WHAT IS SMC?

A release agent, a diluent, a hardener, a polymerization inhibitor, and a thermoplastic in an unsaturated polyester resin that is a thermosetting resin a pigment and a thickener are added while maintaining a certain degree of viscosity by mixing a water storage agent and a dispersant.This compound is aged to the target viscosity with SHEET made by forcibly impregnating glass fibers 1 inch apart It refers to a method made by creating a semi-solid state and compressing and molding it into a large hydraulic press at high temperature and high pressure.Current scope of application includes water tanks, bathtubs, waterproof plates, automobile parts, doors, manholes, exhaust ports, and electrical insulation cases It is used in various fields of industrial building materials.

Installation and caution

Customers are requested to make foundation pad construction according to the designed specifications and the strength of the site.
Check the evenness of foundation (within 5mm) and the flatness of base material. (within 0.5mm)
Check rust of the external reinforced material and any bolts and nuts, their tightness.
check installed state of the external ladders and water level gauge.
check bending of the water tank wall panel(maximum up to 1% of water tank height) and check skewness of the water tank.
Check a corrosion inhibitor coating on the internal reinforced material and bolts tightness.

※ The above mentioned data are subject to change depending on the testing conditions and environment.

Design Criteria
- Earthquake Resistance
- Designed to KH = 1/3G
- Wind Pressure
- Designed to withstand wind at a 60m/sec speed maximum, even when the tank is not filled with water.
- Snow Load
- Designed to withstand 60kg/m² of snow load.
- Hydrostatic Pressure
- Designed to restrain distortion from hydrostatic pressure. Maximum distortion rate of wall panels after 48 hours of full tank is less than 1.0% of the total height of the water tank.
- Strength of Drainage
- Designed to withstand 100kg of water poured to the tank with no leakage, with 100mm-diameter flange installed on the internal side of the wall of a full tank and props on the bottom part of the pipes every 70cm.

PERFORMANCE
AND FEATURES
OF INSULATED
PANELS

Outstanding Insulation
GRP insulated panels are made from applying polyurethane, an efficient insulator on a single-layer panel, and covering it with a special synthetic resin foamer, creating a sandwich-like structure panel with high insulation performance.

Performance
GRP water tanks have outstanding insulation and dew-proof as triple sandwich structure. Because single panel with heat retention which has 250 times conductivity more than other metal (STEEL, SUS etc) is laid, and polyyurethanes foam with excellent insulation effect is inserted as lagging. Lastly special cover made of synthetic resin vacuum-molded is put on.

Reinforcement System
of CK GRP Water Tank

Internal Reinforcement System

※ The design criteria of water tanks are safeness, hygiene, and convenience.

Outstanding strength, durability, water tightness, and appearance. Safe structural design.SMC water tank strengths are gained by connecting the panels with stainless steel tie rods from the inside of the tank.
※ Stainless steel 316 internal ladder is optional

External Reinforcement System

※ Outstanding durability and hygiene. Easy maintenance and repair.

Glass fiber reinforced panel is mulded under condition of high temperature and pressure to maintain the best endurance.Since using stainless steel for inside structure, plated steel for outside and HDG for outside, it shows best performance against corrosion.

PARTITION TYPE
WATER TANK

One water tank in a limited space creates an effect of installing multiple tanks, which is an economical alternative and efficient for maintenance.

Performance
- Maximized volume in a limited space
- The Partition Water Tank can maximize the tank volume than installing separate water tanks, especially for limited spaces, such as basement or small areas.
- Precautions when cleaning
- One of tank must maintain less than 50% of water level for safety reasons when cleaning the other tank.
- Easy Maintenance
- Two tanks are installed as one, which enables easy maintenance and does not require water supply cutoff for cleaning.
- Economical
- The Partition Water Tank is more cost effective, including the cost for labor work, compared to installing separated tanks for different purpose.
- Various Usage
- When a partition is applied, one tank can be utilized as a potable water tank, and the oter for utility water(for fire hydrant).

Installation Example
If tanks for two different use are needed in a limited space of area or a boiler room, a 16-ton partition type tank can be installed to use half for potable water 8ton and the other half 8ton for ytility water. 8ton however, if two separate tanks are installed instead, it needs 1 meter distance between the two tank. So each tank capacity is only 6 ton.
Section installation
1.5m × 2m × 2m = 6ton

2m × ( 2m + 2m ) × 2m = 16ton

CONCRETE PAD PRODUCTION STANDARD

PAD Production Standard
- Width : over 300 ~ 400mm
- Height : over 600mm ( including base frame )
- Gap : Max, 1m or less Outer
- dimensions : W, L+400mm
- Horizontal degree : 1/500 or less(Keep the top surface as flat)
ex) 3W × 4L × 2H

※ SMC water tanks are recommended to be installed indoors for freeze prevention and maintenance.

Installation Space
For installation and maintenance of water tanks, the tanks require an extra space of at least 600mm on each side and 1,000mm to the ceiling.
