Kiln furnace insulation material construction is to ensure kiln furnace can effect and the important segment of moving stability. Accurate construction method can improve heat preservation result not only, return the service life that can prolong kiln furnace. It is the crucial item that kiln furnace needs to notice when insulation material construction below:
1.Material preparation and quality control material option: According to the working temperature of kiln furnace and operating mode, choose proper insulation material, if pledge fireproof fiber, gently fireproof and firebrick, pouring makings. Ensure all material accord with design requirement and quality standard. Material examines: Before construction, the exterior that examines insulation material, density, coefficient of thermal conductivity, fireproof degree wait for crucial index, ensure without quality problem, wait like damaged, moisture or impurity.
2.The preparative work before construction clears tool reference plane: Before undertaking insulation material construction, ensure the cleanness of tool reference plane in kiln lining, dry, level off, cleared and all dirt, sundry with grease, in order to assure the adherent force of heat-insulation layer and construction quality. Put line fixed position: The basis designs a requirement, undertake putting line and number to the laid position of insulation material, ensure the precision of laid of the material in construction process and ply accord with design requirement.
3.Construction craft and measure are statified construction: It is in the heat-insulation layer construction with larger ply, use normally statified construction law. Every data part of one's job second laid, microscope flatness and packing want after laid every time, avoid occurrence space or break. Laid order: Normally from next upgrade, from in laid undertakes outside arriving, ensure material can chase an overlay, sealing is better. Especially to fireproof fiber blanket or plank, should build cheek by jowl when laid receive, avoid occurrence heat bridge. Secure with consolidate: In laid process, use appropriate fixed method according to stuff kind, the firmware that be like anchor, stick receive agent or bracket to wait. The material to easy displacement (be like fireproof fiber) , should special attention consolidate, the material in avoiding later period to move slides or fall off.
4.Juncture processing aperture is sealed: The juncture between insulation material should as far as possible close together, avoid to appear larger crack. If cannot avoid, should use appropriative high temperature resistant sealed material has stuff, ensure of heat-insulation layer successional with sealing. Avoid to heat up the bridge: Mix in juncture fixed all round, should adopt measure to avoid to heat up the formation of the bridge, the material ply that increases juncture point for example or the stuff stuff that make appliance has low coefficient of thermal conductivity.
5.Moistureproof measure is moistureproof processing: Insulation material be affected with damp be affected with damp should avoid in construction process, because material once moisture absorption, can reduce heat preservation performance not only, cause material damage possibly still. Construction environment should keep dry, it is especially when monsoon or damp weather construction. Grant the protection between time limit for a project: Insulation material is being carried, store and be affected with damp be affected with damp should avoid in construction process, especially hygroscopic strong data, wait like siliceous aluminous fiber. After construction ends, ensure heat-insulation layer does not suffer humidity to invade before unfinished is completely dry.
6.Safe construction safety precaution: Construction site should install necessary safe facilities, construction personnel should adorn proper individual defends equipment, wait like safety glove, guaze mask, blinkers, be in especially construction is fireproof fiber kind when material, in order to prevent fiber inspiratory or what skin contact causes is healthy problem. Fire and explosive prevention: Man-hour is applied in environment of high temperature work, answer to ask strictly to operate according to fire and explosive prevention, ensure the safety of construction tool, electric equipment is used, the safe incident that because scintilla or high temperature are caused,prevents happens.
7.Quality checks the examination between the layer: After laid of every insulation material is finished, should undertake checking, ensure construction quality accords with design requirement. Should notice whether the union between the layer is close together particularly, have do not have space or did not cover area. Whole experience closes: After heat preservation construction is finished, should undertake whole is checked and accept, examination material ply, flatness, sealing and secure firm sex, ensure heat-insulation layer is even, successive, close-grained.
8.Follow-up conserve and safeguard the first time warm up: After insulation material construction ends, of kiln furnace the first time warm up should ask to undertake by the design, need is normally slow warm up, in order to because temperature has changed,shun stuff fast and generation crackle or attaint. Regular examination and safeguard: In kiln furnace moving process, inspect the condition of heat-insulation layer regularly, if discover material falls off, attaint or ageing, answer to undertake in time repairing, in order to make sure the thermal efficiency of kiln furnace and safety move.
Through following above construction note strictly, the construction quality of insulation material can get kiln furnace be ensured effectively, promote kiln the energy-saving effect of furnace and service life thereby.
