Masithethe malunga ne-hydroxypropyl methyl seluploseI-HPMCKwaye indlela yokulinganisa uVeksity. I-viscosity apha ibhekisa ku-Viskosity ebonakalayo, eyireferensi ebalulekileyo kwi-Hydroxyl Goutyl Goutlose.
Umgangatho. Iindlela zokulinganisa eziqhelekileyo ziyimilinganiselo yokubonisa yokuhamba-mbala, i-capillary viscofity vissosity kunye nemilinganiselo ye-viscosity. Indlela yokumisela indlela ye-hydroxypropyl methyl seluplose yayiyintloko ye-Capillary.
Indlela yokuzimisela idigri, usebenzisa i-Uchs Vimer. Ngokwesiqhelo ukumiselwa kwesisombululo sisisombululo se-2%, ifomula yile: v = kdtt. V luhlobo lwe-MPA. S kunye ne-k nguVile vimet rhoqo.
D kukuxinana kwiqondo lokushisa rhoqo kwaye lixesha ukusuka phezulu ukuya ezantsi ngophawu ngemizuzwana. Le ndlela yokusebenza inamandla ngakumbi, ukuba kukho umbandela onxungupheleyo.
Amagama kulula ukubangela iimpazamo, kunzima ukubonisa umgangatho we-hydroxypropy ye-methyl sellyulose. Ngoku isetyenziselwa ukulinganisa i-viscofity yendawo yokundwendwela ejikelezayo, ukusetyenziswa ngokubanzi eChina.
Ifomula ye-NDJ-1 Vimermieter yi-η = kcy. η ngumbono, nakwi-MPA. S, k kukulingana kophawu, kwaye α kukufundwa kwesikhombisi sokubona.
I-HydroxyPOpyl Methyl Selelose 2% yendlela yokuvavanya i-viscosity:
1, Le ndlela ilungele ukumiselwa kolwelo olunamandla lwe-Faltonsian yolwelo (isisombululo sePolymer, ukumiswa, ukusasazeka kwe-eulsion, njl. Njl.).
2. Izixhobo kunye nezinto zombane
2.1 I-ROVERERTERTTER (NDJ-1 kunye ne-NDJ-4 ifunwa nguShiner Pharmacopoeia)
2.2 Iqondo lobushushu lamanzi lokuhlambela amaqondo obushushu e-0.10c
2.3 Inqanaba lobushushu lokufumana i-0.20c, eqinisekiswe ngamaxesha ngamaxesha.
2.4 Iimpawu ze-frequency meter vimeters zisebenzisa iindlela ze-frequaverathare (ezinjenge-NDJ-1 kunye ne-NDJ-4) ziya kugcinwa. Ukuchaneka kwe-1%. A
8. Isampulu ye-Og yaye yangena ngokuchanekileyo kwaye yafaka i-baaker eyomileyo, enomileyo ye-400ml ubude. Yongeza malunga ne-100ml ye-80-90 i-80-90 AMANZI AMANZI AMANZI AMANDLA AMAHLA WOKUGQIBELA WOKUGQIBELA
Ukuhlambela ngokulinganayo, kuyashukumisa kwaye wongeze amanzi abandayo ukuya kwi-400ml iyonke. Okwangoku, qhubeka ngokuqhubekayo kwi-30min ukwenza isisombululo se-2% (W / W), kwaye siyibeke kwifriji yokuhlambela i-ice i-ice i-ice i-Ice de ibe senze umkhenkce.
Khupha kwaye ubeke itanki yobushushu ehamba-hamba ukuze ugcine ubushushu obuphakathi ukuya kwi-20 ℃ 0.1 ℃.
3.1 ufakelo kunye nokusebenza kwesixhobo kuya kwenziwa ngokuhambelana nomyalelo osebenzayo wesixhobo, kwaye i-rotor efanelekileyo kunye nengcwanguya kuya kukhethwa ngokwemveliso yokuvavanywa kwemveliso evavanyiweyo
Isantya esijikelezileyo.
3.2 Uhlengahlengiso lobushushu bamanzi ngamanzi ngamanzi ngokungqinisisa phantsi kwento nganye yeziyobisi.
3.3 Imveliso yovavanyo yabekwa kwisikhongozeli echazwe sisixhobo, kwaye i-angle yokuchasa (a) yalinganiswa ngokomthetho emva kwemizuzu engama-30 yeqondo lokushisa. Cima i-motor kwaye uqalise kwakhona ukuze uzimisele kube kanye
Umahluko phakathi kwamaxabiso athile akufuneki adlule kwi-3%, kungenjalo umlinganiso wesithathu kufuneka wenziwe.
3.4 Bala ixabiso elichanekileyo leemvavanyo ezimbini ngokwendlela yokufumana i-viscosity eguqukayo yemveliso evavanyiweyo.
4. Rekhoda kwaye ubale
4.1 Rekhoda imodeli yeVidiyo yeVidiyo, iNdawo yeRotor kunye nesantya esisetyenzisiweyo, i-vismesters ihlala (k 'ixabiso), iqondo lobushushu, kunye nomlinganiso ngamnye. Ixabiso.
Ifomula ebalwayo ye-4.2
I-viscosity ye-Dynamic (MPA "s) = ka apho kuphi na i-k i-visment ye-visment ilinganiswe ngolwelo olusezantsi lwe-viscofity eyaziwayo kunye ne-angle ye-chaclection
