HEMC FOR Dry Mixed Mortars

Ka har'a seretse sa motsoako o omileng, Hydroxyethyl Methylcellulose (HEMC) e sebetsa e le tlatsetso ea bohlokoa e fanang ka lisebelisoa tse fapaneng tse sebetsang tse ntlafatsang ts'ebetso ea motsoako oa seretse. Metsoako e omileng ke metsoako e entsoeng pele e tsoakiloeng e sebelisoang ha ho etsoa lits'ebetso tse joalo ka likhomaretsi tsa lithaele, li-renderings, plasters le grouts. Mona ke kamoo HEMC e leng molemo kateng bakeng sa seretse sa motsoako o omileng:

1. Ho Boloka Metsi: HEMC e na le thepa e babatsehang ea ho boloka metsi, e leng ea bohlokoa ka har'a seretse sa motsoako o omileng. E thusa ho boloka metsi ka har'a motsoako oa seretse, ho thibela ho omisoa pele ho nako le ho netefatsa hore ho na le metsi a lekaneng a lisebelisoa tsa samente. Thepa ena e ntlafatsa ts'ebetso, e lelefatsa nako e bulehileng, 'me e ntlafatsa ho khomarela li-substrates.
2. Thickening le Rheology Control: HEMC e sebetsa e le motenya le rheology modifier, e susumetsang ho tsitsisa le ho phalla ha motsoako oa seretse. Ka ho lokisa li-viscosity le thepa ea rheological, HEMC e thusa litšoaneleho tse ntle tsa ts'ebeliso, tse kang ho ata ho ntlafetseng, ho fokotsa ho fokotseha, le ho matlafatsa momahano.
3. Ntlafatso ea Ts'ebetso e Ntlafetseng: Ho ba teng ha HEMC ho matlafatsa ts'ebetso ea lirekere tse omeletseng, ho etsa hore ho be bonolo ho li kopanya, ho li sebelisa le ho li tšoara. E khothalletsa trowelability e betere, e lumellang ts'ebeliso e bonolo le e ts'oanang holim'a bokaholimo. Sena se fella ka ho ntlafala ha holimo le botle ba kakaretso.
4. Fokotsa Shrinkage le Cracking: HEMC e thusa ho fokotsa ho fokotseha le ho phunyeha ka har'a seretse se omileng sa motsoako ka ho ntlafatsa homogeneity ea motsoako le ho fokotsa sekhahla sa ho fetoha mouoane oa metsi. Sena se tlatsetsa ho tšoarella ha nako e telele le botšepehi ba sebopeho sa seretse se sebelisitsoeng.
5. Ntlafatso ea Khomarelo: HEMC e ntlafatsa ho khomarela seretse se omeletseng ho li-substrates tse fapaneng, ho kenyeletsoa konkreite, masonry le lithaele tsa ceramic. E theha maqhama a matla pakeng tsa seretse le substrate, e leng se hlahisang thepa e ntle ea ho khomarela le ho eketsa matla a tlamahano.
6. Ho lumellana le Li-additives tse ling: HEMC e lumellana le mefuta e mengata ea lisebelisoa tse ling tse atisang ho sebelisoa mefuteng e omileng ea seretse se omileng, tse kang li-air-entraining agents, li-plasticizers, le li-accelerator tsa ho beha. Sena se lumella ho feto-fetoha ha sebopeho le ho itlhophisa ho fihlela litlhoko tse khethehileng tsa ts'ebetso.

HEMC e bapala karolo ea bohlokoa ho ntlafatsa ts'ebetso ea lirekere tse omeletseng ka ho ntlafatsa ts'ebetso, ho khomarela, ho boloka metsi, le boleng ka kakaretso. Tšebeliso ea eona e thusa ho etsa bonnete ba ho kenngoa ka katleho le ka katleho ha lisebelisoa tse fapaneng tsa kaho ha ho ntse ho boloka botsitso le ho tšoarella lits'ebetsong tse felileng.
