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.Pamusoro pekukora, kumisa, kusunga, flotation, firimu-kuumba, kuparadzira, kuchengetedza mvura uye nekupa inodzivirira colloids, ine zvinotevera zvivakwa:
1. HEC inonyungudika mumvura inopisa kana inotonhora, uye hairegi pakupisa kwepamusoro kana kuvira, kuitira kuti ive nemhando dzakasiyana-siyana dzekunyungudika uye viscosity maitiro, uye kwete-thermal gelation;
2. Iyo isiri-ionic pachayo inogona kugarisana nemamwe akawanda-anonyungudika emvura 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.Nekuti HEC ine zvinhu zvakanaka zvekukora, kumisa, kuparadzira, emulsifying, kusungirirana, kugadzira firimu, kuchengetedza unyoro nekupa inodzivirira colloid, yakashandiswa zvakanyanya mukutsvagisa mafuta, machira, kuvaka, mishonga uye chikafu, machira, mapepa uye polymerization. nemimwe minda.
Zvekungwaririra:
Sezvo iyo yepamusoro-yakagadziriswa hydroxyethyl cellulose ipfu kana cellulose yakasimba, zviri nyore kubata uye kunyungudika mumvura chero bedzi zvinhu zvinotevera zvichionekwa.
1. Pamberi uye mushure mekuwedzera hydroxyethyl cellulose, inofanira kukurudzirwa nguva dzose kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.
2. Inofanira kuvharwa mubhodhoro rinosanganiswa zvishoma nezvishoma, uye usawedzera zvakananga hydroxyethyl cellulose iyo yakaumbwa kuva mapundu uye mabhora mumusanganiswa.
3. Kupisa kwemvura uye pH kukosha kwemvura kune hukama huri pachena nekuparara kwehydroxyethyl cellulose, saka kunyanya kunofanira kubhadharwa kwairi.
4. Usambofa wakaisa chimwe chinhu chealkaline kumusanganiswa usati wehydroxyethyl cellulose poda yadziyirwa nemvura.Kusimudza kukosha kwePH mushure mekudziya kunobatsira pakuparara.
5. Sezvinobvira, wedzera antifungal agents nokukurumidza sezvinobvira.
6. Paunenge uchishandisa high-viscosity hydroxyethyl cellulose, kusanganiswa kwedoro raamai hakufaniri kunge kwakakwirira kudarika 2.5-3%, kana zvisina kudaro doro raamai richava rakaoma kubata.Iyo post-yakarapwa hydroxyethyl cellulose kazhinji haisi nyore kuumba mapundu kana mativi, uye haizogadziri insoluble spherical colloids mushure mekuwedzera mvura.
