Floor weight: The weight of the floor depends mainly on the density of its substrate. Substrate determines the stability of the floor, as well as impact resistance and other indicators, so the better the substrate, the higher the density, the heavier the floor. The common concern of consumers is the environmental performance of the floor. The first consideration when choosing a floor is the environmental protection of the product, followed by the other properties of the product, and the…

Mixing method of alkali cycle, fully demonstrated the hybrid process characteristics and production organization A, hybrid process is airtight type, so Bayer ... ... Sintering capacity between the two systems have some constraints. That is to say, the main joint point of the hybrid method: the red mud produced by the Bayer process must be balanced (consumed) by the sintering method; the seed mother liquor supplied by the sintering method to the Bayer process must satisfy the alkali output of…

the extruded aluminum bar is more and more uniform with the increase of the extrusion rate. However, when it is increased to 40 mm / s, the influence on the temperature field in the longitudinal direction will be more It can be said that there is a critical value of squeezing speed on the temperature field of spray cooling of flat aluminum extrusion profiles. The critical value is 40 mm / s at this time. If the squeezing speed is less than the critical value, The influence of the field is…
