Ethylene waikurahe pūhui waro me te tātai matūC2H4O. He mate pukupuku paitini, ka whakamahia ki te hanga i te mate harore. Ko te Ethylene oxide he muramura me te pahū, a, ehara i te mea ngawari ki te kawe i nga tawhiti tawhiti, na reira he ahua kino a rohe.
He aha taku me aro ki te penapena i te ethylene oxide?
Ethylene waikuraka rongoa i roto i nga taika porowhita, ka whakamataohia nga taika porowhita, ka iti iho i te 10 nga nekehanga te pāmahana rokiroki. I te mea he iti rawa te tohu uira o te mowhiti B me te pahū-whaiaro, he pai ake te penapena i roto i te tio.
1. Taaka Whakapae (puu pehanga), Vg=100m3, whakamatao i roto (koti, momo porowhita o roto ranei, me te wai makariri), hiritia te hauota. Wewete ki te paraka polyurethane
2. Ko te pehanga whakamahere he nui te uara pehanga o te punaha tuku hauota (EOte rokiroki me te hiri hauota e kore e pa ki tona ma, ka taea hoki te whakaiti i te tupono o te pahū).
3. Hangaia-i roto i te mātao: Ko te paihere ngongo (matua ranei) o te U-ngongo whakawhiti wera. Kua whakamaheretia kia waiho hei momo wetewete, he pai mo te tiaki me te whakakapi.
4. Kua whakaritea te porowhita whakamahana i hangaia: e kore e taea te tango i te putorino whakamahana nakahi kei roto i te tank rokiroki.
5. Wae whakamahana: kaore he rereketanga, he wai makariri katoa (he nui o te wairewa wai ethylene glycol).
