HEMC e sebelisoang ho Kaho

Hydroxyethyl Methyl Cellulose (HEMC) ke cellulose ether e sebelisoang haholo indastering ea kaho e le tlatsetso ea lisebelisoa tse fapaneng tsa moaho. HEMC e fana ka thepa e khethehileng ho lihlahisoa tsa kaho, ho ntlafatsa ts'ebetso ea tsona le ho tsamaisa mekhoa ea kaho. Mona ke kakaretso ea likopo, mesebetsi, le maikutlo a HEMC kahong:

1. Kenyelletso ea Hydroxyethyl Methyl Cellulose (HEMC) ka Kaho

1.1 Tlhaloso le Mohloli

Hydroxyethyl Methyl Cellulose (HEMC) ke derivative ea cellulose e fumanoang ka ho arabela methyl chloride ka alkali cellulose 'me ka mor'a moo e ethylating sehlahisoa ka ethylene oxide. Hangata e sebelisoa e le setei, se bolokang metsi, le stabilizer lits'ebetsong tsa kaho.

1.2 Seabo ho Lisebelisoa tsa Kaho

HEMC e tsejoa ka ho boloka metsi le ho teteka ha metsi, ho etsa hore e tšoanelehe bakeng sa mefuta e mengata ea thepa ea kaho moo rheology e laoloang le ho ntlafatsa ho sebetsa ho hlokahalang.

2. Mesebetsi ea Hydroxyethyl Methyl Cellulose ka Kaho

2.1 Poloko ea Metsi

HEMC e sebetsa e le moemeli ea sebetsang oa ho boloka metsi ka thepa ea kaho. E thusa ho thibela tahlehelo ea metsi ka potlako, ho netefatsa hore metsoako e lula e sebetsa nako e telele. Sena se bohlokoa haholo lihlahisoa tse thehiloeng ho samente moo ho boloka metsi a lekaneng ho leng bohlokoa bakeng sa ho tsamaisa metsi hantle.

2.2 Phetoho ea Thickening le Rheology

HEMC e sebetsa e le moemeli o teteaneng mekhoeng ea kaho, e susumetsang viscosity le thepa ea phallo ea thepa. Sena se molemo lits'ebetsong tse joalo ka likhomaretsi tsa lithaele, li-grouts le lirekere, moo rheology e laoloang e ntlafatsang ts'ebetso ea ts'ebeliso.

2.3 Sebetsa se Ntlafetseng

Ho kenyelletsoa ha HEMC ho thepa ea kaho ho ntlafatsa ts'ebetso, ho etsa hore ho be bonolo ho kopanya, ho jala, le ho sebelisa. Sena se bohlokoa lits'ebetsong tse fapaneng, tse kenyelletsang ho lipola, ho fana, le ho sebetsa ka konkreite.

2.4 Ho tsitsisa

HEMC e thusa ho tsitsisa ha metsoako, ho thibela karohano le ho netefatsa ho ajoa ka mokhoa o ts'oanang oa likarolo. Ho tsitsisa hona ho bohlokoa mekhoeng eo ho eona ho boloka botsitso ho bohlokoa, joalo ka metsoako ea ho ikemela.

3. Likopo ho Kaho

3.1 Likhomaretsi tsa Lithaele le Li-Grouts

Ka li-adhesives le li-grouts, HEMC e ntlafatsa ho boloka metsi, e ntlafatsa ho khomarela, 'me e fana ka viscosity e hlokahalang bakeng sa kopo e bonolo. E kenya letsoho mosebetsing oa kakaretso oa lihlahisoa tsena.

3.2 Li-Mortars le Renders

HEMC e atisa ho sebelisoa ka seretse 'me e fana ka metsoako ho ntlafatsa ts'ebetso, ho thibela ho senyeha, le ho matlafatsa ho khomarela motsoako ho substrates.

3.3 Metsoako ea ho Ikemela

Ka lik'hemik'hale tsa ho ikemela, HEMC e thusa ho boloka thepa ea phallo e lakatsehang, ho thibela ho rarolla, le ho etsa bonnete ba hore sebaka se boreleli le se lekaneng.

3.4 Lihlahisoa tse Thehiloeng ka Samente

HEMC e eketsoa ho lihlahisoa tse thehiloeng ho samente joalo ka li-grouts, li-admixtures tsa konkreite, le li-plaster ho laola viscosity, ho ntlafatsa ts'ebetso, le ho ntlafatsa ts'ebetso ka kakaretso.

4. Mehato le Litlhokomelo

4.1 Tekanyetso le Kamano

Tekanyetso ea HEMC ha ho etsoa kaho e lokela ho laoloa ka hloko ho finyella thepa e lakatsehang ntle le ho ama litšobotsi tse ling hampe. Ho lumellana le li-additives le lisebelisoa tse ling ho bohlokoa hape.

4.2 Tšusumetso ea Tikoloho

Ha ho khethoa li-additives tsa kaho, ho kenyelletsa le HEMC, ho lokela ho nahanoa ka phello ea bona ea tikoloho. Likhetho tse tšoarellang le tse bonolo tsa tikoloho li ntse li le bohlokoa haholo indastering ea kaho.

4.3 Litlhaloso tsa Sehlahisoa

Lihlahisoa tsa HEMC li ka fapana ho ea ka litlhaloso, 'me ho bohlokoa ho khetha kereiti e nepahetseng ho latela litlhoko tse ikhethang tsa kopo ea kaho.

5. Qetello

Hydroxyethyl Methyl Cellulose ke tlatsetso ea bohlokoa indastering ea kaho, e kenya letsoho ho bolokoeng ha metsi, ho tiisa le ho tsitsisa ha thepa e fapaneng ea moaho. Mehaho ea eona e fapaneng e etsa hore e tšoanelehe bakeng sa mefuta e mengata ea likopo, e ntlafatsa ts'ebetso le ts'ebetso ea mekhoa ea ho haha. Ho ela hloko litekanyetso, ho lumellana, le maemo a tikoloho ho netefatsa hore HEMC e eketsa melemo ea eona lits'ebetsong tse fapaneng tsa kaho.
