2results about How to "Reduce surface tack" patented technology

This invention relates to the fields of fine chemicals and polymer materials technology, specifically a method for manufacturing toy adhesives. It includes steps for preparing the adhesive base material, preparing borax solution, and cross-linking molding. Polyvinyl alcohol, guar gum, methylparaben, etc., are prepared as base materials, which are then reacted with borax solution to undergo a cross-linking reaction. The core of this invention is the strict limitation of specific high-temperature ranges and constant-temperature stirring times during the base material preparation process, which promotes the complete extension and entanglement of molecular chains, constructing a dense and uniform three-dimensional network structure. This invention effectively avoids microscopic particle residue and stress concentration, achieving a significant improvement in the tensile strength, elongation at break, and resilience of the toy adhesive.

The utility model belongs to the technical field of regeneration asphalt production, specifically provide a kind of asphalt mixing building regenerative material buffer device including buffer bin, gas-collecting hood, mixing subassembly, regenerative material conveying subassembly and anti-sticking agent conveying subassembly, buffer bin is used to store hot regenerative material, gas-collecting hood is set in the top of buffer bin. Anti-sticking agent conveying subassembly is used to convey anti-sticking agent to mixing cylinder, and regenerative material conveying subassembly is used to convey heated regenerative material to mixing cylinder. Mixing cylinder is obliquely arranged, anti-sticking agent and hot regenerative material are mixed and moved downward, and finally fall into the buffer bin below from mixing outlet. The utility model is provided with mixing cylinder above buffer bin, so that anti-sticking agent and hot regenerative material are mixed uniformly in mixing cylinder, and then fall into the buffer bin below through mixing outlet. Mixing cylinder is a semi-closed space, and anti-sticking agent is not easily sucked away by gas-collecting hood, which reduces the waste of anti-sticking agent and reduces the processing burden of flue gas treatment equipment.
