Usoro nke ime emulsifiers

Ihe emulsifiers nri, nke a makwaara dị ka surfactants, bụ ihe ndị na-agbanwe mmiri mmiri na-enweghị ike ịbanye n'ụdị agbasasịrị (emulsions). Mgbe agbakwunyere nri, ha nwere ike belata esemokwu interfacial n'etiti mmanụ na mmiri, na-ekwe ka mmanụ ndị a na-apụghị ime eme (ihe hydrophobic) na mmiri (ihe ndị dị na hydrophilic) na-etolite emulsions kwụsiri ike dị ka ihe mgbakwunye nri.

Uru nha nha nke hydrophilic na oleophilic

N'ozuzu, emulsifiers nwere hydrophilicity siri ike na-etolite mmanụ / mmiri emulsions, ebe emulsifiers nwere ike hydrophilicity na-emepụta mmiri / mmanụ emulsions. Iji gosi nguzozi nke hydrophilic na lipophilic nke emulsifiers, a na-ejikarị uru HLB (ọnụahịa lipophilic lipophilic balance value), na-eji uru HLB na-anọchi anya hydrophilicity nke emulsifiers. Enwere ụzọ mgbako dị iche iche maka uru HLB,

Usoro dị iche: HLB = hydrophilicity nke otu hydrophilic - hydrophobicity nke otu lipophilic.

Usoro nhazi: HLB=hydrophilicity nke otu hydrophilic/hydrophobicity nke otu oleophilic

Enwere ike ikpebi uru HLB nke emulsifier ọ bụla site na ụzọ nnwale. Maka emulsifiers nwere 100% lipophilicity, HLB ha bụ 0 (nke paraffin wax na-anọchi anya ya), na ndị nwere 100% hydrophilicity, HLB ha bụ 20 (nke potassium oleate nọchiri anya ya), kewara n'ime nha 20 iji gosi ike hydrophilicity na oleophilicity ha. Ka uru HLB buru ibu, ka hydrophilicity na-esiwanye ike, yana uru HLB dị ntakịrị, oleophilicity na-esiwanye ike.

Ọnụ ọgụgụ ka ukwuu nke emulsifiers oriri bụ ndị na-abụghị ionic surfactants nwere ụkpụrụ HLB sitere na 0 ruo 20. A na-egosi ụkpụrụ HLB dị iche iche na ihe ndị yiri ya nke ndị na-abụghị ionic emulsifiers na tebụl; Uru HLB nke ionic surfactants bụ 0-40. Ya mere, emulsifiers nwere ụkpụrụ HLB <10 bụ tumadi lipophilic, ebe emulsifiers nwere ụkpụrụ HLB ≥ 10 nwere njirimara hydrophilic.

Maka emulsifiers agwakọtara, ụkpụrụ HLB ha nwere ihe mgbakwunye. Ya mere, mgbe agwakọtara abụọ ma ọ bụ karịa emulsifiers ma jiri ya mee ihe, enwere ike gbakọọ uru HLB nke emulsifier agwakọtara dabere na nha nha nke emulsifier ọ bụla n'ime ihe mejupụtara ya:

HLB,b =HLBA·A%+HLBb·B%

Na usoro,

HLB, b bụ uru HLB nke emulsifier a, b gwakọtara ọnụ;

HLB na HLBb bụ ụkpụrụ HLB nke emulsifiers a na b, n'otu n'otu;

A% na B% bụ ihe dị n'ime pasentị nke a na b na emulsifier agwakọtara, n'otu n'otu (usoro a na-emetụta naanị emulsifiers na-abụghị ionic).
Ụzọ nkwadebe na ihe na-emetụta emulsifiers

Enwere ụzọ anọ maka ịkwadebe emulsifiers, ya bụ usoro gel akọrọ, usoro gel mmiri, usoro ngwakọta mmanụ-mmiri, na usoro igwe.

Usoro gel akọrọ, nke gụnyere ịtinye mmiri na mmanụ mmanụ nwere emulsifiers. N'oge nkwadebe, a na-ebu ụzọ gwakọta ntụ ntụ roba (emulsifier) ​​nke ọma na mmanụ, a na-agbakwunye mmiri ụfọdụ, ala na emulsified n'ime colostrum, wee gbanye ya na mmiri ruo n'uju.

Usoro gel wet, nke gụnyere ịgbakwunye mmanụ na oge mmiri nwere emulsifiers. N'oge nkwadebe, a na-agbaze gel (emulsifier) ​​na mmiri mbụ iji mepụta slurry dị ka mmiri mmiri. Mgbe ahụ, a na-etinye mmanụ mmanụ n'ime mmiri na nkebi, na-agbanye n'ime colostrum, na-agbakwunye mmiri na oke zuru ezu.

Gwakọta mmanụ na mmiri mmiri ma tinye ha na emulsifier, na-agwakọta ụfọdụ mmanụ na mmiri. Ghichaa chịngọm Arab n'ime ngwa agha, wee gwerie ngwakọta mmanụ-mmiri ngwa ngwa ka ọ bụrụ colostrum, ma gbanye ya na mmiri.

Nkwadebe nke emulsifiers na-agụnye emulsifying mmiri mmiri abụọ, na àgwà nke emulsification nwere mmetụta dị ukwuu na àgwà nke emulsion.
