Calcium Oksaydh
lime degdega ah guud ahaan waxa ku jira lime aad u kulul, dayactirka lime ee kulaylka badan waa mid gaabis ah, haddii koollada dambaska dhagaxa ay mar kale adkaato, waxay keeni doontaa dildilaaca balaadhinta balaadhinta gabowga awgeed.Si loo baabi'iyo dhibaatadan gubasho lime, lime waa in sidoo kale "da'da" ilaa 2 toddobaad ka dib dayactirka.Qaabku waa caddaan (ama cawl, bunni, cad), amorphous, oo nuugaya biyaha iyo kaarboon laba ogsaydh hawada ka imanaya.Calcium oxide waxay la falgashaa biyo si ay u samayso kalsiyum hydroxide waxayna bixisaa kulayl.Ku milmay biyo acidic ah, oo aan lagu milmin khamriga.Maqaallada daxalka ah ee alkaline-ka ah, koodhka khatarta qaranka :95006.Lime waxay si kimikal ah ula falgashaa biyo waxayna isla markiiba kulaylaysaa heerkul ka sarreeya 100°C.

Oxalic acid
Ma nooc ka mid ah acid organic, waa wax soo saarka dheef-shiid kiimikaad ee noolaha, acid binary, si ballaaran loo qaybiyey dhirta, xayawaanka iyo fangaska, iyo in noolaha kala duwan ciyaaro hawlo kala duwan.Waxaa la ogaaday in oxalic acid ay qani ku tahay in ka badan 100 nooc oo dhir ah, gaar ahaan isbinaajka, amaranth, dabocase, purslane, tarugu, baradhada macaan iyo rhubarb.Sababtoo ah oxalic acid waxay yarayn kartaa bioavailability ee walxaha macdanta, waxaa loo tixgeliyaa inay tahay antagonist nuugista iyo isticmaalka walxaha macdanta.Anhydride keedu waa carbon sequioxide.

Polyacrylamide (Pam)
(PAM) waa homopolymer acrylamide ama polymer koobiyeeyayaal kale oo monomers ah.Polyacrylamide (PAM) waa mid ka mid ah polymers-ka biyaha ku milma ee aadka loo isticmaalo.(PAM) polyacrylamide waxaa si weyn loogu isticmaalaa ka faa'iidaysiga saliidda, samaynta waraaqaha, daaweynta biyaha, dunta, daawada, beeraha iyo warshadaha kale.Marka loo eego tirakoobyada, 37% wax soo saarka guud ee polyacrylamide (PAM) ee adduunka waxaa loo isticmaalaa daaweynta biyaha wasakhda ah, 27% warshadaha batroolka, iyo 18% warshadaha waraaqaha.

Hydrofluoric acid (HF)
Waa xal aqueous ah oo gaasta hydrogen fluoride ah, kaas oo ah hufnaan, midab lahayn, sigaar cabbitaan dareere ah oo leh ur daran.Hydrofluoric acid waa asiidh daciif ah oo aad u daxalaysa, taas oo aad u daxalaysa birta, dhalooyinka iyo walxaha silikoon ka kooban.Neefsashada uumiga ama taabashada maqaarka waxay sababi kartaa gubasho ay adagtahay in la bogsiiyo.Shaybaadhka guud ahaan waxa uu ka samaysan yahay fluorite (waxa ugu muhiimsan waa calcium fluoride) iyo sulfuric acid oo xoogaysan, kaas oo u baahan in lagu xidho dhalo caag ah laguna kaydiyo meel qabow.
