PETG yepakati bhodhorochigaba chepurasitiki chakajeka chekuchengetera chinoshandiswa kuchengetedza serum, yepakati, buffer uye mamwe mhinduro.Kuti udzivise kusvibiswa kwehutachiona hunokonzerwa nekurongedza, ese anovharirwa, uye ichi chiputiriso chinonyanya kuomeswa necobalt 60.

Sterilization inoreva kubvisa kana kuuraya mabhakitiriya ese, mavhairasi, fungi uye mamwe ma microorganisms ari paPETG yepakati bhodhoro nenzira dzakasiyana dzemuviri nemakemikari nzira, kuitira kuti isvike iyo asepsis garandi nhanho ye10-6, ndiko kuti, kuve nechokwadi chekuti mukana wekupona. hwema microorganisms ari pachinyorwa chimwe chete mumiriyoni.Nenzira iyi chete iyo ma microorganisms ari pakaputirwa anogona kudzivirirwa kubva pakukonzeresa kuwedzera kusvibiswa kwemukati.

Cobalt-60 sterilization ndiko kushandiswa kwe60Co γ-ray irradiation, ichiita pane tupukanana, zvakananga kana zvisina kunanga kuparadza nucleus yehutachiona, nekudaro kuuraya tupukanana, kutamba basa rekuuraya hutachiona uye sterilization.Imhando ye irradiation sterilization tekinoroji.Iyo γ-mwaranzi inogadzirwa neiyo radioactive isotope cobalt-60 irradiate chikafu chakaputirwa.Mukuita kwekufambiswa kwesimba uye kutamisa, simba rakasimba uye bhayoloji mhedzisiro inogadzirwa kuti izadzise chinangwa chekuuraya tumbuyu, kuuraya bhakitiriya uye kuvharira maitiro emuviri.60Co-γ-ray irradiation sterilization i "cold processing" tekinoroji, iri sterilization pane tembiricha yekamuri, γ-ray simba rakawanda, kupinza kwakasimba, mukuita sterilization panguva imwe chete, hazvizokonzerese kuwedzera kwekushisa kwezvinhu. inozivikanwawo sekuti inotonhora sterilization nzira.
