Hordhac

Styrene, waa dareere aan midab lahayn oo leh ur gaar ah. Kuwa soo socdaa waa hordhaca guryaha, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada ee styrene:

 

Tayada:

1. Cufnaanta fudud.

2. Wuu kacsan yahay marka uu heerkulka qolka ku jiro oo waxa uu leeyahay barta iftiimaya oo hooseeya iyo xadka qaraxa.

3. Waxay la jaanqaadi kartaa noocyo kala duwan oo dareere organic ah waana walax aad u muhiim ah.

 

Isticmaal:

1. Styrene waa walxo kiimiko ah oo ceeriin ah oo muhiim ah, oo inta badan loo isticmaalo isku dhafka tiro badan oo balaastik ah, caag synthetic iyo fiilooyinka.

2. Styrene waxaa loo isticmaali karaa in lagu sameeyo alaabta synthetic sida polystyrene (PS), polystyrene rubber (SBR) iyo acrylonitrile-styrene copolymer.

3. Waxa kale oo loo isticmaali karaa in lagu soo saaro wax soo saarka kiimikaad sida dhadhanka iyo saliidaha saliidda.

 

Habka:

1. Styrene waxaa lagu heli karaa fuuqbaxa iyadoo kululaynta iyo cadaadiska molecules ethylene.

2. Styrene iyo hydrogen waxa kale oo lagu heli karaa kulaylka iyo dildilaaca ethylbenzene.

 

Macluumaadka Badbaadada:

1. Styrene waa guban karta waana in laga ilaaliyo dabka iyo heerkulka sare.

2. Maqaarka oo la taabto waxay keeni kartaa xanaaq iyo falcelin xasaasiyadeed, waana in taxaddar ku habboon la sameeyaa.

3. Soo-gaadhista muddada-dheer ama la taaban karo waxay yeelan kartaa saamayn caafimaad oo xun, oo ay ku jiraan dhaawac soo gaadhay habka dhexe ee neerfayaasha, beerka, iyo kelyaha.

4. U fiirso jawiga hawo-qaadista markaad isticmaalayso, iskana ilaali neefsashada ama qaadashada.

5. Qashin-qaadista waa in ay u hoggaansamaan shuruucda iyo qawaaniinta khuseeya, waana in aan la daadin, lana saarin marka la doono.
