The thread pitch of the thread from the root to the neck is gradually reduced, containing grooves are formed between the two side faces of adjacent thread teeth, and the opening widths of the containing grooves are smaller than the groove bottom widths. One thread is adopted, the bone bonding strength of the implant can be improved, the adhesion rate of osteoblast is improved, proliferation and differentiation of the osteoblast implant surface in the early implantation period are obviously promoted, and the planting survival rate is greatly increased.

Machine tool body made from waste glass
The invention provides a machine tool body made from waste glass. The invention aims at providing a machine tool body made from waste glass, which has the advantages of being high in stability, good in anti-vibration performance, low in coefficient of thermal expansion, high in tensile strength and compressive capacity, and the like, and can utilize the waste glass as a raw material so as to realize recycling of resources and changing waste into valuable. The machine tool body is prepared from the following raw materials in parts by weight: 70-75 parts of waste glass fragments and crushed glass sand, 8-10 parts of glass powder, 7-10 parts of epoxy resin, 1.75-2.5 parts of a curing agent, 1 part of carbon fibers, 1 part of basalt fibers, 0-1 part of bismuth, 0-1 part of antimony, 8-10 parts of silica powder and 0-10 parts of alumina powder.

The invention discloses a latent active filler composition, a solvent-free high-temperature-resistant permeation-resistant liquid polymer coating material, a coating and a preparation method thereof. The latent active filler composition takes a solid epoxy resin composition EG as a main raw material and comprises the following components in percentage by mass: 60%-70% of the solid epoxy resin composition, 10%-13% of a modified phenolic curing agent, 0%-1.5% of pigments and fillers and 20.01%-26% of other aids, the latent active filler composition is added into the formula of the coating material and used as a latent active powder filler at normal temperature, and when the temperature of a coating using working condition exceeds 100 DEG C, the latent active filler begins to slowly react and crosslink and forms a multi-layer reticular three-dimensional composite structure with a liquid normal-temperature cured coating; the glass transition temperature and crosslinking density of the whole coating are greatly improved, and the purpose of high temperature resistance is achieved through latent secondary reaction. The coating material can be used for a long time in an acid-base-salt medium at the temperature of less than or equal to 130 DEG C.
