Chii chinonzi Hydroxyethyl cellulose?

Hydroxyethyl cellulose (HEC) ichena kana yakareruka yero, isina kunhuhwirira, isina-chepfu fibrous kana upfu yakasimba, yakagadzirwa ne etherification reaction yealkaline cellulose uye ethylene oxide (kana chlorohydrin).
1.Mirayiridzo
1.1 yakawedzerwa zvakananga panguva yekugadzira

1. Wedzera mvura yakachena kubhaketi guru rine musanganiswa weshear wakakwirira.

2. Tanga kubvongodza uchienderera mberi nekumhanya kwakaderera uye zvishoma nezvishoma sieve hydroxyethyl cellulose mumushonga wakaenzana.

3. Ramba uchikurunga kusvikira zvimedu zvose zvanyorova.

4. Zvadaro wedzera antifungal agent, alkaline additives yakadai sepigments, kuparadzira rubatsiro, ammonia mvura.

5. Shingairira kusvikira yose hydroxyethyl cellulose yakanyungudutswa zvachose (viscosity yemhinduro inowedzera zvakanyanya) isati yawedzera zvimwe zvikamu muhutano, uye kugaya kusvikira chigadzirwa chapera.

1.2 Yakagadzirirwa nedoro raamai

Iyi nzira ndeyekugadzira doro raamai nepamusoro pekutanga, uyezve kuwedzera kune latex pendi. Kubatsira kweiyi nzira ndeyokuti ine hukuru hunochinja uye inogona kuwedzerwa zvakananga kupende yakapedzwa, asi inofanira kuchengetwa zvakanaka. Matanho acho akafanana neMatanho 1-4 muMethod 1, mutsauko ndewekuti hapana chikonzero chekubvongodza kusvikira yanyungudika zvachose mumhinduro ye viscous.

2.Porridge ye phenology
Sezvo organic solvents ari murombo zvinonyungudutsa nokudahydroxyethyl cellulose, aya organic solvents anogona kushandiswa kugadzira porridge. Iyo inonyanya kushandiswa organic solvents ndeye organic liquids yakadai se ethylene glycol, propylene glycol uye mafirimu ekare (akadai se ethylene glycol kana diethylene glycol butyl acetate) mukugadzirwa kwependi. Mvura yeaizi zvakare inonyungudutsa isina kunaka, saka mvura yechando inowanzoshandiswa pamwe chete nezvinonwiwa kugadzirwa porridge. Iyo hydroxyethyl cellulose yeporridge inogona kuwedzerwa zvakananga kupende, uye hydroxyethyl cellulose yakakamurwa uye yakaputika muporridge. Kana yawedzerwa pendi, inonyungudika pakarepo uye inoita seyakakora. Mushure mekuwedzera, ramba uchikurudzira kusvikira hydroxyethyl cellulose yanyungudutswa zvachose uye yakafanana. Kazhinji, porridge inogadzirwa nekusanganisa zvikamu zvitanhatu zveorganic solvent kana ice water nechikamu chimwe chehydroxyethyl cellulose. Mushure memaminitsi matanhatu kusvika makumi matatu, iyo hydroxyethyl cellulose ichave ine hydrolyzed uye kuzvimba zviri pachena. Muzhizha, tembiricha yemvura inowanzokwira zvakanyanya, saka haina kukodzera kushandisa porridge.
3.Application field

Hydroxyethyl cellulose Inoshandiswa seadhesives, surfactants, colloidal protective agents, dispersants, nezvimwewo.
Iine huwandu hwakasiyana hwekushandisa mupende, pendi, fiber, dhayi, kugadzira mapepa, zvizorwa, mishonga yekuuraya zvipembenene, mineral processing, mafuta ekudzoreredza vamiririri, uye mushonga.

1. Hydroxyethyl cellulose inowanzoshandiswa seyakakura, inodzivirira, inonamatira, stabilizer uye kuwedzera kwekugadzirira emulsion, jelly, mafuta, lotion, kuchenesa maziso, suppository uye tablet, uye inoshandiswawo se hydrophilic gel uye skeleton Materials, kugadzirira. matrix-mhando inosimudzira-kusunungurwa gadziriro, uye inogona zvakare kushandiswa seyakagadzika mukudya.

2. Hydroxyethyl cellulose Inoshandiswa sechinhu chinoyera muindasitiri yezvipfeko, uye sechinhu chinobatsira pakubatanidza, kukora, kukwirisa, uye kudzikamisa muchikamu chemagetsi neindasitiri yemwenje.

3. Inoshandiswa seyakakora uye inoderedza kurasikirwa kwemvura kune mvura-based drilling fluid uye kupera kwemvura, uye kukora mhedzisiro kuri pachena mune brine drilling fluid. Inogona zvakare kushandiswa semvura kurasikirwa inoderedza yemafuta tsime simende. Inogona kuchinjika-yakabatana ne polyvalent simbi ions kugadzira gel.

4. Hydroxyethyl cellulose chigadzirwa chinoshandiswa se dispersant nokuda kwepolymerization yepetroleum mvura-based gel fracturing fluid, polystyrene uye polyvinyl chloride, nezvimwewo nekuputika. Inogona zvakare kushandiswa semulsion thickener muindasitiri yependi, hygrostat muindasitiri yemagetsi, simende anticoagulant uye mumiriri wekuchengetedza mwando muindasitiri yekuvaka. Ceramic industry glazing uye mazino binder. Inoshandiswawo zvakanyanya mukudhinda nekudhaya, machira, kugadzira mapepa, mushonga, hutsanana, chikafu, fodya, mishonga yezvipembenene uye zvinodzima moto.

5. Se surfactant, colloidal protective agent, emulsification stabilizer yevinyl chloride, vinyl acetate uye mamwe emulsions, pamwe ne latex tackifier, dispersant, dispersion stabilizer, etc. Inoshandiswa zvakanyanya mukuputira, fiber, dyeing, papermaking, cosmetics, mishonga yekuuraya zvipembenene , etc. Iyo ine zvakare yakawanda inoshandiswa mukuongorora oiri uye indasitiri yemichina.

6. Hydroxyethyl cellulose ine pamusoro inoshanda, thickening, kumisa, kusunga, emulsifying, firimu-kuumba, kuparadzira, kuchengetedza mvura uye kudzivirira mabasa mumishonga yakasimba uye gadziriro yemvura.

7. Inoshandiswa se polymeric dispersant pakushandisa petroleum mvura-based gel fracturing fluid, polyvinyl chloride uye polystyrene. Inogona zvakare kushandiswa se emulsion thickener muindasitiri yependi, simende anticoagulant uye mwando kuchengetedza mumiriri muindasitiri yekuvaka, glazing agent uye mushonga wemazino anonamira muindasitiri yeceramic. Inoshandiswawo zvakanyanya mumaindasitiri akadai sekudhinda nekudhaya, machira, kugadzira mapepa, mishonga, hutsanana, chikafu, fodya nemishonga yezvipembenene.
