Quick-drying sand core type binder
Â
Â
The quick-drying adhesive is a normal-temperature, quick-drying adhesive that is well suited for combination mounting between complex cores after molding. At room temperature, the tensile strength can reach more than 0.4 MPa at 10 minutes, the tensile strength can reach more than 0.6 MPa at 15 minutes, the tensile strength can reach 1 MPa or more at 20 minutes, and the ultimate tensile strength can reach 4 MPa.
Product Name : Quick-drying adhesive
Product performance : This product has a milky white viscous paste and has the following unique advantages:
1. High-quality features such as fast hardening, high end-strength, and small air volume;
2. It overcomes the disadvantages of long drying time and high temperature required for curing.
3, to meet the hot core box, cold box core making process efficiency greatly improved, the timely assembly, the need to timely core, making the core assembly of a large number of time to shorten the installation to meet production needs;
4. It greatly shortens the time from core assembly to casting and greatly improves the company's casting production efficiency.
Product Description : This quick-drying adhesive research and development background:
In casting production, castings with complex structures such as internal cavities and stiffeners, or castings with a relatively large size, often require multiple sand cores to be manufactured separately, and then assembled and assembled to form an integral core and then cast; Sometimes, in order to make cores, lower cores, and other types of operations, it is also necessary to make sand cores in blocks and then install them in combination. The combined assembly of the above sand cores is mostly bonded with an adhesive. With the advent of hot core box and cold box core making process, the efficiency of core making has been greatly improved. Many core machines are often matched with the production capacity of the molding machine, which requires timely assembly and timely release of the core. time
Need to be shortened as much as possible to meet production needs.
Product Comparison : Various types of traditional adhesives currently used have more or less limitations, which are mainly manifested in:
Traditional adhesives need to be naturally dried for 4-8 hours before they can be used for casting. The production efficiency is low. At the same time, the bonding temperature is high, heating is needed, energy is wasted, and the heating and cooling process also takes a long time, which is not conducive to production efficiency. Improve; 2. Even some fast-drying adhesives have the following disadvantages:
(1) The hot-melt adhesive melts into a liquid state when heated and becomes solid again when cooled; it is heated and liquefied when used
(2) Two-component milky white glue can only be used for the bonding of foam molds and wood in solid casting, and needs to be separately packaged and supplied.
Therefore, with the improvement of casting styling and casting efficiency, there is an urgent need for a quick-drying adhesive with a shorter drying time and higher strength. Shengping series of quick-drying adhesives have emerged as the times require.
