiloeng ho gypsum joalo ka metsoako e kopaneng le stucco.HEMC e ntlafatsa ho sebetsa le ho khomarela metsoako e kopanetsoeng hape e thibela ho fokotseha le ho phunyeha.Ho phaella moo, HEMC e ka ntlafatsa ho hanyetsa metsi le ho hanyetsa hlobo ea li-plaster, tse bohlokoa bakeng sa boleng ba moea oa ka hare oa mehaho.
Qetellong, HPMC le HEMC ke lipolima tse peli tsa bohlokoa tse nang le lisebelisoa tse ngata tsa thepa ea kaho.Ba phetha karolo ea bohlokoa ho ntlafatsa tshebetso le boleng ba thepa ea mohaho le ho thusa ho theha mehaho e tšoarellang, e sebetsang hantle le e tsitsitseng.Ha lisebelisoa tsena li ntse li tsoela pele ho ntlafatsoa le ho hloekisoa, re ka lebella litharollo tse ncha le tse tsoetseng pele tsa moaho nakong e tlang.
