Ethylene oxide (EO) yagara ichishandiswa mukuuraya utachiona uye kuuraya utachiona kwenguva yakareba uye ndiyo yega mushonga wemakemikari unoshandiswa mukuchenesa gasi unozivikanwa pasi rose sewakavimbika kupfuura mimwe yose. Kare,ethylene oxideYainyanya kushandiswa pakuuraya utachiona uye kuuraya utachiona mumaindasitiri. Nekuvandudzwa kwetekinoroji yemazuva ano yeindasitiri uye otomatiki uye tekinoroji yakangwara, tekinoroji yekuchenesa ethylene oxide inogona kushandiswa zvakachengeteka muzvipatara kuuraya utachiona mumidziyo yekurapa yakanyatsonaka inotya kupisa nehunyoro.

Hunhu hwe ethylene oxide

Ethylene oxidendiyo chizvarwa chechipiri chemishonga inouraya utachiona mushure me formaldehyde. Ichiri chimwe chemishonga inouraya utachiona yakanakisa inotonhora uye ndiyo inonyanya kukosha mune matekinoroji mana makuru ekuuraya utachiona pakupisa kwakaderera.

Ethylene oxide chinhu chiri nyore kushandisa epoxy. Igasi risina ruvara kana riri patembiricha yemumba uye pakumanikidzwa. Rinorema kupfuura mhepo uye rine hwema hwe ether hunonhuhwirira. Ethylene oxide inobvira uye inoputika. Kana mhepo iine 3% kusvika 80%.ethylene oxide, gasi rakasanganiswa rinoputika rinogadzirwa, rinopisa kana kuputika kana rakaiswa mumoto wakavhurika. Kuwanda kwe ethylene oxide kunowanzoshandiswa pakuuraya utachiona nekuuraya utachiona i400 kusvika 800 mg/L, iyo iri muhuwandu hwehuwandu hunogona kutsva uye hunoputika mumhepo, saka inofanira kushandiswa nekungwarira.

Ethylene oxide inogona kusanganiswa nemagasi asina simba akadai sekabhoni dhayiokisaidhimuchiyero che1:9 kugadzira musanganiswa usingaputike, izvo zvakachengeteka pakuuraya utachiona uye kuvhiyiwa.Ethylene oxideinogona kuita polymerization, asi kazhinji polymerization inononoka uye inonyanya kuitika muchimiro chemvura. Mumusanganiswa we ethylene oxide ne carbon dioxide kana fluorinated hydrocarbons, polymerization inoitika zvishoma nezvishoma uye ma polymer akasimba haawanzo putika.

Nheyo yeEthylene Oxide Sterilization

1. Alkylation

Maitiro ekuita kweethylene oxideMukuuraya tupukanana twakasiyana-siyana, kunyanya alkylation. Nzvimbo dzinoshanda ndisulfhydryl (-SH), amino (-NH2), hydroxyl (-COOH) uye hydroxyl (-OH) mumapuroteni nemanucleic acid molecules. Ethylene oxide inogona kukonzera kuti mapoka aya aite alkylation reactions, zvichiita kuti macromolecules aya epamuviri etupukanana asashande, nokudaro achiuraya tupukanana.

2. Dzimai basa rema enzymes ehupenyu

Ethylene oxide inogona kumisa mashandiro ema enzymes akasiyana-siyana etupukanana tudiki, senge phosphate dehydrogenase, cholinesterase nedzimwe oxidases, zvichitadzisa kupedzwa kwemaitiro akajairwa etupukanana uye zvichikonzera kufa kwatwo.

3. Kuuraya tupukanana

Zvese zviri zviviriethylene oxidemvura negasi zvine simba guru rekuuraya utachiona. Kana tichienzanisa, simba rekuuraya utachiona hwegasi rakasimba, uye gasi racho rinowanzoshandiswa mukuuraya utachiona nekuuraya utachiona.

Ethylene oxide mushonga unoshanda zvikuru unouraya uye unomisa kupararira kwemabhakitiriya, zvipembenene zvebhakitiriya, fungi, nemavhairasi. Kana ethylene oxide ikasangana nezvipembenene, asi zvipembenene zvine mvura yakakwana, maitiro ari pakati peethylene oxide nezvipembenene anowanzo kuve maitiro ekutanga. Dose inomisa kupararira kwezvipembenene zvakamera, iyo reaction curve imutsara wakatwasuka pane semi-logarithmic value.

Mhando dzekushandiswa kwe ethylene oxide sterilization

Ethylene oxideHaikuvadzi zvinhu zvakacheneswa uye ine simba rekupinda. Zvinhu zvakawanda zvisina kukodzera kucheneswa nenzira dzakawanda zvinogona kucheneswa uye kucheneswa ne ethylene oxide. Inogona kushandiswa pakucheneswa kwezvinhu zvesimbi, ma endoscope, ma dialyzers uye zvishandiso zvekurapa zvinoraswa, kucheneswa uye kucheneswa kwemachira akasiyana-siyana mumaindasitiri, zvigadzirwa zvepurasitiki, uye kucheneswa kwezvinhu munzvimbo dzine chirwere chinotapukira (senge machira emakemikari fiber, dehwe, bepa, magwaro, uye mifananidzo yemafuta).

Zvinhu zvinokanganisa mhedzisiro yekubvisa utachionaethylene oxide

Kushanda kwe ethylene oxide mukuuraya utachiona kunokonzerwa nezvinhu zvakawanda. Kuti iwane kushanda kwakanakisa kwekuuraya utachiona, chete nekudzora zvinhu zvakasiyana-siyana zvinobudirira ndiyo nzira yakanakisisa yekuuraya utachiona uye kuzadzisa chinangwa chayo chekuuraya utachiona uye kubvisa utachiona. Zvinhu zvikuru zvinokanganisa kushanda kwekuuraya utachiona ndeizvi: kuwanda kwemasero, tembiricha, hunyoro, nguva yekushanda, nezvimwewo.
