Whakamahinga
1,4-Pūtānediol (BDO)he rauemi mata matū waro nui, he whānuitia ngā tono. Ko ngā huarahi tono matua koia ēnei:
Te whakaputanga o te hua polyester
- Mō te hanga i te polybutylene terephthalate (PBT): He kirihou hangarau polyester thermoplastic tino pai te PBT. He pai ōna āhuatanga miihini, he ātete matū pai ki te waikura, he pai te whakamarumaru hiko, ā, he kaha te pumau o ngā āhuatanga. He whānuitia te whakamahinga i roto i te ao hikohiko me ngā taputapu hiko hei hanga i ngā whare taputapu hiko me ngā hononga. Ko ētahi wāhanga o te umanga motuka, pērā i ngā kakau tatau motuka me ngā parepare, ka hangaia hoki mā te whakamahi i ngā rauemi PBT.
- Mō te hanga polyurethane thermoplastic (TPU): Ka whakakotahi te TPU i te ngāwari o te rapa me te ngāwari o te tukatuka o te kirihou. He ātete ki te kakahu, he ātete ki te hinu, he ātete hoki ki te makariri. He maha ngā wā ka whakamahia hei hanga kapu hū, paipa, pūtu waea me te taura, whitiki kawe ahumahi, me ētahi atu. He rauemi mata nui te 1,4-Butanediol mō te hanga TPU, e whakarato ana i te hua ki te ngāwari me ngā āhuatanga kume pai.
Te hanga i te γ-butyrolactone me te N-methylpyrrolidone (NMP)
- γ-butyrolactone: He whakarewa tino pai rawa atu tēnei, he kaha te wairewa, ā, he pai te pānga ki te wairewa i ngā matū waro me ngā polymer maha. He whānuitia te whakamahinga i roto i ngā ahumahi paninga, waituhi, me te tā me te tae. Koinei hoki te rauemi tīmatanga mō te hanga i ngā momo mea kakara me ngā takawaenga rongoā, e taea ai te whakaputa mai i ngā momo matū pai me ngā hanganga me ngā mahi motuhake i muri mai.
- N-methylpyrrolidone: He whakarewa aprotic porowhita tēnei, e whakaatu ana i te kaha whakarewa pai rawa atu mō ngā rauemi waro, kore-waro, me te polymer maha kāore e rewa. He mea tino nui tēnei i roto i te hanga pākahiko lithium, e whakamahia ana hei whakarewa i ngā here, ngā rauemi hohe hiko, me ētahi atu. He mea nui anō hoki āna tono i roto i te hanga patu pepeke, te horoi hiko, me ngā tukanga tango me te wehenga.
Mō te hanga o te tetrahydrofuran (THF): He whakarewa pai rawa atu te Tetrahydrofuran, he pai te wairewa mō ngā maha o ngā matū waro taiao me ngā matū waro hanga. I roto i ngā taiwhanga hanga waro me ngā pūnaha tauhohenga o te hanga matū, he maha te whakamahinga hei whakarewa hei whakatairanga i ngā tauhohenga. Hei tāpiri, koia hoki te rauemi mata mō te hanga o te polytetrahydrofuran (PTMEG). Ka whakamahia te PTMEG hei hanga muka spandex me ngā elastomers polyurethane, hei whakarato i te pūtake rauemi tino ngāwari mō te kakahu, ngā kākahu hākinakina papai, me ētahi atu ahumahi.
Ngā Whakamahinga i roto i te ao hauora: Ka taea te whakamahi i te 1,4-Butanediol hei takawaenga rongoā hei whakauru ki te hanganga o ētahi ngota rongoā. Hei tauira, i roto i ngā mahi hanganga o ētahi rongoā steroid me ngā paturopi, ka whakamahia tōna mahi matū hei hanga me te whakarerekē i ngā hanganga o ngā ngota rongoā, hei whakahaere i te rangahau, te whakawhanaketanga, me te whakaputanga o ngā rongoā hou.
Te Tākai me te Tukunga
25KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Nō ngā taonga noa, ā, ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
