Surfactantswani nau'in mahadi ne da ke da sifofin kwayoyin halitta na musamman waɗanda za su iya daidaitawa a musaya ko filaye, suna canza tashin hankali sosai ko kaddarorin fuska. A cikin coatings masana'antu, surfactants taka muhimmiyar rawa a daban-daban aikace-aikace, ciki har da emulsification, wetting, watsawa, defoaming, leveling, antistatic effects, kuma mafi, game da shi inganta kwanciyar hankali, aikace-aikace yi, da kuma karshe ingancin coatings.
1. Emulsification
A cikin abubuwan da aka yi amfani da su na emulsion (kamar suttura na ruwa), emulsifiers suna da mahimmanci. Sun rage interfacial tashin hankali tsakanin mai da ruwa bulan, kunna samuwar barga emulsions daga immiscible aka gyara. Abubuwan emulsifiers na gama-gari sun haɗa da surfactants anionic (misali, sodium dodecylbenzene sulfonate) da abubuwan da ba su da tushe (misali, polyoxyethylene ethers).
2.Pigment jike da watsewa
Watsawa iri ɗaya na pigments a cikin sutura kai tsaye yana shafar rashin ƙarfi, kwanciyar hankali, da aikin launi. Jika da tarwatsa jamiái rage interfacial tashin hankali tsakanin pigments da binders, inganta uniform wetting da barga watsawa yayin hana agglomeration da daidaitawa.
3.Defoaming da Kumfa Control
A lokacin samarwa da aikace-aikace, sutura suna haifar da kumfa, wanda zai iya lalata bayyanar fim da aikin. Defoamers (misali, tushen silicone ko tushen mai na ma'adinai) suna lalata tsarin kumfa, rage girman kumfa da tabbatar da santsi, saman rufi mara lahani.
4. Inganta Haɓakawa
Abubuwan da aka daidaita na sutura suna ƙayyade santsi da bayyanar busassun fim. Ma'aikatan haɓaka suna aiki ta hanyoyi biyu na farko:
• Rage tashin hankali: Yana tabbatar da ko da yaɗuwa a kan ma'auni, rage lahani kamar bawo orange ko cratering.
• Modulating ƙauye evaporation: Yana ƙara lokacin kwarara, kyale shafi zuwa matakin daidai kafin warkewa.
5.Ayyukan Antistatic
A cikin na'urorin lantarki, marufi, da sauran filayen, suturar na iya tara cajin da ba ta dace ba saboda gogayya, haifar da haɗarin aminci. Antistatic jamiái (misali, cationic surfactants) adsorb na yanayi danshi ya samar da conductive Layer a kan shafi surface, sauƙaƙe cajin watsawa da kuma rage electrostatic hatsarori.
6.Antimicrobial da Fungicidal Kariya
A cikin yanayi mai laushi, sutura suna da haɗari ga ci gaban ƙananan ƙwayoyin cuta, wanda ke haifar da lalata fim. Magungunan rigakafin ƙwayoyin cuta da fungicidal (misali, mahaɗan ammonium quaternary) suna hana haɓakar ƙwayoyin cuta, haɓaka rayuwar shiryayye da ƙarfin sabis na sutura.
7.Gloss Enhancement and Slip Improvement
Wasu sutura suna buƙatar babban mai sheki ko santsi (misali, kayan daki ko kayan masana'antu). Masu haɓakawa mai sheki da abubuwan da ke zamewa (misali, waxes ko silicones) suna haɓaka kyamar fim da rage juriya, haɓaka juriya da kaddarorin taɓawa.
Surfactants suna yin ayyuka da yawa a cikin masana'antar sutura, daga haɓaka aikin sarrafawa zuwa haɓaka kaddarorin fina-finai na ƙarshe, duk suna ba da damar ƙa'idodin ƙa'idodin tsaka-tsakin su na musamman. Tare da haɓakar haɓakar yanayin yanayi da babban aiki mai ƙarfi, labari, inganci, da ƙarancin haɗari masu haɗari za su kasance babban abin da ake mai da hankali a cikin binciken fasaha na kayan shafa na gaba.
