Iselulosi yeHydroxyethyl (HEC) i-polymer engekho i-ionic emanzini e-soluble esetyenziswa ngokubanzi kwiingubo, izithambiso, izinto zokucoca kunye nezixhobo zokwakha. Ngenxa yokuqina kwayo kakuhle, ukuzinzisa kunye neempawu zokwenza ifilimu, kufuneka ichithwe emanzini ukwenza isisombululo esifanayo xa sisetyenziswa.
1. Ukulungiswa kokuchithwa
Izixhobo ezifunekayo kunye nezixhobo
I-Hydroxyethyl cellulose powder
Amanzi acocekileyo okanye amanzi adibeneyo
Izixhobo zokuxhoma (ezifana neerodi zokuxhokonxa, izivusi zombane)
Izikhongozeli (ezifana neglasi, iiemele zeplastiki)
Ukulumkela
Sebenzisa amanzi acocekileyo okanye amanzi adibeneyo ukuphepha ukungcola okuchaphazela umphumo wokutshatyalaliswa.
I-Hydroxyethyl cellulose ivakalelwa kwiqondo lokushisa, kwaye ubushushu bamanzi bunokulungelelaniswa njengoko kufuneka ngexesha lenkqubo yokuchithwa (amanzi abandayo okanye indlela yamanzi afudumeleyo).
2. Iindlela ezimbini ezisetyenziswa ngokuqhelekileyo zokuchithwa
(1) Indlela yamanzi abandayo
Kancinci ufefe umgubo: Kwisikhongozeli esizaliswe ngamanzi abandayo, kancinane kwaye ngokulinganayo ufefe umgubo we-HEC emanzini ukunqanda ukongeza umgubo omninzi ngexesha elinye ukuze ubangele i-caking.
Ukuvuselela kunye nokusabalalisa: Sebenzisa i-stirrer ukuvuselela ngesantya esiphantsi ukusabalalisa umgubo emanzini ukwenza ukumiswa. I-agglomeration ingenzeka ngeli xesha, kodwa ungakhathazeki.
Ukuma kunye nokumanzisa: Vumela ukusasazeka kume iiyure ze-0.5-2 ukuvumela umgubo ukuba ufunxe ngokupheleleyo amanzi kwaye udumbe.
Qhubeka uvuselela: Gxuma de isisombululo sibonakale ngokupheleleyo okanye singenalo imvakalelo ye-granular, edla ngokuthatha imizuzu engama-20-40.
(2) Indlela yamanzi ashushu (indlela yokusasazwa kwamanzi ashushu)
Ukusasazwa kwangaphambili: Yongeza inani elincinci leI-HECumgubo ukuya kwi-50-60℃ yamanzi ashushu kwaye uvuselele ngokukhawuleza ukuwachithachitha. Qaphela ukunqanda i-powder agglomeration.
Ukuhlanjululwa kwamanzi abandayo: Emva kokuba umgubo usasazwa okokuqala, yongeza amanzi abandayo ukuze uhlambulule kwindawo ekujoliswe kuyo kwaye uvuselele ngexesha elifanayo ukukhawulezisa ukuchithwa.
Ukupholisa nokuma: Lindela isisombululo sokupholisa kwaye ume ixesha elide ukuvumela i-HEC ukuba ichithe ngokupheleleyo.
3. Iindlela eziphambili zokuchithwa
Kuphephe i-agglomeration: Xa ufaka i-HEC, yifefe ngokuthe chu kwaye uqhubeke uvuselela. Ukuba i-agglomerations ifunyenwe, sebenzisa i-seve ukuze usasaze umgubo.
Ukulawulwa kweqondo lokushisa lokuchithwa: Indlela yamanzi abandayo ifanelekile kwizisombululo ezifuna ukugcinwa ixesha elide, kwaye indlela yamanzi afudumele inokunciphisa ixesha lokuchithwa.
Ixesha lokuchithwa: Ingasetyenziselwa xa ukungafihli ngokupheleleyo ukuya kumgangatho, okuhlala kuthatha imizuzu engama-20 ukuya kwiiyure ezininzi, kuxhomekeke kwiinkcukacha kunye nokugxininiswa kwe-HEC.
4. Amanqaku
Ukugxininiswa kwesisombululo: Ngokuqhelekileyo kulawulwa phakathi kwe-0.5% -2%, kwaye ugxininiso oluthile luhlengahlengiswa ngokweemfuno zangempela.
Ukugcinwa kunye nokuzinza: Isisombululo se-HEC kufuneka sigcinwe kwisitya esivaliweyo ukuphepha ukungcoliswa okanye ukuvezwa kweendawo eziphezulu zokushisa ezichaphazela ukuzinza kwayo.
Ngala manyathelo angasentla,i-hydroxyethyl celluloseinokuchithwa ngokufanelekileyo emanzini ukwenza isisombululo esifanayo kunye nesicacileyo, esifanelekileyo kwiimeko ezahlukeneyo zesicelo.
