Hec, kapa hydroxethyl cellulouse, ke polymer ea hloileng, ea nang le metsi e qhibilihang e tsoang cellulose. Maemong a ho cheka, haholoholo ka phatlohong ea oli le khase, hec e bapala karolo ea bohlokoa ho ntlafatsa katleho ea ho chencha metsi. Maro a mangata, hangata a ne a bua ka litlolo tse fapaneng, tse khahlisang li boloka li-hydrostatic, le ho tiisa seliba.

Sebopeho sa lik'hemik'hale le thepa ea hec
Hydroxethyl Cellulouse e hlahisoa ka mokhoa oa cellulose ka oxide ea ethylene. Phello ke polymer e nang le likarolo tse kenyelletsang li-hydrophilic (ho hohela metsi) le tsa hydrophobic (ho pheta-pheta metsi). Motsoako ona o ikhethang o fana ka thepa e mengata ea bohlokoa:

Qeto ea metsi: hec e qhibiliha habonolo ka metsing a batang kapa a chesang, a theha tharollo ea colloridal.
Molefo oa liketsahalo: Ho ka eketsa viscoity ea tharollo ea metsi, ho e etsa moemeli ea bohloko haholo.
Ho tsitsa: HEC tharollo e tsitsitse ho phallo e pharaletseng (hangata ph 2-12) ebile e ka khona ho mamella letsoai le litlolo tse fapaneng.
Bokhoni ba ho etsa lifilimi: E theha lifilimi tse hlakileng, tse thata le tse feto-fetohang ha li omella.
Setsi sa se seng sa Ionic: Ho se ratehe, Hec ha se kenelle le metsoako e meng ea ionic moleng oa ho cheka, ea etsang hore o be le botsitso.

Karolo ea Hec ka ho cheka metsi
Ho taka mathela, kapa ho cheka seretse sa ho cheka, ho bohlokoa molemong oa ho cheka. Ba etsa mesebetsi e mengata ea bohlokoa, 'me kenyelletso ea Herc e ntlafatsa ts'ebetso ea bona ka litsela tse latelang.

1. Taolo ea liketsahalo tsa Viscosity
Hec o sebelisoa haholo ho cheka maro ho laola pono. Litsie tsa mokelikeli tse tahang li bohlokoa bakeng sa ho emisoa le ho tsamaisa lipalangoang. Ka ho fetola khatello ea hec, basebelisi ba sebetsang ho ka tsamaisa pono ea mokelikeli o tahiloeng ho tsamaisana le litlhoko tse ikhethileng tsa ts'ebetso e tahang. Taolo ena e thusa ho boloka katleho ea ts'ebetso ea ho chencha le ho thibela litaba tse kang seredityes of cuttings.

2. Taolo ea mofuta
Ha a cheka, ho foka, ho bua ka mokhoa oo karolo ea metsi a hohelang e haola le sebopeho se haufi, ho siea kuku e chesitsoeng. Cake e sebetsang e fokotsa tahlehelo ea mokelikeli o tahiloeng mme o tiisa seqhomane. Hec o thusa ho fokotsa sekhahla sa ho tsoala ka ho theha kuku e tšesaane e maralleng marako a mangata, a thibelang sebopeho se pharaletseng le ho tiisa sebopeho.

3. Lubrication
Hec e kenya letsoho molemong oa ho cheba maro a ho cheka. Khoele e sebetsang e fokotsa khohlano lipakeng tsa khoele ea ho cheka le sefi se nang le sefi se na le seriti sa lisebelisoa tse tahiloeng mme ho thibela maemo a ho palama. Molemong ona o molemo o motle haholo oa ho taka se kopaneng kae moo ho amanang le khoele ea ho cheka le sefifi se boleloang hantle.

4. Matlafatso ea Grebore
Ho tšepahala ha seliba ke sa bohlokoa bakeng sa ts'ebetso e bolokehileng le e sebetsang e sebetsang. Hec o thusa ho tiisa seliba sa ho fokotsa metsi a ho cheka marong, ka tsela e ka fokotsa kotsi ea ho oa hantle. Bokhoni ba eona bo etsang lifilimi bo boetse bo thusa ho tiisa masholu le liperehong tsa sebopeho, hape li kenya letsoho bohatong bo botle.

