Quaternized hydroxyethyl cellulose

Quaternized hydroxyethyl cellulose (QHEC) ke phetolelo e fetotsoeng ea hydroxyethyl cellulose (HEC) e 'nileng ea itšoara ka motsoako oa quaternary ammonium. Phetoho ena e fetola thepa ea HEC 'me e fella ka polymer ea cationic e nang le mefuta e mengata ea likopo, ho kenyelletsa le lihlahisoa tsa tlhokomelo ea botho, masela le liaparo tsa pampiri.

The quaternization ea HEC e kenyelletsa ho eketsoa ha motsoako oa quaternary ammonium ho molek'hule ea HEC, e hlahisang tefiso e ntle ho polymer. Motsoako o sebelisoang haholo oa quaternary ammonium bakeng sa morero ona ke 3-chloro-2-hydroxypropyl trimethylammonium chloride (CHPTAC). Motsoako ona o sebetsana le lihlopha tsa hydroxyl molek'hule ea HEC, e hlahisang molek'hule ea QHEC e qosoang hantle.

E 'ngoe ea likopo tsa mantlha tsa HEC ke lihlahisoa tsa tlhokomelo ea motho, joalo ka li-shampoo, li-conditioner le lihlahisoa tsa setaele sa moriri. HEC e fana ka thepa e ntle ea ho lokisa le ho senya moriri, ho etsa hore ho be bonolo ho okama le ho seta. HEC e boetse e sebelisoa e le mofetoleli o motenya le oa rheology lihlahisoa tsena, e fana ka sebopeho se majabajaba le ho ntlafatsa ts'ebetso ka kakaretso.

Lits'ebetsong tsa masela, HEC e sebelisoa e le sesebelisoa sa boholo bakeng sa k'hothone le likhoele tse ling tsa tlhaho. HEC e ka ntlafatsa ho satalla le ho hanyetsa ha masela a masela, ho etsa hore e be nako e telele le e bonolo ho sebetsana le eona nakong ea ts'ebetso ea tlhahiso. HEC e ka boela ea ntlafatsa ho khomarela lidae le lisebelisoa tse ling tsa ho qeta lesela, e leng se etsang hore ho be le mebala e khanyang le ho potlakisa ho hlatsoa hantle.

HEC e boetse e sebelisoa ka ho roala pampiri ho ntlafatsa ho thibela metsi le ho hatisoa ha pampiri. HEC e ka ntlafatsa sekhomaretsi sa ho roala le ho fokotsa ho kenella ha metsi le enke ka har'a likhoele tsa pampiri, e leng se etsang hore ho be le likhatiso tse matla le tse matla haholoanyane. HEC e ka boela ea fana ka boreleli bo botle ba holim'a metsi le ho benya pampiring, ho ntlafatsa ponahalo ea eona le thepa ea tactile.

E 'ngoe ea melemo e ka sehloohong ea HEC ke tlhaho ea eona ea cationic, e etsang hore e sebetse haholo litlhahlobong tse nang le li-anionic surfactants. Li-surfactants tsa anionic li atisa ho sebelisoa lihlahisoa tsa tlhokomelo ea botho, empa li ka sebelisana le li-thickeners tse seng tsa ionic, tse kang HEC, le ho fokotsa katleho ea tsona. HEC, ho ba cationic, e ka theha litšebelisano tse matla tsa electrostatic le li-surfactants tsa anionic, tse hlahisang ntlafatso e ntlafetseng le botsitso.

Molemo o mong oa HEC ke ho lumellana ha eona le mefuta e mengata ea lisebelisoa tse ling. HEC e ka sebelisoa le lisebelisoa tse ling tsa cationic, anionic, le tse seng tsa ionic ntle le ho ama ts'ebetso ea eona. Sena se etsa hore e be motsoako o fapaneng o ka sebelisoang mefuteng e mengata ea litlhahlobo le lisebelisoa.

HEC e fumaneha ka limaraka tse fapaneng le li-viscosities, ho itšetlehile ka litlhoko tse khethehileng tsa kopo le ho etsoa. Hangata e fanoa e le phofo e ka qhalakantsoeng habonolo ka metsing kapa li-solvents tse ling. QHEC e ka boela ea fanoa e le sehlahisoa se se nang lehlakore kapa se ikemetseng, se felisang tlhokahalo ea mehato e eketsehileng ea ho se nke lehlakore nakong ea ho etsoa.

Ka bokhuts'oane, quaternized hydroxyethyl cellulose ke mofuta o fetotsoeng oa hydroxyethyl cellulose o abiloeng ka motsoako oa quaternary ammonium. HEC ke polymer ea cationic e nang le mefuta e mengata ea lits'ebetso, ho kenyeletsoa lihlahisoa tsa tlhokomelo ea motho ka mong, masela le liaparo tsa pampiri. HEC e fana ka thepa e ntle ea boemo bo botle le e teteaneng, e ntlafatsa ts'ebetso ea li-anionic surfactants, 'me e lumellana le mefuta e mengata ea lisebelisoa tse ling. Ho feto-fetoha ha maemo le ts'ebetso ea HEC e etsa hore e be motsoako oa bohlokoa mekhoeng le lits'ebetsong tse fapaneng.
