How to use hydroxypropyl methyl cellulose to improve the performance and quality of ready-mixed mortar

First, from the quality management of ready-mixed mortar, to ensure the quality of mortar production-transport-transport-gas feed tank mortar. In particular, to solve the problem of apartheid, we must pay special attention to every link, finished goods warehouse, storage enterprise, must have mechanical measures to ensure the balance of mortar, prevent the mortar from causing a higher variance of the tail; and prevent the reliability of the tank and storage For long-term memory materials, the ready-to-mix mortar technology service center has a concrete and feasible solution to ensure a balanced mortar.

Second, the problem of premixed mortar transportation. At present, most of the bulk transportation, this mode of transportation is simple, but the receipt of materials for charging and transportation will inevitably lead to the separation of mortar. If there is no strong management skills and methods for loading and transporting, the problem of mortar segregation will be more serious. Specifically, most of the car mortar management and head length shrinkage: the driver installs the mortar installation, the bulk car back and forth on the brakes, the movement of the mortar is converted into a reciprocating fixture, and the coarse aggregate sinks. The most common laboratory technicians in our factory for mortar samples and on-site sampling, with longer sampling of sampling equipment. Because the car surface is about 30 cm powder (cement, fly ash, additive), the mortar layer is very serious. When the premixed mortar is loaded into the vehicle, the car will compress the gas into the storage tank site, and the tank will be in the field. The plate, under the action of compressed gas, the mortar in the tank is the distance that does not cause long-term flow. Let’s not talk about the design of the station tank treatment. In bulk trucks, the ready-mixed mortar itself is not uniform. In the proper proportion, the natural gas transport mortar has a large size, and the tanks have different degrees in the field of ready-mixed mortar. Layer and isolation.

Third, the company detected each tank by tracking 15 tank discharges, and each tank was interrupted 5 times, 5 times with different degrees of difference (response changes, sand, cement, blending ratio). By testing a range of technical indicators and wall tests, there are several significant differences between performance. The above are products of the same specifications and models. Because the product is more evenly sampled in the mixer, there is no delamination or segregation, but the product’s movement, processing, and storage segregation, in severe cases, the stratification exceeds the standard, which is a mortar that is prone to segregation. It is difficult to apply and harden cement mortar stratification; generally not more than 30mm; stratified through mortar is small or close to zero, although water is very strong, no segregation phenomenon, but usually the content of this mortar cementing material is too much, or fine The aggregate is fine and easy to produce shrinkage cracks, so usually the mortar layer should not be less than 10mm. Therefore, the site uses the car to fill the floor with the mortar. Once the floor is put into use, the wall is again mixed (mixed) with the shovel water.
