Waikawa Sulfoisophthalic Tote Monosodium CAS 6362-79-4
Ko te tote monosodium waikawa 5-Sulfoisophthalic (CAS 6362-79-4, ingoa Ingarihi: Ko te 5-sulfoisophthalic acid monosodium (tote) he takawaenga hanga waro nui, nō roto i ngā matū whakaputa waikawa dicarboxylic kakara kua whakarerekētia kua sulfonated. Ko tōna hanganga ngota i ahu mai i te waikawa isophthalic hei rōpū matua, me te rōpū waikawa sulfonic (-SO₃H) i whakaurua ki te tūranga 5 o te mowhiti benzene ka hanga he tote me te konutai.
Mai i te tirohanga o ngā āhuatanga ā-tinana me te matū, ko te tote monosodium waikawa 5-Sulfoisophthalic ka puta he paura mā, me te ira rewa o te 373℃. I te 20℃, ko tōna mātotoru he 1.87, ā, he pai te wairewatanga ki te wai (380g/L). I te 20℃, ko tōna tauwehenga waikawa (pKa) he 4.1, ā, i te 23℃, ko tōna LogP he -1.7. I te katoa. He pumau te āhua o te konutai m-5-sulfonate, ā, he ngāwari te wairewa i roto i te wai, he mea pai mō ngā whakamahinga pūnaha wai.

1. Te mara o ngā rauemi polymer
Ka whakamahia te tote monosodium waikawa 5-Sulfoisophthalic hei monomer copolymer mō te hanga "polyester whakarerekētia": ka copolymerized ki te waikawa terephthalic me te ethylene glycol, ā, ka whakaurua ngā rōpū sodium sulfonate hei whakapai ake i te hydrophilicity me te tae o te polyester, e whakamahia ana hei hanga muka polyester e ngāwari ana te tae me ngā paninga polyester wai-pūtake.
Te whakarite i te "kapia whakawhiti katote": Ka taea te whakamahi i ngā rōpū carboxyl me ngā rōpū konutai sulfonate hei rōpū whakawhiti katote mō te hanga i ngā kapia whakangawari wai me ngā kapia mimiti katote konganuku taumaha.
2. Te tānga kakahu me te mara tae
Hei "kaihoko whakataurite": I roto i te tae o ngā muka hangai pēnei i te polyester me te nairon, mā te tāpiri i te waikawa konutai isophthalic 5-sulfonate ka taea te whakahaere i te tere mimiti o te tae, te karo i te tae kore taurite, me te whakapai ake i te ōritetanga me te pumau o te tae o te tae kakahu.
3. Te mara paninga me ngā piripiri.
Mō ngā "paninga wai": Hei tāpiri mahi, ka whakapai ake te tote monosodium waikawa 5-Sulfoisophthalic i te marara me te ātete wai o te paninga, ka whakaiti i te wehewehenga o te paninga, ā, ka whakarei ake i te piri i waenga i te paninga me te papa.
"Pīpiri wai-whakarerekētia": Kua whakakotahitia ki te acrylate, ka whakarei ake te tote monosodium waikawa 5-Sulfoisophthalic i te ātete ki te huarere me te ngāwari o te pīpiri, he pai mō te here i ngā rauemi pēnei i te rakau me te kirihou.
