2. stands the adiabatic heat preservation of pipeline supports panel, should every set equipment to press paragraph of gripper shoe to secure bracket on 4m too, its beam overall but a bit under advocate the Bao Hou of thermal insulation, fixed bracket cannot install gripper shoe soldering or on the place of annotations, the annulus face of fixed bracket installs Xuan to answer level, the error does not exceed 10mm, choose the type that hire band to prop up panel to secure bracket, screw firm.
Bao Houchao of layer of conduit of 3. heat preservation wants arrangement when 80mm too, heat-insulating material of heat preservation of pipeline everybody buy and thin thick severe exacting press construction of engineering of blueprint of project of heat preservation of heat insolation of factory of program courtyard, boiler, thermal insulation should medley tight, one should be connected seam, 2 should be pressed seam, clearance uses stuff of siliceous aluminium cotton, thermal insulation uses 16# double stranded bundle up of fine iron wire is solid, flange piece the adiabatic heat preservation of place should go out to tear open the span that installs foundation bolt amply for nothing, the area that every hampers splash goes up (if pipeline crosses service platform place to wait) all should go up by splash azimuth air gives space, different splash goes up azimuth or different Wu should give measurable space for nothing among the layer of heat preservation conduit that corporeal spends;
Pluvial board annulus is blocked outside 4. to build a mouth to answer gadarene, the adjacent azimuth that build a mouth and pipeline (or machine equipment) gradient position is consistent; Annulus to build mouth or vicinity to take buccal length all cannot under 50mm. Galvanized iron of pipeline bent housing presses circumference of the circle outside adiabatic heat preservation 1.2 times as open the accident of makings. Open one of extremely of round circumference outside expecting beam overall is, cut a grow to full size put shake the extrude in route aircraft comes protruding muscle, the aluminium alloy that protect a canal board install Xuan to want to rely on chart stably, surface layer is whole smooth, reasonable configuration, smooth and beautiful easy.
5. advocate every cross vapour conduit 3 meters, every reach other pipeline 10 meters too the splash that the bent housing place of tall pipeline gives 20mm for nothing goes up seam, cotton of siliceous aluminous heat preservation is filled inside, a week of rope of felt of siliceous aluminous fiber tangles outside, pluvial board is blocked outside cover.
The staff member will touch 6. come up against, and the pipeline discharging steam that operates temperature to cross 50 ℃ high should begin heat preservation of partial heat insolation.
7. controls road of smooth tube bank 2 times to protect line of Xuan of Pi An tubal aluminium and line to solve neat, in order to assure beautiful and easy. The canal adds structural consolidate via needing in 400 right-and-left bent housing.
Pluvial board is blocked to stand to want to be put to joint outside 8. in darkness, bolt interval wants well-balanced and consistent.
Inorganic insulation material
What harm does the Bao Hou side aperture have to agglutinate?
1, fall in same density standard, the board ability diameter with large hole wall is very big, aperture antrum also relativity is very big, the mortar wiping a face that Fu sucks inside eyelet is bigger, in other words the board ability of same norms model and the surface of the mortar that wipe a face expand, board ability and metope agglutinate character are stronger, solidder.
2, put among heat preservation thermal insulation board and metope having metabolic distinction, when the Kong Bian when heat preservation thermal insulation board is thinner, of metope be out of shape the crustal stress that cause can cause Kong Bian to split, cause thereby sticky stick strike of air of metope giving or empty to stick and even fall down.
Essence of basis of thermal insulation board of poriferous structure heat preservation allows sulfur aluminium acerbity salt operate diametical dimension and the Bao Hou by the side of aperture and its compressive strength, the agglutinate that raised raw material is characteristic, board ability is sticky on the other hand after sticking a wall to go up, compressive strength can promote again, man-hour is applied in the project board ability is sticky stick after undertaking, maintain of course 3-7 day, of heat preservation thermal insulation board and metope be out of shape difference of distinction, compressive strength shrinks at least, making the photograph dissolve sex of metope and heat preservation thermal insulation board has been arrived at is, the whole process of gradual change color that retained metope and compressive strength of heat preservation heat-insulating material.
