Cov yam ntxwv ntawm cov khoom siv ntawm cov fwj dej ntshiab
Serum hais txog cov kua daj daj daj sib cais los ntawm plasma tom qab fibrinogen thiab qee qhov coagulation yam raug tshem tawm ntawm cov ntshav tom qab cov ntshav coagulation, los yog cov ntshav los ntawm cov fibrinogen tau raug tshem tawm. Lub raj mis rau khaws cov ntshav qab zib feem ntau yog ua los ntawm cov khoom siv polyester (PET). Cov yam ntxwv ntawm cov khoom no yog dab tsi?
Qhov ntsuas kub ntawm cov ntshav feem ntau yog -5 degree rau -20 degree, thiab nws lub luag haujlwm tseem ceeb yog muab cov as-ham, cov tshuaj hormones thiab ntau yam kev loj hlob, khi cov proteins, tiv tauj-txhawb thiab loj hlob yam los tiv thaiv cov hlwb los ntawm mechanical puas, Cells hauv kab lis kev cai muab qee qhov kev tiv thaiv. Lub raj mis ua los ntawm PET muaj cov yam ntxwv hauv qab no:
1. High transparency thiab gloss zoo;
2. Cov khoom siv kho tshuab zoo, qhov cuam tshuam lub zog yog 3-5 lub sijhawm ntawm lwm cov yeeb yaj kiab, thiab folding kuj yog qhov zoo;
3. Roj kuj, roj tsis kam, dilute acid, dilute alkali, thiab cov kuab tshuaj feem ntau;
4. Zoo thaum tshav kub kub aging kuj, lub embrittlement kub yog -70 degree, thiab nws tseem muaj ib tug tej yam toughness ntawm -30 degree; PET tsis yooj yim rau hlawv, nplaim taws yog daj, thiab cov roj kub kub drips;
5, non-toxic, tasteless, zoo huv si thiab kev nyab xeeb, tuaj yeem siv ncaj qha rau kev ntim khoom noj;
6. Cov pa roj thiab dej vapor permeability tsawg, thiab nws muaj cov khoom siv roj zoo heev, dej, roj thiab tsw ntxhiab.
Cov yam ntxwv zoo heev ntawm cov khoom siv PET ua tau raws li qhov yuav tsum tau khaws cia ntawm cov ntshav. Lub raj mis no tuaj yeem siv tau rau lub sijhawm ntev ntawm cov tshuaj aqueous, xws li kab lis kev cai nruab nrab, trypsin, reagents, thiab lwm yam.
