Carbonate based fire extinguishing

Chemical Research Division

Process	A process for the production of carbonate based dry fire extinguishing agent
Area	Extinguish the BC type fire
Uses	This product is used for Extinguish the BC type fire
	Dry Chemicals (carbonate based) are one of the most widely used type of fire extinguisher that are effective mainly on Class B and C fires. This agent works by evolving carbon-dioxide and eliminates oxygen from fire and replacing it with carbon dioxide.
Scale of Development	This process is leased out by BCSIR authority
Major Raw Material	Mainly fine powder of sodium bicarbonate (NaHCO₃, baking soda)
Major Plant Equipment/Machinery	Grinding machine, mixing machine, S.S. still container
Details of specific application	Carbonate based dry fire extinguisher is most widely used to extinguish fires involving materials like oil, fats, solvents, gases, paint, varnish and live machinery
Status of Development	This process is accepted by the BCSIR authority and leased out
Ecological/Environmental Impact(if any, specify briefly	This process is environment friendly and after commercialization this product able to fulfill our national demand
Patenting details	Patented filed in future
Commercialization Status	This process is leased out by BCSIR authority
Techno-Economics	Available on demand
Cost of Production (Tk.)	70.0/kg
Key wards	Carbonate, fire, extinguisher, dry chemical

Chemical Research Division

Uses	Crude cottonseed oil has been used in toiletries (e.g. Soaps, facial wash, shampoo and lotions) industries.
Scale of Development	The product is standardized at Bench scale.
Major Raw Materials	Waste cotton seed.
Major Plant Equipment	Distillation equipment,Heating mantle etc.
Specific Application	The main fatty acids found in crude cotton seed oil are palmitic acid,stearic acid,linoleic acid,caprylic acid,elaidic acid. Palmitic acid does display antioxidant properties. Also Palmitic acid can be used as surface active agents Caprylic acid is used in perfumary. Stearic acid is mainly used in the production of detergents, soaps and cosmetics such as shampoos and shaving cream products
Status of Development	It is developed and tested.
Environmental impact	Process is environment friendly.
Commercialization Status	Ready for commercialization
Price (per Litre)	100/- (One hundred taka only)
Key words	Waste cotton seed,toilatries,distillation etc.
Inventor	Dr. Shahin Aziz

Fiber and Polymer Research Division

Uses:

It is used as a plant growth regulator in vegetables,fruittrees andtissue cultures to promote seed germination and toend thedomant state of lateral buds.
PGR aids in delaying the agingprocess of the plant, regulating the transport of nutrients, andpromoting fruitformation.

Major Raw materials:

Cytokinin, Indole-3-butyricacid, Gibberellicacid, Kinetinand others.

Fiber and Polymer Research Division

Uses:

Sustainable bituminous pavement construction suitable forBangladesh.

Major Raw materials:

General bitumen, Natural polymer, Polymeric antioxidants, Organicsolvents andothers.

Salient Features:

Renewable resource & huge amount of plastic & rubber wasteswill be used.
Import of 80-100 grade bitumen will be reduced by 5-8% & thusforeign currency will be saved.
Road strength will be twice stronger than normal roads & life-cost ofnormal roads will be reduced by 20-25%.
Large-scale industries will be established & thus employment willbe generated.
Clean & sustainable environment will be ensured.

Fiber and Polymer Research Division

Uses:	Asan Adhesive for Leather-based goods, especially for joiningparts of shoe soles and uppers, leather bags, moneybags, parses, leather jackets, etc.
Major Raw materials:	Adhesive grade Synthetic Rubber, Organic Solvents, Hardener, Antioxidants, tackifier, filler, plasticizer, curing agent, vulcanizing agent and sequestering agent.
Physical State	Highly Viscous Liquid.
Demand	20,000 MTs/Year.
Salient Features:	Very easy wayforpreparation of thesolvent based adhesive involving simplestirring and mixing process. It doesn’t requireany mastication process or equipment. Low-cost available solvents were used to make it cheaper. Antioxidant was used for making stable and long-lastingproduct. It is aproduct ofvery high adhesivebond strength.
