PETG lub raj mis nruab nrabyog lub thawv ntim yas pob tshab uas siv los khaws cov ntshav, nruab nrab, tsis thiab lwm yam kev daws teeb meem.Txhawm rau kom tsis txhob muaj kab mob microbial tshwm sim los ntawm kev ntim khoom, tag nrho cov ntawm lawv yog sterilized, thiab cov ntim no feem ntau yog sterilized los ntawm cobalt 60.

Sterilization txhais tau tias tshem tawm lossis tua tag nrho cov kab mob, kab mob, fungi thiab lwm yam kab mob ntawm PETG nruab nrab lub raj mis los ntawm ntau yam kev siv lub cev thiab tshuaj, kom nws tuaj yeem ncav cuag asepsis lav qib ntawm 10-6, uas yog, kom ntseeg tau tias qhov muaj sia nyob. ntawm microorganisms ntawm ib tsab xov xwm tsuas yog ib ntawm ib lab.Tsuas yog nyob rau hauv txoj kev no tuaj yeem tiv thaiv cov kab mob hauv lub ntim los ntawm kev ua kom muaj kab mob ntxiv ntawm cov khoom sab hauv.

Cobalt-60 sterilization yog siv 60Co γ-ray irradiation, ua rau cov kab mob, ncaj qha lossis ncaj qha rhuav tshem cov nucleus ntawm cov kab mob, yog li tua cov kab mob, ua lub luag haujlwm ntawm kev tua kab mob thiab ua kom tsis muaj menyuam.Nws yog ib hom irradiation sterilization technology.Cov γ-rays uas tsim los ntawm cov xov tooj cua isotope cobalt-60 irradiate cov zaub mov ntim.Nyob rau hauv cov txheej txheem ntawm lub zog kis tau tus mob thiab hloov mus, muaj zog lub cev thiab lom cov teebmeem yog tsim kom ua tiav lub hom phiaj ntawm tua kab, sterilizing kab mob thiab inhibiting physiological txheej txheem.60Co-γ-ray irradiation sterilization yog ib qho "txias ua" tshuab, nws yog sterilization ntawm chav tsev kub, γ-ray siab zog, muaj zog nkag mus rau hauv lub sterilization tib lub sij hawm, yuav tsis ua rau kom qhov kub ntawm cov khoom, kuj hu ua txias sterilization method.
