Yintoni i-polycaprolactone?
Polycaprolactone, efinyeziweyo njenge-PCL, i-semi crystalline polymer kunye nemathiriyeli eyonakaliswa ngokupheleleyo.I-Polycaprolactone inokuthi ihlelwe kwibakala leyeza kunye nebakala lezoshishino ngendlela yeepowder, iincinci, kunye ne-microspheres.Ubunzima obuqhelekileyo bemolekyuli yi-60000 kunye ne-80000, kwaye ubunzima bemolekyuli obuphezulu okanye obuphantsi bunokwenziwa ngokwezifiso.
I-Polycaprolactone ineemfuno zokushisa eziphantsi kwaye inokubunjwa kumaqondo aphantsi.Inonamathela ngokugqwesileyo kunye nokuhambelana kakuhle kunye neentlobo ezahlukeneyo zeepolymers.Eyona nto inomtsalane ayiyotyhefu kwaye iyabola.Ngokuchanekileyo ngenxa yeempawu zayo eziphakamileyo ukuba isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo, ngakumbi kwicandelo lezonyango.Makhe sijonge kwiipropati ze-PCL?

Emva kokuqonda iimpawu ze-polycaprolactone ngasentla, sifike kumbuzo esiwuxhalabeleyo sonke.Oko kukuthi, i-polycaprolactone ingasetyenziselwa ntoni?
Ingasetyenziselwa ntoni i-polycaprolactone?
1. Imiba yezonyango
Ingasetyenziselwa i-suture kutyando kwaye inokufunxwa ngumzimba womntu.Isenokusetyenziswa kwizikhonkwane ze-orthopedic, i-resin bandages, ushicilelo lwe-3D, kunye neminye imiba.Ukongeza, ikwayinto ephambili ye "Inaliti yentombi".
2. Intsimi ye-polyurethane resin
Kwintsimi ye-polyurethane resin, inokusetyenziswa kwi-coatings, i-inki, i-adhesives eshushu enyibilikayo, i-adhesives yelaphu elingalukwanga, izixhobo zezihlangu, i-adhesives yesakhiwo, njl.Ngenxa yokumelana nobushushu obungcono, ukuchasa ukukhanya, kunye nokumelana nokwaluphala, ikwasetyenziswa kakhulu kwisikhumba sokwenziwa.
3. Izinto zokupakisha ukutya
Ngenxa yokonakala kwayo, i-polycaprolactone inokuphinda isetyenziswe kwiifilimu zokubumba kunye neebhokisi zokupakisha ukutya.Ngenxa yempembelelo yayo ephawulekayo yokumelana nokushisa, ingasetyenziselwa njengeebhokisi zokupakisha, ezingakhuseli kuphela indalo, kodwa ziqinisekisa ukhuseleko.
4. Amanye amabala
Iimodeli ezenziwe ngesandla, imibala ye-organic, i-powder coatings, ukuguqulwa kweplastiki, njl., kunokusetyenziswa kwizinto zokuncamathelisa.
Liliphi ithemba lepolycaprolactone?
Nangona i-polycaprolactone isetyenziswa ngokubanzi, amathuba ayo ophuhliso nawo angumbandela obalulekileyo oxhalabisayo.Okokuqala, sifunde ukuba i-polycaprolactone ineempawu zokuthotywa ngokupheleleyo.Ngophuhliso loluntu, ukuqonda kwabantu ngokukhuselwa kwendalo kuye kwanda, kwaye ukusetyenziswa kweeplastiki ze-biodegradable zingxamisekile.Ke ngoko, i-polycaprolactone inexabiso elikhulu lokusetyenziswa kwezonyango, ukuvelisa, kunye nemiba yoshishino, kunyeI-PCL iyodwa inokukhokela kwizinto ezininzi.Ngenkqubela phambili yobugcisa bezonyango, iteknoloji yoshicilelo lwe-3D iya isiba ngabantu abaqolileyo.Iqhele ukusetyenziswa kwicandelo lezonyango njengesixhobo sobunjineli se-tissue esinokuthi sifunxwe kwaye sikhutshwe ngumzimba womntu.Njengommeli wezinto ezitsha ze-biodegradable, i-polycaprolactone inethemba elihle lophuhliso, kwaye imfuno iya kwanda.Ndiyathemba ukuba eli nqaku liluncedo kuwe.
