Yintoni i-polycaprolactone?
I-Polycaprolactone, efinyeziweyo njenge-PCL, yi-semi crystalline polymer kwaye yinto ebola ngokupheleleyo. I-Polycaprolactone inokwahlulwahlulwa ibe yi-pharmaceutical grade kunye ne-industrial grade ngohlobo lwee-powders, amasuntswana, kunye nee-microspheres. Ubunzima be-molecular obuqhelekileyo buyi-60000 kunye ne-80000, kwaye ubunzima be-molecular obuphezulu okanye obuphantsi bunokwenziwa ngokwezifiso.
I-Polycaprolactone ineemfuno zobushushu obuphantsi kwaye inokubunjwa kumaqondo obushushu aphantsi. Inamathela kakuhle kwaye ihambelana kakuhle neendidi ezahlukeneyo zeepolymers. Eyona nto inomtsalane kukuba ayinatyhefu kwaye iyabola. Kungenxa yeempawu zayo eziphezulu ukuba isetyenziswa kakhulu kwiinkalo ezahlukeneyo, ingakumbi kwicandelo lezonyango. Makhe sijonge iimpawu ze-PCL?

Emva kokuqonda iimpawu ze-polycaprolactone ezingentla, sifikelele kumbuzo esixhalabeleyo sonke. Oko kukuthi, i-polycaprolactone ingasetyenziselwa ntoni?
Ingasetyenziselwa ntoni i-polycaprolactone?
1. Iinkalo zonyango
Ingasetyenziselwa ukuthungwa kotyando kwaye ingafunxwa ngumzimba womntu. Ingasetyenziselwa nakwizihlunu zamathambo, iibhandishi ze-resin, ukuprinta kwe-3D, kunye nezinye izinto. Ukongeza, ikwasisithako esiphambili se-"Maiden Needle".
2. Intsimi ye-polyurethane resin
Kwicandelo le-polyurethane resin, ingasetyenziswa kwiingubo, kwii-inki, kwii-adhesives ezishushu ezinyibilikayo, kwii-adhesives zelaphu ezingalukwanga, kwizinto zezihlangu, kwii-adhesives zesakhiwo, njl. Uninzi lweengubo zisetyenziswa njengee-primer zezithuthi, kwiingubo zomphezulu, nakwiingubo ezahlukeneyo zezixhobo zokwakha. Ngenxa yokumelana kwayo nobushushu okungcono, ukumelana nokukhanya, kunye nokumelana nokuguga, ikwasetyenziswa kakhulu kwisikhumba sokwenziwa.
3. Izixhobo zokupakisha ukutya
Ngenxa yokubola kwayo, i-polycaprolactone ingasetyenziswa nakwiifilimu zokubumba ukutya. Ngenxa yempembelelo yayo emangalisayo yokumelana nobushushu, ingasetyenziswa njengeebhokisi zokupakisha, ezingakhuseli nje kuphela okusingqongileyo, kodwa zikwaqinisekisa ukhuseleko.
4. Amanye amasimi
Iimodeli ezenziwe ngesandla, izinto zokufaka imibala eziphilayo, izinto zokugquma ngomgubo, utshintsho lweplastiki, njl.njl., nazo zingasetyenziswa kwizincamathelisi.
Yintoni enokwenzeka kwi-polycaprolactone?
Nangona i-polycaprolactone isetyenziswa kakhulu, amathuba ophuhliso lwayo nawo yingxaki ephambili exhalabisayo. Okokuqala, sifunde ukuba i-polycaprolactone ineempawu zokuwohloka ngokupheleleyo. Ngokuphuhla koluntu, ulwazi lwabantu ngokhuseleko lokusingqongileyo luye lwanda, kwaye ukusetyenziswa kweeplastiki ezinokubola kungxamisekile. Ke ngoko, i-polycaprolactone inexabiso elikhulu lokusetyenziswa kwiinkalo zonyango, zemveliso, nezemizi-mveliso, kwayeI-PCL yodwa enokukhokela kwizinto ezininzi. Ngokuphucuka kwetekhnoloji yezonyango, itekhnoloji yokuprinta ye-3D iya isiba mdala ngakumbi. Isetyenziswa kakhulu kwicandelo lezonyango njengesixhobo sobunjineli bezicubu esinokufunxwa kwaye sikhutshwe ngumzimba womntu. Njengommeli wezinto ezisandula ukwenziwa ezinokubola, i-polycaprolactone inethuba elihle lophuhliso, kwaye imfuno iya kukhula. Ndiyathemba ukuba eli nqaku liza kukunceda.
