Abstract: Disclosed is a sintering furnace comprising a furnace body and a lifting device, wherein the furnace body comprises a furnace chamber (10) and a furnace mouth (20), the furnace chamber (10) is connected with the furnace mouth (20), wherein the sintering furnace further comprises a sealing member (30) provided at the lifting device; when the sintering furnace is in a loading or unloading condition, the sealing member (30) blocks the furnace mouth (20). When the sintering furnace is in an unloading condition, the sealing member (30) can block the furnace mouth (20), the furnace chamber (10) does not contact with the outside directly, thus the temperature in the furnace chamber (10) will not drop sharply, and the service life of the sintering furnace will be increased.

Abstract: The examples of the present application disclose a method for preparing a dental composite resin material and articles prepared therefrom, wherein the method comprises: (1) weighing in each of raw materials, including ethylenically unsaturated monomer, reinforcing fiber, filler, initiator, polymerization inhibitor and colorant; (2) mixing the weighed raw materials except reinforcing fiber, obtaining a composite resin monomer precursor; (3) impregnating the weighed reinforcing fiber into the composite resin monomer precursor for 1-5 hours, preferably 2-3 hours, at an impregnation negative pressure of less than or equal to 0.1 MPa, obtaining a composite resin monomer precursor-immersed reinforcing fiber; and (4) subjecting the composite resin monomer precursor-immersed reinforcing fiber to a solidification treatment, obtaining the dental composite resin material.
