Development of Fly Ash and Light Weight Mineral Granules Based Thermal Insulated Ceramic Container Bases for Keeping Hot Pot & Hot Bowl

Thermal insulation based product development is the most important concern in the present age because we are using so many types of heating and cooking and baking devices and electronic equipment like microwave ovens, induction cook tops, Oven toaster Grillers, Electric tandoor, Roti makers, domestic furnace and electronic coffee & tea makers. When we take out our bowls and pots from the microwave ovens and such type of other kitchen devices then heat present in the walls of the containers like utensil, bowl & pot and heat present in the cooked food damages the top of the table and table covers. In order to prevent such things there is a burning need of development of thermal insulation bases and mats.


Introduction:
as we know that thermal energy is the most important form of energy for the food processing and cooking procedures but everything has its pros & cons similarly heat energy also has its pros & cons as it is beneficial in terms of cooking of food items but harmful in its burning and damaging effects on the contacting and touching surface and substrates.Some of the materials found in nature are very good thermal and electrical insulators like rocks, wool, some minerals like vermiculite and closed cell enclosed perlite.By using such type of raw materials in the composition mixture of ceramic products in a fixed and appropriate proportion we can develop thermal insulator ceramic products.
Light weight earthen mineral effect: our planet earth is the only planet which has so many minerals in its mantle and crust areas , some minerals are heavy weight and are of high density type and rest some of other minerals are light weight minerals like dolomite, muscovite, perlite, feldspar, calcite and quartz these minerals have lower gravity values in comparison to standard gravity (2.85).The effect of using closed cell expanded perlite upon its usage in the ceramic composite mixture is to reduce the over all weight of the ready ceramic product and other benefits of using it are to lower down the thermal conductivity values of thermal insulated ceramic product and increase in compressive strength of the concrete mixture.

Basalt fibres usage effect:-The type of fibres which are made from basaltic rocks are known as basalt fibres and naturally occurring basalt fibres are obtained from silica/ alumina oxides.They are the best replacement of asbestos fibres which is harmful for our health and caused respiratory disorders.There are many advantages of using basalt fibres in the concrete and ceramic composition mixture because basalt fibres are having strong tensile strength, high density and high elastic modulus.Its usage helps in increase in corrosion resistance and chemical stability in nature of composite even in alkaline mediums.

Fine sand:-very fine sand helps in increasing the porosity of the composite and on the other hand it also increases the gripping power of the ceramic binder ie;-cements as it increases compressive strength of the material so it helps in the increase of durability of the ready ceramic products.It also helps in enhancement of resistance of penetration in side the ceramic composite so it helps in the increase in thermal resistance.Grey cement ( J.K cement) 71 gm 2.
Compressive strength 8.7 MPa 21 MPa Results and Discussion:-Thermal insulated ceramic Bases of model-1 which were composed of grey pozzolona cement (JK cement) are made up of pozzolona grey cement whose compressive strength is less and thermal conductivity is more -1.46W.m -1 k -1 whereas model-2 TISB's were more efficient in many properties as compared to model -1 specially in their high thermal expansion coefficient values and high thermal resistance.

ABSTRACT
The solution for such type of serious problem exists in the invention of such composite insulator materials for making curtains/ curtain pads and window insulator covers to avoid the entry of cold breeze and fog.

Introduction:-
The problem of extreme cold is not the present time problem instead it's a issue of thousands of years back in the past everywhere.some times extreme cold breeze flows in some states or specific geographic area along with appearance of too much fog and mist in the morning time such type of climatic conditions adversely affect the human health, Aquatic life,wild life etc.when we are talking about its adverse effect on the human health then we can say that by the cooling of body parts leads to frostnip,frostbite (freezing injuries), immersion foot and hypothermia (non freezing injuries).Among non freezing injuries hypothermia is most serious one.The arrival of cold wave in the Madhya Pradesh and some other states which results into drop of 4-5 ⁰C in various districts like Bhopal,Ujjain,Indore, Seoni,Chhatarpur,Sagar,Datia and Gwalior (weather report obtained from India Meteorological Department's Bhopal office.) in the last month of December 2021.Due to Cold wave the normal room temperature decreases very rapidly and it was reported 4⁰C in Datia and Gwalior.The problem of extreme cold originates from arrival of cold breeze from north east of our country which is also called as cold wave.
In order to prevent from the adverse effect of extreme cold we can use and install some insulator curtain pads and window insulation covers our windows and ventilation.Jute,cotton and wool are very good insulators of heat among organic category where as polystyrene foam,polystyrene and Khaadi cloths are having very good thermal insulation properties as a man made products.Window insulator cover:-by tie up with ropes to grills.Experimentation :-After the successful installation of these insulator composite models in the windows I have taken readings of temperature outside and inside the rooms of house.Verification of the effectiveness of insulator composite models was very necessary for the analysis and monitoring part.I have monitored my composites for the period of 30 -30 days for each insulator composite model.For taking the reading I have kept a gap of 3 days in case of insulator curtain and 2 days in the beginning and later on 3 days gap between two subsequent readings.For the reading I have used IR thermometer to take the temperature recordings of outside the window and inside the window ( room).Data Analysis:-Insulator curtains or cold insulator curtain pads obstructs the cold efficiently by its layering effect of adjacent insulator materials and Vertical band effect of hard board bands which helps in discontinuity of flow of air uniformly on the surface of composite.This composite if we apply on all the windows and ventilation of room then it prevents the room temperature from fall down and approximately it maintains temperature higher than outside 3-4 ⁰C.Data Analysis:-Window insulator covers obstructs the cold efficiently by its layering effect of adjacent insulator materials and Air insulation effect of hard board based used egg trays which helps in filling of air uniformly in its exposed surface on outside the room.This composite if we apply on all the windows and ventilation of room in winter season then it prevents the room temperature from its falling and approximately it maintains temperature higher than outside in the range of 3.3 to 5.4 ⁰C.

Date of recording
Results and Discussion:-Insulator composite designing is vast field of development of thermal composite insulator materials and models in the field of green chemistry and Energy savings of buildings.In the result part I found that the energy saving efficiency or temperature maintenance capacity of window insulator covers is better than insulator curtains.As windows covers maintains temperature higher than outside upto higher limit of 5.4 ⁰C.
