Hydroxyethyl cellulose (HEC) ichena kana yakareruka yeyero, isinganhuhwi, isina-chepfu fibrous kana upfu hwakasimba yakagadzirwa ne etherification yealkaline cellulose uye ethylene oxide (kana chlorohydrin).Nonionic soluble cellulose ethers.Nemhaka yekuti HEC ine zvinhu zvakanaka zvakadai sekukora, kumisa, kuparadzira, emulsifying, kusungirirwa, kugadzira firimu, kuchengetedza unyoro uye kupa macolloids ekudzivirira, yakashandiswa zvakanyanya mukuchengetedza ganda, kuongorora mafuta, kuvhara, kuvaka, mishonga uye zvokudya, machira, kugadzira mapepa uye polymers.Polymerization uye mamwe minda.40 mesh sieving rate ≥ 99%;
Chimiro chechimiro: chena kusvika kuchiedza chero fibrous kana powdery yakasimba, isina-chepfu, isina kunhuwa, inonyungudika nyore mumvura.Insoluble in general organic solvents.
Hydroxyethyl cellulose
Muchikamu che PH kukosha kwe 2-12, shanduko ye viscosity iduku, asi viscosity inoderera kupfuura iyi.Iine maitiro ekukora, kumisa, kubatana, emulsifying, kuparadzira, kuchengetedza unyoro uye kudzivirira colloid.Mhinduro dzemhando dzakasiyana dze viscosity dzinogona kugadzirirwa.Iyo haina kugadzikana pasi peyakajairika tembiricha uye kumanikidzwa, kudzivirira hunyoro, kupisa uye tembiricha yakanyanya, uye ine yakasarudzika munyu mukunyungudika kune dielectrics, uye mhinduro yayo ine aqueous inobvumirwa kuve neyakawanzisa munyu uye yakagadzikana.
Zvinhu zvakakosha: Senge isiri-ionic surfactant, hydroxyethyl cellulose ine zvinotevera zvinhu mukuwedzera kukora, kumisa, kusunga, kutenderera, firimu-kuumba, kuparadzira, kuchengetedza mvura uye kupa ekudzivirira macolloid:
1. HEC inonyungudika mumvura inopisa kana inotonhora, uye haipindi pakupisa kwepamusoro kana kuvira, ichiita kuti ive nehuwandu hwekunyungudika uye viscosity maitiro, uye kwete-thermal gelation;
2. Haisi-ionic uye inogona kugarisana nemamwe akawanda-anonyungudika mapolymers, surfactants uye munyu, uye yakanakisa colloidal thickener ine high-concentration electrolyte solutions;
3. Kukwanisa kwekuchengetedza mvura kwakapetwa kaviri kune iyo yemethyl cellulose, uye ine zviri nani kuyerera kwemutemo.
4. Kuenzaniswa neyakazivikanwa methyl cellulose uye hydroxypropyl methyl cellulose, kukwanisa kuparadzira kweHEC ndiyo yakaipisisa, asi iyo inodzivirira colloid ine simba rakasimba.
Kupeta nzvimbo yekushandisa
Inoshandiswa seanonamira, surfactant, colloid inodzivirira agent, dispersant, emulsifier uye dispersion stabilizer.Iine huwandu hwakawanda hwemashandisirwo ekuputira, ingi, fiber, dhayi, papermaking, cosmetics, mishonga yekuuraya zvipembenene, mineral processing, kubvisa mafuta uye mushonga.

Basa rehydroxyethyl cellulose mumakemikari ekuumbwa kwezvizoro?Iyo inonyungudika nemvura polymer makomisheni anoshandiswa muzvizora anonyanya kukamurwa kuita mapoka maviri: echisikigo uye ekugadzira.
Natural soluble polymer compounds inosanganisira: starch, plant gum, mhuka gelatin, nezvimwewo, asi unhu husina kugadzikana, huri nyore kukanganiswa nemamiriro ekunze, nzvimbo yenharaunda, goho shoma, uye nyore nyore kuparara nebhakitiriya uye mold.
Synthetic water-soluble polymer compounds zvinosanganisira polyvinyl doro, polyvinylpyrrolidone, nezvimwewo, ine zvinhu zvakagadzikana, ganda rinopisa uye nemutengo wakaderera, saka dzakatsiva mvura yakasikwa-inonyungudika yepolymer compounds uye inova iyo huru yezvigadzirwa zve colloid.
Iyo zvakare yakakamurwa kuita semi-synthetic uye synthetic mvura-soluble polymer makomisheni.
Semi-synthetic water-soluble polymer compounds inowanzoshandiswa: methyl cellulose, ethyl cellulose, sodium carboxymethyl cellulose, hydroxyethyl cellulose, uye guar gum nezvimwe zvinobva pairi.
Synthetic water-soluble polymer compounds inowanzoshandiswa: polyvinyl doro, polyvinylpyrrolidone, acrylic acid polymer, nezvimwewo.
Aya anoshandiswa muzvizoro seanonamira, makobvu, mafirimu ekutanga, uye emulsion stabilizers.
