Waa maxay polycaprolactone?
Polycaprolactone, oo loo soo gaabiyo PCL, waa polymer-ka-ka-soo-baxa ah iyo walxo gebi ahaanba la dumin karo. Polycaprolactone waxaa loo kala saari karaa darajada dawooyinka iyo heerka warshadaha qaab budo ah, qaybo, iyo microspheres. Miisaanka molecular ee caadiga ah waa 60000 iyo 80000, iyo ka sare ama ka hooseeya miisaanka unugyada sidoo kale waa la habeyn karaa.
Polycaprolactone waxay leedahay shuruudo heerkul hooseeya waxaana lagu qaabayn karaa heerkul hoose. Waxay leedahay adhesion aad u fiican iyo iswaafajin wanaagsan oo leh noocyo kala duwan oo polymers ah. Muuqaalkeeda ugu soo jiidashada badan waa mid aan sun ahayn iyo biodegradable. Waa si sax ah sababtoo ah sifooyinkeeda sare ayaa si weyn loogu isticmaalaa meelo kala duwan, gaar ahaan dhinaca caafimaadka. Aynu eegno sifooyinka PCL?

Ka dib markii la fahmo sifooyinka polycaprolactone ee kor ku xusan, waxaan u nimid su'aasha ah in aan dhammaanteen ka walaacsannahay. Taasi waa, maxaa polycaprolactone loo isticmaali karaa?
Maxaa polycaprolactone loo isticmaali karaa?
1. Dhinacyada caafimaadka
Waxaa loo isticmaali karaa tolitaanka qalliinka waxaana nuugi kara jidhka bini'aadamka. Waxa kale oo loo isticmaali karaa kabiyeyaasha lafaha, faashado resin, daabacaadda 3D, iyo dhinacyo kale. Intaa waxaa dheer, sidoo kale waa qaybta ugu muhiimsan ee "Maiden Needle".
2. Beerta xabagta polyurethane
Dhulka xabagta poliurethane, waxaa loo isticmaali karaa dahaarka, khadadka, xabagta dhalaalaysa kulul, xabagta dharka aan timaha lahayn, qalabka kabaha, xabagta qaabdhismeedka, iwm Sababtoo ah iska caabbinta kulaylka wanaagsan, caabbinta iftiinka, iyo caabbinta gabowga, waxaa sidoo kale si ballaaran loo isticmaalaa maqaarka macmalka ah.
3. Qalabka baakadaha cuntada
Hoos-u-dhaceeda awgeed, polycaprolactone sidoo kale waxaa loo isticmaali karaa filimada wax-ka-qabashada iyo sanduuqyada baakadaha cuntada. Sababtoo ah saameynteeda caabbinta kulaylka ee cajiibka ah, waxaa loo isticmaali karaa sanduuqyada baakadaha, taas oo aan ilaalinaynin oo kaliya deegaanka, laakiin sidoo kale waxay hubisaa badbaadada.
4. Beeraha kale
Moodooyinka gacanta lagu sameeyo, midabada organic, dahaarka budada ah, wax ka beddelka caaga ah, iwm, ayaa sidoo kale loo isticmaali karaa xabagta.
Waa maxay rajada polycaprolactone?
Inkasta oo polycaprolactone si ballaaran loo isticmaalo, rajada horumarinta ayaa sidoo kale ah arrin muhiim ah oo walaac leh. Ugu horreyntii, waxaan ogaanay in polycaprolactone uu leeyahay sifooyinka hoos u dhaca dhamaystiran. Horumarka bulshada, wacyiga dadka ee ilaalinta deegaanka ayaa kor u kacday, isticmaalka balaastikada noolaha ah waa mid degdeg ah. Sidaa darteed, polycaprolactone waxay leedahay qiimo isticmaalka weyn ee caafimaadka, wax soo saarka, iyo dhinacyada warshadaha, iyoPCL Keligiis ayaa hogaanka u qaban kara agabyo badan. Iyadoo horumarinta tignoolajiyada caafimaadka, tignoolajiyada daabacaadda 3D ayaa noqonaysa mid sii kordheysa oo qaangaar ah. Waxaa caadi ahaan loo isticmaalaa goobta caafimaadka sida sheyga injineernimada unugyada kaas oo la nuugi karo oo laga soo saari karo jidhka bini'aadamka. Iyada oo wakiil ka ah qalabka cusub ee la horumariyay ee biodegradable, polycaprolactone waxay leedahay rajo horumarineed oo wanaagsan, dalabkuna wuu sii kordhayaa. Waxaan rajeynayaa in maqaalkani uu ku caawin doono.
