Izixhobo zokuxuba i-vacuum zelabhoratri zibalulekile kuphando lwefomula kunye nemveliso encinci kwimveliso yezithambiso, amayeza kunye namashishini eekhemikhali ezintle. Ukukhetha isixhobo esingabizi kakhulu nesifanelekileyo esihambelana neemfuno zovavanyo, abasebenzisi kufuneka bavavanye ngokupheleleyo iiparameter ezininzi eziphambili. Izinto eziphambili zokukhetha zishwankathelwe ngolu hlobo lulandelayo.
1. Ukulinganisa ivolumu yokusebenza
Inkcazelo yomthamo yeyona iphambili yokukhetha. Iimodeli eziqhelekileyo ziquka i-1L, i-2L kunye ne-5L. I-reactor yeglasi ye-2L inomthamo ophezulu we-emulsifying we-2000ml kunye nomthamo omncinci we-emulsifying osebenzayo we-600ml. Abasebenzisi kufuneka bakhethe iimodeli ngokwemilinganiselo eqhelekileyo yovavanyo. Uvavanyo lwe-micro-sample luhambelana nemodeli ye-1L, ngelixa uvavanyo oluqhelekileyo lwe-medium-batch lufanelekile ngakumbi kwinguqulelo ye-5L, luphepha ukuxubana okunganelanga okubangelwa ngumthamo ongalinganiyo.
2. Ukuguquguquka kobungqindilili bezinto
Iifomyula ezahlukeneyo zineempawu ezahlukeneyo ze-viscosity. Umxube we-vacuum oqhelekileyo we-2L unokucubungula izinto ezine-viscosity ephezulu ye-100,000cP, egubungela uninzi lwee-lotions zemihla ngemihla kunye neekhrimu. Kwizinto ezinobukrakra obuphezulu ezifana nee-ointments ezityebileyo kunye nee-pastes, kuyimfuneko ukuphucula amandla okuxuba kunye nesakhiwo se-PTFE sokususa udonga ukuqinisekisa ukuxubana okufanayo kunye nokuthintela ukunamathela kwezinto kunye neendawo ezifileyo eziseleyo.
3. Ukusebenza koLawulo loBushushu
Ubushushu obuphezulu bokusebenza kwesi sixhobo yi-120°C. Sixhotyiswe ngebhafu yeoyile exhasa ubushushu obungaguqukiyo, uluhlu lokufudumeza lungafikelela kwi-300°C ngokuchanekileyo kwe-±0.5°C. Kwiimvavanyo ezifuna ukunyibilika nokufakelwa kobushushu obuphezulu, inkqubo epheleleyo yolawulo lobushushu iyimfuneko. Kwiimvavanyo ezilula zokuxuba okubandayo, abasebenzisi banokususa izixhobo zokufudumeza ezincedisayo ukuze bonge iindleko.
4. Umthamo wokusebenza kweVacuum
Ipompo yokufunxa efrijini ehambelanayo inokugcina iqondo lokukhupha umoya elizinzileyo le--0.096MPa iiyure ezingama-24, nto leyo esusa ngempumelelo amaqamza omoya kwaye iphucule ubunono bemveliso. Olu lungiselelo luyimfuneko kwiindlela zokhathalelo lolusu eziphezulu kunye nee-emulsions zonyango. Kwiimvavanyo ezingenazo iimfuno zokufunxa, iipompo zokufunxa eziqhelekileyo zingasetyenziswa njengenye indlela.
5. Isiphumo sokuxukuxa kunye nokuHlanganisa
Ulwakhiwo lwamandla amabini lokuxukuxa eludongeni ngesantya esiphantsi kunye nokuxukuxa ngesantya esiphezulu (0-30000rpm) kuqinisekisa ukusasazwa kwezinto ezincinci kunye nokuxukuxa. Abasebenzisi banokulungisa uqwalaselo lwamandla e-homogenizer ngokweemfuno zokuchaneka kovavanyo ukulinganisela ukusebenza komsebenzi kunye nohlahlo-lwabiwo mali.
Ukuqukumbela, ukhetho olufanelekileyo lufanele ludibanise iimeko zovavanyo zangempela. Kuphela ngokuthelekisa umthamo, ukumelana nokuxinana, ubushushu kunye neeparamitha zevacuum apho abasebenzisi banokuthenga izixhobo zokuxuba ivacuum cleaner ezifanelekileyo kakhulu kwilebhu.
