Methylene chloride, he matū waro ko te CH2Cl2 te tauira matū, he wai mārama, kāore he tae, he kakara kino rite ki te etera. He paku wairewa ki te wai, te etanoru me te etera. I raro i ngā āhuatanga noa, he whakarewa kore-mura, he iti te ira kohua. Ina nui te kukū o tōna kohu i roto i te hau pāmahana teitei, ka puta he hau whakaranu ngoikore te mura, e whakamahia whānuitia ana hei whakakapi i te etera hinu mura, te etera, me ētahi atu.
Ngā Āhuatanga:Parakoremethylene chlorideKāore he ira mura. Kāore e mura ngā whakarewa kei roto ngā rahinga ōrite o te dichloromethane me te penehīni, te whakarewa naphtha, te toluene rānei. Heoi, ina konatunatua te dichloromethane ki te acetone, ki te wai waipiro methyl Chemicalbook rānei i roto i te ōwehenga 10:1, ka puta he ira mura, he kohu me te hau hei hanga i tētahi ranunga pahū, ko te rohe pahū he 6.2% ~ 15.0% (rahinga).
TONO:
1. Whakamahia mō te whakawhāiti i te witi me te whakamatao i te pouaka whakamātao pēhanga iti me te waeine hauhautanga.
2, Whakamahia hei whakarewa, hei tango, hei kaihoko whakaputa matū.
3, Whakamahia i roto i te umanga hikohiko. He mea whakamahi noa hei horoi hei tango i te hinu.
4, Whakamahia hei rongoā whakangote niho ā-rohe, hei rongoā whakamatao, hei kai tinei ahi, hei horoi i te paninga mata whakarewa me te kai tango hinu.
5, Whakamahia hei takawaenga i roto i te hanganga rauropi.
Tikanga whakarite:
1. Te tukanga whakakōkō i te hau māori Ka tauhohe te hau māori ki te hau kōkō. I muri i te mimitinga o te waikawa hauwai hauwai i hangaia e te hauwai hauwai ki te wai, ka tangohia te toenga o te hauwai hauwai hauwai ki te rai, ā, ka whiwhihia te hua oti mā te whakamaroke, te pēhi, te whakatōtō me te whakahoro.
2. I tauhohe te chloromethane me te chloromethane ki te hau chlorine i raro i te mārama 4000kW hei whakaputa i te dichloromethane, i whakaotihia mā te horoi kawakore, te pēhi, te whakatōtō, te whakamaroke me te whakatikatika. Ko te hua matua ko te trichloromethane.
Haumarutanga:
1.Ngā whakatūpato mō te mahi:Āta karohia te maturuturunga o te kohu i te wā e mahi ana, ā, kakahuria ngā taputapu tiaki whaiaro e tika ana. Āta karohia te tuku i te mamaoa me ngā pata kohu ki te hau o te wāhi mahi. Mahi i roto i tētahi wāhi motuhake he pai te hauhautanga, ā, me tango te iti rawa. Me wātea tonu ngā taputapu urupare ohorere hei tinei i ngā ahi me te whakahaere i ngā maringi. Tērā pea kei roto tonu i ngā ipu rokiroki kau he toenga kino. Kaua e mahi i te taha o te whakarewa, te mura, ngā mata wera rānei.
2.Ngā whakatūpato rokiroki:Penapena ki tētahi wāhi hauhautanga, maroke, pai te hauhautanga, kāore he rā tika. Penapena kia matara atu i te pūtake wera, i te mura me ngā mea kāore e hototahi pērā i te waikura kaha, te waikawa kaha me te waikawa hauota. Penapena ki tētahi ipu kua tohua tika. Me taupokina pai ngā ipu kāore i whakamahia me ngā ipu kau. Āta tirohia te ipu i ngā wā katoa mō ngā hapa pērā i te pakaru, te maringi rānei. Kua whakarārangihia ngā ipu ki te kapia galvanized, ki te kapia Phenolic rānei hei whakaiti i te tūponotanga o te pirau o te methylene chloride. He iti te wāhi rokiroki. Whakapirihia ngā tohu whakatūpato ki ngā wāhi e tika ana. Me wehe te wāhi rokiroki mai i te wāhi mahi a ngā kaimahi, ā, me whakawhāiti te urunga atu ki te wāhi. Whakamahia ngā paipa kirihou kua tohua hei whakamahi me ngā matū hei tuku i ngā matū paitini. Ka taea e te rauemi te hanga hiko pateko ka puta ai te mura. Penapena ki tētahi wāhi hauhautanga, maroke, pai te hauhautanga, kia matara atu i te rā tika.
3.Te tākai me te kawe:Whakamahia ngā oko rino kua whakakikoruatia hei kati, ka taea te kawe i te 250kg ia oko, te waka tāke tereina, te motuka rānei. Me penapena ki te wāhi makariri, pōuri, maroke, pai te hauhautanga, me te aro ki te makuku.
