Method and material to form a cast from gypsum
InactiveUS20080081317A1High dimensional accuracyEasy to separateImpression capsDental articulatorsArtificial EyesProsthesis
A method is disclosed for forming an accurate stone cast from an impression of a body region, used for the purpose of prosthetic fabrication, such as dental crowns and artificial eyes and hearing aids. The initial step with this unique method is to first acquire a suitable amount of dental stone catalyst. One type of a suitable stone catalyst is calcium sulfate dihydrate. The dental stone catalyst is engaged onto the internal surface of the impression. This catalyst, placed in the area between impression material and stone, will act to hasten the initial setting of wet, mixed dental stone that is in closest proximity to the impression. The result is a stratified set of the stone. Setting of the wet, mixed dental stone occurs first at the impression / stone interface. The mixed stone better resists distortion upon setting and the resultant set stone cast is more accurate.

The invention relates to a Zn modified multi-level pore HZSM-5 catalyst, a NaOH solution is used for alkali treatment of HZSM-5 molecular sieve to prepare the HZSM-5 (AT), the the HZSM-5 (AT) is mixed with binder pseudo-boehmite mixed stone and roasted to obtain industrial catalyst HZSM-5 (A-T) + A, and finally Zn (NO3) 2 modification of the HZSM-5 (A-T) + A is performed by equivalent-volume impregnation method to obtain Zn / (HZSM-5 (A-T) + A). The alkali modified industrial catalyst is used in liquefied gas aromatization reaction, due to the formation of a small amount of mesopores, the stability is improved; and after combination of alkali modification and Zn modification, the stability is improved, at the same time due to the existence of proper amount of Zn-L medium-strong acid center, he synergetic catalysis effect of B and L acid and strong and weak acids can be improved, splitting action of strong B acid and the generation of C9 + in liquid aromatic hydrocarbons can be reduced, and the BTEX selectivity can be improved.
