Mene ne amfani da surfactants a cikin shafa?

Masu surfactantswani nau'i ne na mahaɗan da ke da tsarin ƙwayoyin halitta na musamman waɗanda za su iya daidaitawa a mahaɗa ko saman, suna canza yanayin tashin hankali ko halayen haɗin fuska sosai. A cikin masana'antar rufewa, masu surfactants suna taka muhimmiyar rawa a aikace-aikace daban-daban, gami da emulsification, jika, watsawa, defoaming, leveling, antistatic effects, da ƙari, ta haka suna haɓaka kwanciyar hankali, aikin aikace-aikace, da ingancin ƙarshe na rufewa.

1. Emulsification

A cikin shafa mai da aka yi da emulsion (kamar suttura ta ruwa), emulsifiers suna da mahimmanci. Suna rage tashin hankali tsakanin mai da ruwa, wanda ke ba da damar samar da emulsions masu karko daga abubuwan da ba za a iya miscible ba. Emulsifiers na yau da kullun sun haɗa da anionic surfactants (misali, sodium dodecylbenzene sulfonate) da nonionic surfactants (misali, polyoxyethylene ethers).

2. Jikewa da Watsawa na Pigment

Yaɗuwar launuka iri ɗaya a cikin shafa kai tsaye yana shafar rashin haske, kwanciyar hankali, da aikin launi. Abubuwan jika da warwatsewa suna rage tashin hankali tsakanin launuka da abubuwan ɗaurewa, suna haɓaka jika iri ɗaya da warwatse mai karko yayin da suke hana haɗuwa da daidaitawa.

3. Kumfa da kuma Kula da Kumfa

A lokacin samarwa da amfani, shafa mai kan haifar da kumfa, wanda zai iya kawo cikas ga bayyanar fim da aikinsa. Masu cire kumfa (misali, masu amfani da silicone ko masu amfani da man ma'adinai) suna lalata tsarin kumfa, suna rage samuwar kumfa da kuma tabbatar da cewa saman shafi mai santsi, ba shi da lahani.

4. Inganta daidaito

Siffar daidaita shafi tana ƙayyade santsi da bayyanar busasshen fim ɗin. Masu daidaita shafi suna aiki ta hanyoyi guda biyu:

• Rage tashin hankali a saman ƙasa: Yana tabbatar da ko da yaduwa a kan saman ƙasa, yana rage lahani kamar bawon lemu ko kuma fashewar ƙasa.

• Daidaita ƙafewar ruwan da ke narkewa: Yana tsawaita lokacin kwarara, yana barin murfin ya daidaita yadda ya kamata kafin ya warke.

5. Ayyukan Antistatic

A fannin lantarki, marufi, da sauran fannoni, marufi na iya tara caji mai tsauri saboda gogayya, wanda hakan ke haifar da haɗarin aminci. Magungunan hana hana shiga yanayi (misali, cationic surfactants) suna shaƙar danshi na yanayi don samar da wani Layer mai aiki a saman marufi, wanda ke sauƙaƙa watsar da caji da rage haɗarin lantarki.

6. Kariyar kashe ƙwayoyin cuta da ƙwayoyin cuta

A cikin yanayi mai danshi, rufin yana da saurin girma ga ƙwayoyin cuta, wanda ke haifar da lalacewar fim. Magungunan kashe ƙwayoyin cuta da na fungi (misali, mahaɗan ammonium na quaternary) suna hana yaduwar ƙwayoyin cuta, suna tsawaita lokacin da aka ajiye da kuma dorewar aikin rufin.

7. Inganta Haske da Inganta Zamewa

Wasu shafa suna buƙatar saman mai sheƙi ko santsi mai yawa (misali, kayan daki ko fenti na masana'antu). Masu ƙara sheƙi da ƙarin zamewa (misali, kakin zuma ko silicone) suna inganta hasken fim kuma suna rage gogayya a saman, suna ƙara juriya ga lalacewa da halayen taɓawa.

Surfactants suna aiki da ayyuka da yawa a masana'antar rufe fuska, tun daga inganta aikin sarrafawa zuwa haɓaka halayen fim na ƙarshe, duk suna amfani da ƙwarewarsu ta musamman ta daidaita fuska. Tare da ci gaban murfin da ke da kyau ga muhalli da aiki mai girma, sabbin surfactants masu inganci, da ƙarancin guba za su ci gaba da zama babban abin da za a mayar da hankali a kai a binciken fasahar rufe fuska na gaba.
