Insulation material basically has this 3 large categories to go up from applied limits, we basically are insulation material cent inorganic kind of insulation material, organic kind of insulation material and compound model insulation material, every kinds of material has the characteristic of oneself and advantage, when specific applying, need couple is specific and real, analyse the function of every kinds of insulation material and advantage seriously. 1, organic organic insulation material has kind of insulation material compact sex effect of heat insolation of light, easy treatment, heat preservation stresses tall, quality wait for an advantage, because this is applied extensively at the domain such as building, chemical industry, but organic kind of inferior position that insulation material also has oneself, allow changeful form, ageing resistance for instance not can strong, security and stability are bad, and the easy combustion, protection that goes against opposite state environment. In addition, the difficulty of recycle of loop of organic insulation material is greater, construction difficulty is greater, integrated cost of application is higher. Organic kind insulation material basically has spray polyurethane (SPU) , crowded model gets together benzene board (XPS) , epispastic get together benzene board (EPS) and get together benzene grain. 2, inorganic kind of insulation material and organic material phase are compared, the unit weight of inorganic insulation material is opposite bigger, the effect of heat preservation heat insolation is relatively inferior, but the advantage of oneself is very much, be out of shape not easily for example and stability of function of ageing, whole, fire prevention good, lifecycle grows stability of flame retardant, structure, safety performance, cost of facilitating construction, whole is not very high, zoology environmental protection, can realize circular recycle to wait. At present the inorganic on the market kind insulation material basically has pearlite of cliff cotton, closed pore, expand pearlite, hollow Bo is changed small bead etc, be applied extensively at building the industry such as heat preservation and adornment. 3, compound model insulation material is complex profile makings is to point to with cotton of material of radiation-proof absorption of heat, cliff, it is even classics is treated crop orange stalk, can undertake harmless change processing, have heat preservation property and can come true reclaim the rubbish that use, and the hollow material that the method place such as epispastic technology develops have the aid of, effect of heat preservation of its heat insolation is idealer. Compound model the advantage that insulation material has a lot of inorganic insulation material and characteristic, be out of shape not easily for example, be able to bear or endure ageing, fire prevention causes strength of environmental pollution, heat-insulation layer not flame retardantly, easily low, facilitating construction, lifecycle grows cost of tall, whole etc, wastage of richer, the sources of energy compares the source that adds raw material low, the loop of facilitating resource and can use continuously, because this got used to a country greatly energy-saving the relevant demand that reduces a platoon, because this is on applied limits,got be extendinged effectively. But, compound kind insulation material has graph layer easy ageing, use cycle is short with integral cost more advanced blemish, because this is on integral application limits and integral performance,put in proper corrupt practice. The task of heat preservation construction is set according to the design will advocate layer insulation material, fill strong data and facing material combination become heat preservation structure. Current, craft of commonly used construction of heat preservation structure has the following 7 kinds. (Heat preservation of 1) daub law. Use adventitious insulation material (if expand pearlite) join binder and hurried to coagulate agent, according to certain burden scale, add cement agitate even, make plasticity mud group, daub arrives on facilities of heat preservation pipeline. Daub law heat preservation is a kind of traditional heat preservation structure and craft, the place that facilitates the construction that receive fork, hole that fill fill, equipment and conduit need the overhaul and all irregular by the heat preservation of heat preservation body. (Heat preservation of 2) colligation law. Colligation law heat preservation is will porous insulation material or mine fine canister of the insulation material warming plate that makes, envelope, canal or arc piece direct parcel is small go up in equipment and conduit, exterior in using 1.2? The galvanization iron wire of 2mm secures colligation. Colligation law heat preservation is the heat preservation configuration that uses extensively. (3) assembles type heat preservation. Heat preservation advocate layer material and outside covering layer all are the goods that decide model, spot construction needs to press norms perch only and try to secure, the heat preservation of general and special device is used mostly assemble structure of type heat preservation. (Heat preservation of 4) fill law. Fill law heat preservation is direct will inattentive mine fine material or stuff of poriferous grain stuff are mixed to equipment of conduit all round, reach certain close-grained level. What general boiler wears a wall to be in charge of is sealed mix with flange of adiabatic, valve expand section place is dismountable use fill law heat preservation structure of type heat preservation. (Heat preservation of 5) stickup law. Stickup law heat preservation is to use binder felt insulation stickup in metal or surface of pottery and porcelain, form adiabatic structure. This law suits the construction of fireproof fiber felt quite. (Heat preservation of 6) spray structure. Spray structure heat preservation uses special device to go to eject of insulation material of organic bubble heat insulation adiabatic face, form structure of spray heat insulation. (7) metal reflexes type heat preservation. Heat preservation of metallic reflex type uses stainless steel refractory steel foil makes multilayer hot screen, the air space of each hot screen is 1.5mm about, basically use at reducing radiation and hot to circulating heat preservation construction, apply to vibration and high temperature operating mode. Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
