Abstract
Przedmiotem wynalazku jest sposób wytwarzania wlóknistego kompozytu gipsowo-organicznego o wlasciwosciach izolacyjnych stanowiacego miedzy innymi nowy rodzaj welny mineralnej na bazie gipsu lub anhydrytu, w szczególnosci na bazie odpadowych gipsów chemicznych. Sposób wytwarzania wlóknistego kompozytu gipsowo-organicznego polega na sporzadzeniu roztworu kwasu siarkowego, zawierajacego od 8% do 40% objetosciowych H2SO4, i podgrzaniu tego roztworu, w zaleznosci od jego stezenia, do temperatury bliskiej temperaturze wrzenia. Do rozgrzanego roztworu dodaje sie gips w ilosci od 5 g/100 ml do 40 g/100 ml w zaleznosci od stezenia roztworu. Nastepnie do roztworu wprowadza sie organiczne zwiazki chemiczne w ilosci od 0,3% do 0,8% wzgledem masy gipsu, a powstala mieszanine reakcyjna roztwarza sie w temperaturze bliskiej temperatury wrzenia ukladu przez okres wynoszacy od 5 do 25 minut. Roztwór z uksztaltowanym stalym produktem poddaje sie procesowi filtracji, a powstaly na filtrze krystaliczny osad jest nastepnie przemywany acetonem lub odpowiednio przygotowana pluczka. Skrystalizowany osad, stanowiacy wlóknisty kompozyt gipsowy lub anhydrytowy, jest utrwalany w jednolity kompozyt wlóknisty poprzez poddanie osadu procesowi impregnacji polimerem.The subject of the invention is a method of producing a fibrous gypsum composite with insulating properties, which is, among others, a new type of mineral wool based on gypsum or anhydrite, in particular based on waste chemical gypsum. The method of producing the fibrous gypsum-organic composite consists in preparing a sulfuric acid solution containing from 8% to 40% by volume H2SO4, and heating this solution, depending on its concentration, to a temperature close to boiling point. Gypsum is added to the heated solution in an amount of 5 g / 100 ml to 40 g / 100 ml depending on the concentration of the solution. Then, 0.3 to 0.8% organic chemical compounds are introduced into the solution, based on the weight of the gypsum, and the resulting reaction mixture is dissolved at a temperature close to the boiling point of the system for a period of 5 to 25 minutes. The solution with the shaped solid product is subjected to filtration, and the crystalline precipitate formed on the filter is then washed with acetone or a properly prepared washer. The crystallized sludge, which is a fibrous gypsum or anhydrite composite, is fixed into a uniform fibrous composite by subjecting the sludge to a process of polymer impregnation.
