I-Methanol Density ichaze: Iimpawu, umlinganiso kunye nezinto ezichaphazela
Amagqabantshintshi e-Methanol Derity
I-Methanol (ifomula yekhemicamiki) yindawo ebalulekileyo yemichiza eluhlaza, kwaye uxinzelelo lwayo yiparamitha ebalulekileyo emanzini. Ulwazi kunye nokuqonda ukuxinana kweMethanol kubalulekile kwimveliso yemizi-mveliso, usetyenziso lwemizikhali kunye nezothutho. Ngokwesiqhelo, ukuxinana yipropathi yento yento kwaye inxulumene ngokusondeleyo nemeko efana neqondo lobushushu kunye noxinzelelo. Kweli nqaku, siza kuthetha ngokweenkcukacha iipropathi zeMethanol Ukuxinana, iindlela zayo zokulinganisa kunye nezinto ezichaphazela, ukukunceda ukuba uyiqonde ngcono le parameter ibalulekileyo.
Iipropati ezisisiseko zeMethanol Derity
Ukuxinana kwe-methanol kuhlala kuchazwe ngokwemigaqo yevolumu ye-methanol, nakwiimeko ezisemgangathweni (okt, i-1 ° C kunye ne-1,7918 g / cm³. Kubalulekile ukuba uqaphele ukuba eli xabiso liyahluka ngeqondo lobushushu kunye noxinzelelo, ke ukuxinana kungahluka kancinci phantsi kweemeko ezahlukeneyo zokusebenza. Ukuqonda iipropathi ezisisiseko zeMethanol Ukuxinana kunceda ekumiseni ngokuchanekileyo kunye nokulawula ngokuphendula kwiinkqubo zekhemikhali.
Izinto ezichaphazela i-methanol dexince
Iziphumo zobushushu kwi-methanol dexince
Iqondo lokushisa yenye yezona zinto zibalulekileyo ezichaphazela ubuxilongo be-methanol. Njengoko iqondo lobushushu liyanda, amandla e-kinetic ye-methanol molekyum anyuka kwaye umgama phakathi kweemolekyuli unyuka, okukhokelela ekunciphiseni komntu. Umzekelo, kubushushu begumbi (i-20 ° C), i-methanol inexilongo le-0.7918 g / cm³, enqumlayo kwi-0.762 g / cmł xa iqondo lobushushu lonyuke linga kube yi-60 ° C. Olu xinzelelo lokuxhomekeka kufuneka luthathelwe ingqalelo kwizicelo ezisebenzayo, ngakumbi apho imisebenzi yobushushu isebenza okanye apho ivolumu ye-methanol kufuneka ilinganiswe ngokuchanekileyo.
Iziphumo zoxinzelelo kwi-Methanol Density
Nangona isiphumo soxinzelelo ekuxineni lolwelo luhlala lincinci, kwimo yoxinzelelo oluphezulu kule nto ayinakutyeshelwa. Ukomeleza koxinzelelo kunyanzela umgama phakathi kweemolekyuli ukuze kunciphe, ngaloo ndlela kukhulisa ububi bukaMethanol. Ngolwelo olunje nge-methanol, utshintsho kuxinzelelo ngenxa yoxinzelelo luhlala lubhekiswa kunotshintsho kubushushu. Ke ngoko, isiphumo soxinzelelo kwi-methanol inokuthathwa njengeziseko zemeko eziqhelekileyo, kodwa le nto isafuna ukuba ithathelwe ingqalelo kwizixhobo eziphezulu zekhemikhali.
Iindlela zokulinganisa zeMethanol Derity
Indlela yokulinganisa elebhu
Elabhoratri, ukuxinana nge-methanol kuhlala kulinganiswe usebenzisa ibhotile yesixhobo okanye i-densteometer. Indlela ethile yebhotile yomoya yindlela yokulinganisa uClassicals, apho i-dexinety ibalwa ngokulinganisa ubunzima obuthile bobubele buzaliswe lulwelo. I-devenaometer sisixhobo esilinganisa ngokuthe ngqo ubuninzi bobuninzi kwaye ichonge ukuxinana kolwelo ngomgaqo we-buoyey ye-buoyey ye-buoyey ye-buoyey ye-buoyey yeedada. Zombini iindlela zinezibonelelo zayo kunye nezinto eziluncedo, ezazingaphambili zichanekile kakhulu kodwa i-cumprmeme ukuba isebenze, ilula ilula ukuba isebenze kodwa ifuna ukukhetha okuphezulu kwesixhobo.
Umlinganiso wemizi-mveliso kwi-intanethi
Kwimveliso yemizi-mveliso, ukubek'esweni okwenyani kwe-methanol ukuxinana kubalulekile kulawulo lwenkqubo. Izixhobo ezisetyenziswayo ezisetyenziswayo zisetyenziswa kwi-intanethi I-tube ye-tube i-tube dennstoometers ichonge ukuxinana ngokulinganisa i-cube ye-cube, ngelixa i-uxinamonic densitomometers ifumana uxinano kwi-velosonic amaza e-Ultrasonic amaza ahamba ngolwelo. Ezi zixhobo zibonelela ngedatha yexesha lokwenyani ngexesha lenkqubo yemveliso yokuqinisekisa ukuba iimeko zokusebenza zikwimida egqibeleleyo.
Ukuxinana kweMethanol kwishishini leekhemikhali
Ukuzimisela ngokuchanekileyo kunye nolawulo lwe-methanol dembaity lunoluhlu olubanzi lwezicelo kwishishini lekhemikhali. Umzekelo, ekuphenduleni malunga nobunjineli, uxinzelelo yiparameter ephambili kwi-accounting ye-Akhawuntingi kunye namandla. Xa ukugcina nokuhambisa i-methanol, idatha yoxinano inokunceda ekufumaniseni ukuba ubungakanani bokuzaliswa kweetanki zokugcina kunye nokulayishwa kwezithuthi zothutho. Idatha yoxinano inokusetyenziselwa ukubeka esweni ubunyulu beMethanol, njengoko ubukho bokungcola bahlala bekhokelela kumahluko ongaqhelekanga.
Isishwankathelo
Ukuxinana kweMethanol yiparamitha ephambili kwishishini lekhemikhali, echaphazela iinkalo ezininzi zomsebenzi kunye noyilo. Ngokuqonda iipropathi zayo, iindlela zokulinganisa kunye nokuphembelela, iingcali zecandelo lekhemikhali ziyakwazi ukulawula inkqubo yokuvelisa, zisenza ukuba kusetyenziswe izixhobo kunye nokusebenza ngokufanelekileyo. Ukulungelelanisa ukuqonda nokusebenzisa uxinzelelo lwe-methanol phantsi kweemeko ezahlukeneyo yindlela ebalulekileyo yokuphucula ukusebenza kwamashishini.
