Ubucucike bwa Methanol bwasobanuwe: Ibiranga, gupima nibintu bigira ingaruka
Incamake yubucucike bwa Methanol
Methanol (formulaire ya chimique: CH₃OH) nigikoresho cyingenzi cyimiti, kandi ubucucike bwacyo nikintu cyingenzi kigereranya umubano wacyo. Ubumenyi no gusobanukirwa ubwinshi bwa methanol nibyingenzi mubikorwa byinganda, gukoresha imiti no gutwara abantu. Mubisanzwe, ubucucike ni umutungo wihariye wibintu kandi bifitanye isano rya bugufi nubushyuhe nubushyuhe. Muri iki kiganiro, tuzaganira ku buryo burambuye imiterere yubucucike bwa methanol, uburyo bwo gupima nimpamvu zibigiraho ingaruka, kugirango bigufashe kumva neza iki kintu cyingenzi.
Ibintu shingiro byubucucike bwa methanol
Ubucucike bwa methanol busanzwe bugaragazwa ukurikije ingano kuri buri gice cya methanol, kandi mubihe bisanzwe (ni ukuvuga 20 ° C na atm 1), ubucucike bwa methanol bugera kuri 0,7918 g / cm³. Ni ngombwa kumenya ko ako gaciro gatandukana nubushyuhe nigitutu, bityo ubucucike bushobora gutandukana gato mubikorwa bitandukanye. Gusobanukirwa nibintu byibanze byubucucike bwa methanol bifasha mugupima neza no kugenzura imikorere mubikorwa bya shimi.
Ibintu bigira ingaruka kuri methanol
Ingaruka yubushyuhe kuri methanol
Ubushyuhe ni kimwe mu bintu by'ingenzi bigira ingaruka ku bucucike bwa methanol. Mugihe ubushyuhe bwiyongera, ingufu za kinetic ya molekile ya methanol iriyongera kandi intera iri hagati ya molekile ikiyongera, bigatuma igabanuka ryubwinshi. Kurugero, mubushyuhe bwicyumba (20 ° C), methanol ifite ubucucike bwa 0,7918 g / cm³, bikagabanuka kugera kuri 0,762 g / cm³ mugihe ubushyuhe bwiyongereye kugera kuri 60 ° C. Ubu bushyuhe bushingiye ku bushyuhe bugomba kwitabwaho mubikorwa bifatika, cyane cyane aho ubushyuhe bwo hejuru burimo cyangwa aho ingano ya methanol igomba gupimwa neza.
Ingaruka z'umuvuduko kuri methanol
Nubwo ingaruka zumuvuduko mubucucike bwamazi ubusanzwe ari nto, mubidukikije byumuvuduko mwinshi iki kintu ntigishobora kwirengagizwa. Kwiyongera k'umuvuduko bihatira intera iri hagati ya molekile kugabanuka, bityo bikongerera gato ubwinshi bwa methanol. Kubisukari nka methanol, impinduka mubucucike bitewe numuvuduko mubisanzwe ntabwo bigaragara cyane kuruta ihinduka ryubushyuhe. Kubwibyo, ingaruka zumuvuduko wubucucike bwa methanol zirashobora gufatwa nkizakabiri mugihe gisanzwe gikora, ariko iki kintu kiracyakenewe gusuzumwa mubikoresho byimiti yumuvuduko ukabije.
Uburyo bwo gupima ubwinshi bwa methanol
Uburyo bwo gupima laboratoire
Muri laboratoire, ubucucike bwa methanol busanzwe bupimwa hifashishijwe icupa ryihariye rya gravit cyangwa densitometero. Uburyo bwihariye bwamacupa ya gravitike nuburyo bwa kera bwo gupima ubucucike, aho ubucucike bubarwa mugupima ubwinshi bwicupa ryihariye ryuzuye ryuzuye amazi. Densitometero ni igikoresho gipima mu buryo butaziguye ubucucike bw’amazi kandi kikagena ubwinshi bw’amazi binyuze mu ihame ryo kuguruka kureremba. Ubwo buryo bwombi bufite ibyiza n'ibibi, ibyambere birasobanutse neza ariko biragoye gukora, ibyanyuma biroroshye gukora ariko bisaba kalibrasi yo hejuru yibikoresho.
Inganda kumurongo
Mu musaruro w’inganda, kugenzura igihe nyacyo cya methanol ni ngombwa kugirango igenzurwe. Bikunze gukoreshwa kumurongo wo gupima uburinganire burimo vibrating tube densitometero na ultrasonic densitometero. Vibrating tube densitometero igena ubucucike mugupima inshuro ya resonant yumubiri wamazi imbere yinyeganyeza, mugihe ultrasonic densitometero ikura ubucucike buturuka kumuvuduko wumuraba wa ultrasonic unyura mumazi. Ibi bikoresho bitanga amakuru nyayo mugihe cyibikorwa byo gukora kugirango tumenye neza ko imikorere ikora iri mumipaka myiza.
Ubucucike bwa Methanol mu nganda zikora imiti
Kugena neza no kugenzura ubucucike bwa methanol bifite uburyo bwinshi bwo gukoresha mu nganda zikora imiti. Kurugero, mubikorwa byubushakashatsi, ubucucike nibintu byingenzi mubucungamutungo no kubara ingufu. Iyo kubika no gutwara methanol, amakuru yubucucike arashobora gufasha kumenya ubushobozi bwo kuzuza ibigega byo kubika no gupakira ibinyabiziga bitwara. Ubucucike burashobora kandi gukoreshwa mugukurikirana isuku ya methanol, kuko kuba hariho umwanda akenshi biganisha ku guhinduka kudasanzwe mubucucike.
Incamake
Ubucucike bwa Methanol ni ikintu cy'ingenzi mu nganda zikora imiti, bigira ingaruka ku mikorere itandukanye. Mugusobanukirwa imiterere yabyo, uburyo bwo gupima nibintu bigira ingaruka, abakora inganda zimiti barashobora kugenzura neza imikorere yumusaruro, kunoza imikoreshereze yumutungo no kurinda umutekano nibikorwa neza. Gushyira mu gaciro gusobanukirwa no gukoresha ubwinshi bwa methanol mubihe bitandukanye ninzira yingenzi yo kunoza imikorere yinganda.
