Calcium oxide
Kurumidza lime kazhinji ine yakawedzera kupisa lime, yakawandisa lime kugadzirisa inononoka, kana dombo dota paste rikaomesa zvakare, zvinokonzeresa kuparuka kwekuwedzera nekuda kwekuwedzera kwekuchembera.Kuti ubvise kukuvadza uku kwekupisa lime, lime inofanirawo kuva "yakwegura" kwemavhiki maviri mushure mekugadzirisa.Chimiro chakachena (kana grey, brown, white), amorphous, chinotora mvura uye carbon dioxide kubva mumhepo.Calcium oxide inopindirana nemvura kuita calcium hydroxide uye inopa kupisa.Soluble mumvura ine acidic, isinganyunguriki mudoro.Inorganic alkaline corrosive zvinyorwa, yenyika njodzi kodhi :95006.Lime inopindirana nemakemikari nemvura uye inobva yadziirwa kusvika patembiricha iri pamusoro pe100°C.

Oxalic Acid
Imhando ye organic acid, chigadzirwa chemetabolism yezvipenyu, binary acid, yakaparadzirwa zvakanyanya muzvirimwa, mhuka uye fungi, uye mune zvakasiyana zvipenyu zvinotamba mabasa akasiyana.Zvakaonekwa kuti oxalic acid yakapfuma mumhando dzinodarika zana dzezvirimwa, kunyanya sipinachi, amaranth, beet, purslane, taro, sweet potato nerhubarb.Nekuti oxalic acid inogona kuderedza bioavailability yezvicherwa zvinhu, inoonekwa seanopikisa kutorwa uye kushandiswa kwezvinhu zvicherwa.Anhydride yayo inonzi carbon sesquioxide.

Polyacrylamide (Pam)
(PAM) ihomopolymer yeacrylamide kana polymer yakasanganiswa nemamwe mamonmers.Polyacrylamide (PAM) imwe yemapolima anonyungudika emvura anoshandiswa zvakanyanya.(PAM) polyacrylamide inoshandiswa zvakanyanya mukushandiswa kwemafuta, kugadzira mapepa, kurapwa kwemvura, machira, mishonga, zvekurima uye mamwe maindasitiri.Zvinoenderana nenhamba, 37% yepasi rose polyacrylamide (PAM) kugadzirwa inoshandiswa pakuchenesa mvura yetsvina, 27% yeindasitiri yepetroleum, uye 18% yeindasitiri yemapepa.

Hydrofluoric Acid (HF)
Iaqueous solution yehydrogen fluoride gasi, inova iri pachena, isina ruvara, inosvuta mvura inoparadza ine kunhuhwirira kwakasimba.Hydrofluoric asidhi inoodza zvakanyanya isina kusimba asidhi, iyo inoparadza zvakanyanya kune simbi, girazi uye nesilicon-ine zvinhu.Kufema mweya wemhute kana kubata ganda kunogona kukonzera kupisa kunonetsa kupora.Rabhoritari inowanzo gadzirwa nefluorite (chikamu chikuru icalcium fluoride) uye yakadzika sulfuric acid, inoda kuvharirwa mubhodhoro repurasitiki uye kuchengetwa munzvimbo inotonhorera.
