Moemeli oa Thickening ea Metsi Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose(HEC) ke polima e qhibilihang ka metsing e tsoang ho cellulose, polima ea tlhaho e fumanoang limela. Hangata e sebelisoa e le moemeli o teteaneng ka har'a liaparo tse nang le metsi ka lebaka la thepa ea eona ea rheological, botsitso, le ho lumellana le mekhoa ea metsi. Mona ho shebisisa HEC e le ntho e tiisang liphahlo tse tsamaisoang ke metsi:

Tshebetso le Thepa:

1. Ho teteana: HEC e sebetsa haholo ho eketsa viscosity ea litharollo tsa metsi, ho kenyelletsa le liphahlo tse tsamaisoang ke metsi. Ka ho eketsa viscosity, HEC e ntlafatsa ho phalla le ho leka-lekanya litšobotsi tsa liphahlo, ho ntlafatsa thepa ea bona ea kopo, le ho thibela ho theoha kapa ho rotha.
2. Boitšoaro ba ho kuta moriri: HEC e bonts'a boitšoaro ba ho kuta, ho bolelang hore viscosity ea eona e fokotseha tlas'a khatello ea ho kuta (mohlala, nakong ea kopo), e lumellang hore ho be bonolo ho sebelisa le ho hasana ha seaparo. Ka mor'a hore khatello ea ho kuta e tlosoe, viscosity e hlaphoheloa kapele, e boloka botenya bo lakatsehang le botsitso ba ho roala.
3. Botsitso: HEC e fana ka botsitso ho liaparo tse nang le metsi ka ho thibela ho lokisa li-pigments le likarolo tse ling tse tiileng. E thusa ho boloka ho hasana ho tšoanang ha likaroloana ho pholletsa le tlhahiso ea ho roala, ho netefatsa ts'ebetso e tsitsitseng le ponahalo.
4. Ho lumellana: HEC e lumellana le mefuta e mengata e fapaneng ea metsoako ea ho roala, ho kenyelletsa le li-pigment, li-filler, li-binders le li-additives. Ha e ame hampe ts'ebetso kapa thepa ea likarolo tse ling ha ho etsoa.
5. Ho Boloka Metsi: HEC e ka ntlafatsa thepa ea ho boloka metsi ea liphahlo, e fokotsa sekhahla sa ho tsoa ha metsi nakong ea kopo le ho folisa. Sena se ka eketsa nako ea ho sebetsa ea ho roala le ho ntlafatsa ho khomarela substrate.
6. Tlhahiso ea lifilimi: HEC e kenya letsoho ho thehoeng ha filimi e ts'oanang le e tsoelang pele holim'a substrate ha seaparo se omella. E thusa ho ntlafatsa ho tšoarella, ho khomarela, le thepa ea mechine ea filimi e omisitsoeng ea ho roala.

Lisebelisoa:

1. Mehaho ea Mehaho: HEC e sebelisoa haholo ka lipente tse nang le metsi le liaparo tsa meralo ho laola viscosity, ho ntlafatsa thepa ea kopo, le ho ntlafatsa sebopeho sa lifilimi. E loketse ho sebelisoa ka har'a liaparo tsa ka hare le tsa ka ntle, ho kenyelletsa le li-primers, lipente tsa emulsion, liaparo tse entsoeng ka mokhoa o hlophisitsoeng, le mekhabiso e khabisitsoeng.
2. Liaparo tsa Indasteri: HEC e sebelisoa liphahlong tse fapaneng tsa indasteri, tse kang liphahlo tsa likoloi, liphahlo tsa lehong, liphahlo tsa tšepe le tse sireletsang. E thusa ho fihlela thepa ea rheological e lakatsehang, botenya ba filimi, le ponahalo ea bokaholimo lits'ebetsong tsena.
3. Lik'hemik'hale Tsa Kaho: HEC e sebelisoa lik'hemik'hale tsa kaho, tse kenyelletsang liphahlo tse thibelang metsi, li-sealants, li-adhesives le li-tile grouts. E fana ka thickening le botsitso ho metsoako ena, ho ntlafatsa tshebetso le tshebetso.
4. Liaparo tsa Pampiri: Ka liphahlo tsa pampiri le liphekolo tsa holim'a metsi, HEC e sebelisetsoa ho ntlafatsa thepa ea rheological ea litlolo tsa ho roala, ho ntlafatsa boleng ba khatiso, le ho eketsa ho tšoara enke holim'a pampiri.
5. Textile Coatings: HEC e sebelisoa ka masela a masela 'me a qeta ho fana ka ho satalla, ho leleka metsi le ho hanela masela. E thusa ho laola viscosity ea li-coating formulations le ho netefatsa ts'ebeliso e ts'oanang holim'a substrate ea masela.

hydroxyethyl cellulose (HEC) e sebetsa e le sesebelisoa se tenyetsehang le se sebetsang hantle ka har'a liphahlo tse tsamaisoang ke metsi, ho fana ka taolo ea viscosity, botsitso, ho boloka metsi, le thepa ea ho etsa filimi ea bohlokoa bakeng sa ho fihlela ts'ebetso le ponahalo e lakatsehang.
