Tlhahlobo ea Tshebetso ea Lihlahisoa tsa Hydroxyethyl Cellulose

Selelekela:

Lihlahisoa tsa Hydroxyethyl Cellulose (HEC) li fumane khahleho e kholo liindastering ka lebaka la lits'ebetso tsa tsona tse feto-fetohang le thepa e ikhethang. Tlhahlobo ena ea ts'ebetso e ikemiselitse ho lekola katleho ea lihlahisoa tsa HEC mefuteng le liindastering tse fapaneng, ho shebana le matšoao a bohlokoa a ts'ebetso joalo ka ho teteana, botsitso, ho lumellana le ts'ebetso.

1. Litšobotsi tsa ho teteana le ho teteana:

·Lihlahisoa tsa HEC li tumme ka bokhoni ba tsona bo ikhethang ba ho tenya, e leng se etsang hore li be tsa bohlokoa haholo mefuteng e hlokang taolo ea viscosity. Tshebetso e hlahlojoa ho latela bokhoni ba HEC ba ho fihlela le ho boloka maemo a viscosity a reretsoeng ho pholletsa le sekhahla le mocheso o fapaneng oa ho kuta.

·Mekhoa ea liteko e kenyelletsa litekanyo tsa viscometer tse sebelisang li-viscometer tse potolohang kapa li-rheometer tlas'a maemo a fapaneng ho lekola boitšoaro ba ho fokotsa ho kuta le boemo ba viscometer ka kakaretso ba litharollo tsa HEC.

2. Botsitso le Bophelo ba Shelefo:

·Ho tsitsa ha dihlahiswa tsa HEC ho bohlokwa bakeng sa ho boloka botshepehi le tshebetso ya dihlahiswa ha nako e ntse e ya. Tlhahlobo ya tshebetso e kenyeletsa ho hlahloba botsitso ba mmele le ba dikhemikhale ba ditharollo tsa HEC tlasa maemo a fapaneng a polokelo, ho kenyeletswa mocheso, pH, le ho pepesehela lesedi le moya.

·Liteko tse potlakileng tsa botsitso le lithuto tsa botsitso tsa nako ea sebele li etsoa ho beha leihlo liphetoho tsa viscosity, ponahalo, le liparamente tse ling tse amehang ka nako e telele ho fumana nako ea ho boloka le likhothaletso tsa polokelo.

3. Ho lumellana le ho tenyetseha ha sebopeho:

·Lihlahisoa tsa HEC li lokela ho bonts'a ho lumellana le mefuta e mengata ea metsoako e sebelisoang hangata mefuteng, ho kenyeletsoa le li-surfactant, li-solvents le metsoako e sebetsang. Tlhahlobo ea ts'ebetso e kenyelletsa tlhahlobo ea ho lumellana ka liteko tsa ho kopanya ho lekola tšusumetso ea HEC botsitsong ba sehlahisoa, ponahalong le ts'ebetsong.

·Teko ea ho lumellana e ka kenyelletsa tlhahlobo ea pono, lithuto tsa karohano ea mekhahlelo, le liteko tsa ts'ebetso ho khetholla likamano kapa ho se lumellane hofe kapa hofe pakeng tsa HEC le likarolo tse ling tsa tlhahiso.

4. Tshebetso Ditshebedisong tse Ikgethang:

·Tlhahlobo ea ts'ebetso ea lihlahisoa tsa HEC e atoloha ho lits'ebetso tse itseng le liindasteri moo HEC e bapalang karolo ea bohlokoa. Sena se kenyelletsa metsoako e kang lipente, lipente, likhomaretsi, lihlahisoa tsa tlhokomelo ea botho, meriana le thepa ea kaho.

·Teko ea ts'ebetso e kenyelletsa ho lekola ts'ebetso ea metsoako e nang le HEC maemong a sebele, joalo ka ho thehoa ha filimi, matla a sekhomaretsi, boitšoaro ba rheological, kinetics ea ho lokolloa ha lithethefatsi, le litšobotsi tsa ts'ebeliso.

5. Maikutlo a Bareki le Kamohelo ea 'Maraka:

·Ditshwaelo tsa bareki le kamohelo ya mmaraka di sebetsa e le matshwao a bohlokwa a tshebetso ya sehlahiswa sa HEC ditshebedisong tse sebetsang. Ditshwaelo tse tswang ho basebedisi ba ho qetela, baqapi, le bahlahisi di fana ka temohisiso mabapi le katleho, boiketlo ba tshebediso, le kgotsofalo ka kakaretso ka dihlahiswa tsa HEC.

·Patlisiso le diphuputso tsa mmaraka di ka etswa ho lekanya dikgethollo tsa bareki, mekgwa le maikutlo mabapi le dihlahiswa tsa HEC, ho thusa ho hlwaya dibaka tsa ntlafatso le ntshetsopele ya sehlahiswa nakong e tlang.

Qetello:

Lihlahisoa tsa Hydroxyethyl Cellulose li bonts'a ts'ebetso e ikhethang ho pholletsa le mefuta e mengata ea lits'ebetso, ka lebaka la thepa ea tsona e ntle ea ho tenya, botsitso, ho lumellana le ts'ebetso. Ka tlhahlobo e matla ea ts'ebetso e kenyeletsang ho teteana, botsitso, ho lumellana le litlhoko tse ikhethileng tsa ts'ebeliso, lihlahisoa tsa HEC li tsoela pele ho fana ka ts'ebetso e phahameng le ts'epo, ho fihlela litlhoko tse fapaneng tsa liindasteri le bareki lefatšeng ka bophara. Maiteko a tsoelang pele a lipatlisiso le nts'etsopele a ikemiselitse ho ntlafatsa mekhoa ea HEC le ho atolosa lits'ebetso tsa bona, ho netefatsa boqapi bo tsoelang pele le bokhabane lihlahisoa tse thehiloeng ho HEC.
