Polycaprolactone CAS 24980-41-4

I. Mara Tānga 3D: Ngā mea pau tino pai mō te tino tika me te whakaritenga

I roto i te mara o te tānga 3D (hanga tāpiri), kua noho te polycaprolactone PCL hei tētahi o ngā rauemi tānga 3D pirau matua nā te iti o te ira rewa (tata ki te 60℃), te pai o te rere o te wai me te kaha o te here i waenga i ngā paparanga. He tino pai te polymer PCL mō ngā ara hangarau pēnei i te whakatauira Whakatakotoranga Fused (FDM) me te stereolithography, ā, he whānui te whakamahinga i roto i ngā āhuatanga e whai ake nei:

Te hanga tauira me te tauira whaiaro:He pāmahana whakapōturi te Polycaprolactone PCL, ā, he iti ake te tūponotanga kia piko, kia pakaru rānei i te wā e tā ana. Ka taea e ia te tārua tika i ngā hanganga uaua (pēnei i ngā tauira wāhanga mīhini me ngā tauira iti hoahoanga), ā, he maeneene te mata o ngā wāhanga kua tāia, kāore e hiahiatia he tukatuka nui i muri i te mahi. I taua wā, nā te āhuatanga pirau o te Polycaprolactone PCL e pai ai mō ngā tauira "whakamahinga kotahi" (pēnei i ngā tauira whakamātautau wāhanga motuka), e whakaiti ana i te para rauemi.

Tānga 3D koiora Hei rauemi he tino hototahi ki te koiora:He mea motuhake te polycaprolactone PCL i roto i te tānga o ngā tūāpapa hangarau kiko. Mā te whakarerekē i te taumaha ngota o te rauemi, mā te whakakotahi rānei ki ngā matū koiora pērā i te hydroxyapatite (HA) me te collagen, ka taea te whakarite i ngā tūāpapa porous e rite ana ki ngā whakaritenga tipu o ngā kiko pērā i te wheua me te kiriuhi. Ka taea te whakahoro haere i te tūāpapa i roto i te tinana, ka whakarato i te wāhi tautoko mō ngā kiko hou. I tēnei wā, kua whakamahia te polymer PCL i roto i ngā rangahau tānga hauora pērā i te whakatikatika wheua me te whakaora kiri.

I roto i ngā mara o te mātauranga me te auahatanga:Mā te iti o te ira rewa o te polycaprolactone PCL ka taea te tā me te kore e hiahiatia he taputapu pāmahana teitei, kia tino haumaru ai. He pai hei rauemi whakauru mō te tānga 3D i roto i ngā horopaki mātauranga. Ka whakamahia te polycaprolactone PCL hei hanga tauira whakaako (pēnei i ngā tauira okana tangata me ngā tauira hanganga matū ngota). I taua wā, ko tōna āhuatanga o te āta huri i te pāmahana rūma ka tautoko hoki i te mara hoahoa auaha i roto i te hanga whakaurunga toi, i ngā taputapu taonga takaro rānei me ngā āhua whakarerekē.

II. Te Marae Tākai Kai Whakakore: Ngā taurangi takirua mō te pirau matomato me te tiakitanga haumaru

I roto i te ao o ngā takai kai whakakorekore, kua noho te polycaprolactone PCL hei huarahi kē atu ki ngā kirihou kore-pirau tuku iho (pērā i te polyethylene me te polypropylene) nā te mea he tino pirau, he pai ngā āhuatanga ārai me te haumaru pa ki ngā kai, ā, ka āwhina i te whakaoti rapanga o te "parahanga mā". Ko ōna momo tono matua ko

