Hoʻolauna

ʻO ka difurfuryl disulfide (ʻike pū ʻia ʻo difurfurylsulfur disulfide) he pūhui sulfur organik. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

- He wai waihoʻoluʻu a melemele ke nānā aku.

- He ʻala ʻala.

- Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me nā ʻawaʻawa, nā ethers a me nā hydrocarbons i ka lumi wela.

 

E hoʻohana:

- Hoʻohana nui ʻia ʻo Difurfuryl disulfide ma ke ʻano he catalyst no nā mea hoʻoulu, adhesives, a me nā mea vulcanizing.

- Hiki ke hoʻohana ʻia no ka vulcanization o ka resin polyester, i hoʻohana ʻia e hoʻonui i ka pale wela a me ka ikaika o ka resin polyester.

- Hiki ke hoʻohana ʻia i loko o ka ʻoihana pāpaʻi e vulcanize i ka lāʻau e hoʻonui i kona ikaika a me ka pale wela.

 

Hanana:

- Hoʻomākaukau ʻia ʻo Difurfuryl disulfide e ka hopena o ka ethanol a me ka sulfur.

- Hiki ke loaʻa ka huahana ma ka hoʻomehana ʻana i ka ethanol a me ka sulfur i mua o kahi kinoea inert a laila hoʻoheheʻe ʻia.

 

ʻIke palekana:

- He ʻala ʻala ʻo Difurfuryl disulfide a hiki ke hoʻonāukiuki i ka wā e pili ana me ka ʻili, no laila e pale ʻia ka hoʻopili lōʻihi.

- I ka hoʻohana ʻana a mālama ʻana paha, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants, acids, a me nā alkalis e pale ai i nā hopena pōʻino.

- He haʻahaʻa kona ʻona, akā pono e mālama ʻia e pale aku i ka hoʻohu ʻana i kona mau mahu, e pale aku i ka ʻai ʻana a me ka hoʻopili ʻana me nā maka a me nā membrane mucous.

- E hahai i nā hana hoʻokolohua maikaʻi a e hoʻohana i nā lako pale pilikino kūpono e like me nā mīkina lima a me nā maka aniani i ka wā e lawelawe ai i ka difurfuryl disulfide.

- I ka wā e hoʻolei ʻia ai ka ʻōpala, pono e hoʻolei ʻia e like me nā lula kaiapuni kūloko a pale aku i ka hoʻokuʻu ʻana i loko o ke kaiapuni.
