Chii chinonzi polycaprolactone?
Polycaprolactone, yakapfupikiswa sePCL, iri semi crystalline polymer uye chinhu chakaora zvachose.Polycaprolactone inogona kuiswa mugiredhi remishonga uye giredhi reindasitiri nenzira yehupfu, zvidimbu, uye microspheres.Iwo akajairwa mamorekuru huremu ari 60000 uye 80000, uye epamusoro kana akadzika mamorekuru huremu anogona zvakare kugadzirwa.
Polycaprolactone ine tembiricha yakaderera zvinodiwa uye inogona kuumbwa pakudziya kwakaderera.Iyo ine yakanakisa adhesion uye yakanaka kuenderana nemhando dzakasiyana dzepolymer.Chimiro chayo chinoyevedza hachina chepfu uye chinoora.Izvo chaizvo nekuda kwehunhu hwayo hwepamusoro hunoshandiswa zvakanyanya munzvimbo dzakasiyana siyana, kunyanya mune zvekurapa.Ngatitarisei zvinhu zvePCL?

Mushure mekunzwisisa maitiro epolycaprolactone pamusoro, tauya kumubvunzo watine hanya nawo tese.Ndiko kuti, chii chinogona kushandiswa polycaprolactone?
Chii chinogona kushandiswa polycaprolactone?
1. Mamiriro ezvokurapa
Inogona kushandiswa suture mukuvhiya uye inogona kutorwa nemuviri wemunhu.Inogona zvakare kushandiswa mumabhonzo emapfupa, resin mabhandeji, 3D kudhinda, uye zvimwe zvinhu.Mukuwedzera, iyo zvakare ndiyo inonyanya kukosha ye "Maiden Needle".
2. Polyurethane resin munda
Mumunda wepolyurethane resin, inogona kushandiswa mukuputira, ingi, zvinonamira zvinonyunguduka zvinopisa, zvinonamira machira asina kuruka, zvinhu zveshangu, zvinonamira zvechimiro, etc. Mazhinji machira anoshandiswa semaprimers emotokari, machira epamusoro, uye akasiyana ezvivakwa zvekuvaka.Nekuda kwekupisa kwayo kurinani, kusamira kwechiedza, uye kuramba kuchembera, inoshandiswawo zvakanyanya mumatehwe ekugadzira.
3. Zvokudya zvekuputira zvinhu
Nekuda kwekuderera kwayo, polycaprolactone inogona zvakare kushandiswa mukuvhuvhuta mafirimu uye mabhokisi ekurongedza echikafu.Nekuda kweiyo inoshamisa yekudzivirira kupisa mhedzisiro, inogona kushandiswa semabhokisi ekurongedza, ayo asingango chengetedza zvakatipoteredza, asi zvakare anochengetedza kuchengetedzwa.
4. Mimwe minda
Mamodheru akagadzirwa nemaoko, organic colorants, poda coating, mapurasitiki ekugadzirisa, nezvimwewo, anogona zvakare kushandiswa mukunamira.
Ndeipi tarisiro yepolycaprolactone?
Kunyangwe polycaprolactone ichishandiswa zvakanyanya, tarisiro yayo yekusimudzira inyaya yakakosha yekunetsekana.Chokutanga pane zvose, takadzidza kuti polycaprolactone ine maitiro ekuora zvachose.Nekuvandudzwa kwevanhu, kuziva kwevanhu nezvekuchengetedzwa kwezvakatipoteredza kwawedzera, uye kushandiswa kwemapurasitiki anoodegradable ndiko kukurumidza.Naizvozvo, polycaprolactone ine hukuru hwekushandisa kukosha mune zvekurapa, kugadzira, uye maindasitiri maficha, uyePCL chete inogona kutungamirira mune zvakawanda zvinhu.Nekufambira mberi kwehunyanzvi hwekurapa, tekinoroji yekudhinda ye3D iri kuwedzera kukura.Inowanzo shandiswa mumunda wekurapa setishu engineering scaffold zvinhu zvinogona kutorwa nekuburitswa nemuviri wemunhu.Semumiriri wezvichangobva kugadzirwa biodegradable zvinhu, polycaprolactone ine yakanaka budiriro tarisiro, uye kudiwa kuchave kuchiwedzera.Ndinovimba kuti chinyorwa ichi chinobatsira kwauri.
