*Assay: Weigh accurately about 1.0gm of Ammonium bi fluoride sample. Dissolve it in 100ml distilled water. Titrate with about 1N NaOH. Use Phenolphthalein as indicator. End point is Colourless to Pink.
% acidity as HF = A / B
1st calculate Consumption of NaOH, B.R. X Normality of NaOH X 0.02 X 100 = A
Then Divided the result with " Weight of the sample " = B
%NH4HF= %acidityasHFx57 / 20

Alkaline High foam ship hold cleaning detergent Cleaner is so important during Ship Hold Cleaning?
Alkaline High foam ship hold cleaning detergentis alkaline in nature which neutrilizes the acidic residue created due to the presence of moisture and products like coal, sulphur, salt etc. And emulsification effect of aquaatuff makes alll oil stain water soluble. It means Alkaline High foam ship hold cleaning detergent major role is to neutralize the acidic residue and emulsifying Oil residue. One more important feature of Aquaatuff high foam results in the formation of dense foam with high-pressure machines, which can easily be applied even on vertical surfaces.
Alkaline High foam ship hold cleaning detergent - Acts as an Acid Neutralizer - Useful for coal, Sulfur, Salt as its residue when in contact with water, is acidic in nature which directly damages the painted and metal surfaces.
Alkaline High foam ship hold cleaning detergent - Acts as an Oil residue Emulsifier - Useful for removal of coal and oily residue.
Alkaline High foam ship hold cleaning detergent - Results in Dense foam - Can be applied on the vertical surface for long duration.
Alkaline High foam ship hold cleaning detergentis absolutely free along with the purchase of slip coat - Hold block ( Pre load ) materials. Aquaatuff High foam Free 1000 Ltr with the purchase of 1000 ltrs Slip Coat Plus is available at Mumbai, Visakhapatnam, Ennore, Kolkata, Kandla - Gandhidham, Fujairah - Gulf

ALKAATUFF is also alkaline grade ship hold cleaning chemicals. Its major difference between simple alkaline cleaner and ALKAATUFF is foam and penetration power. ALKAATUFF contains high dense foam generation compound which helps to apply on a vertical surface for a LONG time ( 10 - 30 Minutes ) while Alkaline cleaner also have the property of foam but with large bubble which can't affect more than 30 seconds to 90 seconds. And ALKAATUFF contains ionic surfactant which helps to pentrate chemcials in residual cargo component. This is why ALKAATUFF is considered as the most effective Alkaline cleaner for ship hold cleaning. This is why marine chemical dealers tend to buy RXSOL ALKAATUFF more than any other alkaline detergent.