Kiriata/pēke takai kai pirau:Ka taea te whakaranu me te whakarerekē i te PCL me ngā rauemi pūmua tūturu pērā i te māngaro me te waikawa polylactic (PLA) hei whakarei ake i te ngāwari me te ātete wai o ngā rauemi, ā, ka hangaia hei kiriata, hei putea tiaki rānei mō te tākai i ngā kai hou (pērā i ngā hua me ngā huawhenua) me ngā kai kua tunua - ka taea te whakamahi i tēnei momo tākai i roto i ngā taiao tūturu (pērā i te oneone me ngā āhuatanga whakapūhui). Ka taea e te polycaprolactone PCL te memeha haere hei hauhā me te wai i roto i ngā marama 6 ki te 12 me te kore e waiho he parahanga toenga. I taua wā, he tino pai te pumau matū o te pūmua PCL, ā, kāore e tauhohe ki ngā hinu, ki ngā matū waikawa rānei i roto i te kai, e tutuki ana i ngā paerewa haumaru mō ngā rauemi whakapā kai (pērā i te tiwhikete FDA).

Ngā ipu kai me ngā taputapu tēpu whakakorekore:Mā te werohanga whakarewa, mā te pēhi wera rānei, ka taea te whakakotahi i te polycaprolactone PCL me ngā muka tipu (pērā i ngā muka kakau witi, ngā muka pāpaka) hei hanga pouaka tina, pereti, maripi, marau me ētahi atu hua. Ehara i te mea he pai te kaha o tēnei momo hua ki te kawe kawenga me te ātete wera (ka taea te tu atu i ngā pāmahana kai wera o te 60-80℃), engari ka taea hoki te whakakore i te polymer PCL mā te whakawairakau i muri i te whakamahinga, kia kore ai e pāngia te taiao mō te wā roa e puta mai ana i ngā taputapu tēpu kirihou tuku iho. He tino pai mō ngā āhuatanga takai tuku iho auau teitei pērā i te tango kai me te kai tere.

III. Ngā Rauemi Pepa Hauora Marae: Ngā rauemi matua mō te hototahitanga koiora me te urutau mahi

I roto i te ao o ngā pereti hauora, kua noho te polycaprolactone (PCL) hei rauemi mata matua mō te hanga pereti whakatika hauora me ngā pereti tiaki nā te mea he pai rawa te haumaru koiora, te tere pirau ka taea te whakahaere me ngā āhuatanga miihini. Ko ōna huarahi matua ki te whakamahi ko:

Ngā papa whakatikatika hauora:I roto i ngā mara pēnei i te orthopedics me te niho, ka taea e te polycaprolactone PCL te whakarei ake i tōna kaha miihini mā te whakarerekētanga (pēnei i te whakakotahitanga o te hydroxyapatite me te tricalcium phosphate), ā, ka hangaia hei papa whakatika hapa wheua me ngā papa hanga wheua alveolar. I muri i te whakaurunga ki te tinana tangata, ka taea e tēnei momo papa te whakarato tautoko tonu mō ngā wheua kua pakaru engari ka pakaru haere me te whakaora anō i ngā wheua o te tinana, ka karo i te mōrearea o te pokanga tuarua hei tango. I taua wā, ka taea e te biocompatibility o te polycaprolactone PCL te whakaiti i te whakakorenga ārai mate i muri i te whakaurunga, te whakatairanga i te piri o ngā pūtau me te whakaurunga kiko, ā, kua whakamahia haumanutia i roto i ngā pokanga whakatika wheua iti rawa te whakaekenga.

Ngā papa tiaki hauora me ngā papa wehe:He tino pai ngā āhuatanga hanga kiriata me te ārai o te PCL, ā, ka taea te hanga hei papa wehe hauora (pēnei i ngā papa tiaki pakitara mō ngā rūma pokanga me ngā papa wehe mata mō ngā taputapu hauora). Ehara i te mea ka ārai noa tēnei momo papa i te urunga mai o ngā huakita me ngā huaketo, engari he ngāwari hoki, he ātete ki te patu huakita. Ka taea e ia te tu atu ki te murunga auau ki te waipiro me ngā patu huakita kei roto he chlorine, ā, ka pirau i muri i te maka atu, ka whakaiti i te pēhanga o te tukatuka para hauora. Hei tāpiri, ka taea hoki te whakakotahi i te polycaprolactone PCL me ngā kaihoko patu huakita (pēnei i ngā iona hiriwa) hei whakarei ake i te mahi patu huakita roa o ngā papa tiaki, kia pai ai mō ngā āhuatanga he tino nui ngā whakaritenga mō te horoi taiao, pēnei i ngā tari mate urutā me te icus.

