Hydroxyethyl cellulose na ethyl cellulose

Hydroxyethyl cellulose na ethyl cellulose ni ibintu bibiri bitandukanye. Bifite imiterere ikurikira.

Hydroxyethyl cellulose

Nk'umuti utari ionic surfactant, uretse gukurura, guhagarika, gufatanya, kuremba, gukora filime, gukwirakwiza, kubika amazi no gutanga colloids zirinda, ifite kandi ibi bikurikira:

1. HEC ishongeshwa mu mazi ashyushye cyangwa akonje, kandi ntigwa iyo ubushyuhe bwinshi cyangwa ishyushye, ku buryo igira imiterere itandukanye yo gushonga no gushonga, kandi idashyuha cyane;

2. Idafite ionic ubwayo ishobora kubana n'izindi polymer nyinshi zishobora gushonga mu mazi, surfactants n'umunyu, kandi ni igikoresho cyiza cyane cyo gukurura colloidal kirimo electrolyte nyinshi;

3. Ubushobozi bwo kubika amazi buri hejuru inshuro ebyiri ugereranyije n’ubwa methyl cellulose, kandi bufite uburyo bwo kugenzura neza amazi;

4. Ugereranyije na selulosi ya methyl izwi na selulosi ya hydroxypropyl methyl, ubushobozi bwo gutatanya bwa HEC ni bwo bubi cyane, ariko koloyide irinda ifite ubushobozi bukomeye cyane.

Selulose ya ethyl

Ni eteri ya cellulose idafite ionic idashonga mu mazi ariko ishonga mu bintu bikomoka ku bimera. Ifite imiterere ikurikira:

1. Ntibyoroshye gutwika.

2. Ubushyuhe buhamye kandi butuma ikirere gishyuha neza.

3. Nta guhinduka kw'ibara ry'izuba.

4. Guhindura imiterere y'umubiri neza.

5. Imiterere myiza ya dielectric.

6. Ifite ubudahangarwa bwiza bwa alkali kandi irwanya aside nke.

7. Imikorere myiza yo kurwanya gusaza.

8. Ubudahangarwa bwiza ku gukurura umunyu, ubukonje n'ubushuhe.

9. Irahamye ku miti, ibikwa igihe kirekire idasenyuka.

10. Ihuye neza n'amaresini menshi kandi ihuye neza n'amapulasitiki yose.

11. Biroroshye guhindura ibara mu gihe hari ahantu hakomeye hafite alkaline n'ubushyuhe bwinshi.