Good day,
Kindly advise the chemicals required and quantity for cleaning of cargo holds (Panamax) loaded coal to grain standard.
Reply :
1st segment to clean and neutralize coal rsidue :
Coal contain sulphur and many more others materials which is resulting corrosive effect on metal and painted surface. In chemical terms its proper cleaning means not only removal of its deposit to make surface clear and bright, But chemically neutralization effect also required. Our RX Tuff High foam ( Advanced formula of ALKAATUFF high foam ) having chemical neutralization formula as well as during cleaning process with high pressure machine resulting high dense foam to clean vertical surface of hold effectively.
2nd segment to prepare hold up to Grain standard :
After completion 1st step, if cargo hold can be rinse with diluted chlorine ( ppm level, 1 Ltr to 1000 Ltr Fresh water ) water followed by fresh water rinsing will result cargo hold for Grain loading standard.
3rd Required quantities :
For general cleaning each hold required 150 to 250 Ltr of RX Tuff High Foam ( New formula ) and 50 Ltr chlorine water ( Concentrated one up to 15% )
Note : Rusted and paint scale Area / part cleaning must required before using of any cleaner including 1st segment suggestion. For RUST REMOVING our product code is ( RXSOL-16-1088-025 ) and for Paint removing chemicals our code is RXSOL-18-1013-025
General cleaning tips :
Preparing Cargo Holds for loading Grain depends on the previous cargo.
1. Cargo Holds must be thoroughly cleaned and dry and trace of previous cargo in frames, beams, girders, and other structure.
2. There should not be any loose rust and or paint scale anywhere in the Cargo Holds, Bulkheads, upper and lower hopper spaces, underneath of Hatch Covers and tank top.
3. There should not be traces of live & dead insect & weevils.
4. Bilge covers should be cleaned of any cargo residues and have enough drain holes. Bilge cover needs to be grain tight but not watertight.
5. Bilge well should be cleaned of previous cargo dray and odour free.
6. Bilge suction should be operational at all the times.
Removal of cargo residue:
Air Blow from top using high pressure air to reach all accessible corners. Cargo to be swept, scrapped & collected in a drum. Attention to be given
• Australian ladder and its platforms and stanchions
• Beams and girders under cross decks
• Frames, beams, girders, and other structure
• Large pipes holding brackets behind the pipes
Then Cleaning and sweeping coal cargo from the hold as maximum possible by HELPER / Crew member
Loose Rust & Paint Scale:
A sharp hand scraper shall be used to take off the peeling rust & paint scale
Special attention to following areas:
• Australian ladder and its platforms, hand rails and stanchions
• Australian ladder and its platforms and stanchions
• Beams and girders under cross decks
• Frames, beams, girders, and other structure
• Large pipes holding brackets behind the pipes
• Hatch coamings and under hatch covers
• Booby hatches & cover
Tank top loose rust
Tank top should be free of loose rust and cargo residue
Any rust which can be scraped by hand scrapers should be removed.
The tank top should be rinsed with fresh water
Cleanliness of cargo hold bilges
Hold bilges must be cleaned thoroughly to remove all residue, rust particles and cargo stains etc.
The filter (Rose Box) must be cleaned thoroughly
The bilge well sections shall be washed with continuous running of sea water to remove all odour and later rinsed with fresh water
The principal behind cleaning of CARGO hold...
The 1st segment to clean and neutralize coal residue :
Coal contain sulphur and many more others materials which is resulting corrosive effect on metal and painted surface. In chemical terms its proper cleaning means not only removal of its deposit to make surface clear and bright, But chemically neutralization effect also required. Coal remover having chemical neutralization and cleaning formula, This product can be mixed with Alkaline safety liquid in open drums / Tanks as follows :::
1st of all take 100 Ltr COAL remover and mix with 80 Ltr water then add 20 Ltr alkaline safety liquid in drum. Spray this solution on entire surface area, And then use high pressure machine to achielve high dense foam to clean vertical surface of hold effectively. On heavily deposited spotted area This solution can apply directly to get emulsification of solid deposited mass easily.
2nd segment to prepare hold up to Grain standard :
After completion 1st step, dilute alkaline safety liquid again with water and sprayed diluted solution on cargo hold. Use high pressure machine water followed by fresh water rinsing will result cargo hold for Grain loading standard.
Note : Rusted and paint scale Area / part cleaning must required before using of any cleaner including 1st segment suggestion. For RUST REMOVING our product code is ( RXSOL-16-1088-025 ) and for Paint removing chemicals our code is RXSOL-18-1013-025

Know how to clean coal cargo hold and how to clean pet coke cargo hold from RXSOL chemicals. We are one of the largest Cargo hold cleaner for coal and pet coke manufacturers and suppliers in Mumbai, JNPT, Nhava Sheva, Sikka, Mundra, Gandhidham, Mundra, Kandla, Kolkata, Haldia, Howrah, Paradip, Diamond Harbour, Vishakhapatnam, Andhra Pradhesh, Tuticorin, Chennai, Tamil Nadu, India. We are also manufacturer cargo hold cleaning chemicals for coal and pet coke in Fujairah, UAE, Oman Muscat.
Two Major Benefit for cleaning of Pet Coke with alkaline cleaner:-
Pet coke residue contains oil content, which is creating more difficulties during cleaning operation. RXSOL ALKAATUFF high foam and one of our specialized product called Alkaline Safety Liquid which is absolutely non hazardous and biodegradable cleaner.
Petcokes also have sulphur content which is main cause of corrosion due to its electrochemical corrosion mechanism. In presence of moisture and sulfur metal surface charges as anodic and damaging the hold paint due to electrical ion charges. Here presence of Alkaline Safety Liquid / RXSOL ALKAATUFF increasing the alkaline effect and neutralizes the effect of Sulphur.
