Hydroxyethyl Cellulose (HEC) ke polima e qhibilihang ka metsing e se nang ionic e sebelisoang haholo ho koahela, litlolo, litlolo le thepa ea mohaho. Ka lebaka la ho teteka ha eona hantle, ho tsitsisa le ho etsa lifilimi, e hloka ho qhibiliha ka metsing ho etsa tharollo e ts'oanang ha e sebelisoa.
1. Tokisetso ea ho qhalana
Lisebelisoa le lisebelisoa tse hlokahalang
Hydroxyethyl cellulose phofo
Metsi a hloekileng kapa metsi a hloekisitsoeng
Lisebelisoa tse hlohlelletsang (tse kang lithupa, li-stirrers tsa motlakase)
Lijana (tse kang likhalase, linkho tsa polasetiki)
Mehato ya tlhokomelo
Sebelisa metsi a hloekileng kapa metsi a hloekisitsoeng ho qoba litšila tse amang phello ea ho qhibiliha.
Hydroxyethyl cellulose e na le maikutlo a mocheso, 'me mocheso oa metsi o ka fetoloa kamoo ho hlokahalang nakong ea ho qhibiliha (metsi a batang kapa mokhoa oa metsi a futhumetseng).
2. Mekhoa e 'meli e sebelisoang hangata ea ho qhala
(1) Mokhoa oa metsi a batang
Ha butle-butle u fafatse phofo: Ka sejaneng se tletseng metsi a batang, butle-butle le ka ho lekana tšela phofo ea HEC metsing ho qoba ho tšela phofo e ngata ka nako e le 'ngoe ho baka caking.
Ho hlohlelletsa le ho qhalakanya: Sebelisa sehlaseli ho sisinya ka lebelo le tlase ho qhala phofo ka metsing ho etsa ho emisa. Agglomeration e ka etsahala ka nako ena, empa u se ke oa tšoenyeha.
Ho ema le ho koloba: Tlohela ho hasana ho eme lihora tse 0.5-2 ho lumella phofo ho monya metsi ka ho feletseng le ho ruruha.
Tsoela pele ho susumetsa: Hlohlelletsa ho fihlela tharollo e hlakile ka ho feletseng kapa e se na maikutlo a granular, ao hangata a nkang metsotso e 20-40.
(2) Mokhoa oa metsi a futhumetseng (metsi a chesang pele a hasana)
Phallo pele: Eketsa palo e nyane eaHECphofo ho 50-60 ℃ metsi a chesang 'me u tsose ka potlako ho e hasanya. Ela hloko ho qoba ho kopana ha phofo.
Ho hlapolla ha metsi a batang: Ka mor'a hore phofo e qale ho qhalakanngoa, eketsa metsi a batang ho hlapolla sebakeng seo u se batlang ebe u hlohlelletsa ka nako e le 'ngoe ho potlakisa ho qhibiliha.
Ho pholile le ho ema: Emela hore tharollo e pholile 'me u eme nako e telele ho lumella HEC ho qhibiliha ka ho feletseng.
3. Mekhoa ea bohlokoa ea ho qhala
Qoba agglomeration: Ha u eketsa HEC, e fafatse butle 'me u lule u hlohlelletsa. Haeba li-agglomerations li fumanoa, sebelisa sieve ho qhala phofo.
Taolo ea mocheso oa ho qhibiliha: Mokhoa oa metsi a batang o loketse litharollo tse lokelang ho bolokoa nako e telele, 'me mokhoa oa metsi a futhumetseng o ka khutsufatsa nako ea ho qhibiliha.
Nako ea ho qhibiliha: E ka sebelisoa ha ho pepeseha ho feletseng ho fihlela maemo a tloaelehileng, ao hangata a nkang metsotso ea 20 ho lihora tse 'maloa, ho itšetlehile ka litlhaloso le mahloriso a HEC.
4. Lintlha
Tlhokomelo ea tharollo: Ka kakaretso e laoloa pakeng tsa 0.5% -2%, 'me mahloriso a khethehileng a lokisoa ho latela litlhoko tsa sebele.
Ho boloka le botsitso: Tharollo ea HEC e lokela ho bolokoa ka sejaneng se tiisitsoeng ho qoba tšilafalo kapa ho pepesehela maemo a mocheso a phahameng a amang botsitso ba eona.
Ka mehato e ka holimo,hydroxyethyl cellulosee ka qhibiliha ka katleho metsing ho etsa tharollo e ts'oanang le e hlakileng, e loketseng maemo a fapaneng a kopo.
