Zvishandiso zvemidziyo yekurapa zvinogona kukamurwa kuita zvikamu zviviri: simbi zvinhu uye polymer zvinhu. Izvo zvinhu zvesimbi zvinhu zvakadzikama uye zvine kushivirira kwakanaka kune dzakasiyana nzira dzesterilization. Naizvozvo, kushivirira kwezvinhu zvepolymer kunowanzo kutariswa mukusarudzwa kwemaitiro esterilization. Izvo zvinowanzo shandiswa zvekurapa zvepolymer zvishandiso zvekurapa zvinonyanya polyethylene, polyvinyl chloride, polypropylene, polyester, nezvimwe, izvo zvese zvine zvinhu zvakanaka zvinogoneka kuneethylene oxide (EO)sterilization nzira.

EOis a wide-spectrum sterilant inogona kuuraya tupukanana dzakasiyana patembiricha yekamuri, kusanganisira spores, tuberculosis bacteria, mabhakitiriya, mavhairasi, fungi, nezvimwe.EOigasi risina ruvara, rinorema kudarika mhepo, uye rine hwema hweether. Kana tembiricha yadzikira pane 10.8 ℃, gasi rinonyunguduka uye rinova mvura isina ruvara inoonekera pakudziya kwakaderera. Inogona kusanganiswa nemvura mune chero chikamu uye inogona kunyungudutswa mune zvinowanzoshandiswa organic solvents. Iyo vapor pressure yeEO yakakura, saka ine simba rekupinda mukati mezvinhu zvakashongedzwa, inogona kupinda mukati meiyo micropores uye inosvika kune yakadzika chikamu chezvinhu, izvo zvinoita kuti inyatso sterilization.

Sterilization Temperature

Muethylene oxidesterilizer, kufamba kwe ethylene oxide mamorekuru kunowedzera sezvo tembiricha inokwira, izvo zvinoita kuti isvike pazvikamu zvinoenderana nekuvandudza maitiro esterilization. Nekudaro, mune chaiyo yekugadzira maitiro, tembiricha ye sterilization haigone kuwedzerwa nekusingaperi. Pamusoro pekutarisa mutengo wesimba, kuita kwemidziyo, nezvimwe, kukanganisa kwetembiricha pakuita kwechigadzirwa kunofanirwawo kutariswa. Kunyanya kupisa tembiricha kunogona kukurumidzira kuparara kwezvinhu zvepolymer, zvichikonzera zvigadzirwa zvisina kukodzera kana kupfupikiswa hupenyu hwebasa, nezvimwe.Naizvozvo, tembiricha ye ethylene oxide sterilization inowanzoita 30-60 ℃.

Relative Humidity

Mvura inobatanidzwa muethylene oxidesterilization reaction. Chete nekuona humwe hunyoro hunyoro mune inouraya ndipo panogona kuti ethylene oxide uye tupukanana zvipinde mualkylation reaction kuti zvizadzise chinangwa chesterilization. Panguva imwecheteyo, kuvepo kwemvura kunogonawo kukurumidza kukwira kwekushisa mu sterilizer uye kukurudzira kugoverwa kweyunifomu yesimba rekupisa.Hunyoro hunyoro hweethylene oxidesterilization ndeye 40% -80%.Kana yakadzikira kupfuura 30%, zviri nyore kukonzera kutadza kubereka.

Concentration

Mushure mekuona tembiricha ye sterilization uye hunyoro hwehukama, iyoethylene oxidekutarisisa uye kuita sterillization kunowanzo kuratidza yekutanga-kurongeka kinetic reaction, ndiko kuti, chiyero chekuita chinowedzera nekuwedzera kweiyo ethylene oxide concentration mune sterilizer. Zvisinei, kukura kwayo hakuna muganhu.Kana tembiricha yadarika 37°C uye ethylene oxide concentration inopfuura 884 mg/L, inopinda zero-order reaction state.,uyeethylene oxideKuisa pfungwa kune zvishoma pane maitiro ekuita.

Nguva Yekuita

Paunenge uchiita sterilization kusimbiswa, iyo hafu-kutenderera nzira inowanzo shandiswa kuona nguva yekubereka. Iyo nzira yehafu-yekutenderera inoreva kuti kana mamwe maparamendi kunze kwenguva anoramba asina kuchinjika, nguva yekuita inodimburwa nepakati munhevedzano kusvika nguva pfupi yekuti zvinhu zvakaomeswa zvisvike pakuora yawanikwa. The sterilization bvunzo inodzokororwa katatu. Kana iyo sterilization mhedzisiro inogona kuwanikwa, inogona kutariswa sehafu-kutenderera. Kuti uve nechokwadi chekuita sterilization,iyo chaiyo yesterilization nguva yakatarwa inofanira kunge iri kaviri hafu-kutenderera, asi nguva yekuita inofanirwa kuverengerwa kubva panguva yekupisa, hunyoro hunyoro,ethylene oxidekusungirirwa uye mamwe mamiriro mu sterilizer anosangana nezvinodiwa sterilization.

Packaging zvinhu

Nzira dzakasiyana dze sterilization dzine zvinodiwa zvakasiyana zvekurongedza zvinhu. Iko kuchinjika kwezvinhu zvekurongedza zvinoshandiswa kune sterilization process inofanirwa kutariswa. Zvinhu zvakanaka zvekurongedza, kunyanya zvidiki zvekurongedza zvinhu, zvine hukama zvakananga neiyo sterilization maitiro ethylene oxide. Paunenge uchisarudza zvekurongedza zvinhu, zvingangoita zvinhu zvakaita sekushivirira kwesterilization, kufema kwemhepo, uye antibacterial zvimiro zvinofanirwa kutariswa.Ethylene oxidesterilization inoda kurongedza zvinhu kuti ive neimwe mhepo permeability.
