Isicelo

I-3,4'-oxydianiline Cas 2657-87-6 isetshenziswe kwifilimu ye-PI, izinto eziphakeme zokuvimbela izindiza zokuvimbela izindiza, njll

1 Dye amadayi kanye nemibala: Isetshenziswa njengommeleli wokuhlanganiswa kodayi kanye nemibala, ikakhulukazi kwizimboni zendwangu nezokuphrinta.

I-3. I-DRUCE: Ingasetshenziswa njengengxenye ekuhlanganiseni kwezindawo zezidakamizwa.

4. Ucwaningo lwamakhemikhali: I-3,4-diphenyl ether isetshenziswa ocwaningweni oluhlukahlukene lwamakhemikhali nasentuthukweni, kufaka phakathi ucwaningo lwezinhlansi ezimnandi nezinto zazo zokutholwa.

Mayelana nokuhamba

* Singahlinzeka izinhlobo ezahlukene zokuhamba ngokubheka izimfuno zamakhasimende.
* Lapho inani lincane, singathumela ngendiza noma nge-FedEx, njengeFedEx, DHL, TNT, EMS kanye nemigqa ehlukahlukene yezokuthutha yezokuthutha.
* Lapho ubungako bukhulu, singathumela ngolwandle ukuze baqokwe ethekwini.
* Ngaphandle kwalokho, futhi singanikeza ngezinsizakalo ezikhethekile ngokuya ngezidingo zamakhasimende kanye nemikhiqizo.

Ukukhokha

* Singahlinzeka ngezindlela eziningi zokukhokha kumakhasimende ethu.
* Lapho isamba sinesizotha, amaklayenti ajwayele ukukhokha nge-PayPal, Union asentshonalanga, i-ALIBABA, nezinye izinsizakalo ezifanayo.
* Lapho isamba sibalulekile, amaklayenti ngokuvamile akhokha nge-T / T, l / c lapho ethembeni, i-Alibaba, nokunye.
* Ngaphezu kwalokho, inani elandayo labathengi lizosebenzisa i-Alipay noma i-WeChat Pay ukwenza izinkokhelo.

Ukubeka

Egcinwe esitolo sokugcina esomile futhi emotweni.

1. Isitsha: Gcina esitsheni somoya ukuvikela ukungcoliswa kanye nokumunca umswakama.

2. Indawo: isitolo esitsheni endaweni epholile, eyomile, enomoya omuhle ukusuka ekukhanyeni okuqondile kwelanga kanye nemithombo yokushisa.

3. Ukushisa: Gcina izinga lokushisa elizinzile, eliphansi ngaphansi kuka-25 ° C (77 ° F) ukuvikela ukonakala.

4. Ukungalingani: Gwema ukubekelwa phansi eduze kwama-oxididing agents noma ama-acid njengoba azosabela nge-compound.

I-5. Ilebula: Faka ilebula ngokucacile iziqukathi ngegama lamakhemikhali, imininingwane yengozi, nosuku lokuthola.

I-6

Ingabe i-3,4'-oxydiline iyingozi?

Yebo, 3,4'-diphenyl ether kubhekwa njengengozi. Kuhlukaniswa njengento enobungozi ngenxa yemiphumela yayo engaba khona empilweni. Nawa amanye amaphuzu asemqoka ngezingozi zawo:

1. Ubuthi: 3,4'-diphenyl ether ingadala ukulimala uma kuncishisiwe, kukhungathekile, noma kuthathwe esikhunjeni. Kungenzeka kube lula esikhunjeni, emehlweni naseqenjini lokuphefumula.

2. I-Carcinogenicicity: Ezinye izifundo zikhombisile ukuthi ama-amoratic amines (kufaka phakathi ama-3,4'-diphenyl ether) kungenzeka abe carcinogenic. Kunconywa ukuphatha ngokuqapha futhi kunciphise ukuvezwa.

I-3. Umthelela Wezemvelo: Leli ngxenye lingabeka engcupheni impilo yasemanzini nasendaweni, ngakho-ke ukulahlwa nokwelashwa okulungile kubalulekile.

I-4. Imishini yokuzivikela (i-PPE): Lapho usebenza nge-3,4'-diphenyl ether, ngaso sonke isikhathi sebenzisa i-PPE efanele njengamagilavu, ama-goggles, nokuvikelwa kokuphefumula ukunciphisa ukubonakaliswa.

Izisombululo ngesikhathi sokuhamba

1. Ukupakishwa:

Sebenzisa iziqukathi ezifanele ezihambelana ne-3,4'-diphenyl ether. Qiniseka ukuthi iziqukathi zivalwe ngokuqinile ukuvikela ukuvuza noma ukuchitheka.
Ukufaka ilebula iziqukathi ngokucacile ngegama lamakhemikhali, uphawu lwengozi nanoma yiluphi ulwazi lokuphepha olufanele.

2. Imithetho yokuhamba:
Ukuthobela izimiso zendawo, zikazwelonke nezamazwe jikelele zokuhanjiswa kwezinto eziyingozi. Lokhu kungafaka ukuhambisana nemithetho yeZizwe Ezihlangene (i-UN) kanye nohlelo oluhlanganisiwe lomhlaba wonke lokuhlukaniswa kwezimpahla eziyingozi (i-GHS) kanye nezidingo zokulebula.

I-3. Imishini yokuzivikela (i-PPE):
Qinisekisa ukuthi abasebenzi ababandakanyeka ethethweni le-3,4'-diphenyl ether bagqoka imishini efanelekile yokuzivikela, njengamagilavu, ama-goggles kanye nezingubo zokuvikela, ukunciphisa ukuvezwa.

4. Inqubo ephuthumayo:
Ube nezinqubo zokuphendula eziphuthumayo ezikhona uma kwenzeka kuchitheka noma izingozi ngesikhathi sokuhamba. Lokhu kufaka phakathi ukuchitha ama-kits kanye nezinto zosizo lokuqala zilungele.

5. Gwema ukungahambelani:
Qinisekisa ukuthi i-3,4'-diphenyl ether ayihanjiswa ndawonye nempahla engahambelani (efana nama-oxidants aqinile noma ama-acid) ukuvikela ukusabela okuyingozi.

6. Ukulawulwa kokushisa:
Uma kunesidingo, qapha kanye nokulawula izinga lokushisa ngesikhathi sokuhamba ukuvimbela ukonakala kwesakhiwo.

7. Ukuqeqeshwa:
Qinisekisa ukuthi bonke abasebenzi ababandakanyeka ekuphatheni nasekuthuthweni kwe-3,4-diphenyl ether bathola ukuqeqeshwa okufanele ekuphatheni okuyingozi kwezinto eziphuthumayo nokuphendula okuphuthumayo.
