Zeziphi izinto ezisetyenziswayo kwi-surfactants kwi-coatings?

Ii-surfactantsludidi lweekhompawundi ezinezakhiwo ezizodwa zeemolekyuli ezinokulungelelaniswa kujongano okanye umphezulu, ukuguqula ngokuphawulekayo ukuxinezeleka komphezulu okanye iimpawu zobuso. Kushishino lokugquma, ii-surfactants zidlala indima ebalulekileyo kwizicelo ezahlukeneyo, kubandakanywa i-emulsification, ukumanzisa, ukusasazwa, ukukhupha amagwebu, ukulinganisa, iziphumo ze-antistatic, kunye nokunye, oko kuphucula ukuzinza, ukusebenza kwesicelo, kunye nomgangatho wokugqibela weengubo.

1.Emulsification

Kwiingubo ezisekelwe kwi-emulsion (ezifana neengubo zamanzi), i-emulsifiers ibalulekile. Banciphisa ukuxhatshazwa kwe-interface phakathi kwezigaba zeoli kunye namanzi, okwenza kube lula ukubunjwa kwe-emulsions ezinzile ukusuka kumacandelo angenakulinganiswa. Iziminzi eziqhelekileyo ziquka i-anionic surfactants (umzekelo, i-sodium dodecylbenzene sulfonate) kunye ne-nonionic surfactants (umzekelo, i-polyoxyethylene ethers).

2.Ukumanzisa kwePigment kunye nokusasazwa

Ukusasazwa okufanayo kwee-pigments kwiingubo kuchaphazela ngokuthe ngqo ukukhanya, ukuzinza, kunye nokusebenza kombala. Ii-agent zokumanzisa kunye nezisasazo zinciphisa ukuxinana phakathi kobuso phakathi kwee-pigments kunye nezibophelelo, ukukhuthaza ukumanzisa okufanayo kunye nokusabalalisa okuzinzileyo ngelixa kuthintela i-agglomeration kunye nokuhlalisa.

3. Ukukhupha amagwebu kunye noLawulo lwegwebu

Ngexesha lokuvelisa kunye nokusetyenziswa, iingubo zivame ukuvelisa amaqamza, anokuthi adibanise ukubonakala kwefilimu kunye nokusebenza. I-Defoamers (umzekelo, i-silicone-based okanye i-oyile ye-mineral-based) iphazamisa izakhiwo ze-foam, ukunciphisa ukubunjwa kwe-bubble kunye nokuqinisekisa umgangatho ogudileyo, ongenasiphako.

4. UkuPhuculwa kweNqanaba

Ipropathi yokulinganisa yeengubo inquma ukulula kunye nokubonakala kwefilimu eyomileyo. Iiarhente zomgangatho zisebenza ngeendlela ezimbini eziphambili:

•​ Ukunciphisa ukuxinezeleka komphezulu: Iqinisekisa ukuba isasazeke nakwi substrates, inciphisa iziphene ezifana namaxolo eorenji okanye icratering.

• Ukumodareyitha umphunga wesinyibilikisi: Yandisa ixesha lokuqukuqela, nto leyo evumela ukuba isambatho silingane ngokwaneleyo phambi kokuba sinyange.

5.Ukusebenza kweAntistatic

Kwi-electronics, ukupakishwa, kunye nezinye iindawo, iingubo zinokuthi ziqokelele iintlawulo ezimileyo ngenxa yokukhuhlane, ezibeka umngcipheko wokhuseleko. Ii-Antistatic agents (umzekelo, ii-cationic surfactants) zibhengeza ukufuma kwe-ambient ukwenza umaleko we-conductive kumphezulu wokugquma, ukuququzelela ukuchithwa kwentlawulo kunye nokunciphisa iingozi ze-electrostatic.

6.Ukhuseleko lweAntimicrobial kunye neFungicidal

Kwiindawo ezifumileyo, iingubo zixhomekeke ekukhuleni kwe-microbial, ekhokelela ekuthotyweni kwefilimu. I-Antimicrobial kunye ne-fungicidal agents (umzekelo, i-quaternary ammonium compounds) inqanda ukwanda kwe-microbial, ukwandisa ubomi beshelufu kunye nokuqina kwenkonzo yeengubo.

7.Ukuphuculwa kweglosi kunye nokuPhuculwa kweSlip

Iingubo ezithile zifuna ukukhazimla okuphezulu okanye umphezulu ogudileyo (umzekelo, ifenitshala okanye iingubo zamashishini). Izixhasi zegloss kunye ne-slip additives (umzekelo, i-wax okanye i-silicones) iphucula ukubonakala kwefilimu kunye nokunciphisa ukungqubuzana kwendawo, ukuphucula ukunxiba kunye neempawu ezithintekayo.

Ii-surfactants zisebenza iindima ezininzi kumzi-mveliso wokugquma, ukusuka ekuphuculeni ukusebenza komgangatho ukuya ekuphakamiseni iipropathi zefilimu zokugqibela, zonke ziphakamisa amandla azo olawulo ahlukeneyo. Ngokuqhubela phambili kwe-eco-friendly kunye nokusebenza okuphezulu kokutyatyekwa, inoveli, esebenzayo, kunye nee-surfactants ezinobuthi obuphantsi ziya kuhlala ziyingqwalasela ephambili kuphando lwetekhnoloji yokwaleka kwixesha elizayo.
