Polycaprolactone yog dab tsi?
Polycaprolactone, luv ua PCL, yog ib qho semi crystalline polymer thiab yog ib yam khoom uas lwj tag. Polycaprolactone tuaj yeem muab faib ua qib tshuaj thiab qib kev lag luam hauv daim ntawv ntawm cov hmoov, cov khoom me me, thiab microspheres. Cov qhov hnyav molecular ib txwm muaj yog 60000 thiab 80000, thiab cov qhov hnyav molecular siab dua lossis qis dua kuj tuaj yeem hloov kho tau.
Polycaprolactone muaj qhov kub tsawg thiab tuaj yeem pwm tau ntawm qhov kub tsawg. Nws muaj kev nplaum zoo heev thiab sib xws zoo nrog ntau yam polymers. Nws qhov zoo tshaj plaws yog tsis muaj tshuaj lom thiab lwj tau. Vim nws cov yam ntxwv siab nws thiaj li siv dav hauv ntau qhov chaw, tshwj xeeb tshaj yog hauv kev kho mob. Cia peb saib cov yam ntxwv ntawm PCL?

Tom qab nkag siab txog cov yam ntxwv ntawm polycaprolactone saum toj no, peb tau los rau lo lus nug uas peb txhua tus txhawj xeeb txog. Ntawd yog, polycaprolactone siv tau rau dab tsi?
Polycaprolactone siv tau rau dab tsi?
1. Cov yam ntxwv kho mob
Nws siv tau rau kev xaws hauv kev phais thiab tib neeg lub cev tuaj yeem nqus tau. Nws kuj tseem siv tau rau hauv cov khoom siv orthopedic, cov ntaub qhwv resin, 3D printing, thiab lwm yam. Tsis tas li ntawd, nws tseem yog cov khoom xyaw tseem ceeb ntawm "Maiden Needle".
2. Polyurethane resin teb
Hauv kev ua cov polyurethane resin, nws tuaj yeem siv rau hauv cov tshuaj pleev xim, kua mem, cov nplaum kub yaj, cov nplaum tsis yog ntaub, cov ntaub khau, cov nplaum rau cov qauv, thiab lwm yam. Feem ntau cov tshuaj pleev xim siv ua cov tshuaj pleev xim rau tsheb, cov tshuaj pleev xim rau saum npoo av, thiab ntau yam tshuaj pleev xim rau cov khoom siv hauv tsev. Vim nws tiv taus cua sov zoo dua, tiv taus lub teeb, thiab tiv taus kev laus, nws kuj siv dav hauv cov tawv cuav.
3. Cov ntaub ntawv ntim khoom noj
Vim nws txoj kev lwj, polycaprolactone kuj tseem siv tau rau hauv cov yeeb yaj kiab tshuab pwm thiab cov thawv ntim khoom noj. Vim nws qhov kev tiv thaiv cua sov zoo kawg nkaus, nws tuaj yeem siv ua cov thawv ntim khoom, uas tsis yog tsuas yog tiv thaiv ib puag ncig xwb, tab sis kuj ua kom muaj kev nyab xeeb.
4. Lwm cov teb
Cov qauv ua tes ua, cov xim organic, cov hmoov txheej, kev hloov kho yas, thiab lwm yam, kuj siv tau rau hauv cov nplaum.
Yuav ua li cas thiaj nrhiav tau polycaprolactone?
Txawm hais tias polycaprolactone siv dav dav, nws txoj kev loj hlob kuj yog qhov teeb meem tseem ceeb ntawm kev txhawj xeeb. Ua ntej tshaj plaws, peb tau kawm tias polycaprolactone muaj cov yam ntxwv ntawm kev puas tsuaj tag nrho. Nrog rau kev txhim kho ntawm lub zej zog, tib neeg txoj kev paub txog kev tiv thaiv ib puag ncig tau nce ntxiv, thiab kev siv cov yas biodegradable yog qhov ceev. Yog li ntawd, polycaprolactone muaj txiaj ntsig zoo rau kev siv kho mob, kev tsim khoom, thiab kev lag luam, thiabPCL ib leeg tuaj yeem ua tus thawj coj hauv ntau yam khoom siv. Nrog rau kev nce qib ntawm cov thev naus laus zis kho mob, 3D luam ntawv thev naus laus zis tau dhau los ua neeg laus zuj zus. Nws feem ntau siv hauv kev kho mob ua cov ntaub so ntswg engineering scaffold khoom siv uas tuaj yeem nqus tau thiab tso tawm los ntawm tib neeg lub cev. Ua tus sawv cev ntawm cov ntaub ntawv biodegradable tshiab tsim, polycaprolactone muaj kev cia siab zoo, thiab qhov kev thov yuav nce ntxiv. Kuv vam tias tsab xov xwm no yuav pab tau rau koj.
