Xaiv lub gamma uas tsim nyog -ray resistant hloov PC qauv yuav tsum muaj kev txiav txim siab ntawm koob tshuaj kom tsis muaj menyuam, biocompatibility ntawv pov thawj, kev ua tau zoo, thiab ib puag ncig adaptability. Kev ruaj ntseg ntawm cov khoom yog qhov tseem ceeb tshwj xeeb hauv qhov siab - qhov kub thiab txias - ib puag ncig ntawm Wuhan.
1. Txhais cov kev xav tau ntawm daim ntawv thov thiab kev ua kom tsis muaj menyuam
Irradiation Dose: Paub meej qhov koob tshuaj gamma ray ntawm cov txheej txheem kom tsis muaj menyuam (feem ntau yog 25–50 kGy) thiab xaiv tus qauv uas txhawb nqa qhov koob tshuaj no.
Piv txwv li, Covestro RX2530 451118 tuaj yeem tiv taus 50 kGy thiab haum rau siab - koob tshuaj kom tsis muaj menyuam.
Hom kev tiv tauj: Yog tias siv rau tib neeg kev sib cuag lossis cov ntim tshuaj, yuav tsum tau xaiv ib qho kev kho mob -qib qauv ntawv pov thawj ISO 10993 thiab FDA USP Class VI.
Cov qauv pom zoo: Eastman Tritan™ 12000 (BPA-dawb, gamma{2}}ray resistant + EO dual sterilization).
2. Ua ntej cov qauv nrog cov ntawv pov thawj tiav

Qauv |
Gamma Dose |
Siv tau Scenarios |
|
Covestro RX2530 451118 |
Tsawg dua los yog sib npaug li 50 kGy |
Cov khoom siv kho mob pov tseg, cov khoom siv kub khiav |
|
Chimei PC-115P |
Tsawg dua los yog sib npaug li 50 kGy |
Hemodialyzers, ua pa valve connectors |
|
Eastman Tritan ™ 12000 |
Tsawg dua lossis sib npaug li 40 kGy |

|
Chihsin GN119 (Eastman) |
Tsawg dua los yog sib npaug li 50 kGy |
Cov raj mis kho mob, cov cuab yeej kho hniav |
Nco tseg: Ua ntej cov neeg muab khoom lag luam muab COA, MSDS, FDA zaub mov- ntawv pov thawj qib, thiab lwm yam, kom ntseeg tau tias kev ua raws cai thiab traceability.
3. Txhim kho tus qauv xaiv raws li Wuhan kev nyab xeeb
Nyob rau hauv siab - kub thiab siab - cov av noo ib puag ncig, cov ntaub ntawv yooj yim nqus dej, ua rau kev ua haujlwm tsis zoo tom qab irradiation. Cov lus pom zoo:
Xaiv qis -hygroscopic hloov PC (xws li Tritan™ series);
Ua kom qhuav ua ntej ua tiav (120℃rau 4-6 teev pom zoo);
Ua haujlwm tsim cov qauv tsim kom ruaj khov los tiv thaiv kev nkag los ntawm ya raws thiab degradation.
4. Tshawb xyuas kev ua thiab Moulding Compatibility
Kev txhaj tshuaj molding qib qauv (xws li RX2530 451118) yog qhov tsim nyog rau cov txheej txheem kub khiav, muab cov dej ntws zoo thiab txo cov kev ntxhov siab sab hauv;
For high transparency requirements, GN119 or Tritan™ are recommended, with transparency >89%, yooj yim rau kev kuaj pom;
Rau cov tshuaj tiv thaiv kab mob (xws li kev sib cuag nrog cov tshuaj tua kab mob), Eastman GN119 yog qhov zoo dua, vim nws tau raug kuaj pom tias tsis muaj deformation hauv ethanol thiab hydrogen peroxide.
