Hydroxyethyl cellulose (HEC) ichena kana yakareruka yero, isina kunhuhwirira, isina-chepfu fibrous kana powdery solid, iyo inogadzirwa ne etherification reaction yealkaline cellulose uye ethylene oxide (kana chlorohydrin).Nonionic soluble cellulose ethers.Sezvo HEC ine zvinhu zvakanaka zvekukora, kumisa, kuparadzira, emulsifying, kusungirirana, kugadzira firimu, kuchengetedza unyoro nekupa inodzivirira colloid, yakashandiswa zvakanyanya mukuongorora kwemafuta, machira, kuvaka, mishonga, chikafu, machira, kugadzira mapepa uye polymerization. nemimwe minda.40 mesh sieving rate ≥ 99%;
Chitarisiko: chena kusvika kuchiedza yero fibrous kana powdery yakasimba, isiri-chepfu, isina kunaka, inonyungudika mumvura.Insoluble mune zvakajairika organic solvents.
Hydroxyethyl cellulosethickener
Iyo viscosity inoshanduka zvishoma muhuwandu hwePH kukosha 2-12, asi viscosity inoderera kupfuura iyi chiyero.Iine maitiro ekukora, kumisa, kusunga, emulsifying, kuparadzira, kuchengetedza unyoro uye kudzivirira colloid.Mhinduro mumhando dzakasiyana dze viscosity dzinogona kugadzirirwa.Kusagadzikana pasi pekupisa kwakajairika uye kumanikidzwa, kudzivirira hunyoro, kupisa, uye kupisa kwakanyanya, uye kuve nekunyungudika kwemunyu kune dielectrics, uye mhinduro yayo ine aqueous inobvumira kuwanda kwemunyu kuti urambe wakagadzikana.
Zvinhu zvakakosha:
Senge isiri-ionic surfactant, hydroxyethyl cellulose ine zvinotevera zvimiro mukuwedzera mukukora, kumisa, kusunga, kuyangarara, kuumba firimu, kuparadzira, kuchengetedza mvura uye kupa inodzivirira colloid:
1. HEC inonyungudika mumvura inopisa kana mvura inotonhora, uye hairegi pakupisa kwepamusoro kana kufashaira, kuitira kuti ive nemhando dzakasiyana-siyana dzekunyungudika uye viscosity maitiro, uye kwete-thermal gelation;
2. Haisi-ionic uye inogona kugarisana nemamwe akawanda-anonyungudika emvura mapolymers, surfactants, uye munyu.Iyo yakanakisa colloidal thickener ye-high-concentration electrolyte mhinduro;
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 kukwanisa kwekudzivirira kwecolloid ndiyo yakasimba.
Nzvimbo yekushandisa

Product Performance
1. HEC inonyungudika mumvura inopisa kana mvura inotonhora, uye hairegi pakupisa kwepamusoro kana kufashaira, kuitira kuti ive nemhando dzakasiyana-siyana dzekunyungudika uye viscosity maitiro, uye kwete-thermal gelation;
2. Haisi-ionic uye inogona kugarisana nemamwe mapolymers anonyungudika nemvura, surfactants uye munyu mune zvakasiyana-siyana.Iyo yakanakisa colloidal thickener yemhinduro dzine yakakwira-concentration dielectrics;
3. Kukwanisa kuchengetedza mvura kwakapetwa kaviri kupfuura yemethyl cellulose, uye ine zviri nani kuyerera kwemutemo;
4. Kuenzaniswa neyakazivikanwa methyl cellulose uye hydroxypropyl methyl cellulose, kukwanisa kuparadzira kweHEC ndiyo yakaipisisa, asi kukwanisa kwekudzivirira kwecolloid ndiyo yakasimba.

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 se pigments, kuparadzira rubatsiro, ammonia mvura.
5. Shingairira kusvikira yose hydroxyethyl cellulose yakanyungudutswa zvachose (iyo viscosity yemhinduro inowedzera zvakanyanya) isati yawedzera zvimwe zvikamu mukugadzirisa, uye kugaya kusvikira chigadzirwa chapera.
