1,4-Pūtānediol (BDO) He wai hinuhinu kore tae te mea kua aro nuitia e ngā momo ahumahi nā ōna āhuatanga ahurei me ōna whakamahinga maha. Ehara i te mea ka taea anake te whakaranu i tēnei matū ki te wai, ā, he mea tino pai hei whakarewa, engari ka taea hoki te whakamahi hei ārai huka kore paitini, hei whakapūhui kai, hei kaihoko hygroscopic hoki. Ka horapa ōna whakamahinga ki ngā ahumahi rongoā me te kai tae atu ki te hanga rauropi, ā, he mea nui hei matū matū i roto i ngā tukanga hanga o nāianei.
Ko tētahi o ngā āhuatanga tino kitea o1,4-butanediolko tōna kaha ki te mahi hei whakarewa. I roto i te mara o te matū waro, he mahi nui tā ngā whakarewa ki te whakahaere i ngā tauhohenga me te whakarewa i ngā matū. Nā te whakauru o te BDO ki te wai ka taea te whakamahi pai i roto i ngā momo tauhohenga matū, inā koa i roto i te chromatography hau e mahi ana hei wai pumau. He mea nui tēnei āhuatanga mō te wehenga me te tātari i ngā ranunga uaua, ka waiho te BDO hei taputapu whai hua mō ngā kaimātai matū me ngā kairangahau.
Haunga tōna tūranga hei whakarewa, e mōhiotia ana te 1,4-butanediol mō ōna āhuatanga kore-paitini, ā, he mea tino pai mō te umanga kai. Hei emulsifier kai, ka āwhina a BDO ki te whakau i ngā ranunga ka wehe kē, pērā i te hinu me te wai. He mea nui rawa tēnei āhuatanga ina hangaia he ranu, he mea kakara me ētahi atu hua kai e hiahia ana ki te kakano me te āhua ōrite. Mā te āhua haumaru o BDO ka taea te whakamahi me te kore e tūpono ki te hauora o ngā kaihoko, ka whakanui ake i tōna rongonui i roto i ngā tono kai.
Hei tāpiri, ko te āhua hygroscopic o1,4-pūtanedioMā te l ka taea e ia te mimiti i te makuku mai i te taiao, ka waiho hei matū hohe i roto i ngā momo whakatakotoranga. He tino whai hua tēnei āhuatanga i roto i te umanga rongoā, he mea nui te pupuri i te pumau me te whai huatanga o ngā matū hohe. Mā te tāpiri i te BDO ki ngā whakatakotoranga, ka taea e ngā kaihanga te whakaroa i te roa o te wā rokiroki me te mahi a ā rātou hua, me te whakarite kia tutuki i a rātou ngā paerewa teitei o te umanga hauora.
Te maha o ngā āhuatanga1,4-butanediolKei tua atu i te kai me te rongoā. I roto i te hanganga rauropi, he poraka hanga te BDO mō te hanga i ngā momo matū me ngā rauemi. Ka taea e ia te mahi i ngā tauhohenga polymerization kia taea ai te huri hei polybutylene terephthalate (PBT), he thermoplastic e whakamahia whānuitia ana i roto i te hanga o ngā wāhanga motuka, ngā wāhanga hiko me ngā hua kaihoko. E whakaatu ana tēnei panoni i te tūranga o BDO hei matū matua mō te hanga hou.
I te whanaketanga tonu o ngā ahumahi me te rapu i ngā otinga tauwhiro, e matapaetia ana ka piki ake te hiahia mō ngā matū kore-paitini, maha-mahi pērā i te 1,4-butanediol. Ko ōna whakamahinga i roto i ngā mara kanorau pērā i te kai, te rongoā me te pūtaiao rauemi e whakaatu ana i tōna hiranga i roto i ngā tukanga matū o nāianei. Mā te rangahau me te whanaketanga tonu, tera pea ka whānui ake ngā whakamahinga pea a BDO, ka whakatakoto huarahi mō ngā hua me ngā otinga auaha e tutuki ai ngā hiahia o tētahi ao e huri haere tonu ana.
Hei whakamutunga,1,4-butanediol He matū whakamiharo tēnei e whai wāhi nui ana ki ngā momo ahumahi. Nā ōna āhuatanga hei whakarewa, hei ārai huka kore-paitini, hei whakapūmau kai, hei kaihopu waiora hoki, he rauemi nui tēnei i roto i ngā ahumahi rongoā me te kai, tae atu ki te hanga rauropi. I a tātou e tūhura tonu ana i te pūmanawa o tēnei matū maha-whakamahinga, e mārama ana ka whai wāhi nui tonu te 1,4-butanediol ki te whanaketanga o te matū me te ahumahi hou.
