Ethylene okusayidindi mankhwala achilengedwe okhala ndi njira ya mankhwalaC2H4ONdi poizoni woyambitsa khansa ndipo amagwiritsidwa ntchito popanga mankhwala ophera bowa. Ethylene oxide imatha kuyaka komanso kuphulika, ndipo sikophweka kunyamula pamtunda wautali, kotero imakhala yoopsa m'madera osiyanasiyana.
Kodi ndiyenera kusamala ndi chiyani ndikasunga ethylene oxide?
Ethylene okusayidiimasungidwa m'matangi ozungulira, ndipo matangi ozungulira amasungidwa mufiriji, ndipo kutentha kosungirako kumakhala kochepera madigiri 10. Popeza mphete B ili ndi malo otsika kwambiri owunikira komanso imadziphulika yokha, ndi bwino kuisunga mufiriji.
1. Thanki yopingasa (chotengera choponderezera), Vg=100m3, choziziritsira chomangidwa mkati (jekete kapena mtundu wa coil wamkati, wokhala ndi madzi ozizira), chotsekedwa ndi nayitrogeni. Choteteza ndi polyurethane block
2. Kupanikizika kokonzekera kumatenga mphamvu yapamwamba kwambiri ya dongosolo loperekera nayitrogeni (EOKusunga ndi kutseka kwa nayitrogeni sikukhudza kuyera kwake, ndipo kungachepetsenso bwino chiopsezo cha kuphulika).
3. Choziziritsira chomangidwa mkati: Ndi chubu cholumikizira (kapena pakati) cha chosinthira kutentha cha U-tube. Chikukonzekera kukhala chosinthika, chomwe chili chosavuta kukonza ndikusintha.
4. Chophimba choziziritsira chomwe chili mkati mwake chili chokhazikika: chitoliro choziziritsira cha serpentine chomwe chili mkati mwa thanki yosungiramo zinthu sichingachotsedwe.
5. Choziziritsira: palibe kusiyana, zonse ndi madzi ozizira (kuchuluka kwa yankho lamadzi la ethylene glycol).
