LUB keeb kwm ntawm FK 5 1 12 Tus neeg saib xyuas huv
FK 5 1 12 Tus neeg saib xyuas huv, tseem hu ua Perfluorohexanone, nrog cov tshuaj formula ntawm CF3CF2COCF(CF3)2, tam sim no muaj kev tshawb fawb qhia tau hais tias nyob rau hauv 1970s, cov kws tshawb fawb nyob rau hauv lub qub Soviet Union tau tshaj tawm cov synthesis technology ntawm perfluorohexanone, tab sis nws tsis tau muab tso rau hauv kev tsim khoom loj; nyob rau xyoo 1980s, Shanghai San Ai Fu New Materials Co., Ltd. kuj tau txais ib qho me me ntawm perfluorohexanone siv los ua cov kuab tshuaj thaum lub sij hawm tsim cov perfluoro-n-propyl vinyl ether.
Tom qab ntawd, nrog rau kev siv cov cai tiv thaiv ib puag ncig, halon hluav taws tua hluav taws raug tshem tawm. Xyoo 2001, Lub Tuam Txhab US 3M tau tsim cov tshuaj tua hluav taws tua hluav taws perfluorohexanone los ua ib qho kev hloov halon, nrog rau lub npe lag luam Novec1230, uas tau txais kev pom zoo.
Perfluorohexanone yog xim tsis muaj xim, tsis muaj ntxhiab, pob tshab kua ntawm chav tsev kub thiab yooj yim vaporized. Nws qhov kub ntawm evaporation yog 1/25 ntawm cov dej. Cov cuab yeej no tso cai rau nws ua tiav cov txiaj ntsig ntawm kev tua hluav taws los ntawm kev nqus cua sov los ntawm vaporization. Txij li thaum lub siab ntawm perfluorohexanone nyob rau hauv lub tank cia yog tsawg, nws yog heev yooj yim mus thauj.

Nws yog ib qho tsim nyog sau cia tias perfluorohexanone tsis muaj cov tshuaj tiv thaiv zoo rau cov khoom siv roj hmab thiab cov yas sealing, xws li chloroprene roj hmab, butyl roj hmab, ethylene propylene roj hmab, thiab lwm yam, tsis muaj corrosive rau cov hlau uas nquag siv, thiab tsis ua rau cov khoom siv hluav taws xob puas. thiab circuits. Nws yog non-conductive thiab tsis tawm ib qho seem tom qab tso tawm, yog li nws tsim nyog rau kev tiv thaiv precision thiab cov khoom siv hluav taws xob muaj txiaj ntsig.
Hais txog kev tua hluav taws, kev siv cov tshuaj perfluorohexanone yog 4% ~ 6%, uas zoo ib yam li Halon 1301, qis dua lwm cov hluav taws tua hluav taws, thiab muaj kev ua haujlwm siab.
Piv nrog rau lwm cov tshuaj tua hluav taws, qhov zoo tshaj plaws ntawm perfluorohexanone yog nws cov phooj ywg ib puag ncig. Lub peev xwm ozone depletion (ODP) ntawm perfluorohexanone tua hluav taws yog 0, uas txhais tau hais tias nws tsis muaj kev puas tsuaj rau ozone; nyob rau hauv cov nqe lus ntawm lub ntiaj teb no warming nyhuv. Lub ntiaj teb ua kom sov muaj peev xwm (GWP) ntawm perfluorohexanone tsuas yog 1, uas yog 1/3500 ntawm heptafluoropropane, thiab nws lub sijhawm nyob hauv huab cua yog 5 hnub, ua rau nws yog ib qho ntsuab thiab ib puag ncig tus phooj ywg refrigerant.
Hais txog kev nyab xeeb, qhov kev nyab xeeb kev nyab xeeb ntawm perfluorohexanone yog siab li 67 ~ 150%, uas txhais tau hais tias nws muaj kev nyab xeeb dua rau tib neeg lub cev thaum siv. Nws tau pom zoo los ntawm US Environmental Protection Agency rau siv nyob rau hauv cov chaw uas muaj neeg nyob.
