Ni ubuhe buryo bukoreshwa bwa surfactants muri coatings?

Surfactantsni urwego rwibintu bifite molekulire idasanzwe ishobora guhuza intera cyangwa isura, ihindura cyane uburemere bwimiterere cyangwa imiterere yimiterere. Mu nganda zitwikiriye, surfactants zigira uruhare runini mubikorwa bitandukanye, birimo emulisile, gutose, gutatanya, gusebanya, kuringaniza, ingaruka za antistatike, nibindi byinshi, bityo bikazamura ituze, imikorere, hamwe nubwiza bwanyuma.

1.Kwiyerekana

Muri emulsiyo ishingiye kuri emuliyoni (nk'amazi yo mu mazi), emulisiferi ni ngombwa. Bagabanya impagarara hagati yamavuta nicyiciro cyamazi, bigafasha gukora emulisiyo zihamye ziva mubintu bitagaragara. Emulisiferi zisanzwe zirimo anionic surfactants (urugero, sodium dodecylbenzene sulfonate) hamwe na surfactants zidasanzwe (urugero, polixyethylene ethers).

2.Petment Wetting and Dispersion

Ikwirakwizwa rimwe rya pigment mu mwenda bigira ingaruka ku buryo butaziguye, guhagarara, no gukora amabara. Kuvomera no gukwirakwiza ibintu bigabanya impagarara hagati yimiterere ya pigment na binders, bigatera guhindagurika hamwe no gutatana bihamye mugihe birinda guhuriza hamwe no gutura.

3.Kugenzura no kugenzura ifuro

Mugihe cyo gukora no kubishyira mu bikorwa, impuzu zikunda kubyara ibintu byinshi, bishobora guhungabanya isura ya firime n'imikorere. Defoamers (urugero, ishingiye kuri silicone cyangwa minerval ishingiye ku mavuta) ihungabanya imiterere ya furo, igabanya ibibyimba kandi ikanareba neza neza.

4.Gutezimbere

Kuringaniza imitungo igereranya neza no kugaragara kwa firime yumye. Kuringaniza abakozi bikora binyuze muburyo bubiri bwibanze:

• Kugabanya impagarara zubuso: Iremeza no gukwirakwira kuri substrate, kugabanya inenge nkibishishwa bya orange cyangwa igikona.

• Guhindura imyuka yumuti: Yongerera igihe cyo gutembera, kwemerera igipfundikizo kuringaniza bihagije mbere yo gukira.

5.Imikorere idahwitse

Muri elegitoroniki, gupakira, hamwe nizindi nzego, impuzu zishobora kwegeranya amafaranga ahamye kubera guterana amagambo, bikaba byangiza umutekano. Imiti igabanya ubukana (urugero, cactic surfactants) adsorb yubushyuhe bwibidukikije kugirango ikore urwego rwimikorere hejuru yikibiriti, byorohereza ikwirakwizwa ryamafaranga no kugabanya ingaruka ziterwa na electrostatike.

6. Kurinda mikorobe na Fungicidal Kurinda

Mu bidukikije bitose, impuzu zikunda gukura kwa mikorobe, biganisha kuri firime. Imiti igabanya ubukana na fungiside (urugero, ibice bya amonium ya quaternary) ibuza ikwirakwizwa rya mikorobe, ikongerera igihe cyo kuramba no kumara igihe kirekire.

7.Gutezimbere Urumuri no Gutezimbere

Ibifuniko bimwe bisaba uburabyo burebure cyangwa hejuru (urugero, ibikoresho byo mu nzu cyangwa inganda). Kongera ububengerane hamwe ninyongeramusaruro (urugero, ibishashara cyangwa silikoni) bizamura firime kandi bigabanye ubushyamirane bwubuso, byongera imbaraga zo kwambara no kwifata neza.

Surfactants ikora imirimo myinshi mubikorwa byo gutwikira, kuva muburyo bwo gutunganya imikorere kugeza kuzamura imitungo ya nyuma ya firime, byose bikoresha ubushobozi bwihariye bwo kugenzura imiterere. Hamwe niterambere ryibidukikije byangiza ibidukikije kandi bikora cyane, ibishya, bikora neza, kandi bifite ubumara buke bizakomeza kwibandwaho mubushakashatsi bwikoranabuhanga rya tekinoroji.
