Description

Heat insulation 1000 ℃ of thermal-insulating waterproof spary paste coatings

Heat insulation 1000 ℃ of thermal-insulating waterproof spary paste coatings are thickness fiber pasty state lotions, have solved the heat-insulation and heat-preservation a great problem of the industry high temperature such as petrochemical complex, metallurgy, electric power and the special-shaped equipment that is corrosive.Construction need not stop production, and does not need looping and reinforces subsidiary material.Greatly reduce engineering cost and maintenance cost.Be high-quality light energy-saving type novel silicate product, its unit dry weight kg/M ³＜500, thermal conductivity W/mk＜0.12.

Its technical recipe is as follows:

One, silicon sol is made: 15 °-35 ° of ring temperature

1,1: 14 water (about PH=7) of edible salt (sodium-chlor) preparation salts solution (as 20 ℃ of proportion 1.05-1.06) 70kg

2, neutral water glass (water glass) 10.5-11kg

3, technical hydrochloric acid 2.5-3kg

4, tap water (about PH=7) 25-40kg

Slowly pour into water glass in the salts solution, stirred fully about 5-10 minute, after pour technical hydrochloric acid into salt solution, stir in the water glass solution, at this moment will separate out silicon sol (PH6.5-7.5) in a large number in the solution, (used water glass, hydrochloric acid were regulated when silicon sol PH deviation was big before not having the water flushing to water down silicon solution with flushing with clean water after 15-30 minute.）

Make clear water proportion＜1.05 of its flushing.

Two, the long-pending technology of Magnesium Silicate q-agent (sepiolite) enlarged surface:

1, the pure pure Magnesium Silicate q-agent 90-100kg(white of quality is for well)

2, put into 0.5M ³In the anti-sour container

3, pour 250-300kg clear water (about PH=7 15 °-50 ℃) into

4, stirred 10-15 minute, make water, sepiolite fully fused

5, slowly inject technical hydrochloric acid 75-85kg(and note the anti-expansion protection of acid)

6, stirring makes sepiolite hydrochloric acid fully react (PH=5-6)

7, leave standstill 3-6 hour (not reaction during stirring)

Can reach up to a hundred square metres through the every gram sepiolite of above-mentioned art breading surface-area.

Three, potassium aluminium sulfate (technical grade alum) becomes the powder face with pulverizing mill powder essence.

Four, aluminosilicate fiber cotton 80-85kg pours 1.5M into ³(PH=7,15 °-35 ℃) clear water 1-1.3 ton in the clean water basin, thorough washing stir pulls aluminum wool out seepage flow water outlet with screen cloth at the bottom of the sand-like glass grain that makes in the aluminum wool sinks to the pond from water, make about its gross weight (Dai Shui) 500kg.

Five, technical grade formaldehyde (water) 9-11kg

Six, pearlstone (granularity 2.5mm tails over＜5,0.15mm throughput＜8 for tap density＜80, water ratio＜2), what and globule size of 6-7.5kg(ginseng people amount are concerning unit weight, intensive parameter)

Seven, hollow aluminosilicate microballon (from fly ash in electric power plant, sub-electing)

Eight, aluminium hydroxide (technical grade)

Nine, zinc oxide (technical grade)

Ten, pigment (preferably need not contain lead pigments)

11,1: 10 aqueous solution of organosilane solution (product is changed in Beijing two)

Work in-process are synthetic:

1, will pour in the retort through the sepiolite 415-485kg of enlarged surface art breading.

2, the water-free silicon sol 55-65kg retort of falling people stirring is heated 50-60 ℃

3, pour potassium aluminium sulfate powder 6-7.5kg into retort

4, tap water being injected retort 110-130kg fully stirs and heats 90 ℃

5, industrial formol water 9-11kg slowly being injected the retort temperature kept 15-25 minute for 92-97 ℃.Fully stir, make fully reaction such as siloxanes in the sepiolite, silanol and formaldehyde.

Above-mentioned five reactions also can be greater than 0.40M ³React at twice by 1/2 amount in the big iron pan.

Total synthetic:

To synthesize sepiolite formaldehyde ointment and from retort, pour 1.3M into ³In the agitator (pond), the agitator that is driven by power-equipments such as motors constantly stirs, constantly water is cleaned up the about 500kg aluminum fiber of permeate cotton small quantities of and puts into agitated pool in small batches, wait after whole inputs restir 30-60 minute and make aluminum wool fully and ointment be combined into thickness fiber pasty state lotion outward appearance and be canescence PH6-7.5.

With manual or the slow speed of revolution it is combined evenly with heat-insulation and heat-preservation cream pearlstone 6-7.5kg.(when spraying the time can change globule size as one sees fit) this product stands in order to make it that high temperature can substitute perlite with the pure aluminium silicate cenosphere more than 1000 ℃.Can infiltrate aluminium hydroxide, each 10kg of zinc oxide also can infiltrate the appearance color that other pigment change its ointment.Available 1: 10 water after this soft paste drying when construction, organic silicon solution brush or spray coating heat preservation surface will make for 2-3 time its lagging material have the hydrophobic drip-preventing function.
