Na ua tseba hore sehlahisoa se ka holimo ha se kopane le mashala a kolobisitsoeng se fetoha samente? Ke mofuta oa samente o tla etsa hore samente e be matla le ho hana ho robeha. A re ke re hlahlobeng ka hloko kamoo calcium hydroxide e etsang mosebetsi oa eona ka samente!
Ts'ebetso ea hydrating cementitious e tlas'a taolo ea calcium zinc stabilizer bakeng sa pvc. Haeba u eketsa metsi ho samente u na le chemical reaction, e bitsoa hydration. Karabelo ena e etsa likristale tse tšoarang metsoako ea samente. hydration ena e nolofalloa ke calcium hydroxide, e etsang hore samente e thata e behe le ho thatafala kapele.
Le hoja calcium hydroxide e ntlafatsa ts'ebetso ea samente, e ntlafatsa le ho feta matla a samente le ho hanyetsa ho phunyeha. Lebaka ke hore re hloka samente e matla le e tšoarellang ho etsa meaho e tiileng joalo ka meaho, marokho le litsela. Tšebeliso ea li-Ca(OH)2 tsena ka samenteng, e lumella ntlafatso e potlakileng ea sebaka sa kaho le ho lelefatsa bophelo ba moaho.
Ehlile, mahlale a calcium glycerophosphate magnesium stearate ka konkreite e ka utloahala e omme hanyane, empa u kholoe, e ea khahla haholo. Pele ho tsohle, Ca(OH) 2 e sebetsana le likarolo tsa samente, e hlahisa liminerale tse ling tse etsang hore samente e be matla le ho tsitsa. Lits'ebetso li hlahisa boima bo tiileng bo khonang ho tšehetsa mojaro 'me bo hanyetsana le ketso ea boemo ba leholimo.
E le e 'ngoe ea liminerale tsa bohlokoa, e boetse e sebelisoa haholo indastering ea samente e nang le calcium hydroxide [7, 8]. Ke mokelikeli o ntlafatsang maqhama a motsoako oa samente. Sena se etsa hore ho be le motsoako o boreleli haholo le o tšoanang ho feta oo ho leng bonolo ho o etsa. Ka calcium hydroxide, likhoebo tsa samente li na le tebello e ntle ea nts'etsopele ea maemo a lefats'e.
E 'ngoe e nahanoang ke phello ea tikoloho tlhahisong ea samente le ts'ebeliso ea calcium stearate le calcium hydroxide. Le hoja calcium hydroxide e le ea bohlokoa bakeng sa ho etsa samente e matla le e tšoarellang, tsela eo e entsoeng ka eona ke mohloli o moholo oa carbon dioxide, khase e amehang phetohong ea tlelaemete. Ho fokotsa tšusumetso ena indasteri ea samente e ntse e batla litsela tse ling tsa ho hlahisa samente ka mokhoa o tsitsitseng le ka mokhoa o lumellanang le tikoloho.
