Calcium oxide
Laimu wofulumira nthawi zambiri amakhala ndi laimu wotenthedwa, kukonza kwa laimu kumachedwa pang'onopang'ono, ngati phulusa lamwala likawumitsanso, zingayambitse kuphulika chifukwa cha ukalamba.Kuti athetse vutoli pakuwotcha laimu, laimu ayeneranso kukhala "okalamba" kwa masabata a 2 mutakonza.Maonekedwe ake ndi oyera (kapena imvi, bulauni, oyera), amorphous, amatenga madzi ndi carbon dioxide kuchokera mumlengalenga.Calcium oxide imachita ndi madzi kupanga calcium hydroxide ndipo imatulutsa kutentha.Kusungunuka m'madzi acidic, osasungunuka mu mowa.Zolemba za inorganic alkaline corrosive code code ya ngozi :95006.Laimu amakumana ndi madzi ndipo amatenthedwa nthawi yomweyo mpaka kutentha kopitilira 100°C.

Hydrofluoric Acid (HF)
Ndi njira yamadzimadzi ya mpweya wa hydrogen fluoride, womwe ndi wowonekera, wopanda mtundu, wosuta wamadzimadzi owononga ndi fungo lamphamvu.Hydrofluoric acid ndi asidi ofooka kwambiri owononga kwambiri, omwe amawononga kwambiri zitsulo, galasi ndi zinthu zomwe zili ndi silicon.Kukoka mpweya wa nthunzi kapena kukhudzana ndi khungu kungayambitse zilonda zomwe zimakhala zovuta kuchiza.Laborator nthawi zambiri imapangidwa ndi fluorite (chigawo chachikulu ndi calcium fluoride) ndi acidity ya sulfuric acid, yomwe imafunika kusindikizidwa mu botolo lapulasitiki ndikusungidwa pamalo ozizira.

Oxalic Acid
Ndi mtundu wa asidi organic, ndi kagayidwe kachakudya cha zamoyo, bayinare asidi, ambiri kufalitsidwa mu zomera, nyama ndi bowa, ndipo mu zamoyo zosiyanasiyana zimagwira ntchito zosiyanasiyana.Zapezeka kuti asidi oxalic ali wolemera mu mitundu yoposa 100 ya zomera, makamaka sipinachi, amaranth, beet, purslane, taro, mbatata ndi rhubarb.Chifukwa oxalic acid imatha kuchepetsa bioavailability wa zinthu zamchere, imatengedwa ngati mdani pakuyamwa ndi kugwiritsa ntchito zinthu zamchere.Anhydride yake ndi carbon sesquioxide.

Polyacrylamide (Pam)
(PAM) ndi homopolymer ya acrylamide kapena polima copolymerized ndi monomers ena.Polyacrylamide (PAM) ndi imodzi mwa ma polima osungunuka m'madzi omwe amagwiritsidwa ntchito kwambiri.(PAM) Polyacrylamide imagwiritsidwa ntchito kwambiri pakugwiritsa ntchito mafuta, kupanga mapepala, kukonza madzi, nsalu, mankhwala, ulimi ndi mafakitale ena.Malinga ndi ziwerengero, 37% ya polyacrylamide (PAM) zonse zomwe zimapangidwa padziko lonse lapansi zimagwiritsidwa ntchito poyeretsa madzi onyansa, 27% pamakampani amafuta, ndi 18% pamakampani opanga mapepala.
