Melemo ea ho sebelisa MHEC ho hlahisa putty le gypsum powder
MHEC e tsoa ho selulose mme e hlahisoa ka mokhoa oa ho fetola lik'hemik'hale.Ke motsoako o qhibilihang ka metsi o sebelisoang haholo e le motenya, stabilizer le emulsifier indastering ea kaho.Ha e kenngoa ho li-putty le gypsum powders, MHEC e koahela likaroloana, e fana ka lera le sireletsang le ba thibelang hore ba se ke ba kopana le ho lula.Sena se hlahisa motsoako o lekaneng, o tsitsitseng o bonolo ho sebetsa le ho fana ka qetello e molemo.
E 'ngoe ea melemo ea mantlha ea ho sebelisa MHEC ka li-putty le li-plaster ke hore e ntlafatsa thepa ea bona ea ho boloka metsi.MHEC e monya le ho boloka mongobo, e etsa bonnete ba hore motsoako o lula o sebelisoa ebile ha o ome kapele haholo.Sena ke sa bohlokoa ka ho khetheha libakeng tse chesang le tse omileng moo motsoako o fetohang ka potlako o sa sebelisoeng, o fellang ka qetello e senyehileng.
MHEC e boetse e ntlafatsa ho sebetsa le nako ea ho sebetsa ea li-putty le plasters.MHEC e nolofatsa ho kopanya le ho sebelisa motsoako ka ho boloka mongobo le ho thibela motsoako ho omella.Ho phaella moo, boreleli bo boreleli ba MHEC bo lumella putty le stucco hore li hasane ka mokhoa o ts'oanang holim'a metsi ntle le ho siea makukuno kapa li-clumps, ho netefatsa qetello e se nang sekoli, e ntle.
Ntle le ho ntlafatsa sebopeho le ho sebetsa ha li-putty le li-plaster, MHEC e ka boela ea ntlafatsa thepa ea bona ea ho kopanya.Ka ho etsa lera le sireletsang ho pota-potile likaroloana, MHEC e tiisa hore ba tlamahane hantle ho feta holim'a metsi ao ba a phekolang.Sena se fella ka sebaka se matla, se tšoarellang haholoanyane seo ho seng bonolo hore se petsohe, se petsohe kapa se ebole ha nako e ntse e ea.

Ho ntlafatsa Putty le Gypsum Performance Ho Sebelisa MHEC
Ho ntlafatsa ts'ebetso ea putty le plaster powder, ke habohlokoa ho netefatsa hore MHEC e sebelisoa ka tekanyo e nepahetseng.Sena se bolela hore ho sebelisa palo e nepahetseng ea MHEC ho ka finyella ts'ebetso e lakatsehang le litšobotsi tsa putty kapa stucco e hlahisoang.
Lintlha tsa tikoloho tse ka amang ts'ebetso ea putty le gypsum powder li tlameha ho nkoa.Ka mohlala, libakeng tse chesang le tse omileng, ho ka 'na ha hlokahala hore ho eketsoe MHEC e eketsehileng ho netefatsa hore motsoako o lula o sebetsa le o tsitsitseng.
Ho bohlokoa ho netefatsa hore putty kapa stucco e sebelisoa ka nepo ho eketsa ts'ebetso ea eona.Sena se bolela ho latela litaelo tsa moetsi ka hloko le ho etsa bonnete ba hore motsoako o tsoakane hantle pele o sebelisoa.Ho phaella moo, lisebelisoa tse khethehileng li ka 'na tsa hlokoa ho etsa bonnete ba hore putty kapa stucco e sebelisoa ka tsela e ts'oanang le e tsitsitseng holim'a metsi a phekoloang.
