Description

Opi bok u mIm blikowano dnia 4 grudnia 1962 r.POLSKIEJ RZECZYPOSPOLITEJ LUDOWEJ OPIS PATENTOWY Nr 46336 KI. 80 b, 6/06 KI. internat. C 04 b Wlodzimierz Skalnioinski Warszawa, Polska Halina Badoirska Warszawa, Polska Bronislawa Sklodowska-Weigt Warszawa, Polska Ediuard Szymanski Warszawa, Polska Sposób wytwarzania spoiwa gipsowo-wapiennego Patent dodatkowy dc patentu nr 45187 Patent trwa od dnia 12 kwietnia 1962 r.W opisie patentowym nr 45187 opisano sposób wytwarzania spoiwa gipsowo-wapiennego z ka¬ mienia gipsowego (CaS04-2H20), wedlug którego poddaje sie zmieleniu mieszanine kamienia gip¬ sowego, wapna palonego i wapna hydratyzowa¬ nego o stosunku ciezarowym skladników 1:0,05' — 0,2:0,02—0,10. Przemial prowadzi sie w od¬ powiednich urzadzeniach mielacych jak: mly¬ ny, kolotoki itp. Dodatek wapna palonego i hy¬ dratyzowanego oraz czas przemialu reguluje sie i ustala na podstawie uprzednich badan wstep¬ nych.Stwierdzono, ze zamiast wapna palonego a hy¬ dratyzowanego mozna stosowac popioly lotne stanowiace odpad ze spalania wegla brunatnego lub kamiennego, o ile zawieraja aktywne wap¬ no w postaci wapna palonego i czesciowo wapna hydratyzowanego w ilosci nie mniejszej niz 25C/( w przeliczeniu na CaO. Przez zmielenie kamienia gipsowgo z dodatkiem popiolów lotnych tego ro¬ dzaju uzyskuje sie spoiwo o wlasciwosciach fi¬ zycznych i mechanicznych nie ustepujacych spo¬ iwu uzyskiwanemu wedlug patentu nr 45187. Do tego celu nadaja sie np. popioly lotne ze spala-f 4 mia wegla brunatnego z okregu koninskiego. Do¬ datek popiolów lotnych musi byc regulowany w zaleznosci od zawartosci wolnego wapna w po¬ piele lotnym, przy czym wynosi on 25—50% wa¬ gowo, czyli stosunek wagowy kamienia gipsowe¬ go do popiolu lotnego poszczególnych skladni¬ ków mieszaniny spoiwowej wynosi 1,0:0,3—1,0. PLThe description of my side was blamed on December 4, 1962 of the Polish People's Republic PATENT DESCRIPTION No. 46336 KI. 80 b, 6/06 IC. boarding school. C 04 b Wlodzimierz Skalnioinski Warsaw, Poland Halina Badoirska Warsaw, Poland Bronislawa Sklodowska-Weigt Warsaw, Poland Ediuard Szymanski Warsaw, Poland Method for producing a gypsum-lime binder Additional patent dc patent No. 45187 The patent is valid from April 12, 1962 The patent description No. 45187 is described a method of producing a gypsum-lime binder from gypsum stone (CaSO4-2H2O), according to which a mixture of gypsum stone, quicklime and hydrated lime is ground with a weight ratio of components of 1: 0.05 '- 0.2: 0.02-0.10. The milling is carried out in suitable grinding devices such as: mills, chaffers, etc. The addition of quicklime and hydratable lime and the grinding time are regulated and established on the basis of previous preliminary tests. It was found that instead of quicklime and hydrated fly ash from the combustion of brown coal or hard coal may be used, provided that they contain active lime in the form of quicklime and partially hydrated lime in an amount not less than 25C / (expressed as CaO. By grinding gypsum stone with the addition of fly ash) This type of binder is obtained with physical and mechanical properties not yielding to that obtained in accordance with the patent No. 45187. For this purpose, for example, fly ash from the combustion of brown coal from the Konin District is suitable. must be regulated according to the content of free lime in the fly ash, which is 25-50% by weight, i.e. the weight ratio of the stone gypsum The amount of the fly ash of the individual components of the binder mixture is 1.0: 0.3-1.0.
