Rockwool cubes come in many different sizes. They all have holes in them to allow for starter cubes to be placed in them. They are sold by the strip or by the case. The 4" x 4" x 4" and the 6" x 6" x 6" are the most popular for growing plants to full term. The smaller blocks are generally used as a supplemental growing medium (placed in grow rocks, on a slab or directly into a hydroponic system

Q:What are common house thermal insulation materials?: Mineral wool. Rock wool and its productsMineral wool is the industrial waste slag as main raw materials by melting, cotton like insulation material made by injection method and centrifugal method: cotton is a natural rock as raw material is made of mineral wool. The commonly used rock such as Xuan Wuyan, diabase, amphibolite etc..Mineral wool characteristics: mineral cotton and products is a high-quality insulation materials, has more than 100 years of production and application history. The utility model has the advantages of light weight, heat preservation, heat insulation, sound absorption, good chemical stability, no burning and corrosion resistance, abundant raw material sources and low cost:Main use of mineral cotton: its products are mainly used in the walls of dry buildings, roof, ceiling and other insulation, insulation and sound absorption, but also made of waterproof felt and pipe sleeve.

Q:What are the differences between slag wool and rock wool?: Rock wool and slag wool, chemical composition and acidity coefficient comparison in our country, the main raw material for blast furnace slag slag cotton general or other metallurgical slag, the main raw material for rock wool basalt or diabase, the chemical composition of the differences between them are larger (

Q:What are the types of insulation materials used in pipes and equipment?: Glass wool is a fibrous material made from the melting of glass or crushed glass. It consists of two kinds of short cotton and superfine cotton.Features: glass wool can maintain good insulation performance under high temperature and low temperature; has good elastic restoring force; has good acoustic performance of acoustic noise. Have good sound-absorbing effect; good chemical stability, no aging performance unchanged, thickness, density and shape can be processed according to user requirements.Main applications: short cotton is mainly made of glass wool felt and felt. It is used for heat insulation and sound insulation of buildings, heat preservation and sound insulation of ventilation and air conditioning equipment. Superfine cotton master

Q:The water heater for what the security hole tube: Asbestos exposure to the skin for a long time, harmful to the skin, eating into the body harmful. Pack on the exhaust pipe, do not move it, there is no harm.

Q:Is the calorimeter for building materials calorific value?: Calorific value calorimeter for building materials is used to determine the calorific value of building combustible materials such as stone, wood, concrete, and even dispersed mineral wool and polymers.In the standard set / group under the condition of oxygen nitrogen calorimeter specimen is placed in a certain quality of a constant volume, in order to test the temperature rise test as the foundation, considering all the heat loss and latent heat of vaporization, heat of combustion calculation sample.

Q:What are the differences and prices between rock wool board and mineral wool board?: The habit of speaking, usually will use slag as the main raw materials to produce products known as mineral wool, and the use of natural rocks such as basalt or diabase as the main raw material for the production of a product called rock wool;

Q:What are the advantages of inorganic fiber spraying in construction engineering?: Inorganic fiber spraying is a new type of environmentally friendly architectural coatings, mainly composed of inorganic fiber and water-based adhesive composition, by mixing by air pressure pump for spraying, spraying and atomized water mixed to form coating on the substrate to protect. The coating can meet the requirements of sound absorption, thermal insulation and fire protection.

Q:What is the heat preservation material?: In accordance with applicable temperature range: can be divided into high temperature (700 degrees Celsius), medium temperature (1000~700 degrees Celsius) and low temperature (less than 100 degrees Celsius) three categories..According to different shapes are divided into: powder, granular, fibrous, block and other categories, but also divided into porous, mineral fiber and metal.According to different construction methods are divided into: wet wipe, filling type, lashing type, wrapped winding type, etc..

Q:How about the appearance of glass wool, mineral wool and asbestos?: Glass wool belongs to a kind of glass fiber, it is a kind of man-made inorganic fiber. Quartz, sand, limestone, dolomite and other natural ore as the main raw materials, with a number of soda ash, borax and other chemical raw materials into glass. In the melting state, by means of external force, the system is thrown into flocculent fibers, and the fibers and fibers are made of solid intersection. They are intertwined with each other and show a lot of small gaps. This gap can be considered as a pore. Therefore, the glass wool can be regarded as a porous material and has good thermal insulation and sound absorption performance.

Q:Fireproof rock wool board can be used as firewall?: You need to know what material the firewall is made of What are its standards and requirements? What's the function of it? When you know all about it, you won't take a piece of board to make a wall!
