Kedu ihe bụ ngwa nke surfactants na mkpuchi?

Surfactantsbụ klaasị nke ogige nwere ihe arụrụ arụ molekụla pụrụ iche nke nwere ike ịkwado n'akụkụ ihu ma ọ bụ n'elu, na-agbanwe nke ukwuu esemokwu elu ma ọ bụ njirimara ihu. N'ime ụlọ ọrụ mkpuchi, surfactants na-arụ ọrụ dị mkpa na ngwa dị iche iche, gụnyere emulsification, wetting, disspersion, defoaming, leveling, antistatic mmetụta, na ndị ọzọ, si otú ahụ na-eme ka nkwụsi ike, ngwa ngwa, na ikpeazụ mma mkpuchi.

1.Emulsification

Na mkpuchi nke emulsion (dị ka mkpuchi mmiri), emulsifiers dị mkpa. Ha na-ebelata esemokwu interfacial n'etiti mmanụ na mmiri n'ụzọ, na-enyere guzobe nke anụ emulsions si immiscible components. Ihe emulsifiers ndị a na-ahụkarị gụnyere anionic surfactants (dịka, sodium dodecylbenzene sulfonate) na ihe ndị na-adịghị ahụ anya (dịka ọmụmaatụ, polyoxyethylene ethers).

2.Pigment Wetting na Dispersion

Mgbasa otu nke pigmenti na mkpuchi na-emetụta kpọmkwem opacity, nkwụsi ike, na ịrụ ọrụ agba. Ihe ndị na-eme ka mmiri na-agbasasị na-ebelata esemokwu ihu n'etiti pigments na ndị na-ekekọta ihe, na-akwalite wetting otu na nkesa kwụsiri ike ma na-egbochi agglomeration na idozi.

3. Defoaming na Foam Control

N'oge mmepụta na ngwa ngwa, mkpuchi na-emekarị ka ọ pụta ìhè, nke nwere ike imebi ọdịdị ihe nkiri na arụmọrụ. Defoamers (dịka ọmụmaatụ, silicone ma ọ bụ mmanụ sitere na ịnweta) na-emebi ihe owuwu ụfụfụ, na-ebelata nguzobe afụ ma hụ na elu mkpuchi enweghị ntụpọ.

4.Leveling Mmelite

Ngwongwo nhazi nke mkpuchi na-ekpebi ịdị nro na ọdịdị nke ihe nkiri a mịrị amị. Ndị ọrụ ọkwa ọkwa na-arụ ọrụ site na usoro abụọ bụ isi:

• Mbelata esemokwu elu: na-eme ka ịgbasa na mkpụrụ osisi, na-ebelata ntụpọ dị ka bee oroma ma ọ bụ cratering.

• Ịgbanwe evaporation ihe mgbaze: Na-agbatị oge eruba, na-enye ohere ka mkpuchi ahụ dị larịị nke ọma tupu ọ gwọọ ya.

5.Antistatic arụmọrụ

Na ngwa eletrọnịkị, nkwakọ ngwaahịa na mpaghara ndị ọzọ, mkpuchi nwere ike ịgbakọ ụgwọ kwụ ọtọ n'ihi esemokwu, na-ebute ihe egwu nchekwa. Ndị na-ahụ maka ọgwụ antistatic (dịka ọmụmaatụ, cationic surfactants) na-eme ka mmiri dị n'ime ya mepụta oyi akwa na-eduzi n'elu mkpuchi, na-eme ka nkwụsị ụgwọ na ibelata ihe egwu electrostatic.

6.Antimicrobial na Fungicidal Nchekwa

Na gburugburu iru mmiri, mkpuchi na-adịkarị mfe maka uto microbial, na-eduga na mmebi ihe nkiri. Ndị na-ahụ maka ọgwụ nje na fungicidal (dịka ọmụmaatụ, ogige ammonium quaternary) na-egbochi mgbasa microbial, na-agbatị ndụ nchekwa na ịdịte aka ọrụ nke mkpuchi.

7.Gloss Enhancement and Slip Improvement

Ụfọdụ mkpuchi chọrọ nnukwu gloss ma ọ bụ dị larịị (dịka ọmụmaatụ, ngwá ụlọ ma ọ bụ mkpuchi ụlọ ọrụ). Ihe mgbakwunye na-egbukepụ egbukepụ na ihe mgbakwunye na-amị amị (dịka, waxes ma ọ bụ silicones) na-eme ka ngosipụta ihe nkiri na-ebelata ma na-ebelata esemokwu elu, na-eme ka ọnyà na-eguzogide ọgwụ na ihe ọkụkụ.

Surfactants na-arụ ọrụ dị iche iche na ụlọ ọrụ mkpuchi, site na ịkwalite arụmọrụ nhazi ruo n'ịkwalite ihe nkiri ikpeazụ, niile na-eme ka ikike nhazi ihu ha pụrụ iche. Na ọganihu nke eco-enyi na enyi mkpuchi mkpuchi na-arụ ọrụ dị elu, akwụkwọ akụkọ, ndị na-arụ ọrụ nke ọma, na ndị na-egbu egbu na-egbu egbu ga-anọgide na-elekwasị anya na nyocha teknụzụ mkpuchi n'ọdịnihu.
