Liquid resols of phenol formaldehyde resin can be stored for longer time. Free formaldehyde needs to be controlled at the end of the reaction. This will be possible by adding formaldehyde scavanegers. The pH of reaction is most important in this regard. Adjust the pH of the PF resin to 7 to 7.5 using acid such as acetic acid to increase in shelf lift. Some resols can be stored up to 6 months below 25 deg C.

What is a process that solidifies and stabilizes liquid oils?
Hydrogenation is a process that solidifies and stabilizes liquid oils by adding hydrogen atoms to unsaturated fats to make them more saturated. This process helps to increase the shelf life and enhance the texture of the oil, making it suitable for various food applications.
How does the sticky fluid produced in female cones affect the conifer life cycle?
The sticky fluid produced in female cones, often referred to as resin, plays a crucial role in the conifer life cycle by aiding in the protection and dispersal of seeds. This resin helps to seal and protect the seeds from pathogens and herbivores, enhancing their chances of survival. Additionally, the sticky substance can facilitate the attachment of pollen, which is essential for fertilization, ensuring successful reproduction. Ultimately, this resin contributes to the overall fitness and resilience of conifer species in their environments.
When can you increase the flow rate of a fluid in your daily life?
The flow rate of a fliud or liquid could be increased (depending on the situation) by increasing the amount of the fluid, then channelising this fluid into a narrow channel.
How do waters relative densities as a solid and a liquid differ as a solid and a liquid differ from that of most other substances?
Water's density as a solid (ice) is lower than its density as a liquid, which is unusual compared to most substances that become denser when solidified. This unique property causes ice to float on liquid water, providing insulation for aquatic life below. Most other substances, like metals, increase in density when they transition from liquid to solid. This characteristic of water is crucial for the environment and climate, as it affects ocean currents and the stability of ecosystems.

What does an increase in temperature result to?
An increase in temperature can lead to the expansion of materials, a change in state (for example, from solid to liquid), an increase in the speed of chemical reactions, and can also cause biological processes to speed up or slow down.
Liquid of life term is for what?
" Liquid of life " is a term made for water.
Why does your 8 year old daughter shake her head for no resin?
Its part of growing up in life.
Do all living cells exist in liquid environments?
Life as we know it depends on liquid water to sustain life.
What is a metaphor for liquid?
life is like liquid slipping through your hands.

Repairing Resin Wicker Patio Furniture?
Resin wicker patio furniture is a durable and inexpensive alternative to other types of outdoor furniture. The resin material can be easily cleaned with household products and can be washed with a garden hose. In cases where there is a stain that will not come out or some damage, the resin coating can be gently sanded down with sand paper until a clear area is revealed. This cleaned section can then be coated in wax to restore the finish and extend the life of the patio furniture.
What will affect the rate of evaporation?
Assuming you are referring to a liquid exposed to air, then the factors affecting the evaporation are the temperature, and the air pressure. In a real-life situation, the presence of waves would also increase the evaporation rate.
Where did ancient egyptians get oil and resin?
Ancient Egyptians obtained oil and resin primarily from plants and trees native to their region. They sourced oils from seeds, such as sesame and castor, as well as from fruits like olives. Resin, particularly from the mastic tree and other aromatic plants, was harvested for use in perfumes, embalming, and rituals. These natural resources were integral to their daily life, religion, and trade.
Why do reactivity test in unsaturated polyester resin?
Reactivity tests in unsaturated polyester resin are conducted to evaluate the resin's curing behavior, stability, and performance under different conditions. These tests help determine the optimal conditions for polymerization, including temperature and catalyst concentration, ensuring effective cross-linking and final material properties. Additionally, they assess the resin's compatibility with various fillers and additives, which is crucial for achieving desired mechanical and thermal characteristics in the final product. Understanding reactivity also aids in predicting the shelf life and processing conditions necessary for the resin's application.
