Intangiriro

Styrene, ni ibara ritagira ibara rifite impumuro idasanzwe. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya styrene:

 

Ubwiza:

1. Ubucucike bworoshye.

2. Irahindagurika mubushyuhe bwicyumba kandi ifite flash point nkeya kandi ntarengwa.

3. Ntibishobora gukoreshwa hamwe nudukoko twinshi twumuti kama kandi nibintu byingenzi kama.

 

Koresha:

1.

2. Styrene irashobora gukoreshwa mugukora ibikoresho byubukorikori nka polystirene (PS), reberi ya polystirene (SBR) na acrylonitrile-styrene copolymer.

3. Irashobora kandi gukoreshwa mugukora ibicuruzwa byimiti nka flavours hamwe namavuta yo gusiga.

 

Uburyo:

1. Styrene irashobora kuboneka hamwe na dehydrogenation mugushyushya no gukanda molekile ya Ethylene.

2. Styrene na hydrogen birashobora kandi kuboneka mugushyushya no gutobora Ethylbenzene.

 

Amakuru yumutekano:

1. Styrene irashya kandi igomba kurindwa gutwikwa nubushyuhe bwinshi.

2. Guhura nuruhu birashobora gutera uburakari na allergique, kandi hagomba gufatwa ingamba zikwiye.

3. Kumara igihe kirekire cyangwa byinshi bishobora kugira ingaruka mbi kubuzima, harimo kwangirika kwimitsi yo hagati, umwijima, nimpyiko.

4. Witondere ibidukikije bihumeka mugihe ukoresha, kandi wirinde guhumeka cyangwa gufata.

5. Kujugunya imyanda bigomba kubahiriza amategeko n'amabwiriza abigenga, kandi ntibigomba kujugunywa cyangwa gusohoka uko bishakiye.
