Ua raws li cov kev xav ntawm "kev daws teeb meem zoo nkauj, peb ib txwm muaj kev ntseeg siab thiab muaj peev xwm ua tiav kev hloov pauv thiab kev xav tau kev pab tsis tu ncua thiab kev xav tau.
Sticking rau koj txoj kev xav ntawm "tsim cov kev daws teeb meem ntawm cov kev daws teeb meem sab saum toj thiab ua rau cov neeg los ntawm thoob plaws ntiaj teb", peb ib txwm teeb tsa lub siab xav tau nrog rauTuam Tshoj acetylene roj thiab C2h2 roj, Lawv ruaj ruaj ua qauv thiab kev txhawb nqa zoo thoob plaws ntiaj teb. Tsis muaj ib qho xwm txheej ploj mus nyob rau ib lub sijhawm tseem ceeb hauv lub sijhawm luv luv, nws yog ib qho yuav tsum rau koj tus kheej ntawm cov zoo heev. Coj los ntawm lub hauv paus ntsiab lus ntawm kev ua siab ceev, kev ua tau zoo, Union thiab kev tsim kho tshiab. Lub lag luam ua rau muaj kev sib zog zoo nthuav dav nws txoj kev lag luam thoob ntiaj teb, nce nws txoj kev lag luam. rofit thiab txhim kho nws cov nplai xa tawm. Peb muaj kev ntseeg siab tias peb yuav muaj lub siab xav thiab faib thoob plaws lub ntiaj teb nyob rau hauv lub xyoo dhau los.

Acetylene, molecular mis c2h2, feem ntau yog hu ua cua courula lossis calcium carbide roj, yog tus tswv cuab tsawg tshaj plaws ntawm Alkyne sib txuas. Acetylene yog ib qho muaj xim tsis muaj kob, cov roj ntsha me me thiab cov kev ua kom tsis muaj zog thiab kev tawm tsam oxidation raws li qhov kub thiab kub. Nws yog me ntsis soluble hauv dej, soluble hauv ethanol, benzene, thiab acetone. Ntshiab acetylene tsis muaj ntxhiab tsw muaj ntxhiab, tab sis industrylene muaj qhov tsis hnov tsw ntawm qej vim tias nws muaj impurities xws li hydrogen sulfide thiab phosphine. Ntshiab acetylene yog ib qho tsis muaj kob thiab muaj ntxhiab tsw qab roj. Nws yuav tawg ua nruj ua ke hauv cov kua thiab khoom hauv lub xeev lossis hauv lub xeev gaseous thiab qee yam siab. Yam khoom xws li cua sov, kev co, thiab hluav taws xob hluav taws xob tuaj yeem ua rau tawg, yog li nws tsis tuaj yeem ua rau lub siab liquefied. Cia lossis tsheb thauj mus los. Ntawm 15 ° C thiab 1.5MPA, lub solubility hauv acetone yog qhov solubilene siab heev, muaj acetylene yaj tau acetone, tseem hu ua actolved acetylene. Yog li ntawd, hauv kev lag luam, hauv cov thooj voos kheej kheej uas muaj cov ntaub ntawv asbestos xws li asbestos, acetylene raug nias rau cov khoom siv ntxeem tom qab kev khaws cia thiab tsheb thauj mus los. Acetylene roj tuaj yeem tsim cov siab kub thaum hlawv. Qhov kub ntawm cov nplaim taws oxyacetylene tuaj yeem ncav cuag 3200 ℃. Feem ntau nws siv rau cov hlau txiav xws li cov qauv nkoj thiab cov qauv hlau; Nws yog siv rau cov synthic synthesis (ua acetaldehyde, acticetic acid, thiab cov tshuaj siv hluavtaws, hluavtaws nruab nrab thiab tshuaj lom neeg acetylene lossis divinyl acetylene lossis divinyl acetylene lossis divinyl acetylene los yog divinyl acetylene; Siv los tsim cov roj teeb xws li kev ntsuas roj ntsuas roj hloov roj. High-purity acetylene roj yog siv rau atomic nqus thiab lwm yam twj paj nruag. Cov ntim ntim ntawm cov acetylene feem ntau yog yaj nyob rau hauv cov kuab tshuaj thiab cov ntaub ntawv ntxeem tau thiab sau rau hauv hlau thooj voos kheej kheej. Khaws rau hauv qhov chaw txias, tshuab ua kom muaj zog. Tseg deb ntawm hluav taws thiab cov khoom cua sov. Qhov kub yuav tsum tsis pub tshaj 30 ° C. Nws yuav tsum tau muab cais cais los ntawm oxidants, acids, thiab halogens, thiab zam kev sib xyaw. Siv tawg-pov thawj teeb pom kev zoo thiab cov chaw tua hluav taws xob. Nws yog txwv tsis pub siv cov khoom siv txhua yam thiab cov cuab yeej uas yog nquag ua rau txim taws. Cov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv thaum muaj xwm ceev.
①cutting thiab vuam hlau:
Thaum acetylene hlawv, nws tuaj yeem tsim cov siab kub. Qhov kub ntawm cov nplaim taws oxyacetylene tuaj yeem ncav cuag 3200 ℃, uas yog siv rau kev txiav thiab vuam hlau.
②basic tshuaj rwb khoom siv:
Acetylene yog cov khoom siv raw ua acetylene rau kev tsim cov acetaldehyde, acetic acid, benthetic roj hmab, thiab hluavtaws fibers.
③ Sim
Cov Purity Purity Acetylene tuaj yeem siv qee qhov kev sim.
