1.1 e kentsoe ka kotloloho ka nako ea tlhahiso

1. Kenya metsi a hloekileng ka nkhong e kholo e nang le motsoako o phahameng oa ho kuta.

2. Qala ho sisinyeha ka ho tsoelang pele ka lebelo le tlaase 'me butle-butle u sefa hydroxyethyl cellulose ka tharollo e lekanang.

3. Tsoela pele ho sisinya ho fihlela likaroloana tsohle li kolobile.

4. Ebe u eketsa moemeli oa antifungal, li-additives tsa alkaline tse kang li-pigments, lithuso tse qhalakang, metsi a ammonia.

5. Hlohlelletsa ho fihlela cellulose eohle ea hydroxyethyl e qhibiliha ka ho feletseng (viscosity ea tharollo e eketseha haholo) pele u eketsa likarolo tse ling ka foromo, 'me u sila ho fihlela sehlahisoa se felile.

1.2 E lokiselitsoe ka joala ba bo-mme

Mokhoa ona ke ho lokisa joala ba 'm'e ka khatello e phahameng pele, ebe o e eketsa penteng ea latex. Molemo oa mokhoa ona ke hore o na le phetoho e kholoanyane 'me e ka kenyelletsoa ka ho toba penteng e phethiloeng, empa e lokela ho bolokoa hantle. Mehato e tšoana le Mehato ea 1-4 ho Method 1, phapang ke hore ha ho na tlhokahalo ea ho hlohlelletsa ho fihlela e qhibiliha ka ho feletseng ka tharollo ea viscous.

2.Porridge bakeng sa phenology
Ho tloha ka manyolo solvents futsanehileng solvents bakeng sahydroxyethyl cellulose, li-solvents tsena tsa tlhaho li ka sebelisoa ho lokisa motoho. Litlhapi tse sebelisoang ka ho fetisisa ke li-organic liquids tse kang ethylene glycol, propylene glycol le li-formers tsa lifilimi (tse kang ethylene glycol kapa diethylene glycol butyl acetate) ha ho etsoa pente. Metsi a leqhoa le ona ha a na solvent, kahoo metsi a leqhoa a atisa ho sebelisoa hammoho le lino tse phelang ho lokisa motoho. Selulose ea hydroxyethyl ea poro e ka kenngoa ka ho toba penteng, 'me cellulose ea hydroxyethyl e arotsoe' me ea ruruha ka har'a motoho. Ha e kenngoa penteng, e qhibiliha hang-hang 'me e sebetsa e le motenya. Ka mor'a ho eketsa, tsoela pele ho hlohlelletsa ho fihlela hydroxyethyl cellulose e qhibiliha ka ho feletseng 'me e tšoana. Ka kakaretso, motoho o etsoa ka ho kopanya likarolo tse tšeletseng tsa motsoako oa motsoako kapa metsi a leqhoa le karolo e le 'ngoe ea hydroxyethyl cellulose. Kamora metsotso e ka bang 6-30, selulose ea hydroxyethyl e tla be e entsoe ka hydrolyzed mme e ruruhe ho hlakile. Lehlabuleng, mocheso oa metsi hangata o phahame haholo, kahoo ha hoa lokela ho sebelisa motoho.

3. E sebelisoa e le sethibelo se teteaneng le sa tahlehelo ea mokelikeli bakeng sa mokelikeli oa ho cheka o thehiloeng metsing le mokelikeli o phethoang, 'me phello e teteaneng e totobetse mokelikeli oa ho phunya oa brine. E ka boela ea sebelisoa e le mokelikeli tahlehelo e fokotsang bakeng sa oli seliba samente. E ka kopanngoa le li-ion tsa tšepe tse nang le polyvalent ho etsa gel.

4. Hydroxyethyl cellulose sehlahisoa se sebelisoa e le dispersant bakeng sa polymerization ea petroleum metsi-based gel fracturing fluid, polystyrene le polyvinyl chloride, joalo-joalo ka fracturing. E ka boela ea sebelisoa e le emulsion thickener indastering ea pente, hygrostat indastering ea elektronike, anticoagulant ea samente le moemeli oa ho boloka mongobo indastering ea kaho. Ho belisoa ha indasteri ea ceramic le setlama sa sesepa sa meno. E boetse e sebelisoa haholo ho hatisa le ho daea, masela, ho etsa pampiri, meriana, bohloeki, lijo, lisakerete, chefo e bolaeang likokoanyana le lintho tse timang mollo.
