Intshayelelo

I-Difurfuryl disulfide (ekwabizwa ngokuba yi-difurfurylsulfur disulfide) yi-organic sulfur compound. Oku kulandelayo kukwazisa ngobume bayo, ukusetyenziswa, indlela yokuvelisa kunye nolwazi lokhuseleko:

 

Umgangatho:

- Ulwelo olungenambala ukuya kumthubi ngenkangeleko.

- Inevumba elibi.

-Inyibilika kwizinyibilikisi eziphilayo ezifana neealkoholi, ii-ethers kunye neehydrocarbons kwiqondo lobushushu begumbi.

 

Sebenzisa:

-I-Difurfuryl disulfide isetyenziswa ngokubanzi njenge-catalyst ye-foaming agents, i-adhesives, kunye ne-vulcanizing agents.

- Ingasetyenziselwa i-vulcanization ye-polyester resin, esetyenziselwa ukwandisa ukumelana nobushushu kunye namandla e-polyester resin.

- Isenokusetyenziswa kwishishini lerabha ukwenza irabha ibe vulcane ukwandisa amandla ayo kunye nokumelana nobushushu.

 

Indlela:

- I-Difurfuryl disulfide ilungiswa ngokubanzi ngokusabela kwe-ethanol kunye nesulfure.

- Imveliso inokufumaneka ngokufudumeza i-ethanol kunye nesulfure phambi kwegesi ye-inert kwaye emva koko i-distilling.

 

Ulwazi ngoKhuseleko:

-I-Difurfuryl disulfide inevumba elimnandi kwaye inokubangela ukucaphuka xa idibana nolusu, ngoko ke kufuneka kuthintelwe ukudibana ixesha elide.

- Xa usebenzisa okanye ugcina, kufuneka kuthathelwe ingqalelo ukuphepha ukudibana ne-oxidants, i-acids, kunye ne-alkalis ukukhusela ukuphendula okuyingozi.

- Inobuthi obuphantsi, kodwa kufuneka kuthathelwe ingqalelo ukuphepha ukuphefumla umphunga wayo, ukuphepha ukusetyenziswa kunye nokunxibelelana kwamehlo kunye neembrane ze-mucous.

- Landela uqheliselo olululo lwaselabhoratri kwaye unxibe izixhobo ezifanelekileyo zokuzikhusela ezinje ngeeglavu kunye nezibuko xa uphethe idifurfuryl disulfide.

- Xa ulahla inkunkuma, kufuneka ilahlwe ngokuhambelana nemimiselo yendawo yendawo kwaye ugweme ukuyikhupha kwindalo.
