Tšebeliso ea Hydroxyethyl Cellulose ka Lipente tse Thehiloeng ka Metsi

Hydroxyethyl cellulose (HEC) ke polima e qhibilihang ka metsing e tsoang ho selulose, polima ea tlhaho e fumanoang limela. HEC e sebelisoa haholo ha ho etsoa lipente tse thehiloeng metsing ka lebaka la bokhoni ba eona ba ho sebetsa e le motenya, stabilizer le rheology modifier. Sehloohong sena, re tla tšohla thepa ea HEC, tšebeliso ea eona ka lipente tse thehiloeng metsing, le melemo eo e fanang ka eona.

Thepa ea Hydroxyethyl Cellulose

HEC ke phofo e tšoeu ho isa ho e khanyang, e sa nkhang hamonate, 'me e sa latsoeheng e qhibilihang metsing a batang le a chesang. E na le boima bo phahameng ba limolek'hule le sebopeho sa molek'hule se ts'oanang, e leng se etsang hore e be moemeli o babatsehang oa ho tenya bakeng sa lipente tse thehiloeng metsing. The viscosity ea tharollo ea HEC e eketseha ka ho eketseha ha mahloriso a eona, boima ba limolek'hule le mocheso.

HEC ke polymer e seng ea ionic, e bolelang hore ha e na tefo ea motlakase. Thepa ena e etsa hore e lumellane le mefuta e fapaneng ea li-resin le li-additives tse ling tse sebelisoang mefuteng ea pente e thehiloeng metsing. HEC e na le chefo e tlaase 'me e nkoa e sireletsehile bakeng sa tšebeliso ea lipente le lipente.

Tšebeliso ea Hydroxyethyl Cellulose Lipenteng Tse Thehiloeng Metsing

Lipente tse entsoeng ka metsi li entsoe ka metsoako e fapaneng, ho kenyelletsa li-pigment, li-resin, li-additives le metsi. Sepheo se seholo sa ho eketsa HEC ho lipente tse thehiloeng metsing ke ho fana ka taolo ea rheological, e leng bokhoni ba ho laola ho phalla le ho leka-lekanya thepa ea pente. Phello e matla ea HEC e ntlafatsa bokhoni ba pente ea ho khomarela bokaholimo, ho fokotsa marotholi le li-splatters, le ho fana ka pheletso e boreleli.

HEC e boetse e sebelisoa e le stabilizer ka lipente tse thehiloeng metsing, e bolelang hore e thusa ho thibela ho lokisoa ha li-pigments le likaroloana tse ling ha ho etsoa pente. Thepa ena e ntlafatsa ho tsitsisa ha pente mme e etsa bonnete ba hore 'mala le lisebelisoa tse ling li lula li tšoana nakong eohle ea bophelo ba sehlahisoa.

 

Melemo ea Hydroxyethyl Cellulose ka Lipente tse Thehiloeng ka Metsi

HEC e fana ka melemo e mengata ho lipente tse entsoeng ka metsi, ho kenyelletsa:

1. Phallo e Ntlafetseng le Boemo bo ntlafetseng

HEC ke mofetoleli o motle oa rheology, o fana ka phallo e ntlafalitsoeng le thepa ea boemo ho lipente tse thehiloeng metsing. Thepa ena e etsa hore e be boreleli ebile e qetelle, e etsa hore e be e loketseng ho sebelisoa lits'ebetsong tse fapaneng, ho kenyeletsoa lipente tsa lebota, lipente tsa lehong, le liphahlo tsa likoloi.

2. Molemo oa Adhesion

Phello e matla ea HEC e thusa pente ho khomarela hantle holimo, ho fokotsa kotsi ea ho rotha le splatters. Thepa ena e etsa hore HEC e be e loketseng ho sebelisoa libakeng tse bonoang haholo joalo ka mabota, siling le thepa ea ka tlung.

3. Keketseho ea Botsitso

HEC ke stabilizer e babatsehang, e thusang ho thibela ho lokisoa ha li-pigments le likaroloana tse ling ha ho etsoa pente. Thepa ena e etsa bonnete ba hore 'mala oa pente le thepa e' ngoe e lula e tšoana nakong eohle ea bophelo ba sehlahisoa, e leng se etsang hore e ipiletse ho bareki.

4. Ntlafatso ea ho tšoarella

HEC e ka ntlafatsa ho tšoarella ha lipente tse thehiloeng metsing ka ho fana ka seaparo se matla le se tšoanang. Thepa ena e etsa hore e be e loketseng ho sebelisoa libakeng tse nang le sephethephethe se phahameng, moo pente e ka senyehang le ho taboha.

5. Ho baballa tikoloho

Lipente tse thehiloeng metsing li nkoa e le tsa botsoalle ho feta lipente tse thehiloeng ho solvent hobane li ntša metsoako e fokolang ea lintho tse phelang (VOCs). HEC ke polima ea tlhaho e nkiloeng mehloling e ka nchafatsoang, e etsang hore e be khetho ea eco-friendly bakeng sa ho sebelisoa lipente tse thehiloeng metsing.

Qetello

Qetellong, HEC ke motsoako oa bohlokoa ha ho etsoa lipente tse thehiloeng metsing. Bokhoni ba eona ba ho sebetsa joalo ka motenya, botsitso, le rheology modifier bo fana ka melemo e mengata, ho kenyelletsa phallo e ntlafalitsoeng le boemo, ho khomarela hamolemo, botsitso bo eketsehileng, ho tšoarella ho matlafalitsoeng, le botsoalle ba tikoloho. Thepa e ikhethang ea HEC e e etsa khetho e nepahetseng bakeng sa ho sebelisoa lits'ebetsong tse fapaneng, ho kenyeletsoa lipente tsa lebota, lipente tsa patsi le liphahlo tsa likoloi. Tšireletseho le ho lumellana ha eona le mefuta e sa tšoaneng ea li-resin le lisebelisoa tse ling tse sebelisoang mefuteng ea pente e entsoeng ka metsi e etsa hore e be khetho e ratoang ho bahlahisi. Ho feta moo, HEC ke polima ea tlhaho e nkiloeng mehloling e tsosolositsoeng, e etsang hore e be khetho e tsitsitseng le eco-friendly bakeng sa lipente tse thehiloeng metsing.
