I-Calcium oxide
Umcako osheshayo ngokuvamile uqukethe umcako oshisisa ngokweqile, ukugcinwa komcako oshisisa ngokweqile kuhamba kancane, uma umlotha womlotha wetshe uqina futhi, uzodala ukuqhekeka ngenxa yokwanda kokuguga.Ukuze uqede lo monakalo wokushiswa komcako, umcako kufanele futhi “uguge” cishe amasonto ama-2 ngemva kokulungiswa.Umumo umhlophe (noma umpunga, onsundu, umhlophe), u-amorphous, udonsa amanzi kanye ne-carbon dioxide emoyeni.I-calcium oxide ihlangana namanzi yakhe i-calcium hydroxide futhi ikhiphe ukushisa.Incibilika emanzini ane-asidi, ayincibiliki otshwaleni.Izindatshana ezonakalisayo ze-alkaline, ikhodi yengozi kazwelonke :95006.Umcako ubhekana namakhemikhali emanzini futhi ushiselwa ngokushesha emazingeni okushisa angaphezu kuka-100°C.

I-Oxalic Acid
Iwuhlobo lwe-asidi ephilayo, ingumkhiqizo we-metabolic wezinto eziphilayo, i-asidi kanambambili, esatshalaliswa kabanzi ezitshalweni, ezilwaneni nasezikhunjini, futhi ezintweni eziphilayo ezihlukene zidlala imisebenzi eyahlukene.Kutholwe ukuthi i-oxalic acid inothile ngezinhlobo zezitshalo ezingaphezu kwekhulu, ikakhulukazi isipinashi, i-amaranth, ibhitrudi, i-purslane, i-taro, ubhatata kanye ne-rhubarb.Ngenxa yokuthi i-oxalic acid inganciphisa i-bioavailability yezakhi zamaminerali, ithathwa njengephikisana nokumuncwa kanye nokusetshenziswa kwezakhi zamaminerali.I-anhydride yayo i-carbon sesquioxide.

I-Polyacrylamide (Pam)
(PAM) iyi-homopolymer ye-acrylamide noma i-polymer ehlanganiswe namanye ama-monomer.I-Polyacrylamide (PAM) ingenye yama-polymers ancibilika emanzini asetshenziswa kakhulu.(PAM) i-polyacrylamide isetshenziswa kabanzi ekuxhashazweni kukawoyela, ekwenzeni iphepha, ekuhlanzeni amanzi, kwendwangu, kwezokwelapha, kwezolimo nakwezinye izimboni.Ngokwezibalo, u-37% womkhiqizo we-polyacrylamide (PAM) usuwonke emhlabeni usetshenziselwa ukuhlanza amanzi angcolile, u-27% embonini ye-petroleum, no-18% embonini yamaphepha.

I-Hydrofluoric Acid (HF)
Kuyisisombululo esinamanzi segesi ye-hydrogen fluoride, ewuketshezi olungenambala, olungenambala, olunukayo olunephunga elimnandi elinamandla.I-Hydrofluoric acid iyi-asidi ebuthakathaka egqwala kakhulu, egqwala kakhulu ezintweni zensimbi, ingilazi kanye ne-silicon.Ukuhogela isitimu noma ukuthinta isikhumba kungabangela ukusha okunzima ukukupholisa.Ilabhorethri ngokuvamile yenziwe nge-fluorite (ingxenye eyinhloko i-calcium fluoride) kanye ne-sulfuric acid egxilile, okudingeka ivalwe ebhodleleni lepulasitiki futhi igcinwe endaweni epholile.
