1.1 Ngwakọta kemịkalụ na àgwà polymerization na ngwọta mmiri

(Potassium silicate)

Potassium silicate (K TWO O · nSiO ₂), a na-akpọkarị iko mmiri ma ọ bụ iko soluble, abụghị polymer eke mepụtara site na ngwakọta nke potassium oxide (K ABỤỌ O) na silicon dioxide (SiO Abụọ) na ọkwa okpomọkụ dị elu, sochiri mgbasa na mmiri iji mepụta oke, ngwọta alkaline.

N'adịghị ka sodium silicate, ya ọbụna karịa na mbụ dakọtara, potassium silicate na-eji ike siri ike, enwekwukwa mmiri na-eguzogide, na mbelata mmasị na effloresce, na-eme ka ọ bụrụ ihe bara uru karịsịa na ọkwa dị elu na ngwa ọpụrụiche.

Oke SiO ₂ ka K₂ O, gosiri dị ka “n” (modul), na-achịkwa ihe onwunwe nke ebe obibi: obere-modul ngwọta (n < 2.5) are highly soluble and responsive, while high-modulus systems (n > 3.0) gosi mma mmiri nguzogide na ihe nkiri-akpụ ike ma belata solubility.

N'ime ikuku mmiri, potassium silicate na-aga site na mmeghachi omume condensation siri ike, ebe silanol (Na– OH) Otu dị iche iche polymerize iji mepụta siloxane (Na– O– Na) netwọk– a usoro yiri eke mineralization.

Polymerization a dị egwu na-enyere aka ịmepụta silica gels akụkụ atọ mgbe ihicha ma ọ bụ acidification, na-eto eto ok, matrices na-alụso ọrịa ọgụ nke kemịkalụ na-ejikọta nke ọma na ihe ndị dị ka kọnkịtị, ígwè, na ceramik.

Nnukwu pH nke potassium silicate nhọrọ (na-emekarị 10– 13) na-enyere aka na mmeghachi omume ngwa ngwa na ihu igwe CO ₂ ma ọ bụ ìgwè hydroxyl elu, na-amụba mmepe nke akwa akwa silica na-adịghị edozi.

1.2 Nchekwa okpomọkụ na mgbanwe nhazi n'okpuru ọnọdụ dị oke egwu
