Mawu Oyamba
Styrene, ndi madzi opanda mtundu okhala ndi fungo lonunkhira lapadera. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha styrene:
Ubwino:
1. Kachulukidwe wopepuka.
2. Imasinthasintha kutentha kwa chipinda ndipo imakhala ndi malo otsika kwambiri komanso malire a kuphulika.
3. Ndi miscible ndi zosiyanasiyana zosungunulira organic ndipo ndi zofunika kwambiri organic mankhwala.
Gwiritsani ntchito:
1. Styrene ndi mankhwala ofunika kwambiri, omwe nthawi zambiri amagwiritsidwa ntchito popanga mapulasitiki ambiri, mphira wopangira ndi ulusi.
2. Styrene ingagwiritsidwe ntchito kupanga zinthu zopangidwa monga polystyrene (PS), rabara ya polystyrene (SBR) ndi acrylonitrile-styrene copolymer.
3. Itha kugwiritsidwanso ntchito popanga zinthu zama mankhwala monga zokometsera ndi mafuta opaka mafuta.
Njira:
1. Styrene ikhoza kupezedwa ndi dehydrogenation ndi kutentha ndi kukakamiza mamolekyu a ethylene.
2. Styrene ndi haidrojeni angapezekenso ndi kutentha ndi kusweka ethylbenzene.
Zambiri Zachitetezo:
1. Styrene ndi yoyaka ndipo iyenera kutetezedwa kuti isapse ndi kutentha kwambiri.
2. Kukhudzana ndi khungu kungayambitse kuyabwa ndi kuyabwa, ndipo njira zoyenera ziyenera kuchitidwa.
3. Kuwonekera kwa nthawi yaitali kapena kwakukulu kungakhale ndi zotsatira zoipa pa thanzi, kuphatikizapo kuwonongeka kwa dongosolo lapakati la mitsempha, chiwindi, ndi impso.
4. Samalirani malo opumira mpweya mukamagwiritsa ntchito, ndipo pewani kupuma kapena kulowa.
5. Kutaya zinyalala kuyenera kutsata malamulo ndi malamulo oyenera, ndipo zisatayidwe kapena kutayidwa mwakufuna.
