Problems solved by technology
[0005] However, in the traditional production process of ventilating film, when calcium carbonate is added to a certain proportion, the processing performance and mechanical properties of the ventilating film will deteriorate. The coking formed in the die will affect the production stability of the breathable membrane and the quality of the breathable membrane

Abstract
The invention discloses a production system of modified heavy calcium carbonate dry powder. Compared with the prior art, the system includes a batching apparatus, a first buffer tank, a wet mill, a first screening device, a hydraulic cyclone separation system, a second screening device, a second buffer device, a centrifugal dehydrator, a drying feedback stirrer, a drying beater, a drying and beating dust removal device, a comprehensive tank, an acid-coating and modification machine, an acid-coating and modification dust removal device, a first acid-coating cloth bag filter, a second acid-coating cloth bag filter, a modified product storage tank and a modified product packaging machine. The second screening device is connected with the hydraulic cyclone separation system, the centrifugal dehydrator is connected with the second buffer device, the comprehensive tank is connected with the drying and beating dust removal device and the drying feedback stirrer, and the acid-coating and modification machine is connected with the comprehensive tank. According to the scheme, compared with the prior art, the produced modified calcium carbonate powder is excellent in quality, the processing fluidity and other comprehensive quality of the calcium carbonate material are easily improved, the production stability of gas-permeable membranes and the product quality are improved.
Description
technical field [0001] The application relates to the technical field of calcium carbonate preparation technology, and more specifically, relates to a modified heavy calcium carbonate dry powder production system. Background technique [0002] Calcium carbonate is a widely used inorganic filler, which can be widely used in industrial fields such as papermaking, rubber, building materials, coatings, inks, plastic products, cosmetics, and medicine. [0003] At present, breathable membrane materials can be bonded and laminated with knitted fabrics, woven fabrics, non-woven fabrics, etc., so that the fabrics can obtain special properties and are widely used in many fields. [0004] Among them, calcium carbonate material can be added into the breathable membrane as a breathable material, which is one of the very important components in the production and processing of the breathable membrane material. Using PE as the carrier, adding a certain proportion of calcium carbonate to f...
