Iyini i-polycaprolactone?
I-Polycaprolactone, efushanisiwe njenge-PCL, iyi-polymer e-semicrystalline futhi iyinto eyonakala ngokuphelele. I-Polycaprolactone ingahlukaniswa ngokwezinga lezemithi kanye nebanga lezimboni ngendlela yezimpushana, izinhlayiya, nama-microspheres. Izisindo ezijwayelekile zamangqamuzana ziyi-60000 kanye ne-80000, futhi izisindo zamangqamuzana eziphakeme noma eziphansi nazo zingenziwa ngokwezifiso.
I-Polycaprolactone inezidingo zokushisa eziphansi futhi ingabunjwa emazingeni okushisa aphansi. Inokunamathela okuhle kakhulu nokuhambisana okuhle nama-polymer ahlukahlukene. Isici sawo esikhanga kakhulu asinabo ubuthi futhi siyabola. Kungenxa yezimpawu zayo eziphakeme ukuthi isetshenziswa kabanzi emikhakheni ehlukahlukene, ikakhulukazi emkhakheni wezokwelapha. Ake sibheke izakhiwo ze-PCL?

Ngemva kokuqonda izici ze-polycaprolactone ngenhla, sifike embuzweni esikhathazeke ngawo sonke. Okusho ukuthi, i-polycaprolactone ingasetshenziselwa ini?
I-polycaprolactone ingasetshenziselwa ini?
1. Izici zezokwelapha
Ingasetshenziselwa i-suture ekuhlinzeni futhi ingamuncwa umzimba womuntu. Ingasetshenziswa futhi kuma-splints amathambo, amabhandeshi e-resin, ukuphrinta kwe-3D, nezinye izici. Ngaphezu kwalokho, futhi iyisithako esiyinhloko "Inaliti Yentombi".
2. Inkambu ye-polyurethane resin
Emkhakheni we-polyurethane resin, ingasetshenziswa kuma-coatings, oyinki, izinto zokunamathisela ezincibilikayo ezishisayo, izinamatheliso zendwangu ezingalukiwe, izinto zezicathulo, izinamatheliso zesakhiwo, njll. Iningi lezingubo ezimboziwe lisetshenziswa njengeziqalo zezimoto, izimbotshana ezingaphezulu, kanye nezinhlobonhlobo zezinto zokwakha. Ngenxa yokumelana nokushisa okungcono, ukumelana nokukhanya, nokumelana nokuguga, ibuye isetshenziswe kakhulu esikhumbeni sokwenziwa.
3. Izinto zokupakisha ukudla
Ngenxa yokonakala kwayo, i-polycaprolactone ingasetshenziswa futhi kumafilimu okubumba amabhodlela namabhokisi okupakisha okudla. Ngenxa yomphumela wayo ophawulekayo wokumelana nokushisa, ingasetshenziswa njengamabhokisi okupakisha, angavikeli nje imvelo, kodwa futhi aqinisekise ukuphepha.
4. Ezinye izinkambu
Amamodeli enziwe ngezandla, ama-colorants aphilayo, ama-powder coatings, ukuguqulwa kwepulasitiki, njll., angasetshenziswa futhi ekunamathiseleni.
Liyini ithemba le-polycaprolactone?
Nakuba i-polycaprolactone isetshenziswa kabanzi, amathemba ayo okuthuthukiswa nawo ayindaba ebalulekile yokukhathazeka. Okokuqala, sifunde ukuthi i-polycaprolactone inezici zokuwohloka okuphelele. Ngokuthuthuka komphakathi, ukuqwashisa kwabantu ngokuvikelwa kwemvelo kuye kwanda, futhi ukusetshenziswa kwamapulasitiki abolayo kuyaphuthuma. Ngakho-ke, i-polycaprolactone inenani elikhulu lokusetshenziswa kwezokwelapha, ukukhiqiza, kanye nezici zezimboni, kanyeI-PCL iyodwa ingahola ezintweni eziningi.Ngokuthuthuka kobuchwepheshe bezokwelapha, ubuchwepheshe bokuphrinta be-3D buya ngokuya buvuthwa. Ivame ukusetshenziswa emkhakheni wezokwelapha njengento yobunjiniyela bezicubu engamuncwa futhi ikhishwe ngumzimba womuntu. Njengommeleli wezinto ezisanda kuthuthukiswa ezibolayo, i-polycaprolactone inethuba elihle lokuthuthuka, futhi isidingo sizokhula. Ngethemba ukuthi lesi sihloko siwusizo kuwe.
