Ndeapi mashandisirwo emasurfactants mune coatings?

Surfactantsikirasi yemakomponi ane akasiyana mamorekuru maumbirwo anogona kuenderana pakatarisana kana pamusoro, achichinja zvakanyanya kushushikana kwepasi kana zvimiro zvemeso. Muindasitiri yekupfeka, ma surfactants anoita basa rakakosha mumashandisirwo akasiyana siyana, anosanganisira emulsification, wetting, dispersion, defoaming, leveling, antistatic effects, nezvimwe, zvichiwedzera kugadzikana, kuita kweapplication, uye mhando yekupedzisira yejasi.

1.Emulsification

Mu emulsion-based coatings (yakadai semvura yakasvibiswa), emulsifiers inokosha. Vanoderedza kusawirirana kwepakati pakati pezvikamu zvemafuta nemvura, zvichiita kuti pave nekugadzikana kwema emulsions kubva kune immiscible components. Maemulsifiers akajairika anosanganisira anionic surfactants (semuenzaniso, sodium dodecylbenzene sulfonate) uye nonionic surfactants (semuenzaniso, polyoxyethylene ethers).

2.Pigment Kunyorova uye Kupararira

Iyo yunifomu yekuparadzira pigment mumajasi inokanganisa zvakananga opacity, kugadzikana, uye kuita kwemavara. Kunyorova uye kuparadzira vamiririri kunoderedza kusawirirana kwechiso pakati pe pigment uye mabhaidha, kusimudzira kunyorova kweyunifomu uye kupararira kwakagadzikana uku ichidzivirira kuungana uye kugadzirisa.

3.Defoaming uye Foam Control

Munguva yekugadzira uye kushandisa, machira anowanzo gadzira mabhuru, ayo anogona kukanganisa kutaridzika kwefirimu uye kuita. Defoamers (semuenzaniso, silicone-based kana mineral oil-based) inokanganisa zvimiro zvefuro, kuderedza kuumbwa kwebubble uye kuve nechokwadi chepamusoro, isina kukanganisa.

4.Leveling Improvement

Iyo yekuenzanisa pfuma yejasi inogadzirisa kutsvedzerera uye kutaridzika kweiyo firimu yakaomeswa. Leveling vamiririri vanoshanda kuburikidza nenzira mbiri dzekutanga:

•​ Kuderedza kushushikana kwepasi: Inopa shuwa kupararira pamasubstrates, kuderedza kuremara seganda reorenji kana cratering.

• ​Modulating solvent evaporation: Inowedzera nguva yekuyerera, ichibvumira kuvharidzira kuti kuenzane zvakakwana kusati kwapora.

5.Antistatic Functionality

Mune zvemagetsi, kurongedza, uye mamwe minda, machira anogona kuunganidza static machaji nekuda kwekukweshana, zvichiunza njodzi yekuchengetedza. Antistatic agents (semuenzaniso, cationic surfactants) adsorb ambient mwando kuti iite conductive layer pamusoro pekuputira, kufambisa kushaja uye kuderedza njodzi dzemagetsi.

6.Antimicrobial uye Fungicidal Dziviriro

Munzvimbo dzine hunyoro, mabhanhire anowanzoita kukura kwehutachiona, zvichiita kuti firimu riparare. Antimicrobial uye fungicidal agents (semuenzaniso, quaternary ammonium compounds) inhibisa kuwanda kwehutachiona, kuwedzera hupenyu hwesherufu uye kusimba kwesevhisi yejasi.

7.Gloss Enhancement uye Slip Improvement

Mamwe machira anoda kupenya kwepamusoro kana nzvimbo dzakatsetseka (semuenzaniso, fenicha kana maindasitiri emachira). Gloss enhancers uye slip additives (semuenzaniso, waxes kana silicones) inovandudza kutaridzika kwefirimu uye kuderedza kukweshera kwepasi, inosimudzira kupfeka kuramba uye tactile zvimiro.

Masurfactants anoshanda akawanda muindastiri yekupfeka, kubva pakugadzirisa mashandiro ekugadzirisa kusvika pakukwidziridza ekupedzisira firimu zvimiro, zvese zvichisimudzira kugona kwavo kwakasiyana kwemaitiro ekutonga. Nekusimudzira kwe eco-inoshamwaridzika uye yepamusoro-inoshanda coatings, inoveli, inoshanda, uye yakaderera-chepfu surfactants icharamba iri yakakosha kutarisisa mune ramangwana coatings tekinoroji yekutsvaga.
