Nyocha nke Usoro ịkpụzi Maka Ọnụ Ụzọ na Ohere Sealant

Dị ka akụkụ dị oke mkpa nke ihe mkpuchi ụlọ, usoro ịkpụzi ọnụ ụzọ na windo na-emetụta kpọmkwem nrapagide nke ngwaahịa ahụ, nguzogide ihu igwe na njirimara akara.

Usoro ịkpụzi ọnụ ụzọ na ihe mkpuchi windo nwere usoro anọ dị mkpa: ngwakọta akụrụngwa, nkwadebe ihe ndabere, mgbasawanye mgbakwunye, na ịkpụzi ikpeazụ. Nke mbụ, a na-atụle polymer isi (dị ka silicone, polyurethane, ma ọ bụ acrylate), ndị na-ejuputa (dịka calcium carbonate, carbon black), na ihe mgbakwunye (dị ka plasticizers na crosslinkers) na-atụle nke ọma dịka ihe nhazi chọrọ.
