Waa maxay polycaprolactone?
Polycaprolactone, oo loo soo gaabiyo PCL, waa polymer nus-crystalline ah waana walax gebi ahaanba burburi karta. Polycaprolactone waxaa loo kala saari karaa heerka daawada iyo heerka warshadaha iyadoo loo eegayo budo, walxo, iyo microspheres. Miisaanka molecular-ka caadiga ah waa 60000 iyo 80000, miisaanka molecular-ka ee ka sarreeya ama ka hooseeyana sidoo kale waa la habeyn karaa.
Polycaprolactone waxay leedahay shuruudo heerkul hooseeya waxaana lagu qaabeyn karaa heerkul hooseeya. Waxay leedahay dhegdheg aad u fiican iyo iswaafajin wanaagsan oo leh noocyo kala duwan oo polymers ah. Astaamaheeda ugu soo jiidashada badan waa mid aan sun ahayn oo aan baaba'ayn karin. Si sax ah ayay u tahay astaamaha sare ee si weyn loogu isticmaalo meelo kala duwan, gaar ahaan caafimaadka. Aan eegno sifooyinka PCL?

Ka dib markii aan fahamnay astaamaha polycaprolactone ee kor ku xusan, waxaan soo gaarnay su'aasha aan dhammaanteen ka walaacsannahay. Taasi waa, maxaa loo isticmaali karaa polycaprolactone?
Maxaa loo isticmaali karaa polycaprolactone?
1. Dhinacyada caafimaadka
Waxaa loo isticmaali karaa tolmo qalliinka dhexdiisa ah, waxaana nuugi kara jidhka bini'aadamka. Waxa kale oo loo isticmaali karaa kabadaha lafaha, faashad resin ah, daabacaadda 3D, iyo dhinacyo kale. Intaa waxaa dheer, waa maaddada ugu muhiimsan ee "Maiden Needle".
2. Beerta resin-ka Polyurethane
Dhinaca resin-ka polyurethane, waxaa loo isticmaali karaa dahaarka, khad, dhejisyada dhalaala kulul, dhejisyada dharka aan tolnayn, qalabka kabaha, dhejisyada qaab-dhismeedka, iwm. Inta badan dahaarka waxaa loo isticmaalaa sidii rinjiyeynta baabuurta, dahaarka dusha sare, iyo dahaarka qalabka dhismaha ee kala duwan. Sababtoo ah iska caabbinta kulaylka oo wanaagsan, iska caabbinta iftiinka, iyo iska caabbinta gabowga, waxaa sidoo kale si weyn loogu isticmaalaa maqaar macmal ah.
3. Qalabka baakadaha cuntada
Sababtoo ah burburkiisa awgeed, polycaprolactone waxaa sidoo kale loo isticmaali karaa filimada qaabaynta afuufida iyo sanduuqyada baakadaha cuntada. Sababtoo ah saameynteeda cajiibka ah ee iska caabbinta kulaylka, waxaa loo isticmaali karaa sanduuqyo baakado ah, kuwaas oo aan kaliya ilaalinayn deegaanka, laakiin sidoo kale hubinaya badbaadada.
4. Goobo kale
Moodooyinka gacanta lagu sameeyay, midabeeyayaasha dabiiciga ah, dahaarka budada, wax ka beddelka balaastikada, iwm., ayaa sidoo kale loo isticmaali karaa dhejisyada.
Waa maxay rajada laga qabo polycaprolactone?
In kasta oo polycaprolactone si weyn loo isticmaalo, haddana rajadiisa horumarineed sidoo kale waa arrin muhiim ah oo walaac leh. Marka hore, waxaan barannay in polycaprolactone uu leeyahay astaamaha burburka dhammaystiran. Iyadoo la horumarinayo bulshada, wacyiga dadku ee ilaalinta deegaanka ayaa kordhay, isticmaalka balaastikada balaastigga ah ee baaba'ayana waa mid degdeg ah. Sidaa darteed, polycaprolactone waxay leedahay qiimo weyn oo loo isticmaalo dhinacyada caafimaadka, wax soo saarka, iyo warshadaha, iyoPCL Keliya ayaa hoggaamin kara agab badan. Iyadoo la horumarinayo tiknoolajiyada caafimaadka, tiknoolajiyada daabacaadda 3D ayaa sii kordheysa. Waxaa si caadi ah loogu isticmaalaa dhinaca caafimaadka sidii qalab naqshadaynta unugyada ah oo uu nuugi karo oo uu ka saari karo jidhka bini'aadamka. Iyada oo ah wakiil ka mid ah agabka cusub ee la sameeyay ee bayoolojiga ah, polycaprolactone waxay leedahay rajo horumarineed oo wanaagsan, baahiduna way sii kordheysaa. Waxaan rajeynayaa in maqaalkani uu ku caawin doono.
