Bis(4-hydroxyphenyl) Sulfone CAS 80-09-1
Ko te Bisphenol S (BPS), nama CAS 80-09-1 me te ingoa matū ko te Bis(4-hydroxyphenyl) Sulfone, he matū kakara kei roto he hanganga bisphenol e honoa ana e te rōpū sulfone. Nā te kaha o te polarity me te pumau o te rōpū sulfone (-SO₂-) i roto i tōna hanganga ngota, he rerekē rawa tōna mahi i tērā o te bisphenol A (BPA) noa, ā, nā reira i whānuitia ai tōna whakamahinga i roto i ngā ahumahi matū, rauemi, me ngā ahumahi matū o ia rā.

1. Ngā Rauemi Pūmua: Ngā Monomera Matua me ngā Kaiwhakarerekē
Te Hanganga Resin Epoxy: Hei monomer whakakapinga bisphenol A, ka whakapūmauhia ki te epichlorohydrin hei whakaputa i te "resin epoxy momo-S bisphenol." Ka whakaatuhia e tēnei resin te ātete wera kua whakanuia (te pāmahana whakawhiti karāhe (Tg) 30-50°C teitei ake i te resin epoxy bisphenol A), te ātete waikura, me te kaha miihini. Ka whakamahia te Bis(4-hydroxyphenyl) sulfone i roto i ngā rauemi takai hiko pāmahana-teitei, ngā piripiri hanganga rererangi, me ngā paninga matū ārai-waikura.
Te Hanganga Polycarbonate (PC): E whakamahia ana i roto i te hangahanga o te "bisphenol S-type PC," e whakapai ake ana i te ātete wera me te ātete tawhito UV o ngā rauemi PC. He pai mō ngā tono pēnei i ngā whare rama o waho me ngā tuanui rā o ngā motuka.
Whakarerekētanga Resin Polysulfone: Ka whakamahia te Bis(4-hydroxyphenyl) sulfone hei comonomer i roto i te hanganga o ngā kapia polysulfone, hei whakarei ake i te ātete whakarewa me ngā āhuatanga miihini o te kapia. Ka whakamahia i roto i ngā taputapu hauora kounga teitei (pēnei i ngā dialyzer) me ngā whare wāhanga hiko.
2. Ngā Matū me ngā Kakahu o ia Rā: Ngā Tāpiringa Mahi
Ngā Rauemi Mata Whakapaipai: Ka tāpirihia te Bis(4-hydroxyphenyl) sulfone ki ngā pare rā me ngā hua tiaki kiri hei mimiti UV, hei ārai mate rānei. Mā te whakamahi i ngā āhuatanga ārai mate o te rōpū phenolic hydroxyl me te pumau o te rōpū sulfone, ka whakaitihia te kino o te UV ki te kiri, ā, ka roa ake te ora o te hua.
Āwhina Kakahu: Ka whakamahia te Bis(4-hydroxyphenyl) sulfone i roto i te hanga i ngā mea ārai mura kakahu, i ngā mea ārai pūmau rānei. Mā te tauhohe ki ngā rōpū hydroxyl i runga i te mata o te muka hei hanga i tētahi hononga pumau, ka hoatu he āhuatanga ārai mura me te ārai pūmau ki te kakahu. He pai mō ngā kakahu pēnei i te kākahu mahi me ngā ārai.
3. Ngā Rauemi me ngā Kirihou e Pā Ana ki te Kai: He Whakakapinga mō te Bisphenol A
Ngā Rauemi Tākai Kai: Ka whakamahia te Bisphenol S i roto i te hanga paninga kapia epoxy kounga kai (pēnei i te paninga o roto o ngā kēne) me ngā kirihou pa ki te kai (pēnei i ngā pounamu pēpi me ngā taputapu tēpu). Nā te iti o te hekenga, ka tutuki i a ia ngā paerewa haumaru pa ki te kai pēnei i te EU Directive 10/2011 me te China GB 4806.
Paninga Pepa Wera: Hei whakakapi mō te BPA, ka whakamahia ngātahitia me ngā tae leuco me ngā kaiwhakawhanake tae mō ngā pepa wera (pērā i te pepa rehita moni o te hūpāmakete me ngā tapanga tuku tere) hei ārai i te hekenga o te BPA ki roto i te tinana tangata mā te pa ki te kiri.
4. Ētahi atu Taupānga
Ngā Takawaenga Rongoā: Ka whakamahia te Bisphenol S i roto i te hanga rongoā me te mahi ārai-mumura me te mahi patu huakita.
Ngā Tauhohenga Matū Tātari: Ka whakamahia te Bisphenol S hei tohu waikawa-pūtake, hei tauhohenga matatini rānei mō te tātari tauanga o ngā katote konganuku (pērā i te rino me te parahi). Ka hangaia e te rōpū phenolic hydroxyl he matatini pumau me ngā katote konganuku, ka puta he huringa tae āhua.
Te waikawa kaha:Kei roto i te ngota Bisphenol S ngā rōpū phenolic hydroxyl e rua me tētahi rōpū sulfone kaha e tango ana i te irahiko (-SO₂-), ā, he waikawa ake i ngā phenols noa.
Te tauhohenga phenolic noa:He nui te kaha o ngā rōpū phenolic hydroxyl e rua i roto i te ngota Bis(4-hydroxyphenyl) Sulfone, ā, ka taea e rātou te whai i ngā tauhohenga matū maha pērā i te etherification, te esterification, me te polycondensation, hei tauira, te tauhohenga ki te formaldehyde hei hanga kapia.
Te pumau pai:He ātete wera, he ātete waikura, he pumau hoki tō te Bis(4-hydroxyphenyl) Sulfone, engari ka pirau pea i raro i ngā āhuatanga waikawa kaha, kawakore kaha, kawakore kaha rānei.
Te pumau wera teitei:Kei runga ake i te 300℃ te pāmahana pirau wera o Bisphenol S, e whakaatu ana i te pumau pai i te wā e tukatukahia ana i te pāmahana teitei.
He iti te paitini:He matū iti te paitini o te Bisphenol S.
Ka taea te whakamahi i te Bisphenol S hei whakakapi mō te bisphenol A:Nā te mea he nui ngā tūponotanga hauora o te bisphenol A, ka taea te whakamahi i te bisphenol S hei whakakapi mōna i roto i te hanganga o ngā rauemi ngota ngota teitei pērā i te polycarbonate me te epoxy resin, ā, he nui ake te pumau wera, te pumau matū me ngā āhuatanga hangarau o ngā rauemi ngota ngota teitei kua hangaia.
