Hey! Olsem wanpela saplaia bilong ol 'emulsifier', planti taim ol i save askim mi long ol HLB veliu bilong ol narapela narapela 'emulsifier'. Orait, yumi go insait stret long en na lukim sapos ol narapela narapela 'emulsifiers' i gat ol narapela narapela HLB veliu.
Pastaim, wanem samting em HLB? HLB i makim Hydrophilic - Lipophilic Balance. Em i wanpela skel we i helpim yumi long save long hau wanpela 'emulsifier' i save wok insait long wanpela miks bilong wara na oil. HLB skel i stat long 0 i go inap 20. Sapos HLB i liklik (0 - 3) dispela i min olsem 'emulsifier' i gat moa 'lipophilic' (laikim oil -), na sapos HLB i antap (17 - 20) dispela i min olsem em i gat moa 'hydrophilic' (laikim wara -).
Nau, taim yumi toktok long ol narapela narapela 'emulsifiers', bekim em i tru olsem yes, ol i gat ol narapela narapela HLB veliu. Na dispela em i bikpela samting tru bikos HLB veliu bilong wanpela emulsifier inap long makim wok bilong en long ol narapela narapela aplikesen.
Yumi ken lukluk long sampela 'emulsifiers' na ol HLB veliu bilong ol. Wanpela bilong ol 'emulsifiers' we planti man i save long en em Span 20. Em i gat HLB veliu bilong 8.6. Span 20 em i moa 'lipophilic', na dispela i mekim em i gutpela long wokim wara - insait long - oil (W/O) emulsen. Ol dispela kain emulsen ol i save yusim long ol samting olsem ol krim na losen we yu laikim oil i mas stap oltaim.
Long narapela sait, mipela i gat Tween 80. Tween 80 i gat HLB veliu bilong samting olsem 15. Em i gat moa wara, olsem na em i gutpela tru long wokim oil - insait long - wara (O/W) emulsen. Ol 'O/W emulsions' i save stap long ol samting olsem 'salad dressings' na milk, we wara i save stap oltaim.
As bilong ol narapela narapela emulsifier i gat narapela narapela HLB veliu em i bikos long kemikel straksa bilong ol. Ol 'emulsifiers' i gat tupela hap we i save laikim wara na 'lipophilic'. Reshio bilong dispela tupela hap i makim HLB veliu. Olsem, wanpela 'emulsifier' we i gat bikpela 'hydrophilic' grup na liklik 'lipophilic' grup bai i gat bikpela HLB veliu, na wanpela we i gat bikpela 'lipophilic' grup na liklik 'hydrophilic' grup bai i gat liklik HLB veliu.
Tasol bilong wanem em i bikpela samting olsem ol narapela narapela 'emulsifier' i gat narapela narapela HLB veliu? Orait, sapos yu wokim wanpela prodak, yu mas makim stretpela emulsifier wantaim stretpela HLB veliu bilong ol spesifik nid bilong yu. Yumi ken tok olsem yu wokim wanpela sanskrin. Ol sanskrin i save gat wara na oil wantaim. Yu nidim wanpela 'emulsifier' wantaim HLB veliu we inap long kamapim wanpela gutpela O/W 'emulsion' bai 'sunscreen' i ken go isi long skin na i no ken bruk. Sapos yu makim wanpela 'emulsifier' we i gat rong HLB veliu, 'emulsion' inap bruk, na prodak bilong yu bai no inap wok gut.
Narapela samting yu mas tingim em olsem sampela taim, yu mas yusim wanpela 'blend' bilong ol 'emulsifiers' long kisim mak bilong HLB yu laikim. Ol i kolim dispela olsem 'emulsifier system'. Taim yu bungim tupela o moa emulsifier wantaim ol narapela narapela HLB veliu, yu ken stretim - olgeta HLB bilong sistem. Olsem, sapos yu nidim wanpela emulsifier wantaim HLB veliu bilong 10, na yu gat wanpela emulsifier wantaim HLB bilong 8 na narapela wantaim HLB bilong 12, yu ken miksim ol long stretpela mak bilong kisim veliu yu laikim.
Nau, mi laik kolim wanpela gutpela risos we inap long givim yu moa infomesen long ol 'emulsifiers' na wok bilong testim ol. Yu ken sekim4-testsdfgsdfg. Em i gat sampela gutpela data na tingting we inap long helpim yu long kliagut moa long ol 'emulsifiers'.
Olsem wanpela saplaia bilong 'emulsifier', mi lukim stret olsem em i bikpela samting long makim stretpela 'emulsifier' wantaim stretpela HLB veliu. Mipela i save givim planti kain 'emulsifiers' wantaim ol narapela narapela HLB veliu bilong inapim ol kain kain nid bilong ol kastoma bilong mipela. Maski yu wok long indastri bilong kaikai, kosmetik, o narapela wok we i nidim ol 'emulsion', mipela i gat ol samting bilong helpim yu.
Sapos yu wok long wokim wanpela nupela prodak o yu laik stretim wanpela prodak we i stap pinis, orait yu mas kisim stretpela 'emulsifier' em i bikpela samting. Na dispela em i hap we mipela i kam insait long en. Tim bilong ol saveman bilong mipela i ken helpim yu long makim gutpela 'emulsifier' bihainim ol samting yu laikim. Mipela i klia olsem olgeta prodak i narakain, na mipela i gat strongpela tingting long givim yu ol gutpela - kwaliti emulsifiers we bai mekim ol fomulasen bilong yu i kamap gut.
Olsem na, sapos yu laik save moa long ol 'emulsifier' bilong mipela o yu gat sampela askim long ol HLB veliu na wanem 'emulsifier' i stret long yu, noken surik long toktok wantaim mipela. Mipela i stap hia long toktok wantaim yu, bekim ol askim bilong yu, na helpim yu long painim gutpela 'emulsifier solution'. Maski yu wanpela liklik - skel produsa o wanpela bikpela - skel manifakta, mipela i ken wok wantaim yu long inapim ol nid bilong yu long 'emulsifier'.
Long pinisim, ol narapela narapela emulsifier i gat ol narapela narapela HLB veliu, na ol dispela veliu i save mekim bikpela wok long wok bilong ol emulsen insait long ol kain kain prodak. Sapos yu kliagut long tingting bilong HLB na makim stretpela 'emulsifier', yu inap long kamapim ol gutpela prodak we i gat gutpela - kwaliti. Na olsem emulsifier saplaia bilong yu, mipela i redi long sapotim yu long olgeta step bilong rot. Orait, yumi ken statim dispela wokabaut wantaim na mekim prodak bilong yu i kamap gutpela tru!