MHEC ke tlatsetso ea bohlokoa e sebelisoang tlhahisong ea putty le plaster powder.E ntlafatsa thepa le thepa ea lisebelisoa tsena, ho ntlafatsa ts'ebetso ea tsona, ho boloka metsi, ho khomarela le ho hanyetsa moea le mongobo.Sena se fella ka qetello e tsitsitseng haholoanyane, e tšoarellang le e khahlehang eo ho seng monyetla o fokolang oa ho petsoha, ho phunya kapa ho ebola ha nako e ntse e ea.E le ho ntlafatsa ts'ebetso ea putty le gypsum powder, ke habohlokoa ho etsa bonnete ba hore tekanyo e nepahetseng ea MHEC e sebelisoa, ho nahanela maemo a tikoloho a ka amang ts'ebetso ea bona.Ho feta moo, ho bohlokoa ho sebelisa putty kapa stucco ka nepo ho eketsa ts'ebetso ea eona le ho fihlela sephetho se lakatsehang.
HEMC e sebelisoa ha ho etsoa samente ho ntlafatsa thepa ea eona Hydroxyethyl methylcellulose (HEMC) ke lik'hemik'hale tse sebelisoang haholo indastering ea kaho.Ke kamano pakeng tsa ho sebetsa, ho boloka metsi, thixotropy, joalo-joalo Matsatsing ana, mofuta o mocha oa cellulose ether o ntse o fumana tlhokomelo e eketsehileng.Se seng se hohetse tlhokomelo e eketsehileng ke hydroxyethyl methylcellulose (MHEC).
E 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa tse khethollang boleng ba lihlahisoa tsa samente ke ho sebetsa ha motsoako.Ke kamoo samente e leng bonolo ho kopanya, sebopeho le sebaka.Ho finyella sena, motsoako oa samente o lokela ho ba mokelikeli o lekaneng ho tšela le ho phalla habonolo, empa hape o lokela ho ba viscous ho lekana ho tšoara sebōpeho sa oona.MHEC e ka finyella thepa ena ka ho eketsa viscosity ea samente, kahoo e ntlafatsa ho sebetsa ha eona.
MHEC e ka boela ea potlakisa hydration ea samente le ho ntlafatsa matla a eona.Matla a ho qetela a samente a itšetlehile ka bongata ba metsi a sebelisoang ho e kopanya.Metsi a mangata haholo a tla fokotsa matla a samente, athe metsi a manyenyane haholo a tla etsa hore ho be thata haholo ho sebetsa ka oona.MHEC e thusa ho boloka palo e itseng ea metsi, kahoo ho netefatsa hore metsi a lekaneng a samente le ho khothalletsa ho thehoa ha maqhama a matla pakeng tsa likaroloana tsa samente.
MHEC e thusa ho fokotsa palo ea mapetsong a samente.Ha samente e ntse e phekola, motsoako oa fokotseha, o ka lebisang ho thehoeng ha mapheo haeba ho fokotseha ho sa laoloe.MHEC e thibela ho fokotseha hona ka ho boloka palo e nepahetseng ea metsi ka har'a motsoako, kahoo ho thibela samente ho senya.
MHEC e boetse e sebetsa e le filimi e sireletsang holim'a samente, e thibelang metsi ho tsoa holim'a metsi.Filimi ena e boetse e thusa ho boloka mongobo oa pele oa samente, ho fokotsa monyetla oa ho senya.
MHEC e boetse e loketse tikoloho.Ntlha ea pele, e ka senyeha, ho bolelang hore ha e lule tikolohong nako e telele.Ea bobeli, e ka thusa ho fokotsa bongata ba samente e hlokahalang mererong ea kaho.Sena ke hobane MHEC e eketsa ts'ebetso le viscosity ea samente, ho fokotsa tlhokahalo ea metsi a eketsehileng a fokotsang motsoako oa samente feela.
Tšebeliso ea MHEC ka samente e fana ka melemo e mengata 'me e ka kenya letsoho haholo indastering ea kaho.E ntlafatsa ho sebetsa ha motsoako oa samente, ho fokotsa palo ea mapetsong a entsoeng nakong ea ho folisa, ho khothalletsa metsi a samente le matla, 'me e sebetsa e le filimi e sireletsang holim'a samente.Ho feta moo, MHEC e molemong oa tikoloho.Ka hona, MHEC ke sehlahisoa sa bohlokoa bakeng sa indasteri ea kaho kaha e ntlafatsa boleng ba samente le ho fana ka melemo ho basebetsi le tikoloho.
