Polycaprolactone yog dab tsi?
Polycaprolactone, abbreviated li PCL, yog ib tug semi crystalline polymer thiab ib tug kiag li degradable khoom. Polycaprolactone tuaj yeem muab faib ua qib tshuaj thiab qib kev lag luam hauv daim ntawv ntawm hmoov, hais, thiab microspheres. Cov pa hnyav molecular yog 60000 thiab 80000, thiab siab dua lossis qis dua molecular hnyav kuj tuaj yeem hloov kho.
Polycaprolactone muaj qhov xav tau ntawm qhov kub thiab txias thiab tuaj yeem ua pwm ntawm qhov kub thiab txias. Nws muaj adhesion zoo heev thiab zoo compatibility nrog ntau yam polymers. Nws qhov ntxim nyiam tshaj plaws yog tsis muaj tshuaj lom thiab biodegradable. Nws yog qhov tseeb vim nws cov yam ntxwv siab uas nws tau siv dav hauv ntau yam, tshwj xeeb tshaj yog nyob rau hauv kev kho mob. Cia peb saib cov khoom ntawm PCL?

Tom qab nkag siab 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 tuaj yeem siv rau dab tsi?
Polycaprolactone tuaj yeem siv rau dab tsi?
1. Kev kho mob yam
Nws tuaj yeem siv rau suture hauv kev phais thiab tuaj yeem nqus tau los ntawm tib neeg lub cev. Nws tseem tuaj yeem siv rau hauv orthopedic splints, resin bandages, 3D luam ntawv, thiab lwm yam. Tsis tas li ntawd, nws tseem yog cov khoom tseem ceeb ntawm "Maiden Needle".
2. Polyurethane resin teb
Nyob rau hauv lub tshav pob ntawm polyurethane resin, nws yuav siv tau nyob rau hauv coatings, inks, kub yaj adhesives, uas tsis yog-woven npuag adhesives, cov ntaub ntawv khau, structural adhesives, thiab lwm yam. Feem ntau cov coatings yog siv raws li automotive primers, nto txheej, thiab ntau yam ntaub ntawv tsev coatings. Vim nws zoo dua kub tsis kam, lub teeb tsis kam, thiab kev laus tsis kam, nws kuj yog siv dav hauv cov tawv tawv.
3. Cov khoom ntim khoom noj
Vim nws degradability, polycaprolactone kuj tseem siv tau rau hauv tshuab molding films thiab cov thawv ntim khoom noj. Vim nws cov txiaj ntsig zoo kawg nkaus ua kom sov, nws tuaj yeem siv los ua cov thawv ntim khoom, uas tsis tsuas yog tiv thaiv ib puag ncig, tab sis kuj ua kom muaj kev nyab xeeb.
4. Lwm qhov chaw
Cov qauv xuas tes ua, cov xim organic, hmoov txheej, kev hloov kho yas, thiab lwm yam, kuj tuaj yeem siv rau hauv cov nplaum.
Lub zeem muag ntawm polycaprolactone yog dab tsi?
Txawm hais tias polycaprolactone tau siv dav, nws txoj kev vam meej 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 degradation tiav. Nrog rau txoj kev loj hlob ntawm tib neeg, tib neeg txoj kev paub txog kev tiv thaiv ib puag ncig tau nce, thiab kev siv cov khoom siv biodegradable yog ceev heev. Yog li, polycaprolactone muaj txiaj ntsig zoo siv hauv kev kho mob, kev tsim khoom, thiab kev lag luam, thiabPCL Ib leeg tuaj yeem ua tus thawj coj hauv ntau cov ntaub ntawv. Nrog rau kev nce qib ntawm kev kho mob thev naus laus zis, 3D tshuab luam ntawv tau dhau los ua neeg paub tab. Nws yog feem ntau siv hauv kev kho mob raws li cov ntaub so ntswg engineering scaffold khoom uas tuaj yeem nqus tau thiab tawm los ntawm tib neeg lub cev. Raws li tus neeg sawv cev ntawm cov ntaub ntawv tsim tawm tshiab biodegradable, polycaprolactone muaj txoj kev loj hlob zoo, thiab qhov kev thov yuav nce ntxiv. Kuv vam tias tsab xov xwm no yuav pab tau koj.
