Qalabka Emulsifying
Qalabka ugu muhiimsan ee farsamada ee diyaarinta emulsion waa mashiinka emulsifying, kaas oo ah nooc ka mid ah qalabka emulsifying si siman u walaaqaya saliidda iyo biyaha. Waqtigan xaadirka ah, waxaa jira saddex nooc oo waaweyn oo emulsifying machine: emulsifying mixer, kolloid Mill iyo homogenizer. Emulsifying mashiinka nooca iyo qaab-dhismeedka, waxqabadka iyo cabbirka qayb ka emulsion ah (kala firdhiyey) iyo tayada emulsion ah (xasiloonida) waxay leedahay xiriir weyn. Guud ahaan, sida hadda si ballaaran loo isticmaalo warshadda isku qurxiyo walaaqaya emulsifier, emulsion ah oo ay soo saartay kala firidhsan saboolka ah. Qaybaha ayaa ah kuwo waaweyn oo qalafsan, oo leh xasilooni xumo iyo wasakh fudud. Laakiin wax-soo-saarkeedu waa mid fudud, qiimuhu waa raqiis, ilaa inta aad fiiro gaar ah u leedahay qaab-dhismeedka macquulka ah ee mashiinka, u isticmaal si habboon, laakiin sidoo kale waxay soo saari kartaa shuruudaha tayada guud ee isku dhafan ee qurxinta caanka ah. Warshadaynta Colloid iyo homogenizer ayaa ah qalab ku-midaynta ka wanaagsan. Sanadihii la soo dhaafay, mishiinada emulsifying ayaa sameeyay horumar weyn, sida mashiinka emulsifying vacuum, emulsion ay diyaarisay kala firdhinta iyo xasiloonida aad u fiican.
Heerkulka
Heerkulka emulsification wuxuu saameyn weyn ku leeyahay emulsification, laakiin ma jiro xad adag oo heerkulka ah. Haddii saliidda iyo biyuhu ay dareere yihiin, waxaa lagu walaaqayaa heerkulka qolka. Guud ahaan, heerkulka emulsification wuxuu ku xiran yahay barta dhalaalka ee walxaha leh barta dhalaalka sare ee labada weji, iyo arrimo ay ka mid yihiin nooca emulsifier-ka iyo milanka wajiga saliidda iyo wajiga biyaha waa in la tixgeliyaa. Intaa waxaa dheer, heerkulka labada weji waa in lagu hayaa ku dhawaad isku mid, gaar ahaan qaybaha wajiga dhuka iyo baruurta leh barta dhalaalaysa sare (ka sarreeya 70 ℃), marka emulsifying, heerkulka hooseeya wajiga biyaha waa in aan lagu darin, si ay u Ka ilaali dhuka iyo dufanka inay dhalaan ka hor inta aan la emulsion, taasoo keenta emulsion weyn ama mid aan fiicneyn oo aan sinnayn. Guud ahaan, marka emulsifying, heerkulka saliidda iyo biyaha waxaa lagu xakamayn karaa inta u dhaxaysa 75 ℃ iyo 85 ℃. Haddii marxaladda saliiddu leedahay dhuxul dhibic dhalaalaysa sare iyo qaybaha kale, heerkulka emulsifying noqon doonaa sare waqtigan. Intaa waxaa dheer, haddii viscosity si weyn u kordho habka emulsification, waxa loogu yeero aad u dhumuc weyn oo saameeya isku dhafka, heerkulka emulsification qaar ka mid ah ayaa si habboon kor loogu qaadi karaa. Haddii emulsifier-ka la isticmaalo uu leeyahay heerkul kala-guur waji gaar ah, heerkulka emulsifying ayaa sidoo kale si fiican loo doortaa agagaarka heerkulka kala-guurka wajiga. Heerkulka Emulsification mararka qaarkood wuxuu sidoo kale saameeyaa xajmiga walxaha emulsion-ka. Haddii emulsifier-ka anionic ee saabuunta aashitada dufanka leh guud ahaan la isticmaalo, cabbirka walxaha emulsion-ku wuxuu ku saabsan yahay 1.8-2.0μm marka heerkulka emulsification la xakameeyo 80 ℃. Haddii cabbirka qaybku uu ku saabsan yahay 6μm marka emulsification la sameeyo at 60 ℃. Saamaynta heerkulka emulsification ee cabbirka qaybtu waa daciif marka emulsifier-ka aan-ionic loo isticmaalo emulsification.
Waqti-ku-daynta
Waqtiga Emulsification si cad u saameyn ku tayada emulsion ah, iyo go'aaminta waqtiga emulsifying waa marka loo eego saamiga mugga ee wejiga biyaha saliidda, laba wejiga viscosity iyo dhalin viscosity ee emulsion ah, nooca iyo qiyaasta emulsifier ah, emulsifying. heerkulka, emulsifying wakhtiga inta, waa ku filan si ay u sameeyaan nidaamka emulsification, waxay si dhow ula xiriiraan waxtarka qalabka emulsification, waqtiga Emulsification. waxaa lagu go'aamin karaa iyadoo loo eegayo waayo-aragnimada iyo tijaabada. Emulsification leh homogenizer (3000 RPM) waxay qaadataa 3-10 daqiiqo oo keliya.
Xawaaraha isku dhafka
Qalabka Emulsification wuxuu saameyn weyn ku leeyahay emulsification, mid ka mid ah taas oo ah saameynta xawaaraha kicinta ee emulsification. Xawaaraha walaaqaya dhexdhexaadka ah waa in la sameeyo wajiga saliidda iyo biyaha si buuxda isku dhafan, xawaare aad u hooseeya, sida cad ma gaari karo ujeedada isku dhafka buuxa, laakiin xawaaraha sare ee sare, waxay keeni doontaa xumbo nidaamka, si ay u noqoto saddex- nidaamka wajiga, iyo ka dhigi emulsion aan degganayn. Sidaa darteed, hawada waa in laga fogaadaa isku darka, mashiinka emulsifying vacuum wuxuu leeyahay waxqabad aad u sarreeya.
