MF C8F18
Ko te ira rewa o te perfluorooctane (C8F18) he -25℃ me te ira kohua he 103℃. Kāore e mura, kāore e paitini, he tino pumau te matū, ā, kāore he tae. Kāore e wairewa te perfluorooctane i roto i te wai, te etanoru, te waikawa acetic me te formaldehyde, engari ka taea te wairewa ki roto i te ethyl ether, te acetone, te dichloromethane, te chloroform me te fluorochloroalkane. He iti te kukū o te mata o te perfluorooctane, he kaha teitei ki te dielectric, he ātete wera pai rawa atu, ā, he pāmahana pirau neke atu i te 800℃. Ka taea e te perfluorooctane te wairewa i te nui o te hāora me te hauhā waro, ā, ka taea te whakamahi me ētahi atu matū fluorocarbon hei toto horihori me te wai tiaki okana in vitro.
I roto i te rongoā, ka taea te whakamahi i te perfluorooctane me ētahi atu fluorocarbons hei toto horihori me te otinga tiaki okana in vitro.
Ka taea te whakamahi i te perfluorooctane hei wai whakamatao me te wai ārai i roto i ngā taputapu hiko maha.
Hei tāpiritanga, ka taea hoki te whakamahi i te perfluorooctane hei wai waipēhi me te hinu whakahinuhinu mō ngā mīhini tino tika, te kaihoko horoi, te reo whakawhiti wera, te wai wehewehe hiri taputapu, te reo tauhohenga matū, te whakarewa rānei.
Tākai:
Ko ngā whakaritenga mō te takai perfluorooctane e whai ake nei: 25 karamu, 500 karamu te takai pounamu kirihou, 5 kirokaramu te takai oko kirihou, 25 kirokaramu te takai maitai me te 50 kirokaramu te takai oko kirihou. Ka taea te whakarite i ngā whakaritenga mō te takai kia rite ki ngā hiahia o te kaiwhakamahi.
Me rongoa te perfluorooctane ki roto i tētahi whare putunga hauhautanga, ā, he tawhiti atu i te ahi me te wera. Me rongoa motuhake me ngā waikura, ngā matū e taea te kai me ngā konganuku kawakore.
