Ukuchazwa kweempawu zoMgangatho kunye noHlalutyo lweeNto ezichaphazelayo kwi-HIGH SHEAR umxube I-GRANULATION
Itekhnoloji ye-High Shear Mixer Granulation isetyenziswa kakhulu kwicandelo lamalungiselelo aqinileyo amayeza. Le teknoloji idla ngokudibanisa izinto ezikrwada kunye nezinye izinto ezisetyenzisiweyo.I-CIPi-ients ngokulinganayo ukwenza amasuntswana angama-180-2000 μ m, asetyenziswa kwiinkqubo ezisezantsi ezifana nokucinezelwa kwethebhulethi, ukuzaliswa kwekhaphu, kunye nokufakwa kwengxowa yamasuntswana. Ukuphunyezwa kwenkqubo yokuxubana okumanzi kubalulekile ekunikezeleni amasuntswana asemgangathweni ophezulu nafanelekileyo asezantsi. Iimpawu zamasuntswana zichaphazela iimpawu eziphambili zomgangatho weemveliso, ezifana nesantya sokunyibilika, umahluko kubunzima bethebhulethi (umahluko kumthamo wokulayisha), njalo njalo. Ngokwesiqhelo, singavavanya amasuntswana ngokusekelwe kwizalathisi ezibonakalayo ezifana nokusasazwa kobungakanani bamasuntswana, ukubola, umxholo womswakama, kunye nokuhamba kakuhle. Isivuno sobungakanani bamasuntswana ekujoliswe kuwo sibhekisa kwipesenti yamasuntswana ahlangabezana noluhlu lobungakanani bamasuntswana olulindelekileyo kwimveliso yokugqibela ukuya kubunzima bamasuntswana apheleleyo, anokulinganiswa ngokuhlola, nge-laser, kunye neendlela zomfanekiso. Ngokwemigangatho yoshishino i-JB/T 20015, umgangatho wovavanyo lokusebenza kwamasuntswana okuxubana okumanzi kukuba izinga lamasuntswana estatshi sombona, i-dextrin, kunye nomgubo weswekile kumlinganiselo we-3:2:1 emva kokomiswa akufuneki libe ngaphantsi kwe-75% ngaphakathi koluhlu lwe-180-2000 μ m. Amashishini aqinisekisa ubungakanani be-particle ye-granulation emanzi ngokusekelwe kwiimfuno zenkqubo esezantsi, kwaye uluhlu lobungakanani be-particle kunye nesantya se-particle zixhomekeke kwiimfuno ezithile zemveliso. Ukusasazwa kobungakanani be-particle kuchaza umlinganiselo wee-particles zobukhulu obahlukeneyo kwinkqubo ye-particle, ngelixa i-dispersion degree ilinganiswa ngobubanzi bokusasazwa kobungakanani be-particle. Ukusasazwa kobungakanani be-particle kufunyanwa ngeendlela zezibalo ngokusekelwe kwiziphumo zokufunyanwa kobungakanani be-particle. Nokuba i-target particle size ifana, kusenokubakho umahluko omkhulu ekusasazekeni kobungakanani be-particle. Kwiiziyobisi ezininzi, sikhetha i-particle dispersion encinci ngaphakathi koluhlu lwe-vintage olulindelekileyo lobungakanani be-particle target ukuqinisekisa ukuhambelana kwisiphumo sokunyibilika kwezonyango. Ububanzi be-particle distribution Span busetyenziswa rhoqo ukulinganisa i-degree of dispersion of particle distribution. Indlela yokubala yile ilandelayo: (1) Kwi-equation: D90- ububanzi be-particle obuhambelana nokubalwa okuqokelelweyo kobukhulu be-particle ukusuka kuncinci ukuya kukhulu okufikelela kwi-90% yetotali, μm； D10- ububanzi be-particle obuhambelana nokubalwa okuqokelelweyo kobukhulu be-particle ukusuka kuncinci ukuya kukhulu okufikelela kwi-10% yetotali, μm； D50- ububanzi be-particle obuhambelana nokubalwa okuqokelelweyo kobukhulu be-particle ukusuka kuncinci ukuya kukhulu okufikelela kwi-50% yetotali, μm。 Okukhona i-span inkulu, kokukhona umahluko omkhulu kubukhulu be-particle kwaye kokukhona ubufana buthathaka; Ngokwahlukileyo koko, kokukhona ifana ngakumbi. Umfanekiso 1 ubonisa umahluko kububanzi bokusasazwa kobukhulu be-particle bee-particle ezilungiselelwe kusetyenziswa izinto ezifanayo ezikrwada kunye neeparamitha zenkqubo ezahlukeneyo. Kuyabonakala ukuba nangona isivuno sobukhulu be-particle ekujoliswe kuso se-180-2000 μ m sifana, umahluko kububanzi bokusasazwa kobukhulu be-particle ubalulekile (i-curve eluhlaza okwesibhakabhaka inexabiso elincinci le-Span, i-curve etyheli inexabiso eliphakathi le-Span, kwaye i-curve e-orenji inexabiso elikhulu le-Span). Ngoko ke, ukukhetha ixabiso elifanelekileyo leSpan ngokusekelwe kwiimfuno zenkqubo yeyona nto ibalulekileyo ekuphononongeni ukusebenza kakuhle kwe-wet granulation.
