Lightweight Insulation Castables
Lightweight thermal insulation castables are composed of refractory light aggregate, مسحوق, binding agent additives, إلخ. Compared with other indefinite refractory materials, the binding agent and moisture content are higher, the mobility is better, and the materials and binding agent can be selected according to the conditions of use.
It can be directly cast into the lining body and can be made into a prefabricated block by casting or vibration method. Lightweight heat insulation and heat preservation castable is easy to construct, and it is the most ideal product for the construction of alkali corrosion-resistant parts under high temperatures.
PER Refractories produces refractory castables that are widely used in high-temperature industries such as steel, يبني, والبتروكيماويات بسبب خصائصها العازلة والمقاومة للحرارة الممتازة.
Product Characteristics of Lightweight Insulating Castables
Lightweight heat-insulating and heat-preservation castable is easy to construct and is the ideal product for the construction of alkali corrosion-resistant parts under high temperatures. Good compatibility, strong adhesion, initial setting time and construction can be C for a long time, fast strength growth, strong seepage resistance, do not need acidification treatment, easy to ensure that the masonry mortar joints are dense and full, can significantly improve the airtightness of the chimney liner wall, integrality and corrosion resistance of the liner.
It is the ideal cementing material for a high chimney, high-temperature flue, and duct lining, and can also be used in acid-resistant ponds, tanks, and other acid-resistant projects in petroleum, المواد الكيميائية, non-ferrous metallurgy, وغيرها من الصناعات.
Product Classification

2. Lightweight refractory castables, bulk density of 0.4-1.0g/cm3.
3. Ultra-lightweight refractory castables, bulk density of less than 0.4g/cm3.
Product Characteristics
1. High operating temperature, excellent heat insulation, and heat preservation performance.
2. الكثافة الظاهرية الصغيرة, الموصلية الحرارية المنخفضة, reduce heat loss.
3. Good compatibility, strong adhesion.
4. مقاومة للتآكل الكيميائي, and strong resistance to acidic or alkaline gases.
5. Strong overall structure of pouring whole liner, good airtightness, and certain anti-corrosion ability.
According To The Use Of Different Temperature Classification
1. Low-temperature thermal insulation (وزن خفيف) القلاع الحرارية, the use of the temperature of 600-900 ℃.
2. Medium-temperature heat-insulating (وزن خفيف) القلاع الحرارية, using a temperature of 900-1200 ℃. 3. High-temperature heat-insulating (وزن خفيف) القلاع الحرارية, using a temperature of 600-900 ℃.
3. High-temperature heat insulation (وزن خفيف) القلاع الحرارية, استخدام درجة الحرارة> 1200 ℃.
Product use
Lightweight refractory castables have a wide range of applications in metallurgy, machinery, البتروكيماويات, electric power and building materials, and other industrial sectors of the kiln, thermal equipment, flue, and chimney lining. Lightweight refractory castables are commonly used as heat insulation and thermal insulation layer materials.
Low and medium-temperature lightweight castables are mainly used as heat-insulating lining, and cannot contact with flame. High-temperature lightweight castables are directly used for the working lining which is not in contact with the melt or solid medium in the furnace, and the working lining of various heating furnaces and heat treatment furnaces, which can greatly save energy consumption.
Points of Attention for Construction
When using insulation castables, the following points need to be paid attention to:
Mixing ratio: the mixing ratio of the castables is very important and should be precisely mastered according to the type of castables and the usage requirements. Improper mixing ratio may affect the performance and service life of the castables.
Construction method: The construction method of insulation castables can be chosen according to the specific situation. عادة, manual construction, mechanical construction, and pumping construction methods can be used. Different construction methods will affect the density and uniformity of the castables.
Maintenance: the insulation castables should be kept wet during the maintenance period, and the maintenance time is generally more than 24 ساعات. During the maintenance period, it is necessary to prevent the castables from drying too early and causing cracking.
باختصار, the selection and use of thermal insulation castables should be carried out according to specific conditions. Users should choose the type of insulation castables suitable for themselves, and pay attention to the mixing ratio, construction methods, and maintenance issues in the process of use, to ensure its excellent thermal insulation performance and service life.
