Kodi polycaprolactone ndi chiyani?

Polycaprolactone, yofupikitsidwa ngati PCL, ndi polima wa semi crystalline komanso zinthu zowonongeka kotheratu. Polycaprolactone akhoza m'gulu la mankhwala kalasi ndi mafakitale kalasi mu mawonekedwe a ufa, particles, ndi microspheres. Miyeso yodziwika bwino ya mamolekyulu ndi 60000 ndi 80000, ndipo masikelo apamwamba kapena otsika amathanso kusinthidwa makonda.

Polycaprolactone ili ndi zofunika kutentha kochepa ndipo imatha kuumbidwa pa kutentha kochepa. Ili ndi zomatira zabwino kwambiri komanso zogwirizana bwino ndi ma polima osiyanasiyana. Chochititsa chidwi kwambiri ndi chosaopsa komanso chosawonongeka. Ndi chifukwa cha makhalidwe ake apamwamba omwe amagwiritsidwa ntchito kwambiri m'madera osiyanasiyana, makamaka m'chipatala. Tiyeni tiwone zomwe PCL ili nazo?

Makhalidwe a polycaprolactone:

Pambuyo pomvetsetsa makhalidwe a polycaprolactone pamwambapa, tabwera ku funso limene tonsefe timakhudzidwa nalo. Ndiko kuti, polycaprolactone ingagwiritsidwe ntchito chiyani?

Kodi polycaprolactone ingagwiritsidwe ntchito bwanji?

1. Mbali zachipatala

Itha kugwiritsidwa ntchito ngati suture mu opaleshoni ndipo imatha kuyamwa ndi thupi la munthu. Itha kugwiritsidwanso ntchito pamipando ya mafupa, mabandeji a utomoni, kusindikiza kwa 3D, ndi zina. Kuonjezera apo, ndilo gawo lalikulu la "Maiden Needle".

2. Munda wa utomoni wa polyurethane

M'munda wa polyurethane utomoni angagwiritsidwe ntchito zokutira, inki, otentha kusungunula zomatira, sanali nsalu nsalu zomatira, zipangizo nsapato, zomatira structural, etc. zokutira ambiri ntchito monga zoyambira magalimoto, zokutira pamwamba, ndi zokutira zosiyanasiyana zomangira. Chifukwa cha kukana kutentha kwabwino, kukana kuwala, komanso kukana kukalamba, amagwiritsidwanso ntchito kwambiri pazikopa zopangira.

3. Zida zoyikamo chakudya

Chifukwa cha kuwonongeka kwake, polycaprolactone itha kugwiritsidwanso ntchito m'mafilimu owumba ndi mabokosi opangira zakudya. Chifukwa cha mphamvu yake yotsutsa kutentha, ingagwiritsidwe ntchito ngati mabokosi oyikapo, omwe samangoteteza chilengedwe, komanso amateteza chitetezo.

4. Minda ina

Zitsanzo zopangidwa ndi manja, zopaka utoto, zokutira ufa, zosintha zapulasitiki, ndi zina zambiri, zitha kugwiritsidwanso ntchito pazomatira.

Kodi chiyembekezo cha polycaprolactone ndi chiyani?

Ngakhale kuti polycaprolactone imagwiritsidwa ntchito kwambiri, ziyembekezo zake zachitukuko ndizofunikanso kwambiri. Choyamba, taphunzira kuti polycaprolactone ili ndi zizindikiro zowonongeka kwathunthu. Ndi chitukuko cha anthu, kuzindikira kwa anthu za kuteteza chilengedwe kwawonjezeka, ndipo kugwiritsa ntchito mapulasitiki owonongeka ndi kofunika mwamsanga. Chifukwa chake, polycaprolactone ili ndi phindu lalikulu pamagwiritsidwe azachipatala, kupanga, ndi mafakitale, ndiPCL yekha akhoza kutsogolera mu materials.Ndi kupita patsogolo kwa luso lachipatala, 3D kusindikiza luso akukhala okhwima. Amagwiritsidwa ntchito kwambiri m'zachipatala ngati scaffold scaffold material yomwe imatha kuyamwa ndikuchotsedwa ndi thupi la munthu. Monga woimira zinthu zomwe zangopangidwa kumene, polycaprolactone ili ndi chiyembekezo chabwino cha chitukuko, ndipo kufunikira kukukulirakulira. Ndikukhulupirira kuti nkhaniyi ndi yothandiza kwa inu.
