The production process of foam concrete and building materials from it (for example, foam blocks) consists in preparing a mixture of cement binder, water and sand with the addition of special foam. Mechanically, the foam moves through the container with the mixture, allowing the bubbles to be evenly distributed throughout the volume. Chemical reactions are not required in the manufacture of this type of cellular concrete.

Manufacturers today are offered two types of equipment for feeding foam into the mixture: a mobile installation with a bar mixer and equipment based on a foam generator. It is not so easy for a novice manufacturer to decide which type of equipment to prefer, it is necessary to clearly understand all the pros and cons of these two types of installations. They differ in principle of operation, mobility, cost, consumption and productivity.

The mobile installation consists of an engine, dashboard and concrete mixer mounted on the bed. This equipment can be easily mixed around the production room, easily fit in a car trailer or on a construction pallet. The components must be loaded manually through the neck. The increasing pressure forms a foam mixture and its supply to the site is carried out by a five-meter-long hose attached to the installation under the influence of the pressure created in the mixer. Two or three people are needed to maintain the installation.

It is inexpensive, has a relatively low weight (about two hundredweight) and small dimensions. It is easy to move it around the construction site and transport it to the workshop if necessary. No special qualifications are required to work with the installation, it is extremely easy to operate, repair and maintain.

However, the mobile plant has low productivity, and with large production volumes it is difficult to obtain concrete of fixed density. It has a relatively high foaming consumption, it works only with certain types of cement and is very demanding on the foaming agent.

The equipment based on the foam generator consists of two tanks (a foaming agent in the upper one, a ready-made dry mixture in the lower one), control valves and a foam-generating pipe. The foam generator is connected to the water, a foaming agent is poured into the upper tank (it is allowed to use self-prepared). Then pressure is applied by the compressor and the foam exits through the pipe. The valves can adjust its texture.

The advantages of such equipment include high productivity when it is possible to obtain foam of stable density, work with any types of foaming agents and their relatively low consumption. This installation can work in conjunction with a plastering station, a mortar unit, and a mortar mixer. For her, cement and its brand are not so important, it makes it possible to adjust the density of foam, it is very reliable and quite easy to operate.

However, such an installation is very difficult to use as mobile equipment, and opening production with it will be more costly financially.

Thus, it is more convenient to use mobile installations for small industries and small construction. And to include the installation in the existing concrete production "on a large scale", it is preferable to get a foam generator. 테이블 게임 애호가에게는 블랙잭, 룰렛, 바카라, 포커와 같은 다양한 옵션이 있습니다. 24시간 내내 다양한 라이브 딜러 게임을 즐길 수 있는 바카라사이트 라이브 카지노 섹션도 확인해 볼 가치가 있으며, 신규 플레이어와 기존 플레이어 모두에게 푸짐한 보너스와 프로모션을 제공합니다. 신규 플레이어는 첫 입금 시 매치 보너스와 일부 슬롯 게임에 대한 무료 스핀이 포함된 웰컴 보너스 패키지를 즐길 수 있습니다.
