Vim li cas cov calcium carbide txwv?
Calcium carbide yogtxwv lossis txwv nyob hauv ntau lub tebchaws, tshwj xeeb rau kev siv hauv cov txiv hmab txiv ntoo cuav ripening, vim cov laj thawj hauv qab no:
Kev Noj Qab Haus Huv:Cov roj ntsha-qhab nia-cov carbide feem ntau muaj cov pa roj ntsha thiab phosphoric.}} {1}.. cov teeb meem raum, thiab feem cuam tshuam cancer nrog ntev ntev ua .
Unreen ripening:Artificial ripening nrog calcbide feem ntau ua rau uneven ripening ntawm cov txiv hmab txiv ntoo, cuam tshuam rau qee qhov chaw uas lwm tus nyob twj ywm.
Kev Nyab Xeeb Kev Nyab Xeeb Rau Cov Neeg Ua Haujlwm:Kev sib chwv ncaj qha nrog cov calcium carbide yog cov kev puas tsuaj rau cov pa taws, ua rau tawv nqaij {{0} {{0} Qhov kev pheej hmoo ntawm cov xwm txheej thaum tuav.
Thaum txwv rau cov txiv hmab txiv ntoo ripening nyob rau ntau qhov chaw, calcium carbide tseem muaj caiKev Siv Khoom Siv, uas yog vim li cas thiaj li ua tiav lub ntiaj teb txiav npluav ntawm nws cov kev tsim khoom thiab siv rau txhua lub hom phiaj tsis yog ib txwm ua kom.
Dab tsi yog calcium carbide siv rau?
Calcium carbide (CAC2) muaj ntau yam kev lag luam siv, feem ntau vim nws cov tshuaj tiv thaiv dej ua pa roj av:
Kev tsim cov acetylene:Qhov no yog qhov tseem ceeb tshaj plaws . acetylene yog siv los ua cov roj av (oxyacetylene charding), thiab ua cov tshuaj pleev xim rau hauv cov tshuaj, suav nrog polyvinyl chloride (PVC) {1}.
Kev tsim cov calcium cyanamide:Calcium carbide reacts nrog nitrogen ntawm qhov kub thiab txias los tsim calcium cyanamide (CACNN2), uas yog siv los ua chiv {}}
Steelmaking:Nws yog siv los ua tus neeg saib xyuas desulfurizing rau cov hlau, npua hlau, thiab hlau. Kuv tseem tuaj yeem ua kom cov roj ntsha ua kua hlau thiab ua kom muaj zog deoxidizer nyob rau hauv cov chaw kho kom zoo {}}
Carbide Teeb:Keeb kwm, nws tau siv nyob rau hauv carbide teeb txoj hauj lwm {}}}}}}}} Cov no tau siv rau hauv kev sib khuav thiab tsheb thaum ntxov.
Lwm Yam Siv:Nws muaj cov ntawv thov me hauv cov cannons ua si, xyoob cannons, kev txiav txim siab cov av noo noo, thiab ua cov tshuaj pleev li mole {}}
Vim li cas koj tsis tuaj yeem kov calcium carbide?
Koj yuav tsum tsis txhob kov calcium carbide vim tiasnws reacts txaus ntshai nrog ya raws, suav nrog cov dej vapor hauv huab cua thiab hws ntawm koj cov tawv nqaij .15Qhov tshuaj tiv thaiv no tsim:
Flammene Acetylene Roj:Acetylene yog cov nplaim taws heev thiab tuaj yeem yooj yim zes, ua rau hluav taws lossis tawg .
Thaum Tshav Kub Kub:Cov kev tawm tsam yog exothermic, lub ntsiab lus nws tshaj tawm kub, uas tuaj yeem ua rau hlawv .
Corrosive calcium hydroxide:Calcium hydroxide (slaked txiv qaub) yog alkaline thiab tuaj yeem ua irritate lossis hlawv cov tawv nqaij, ob lub qhov muag, thiab mucous membranes .
Yuav muaj dab tsi tshwm sim thaum calcium carbide yog tov nrog dej?
Thaum Calcium Carbide (CAC2) yog tov nrog dej (H2 o), ib qho kev tawm tsam hnyav tshwm sim, kev tsim khoomAcetylene roj(C2 H2) thiabcalcium hydroxide(Ca (Oh) 2), nrog rau kev tso tawm thaum tshav kub kub:
CAC2 (s) +2 h2 o (l) → C2 H2 (G) + CA (OH) 2 (AQ) 2 (AQ)
Cov txiaj ntsig tseem ceeb yog:
Kev tsim cov roj tawg:Acetylene roj yog tsim, uas yog qhov tseem ceeb hluav taws thiab tawg kev phom sij .
Tso tawm thaum tshav kub kub:Cov kev tawm tsam yog exothermic thiab tuaj yeem ua rau cov dej kom npau npau thiab muaj peev xwm zes cov acetylene .
Tsim ntawm ib qho kev ua kom haum:Calcium hydroxide, los yog slaked txiv qaub, yog tsim, uas yog alkaline thiab tuaj yeem ua rau muaj kev txob thiab muaj kev npau taws lossis.
