Phello ea Hydroxyethyl Cellulose holim'a Liphahlo tse tsamaeang ka Metsi

Hydroxyethyl cellulose (HEC)ke tlatsetso e sebelisoang haholo liphahlong tse nang le metsi ka lebaka la ho feto-fetoha ha eona le katleho ea ho ntlafatsa thepa e fapaneng.

1. Phetoho ea Rheology:

HEC e atisa ho sebelisoa e le mofetoleli oa rheology liphahlo tse tsoang metsing. Ka ho lokisa mahloriso a HEC, hoa khoneha ho laola viscosity le boitšoaro ba ho phalla ha thepa ea ho roala. Sena se bohlokoa bakeng sa lits'ebetso tse joalo ka brushability, sprayability, le rolara ea ho roala. HEC e fana ka boitšoaro ba pseudoplastic ho liphahlo, ho bolelang hore viscosity e fokotseha tlas'a ho kuta, ho nolofatsa kopo, ha ho ntse ho boloka ho hanyetsa ha sag hang ha matla a ho kuta a tlosoa.

2. Thixotropy:

Thixotropy ke thepa e 'ngoe ea bohlokoa ka ho roala, e buang ka boitšoaro bo fokolang ba ho kuta. HEC e fana ka thepa ea thixotropic ho liaparo tse nang le metsi, ho li lumella hore li fokotsehe tlas'a tšusumetso ea ho kuta nakong ea kopo, ho etsa bonnete ba hore li hasana hantle, ebe li teteana holim'a ho ema, e leng ho thibelang ho theoha le ho rotha holim'a libaka tse otlolohileng.

3. Botsitso:

Botsitso ke karolo ea bohlokoa ea liphahlo tse nang le metsi, kaha li tlameha ho lula li tšoana nakong ea polokelo le tšebeliso. HEC e kenya letsoho ho tsitsang ha liphahlo ka ho thibela pigment ho rarolla le ho arohana ha mekhahlelo. Phello ea eona e teteaneng e thusa ho emisa likaroloana tse tiileng ka ho lekana ho pholletsa le matrix a ho roala, ho netefatsa ts'ebetso e tsitsitseng ha nako e ntse e ea.

4. Tlhahiso ea lifilimi:

HEC e ka susumetsa mokhoa oa ho theha filimi ka liaparo tse nang le metsi. E sebetsa e le thuso ea ho etsa filimi, e ntlafatsa ho kopana ha likaroloana tsa polymer nakong ea ho omisa. Sena se fella ka hore ho thehoe filimi e tsoelang pele, e ts'oanang le ho khomarela ho matlafalitsoeng ho substrate. Ho feta moo, HEC e ka fokotsa tšekamelo ea liphahlo ho petsoha kapa blister ha e omisoa ka ho khothaletsa sebopeho se nepahetseng sa filimi.

5. Paballo ea Metsi:

Hangata liaparo tse nang le metsi li na le likarolo tse sa tsitsang tse fetohang mouoane nakong ea ho omisa, e leng se lebisang ho fokotseng le mefokolo e ka hlahang filiming ea ho roala. HEC e thusa ho boloka metsi ka har'a sebopeho sa ho roala, ho liehisa mokhoa oa ho omisa le ho khothaletsa mouoane o tšoanang. Sena se matlafatsa bots'epehi ba filimi, se fokotsa ho honyela, 'me se fokotsa kotsi ea likoli joalo ka masoba kapa cratering.

6. Ho khomarelana le Momahano:

Ho khomarela le ho kopanngoa ke lintho tsa bohlokoa bakeng sa ts'ebetso ea liaparo. HEC e ntlafatsa ho khomarela ka ho khothalletsa ho kolobisa ka mokhoa o nepahetseng le ho hasana holim'a substrate, ho etsa bonnete ba hore ho kopana ho haufi-ufi pakeng tsa ho roala le substrate. Ho feta moo, phello ea eona e teteaneng e ntlafatsa momahano ka har'a matrix a ho roala, e leng se fellang ka thepa e ntlafetseng ea mechine e kang matla a thata le ho hanyetsa abrasion.

7. Ho lumellana:

HEC e bonts'a ts'ebelisano e ntle le mefuta e mengata ea ho roala, ho kenyelletsa le li-acrylics, epoxies, polyurethanes, le alkyds. E ka kenngoa habonolo ka har'a liaparo tse nang le metsi ntle le ho baka karohano ea mekhahlelo kapa mathata a ho lumellana. Ho feto-fetoha hona ho etsa hore HEC e be khetho e ratoang bakeng sa baetsi ba lihlahisoa ba batlang ho ntlafatsa ts'ebetso ea liphahlo tsa bona.

8. Melemo ea Tikoloho:

Liaparo tse nang le metsi li ratoa ka lebaka la tšusumetso ea tsona e fokolang ea tikoloho ha li bapisoa le mekhoa e meng e thehiloeng ho solvent. HEC e tsoela pele ho kenya letsoho molemong oa ho boloka tikoloho ka ho etsa hore ho be le liphahlo tse nang le maemo a fokotsehileng a metsoako ea lintho tse phelang (VOCs). Sena se thusa baetsi ba liphahlo ho latela litlhoko tsa taolo le ho fihlela tlhoko ea bareki bakeng sa lihlahisoa tse sebetsang hantle ka tikolohong.

hydroxyethyl cellulosee fana ka melemo e mengata ho liaparo tse nang le metsi, ho kenyelletsa le phetoho ea rheology, thixotropy, botsitso, sebopeho sa filimi, ho boloka metsi, ho khomarela, ho kopana, ho lumellana, le ho boloka tikoloho. Mehaho ea eona e feto-fetohang e etsa hore e be tlatsetso ea bohlokoa bakeng sa ho fihlela litšoaneleho tse lakatsehang tsa ts'ebetso ka har'a lits'ebetso tse fapaneng tsa metsi.
