HEC bakeng sa Pente

Hydroxyethyl cellulose (HEC) ke tlatsetso e sebelisoang haholo indastering ea pente, e nkoang e le ea bohlokoa bakeng sa thepa ea eona e feto-fetohang e kenyang letsoho ho thehoeng, ho sebelisoa le ts'ebetsong ea mefuta e fapaneng ea lipente. Mona ke kakaretso ea lits'ebetso, mesebetsi, le maikutlo a HEC molemong oa ho etsa pente:

1. Kenyelletso ea Hydroxyethyl Cellulose (HEC) ka Lipente

1.1 Tlhaloso le Mohloli

Hydroxyethyl cellulose ke polima e qhibilihang ka metsing e tsoang ho selulose ka karabelo ea ethylene oxide. Hangata e tsoa ho makhasi a lehong kapa k'hothone 'me e sebetsoa ho etsa polima e nang le thepa e fapaneng ea viscosifying le ea ho etsa lifilimi.

1.2 Seabo ho Liqapi tsa Pente

Ha ho etsoa pente, HEC e sebeletsa merero e mengata, ho kenyelletsa ho tenya pente, ho ntlafatsa sebopeho sa eona, ho fana ka botsitso, le ho ntlafatsa ts'ebeliso le ts'ebetso ka kakaretso.

2. Mesebetsi ea Hydroxyethyl Cellulose ka Lipente

2.1 Mofetoleli oa Rheology le Thickener

HEC e sebetsa e le rheology modifier le thickener mefuteng ea pente. E laola viscosity ea pente, e thibela ho lokisoa ha mebala, le ho netefatsa hore pente e na le botsitso bo nepahetseng bakeng sa kopo e bonolo.

2.2 Setsibotsi

Joaloka stabilizer, HEC e thusa ho boloka botsitso ba ho etsoa ha pente, ho thibela ho arohana ha mekhahlelo le ho boloka homogeneity nakong ea polokelo.

2.3 Paballo ea Metsi

HEC e ntlafatsa thepa ea ho boloka metsi ea pente, e thibela ho omella kapele. Sena ke sa bohlokoa ka ho khetheha lipenteng tse thehiloeng metsing, tse lumellang ho sebetsa hantle le ho fokotsa litaba tse kang li-roller marks.

2.4 Thepa ea ho Etsa Lifilimi

HEC e kenya letsoho ho thehoeng ha filimi e tsoelang pele le e ts'oanang holim'a metsi a pentiloeng. Filimi ena e fana ka nako e telele, e matlafatsa ho khomarela, 'me e ntlafatsa ponahalo ea kakaretso ea bokaholimo ba pente.

3. Likopo ho Lipente

3.1 Lipente tsa Latex

HEC e atisa ho sebelisoa ka lipente tsa latex kapa tsa metsi ho laola viscosity, ho ntlafatsa botsitso ba pente, le ho ntlafatsa ts'ebetso ea eona ka kakaretso nakong ea kopo le ho omisa.

3.2 Lipente tsa Emulsion

Ka lipente tsa emulsion, tse nang le likaroloana tsa pigment tse qhalakaneng ka metsing, HEC e sebetsa e le stabilizer le thickener, e thibelang ho rarolla le ho fana ka ts'ebetso e lakatsehang.

3.3 Mekhabiso ea Motsoako

HEC e sebelisoa ka liphahlo tse entsoeng ka masela ho ntlafatsa sebopeho le ho tsitsisa ha thepa ea ho roala. E thusa ho theha sebopeho se ts'oanang le se khahlehang holim'a bokaholimo bo pentiloeng.

3.4 Li-Primer le Li-Sealers

Ho li-primers le sealers, HEC e kenya letsoho ho tsitsitseng ha moralo, taolo ea viscosity, le thepa ea ho etsa lifilimi, ho netefatsa hore ho lokisoa ha substrate ka katleho.

4. Mehato le Litlhokomelo

4.1 Ho lumellana

HEC e lokela ho lumellana le lisebelisoa tse ling tsa pente ho qoba litaba tse kang ho fokotseha ha katleho, ho phalla, kapa liphetoho mokhoeng oa pente.

4.2 Ho tsepamisa maikutlo

Motsoako oa HEC mefuteng ea pente e hloka ho laoloa ka hloko ho finyella lintho tse lakatsehang tsa rheological ntle le ho ama hampe likarolo tse ling tsa pente.

4.3 pH Boikutlo

Le hoja HEC ka kakaretso e tsitsitse ka mefuta e mengata ea pH, ho bohlokoa ho nahana ka pH ea pente ea ho etsa pente ho netefatsa ts'ebetso e nepahetseng.

5. Qetello

Hydroxyethyl cellulose ke tlatsetso ea bohlokoa indastering ea pente, e kenya letsoho ho thehoeng, botsitsong le ts'ebelisong ea mefuta e fapaneng ea lipente. Mesebetsi ea eona e feto-fetohang e etsa hore e tšoanelehe bakeng sa lipente tse thehiloeng metsing, lipente tsa emulsion, le litlolo tse entsoeng ka letsoho, har'a tse ling. Baetsi ba liforomo ba lokela ho nahana ka hloko ho lumellana, ho tsepamisa mohopolo, le pH ho netefatsa hore HEC e eketsa melemo ea eona mekhoeng e fapaneng ea pente.
