Selelekela

Difurfuryl disulfide (eo hape e tsejoang e le difurfurylsulfur disulfide) ke motsoako oa sebabole sa tlhaho. Se latelang ke selelekela sa sebopeho sa eona, ts'ebeliso, mokhoa oa tlhahiso le tlhaiso-leseling ea polokeho:

 

Boleng:

- Seelo se se senang mmala ho isa ho bosehla ka ponahalo.

- E na le monko o hlabang.

- E qhibiliha ka har'a metsoako ea tlhaho e kang joala, ethers le hydrocarbons mocheso oa kamore.

 

Sebelisa:

- Difurfuryl disulfide e sebelisoa haholo e le sesosa sa li-agent tse phophomang maeba, likhomaretsi le li-vulcanizing agents.

- E ka sebelisoa bakeng sa vulcanization ea polyester resin, e sebelisetsoang ho eketsa ho hanyetsa mocheso le matla a polyester resin.

- E ka boela ea sebelisoa indastering ea rabara ho vulcanize rabara ho eketsa matla a eona le ho hanyetsa mocheso.

 

Mokhoa:

- Difurfuryl disulfide hangata e lokisoa ke karabelo ea ethanol le sebabole.

- Sehlahisoa se ka fumanoa ka ho futhumatsa ethanol le sebabole ka pel'a khase e sa sebetseng ebe oa e tšela.

 

Lintlha tsa Tšireletseho:

- Difurfuryl disulfide e na le monko o hlabang 'me e ka baka ho teneha ha e kopana le letlalo, kahoo ho kopana nako e telele ho lokela ho qojoa.

- Ha o sebelisa kapa o boloka, tlhokomelo e lokela ho nkoa ho qoba ho kopana le li-oxidants, acid, le alkalis ho thibela liketso tse kotsi.

- E na le chefo e tlase, empa tlhokomelo e ntse e lokela ho nkoa ho qoba ho hema mouoane oa eona, ho qoba ho sebelisoa le ho kopana le mahlo le lera la mucous.

- Latela mekhoa e metle ea laboratori 'me u apare lisebelisoa tse nepahetseng tsa ts'ireletso joalo ka liatlana le likhalase ha u tšoara difurfuryl disulfide.

- Ha ho lahla litšila, ho lokela ho lahloa ho ea ka melao ea tikoloho ea sebaka seo 'me ho qoba ho e ntša tikolohong.