5. Mehopolo ea tikoloho le ea polokeho
Hec ke polymer e se nang chefo le e biodegradadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadadad Ts'ebeliso ea eona ea mesebetsi e chesang e thusa ho fokotsa bolo ea tikoloho, ho etsa hore ho behe mekhoa e sa sireletsehang le ho feta.

Mefuta le limaraka tsa Hec tse sebelisoang ho cheka
Ho na le limaraka tse fapaneng tsa Hec tse fumanehang, e 'ngoe le e' ngoe e tsamaisang likopo tse khethehileng le litlhoko tsa ts'ebetso. Khetho ea sehlopha se loketseng sa hec e ipapisitse le lintlha tse kang pono e lakatsehang, tsitsipano ea mocheso le maemo a itseng a ho cheha. Hangata, Hec e arotsoe ho latela boima ba eona ba limolek'hule le degree ea sebaka (tekanyo ea hydroyl e nkeloa sebaka ka lihlopha tsa hydroyethyl).

Limaraka tse phahameng tsa Viscos: sebelisoa likopo tse hlokang ntlafatso ea bohlokoa ea pono.
Limaraka tse mahareng tsa liketsahalo: Fana ka chelete e ngata lipakeng tsa pono le boiketlo ba ho sebetsana.
Mekha e tlase ea Lipapatso: E loketse maemo ao ho a fang maemo a tloaelehileng a pono.
Mekhoa ea ts'ebeliso le mekhoa e metle
Ts'ebeliso ea Hec ho maro a ho noeng ke ho hlahloba mekhoa e hlokolosi, ho kopanya le ho lumellana le lisebelisoa tse ling tsa metsi a mangata. Mekhoa e meng e metle e kenyeletsa:

Ho kopanya ka nepo: HEC butle-butle e ile ea eketsoa ka har'a mokelikeli ha e ntse e hlohlelletsa ho thibela sebopeho sa khanye le ho hlasela esita le ho hana.
Phallo ea mahloriso: Khatello ea HEC e lokela ho ntlafatsoa ho fihlela thepa e lakatsehang ntle le thipa, e ka bakang litaba tse ngata tse kang khatello e feteletseng.
Tefo ea ho etsa joalo: Pele u kenyelletsa Hec mokelikeli o mongata, ho bohlokoa ho leka ho tsamaisana le litlatsetso tse ling ho thibela karabelo ea lik'hemik'hale tse sa rateheng.

Liphephetso le Tharollo
Ha hec a fana ka melemo e mengata, ho na le mathata a amanang le tšebeliso ea eona ka metsi a ho taka:

Boikutlo ba mocheso: Visi ea Heccosity e ka angoa ke liphetoho tsa mocheso. Mocheso o phahameng o ka fokotsa pono ea tharollo ea hec, e leng ho hloka tšebeliso ea limaraka tse tsitsitseng kapa litlatsetso tse ling.
Sekhahla sa Shear: Hec a ka fetisa monko o litšila tlasa maemo a phahameng a hlakisang, a lebisang tahlehalong ea pono. U sebelisa limaraka tse tsitsitseng tsa mahlakore le ka mokhoa o nepahetseng le mekhoa e nepahetseng ea ho sebetsana le eona e ka fokotsang bothata bona.
Mehopolo ea theko ea theko: Hec e ka theko e phahameng haholo ho feta litlatsetso tse ling. Leha ho le joalo, katleho ea eona le melemo ea tikoloho e lokafatsa litšenyehelo.

Hydroxethyl Cellulose (Hec) ke karolo ea bohlokoa mabenkeleng a ho nooa, ho fana ka melemo taolong ea lifofallo, lubrication e ntle le e ntle. Mofuta oa eona o nang le chefo le biodegradable o etsa hore e be khetho e mosa ea ts'ebetso ea ho cheka. Ka ho utloisisa thepa ea eona, mekhoa ea ts'ebeliso le mathata, ba ka phallang Shec ho matlafatsa katleho le polokeho ea mesebetsi ea bona e tahang.
