Kuyini i-polycaprolactone?
I-Polycaprolactone, efushaniswe ngokuthi i-PCL, iyi-polymer eyi-semi crystalline futhi iyinto ebola ngokuphelele. I-Polycaprolactone ingahlukaniswa ngebanga lemithi kanye nebanga lezimboni ngesimo sama-powder, izinhlayiya, nama-microspheres. Isisindo sama-molecule esivamile singama-60000 kanye nama-80000, kanti isisindo sama-molecule esiphezulu noma esiphansi singenziwa ngezifiso.
I-Polycaprolactone inezidingo eziphansi zokushisa futhi ingabunjwa emazingeni okushisa aphansi. Inamathela kahle kakhulu futhi ihambisana kahle nezinhlobonhlobo zama-polymer. Isici sayo esikhangayo kakhulu asinobuthi futhi siyabola. Kungenxa yezici zayo eziphakeme ukuthi isetshenziswa kabanzi emikhakheni ehlukahlukene, ikakhulukazi emkhakheni wezokwelapha. Ake sibheke izakhiwo ze-PCL?

Ngemva kokuqonda izici ze-polycaprolactone ngenhla, sesifikile embuzweni esikhathazekile ngawo sonke. Okungukuthi, i-polycaprolactone ingasetshenziselwani?
Yini i-polycaprolactone engasetshenziswa?
1. Izici zezokwelapha
Ingasetshenziswa ekuthungeni ekuhlinzeni futhi ingamuncwa ngumzimba womuntu. Ingasetshenziswa nasezintweni zokubopha amathambo, amabhandeji e-resin, ukuphrinta kwe-3D, nezinye izici. Ngaphezu kwalokho, futhi iyisithako esiyinhloko se-"Maiden Needle".
2. Insimu ye-polyurethane resin
Emkhakheni we-polyurethane resin, ingasetshenziswa ekumbozeni, kuyinki, ekunamathiseleni okushisayo okuncibilikayo, ekunamathiseleni kwendwangu okungalukiwe, ezintweni zezicathulo, ekunamathiseleni kwesakhiwo, njll. Iningi lezimbozo lisetshenziswa njengezinto zokuqalisa izimoto, ezimbozeni zangaphezulu, kanye nasezimbozweni zezinto zokwakha ezahlukahlukene. Ngenxa yokumelana kwayo nokushisa okungcono, ukumelana nokukhanya, kanye nokumelana nokuguga, isetshenziswa kabanzi nasezikhumbeni zokwenziwa.
3. Izinto zokupakisha ukudla
Ngenxa yokubola kwayo, i-polycaprolactone ingasetshenziswa futhi kumafilimu okubumba ama-blow kanye namabhokisi okupakisha ukudla. Ngenxa yomphumela wayo omangalisayo wokumelana nokushisa, ingasetshenziswa njengamabhokisi okupakisha, okungavikeli nje kuphela imvelo, kodwa futhi okuqinisekisa ukuphepha.
4. Ezinye izinkambu
Amamodeli enziwe ngezandla, izinto zokufaka imibala eziphilayo, izinto zokumboza ngempuphu, izinguquko zepulasitiki, njll., angasetshenziswa nasezintini zokunamathisela.
Iyini ingozi ye-polycaprolactone?
Nakuba i-polycaprolactone isetshenziswa kabanzi, amathuba okuthuthuka kwayo nawo ayindaba ebalulekile. Okokuqala, sifunde ukuthi i-polycaprolactone inezici zokuwohloka okuphelele. Ngokuthuthuka komphakathi, ukuqwashisa kwabantu ngokuvikelwa kwemvelo kuye kwanda, futhi ukusetshenziswa kwepulasitiki ebolayo kuyaphuthuma. Ngakho-ke, i-polycaprolactone inenani elikhulu lokusetshenziswa ezicini zezokwelapha, zokukhiqiza, kanye nezezimboni, kanyeI-PCL iyodwa engahola ezintweni eziningi. Ngokuthuthuka kobuchwepheshe bezokwelapha, ubuchwepheshe bokuphrinta be-3D buya ngokuya bukhula. Buvame ukusetshenziswa emkhakheni wezokwelapha njenge-scaffold yobunjiniyela bezicubu engamuncwa futhi ikhishwe ngumzimba womuntu. Njengommeleli wezinto ezisanda kuthuthukiswa ezibolayo, i-polycaprolactone inethuba elihle lokuthuthukiswa, futhi isidingo sizokhula. Ngithemba ukuthi lesi sihloko sizokusiza.
