Methanol kachulukidwe wofotokozedwa: Makhalidwe, muyeso ndi zinthu zomwe zikukhudza
Mwachidule kwa methanol kachulukidwe
Methanol (mtundu wa mankhwala: Ch₃oh) ndi mankhwala ofunikira mankhwala osamera, ndipo kachulukidwe wake ndi gawo lofunikira kwambiri lomwe limapangitsa ubale wake. Kudziwa ndi kumvetsetsa kwa kachulukidwe kwa methanol ndikofunikira pakupanga mafakitale, kugwiritsa ntchito mankhwala ndi mayendedwe. Nthawi zambiri, kachulukidwe ndi chinthu china chopangidwa ndi chinthu ndipo chimagwirizana kwambiri ndi mikhalidwe monga kutentha ndi kupanikizika. Munkhaniyi, tikambirana mwatsatanetsatane zomwe zimapangitsa kuti methanol kachulukidwe, njira zake zomwe zimawonjezera njira ndi zinthu zomwe zikuwakhudza, kukuthandizani kumvetsetsa bwino gawo lofunikira.
Zoyambira za methanol kachulukidwe
Kuchulukitsa kwa methanol nthawi zambiri kumafotokozedwa malinga ndi voliyumu iliyonse pa unit misa ya methanol, ndipo, 20 ° C ndi 1.7118 g / cm³. Ndikofunikira kudziwa kuti mtengo uwu umasiyanasiyana ndi kutentha ndi kukakamizidwa, kotero kachulukidwe kamasiyana mosiyanasiyana mosiyanasiyana. Kuzindikira zofunikira za methanol kachulukidwe kumathandizira pakuwongolera kolondola ndi kuwongolera mu mankhwala.
Zinthu zomwe zikukhudza TEENTE
Zotsatira za kutentha pa methanol kachulukidwe
Kutentha ndi chimodzi mwazinthu zofunikira kwambiri zomwe zimakhudza kachulukidwe wa methanol. Pamene kutentha kumawonjezeka, mphamvu ya kinatic ya matrohanol mamolekyulu amawonjezeka ndipo mtunda pakati pa mamolekyules amawonjezeka, zomwe zimapangitsa kuchepa kwa kachulukidwe. Mwachitsanzo, kutentha kwa chipinda (20 ° C), Methanol ali ndi kachulukidwe ka 0,7918 g / cm³, komwe kumachepetsa pafupifupi 0,762 g / cm ° C Gute C Gle. Kukhazikika kwa kutentha kumeneku kumayenera kuganiziridwa mu akaunti yothandiza, makamaka kumene ntchito kutentha kwambiri kumakhudzidwa kapena komwe kuchuluka kwa methanol ayenera kuyezedwa molondola.
Mphamvu ya kukakamiza pa menanol kachulukidwe
Ngakhale zimapangitsa kuti kupanikizika kwa madzimadzi nthawi zambiri kumakhala kochepa, m'malo okwera kwambiri chinthu sichinganyalanyazidwe. Kuchulukitsa kupanikizika kumapangitsa mtunda pakati pa mamolekyulu kuti achepetse, potero kuwonjezera kuchuluka kwa methanol. Kwa madzi monga methanol, kusintha kwa kachulukidwe chifukwa cha kukakamizidwa nthawi zambiri kumatchulidwa kuposa kusintha kwa kutentha. Chifukwa chake, zomwe zimapangitsa kukakamizidwa pa kachulukidwe ka methanol zitha kuganiziridwanso zachinyengo pamavuto wamba, koma chinthuchi chikufunikabe kuganiziridwabe zida zapamwamba zamankhwala.
Njira zoyezera za methanol kachulukidwe
Njira yoyesera ya labotale
Mu labotale, methanol kachulukidwe nthawi zambiri umayesedwa pogwiritsa ntchito botolo linalake kapena densitometer. Njira yokola yokoka ndi njira yopumira kwambiri, pomwe kachulukidwe kamawerengedwa ndikuyeza unyinji wa botolo lokola lodzaza ndi madzi. Donnitometer ndi chida chomwe chimayesa kachulukidwe ka madzi ndikupanga kachulukidwe ka madzi kudzera munjira yoyandama. Njira zonse zili ndi zabwino zake komanso zovuta zake, zomwe kale anali wolondola kwambiri koma wovuta kugwira ntchito, zotsalazo ndizosavuta kugwira ntchito koma zimafunikira utsogoleri wambiri.
Muyeso wa mafakitale
Popanga mafakitale, kuwunika kwanthawi yeniyeni kwa kachulukidwe ka methanol ndikofunikira kuti muyendetse ulamuliro. Zithunzi zofananira za mzere pa intaneti zimaphatikizanso mphamvu zowoneka bwino za chubu ndi ma punititoments. Kugwedezeka kwa chubu cha chubu kudziwa kachulukidwe kanthawi kochepa kwa madzi mkatikati, pomwe akupanga vanitoments amachokera ku vensikity kuchokera ku velocity ya ma duceloshic amayenda kudzera mu madzi. Zipangizozi zimapereka chidziwitso chenicheni pakupanga njira zopangira kuti zitsimikizire kuti zinthu zothandizira sizimagwirizana.
Methanol kachulukidwe kaampani
Kutsimikiza ndi kuwongolera koyenera kwa methanol kachulukidwe kumakhala ntchito zingapo pamakampani opanga mankhwala. Mwachitsanzo. Mukamasungira ndi kunyamula methanol, deta ya kapazi mphamvu imatha kuthandiza kudziwa kuchuluka kwa akasinja osungirako komanso kunyamula magalimoto oyendera. Zolemba zochulukitsa zimatha kugwiritsidwanso ntchito kuwunika kuyera kwa methanol, chifukwa kupezeka kwa zosayera nthawi zambiri kumapangitsa kuti mitundu yosiyanasiyana ikhale yopanda tanthauzo.
Chidule
Methanol kachulukidwe ndi gawo lofunikira mu malonda opanga mankhwala, likukhudza mbali zingapo zogwirira ntchito ndi kapangidwe. Mwa kumvetsetsa momwe alili, muyeso wa njira ndi zidwi zochititsa chidwi, mapu akatswiri opanga mankhwala amatha kuwongolera njira zopangira, kutsimikizira kuti chitetezo ndi champhamvu. Kugwiritsa ntchito kumvetsetsa ndi kugwiritsa ntchito kachulukidwe kwa methanol pansi m'njira zosiyanasiyana ndi njira yofunika kwambiri yothandizira mafakitale.
