Polyurethane Elastomers are becoming increasingly popular in industries because of the exceptional performance in a number of applications compared to other materials. They're also used to restore petrochemicals as environmentally friendly alternatives which are also effective. The upsurge in performance comes with the challenge of a growth in tighter specifications. The dynamic and vacuum mixing technologies which are necessary for Polyurethane Elastomers are far more precise than those necessary for other materials like epoxies and silicon materials.
Two stage Versus One Stage Design
Polyurethane requires two part design for metering process to work correctly. A one step design where the different components are mixed with the curative at once, is not to effective. The main one stage system is too inconsistent as it pertains to consecutive batch to batch production. The variation is fairly high so it often doesn't meet with the threshold required for quality industrial production.
The dynamic mixing technologies used for 3d mixer Elastomers could be summarized into two categories and about 8 different types of machines. Both categories are fixed or variable ratio meters. Fixed ratio meters cannot change the ratio of the materials used unless some the main components are replaced.
Variable and Fixed Ratio Meters
With variable machines the ratio could be changed to accommodate changes over the way. The ratio is changed by adjusting a technical or electronic gauge on the equipment. Variable machines are employed by manufacturers to try different materials and get the optimum mix ratio.
You can find various kinds of meters used for both step polyurethane mixing, which is often engineered to work both as a variable or fixed ratio meter. The most common ones are check, gear, gear rod and positive rod replacement.
The choice of equipment will affect the durability of the product, the expense of production and that of these products and how easily spare parts could be manufactured. The choice of the proper vacuum mixing equipment is therefore imperative to the manufacturer and special considerations should be produced when selecting the proper equipment.
Continuous flow and Precision
The aim of the method will affect the option of the machinery used for mixing. In situations where precision is the priority, a metering technology such as for example positive rod meter is the ideal choice. Another technologies are used for consistent and uninterrupted flow of the manufacturing process. You also need to consider the durability of the system and the expense of maintaining it. Systems like the positive rod have fewer parts and will last more than other technologies.
The processing of Polyurethane Elastomers requires high degrees of precision. The mixing process is the most sensitive stage as it pertains to processing such materials. The choice of equipment, particularly meter mix machine should be achieved carefully.
