He whakarewa diol ether te propylene glycol ether me te ethylene glycol ether. He kakara ether pakupaku te propylene glycol methyl ether, engari kāore he kakara kaha whakapataritari, nā reira ka whānui ake te whakamahinga, ka haumaru ake hoki.
He aha ngā whakamahinga o te PM CAS 107-98-2?
1. Te nuinga o te wā e whakamahia ana hei whakarewa, hei whakamarara me hei waimeha, hei ārai huka wahie, hei tango, me ētahi atu.
2. 1-Methoxy-2-propanol CAS 107-98-2he takawaenga o te patu taru isopropylamine.
3. Whakamahia hei whakarewa, hei whakamarara, hei waimeha rānei i roto i ngā paninga, waituhi, tānga me te tae, patu pepeke, cellulose, acrylate me ētahi atu ahumahi. Ka taea hoki te whakamahi hei rauemi mata mō te hanga rauropi.
Ngā paninga wai-hāngai me te propylene glycol methyl ether:
I tēnei wā, ka taea te wehewehe i ngā paninga kei te mākete kia rite ki ō rātou āhua: paninga wai, paninga whakarewa, paninga paura, paninga totoka-teitei, me ētahi atu. I roto i ēnei, ko ngā paninga wai e pā ana ki ngā paninga e whakamahi ana i te wai hei waiwhakarewa. He iti rawa ngā whakarewa waro pūngoi, 5% ki te 10% noa iho o ngā paninga whakarewa, ā, he hua matomato, he hua hoa taiao.
Hei hanga i ngā paninga wai-tūāpapa matomato, ā-taiao hoki, he mea nui te whakamahi i tētahi rauemi matū mata – arā, ko te propylene glycol methyl ether. He aha te mahi a te propylene glycol methyl ether hei whakarewa i roto i ngā paninga wai-tūāpapa?
(1) Te whakarewa i ngā kapia paninga wai: Ko te propylene glycol methyl ether he whakarewa iti-kiato, he nui te kohua ka taea te whakarewa i te kapia i roto i ngā paninga wai hei hanga i tētahi ranunga ōrite, ā, ka pai ake te rere me te wairewa o ngā paninga wai.
(2) Te whakapai ake i ngā āhuatanga ā-tinana o ngā paninga wai: He iti ake te mātotoru, he nui ake te pēhanga kohu, nō reira ka taea te whakapai ake i ngā āhuatanga ā-tinana o ngā paninga wai, pērā i te whakanui ake i te matotoru o te paninga me te pupuri i te pumau o te paninga.
(3) Whakapai ake i te pakari o ngā paninga wai: He pai te pumau matū me ngā āhuatanga ārai mate, ka taea te whakarato i te pakari me te ātete matū pai mō ngā paninga wai.
(4) Whakaitihia te haunga o ngā paninga wai: He iti ake te haunga, ka taea te whakaiti i te haunga e tukuna ana e ngā paninga wai, ā, ka whakapai ake i te whakamarie me te haumaru o ngā paninga.
I roto i te poto, he pai ngā āhuatanga whakarewa me ngā āhuatanga ā-tinana o te propylene glycol methyl ether i roto i ngā paninga wai-hāngai, ā, ka taea e ēnei te tautoko nui mō te whakapai ake i te mahi me te roa o ngā paninga wai-hāngai. I taua wā anō, ka taea hoki e ia te whakaiti i te haunga o ngā paninga wai-hāngai me te tukunga o ngā matū kino, me te whakapai ake i te haumaru me te tiaki taiao o ngā paninga.
