Intangiriro

Difurfuryl disulfide (izwi kandi nka difurfurylsulfur disulfide) ni ifumbire mvaruganda. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gukora namakuru yumutekano:

 

Ubwiza:

- Ibara ritagira ibara ryumuhondo mumiterere.

- Afite impumuro mbi.

- Gushonga mumashanyarazi nka alcool, ethers na hydrocarbone mubushyuhe bwicyumba.

 

Koresha:

- Difurfuryl disulfide ikoreshwa cyane nkumusemburo wibintu byinshi, ibifata, hamwe n’ibikoresho byangiza.

- Irashobora gukoreshwa mubirunga bya polyester resin, ikoreshwa mukwongera ubushyuhe nimbaraga za polyester resin.

- Irashobora kandi gukoreshwa mu nganda za reberi kugirango ihindure reberi kugirango yongere imbaraga hamwe nubushyuhe.

 

Uburyo:

- Difurfuryl disulfide muri rusange itegurwa nigisubizo cya Ethanol na sulfure.

- Igicuruzwa gishobora kuboneka mugushyushya Ethanol na sulfure imbere ya gaze ya inert hanyuma ukayitandukanya.

 

Amakuru yumutekano:

- Difurfuryl disulfide ifite impumuro mbi kandi irashobora gutera uburakari mugihe uhuye nuruhu, bityo rero ugomba kwirinda igihe kirekire.

- Mugihe ukoresha cyangwa ubitse, ugomba kwitondera kwirinda guhura na okiside, acide, na alkalis kugirango wirinde ingaruka mbi.

- Ifite uburozi buke, ariko hakwiye kwitabwaho kugirango wirinde guhumeka umwuka wacyo, wirinde kurya no guhura n'amaso hamwe na mucyo.

- Kurikiza imyitozo myiza ya laboratoire kandi wambare ibikoresho bikingira umuntu nka gants na gogles mugihe ukoresha disulfide difurfuryl.

- Iyo guta imyanda, igomba kujugunywa hakurikijwe amabwiriza y’ibidukikije kandi ikirinda kujugunya mu bidukikije.
