The constructional method of the preservative coat of Carbon-sand filter of the present invention is as follows:
(1) preparation of construction
1. main raw and requirement
Main raw: the special enamel of food grade epoxy resin, food grade, solidifying agent, thinner, woven fiber glass, cotton (steamed buns stuffed with sweetened bean paste cloth)
B. material requirements
Raw material must select product certificate, and before construction, inspect qualified material by random samples.
Food grade epoxy resin: faint yellow to brown color clear viscous liquid; Softening temperature 12-20 DEG C.
Epoxy curing agent: light brown in appearance transparent liquid, proportion 1.08-1.09/25 DEG C, viscosity 1.1-1.3pas.
Food grade epoxide diluent: pure grain alcohol, water ratio is less than 1%.
Glasscloth: middle alkali Non-twisting glass fibre cloth, quality product meets GB/T 18370-2001 standard; Without the need to dewaxing.
Quartz powder materials: water ratio should not be greater than 0.5%, fineness requirement 0.16mm aperture sieve tails over and should not be greater than 5%, and 0.09 aperture sieve tails over and is not more than 25-30%.Quartz sand enters before scene should drying be complete, and guarantee up to standard after can enter working-yard.
2. concrete surface process
A. basal plane requires firm, closely knit, smooth, can not flake, the defective phenomenon such as crackle.
B. splay angle or small round corner should be smeared in inner corner, pond and turning, and basic unit must be dry, should not be greater than 6% dark for water ratio in 20mm thickness.Surface dust on basal plane, greasy dirt etc. should be cleaned out, and alcohol product should be used to clean, have a negative impact to avoid its residue to glass reinforced plastic during greasy dirt cleaning.
C. concrete surface humidity process
As moister in structure basal plane, disadvantageous effect will be caused to the construction quality of Corrosion Protection of Fiber Reinforced Plastics.Therefore the process to basal plane moisture issues must be paid attention to, to ensure that construction quality reaches requirement.
Be equipped with enough ventilations, heat, dehumidification equipment.
Shutoff can flow into the water source in filter tank.And heated baking in the moist position of filter tank inwall; Warming-up device employing electric space heating appliance or electrothermal tube heating, forbid to use tungsten-iodine lamp and electric furnace.
Because roasting plant power consumption is comparatively large, require that full-time electrician is ready, use cable and lock case that current load is larger.
For accelerating the time of drying of concrete surface, adopting and ventilate and dry the drying mode combined; Within 6 hours, ventilate, within 6 hours, dry.
According to on-site actual situations, dry air, humidity hour by day, increases ventilation time; When night, atmospheric moisture was large, increase drying time.
After the degree of drying of concrete surface reaches construction requirement, apply for checking and examination in time and brushing primer, prevent from getting damp.Corrosion Protection of Fiber Reinforced Plastics construction can be carried out in surface after brushing primer.
3. operating environment:
Operating environment: basal plane is smooth, construction environment temperature is 10-25 DEG C and is advisable, and relative humidity should not be greater than 80%, will add dehumidifier when humidity is excessive, when temperature is too low, should adopt temperature-boosting measure.
4. Seeding location: pond body inwall absolute altitude 47.50m-48.50m, H=1000 ㎜.
(2) technical process
1. brushing primer, paving woven fiber glass
Brushing the first layer primer
Base cleaning and dry after, start brushing epoxy primers.Epoxy resin and diluent ratio are 45%:55%, make epoxy
Resin can infiltrate through the inner 5-10mm of cement, and frp layer is firmly combined with concrete surface.
During construction, the epoxy resin prepared is poured in container, with cylinder roller coating one time on the filter tank internal-wall concrete basal plane handled well at leisure, and allow it solidify.Primer solidifies tack-free with surface and uses cotton ball soaked in alcohol wiping, and cotton balls does not change color as completion of cure.
B. basal plane pit is then scraped resin-bonded mastic and is entered to fill up
After primer solidification, as basal plane still has pit, then scrape resin-bonded mastic and fill up, scrape resin-bonded mastic mode and be divided into and completely scrape and point is scraped; Concrete construction method is determined according to field condition, if substrate surface overall condition is poor, completely should scrape resin-bonded mastic, adopts point to scrape resin-bonded mastic under normal circumstances.
C. brushing second layer back cover glue, paving woven fiber glass
After resin-bonded mastic solidification, brushing second layer primer; Then paving woven fiber glass (height H=1.0m).
Adopt leaching cloth method paving woven fiber glass, woven fiber glass gel content can be made so even, and gel content easily rests in 60%.
The epoxy resin prepared is painted on woven fiber glass, strikes off at leisure with trowel, and allow it solidify (set time is 24h).
During paving, woven fiber glass is along Flow of Goods and Materials direction, and cloth stubble overlap joint is not less than 5cm, and levels cloth seam staggers and is no less than 5cm, and cloth stubble is straight, surfacing.And should guarantee that resin sizing material is immersed in glass fibre, ensure that every one deck woven fiber glass is sturdy, do not produce the defects such as bubble.
2. polishing after solidification
Brushing primer, paving woven fiber glass complete, solidify after, carry out overall grinding process to the basal plane after solidification, number of processes is no less than five times, and the surface after process must be smooth, clean, smooth, without any defects such as pinprick, woven design, bubble, burrs.
3. middle level glue, paving cotton (steamed buns stuffed with sweetened bean paste cloth) is brushed
Roller coating on the basal plane of the cylinder used for epoxy resin that oneself prepares at leisure after polishing one time; Then paving cotton (steamed buns stuffed with sweetened bean paste cloth, height H=1.0m); Finally the epoxy resin prepared is painted on cotton, strikes off at leisure with trowel, and allow it solidify (set time is 24h); With surface tack-free and with cotton ball soaked in alcohol wipe examination, cotton balls does not change color as completion of cure,
4. secondary polishing
Brushing middle level glue, paving cotton complete, solidify after, again carry out entirety at the basal plane of solidification and polish, guarantee surfacing.
5. face is coated with
The food grade epoxy resin configured together with solidifying agent, promotor Homogeneous phase mixing, pour in container; Make Corrosion Protection of Fiber Reinforced Plastics layer thickness reach design requirements with cylinder roller coating at least 2 times, and allow its solidification (set time is 24h).
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
