Puas yog propargyl cawv muaj tshuaj lom heev?Txoj kev loj hlob ntawm kev lag luam cawv propargyl yog dab tsi?Propargyl cawv, hu ua 2-propargyl-1-cawv, 3-hydroxymethyl acetylene thiab ethynyl methanol, nrog rau cov mis mos C3H4O thiab molecular hnyav ntawm 56.07.Nws yog cov kua uas tsis muaj xim pob tshab nrog cov ntxhiab tsw ntawm nplooj.Nws yog ib qho yooj yim kom tig daj tom qab khaws cia ntev, tshwj xeeb tshaj yog thaum raug teeb.Nws yog cov kua dej uas muaj nplaim taws, yooj yim soluble hauv dej, cawv thiab ether.Nws tuaj yeem siv los ua xeb tshem tawm, tshuaj lom neeg nruab nrab, corrosion inhibitor, hnyav, stabilizer, thiab lwm yam.
Txoj kev loj hlob thiab Kev Tshawb Fawb Kev Tshawb Fawb ntawm kev lag luam cawv propargyl hauv Suav teb
Propargyl cawv yog ib qho tseem ceeb ntawm cov khoom siv raw, uas yog siv dav hauv kev lag luam tshuaj, tshuaj lom neeg kev lag luam, electroplating, tshuaj tua kab, hlau thiab roj siv, thiab lwm yam nrog rau cov nqi ntxiv, nws feem ntau yog npaj los ntawm cov tshuaj tiv thaiv formaldehyde thiab acetylene.
Hauv Suav teb, propargyl cawv feem ntau yog siv los ua cov khoom siv tshuaj raw khoom fosfomycin sodium, fosfomycin calcium, SULFAPYRIDINE thiab tshuaj tua kab chlorhexidine, suav txog li 60% ntawm tag nrho;Kwv yees li 17% ntawm cov nickel leveling cov neeg ua hauj lwm ceev ceev thiab cov brighteners yog siv rau electroplating (qhov ntev-ua yeeb yam leveling tus neeg saib xyuas thiab brightener yog 1,4-butynediol, tab sis lub brightness tsis muaj zog);Roj exploitation suav txog li 10%;Kev lag luam metallurgical suav txog li 8%;Lwm qhov kev lag luam suav txog li 5%.
Nyob rau hauv 2019, Tuam Tshoj qhov kev thov rau propargyl cawv yog 5088.9 tons, nrog rau ib lub xyoo nce ntawm 7.3%;Xyoo 2020, Tuam Tshoj qhov kev thov rau propargyl cawv yog 5353.5 tons, nrog rau ib xyoos ib zaug nce ntawm 5.2%;Nyob rau hauv 2021, qhov kev thov rau propargyl cawv nyob rau hauv Tuam Tshoj yog 5717.8 tons, nrog rau ib lub xyoo nce ntawm 6.8%.
BASF yog lub chaw tsim khoom tseem ceeb ntawm propargyl cawv nyob rau hauv txawv teb chaws, thiab lub tuam txhab tseem ceeb hauv tsev muaj xws li Shandong dong'a fengle tshuaj, Henan Haiyuan nplua tshuaj, Henan zog thiab tshuaj pab pawg Hebi Coal Chemical, thiab lwm yam. Tam sim no, loj-scale 1,4 -butanediol cov tuam txhab tsim khoom muaj qee qhov txiaj ntsig zoo yog tias lawv siv cov khoom siv qis alkynaldehyde los ntawm cov khoom lag luam rov qab los tsim cov cawv propargyl.