Insulation material of energy-saving building inorganic is technical experience summary
2, why general silicate board use in heat preservation of the heat insolation inside wall body only?
Outside wall heat preservation
1, general aluminous silicate is lukewarm board because the diameter is small, hole wall is thin and metope is sticky after sticking because crustal stress is different cause sticky stick metope giving empty beat and fission; are sticky the metope air strike that the dust that go up cannot eliminate the Yi Bancai when sticking to cause empty to stick and give cannot operate otherwise of moisture content of; raw material too, if apply,be in wall body, its safety factor makes a person can care, if also want outside hang software floor tile, so more without security but abide.
3, why can thermal insulation board of poriferous structure heat preservation use sulfur aluminium acerbity salt on project of project of building heat preservation?
Thermal insulation board of poriferous structure heat preservation has sulfur aluminium acerbity salt general silicate board advantage, handled further again handle the issue of of all kinds bottleneck in building project of heat preservation project.
First sulfur aluminium acerbity salt is poriferous of the Yan Ke of classics of dimension of eyelet of small orifice plate of thermal insulation board of structural heat preservation operate, its stick the heat preservation heat-insulating material of horniness of comparative and general mineral and thermal insulation board of organic chemistry heat preservation receive practical effect stronger, beat a state without metope sky, systematic software resists negative atmospheric pressure (absorption affinity) working capability is stronger.
Take second place, page of classics of all previous of surface layer of thermal insulation board of poriferous structure heat preservation solves sulfur aluminium acerbity salt, surface layer does not have grey layer,
Once more, via the water glass of raw material abhor of metallic finishing cotton is led tall, give leakage state not easily.
Eventually, sulfur aluminium acerbity salt is poriferous the metallic finishing of thermal insulation board of structural heat preservation is technical with enclosed ministry Kong Bian is technical make board ability and general silicate board comparative, thermal insulation board of poriferous structure heat preservation has sulfur aluminium acerbity salt stronger, smoother physics is characteristic, the heat preservation heat-insulating material that compares general mineral horniness conducts heat coefficient is lower, store hot index is taller, stronger extend a gender to wait. Apply in building project of heat preservation project, of systematic software integrated model can apparent promotion.
4, the Bao Hou side aperture is to conducting heat coefficient endangered?
1, fall in same density, hole wall is large, porosity is contractible, the diameter increases
(1) , gas (diathermancy can be small) occupy interior space to narrow as the plasmid carrier place of thermal convection current, the gas that measures deferent isolation to giving out heat in ministry of raw material in other words is little
(2) , hole wall is large, more interior space and character are held in ministry of raw material , calorific quantity very easy from Kong Bian the each other intermediate conveys.
Consequently the Bao Hou side aperture and conduct heat coefficient direct ratio.
5, whether porosity is bigger, is character of adiabatic heat preservation better?
(1) is aimed at the raw material with high density, Kong Bian packing sex porosity of strong, even if very big, diameter is small (polyurethane is epispastic aspect ratio relativity is inferior) raw material, but the scheduling that heat of solid state element moves to transmit each other barge against to attack inside hole wall is short, calorific volume is very light from convey among Kong Bian, conduct heat coefficient relativity is taller.
Be aimed at the raw material with low density, opening limit packing the gender is low, become when porosity is very big, conduct heat generally speaking coefficient is inferior, character of adiabatic heat preservation is good, but general compressive strength is a bit low, stick receive compressive strength difference.
Be aimed at the raw material with largish porosity in other words, otherwise abandons compressive strength, otherwise abandons character of adiabatic heat preservation.
(2) , when porosity it is dehisce model, gas is met with exterior begin heat exchanger, character of adiabatic heat preservation is reduced
6, is sulfur aluminium acerbity salt poriferous thermal insulation board of structural heat preservation and general silicate board what differs the place with likeness?