IV. Ngā Marae Kē: Ngā mara toronga mahi

Haunga ngā wāhanga matua kua whakahuatia ake nei, he mahi anō tā te polycaprolactone PCL i roto i ngā āhuatanga maha:

Ngā paninga me ngā piripiri:Ko te polycaprolactone PCL, hei wāhanga matua o te hanga kiriata o ngā paninga wai, whakarewa rānei, ka taea te whakarei ake i te ngāwari, te ātete pānga me te ātete huarere o te paninga - hei tauira, ina whakamahia ki te paninga pakitara o waho o ngā paipa whakarewa, ka taea te whakaiti i te pakaru o te paninga i puta mai i te whakahekenga o ngā paipa nā ngā huringa pāmahana. Ka whakamahia te polycaprolactone PCL hei paninga mata mō ngā taonga takaro kirihou, ka ātete ake te paninga ki te kakahu me te kore e ngawari ki te tihore. Heoi anō, nā te mea kāore he paitini o te PCL, ka taea e ia te tutuki i ngā paerewa haumaru mō ngā taonga takaro a ngā tamariki. Hei tāpiri, mā te tāpiri i te polymer PCL ki ngā paninga rakau ka taea hoki te whakapai ake i te tae o te kakano rakau me te whakarei ake i te āhua o te kakano.

Ngā rauemi ahuwhenua:Ka hangaia te polycaprolactone PCL hei kiriata ahuwhenua pirau, e whakamahia ana mō te whakatipu tipu hua, te pupuri wai me te tongi. I muri i te pirau, ka taea te huri hei mea koiora oneone, hei karo i te parahanga oneone i puta mai i ngā kiriata toenga. Ka taea rānei te hanga hei kawe tongi tuku puhoi hei whakahaere i te tere tuku matūkai, ā, ka taea e te polymer PCL te whakapai ake i te tere whakamahinga tongi. Ko te āhuatanga "whakangaromanga whakahaere" o PCL e tino tutuki ana i ngā tono ahuwhenua mō te "mahi" me te "hoa taiao", ā, e whakamahia ana hei whakaoti rapanga parahanga o ngā rauemi ahuwhenua tuku iho.

Kaiwhakarerekē rauemi hiato:Ka whakaranua te polycaprolactone PCL ki ngā polyolefin, te polyester me ētahi atu rauemi hei whakapai ake i tōna ngāwari me te kaha o te pānga, kia pai ai mō ngā horopaki he nui ngā whakaritenga mō te mahi a ngā rauemi, pērā i ngā wāhanga o roto o ngā motuka me ngā anga taputapu kāinga.

Te whakarerekētanga muka/kakahu:Ka whakamahia te polycaprolactone PCL hei paninga, hei whakapiri rānei i ngā muka polyester me te miro hei whakarei ake i tō rātou ngāwari, te ātete ki te kakahu me ngā āhuatanga ārai-ngāwari. Hei tauira, mā te tāpiri paninga PCL ki ngā papanga kākahu hākinakina ka taea te whakatōtika ake i ngā papanga, ā, ka iti ake te ngāwari ki te whakarerekē. Mā te whakapiri PCL ki ngā muka kākahu hauora ka taea te whakarei ake i te mimiti makuku me te pupuri i te kākahu, te whakapai ake i tōna piri ki te kiri, me te whakaiti i te mamae i puta mai i te waku o te patunga.
