Hydroxyethyl Methyl Cellulose (HEMC)

Hydroxyethyl methyl cellulose (HEMC) ke polima e qhibilihang ka metsing e nkiloeng ho selulose. Ke motsoako o seng oa ionic, o se nang chefo, le o sa cheng o sebelisoang haholo lits'ebetsong tse fapaneng tsa indasteri le tsa bareki. HEMC e nkoa e le ea bohlokoa ka lebaka la bokhoni ba eona ba ho sebetsa e le sefetoleli se teteaneng, se kopanyang, le rheology lihlahisoa tse ngata.

HEMC e entsoe ka ho fetola lik'hemik'hale tsa tlhaho tsa cellulose likhoele. Ts'ebetsong ena, likhoele tsa cellulose li tšoaroa ka sodium hydroxide ho etsa alkali cellulose. Joale ethylene oxide e eketsoa motsoakong, o kopanang le selulose ho etsa hydroxyethyl cellulose. Qetellong, methyl chloride e kenyelletsoa motsoako ho etsa HEMC.

HEMC e sebelisoa mefuteng e mengata ea likopo, ho kenyeletsoa kaho, lijo, tlhokomelo ea botho, le meriana. E 'ngoe ea litšebeliso tsa mantlha tsa HEMC ke kahong, moo e sebelisoang lihlahisoa tse fapaneng joalo ka lirekere tse omeletseng, li-putty, likhomaretsi tsa lithaele le lihlahisoa tsa gypsum.

Ka har'a seretse se omeletseng sa motsoako, HEMC e sebelisoa e le sekontiri, se tlamang le ho boloka metsi. E thusa ho ntlafatsa ho sebetsa ha seretse le ho lumella taolo e ntle ea metsi. Sena ke sa bohlokoa hobane metsi a seretse a ama ho tsitsa ha oona, ho beha nako le matla a ho qetela.

Li-putty, HEMC e sebelisoa haholo-holo e le sekontiri le se tlamang. Ho eketsoa ha HEMC ho motsoako ho thusa ho ntlafatsa ts'ebetso ea putty le ho lumella ho laola hantle metsi. HEMC e boetse e thusa ho thibela ho arohana ha likarolo tse fapa-fapaneng tsa ho hlophisoa ha putty, 'me e ntlafatsa ho khomarela putty ho substrates.

Ka li-adhesives tsa lithaele, HEMC e sebelisoa haholo-holo e le moemeli oa ho boloka metsi. Ho eketsoa ha HEMC ho motsoako ho thusa ho ntlafatsa ts'ebetso ea sekhomaretsi le ho lumella ho laola hantle ha metsi. HEMC e boetse e thusa ho thibela ho arohana ha likarolo tse fapa-fapaneng ka mokhoa oa ho khomarela, 'me e ntlafatsa ho khomarela sekhomaretsi ho substrates.

Lihlahisoa tsa gypsum, HEMC e sebelisoa e le ntho e teteaneng, e kopanyang, le ho boloka metsi. E thusa ho ntlafatsa ts'ebetso ea sehlahisoa sa gypsum mme e lumella taolo e ntle ea metsi. Sena ke sa bohlokoa hobane metsi a sehlahisoa sa gypsum a ama nako ea eona ea ho beha le matla a ho qetela.

Ka lihlahisoa tsa lijo, HEMC e atisa ho sebelisoa e le setenya, stabilizer le emulsifier. E sebelisoa mefuteng e mengata e fapaneng ea lihlahisoa tsa lijo, ho kenyelletsa li-sauces, li-dresses le lihlahisoa tsa lebese. HEMC e nkoa e le ea bohlokoa ka lebaka la bokhoni ba eona ba ho ntlafatsa sebopeho le botsitso ba lihlahisoa tsena.

Lihlahisoang tsa tlhokomelo ea motho, HEMC e sebelisoa e le motenya, stabilizer le emulsifier. E sebelisoa mefuteng e mengata e fapaneng ea lihlahisoa tsa tlhokomelo ea motho, ho kenyelletsa li-shampoo, li-conditioner le litlolo. HEMC e nkoa e le ea bohlokoa ka lebaka la bokhoni ba eona ba ho ntlafatsa sebopeho le botsitso ba lihlahisoa tsena.

Litlhare, HEMC e sebelisoa e le tlamahano le ho senya. E sebelisoa mefuteng ea matlapa ho ntlafatsa matla a mochine le ho thusa ho senyeha le ho senyeha ha letlapa 'meleng.
