Te āhuatanga kōwhiringa whakarewa
Ka wairewa te polyethylene chlorinated i roto i ngā whakarewa pērā i te toluene, i te xylene rānei. Ka whakapai ake i te wairewatanga o te ester mā te whakarewa i ngā esters pērā i te butyl acetate, te PMA rānei (propylene glycol methyl ether acetate). Ka taea hoki e ngā whakarewa pōro pērā i te methanol me te ethanol te taunekeneke ki ngā ngota chlorine i roto i ngā ngota polyethylene chlorinated hei whakatairanga i tō rātou wairewatanga. Nā te mea he ngota chlorine kei runga i ngā mekameka o ngā ngota polyethylene chlorinated, ā, ka taea e ngā whakarewa pōro te taunekeneke pai ki a rātou.
Ētahi atu āhuatanga e pā ana ki te whakakorenga me ngā mahi e pā ana
Te nui o te whakakōkōwai: Ka teitei ake te nui o te whakakōkōwai o te polyethylene whai kōkōwai, ka nui ake te wairewa, nō reira, he māmā ake te wairewa o te polyethylene whai kōkōwai me te nui o te whakakōkōwai.
Te Pāmahana: I te nuinga o te wā, i te pikinga o te pāmahana, ka piki ake hoki te wairewatanga o te polyethylene chlorine i roto i te whakarewa. Mā te whakanui ake i te pāmahana ka āwhina i te tere o te wairewatanga, nā te mea ka taea e ngā pāmahana teitei te whakatairanga i te nekehanga o ngā mekameka polymer, ā, ka tere ake te taunekeneke ki ngā whakarewa. Heoi, me whai whakaaro ki te haumaru i te wā e whakamahia ana hei ārai i ngā aituā pēnei i te wera (tirohia te awe o te pāmahana ki te wairewatanga o ngā rauemi polymer rite pēnei i te waipiro polyvinyl).
Te whakaoho (tirohia te mahi ina whakarewahia ngā rauemi rite): Ahakoa kāore i te whakahuatia te mahi a te whakaoho i te wā e whakarewahia ana te polyethylene whai kōro, mai i te tirohanga o te whakarewatanga o ngā rauemi polymer rite, ka āwhina te whakaoho ki te whakatairanga i te whakaranu ki ngā whakarewa, te whakaiti i ngā rerekētanga kukū ā-rohe, me te tere ake i te tukanga whakarewatanga. Ina tāpirihia te paura polyethylene whai kōro ki te whakarewa, ka taea te tīmata i te whakaoho i te wā kotahi hei whakatairanga i te whakarewatanga.
Te wā whakarewa: Hei whakarite kia rewa katoa te polyethylene whai kōroteina, me nui te wā e hiahiatia ana, pērā i te waipiro polyvinyl e hiahia ana kia nui te wā hei whakarewa. Heoi, me whakatau pea te wā motuhake i runga i ngā āhuatanga maha pēnei i te nui o te polyethylene whai kōroteina, te nui o te whakarewa, me te pāmahana.
