PAINTING of SOLAR POWER PLANTS Structural Galvanized Steel Fabrications
Structural MILD STEEL Fabrications
: Recommended Process :
Greetings from Prof PRADEEP VAIDYA : CEO : PROMTECH GROUP. Innovative Coating Industries, MIDC Pimpri; PUNE, our manufacturing unit offers the following Products for De-Greasing, De-Rusting Chemicals used by Dipping / Brushing Process at Room Temp. The time for total cleaning is accomplished within 20 to 60 minutes.
PRECLEANING / SURFACE PREPERATION BEFORE PAINTING : It is most essential to completely clean all the Oil, loose Rust, Dust, dirt grease & foreign matters form inside, outside of the Steel Tubes, Angles, Channels , Metal and Fabrications. POST PAINTING ANTI CORROSION DEPENDS GROSSLY UPON THE TOTAL AND COMPLETE PRE-CLEANING.
MOST IMPROTANT FACTs on use HYDROCHORIC ACID Based De-Rusting: Never use HYDROCHLORIC ACID for MS or GI Tubes Pickling. Though very fast in cleaning, the acid will surely leave Residual Acid ions, in the Micro-pores and crevices of the metal surface. This phenomenon is called as HYDROGEN EMBRITTLEMENT. This causeS POST CLEANING CORROSION ( Sub-Surface Corrosion ) on the metal. RUSTING WILL TAKE PLACE with DOUBLE THE SPEED . Re-Rusting can happen from one day to 60 days. Rusting will take place BELOW PAINT/ Coating Film ( Creeping Corrosion ) The chloride fumes are continuously generated from HCl and these fumes pose a great HEALTH HAZARD to the operators, will corrode the Steel structures, Building Trusses, Metal Buildings, Chimney , Steel stored in the nearly vicinity of this Metal Cleaning / Pickling area. These fumes spread Hydrogen Chloride ions in the atmosphere and are very dangerous to mucous membrane and lungs and will prove as a very serious health hazard. These fumes will be extremely detrimental to the overall functioning of the Equipments. Salvage costs will prove to be phenomenal in this case.
PROCESS for CARBON STEEL / MILD STEEL & GALVANIZED Steel Structural Fabrications:
( 1 ) RUSTOGEL 1406 : RUST CLEANING & REMOVAL Process by BRUSHING APPLICATION : The VERTICAL & Standing Galvanized Steel Structures, Support Structures, get rusted due to OXIDATION in Humid, Damp Moisture in the Atmosphere. This Rust MUST BE REMOVED before applying any kind of Paint. RUSTOGEL is a Phosphoric Acid based DERUSTING GEL (Viscous Brushable Liquid). It is applied by Brushing all over the Rested MS / GI Fabrication. It is allowed to react with the rust for 10 to15 Min. This Loosens the rust. This treated surface is Water Washed neatly and IMMEDIATLE Dried by using Compressed Air Blow. The structure MUST BE PAINTED WITHIN 8 Hours. RUSTOGEL is a water based Acidic Cleaner, is RoHS Compliant Safe for Workmen. RUSTOGEL is offered at Rs 70 Per Kg in 35 Kg HDPE Carbuos Packing+Vat Ex Pune works.
IMPORTANT : Derusting Process by using OIL BASED Chemicals ( viz: WD 40 or similar ) are VERY SLOW in Rust Removal ( There is NO CHEMICAL ETCHING for Rust Removal & may need 4 hrs to 24 Hrs for moderate rust removal ). Oil based Chemical Cleaners are basically RUST PREVENTIVES, Apart from slow action, these cleaners also Leave a OIL BARRIER Coating on the treated Surface. Due to Oil film, this will totally MAR ADHESION for any PAINT/COATING ( Zinc Rich Paint coating in this Case ). Hence Oil Based Cleaners are NOT RECOMMENDED for such Applications which involve Painting process, post De-Rusting.
( 2 ) POST CLEANING RUST PREVENTIVES Application : Work In Progress Corrosion Protection For all such structures which are Not to be Painted and are required JUST TO BE STORED in the Yard : All Carbon Steel Fabrications , & Raw Steel, which have WIP Period of upto 3 months shall be coated with a very light layer of Oil-Based Rust Preventive. We offer AQUANIL DWO : Dewatering Oil cum Wet Film type Rust Preventive. This is available for Rs 145 per Litre +++ Ex our Works in 35 Ltrs HDPE Carbuoys.
( 3) ZINC RICH PAINTS / ZINC METAL SPRAYS
These products offer a uniform ZINC METAL POWDER Coating on all MS and Galvanized metal . When used as recommended, ZINC RICH PAINTS offer 15 to 20 years of Total Corrosion Free surface. We offer FOUR PRODUCTS in this range. ZINKOTE 20 GP & PREMIUM Grades are offered in 20 Litres Packing ( Rs 390 & Rs 630 Resp.) Zinc Metal Spray ( Light Grey Finish ) 500 ml Aerosol is Offered for Rs 275 / Can and Zinc Bright Spray ( Silver Bright Finish ) 500 ml Aerosol is Offered for Rs 320 / Can Ex Pune & Thane.
Products offered for DERUSTING / Pre-Cleaning
BULK QUANTITY OFFER : We offer Discounted Price to our Bulk Qty Buyers. Offered Discounted Prices based on One time Purchase Quantity, ( 100 Aerosol Spray Cans or 100 Litres of ZINKOTE Paints.)
SALIENT Features, Quality Standards & USP These Paints / Sprays confirm to the requirements of most Indian, British and ASTM Specifications. These Paints offer 20 to 25 Microns Film, 88 to 92 % Zinc
in the DFT, Zinc Purity of 99% +. Pass 500 Hrs Salt Spray (15 yrs + in the Normal weather conditions ) Pass Cross Cut Hatch Test for Adhesion as per IS Specs. Complete details on all these Tech properties are available in our Literatures / Website.
Approvals & Recommendations Our Zinc Rich Paints are Approved, Used and Recommended to their vendors Fabricators by RIL, REIL, NPCIL, L& T, BARC IIT, EIL, S&P, DOKA, Thermax, TATA, St Gobein, SIGMA BGR Energy, ZENTIH, INDUS Towers 25+ EPC / INFRA Firms & by NABL Accredited Test Lab from Mumbai
Safety Pre-Cautions : During entire Pickling ,Cleaning & Painting Process, every operator / Worker MUST use all the Safety gear, Goggles , Rubber Aprons, Gum Boots, Hand-gloves etc. In case of Spillage / Splashing of any of the treatment chemicals, flush the affected area with plenty of running water for 2-5 minutes.
Effluent Treatment : All wash Waters, Floor Swipping, Splashings of Chemicals must be neutralized by adding LIME WATER, ALKALINE Water, Alkaline Waste. Final pH of out-going water must be maintained between 7 to 8.5.
All our offered products are RoHS compliant, extremely safe for workmen & confirm to requirements of IS , ASTM & BS Specs. In case you need any additional Information, please feel free to call / Email me. Thanks & Warm regards:
