Explain polymerisation vinyl chloride and its applications.
PVC and its applications - It is acquired from polymerisation of vinyl chloride in the presence of a catalyst as peroxides at about 500C. The properties are as mechanical strength, flexibility, porosity, electrical and moisture absorption properties can be changed through adding certain materials. PVC has fine mechanical and electrical properties. This is hard and brittle. It resists flame, most solvents and sunlight. It is non-hygroscopic. PVC is widely used as insulation and jacketing material for cables and wires. PVC films, sheets and tapes are used as insulation for conduit pipes and dry batteries.
Permeability: The rate of diffusion of molten solid liquid and gases through refractories is called permeability. Low permeability is usually more important than low porosity from
leaching
compare boron and aluminium with carbon and silicon
Explain the mechanism of ferromagnetism Ferromagnetism is the basic mechanism by which certain materials (like iron) form permanent magnets and/or exhibit tough interactions
Laboratory staff and students Give an account of the permanent staff and students using the lab and for what purposes. Here you may use the concept of Laboratory Investigation
Daily routine of preparation for experiments/demonstration : In order to become familiar with the preparation that a lab staff member makes prior to an experiment/demonstration it
design a falling film evaporator in detail
Number of rooms, their size and allocation: Count the number of rooms including ancillaries (if any). Estimate their size and note the allocation of the main lab, preparatory room
Q. How can you measure the refractories and refractoriness under load of a refractory material?
The magnetic behavior of materials can be classified into the following five major groups: 1. Diamagnetism 2. Paramagnetism 3. Ferromagnetism 4. Ferrimagnetism 5. Antiferr
