Hydroxy Ethyl Cellulose (HEC) - ho cheka oli

Hydroxyethyl cellulose (HEC) e fumana lits'ebetso liindastering tse fapaneng, ho kenyeletsoa le lekala la ho cheka oli.Ho cheka oli, HEC e sebeletsa merero e mengata ka lebaka la thepa ea eona e ikhethang.Mona ke kamoo HEC e sebelisoang kateng ho cheka oli:

1. Viscosifier: HEC e sebelisoa e le viscosifier ho maro a ho cheka ho laola rheology le ho ntlafatsa thepa ea mokelikeli.Ka ho fetola mahloriso a HEC, viscosity ea mokelikeli oa ho cheka e ka etsoa ho finyella litlhoko tse khethehileng, tse kang ho boloka botsitso ba lesoba, ho jara li-cuttings tsa ho cheka, le ho laola tahlehelo ea mokelikeli.
2. Taolo ea Tahlehelo ea Mokelikeli: HEC e sebetsa e le moemeli oa ho laola tahlehelo ea mokelikeli ka maro a ho cheka, ho thusa ho fokotsa tahlehelo ea mokelikeli ho thehoa.Thepa ena e bohlokoa bakeng sa ho boloka botsitso ba seliba, ho thibela tšenyo ea sebopeho, le ho ntlafatsa bokhoni ba ho cheka.
3. Suspension Agent: HEC e thusa ho emisa le ho jara likotoana tsa ho phunya le lintho tse tiileng ka har'a mokelikeli oa ho cheka, ho thibela ho tsitsa le ho netefatsa ho tlosoa hantle ho tsoa selibeng.Sena se thusa ho boloka botsitso ba seliba le ho thibela mathata a kang peipi e khomaretsoeng kapa ho khomarela ka tsela e fapaneng.
4. Thickener: HEC e sebetsa e le ntho e tiisang ho cheka metsoako ea seretse, ho eketsa viscosity le ho ntlafatsa ho fanyeha ha lintho tse tiileng.Mehaho e matlafalitsoeng ea ho tenya e kenya letsoho ho hloekiseng mekoti hantle, ho ntlafala ha mekoti, le ts'ebetso ea ho cheka hantle.
5. Matlafatso a Matlafalitsoeng: HEC e ka ntlafatsa lubricity marong a ho cheka, ea fokotsa likhohlano lipakeng tsa khoele ea ho cheka le mabota a seliba.Lubrication e ntlafalitsoeng e thusa ho fokotsa torque le ho hula, ho ntlafatsa ts'ebetso ea ho cheka, le ho lelefatsa bophelo ba lisebelisoa tsa ho cheka.
6. Ho tsitsa ha Mocheso: HEC e bonts'a botsitso bo botle ba mocheso, ho boloka thepa ea eona ea rheological holim'a mefuta e mengata ea mocheso e fumanoang nakong ea ts'ebetso ea ho cheka.Sena se etsa hore e loketse ho sebelisoa libakeng tse tloaelehileng le tse phahameng tsa mocheso.
7. E Setsoalle le Tikoloho: HEC e khona ho bola le ho silafatsa tikoloho, e leng se etsang hore e tšoanelehe ho sebelisoa libakeng tseo ho chekoang ho tsona tse nang le bothata ba tikoloho.Sebopeho sa eona se se nang chefo le tšusumetso e tlase ea tikoloho li kenya letsoho mekhoeng e tsitsitseng ea ho cheka.

HEC e bapala karolo ea bohlokoa ts'ebetsong ea ho cheka oli ka ho fana ka taolo ea viscosity, taolo ea tahlehelo ea mokelikeli, ho emisa, ho teteaneng, ho tlotsa, botsitso ba mocheso le ho lumellana ha tikoloho.Mehaho ea eona e feto-fetohang e etsa hore e be tlatsetso ea bohlokoa marong a ho cheka, e kenyang letsoho mekhoeng ea ho cheka e bolokehileng, e sebetsang hantle le e ikarabellang tikolohong.
