Abaninzi abavelisi beemveliso zeekhemikhali baya kuhlawula ngakumbi ukuzinza kwe-emulsification ekuphuhlisweni kweemveliso, kuba ukuzinza kweemveliso kuhambelana nomgangatho wezimonyo. Iimveliso ezikumgangatho ophezulu zinokudala igama kumashishini, ngoko ke abavelisi bezithambiso ekukhetheni izixhobo ze-emulsification kufuneka baqonde. Oku kulandelayo kwazisa impembelelo yezixhobo ze-emulsification ekuzinzeni kwe-emulsification yemveliso, indlela yokukhetha isixhobo esifanelekileyo sokulinganisa?
1. Ingqikelelo ye-emulsification
I-Emulsion yinto yojongano lwe-liquid, ulwelo ezimbini ezinganyibilikiyo, njenge-oyile kunye namanzi, zohlulwe zibe ngamaleko amabini kwisitya, kunye ne-oyile exineneyo encinci kumaleko aphezulu kunye namanzi axinene ngakumbi kumaleko asezantsi. Ukuba i-surfactant efanelekileyo yongezwa phantsi kokuvuselela okunamandla, ioli ihlakazwa emanzini ukuze yenze i-emulsion, inkqubo ibizwa ngokuba yi-emulsification.
2. Impembelelo yezixhobo ze-emulsification ekuzinzeni kwe-emulsification yeemveliso
Umatshini wokuxuba oqhelekileyo we-emulsion, ukusabalalisa kunye nokuzinza kwe-emulsion akubi, kwaye amasuntswana makhulu kwaye arhabaxa, ukuzinza kubi kakhulu, kodwa kulula ngakumbi ukuvelisa ungcoliseko. Ngoko ke, umgangatho wezinto zokuthambisa eziveliswayo unokuba yinto eqhelekileyo, kwaye amava omthengi akayi kuba kuhle kakhulu.
Ukuzinza kwemveliso egqityiweyo ngokubanzi kubi kakhulu, umgangatho awukho kakuhle, unokwenza kuphela iimveliso ezisezantsi ezinobuchwephesha obulula. Oku akuncedi kuphuhliso lwexesha elide lwamashishini.
3. Vacuum homogenization kunye nomatshini emulsification
Ngophuhliso lwetekhnoloji ye-emulsification kwiminyaka yakutshanje, umatshini weZhitong uye wazisa ubuchwephesha bemveliso yangaphandle ngenkuthalo, waphuhlisa kwaye wavelisa umatshini we-vacuum homogeneous emulsification ukuqatshelwa kunye nenkxaso yabathengi bayo.
Vacuum homogenization umatshini emulsifyingyiseti epheleleyo yenkqubo yokudibanisa ukuxuba, ukusabalalisa, i-homogenization, i-emulsification kunye ne-powder absorption. Ukusebenzisa amandla e-kinetic anamandla aziswa ngoomatshini, izinto ezikwisithuba esimxinwa se-rotor kunye ne-stator, inokumelana namakhulu amawaka e-liquid force shear yonke iminithi, iimveliso ze-emulsifying zangoko.
Sukuba nexhala malunga neemveliso kwinkqubo yokuvelisa emoyeni, yenza amaqamza emveliso, ungcoliseko lwebhaktheriya, i-oxidation elula kunye nenkangeleko ayigudi, ukusebenza kwenkqubo yokucoca akuyi kubonakala kule meko, i-vacuum (0.095MPa) phantsi kwemeko emulsification esasazekileyo ngoko nangoko, hayi kwinkqubo yokuvelisa amaqamza, ngoko inokuqinisekisa ubuthathaka kwaye uzinzile.
