Kusanthula mwatsatanetsatane kwa kuwira kwa toluene
Toluene ndi wamba organic pawiri ndi osiyanasiyana ntchito mu makampani mankhwala. Kumvetsetsa zakuthupi za toluene, makamaka kuwira kwake, ndikofunikira pakupanga ndikugwiritsa ntchito njira zopangira. M'nkhaniyi, tifufuza mwatsatanetsatane chidziwitso cha kutentha kwa toluene ndikusanthula kufunikira kwake m'makampani ndi zinthu zomwe zimakhudza.
Basic katundu wa toluene ndi kuwira mfundo
Toluene (Toluene) ndi methyl m'malo mwa benzene, ndi mankhwala formula C7H8. Ndi madzi oonekera opanda mtundu komanso fungo lonunkhira bwino. Toluene ali ndi kuwira kwa 110.6 ° C (231.1 ° F), komwe kutentha kwake kumasintha kuchoka kumadzi kukhala gasi. Kuwira kwa toluene n'kofunika kwambiri m'mafakitale chifukwa kumakhudza mwachindunji distillation, kupatukana, ndi njira zina zamankhwala zomwe zimakhudza kusintha kwa gawo.
Malo otentha a toluene pamafakitale
Toluene amagwiritsidwa ntchito ngati zosungunulira, zosungunulira, komanso zapakatikati pakupanga mankhwala mu petrochemical ndi organic synthesis. Toluene ali ndi kuwira kwapamwamba pang'ono kuposa benzene, kotero toluene ndi mankhwala ena ofanana amatha kupatulidwa bwino poyang'anira bwino kutentha pamene zosakaniza ziyenera kulekanitsidwa. Izi ndizofunikira kwambiri popanga zinthu zokhala ndi chiyero chachikulu. Kuwira kwa toluene kumathandizanso kukhathamiritsa kugwiritsa ntchito mphamvu m'mafakitale. Mwachitsanzo, pa distillation, kudziwa kuwira kwa toluene kungathandize kudziwa magawo a zida zotenthetsera, potero kuchepetsa mphamvu zamagetsi.
Zomwe zimakhudza kuwira kwa toluene
Ngakhale kuti toluene imakhala ndi kuwira kwa 110.6 ° C, mchitidwe, kusintha kwa mphamvu yozungulira kungayambitse kusinthasintha kwa malo owira. M'madera otsika kwambiri, kutentha kwa toluene kumachepa, pamene m'madera ovuta kwambiri, kutentha kumawonjezeka. Choncho, zotsatira za kupanikizika pa malo otentha ziyenera kuganiziridwa popanga ndi kugwiritsa ntchito toluene. Malo otentha a toluene amasinthanso akaphatikizidwa ndi mankhwala ena, makamaka pamene azeotropes apangidwa, omwe angakhale ndi mfundo zowira zomwe zimasiyana kwambiri ndi za toluene yoyera.
Malo Owiritsa a Toluene ndi Kugwiritsa Ntchito Motetezeka
M'mafakitale okhudzana ndi toluene, kudziwa ndikumvetsetsa malo otentha a toluene ndikofunikira kuti munthu agwire bwino ntchito. Monga toluene ndi madzi oyaka moto, kutentha kukayandikira kapena kupitirira kuwira kwake, kupanga nthunzi kumawonjezeka kwambiri, zomwe zimawonjezera chiopsezo cha kuphulika ndi moto. Choncho, pogwira toluene, kutentha kuyenera kuyendetsedwa mosamalitsa ndipo njira zoyenera zopewera moto ndi kuphulika ziyenera kuchitidwa kuti zitsimikizire kupanga bwino.
Mapeto
Malo otentha a toluene ndi gawo lofunika kwambiri la thupi lomwe silinganyalanyazidwe mumakampani opanga mankhwala, zomwe sizimangokhudza kupanga bwino, komanso zimakhudzana ndi chitetezo. Kupyolera mu kumvetsetsa mozama za kutentha kwa toluene ndi zomwe zimachititsa, ndondomeko ya mankhwala imatha kupangidwa bwino ndi kukonzedwa bwino kuti ipititse patsogolo khalidwe la mankhwala ndi chitetezo chopanga. M'zochita, kuwongolera molondola kwa kutentha kwa toluene pamodzi ndi kuthamanga, katundu wosakaniza ndi zinthu zina zidzakuthandizani kukwaniritsa ndondomeko yokhazikika komanso yothandiza kwambiri.
