Waa maxay taxaddarrada lagu cabbirayo viscosity hydroxypropyl methyl celluloseHPMC?Marka aan tijaabino viscosity ee cellulose.Si loo hubiyo saxnaanta natiijooyinka imtixaannada, waa in fiiro gaar ah loo yeesho afartan arrimood ee soo socda.
1. Tilmaamayaasha waxqabadka qalabku waa inay buuxiyaan shuruudaha xeerarka hubinta cabbirka ee qaranka.
Thehydroxypropyl methyl celluloseQalabka cabbiraadda viscosity-ka waxaa loo isticmaalaa wareegga tijaabada.Haddii loo baahdo (qalabka inta badan loo isticmaalo ama xaalad halis ah oo u qalma), is-imtixaan dhexdhexaad ah ayaa la sameeyaa si loo hubiyo in waxqabadka cabbirku uu yahay mid u qalma oo qaladka isku-dhafka ahi uu ku dhex jiro xadka la oggol yahay, haddii kale xogta saxda ah lama heli karo.
2. Fiiro gaar ah u yeelo heerkulka dareeraha la cabbirayo.
Isticmaalayaal badan ayaa iska indhatiray tan waxayna u maleynayaan in heerkulku uu ku dhow yahay mid aan khusayn.Tijaabooyinkeenu waxay muujinayaan in: marka heerkulku weecan yahay 0.5 ℃, leexashada viscosity ee dareerayaasha qaarkood ayaa ka badan 5%.Weecsanaanta heerkulku waxay saameyn weyn ku leedahay viscosity, heerkulka iyo viscosity.Sidaa darteed, waa in taxaddar gaar ah loo yeeshaa in heerkulka dareeraha la cabbiray lagu hayo meel u dhow halka heerkulka la cayimay, iyo cabbirka saxda ah, waxa fiican in aan ka badnayn 0.1 ℃.
3. Doorashada weelka cabbiraadda (tuubada dibadda).
Viscometer-ka wareega ee laba foosto, si taxadar leh u akhri buug-gacmeedka qalabka oo u dhig rotor-ka (salulubada gudaha) si waafaqsan.Dhululubo dibadda ah, haddii kale natiijada cabbiradu aad bay u leexan doontaa.Fiiskoometer wareeg ah oo hal dhululubo ah, dhexroorka dhululubada dibadda waa inuu noqdaa mid aan xad lahayn.Cabbirka dhabta ahi wuxuu u baahan yahay in dhexroorka gudaha ee dhululubada dibadda aanu ka yarayn cabbir cayiman.Tusaale ahaan, NDJ-1 viscometer rotary wuxuu u baahan yahay weel cabbiraya ama weel tuubo toosan oo aan ka yarayn 70 mm dhexroor.Tijaabooyinku waxay muujiyeen in khaladaadka cabbirka ee waaweyn ay keeni karaan haddii dhexroorka gudaha ee markabka uu aad u yar yahay, gaar ahaan marka rotor no.1 ayaa la isticmaalaa.
4, si sax ah u dooro rotor-ka ama hagaajiso xawaaraha, si qiimaha korontadu u dhexeeyo 20-90.
Qalabka noocaan ah wuxuu isticmaalaa garaaca iyo akhrinta tilmaamayaasha, iyo isku darka xasilloonida iyo leexashada akhrisku waxay leeyihiin 0.5 xabbo.Haddii akhrisku aad u yar yahay, oo ku soo wajahan yahay 5 xayndaab, qaladka qaraabo wuxuu noqon karaa in ka badan 10%.Haddii rotor-ka saxda ah la doorto ama akhriska xawaaraha uu yahay 50, khaladka qaraabada ah waxaa lagu dhimi karaa 1%.Haddii qiimuhu muujiyo in ka badan 90, torque ka soo baxa guga waa mid aad u weyn, taas oo u nugul in ay gurguurto oo ay dhaawacdo timaha, sidaas darteed waa in aan si sax ah u dooran rotor iyo xawaaraha.
Warqadani waxa ay soo bandhigaysaa arrimaha u baahan in fiiro gaar ah loo yeesho marka la cabbirayo viscosity of hydroxypropyl methyl cellulose, iyada oo rajaynaysa in waxa kor ku xusan ay kaa caawin karaan tijaabinta.KIMA kiimikowaxay u hoggaansamaan mabda'a "hal-abuurnimo, macmiilka ugu horreeya, tayada ugu horreysa".Fikradda horumarinta ganacsigu waa in la dhiso kalsoonida iyo horumarka muddada-dheer, si joogto ah u cusboonaysiinta qalabka iyo tignoolajiyada, ilaalinta deegaanka cagaaran iyo horumarinta farsamada sare.Shirkaddu waxay diyaar u tahay inay la shaqeyso alaab tayo sare leh oo gudaha iyo dibedda ah iyo saaxiibo muddo dheer, iskaashi daacad ah.
