Zvinhu zvinoshandiswa mumidziyo yekurapa zvinogona kukamurwa kuita zvikamu zviviri: zvinhu zvesimbi nezvinhu zvepolymer. Hunhu hwezvinhu zvesimbi hwakagadzikana uye hune kutsungirira kwakanaka kune nzira dzakasiyana dzekubvisa tsvina. Nokudaro, kutsungirira kwezvinhu zvepolymer kunowanzo tariswa mukusarudza nzira dzekubvisa tsvina. Zvinhu zvinoshandiswa zvakanyanya zvepolymer zvemishonga yekurapa zvinonyanya kushandiswa polyethylene, polyvinyl chloride, polypropylene, polyester, nezvimwewo, zvese zvine kukwirira kwakanaka kwezvinhu.ethylene oxide (EO)nzira yekubvisa utachiona.

EOmushonga unouraya utachiona hwakasiyana-siyana patembiricha yemumba, kusanganisira spores, mabhakitiriya eTB, mabhakitiriya, mavhairasi, fungi, nezvimwewo. Patembiricha yemumba nekumanikidzwa,EOigesi isina ruvara, inorema kupfuura mhepo, uye ine hwema hwe ether hunonhuhwirira. Kana tembiricha iri pasi pe10.8℃, gasi rinonyunguduka uye rinova mvura inopenya isina ruvara patembiricha yakaderera. Rinogona kusanganiswa nemvura chero chikamu chipi zvacho uye rinogona kunyungudutswa muzvinhu zvinoshandiswa zvakanyanya. Kumanikidzwa kwemhepo yeEO kwakakura, saka ine simba guru rekupinda muzvinhu zvakacheneswa, inogona kupinda muma micropores uye kusvika pakadzika pezvinhu, izvo zvinoita kuti icheneswe zvakakwana.

Kupisa Kuchenesa

Muethylene oxidesterilizer, kufamba kwemamorekuru e-ethylene oxide kunowedzera sezvo tembiricha ichikwira, izvo zvinoita kuti isvike pazvikamu zvinoenderana uye kuvandudza sterilization effect. Zvisinei, mukugadzirwa chaiko, tembiricha yesterilization haigone kuwedzerwa nekusingaperi. Kuwedzera pakufunga nezvemutengo wesimba, mashandiro emidziyo, nezvimwewo, kukanganisa kwetembiricha pakushanda kwechigadzirwa kunofanirawo kufungwa. Tembiricha yakakwira zvakanyanya inogona kukurumidzisa kuora kwezvinhu zvepolymer, zvichikonzera zvigadzirwa zvisina kukodzera kana kupfupisa hupenyu hwebasa, nezvimwewo.Saka, tembiricha yekuchenesa ethylene oxide inowanzo kuve 30-60℃.

Hunyoro hushoma

Mvura inobatanidzwa muchirongwa ichiethylene oxidemaitiro ekuuraya utachiona. Ethylene oxide netupukanana twunogona kuita alkylation reaction chete kana paine hunyoro hwakati wandei mu sterilizer. Panguva imwe chete, kuvapo kwemvura kunogonawo kukurumidzisa kukwira kwekupisa mu sterilizer uye kukurudzira kugoverwa kwakafanana kwesimba rekupisa.Hunyoro hweethylene oxideKubvisa utachiona kuri 40%-80%.Kana iri pasi pe30%, zviri nyore kukonzera kutadza kubereka.

Kuisa pfungwa pachinhu chimwe chete

Mushure mekuona tembiricha yekuvhiyiwa uye hunyoro,ethylene oxideKuwanda kwemasero uye kushanda zvakanaka kwekubvisa utachiona kunowanzo ratidza kuti chinhu chinotanga kushanda zvakanaka, kureva kuti, mwero wekuita unowedzera nekuwedzera kwehuwandu hwe ethylene oxide mu sterilizer. Zvisinei, kukura kwayo hakusi kusingagumi.Kana tembiricha yadarika 37°C uye huwandu hwe ethylene oxide hwapfuura 884 mg/L, inopinda mumamiriro e zero-order reaction.uyeethylene oxideKuisa pfungwa kwakanyanya hakuna zvakunoita pahuwandu hwemhinduro.

Nguva Yekuita

Pakuita sterilization yekubvisa utachiona, nzira yehafu-cycle inowanzo shandiswa kuona nguva yekubvisa utachiona. Nzira yehafu-cycle inoreva kuti kana mamwe ma parameter kunze kwenguva akaramba asina kuchinja, nguva yekushanda inoderedzwa nehafu kusvika nguva pfupi yekuti zvinhu zvakabatwa utachiona zvisvike pakuva zvisina utachiona yawanikwa. Bvunzo yekubvisa utachiona inodzokororwa katatu. Kana sterilization ichigona kuwanikwa, inogona kuonekwa sehafu-cycle. Kuti uve nechokwadi chekuti sterilization inoitika,Nguva chaiyo yekuvhiyiwa inofanira kunge iri kanenge kaviri kupfuura hafu yemwedzi, asi nguva yekushanda inofanira kuverengwa kubva panguva iyo tembiricha, hunyoro,ethylene oxidehuwandu hwemvura mu sterilizer pamwe nezvimwe zvinhu zvinosangana nezvinodiwa zve sterilizer.

Zvinhu zvekurongedza

Nzira dzakasiyana dzekubvisa tsvina dzine zvinodiwa zvakasiyana pakugadzira zvinhu. Kugona kuchinjika kwezvinhu zvinoshandiswa pakugadzira tsvina kunofanira kufungwa nezvazvo. Zvinhu zvakanaka zvekurongedza, kunyanya zvinhu zvidiki zvekurongedza, zvine chekuita zvakananga nemhedzisiro yekubvisa tsvina ye ethylene oxide. Pakusarudza zvinhu zvekurongedza, zvinhu zvakaita sekushivirira kubvisa tsvina, kupindira kwemhepo, uye hunhu hwemabhakitiriya zvinofanirwa kufungwa nezvazvo.Ethylene oxideKuchenesa muviri kunoda kuti zvinhu zvekurongedza zvive nemhepo yakaringana.
