Embodiment 1
[0024] The invention provides an admixture with high concrete corrosion resistance.
[0025] The preparation method is as follows:
[0026] Step 1. Prepare materials: Prepare the required module blanks, perform CNC and EDM on the mold blanks, process the bosses on the parts of the mold blanks that need to be processed according to the design drawings, and leave machining allowances on the side walls of the bosses , or according to the design drawings, set aside a processing position at the part where the boss needs to be processed in the mold blank, and select two bumps of the same size according to the size and shape of the external thread of the plastic product;
[0027] Step 2. Machining the inner semicircle: Fix a number of bumps, use a CNC machine tool and use a ball cutter to process an inner semicircle on one end of the bump;
[0028] Step 3. Inner semicircle splicing: put the inner semicircle processed in step 2 into the jig to form an inner circle, and fix the bump o...

Abstract
The invention discloses a hot-pressing mould and a method for preparing ceramic of a thread structure with the hot-pressing mould. The method for preparing the ceramic of the thread structure comprises the steps that a needed mould roughcast is prepared, CNC and electrical discharge machining are conducted on the mould roughcast, a boss is machined on the position, needing to machine the boss, of the mould roughcast according to design paper, according to the size and shape of external threads of a plastic product, two lugs with the same size are selected, ceramic coating slurry which is dispersed evenly is evenly sprayed on threads of the lugs, the specified thickness can be sprayed on a light coating for a single time, a thick coating needs to be sprayed for two times, the thickness of each spraying is about 40-50 micrometers, and a substrate-oxide thin film-ceramic coating is formed. A mould body is manufactured by using middle carbon alloyed steel and sufficient in hardness, abrasive resistance, enough strength and toughness, the surface of the mould can be bright by spraying glass sand, the mould is not prone to being damaged, the ceramic coating is a water-based composite sol-coated ceramic particle-type coating and has the characteristics of a metal ceramic composite material, such as wear resistance and erosion resistance, and prolonging of the service life of the thread structure is facilitated.
Description
technical field [0001] The invention relates to a thread structure ceramic method, in particular to a hot pressing mold and a method for preparing thread structure ceramics. Background technique [0002] Concrete, referred to as concrete: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to the cement concrete obtained by mixing with water, additives and admixtures in a certain proportion, also called ordinary concrete. It is widely used in civil engineering. Concrete refers to a mixture made of cement (organic, inorganic or organic-inorganic composite), granular aggregates, water, chemical admixtures and mineral admixtures that need to be added in appropriate proportions, or After hardening, a composite material with an accumulation structure is formed (usually cementitious material, water, fine aggregate, coarse aggregate, when necessary, admixtures an...
