I-HEC (HydroxYethyl celtuleose) i-polymer engenawo amanzi e-ionic asetshenziswa kabanzi ekuhlotsheni, izinto zokwakha, imikhiqizo yokunakekelwa komuntu siqu, imikhiqizo yezemithi kanye nezinye izimboni. Isetshenziswa kakhulu njengomuntu omkhulu, osomisa umenzeli we-ejenti, i-binder kanye ne-ejenti eyakha amafilimu, enamanzi amahle e-solubity kanye nekhono lokuqina.
1. Ukukhetha nokulungiswa kwe-HEC
Ukukhetha umkhiqizo we-HEC ofanele yisinyathelo sokuqala esisebenzayo. I-HEC inezinsimbi ezihlukile zamangqamuzana, i-solubity kanye nekhono lokuqina lizohluka. Ngakho-ke, izinhlobonhlobo ze-HEC ezifanele kufanele zikhethwe ngokuya ngezidingo ezithile zohlelo lokusebenza. Isibonelo, lapho kusetshenziswa e-Coatings, i-HEC enokubonakala okulinganiselayo kudinga ukukhethwa; Ngesikhathi emikhiqizweni yokunakekelwa komuntu siqu, i-HEC enokugcinwa komswakama okuphezulu kanye nokuqina kwe-biocomlity kungadinga ukukhethwa.
Ngaphambi kokusebenzisa, i-HEC imvamisa ikhona ngefomu le-powder, futhi ukunakekelwa kufanele kuthathwe ukuvikela ukumunca umswakama kanye nokuqalwa kwe-agglomeration lapho kusetshenziswa. I-HEC ingagcinwa endaweni eyomile, enomoya omuhle ukugwema ukuvezwa okuqondile emoyeni onomswakama.
2. Inqubo yokuqothula ye-HEC
I-HEC iyi-polymer esolulekayo yamanzi engachithwa ngokuqondile emanzini abandayo noma ashisayo. Nazi izinyathelo ezijwayelekile zokuqeda i-HEC:
I-Dispering HEC: Yengeza kancane i-hecc powder kumanzi avusiwe ukugwema i-agglomeration. Ukuvimbela i-HEC ekutholeni indawo emanzini, amanzi angafudunyezwa ku-60-70 ℃ ngaphambi kokufafaza kancane kancane i-hec powder emanzini.
Inqubo yokuqothula: I-HEC inciphisa kancane emanzini futhi imvamisa idinga ukushukumisa imizuzu engama-30 kuye kumahora ama-2, ngokuya ngesisindo se-hec. Ngesikhathi senqubo yokuvutha, izinga lokushisa lamanzi lingakhuphuka ngokufanele ukusheshisa ukuchithwa, kepha ngokuvamile hhayi ngaphezu kwe-90 ℃.
Ukulungisa i-PH: I-HEC iyazwela izinguquko ku-pH. Kwezinye izinhlelo zokusebenza, i-PH yesisombululo ingahle idinge ukushintshwa ebangeni elithile (ngokuvamile 6-8) ukufeza umphumela omuhle kakhulu nokuqina.
Ukuma nokuvuthwa: Isixazululo se-hec esincibilikisiwe sivame ukumelana namahora ambalwa ukuze ubusuku bonke ukuze uvuthwe ngokugcwele. Lokhu kusiza ukuthuthukisa ukuqina kwengxenye yesisombululo futhi kuqinisekiswe ukuvumelana komphumela wokuqina.
3. Ukusetshenziswa kwe-HEC
Umphumela wokuqina we-HEC usetshenziswa kabanzi emikhiqizweni ehlukahlukene. Lokhu okulandelayo kunezimo ezimbalwa zesicelo ezijwayelekile nezindlela zazo zokusebenzisa:
Isicelo in Coatings:
I-HEC, njengesikhulu sokumbona, ingathuthukisa uketshezi nokuhlanza izimbozo futhi ivikele ukumboza kusuka ekuchitheni.
Uma usebenzisa, engeza isisombululo se-hec ngqo kwinhlanganisela futhi uvuse ngokulinganayo. Naka ukulawula inani le-HEC elingezwe, elivame uku-0,1% kuya ku-0.5% yenani eliphelele lokuhlanganisa.
Ukugwema ukubonakala kwe-coating kuncipha ngaphansi kwe-shear ephezulu, khetha i-HEC ngesisindo esifanelekile se-molecular nokubonakala.
Isicelo emikhiqizweni yokunakekelwa komuntu siqu:
Emikhiqizweni enjenge-shampoo ne-gel ye-gel, i-HEC ingasetshenziswa njenge-smighter kanye ne-stabilizer ukunikeza umkhiqizo omuhle wokuthinta nokuthambisa.
Lapho usebenzisa, i-HEC ingachithwa esigabeni samanzi somkhiqizo, futhi unake ukuvuselela ngokulinganayo ukugwema ukwakheka kokuhlangana.
Inani elifanelekile lokungezwa livame phakathi kuka-0.5% no-2%, futhi liyalungiswa ngokuya ngomphumela wokuqina oyifunayo.
Isicelo ezintweni zokwakha:
I-HEC isetshenziswa kakhulu ngodaka, i-gypsum, njll. Ezintweni zokwakha, ezingathuthukisa ukugcinwa kwamanzi kanye nokusebenza kokusebenza kwezinto ezibonakalayo.
Lapho isetshenziswa, i-HEC ingachithwa emanzini kuqala, bese ikhambi lingezwa kwingxube yezinto zokwakha.
Inani lokungezwa lincike kokuqukethwe okuthile, imvamisa phakathi kuka-0,1% no-0.3%.
4. Izinyathelo zokusebenzisa ukusetshenziswa
Ukulawulwa kokushisa ngesikhathi sokuchithwa: Yize ukukhulisa izinga lokushisa kungasheshisa ukuchithwa kwe-hec, izinga lokushisa kakhulu lingadala ukonakala kwe-HEC, ngakho-ke gwema izinga lokushisa eliphakeme kakhulu.
Ijubane elishukumisayo nesikhathi: Ngokushesha kakhulu isivinini esishukumisayo singadala izinkinga ze-Foaming futhi zithinte ikhwalithi yomkhiqizo wokugcina. Cabanga ukusebenzisa i-degasser ukususa ama-bubble kwikhambi.
Ukuvumelana nezinye izithako: Uma ungeza i-HEC kwifomula, unake ukuhambisana kwawo nezinye izithako. Ezinye izithako zingathinta umphumela wokuqina noma i-solubility ye-hec, njengokugxila okuphezulu kwama-electrolyte.
Isitoreji nokuqina: Isixazululo se-HEC kufanele sisetshenziswe ngokushesha okukhulu, ngoba isitoreji sesikhathi eside singathinta ukubonwa nokuqina kwesisombululo.
I-Hec Shidener isetshenziswa kabanzi emikhakheni ehlukahlukene ngokusebenza kwayo okuhle. Indlela yokusebenzisa efanelekile nezinyathelo zokusebenza kungaqinisekisa ukuthi i-HEC idlala umphumela omuhle kakhulu. Ngesikhathi sokusebenzisa, ukunaka izinto ezinjengendlela yokuchithwa, ukulawulwa kokushisa, inani lokungezelela, kanye nokuhambisana nezinye izithako kungasiza ukufeza umphumela onzima wokuqina kanye nokusebenza komkhiqizo.
