Mu kwisiga, hari ibintu byinshi bitagira ibara kandi bidafite impumuro nziza, ariko ibintu bike bidafite uburozi. Uyu munsi ndakumenyeshahydroxyethyl selile, ikunze kugaragara cyane kwisiga cyangwa ibikenerwa bya buri munsi.
Hydroxyethyl Cellulose
Azwi kandi nka (HEC) ni umuhondo wera cyangwa urumuri rwumuhondo, impumuro nziza, fibrous idafite uburozi cyangwa ifu ikomeye. Kubera ibyiza byayo byo kubyimba, guhagarika, gutatanya, kwigana, gukurikiza, gukora firime, kurinda ubushuhe no gutanga imiti ikingira, HEC yakoreshejwe cyane mubuvuzi no kwisiga.
Ibiranga ibicuruzwa
1.
2. Ntabwo ari ionic kandi irashobora kubana nizindi polymers zishonga mumazi, surfactants hamwe numunyu murwego runini. Nibyiza cyane bya colloidal kubyibisubizo birimo dielectrics yibanda cyane;
3. Ubushobozi bwo gufata amazi bukubye kabiri ubwa methyl selulose, kandi bufite uburyo bwiza bwo gutembera neza;
4. Ugereranije na methyl selulose izwi na hydroxypropyl methyl selulose, ubushobozi bwo gukwirakwiza HEC nububi, ariko ubushobozi bwo gukingira colloid nabwo bukomeye.
Roleya HECkwisiga
Uburemere bwa molekuline mu kwisiga, ubwinshi bwibintu nka sintetike karemano na sintetike yubukorikori biratandukanye, birakenewe rero kongeramo solubilizer kugirango ibintu byose bikore neza. Ibishobora gukomera hamwe nubwiza bwa hydroxyethyl selulose bigira uruhare runini, kandi bikagumana imiterere iringaniye, kugirango ibashe kugumana imiterere yumwimerere yo kwisiga mugihe cyigihe cyo guhinduranya ubukonje nubushyuhe. Byongeye kandi, ifite imiterere yubushuhe kandi ikunze kuboneka mumavuta yo kwisiga kubicuruzwa bitanga amazi. Cyane cyane masike, tonier, nibindi hafi ya byose byongeyeho.
ImikorereIngaruka
Hydroxyethyl selulose ikoreshwa mumavuta yo kwisiga nka emollients, umubyimba, nibindi ahanini ntabwo ari uburozi. Kandi ifatwa nkibicuruzwa bya mbere byumutekano wibidukikije na EWG.
