Mineral wool formula for ships and forming process

Abstract

The invention discloses a mineral wool formula for ships. The mineral wool formula comprises, by weight, 80-125 parts of silicon dioxide, 30-75 parts of magnesium oxide, 15-25 parts of zinc oxide, 16-26 parts of quartz sand, 10-17 parts of calcium chloride hexahydrate, 10-17 parts of quick lime, 2-3 parts of nanopore aerogel, 10-17 parts of expanded perlite, 13-18 parts of silica powder, 7-18 parts of bentonite and 10-13 parts of pure polyurea. Through mutual cooperation of designed silicon dioxide, calcium chloride hexahydrate, quick lime, silica powder, expanded perlite, rutile titanium dioxide, a centrifugal roller, a second motor, a first motor and a centrifugal cylinder, the problem that based on the existing mineral wool fiber centrifugal fiber forming device, in operation process, mineral wool fiber melt is attached to a centrifugal roller, the melt forms chemical fibers under the action of a centrifugal force of the centrifugal roller, and due to the fact that the centrifugal force applied to the melts by the centrifugal roller is limited, the lengths of chemical fibers are short, and the thermal inertia and heat insulation performance of mineral wool do not meet the usingrequirements is solved.

Description

technical field [0001] The invention belongs to the technical field of mineral wool production, and in particular relates to a formula and a molding process of mineral wool for ships. Background technique [0002] Mineral wool, also known as mineral wool, is an indispensable insulating building material for industry and construction. Mineral cotton and its products are light, durable, non-combustible, non-rotten, and free from insects, etc. They are excellent heat insulation and sound-absorbing materials. Cotton-like short fibers made from silicate melts, including slag wool, rock wool, glass wool and ceramic fibers, etc. Mineral wool needs to be melted with natural rock or metallurgical slag in equipment such as cupolas or pool kilns, and then used Injection method or centrifugal system.

AI Technical Summary

Problems solved by technology

[0003] Each cabin on a variety of large and small ships needs to be equipped with thermal insulation materials for internal and external heat insulation and noise insulation control according to different functions, in order to provide a comfortable living environment and working environment for the crew on board. There are still various deficiencies in the formula and molding process of mineral wool for ships that appear on the Internet, which cannot meet the needs of production

[0004] During the operation of the existing mineral wool fiber centrifugal fiber forming device and its process, most of the mineral wool fiber melt liquid is attached to the centrifugal roller, and the melt liquid is affected by the centrifugal force of the centrifugal roller. The centrifugal force exerted by body fluids is limited, resulting in short length of chemical fiber filaments, and the thermal inertia and heat insulation of mineral wool do not meet the requirements of use. Therefore, we propose a mineral wool formula and molding process for ships