(Thermal insulation board of poriferous structure heat preservation is in the sulfur aluminium acerbity salt that 1) does not have classics metal finishing Sichuan province academy of sciences examines Jian fruit is 0.064, it is the aluminous silicate that shows level to save the academy of sciences to examine kind in little. Show level to sell the market to go up thermal insulation board of heat preservation of general aluminous silicate, commodity porosity big, Kong Xiao, density is low, pressing general principle is more acerbity than doing not have the sulfur aluminium of classics metal finishing salt thermal insulation board of poriferous structure heat preservation conducts heat coefficient is low, but in fact with atomic Konghe exceeding inside its Kong Bian blood capillary is more, and did not obtain reasonable enclosed, join form is submitted among Kong Bian more, aeriform negotiability is strong, conduct heat consequently coefficient relativity is taller.
(Thermal insulation board of heat preservation of acerbity salt of 2) sulfur aluminium because diametical relativity is very big, strong to wiping face mortar to attract Fu job faculty, stick with metope receive compressive strength tall.
(3) is producing craft, treatment craft, secret recipe to go up, people can be reasonable operate the Bao Hou side straight of eyelet of thermal insulation board of heat preservation of sulfur aluminium acerbity salt and aperture is sold with blending in the market, client and specific apply.
(4) shows level to divide metallic finishing technical outside, people held already enclosed of limit of opening of ministry of raw material technical, can make sure great majority is enclosed limit of raw material opening and even thoroughly enclosed, conduct heat coefficient will decrease further, compressive strength rises again, this technical in already using specific commodity.
(Thermal insulation board of poriferous structure heat preservation divides acerbity salt of 5) sulfur aluminium exterior and general silicate board similar outside, caused those who pledge to fly across already in character among them, from manufacturing technology, secret recipe different to general silicate board do not have some metallic finishing technical. Can say sulfur aluminium acerbity salt is poriferous thermal insulation board of structural heat preservation and thermal insulation board of heat preservation of general aluminous silicate are two kinds of big raw material.
7, is finishing of metal of thermal insulation board of heat preservation of sulfur aluminium acerbity salt technical dash forward where to show practical effect to be in?
1, conduct heat coefficient decreases substantially, the harm that reduces strength to suffer density and porosity is not great, the basis is technical of secret recipe different the level that reachs its to solve is different, can adjust heat preservation thermal insulation board conduct heat coefficient. Following it is the data information that in continous in relief city project pledges check center examines:
2, compressive strength of heat preservation thermal insulation board increases apparently
3, disappear is in besides conglutinate the soot of surface layer of heat preservation thermal insulation board, the metope air that when avoiding engineering construction, easy empty is stuck and creates is roused, the agglutinate that raised this kinds of raw material greatly is characteristic.
4, have extremely strong abhor water performance, external water portion cannot permeate ministry raw material, considered the regulation of project application property and moistureproof sex additionally, because heat preservation heat-insulating material is slack,prevent and reduce adiabatic heat preservation practical effect.
Say simple and easily, that is to say is not below the state that promotes Kong Bian Bao Hou, density, below the state that does not reduce character of heat preservation of raw material heat insolation that is to say, promote Kong Bian compressive strength from manufacturing technology secret recipe and raise a diameter, the agglutinate that raised raw material is characteristic, make software of system of all and adiabatic heat preservation can trust more.
8, how is software of system of heat preservation of body of wall of sulfur aluminium acerbity salt to handle metope sky of difficult problem of beat and fission?
1, first, sulfur aluminium acerbity salt is poriferous classics of all previous of limit of the diameter of thermal insulation board of structural heat preservation, opening is reasonable operate; is additional classics of all previous of board ability surface layer is solved distinctly, on one hand promotion of surface layer compressive strength, on the other hand dust is eliminated, to wiping face mortar to suck Fu ability of compressive strength job rises, prevent board ability then sticky metope sky goes out to rouse fission difficult problem when sticking.
2, sulfur aluminium acerbity salt is poriferous thermal insulation board of structural heat preservation is sticky stick after undertaking, maintain of course after 3-7 day, with metope be out of shape difference of distinction, compressive strength shrinks at least, making the photograph dissolve sex of metope and heat preservation thermal insulation board has been arrived at is, the whole process of gradual change color that retained metope and compressive strength of heat preservation heat-insulating material.
Wall body heat preservation
3, special model fight the distinctive antiseptic that is out of shape with compressive strength of heat preservation heat-insulating material the index basically agrees was added in cracking mortar, make compressive strength of whole system software, be out of shape the index is accomplished unified.
