HEC yo gusiga irangi

Hydroxyethyl selulose (HEC) ninyongera ikoreshwa cyane mubikorwa byo gusiga amarangi, ihabwa agaciro kumiterere yayo itandukanye igira uruhare mugushinga, kuyishyira mubikorwa, no gukora ubwoko butandukanye bwamabara. Dore incamake ya porogaramu, imikorere, hamwe nibitekerezo bya HEC murwego rwo gushushanya amarangi:

1. Intangiriro kuri Hydroxyethyl Cellulose (HEC) mumabara

1.1 Ibisobanuro n'inkomoko

Hydroxyethyl selulose ni polymer-amazi-elegitoronike ikomoka kuri selile ikoresheje reaction ya okiside ya Ethylene. Ubusanzwe ikomoka mubiti cyangwa ipamba kandi igatunganywa kugirango ikore polymer ifite ibintu bitandukanye byerekana amashusho.

1.2 Uruhare mugushushanya

Mu gusiga amarangi, HEC ikora intego nyinshi, zirimo kuzuza irangi, kunoza imiterere, gutanga ituze, no kuzamura muri rusange imikorere n'imikorere.

2. Imikorere ya Hydroxyethyl Cellulose mumabara

2.1 Guhindura imvugo na Thickener

HEC ikora nka rheologiya ihindura kandi ikabyimbye mugushushanya amarangi. Igenzura ubwiza bwirangi, ikabuza gutuza pigment, kandi ikemeza ko irangi rifite aho rihurira nogukoresha byoroshye.

2.2

Nka stabilisateur, HEC ifasha kugumya gutezimbere irangi, kurinda gutandukanya ibyiciro no gukomeza ubutinganyi mugihe cyo kubika.

2.3 Kubika Amazi

HEC yongerera amazi kubika irangi, ikarinda gukama vuba. Ibi bifite agaciro cyane mumarangi ashingiye kumazi, bituma habaho gukora neza no kugabanya ibibazo nkibimenyetso.

2.4 Ibyiza byo gukora firime

HEC igira uruhare mu gushiraho firime ikomeza kandi imwe ku buso busize irangi. Iyi firime itanga igihe kirekire, yongerera imbaraga, kandi inoza isura rusange yubuso busize irangi.

3. Gushyira amarangi

3.1 Irangi rya Latex

HEC isanzwe ikoreshwa mumarangi ya latx cyangwa ashingiye kumazi kugirango igenzure ubwiza, itezimbere irangi, kandi itezimbere imikorere yayo mugihe cyo kuyikoresha no kuyumisha.

3.2 Amabara

Irangi rya emulsiyo, rigizwe nuduce duto twa pigment yatatanye mumazi, HEC ikora nka stabilisateur kandi ikabyimba, ikabuza gutura no gutanga ihame ryifuzwa.

3.3

HEC ikoreshwa mubitambaro byanditse kugirango itezimbere kandi ihamye yibikoresho. Ifasha kurema imyenda imwe kandi ishimishije hejuru irangi.

3.4 Abashitsi n'abacuruzi

Muri primers na kashe, HEC igira uruhare muguhindura imiterere, kugenzura ubukonje, hamwe no gukora firime, bigatuma hategurwa neza substrate.

4. Ibitekerezo no kwirinda

4.1 Guhuza

HEC igomba guhuzwa nibindi bikoresho byo gusiga irangi kugirango wirinde ibibazo nko kugabanya imikorere, flocculation, cyangwa impinduka muburyo bw'irangi.

4.2 Kwibanda

Ubwinshi bwa HEC muburyo bwo gusiga irangi bugomba kugenzurwa neza kugirango ugere kumiterere yifuzwa itagize ingaruka mbi mubindi bice.

4.3 pH Ibyiyumvo

Mugihe muri rusange HEC ihagaze neza mugice kinini cya pH, ni ngombwa gusuzuma pH yo gushushanya irangi kugirango tumenye neza imikorere.

5. Umwanzuro

Hydroxyethyl selulose ninyongera yingirakamaro mubikorwa byo gusiga amarangi, bigira uruhare mugushinga, gutuza, no gukoresha ubwoko butandukanye bwamabara. Imikorere yayo itandukanye ituma ibera amarangi ashingiye kumazi, amarangi ya emulsiyo, hamwe nudusanduku twanditse, nibindi. Abashinzwe gutegura bakeneye gusuzuma neza guhuza, kwibanda, hamwe na pH kugirango barebe ko HEC yunguka byinshi muburyo butandukanye bwo gusiga amarangi.
