Serum yog ib qho tseem ceeb hauv cov kab lis kev cai ntawm tes thiab ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev loj hlob ntawm tes.Qhov kev xaiv ntawmlub raj mis txiav txim siab seb cov ntshav tuaj yeem khaws tau zoo thiab khaws cia aseptic.

Serum hais txog lub teeb daj pob tshab kua cais tawm ntawm plasma tom qab tshem tawm ntawm fibrinogen thiab qee qhov coagulation yam tom qab cov ntshav coagulation, los yog hais txog cov ntshav uas tau raug tshem tawm ntawm fibrinogen.Feem ntau, qhov ntsuas kub yog -5 ℃ to -20 ℃.Tam sim no, PET yog cov khoom tseem ceeb ntawm cov fwj tshuaj hauv khw.

Txawm hais tias iav tuaj yeem siv tau ntau zaus, nws cov txheej txheem ntxuav thiab ua kom tsis muaj menyuam yog qhov nyuaj thiab yooj yim tawg.Yog li ntawd, cov ntaub ntawv PET nrog cov txiaj ntsig kev ua tau zoo maj mam dhau los ua thawj qhov kev xaiv rau cov fwj dej ntshiab.PET raw khoom muaj cov yam ntxwv hauv qab no:

1. transparency: PET cov khoom muaj siab transparency, tuaj yeem thaiv lub teeb ultraviolet, gloss zoo, pob tshab lub raj mis lub cev yog qhov tsim nyog rau kev soj ntsuam cov dej ntshiab hauv lub raj mis.

2. mechanical zog: qhov cuam tshuam lub zog ntawm PET yog 3 ~ 5 npaug ntawm lwm cov yeeb yaj kiab, zoo folding kuj.

3. corrosion kuj: roj kuj, roj kuj, acid kuj, alkali tsis kam, feem ntau cov kuab tshuaj.

4. Tsis tshua muaj kub tsis kam: PET embrittlement kub yog -70 ℃, ntawm -30 ℃ tseem muaj qee qhov toughness.

5. barrier: roj thiab dej vapor permeability yog tsawg, ob qho tib si zoo heev gas, dej, roj thiab tsw tsw.

6. Kev nyab xeeb: tsis muaj tshuaj lom, tsis qab, noj qab haus huv thiab nyab xeeb, tuaj yeem siv ncaj qha rau kev ntim khoom noj.

Qhov kub thiab txias tsis kam, pob tshab thiab thaiv cov khoom ntawm cov khoom siv PET ua rau nws yog ib qho khoom siv zoo rau lub raj mis ntau lawm.Nyob nruab nrab ntawm iav thiab PET ob cov ntaub ntawv, cov chaw tshawb fawb tshawb fawb, cov tuam txhab tshuaj kuj tseem nyiam rau PET cov ntaub ntawv raw.
