HEC (Hydroxyethylcellulose) inowanzoshandiswa mvura-soluble polymer ine huwandu hwakawanda hwemashandisirwo muzvigadzirwa zvemaindasitiri nevatengi, kunyanya mumajasi, zvizorwa, zvemishonga uye maindasitiri ezvekudya. Iyo hydration process yeHEC inoreva nzira iyo HEC poda inotora mvura uye inonyungudika mumvura kuti iite yunifomu mhinduro.
Zvinhu zvinokanganisa nguva ye hydration yeHEC
Nguva ye hydration yeHEC haina kugadziriswa, asi inobatwa nezvinhu zvakawanda. Kazhinji, nguva ye hydration yeHEC mumvura inogona kusiyana kubva pamaminitsi mashomanana kusvika maawa mashomanana. Izvi zvinotevera zvinhu zvikuru zvinokanganisa HEC hydration nguva:
Molecular huremu uye dhigirii rekutsiva HEC: Huremu hwemamorekuru uye dhigirii rekutsiviwa kweHEC (iyo dhigirii yekutsiva inoreva dhigirii iyo hydroxyethyl mapoka anotsiva hydroxyl mapoka mu cellulose molecule) ichakanganisa zvakanyanya hydration yayo. HEC ine uremu hwakakura hwema molecular inotora nguva yakareba kuti iite hydrate, nepo HEC ine dhigirii yepamusoro yekutsiva inoita kunge iri nani kunyungudika kwemvura uye kukurumidza kwe hydration kuchakwidziridzwa zvinoenderana.
Tembiricha yemvura: Tembiricha yemvura ndechimwe chezvinhu zvakakosha zvinokanganisa HEC hydration nguva. Kazhinji kutaura, tembiricha yepamusoro yemvura inogona kukurumidzira iyo hydration process yeHEC. Semuenzaniso, mumvura inodziya, HEC inonyorovesa nekukurumidza kupfuura mumvura inotonhora. Zvisinei, tembiricha yemvura yakawandisa inogona kuita kuti HEC inyunguduke zvisina kuenzana uye iite masumbu, saka kazhinji inokurudzirwa kudzora tembiricha yemvura iri pakati pe20°C ne40°C.
Kukurudzira kukurumidza uye nzira: Kukurudzira inzira inokosha yekusimudzira HEC hydration. Iyo inokurumidza kukurumidza kukurumidza, iyo ipfupi iyo hydration nguva yeHEC inowanzo. Nekudaro, kuwedzeredza kunogona kuunza mabhuru akawandisa, zvichikanganisa kunaka kwemhinduro. Zvinowanzokurudzirwa kuwedzera HEC hupfu zvishoma nezvishoma nekudzika kwakadzika kubvongodza kudzivirira kuumbwa kweagglomerates uye kuchengetedza zvine mwero kukurudzira mukati meiyo hydration process.
pH kukosha kwemhinduro: HEC inotaridzika kune pH kukosha uye inoita zvakanyanya munzvimbo isina kwayakarerekera kana zvishoma acidic. Pasi peyakanyanya pH mamiriro (akadai seakasimba acids kana mabhesi), solubility yeHEC inogona kukanganiswa, nekudaro kuwedzera nguva ye hydration. Nokudaro, zvinowanzokurudzirwa kuita hydration yeHEC munzvimbo iri pedyo-neutral pH.
Pretreatment nzira dzeHEC: Pretreatment nzira dzakadai sekuomesa, kugaya, nezvimwewo zvichakanganisawo hydration performance yeHEC. Yakanyatsogadziriswa HEC poda inonyungudika uye inonyorovesa nekukurumidza. Semuenzaniso, pre-dispersing HEC powder mu ethanol kana glycerin isati yawedzera kumvura inogona kuderedza zvakanyanya hydration nguva.
Mibvunzo Inowanzo bvunzwa Panguva yeHEC Hydration process
Munguva ye hydration process yeHEC, unogona kusangana nematambudziko akajairika, ayo anowanzo hukama nemaitiro ekushanda kana mamiriro ezvakatipoteredza:
Agglomeration: Pasi pemamiriro asina kunaka ekushanda, HEC poda inogona kuumba agglomerations mumvura. Izvi zvinowanzoitika nekuda kwekuti apo HEC powder inosangana nemvura, jira rekunze rinotora pakarepo mvura uye kuputika, kudzivirira mukati memukati kuti usasangana nemvura, nokudaro kuumba zviputi. Iyi mamiriro anowedzera zvakanyanya nguva ye hydration uye inotungamira kune mhinduro inhomogeneity. Kuti udzivise izvi, zvinowanzokurudzirwa kuti zvishoma nezvishoma kusasa muHEC powder paunenge uchikurudzira.
Dambudziko reBubble: Pasi pesimba rakakura rekugera kana kukurumidza kumhanyisa, HEC mhinduro dzinowanzo kuunza huwandu hukuru hwemabhuru. Aya mabhuru emhepo anogona kukanganisa kunaka kwemhinduro yekupedzisira, kunyanya kana yakashandiswa mumapendi kana zvizorwa. Nokudaro, kubvongodza kwakasimba kunofanira kudziviswa panguva ye hydration process, uye kuumbwa kwemabhuruku kunogona kuderedzwa nekuwedzera defoamers.
Solution viscosity shanduko: Iyo viscosity yeHEC mhinduro zvishoma nezvishoma inowedzera sezvo hydration process inoenderera. Mune mamwe maapplication, akadai sekugadzira machira kana anonamira, kutonga kwe viscosity kwakakosha. Kana nguva ye hydration yakarebesa, viscosity inogona kunge yakanyanyisa, inokanganisa kushanda. Naizvozvo, kunyatso kudzora nguva ye hydration kwakakosha kuti uwane inodiwa mhinduro viscosity.
HEC Hydration mune Inoshanda Zvishandiso
Mumashandisirwo anoshanda, iyo hydration process yeHEC inowanzoda kuvandudzwa pamwe chete nemaitiro chaiwo ekugadzira uye zvigadzirwa zvinodiwa. Semuenzaniso, mukugadzirwa kwezvizoro, kuitira kuti uwane chimiro chinodiwa uye kugadzikana, HEC inowanzofanonyungudutswa mumvura inodziya uye ipapo zvimwe zvinoshandiswa zvinowedzerwa zvishoma nezvishoma. Mumachira ekuvaka, zvingave zvakafanira kugadzirisa kukurumidza kumhanyisa uye tembiricha yemvura kuti ikurumidze hydration maitiro eHEC, nekudaro ichivandudza kugadzirwa kwehunyanzvi.
Iyo hydration nguva yeHEC isimba rinoita uye rinokanganiswa zvakanyanya nezvakawanda zvinhu. Mumamiriro akasiyana-siyana ekushandisa, inoda kugadziriswa uye kugadziriswa maererano nemamiriro ezvinhu chaiwo kuti ave nechokwadi chokuti HEC inogona kunwa mvura nokukurumidza uye yakaenzana uye inogadzira mhinduro yakagadzikana. Izvi hazvingobatsiri kuvandudza kushanda kwekugadzira asiwo zvinovimbisa kunaka uye kuita kwechigadzirwa chekupedzisira.
