CORROSION RESISTING CEMENTS

FURA BOND

FURA BOND-ACP:- FOR APPLICATION WITH ACID PROOF BRICKS
FURA BOND-C :- FOR APPLICATION WITH CARBON BRICKS AND TILES

DEFINITION

FURA BOND is a self – hardening cement consisting of an inert powder which is mixed with a furane synthetic resin syrup to produce a mortar used for bonding acid – resisting bricks and tiles for acid-proof constructional work.

It is specially designed to afford resistance not only to acid condition (usually provided by the use of silicate cements), but in addition, to resist alkaline conditions or mixed acid and alkaline conditions.

FURA BOND is resistant to wide range of acids, alkaline, solvents and oils, to water penetration and erosion from flowing or turbulent liquids within its chemical resisting range. It is not resistant however, to nitric acid, which attacks it even in dilute concentration, nor to other oxidizing acids. The good  resistance to caustic, alkalies and solvents is obtained without heat treatment.

A special grade is available having all the properties of the normal FURA BOND-C grade, referred to above, but which, in addition is resistant to hydrofluoric acid.

FIELD OF APPLICATION

FURA BOND cement is used for bonding or pointing of bricks and tiles for the construction of chemical resisting tank linings, floor surfaces and joining of channel for conveyance of corrosive chemicals, within the limits of its chemical resistance, range and temperature.

INSTRUCTIONS FOR USE

FURA BOND cement is supplied in two separate parts, FURA BOND Powder and FURA BOND Syrup. It must be mixed in the proportions given in the above data table, strictly in accordance with the following Instruction and no other material added.

Mixing Operation – mixing should be carried out very thoroughly and carefully in a clean enameled dish or bowl. Any lumps in the powder must be broken down careful mixing. Mixing is best carried out by adding powder to syrup. Only mix small quantities at a time. Arrange mixing so that mixed mortar is used up quickly and does not remain in bulk  for longer than 20 minutes. At temperatures 70F, or above, kept the mixing pan and contents cool by immersion in water.

Working time – Under normal atmosphere condition FURA BOND mixed mortar can be used up to 20 minutes from mixing. It is however, pointed out that in the setting of FURA BOND mortar some heat is generated, and if bulk masses of FURA BOND mortar are allowed to remain under fairly warm conditions, considerable heat can be generated and lead to a flash set. When the conditions are hot and humid during mixing operation , it is advisable to keep the cement mix in a cold water basin so that temperature is kept around 25 deg. C .

To avoid this, it is essential that the mixed mortar is spread in a thin layer on a flat tray. This is important because left in a mass as such, the mortar may generate heat on exhothermic reaction, particularly when the room temperatures are above 80F.

Hardening time – this is depending on atmospheric temperature; under normal conditions and mixed mortar is fairly hard in one day, with colder conditions in two days period. It is recommended that the mortar is left for eight days before placing under service conditions. While warmth will, of course, accelerate the hardening, it is not normally necessary to heat – treat to obtain chemical resistance to acids, alkalies and solvents. The color of the set, hardened mortar is blackish – grey.

Application for laying tiles and paviors completely in FURA BOND Mortar – FURA BOND Mortar may only be applied direct to bitumen (especially sanded bitumen), rubber and synthetic resin surfaces and unglazed stoneware, bricks etc. Concrete cement screed and metal surfaces must first of all receive an isolating  layer of bituminious material by applying a good coat of our lacquer to the carefully  cleaned and dried surface.

In all cases the surfaces to which FURA BOND mortar is to be applied must be clean, dry and free from rust. During setting and hardening no water, steam or acid must come into contact with the FURA BOND mortar.

When tiles or bricks are laid completely in FURA BOND mortar narrow joints should be used, 3mm width is adequate.

Storage – FURA BOND powder and syrup should be stored under cool and dry conditions.

SPECIAL REMARKS

When working in closed tanks FURA BOND, ensure adequate ventilation.

GRAPHITE FILED CEME
NTS – REPAIRING OF IMPERVIOUS GRAPHITE EQUIPMENTS.
NO.K-14 CEMENT.

                                  USE : FOR REPAIRS AND JOINTING OF IMPERVIOUS GRAPHITE.

These cements are versatile in repairing impervious Graphite equipment such as graphite exchangers, Dilution coolers, graphite pump parts build – up, and cements for plugging in services.

The cement manufactured is a two-pack system which comes as powder and liquid. These are normally mixed in the ratio of 1:1 in a plastic plate with a small plastic  spatula slowly but intimately without generating heat in the system. After a through trowable mix is formed the cement is applied on to the dry clean parts that is to be repaired, with a knife. The parts that are joined should be cleaned with an emery paper and blown with compresses air. Care should be taken not to exceed thickness of cement more than 1/8” in any case. These repaired joints are to be kept under slight pressure infra red ray lamp should be used on the joint for faster curing and higher strength.

Shelf life of both liquid and powder is around 4 months if maintained in a cold room of 150C. Pot life of the cement mix is around 30 minutes. If however atmosphere temperature is higher then mixing can be done in a cold room and jointing done at the spot.

PROPERTIES OF CURED CEMENT:

1. Density                                             : 80 Pounds per cu. Ft.
2. Tensile strength                             : 1500 Pounds per sq. inch

S – 140 COATING COMPOUND

USE: FOR COATING OF POROUS GRAPHITE PARTS TO MAKE IT
IMPERVIOUS AFTER EQUIPMENT REPAIR

 

S – 140 Coating compound is a brownish black viscous resin supplied with an accelerator for mixing and coating application normally whenever any impervious graphite equipment becomes permeable in service. This coating application makes graphite parts once  again non-porous on the outer surface increasing life material.

PREPARATION OF THE COMPOUND

Around 250 gms of the coating compound covers four to five square mtr of required surface. The job has to be planned as per work area and not more than 250 gms, mixed at one time. Resin about 250 gms is poured into one plastic bowl and 8-12% weight of catalyst dropped slowly drop by drop while mixing with a knife. Occasionally small quantity of acetone may be mixed to decrease its viscosity if required. Now the mix ready for painting. Any ordinary paint brush is sufficient for painting area should be free of dust, moisture or any contaminants.

APPLICATION OF COATING COMPOUND

Pot life of the formed is normally 20 mins at 250C. the paint should be worked into the pores with brush smoothly, and within one to two hours a hard crust is formed with the paint set. Two such coats should be applied minimum before finally curing it with dry air. The finally cured cement becomes very hard and scratch free with any sharp instrument with hand. Any uncured cement can be removed before setting with acetone or carbon tetrachloride.

STORAGE OF COMPOUND

The cement compound should be stored at 150C so that it has a life of 4 months. Any moisture on the surface of the liquid should be decanted before use.

NOTE:

The subject cements are irritants to skin and therefore to be handled with rubber or latex gloves. Remove uncured cement with carbon tetrachloride or acetone from hands.
