Uxinano lweMethanol lucacisiwe: Iimpawu, umlinganiselo kunye nezinto ezichaphazelayo
Isishwankathelo seMethanol Density
I-Methanol (ifomula yeekhemikhali: CH₃OH) yinto ebalulekileyo yeekhemikhali ekrwada, kwaye ukuxinana kwayo yiparameter yomzimba ebalulekileyo elinganisa ubudlelwane bayo obukhulu kunye nomthamo. Ulwazi kunye nokuqonda ukuxinana kwemethanol kubalulekile kwimveliso yemizi-mveliso, ukusetyenziswa kweekhemikhali kunye nokuthutha. Ngesiqhelo, ukuxinana yipropathi yendalo kwaye inxulumene ngokusondeleyo neemeko ezifana nobushushu kunye noxinzelelo. Kweli nqaku, siza kuxubusha ngokubanzi iimpawu ze-methanol density, iindlela zayo zokulinganisa kunye nezinto ezichaphazelayo, ukukunceda uqonde kangcono le parameter ebalulekileyo.
Iimpawu ezisisiseko ze-methanol density
Ubuninzi bemethanol budla ngokubonakaliswa ngokomthamo weyunithi nganye yobunzima bemethanol, kwaye kwiimeko eziqhelekileyo (okt, 20°C kunye ne-1 atm), ubuninzi bemethanol bumalunga ne-0.7918 g/cm³. Kubalulekile ukuba uqaphele ukuba eli xabiso lihluka ngokushisa kunye noxinzelelo, ngoko ubuninzi bunokwahluka kancinci phantsi kweemeko zokusebenza ezahlukeneyo. Ukuqonda iimpawu ezisisiseko ze-methanol density kunceda kwimitha echanekileyo kunye nolawulo lokuphendula kwiinkqubo zemichiza.
Izinto ezichaphazela ukuxinana kwemethanol
Impembelelo yeqondo lokushisa kwi-methanol density
Ubushushu yenye yezona zinto zibalulekileyo ezichaphazela ukuxinana kwemethanol. Njengoko iqondo lokushisa lisanda, amandla e-kinetic eemolekyuli ze-methanol ayanda kwaye umgama phakathi kweeamolekyu uyanda, okukhokelela ekunciphiseni kobuninzi. Umzekelo, kwiqondo lobushushu begumbi (20°C), imethanol inoxinano lwe-0.7918 g/cm³, eyehla ukuya ku-0.762 g/cm³ xa ubushushu bonyuswa ukuya ku-60°C. Oku kuxhomekeka kweqondo lokushisa kufuneka kuthathelwe ingqalelo kwizicelo eziphathekayo, ngakumbi apho imisebenzi yokushisa ephezulu ibandakanyeka okanye apho umthamo we-methanol kufuneka ulinganiswe ngokuchanekileyo.
Impembelelo yoxinzelelo kwi-methanol density
Nangona impembelelo yoxinzelelo kubuninzi be-liquid idla ngokuba yincinci, kwindawo yoxinzelelo oluphezulu le nto ayinakuhoywa. Uxinzelelo olonyukayo lunyanzela ukuba imigama ephakathi kweeathom yehle, ngaloo ndlela inyusa kancinci ingxinano yemethanol. Kulwelo olufana ne-methanol, utshintsho kuxinaniso ngenxa yoxinzelelo ludla ngokungacaci kangako kunotshintsho kwiqondo lobushushu. Ngoko ke, umphumo woxinzelelo kubuninzi be-methanol unokuthathwa njengesibini phantsi kweemeko eziqhelekileyo zokusebenza, kodwa le nto isafuna ukuqwalaselwa kwizixhobo zeekhemikhali eziphezulu zoxinzelelo.
Iindlela zokulinganisa ubuninzi bemethanol
Indlela yokulinganisa elebhu
Kwilabhoratri, ingxinano yemethanol idla ngokulinganiswa kusetyenziswa ibhotile ethile yomxhuzulane okanye i-densitometer. Indlela yebhotile yomxhuzulane okhethekileyo yindlela yokulinganisa ingxinano yeklasiki, apho ingxinano ibalwa ngokulinganisa ubunzima bebhotile ethile yomxhuzulane ezaliswe lulwelo. I-densitometer sisixhobo esilinganisa ngokuthe ngqo ingxinano yolwelo kwaye sigqibe ukuxinana kolwelo ngomgaqo wobuoyancy bokudada. Zombini iindlela zineengenelo kunye nezingeloncedo zazo, eyokuqala ichanekile kakhulu kodwa inzima ukusebenza, le yokugqibela ilula ukuyisebenzisa kodwa ifuna ukulinganiswa okuphezulu kwesixhobo.
Umlinganiselo woshishino kwi-intanethi
Kwimveliso yemizi-mveliso, ukujonga ixesha lokwenyani lokuxinana kwemethanol kubalulekile kulawulo lwenkqubo. Izixhobo zokulinganisa ubuninzi be-intanethi ezisetyenziswa ngokuqhelekileyo ziquka i-densitometers ye-tube engcangcazelayo kunye ne-ultrasonic densitometers. I-densitometers yetyhubhu engcangcazelayo imisela ubuninzi ngokulinganisa i-resonant frequency yolwelo ngaphakathi kwityhubhu engcangcazelayo, ngelixa i-ultrasonic densitometers ifumana ukuxinana kwisantya samaza e-ultrasonic ahamba kulwelo. Ezi zixhobo zibonelela ngedatha yexesha langempela ngexesha lenkqubo yokuvelisa ukuqinisekisa ukuba iimeko zokusebenza ziphakathi kwemida efanelekileyo.
Ubuninzi beMethanol kwishishini lemichiza
Ukuzimisela okuchanekileyo kunye nokulawulwa koxinaniso lwe-methanol kunoluhlu olubanzi lwezicelo kwishishini lemichiza. Umzekelo, kubunjineli bokusabela, ingxinano yiparameter ephambili kwi-accounting yezinto eziphathekayo kunye nokubalwa kwamandla. Xa ugcina kwaye uhambisa i-methanol, idatha yoxinaniso inokunceda ukugqiba umthamo wokuzaliswa kweetanki zokugcina kunye nokulayishwa kwezithuthi zokuthutha. Idatha yoxinaniso ingasetyenziselwa ukubeka esweni ukucoceka kwemethanol, njengoko ubukho bobumdaka buhlala bukhokelela kwiiyantlukwano ezingaqhelekanga kuxinano.
Isishwankathelo
Ubuninzi beMethanol yiparameter ephambili kwishishini lemichiza, echaphazela imiba emininzi yokusebenza kunye nokuyila. Ngokuqonda iipropati zayo, iindlela zokulinganisa kunye neempembelelo ezichaphazelayo, iingcali zoshishino lweekhemikhali ziyakwazi ukulawula kakuhle inkqubo yokuvelisa, ukwandisa ukusetyenziswa kwezixhobo kunye nokuqinisekisa ukhuseleko lwemveliso kunye nokusebenza kakuhle. Ukulungelelanisa ukuqonda kunye nokusetyenziswa kwe-methanol density phantsi kweemeko ezahlukeneyo yindlela ebalulekileyo yokuphucula ukusebenza kwemizi-mveliso.
