Q:What affects plastic ?
Whether a polymer is affected by acids depends on the type of polymer. Polyethylene and similar compounds with carbon-carbon polymerisation from double-bond monomeres are mostly immune to acid (with polyvinyl-alcohol and to a lesser degree polyvinyl-acetate notable exceptions). Polymers with a peptide or ester bond are very vulnerable towards acid, e.g. nylon, perlon... Polycarbonate and polyurethanes are potentially destroyed by strong acids, too.
Q:Some kinds of plastic wrap can be stretched tightly over a container and down its sides. The plastic wrap sticks to the sides of the container? Why?
most kitchen plastic wrap is made of low density polyethylene, also known as LDPE. This plastic makes a good barrier to water and air, but it does not stick to itself. To make it cling, they add another chemical, such as polyisobutylene or poly[ethylene-vinylacetate]. These chemicals do not mix totally with the LDPE. Instead, they act like the adhesive on tape, only not as sticky, and it only sticks to certain things. Want to see? Try sticking it to paper, different plastics, wood, and other substances. Then you will know why the plastic wrap will stick easily to some containers, but not to others. If it will not stick, then you just have to make room to eat that last piece of pie, right?
Q:Help me I need information aboutFlow length process for plastic bottle ?bottle wall thickness?
Different plastics have different melting points and different temps where they will flow.. pet pvc pp 160 160 220 Fahrenheit Some bottles are made all at once and some in a two step process. (first a preform then the bottle) Saw several videos on YouTube making plastic bottles. just cut a bottle of interest and measure the wall with a micrometer.
Q:Can agricultural plastic products be used for soilless cultivation?
Yes, agricultural plastic products can be used for soilless cultivation. Soilless cultivation refers to the practice of growing plants without the use of traditional soil. Instead, various growing media such as coco coir, perlite, or rockwool are used. Agricultural plastic products like pots, trays, and mulch films can be effectively used in soilless cultivation systems to support and nurture the plants. These plastic products provide a sterile and controlled environment for plant growth, facilitate nutrient uptake, and help retain moisture, resulting in successful soilless cultivation.
Q:Not bioplast - just general plastic!
Plastics/acrylics shouldn't be in contact with your piercing for an extended period of time, and should only be used cosmetically rather than as a standard tongue bar. Acrylics in particular are quite toxic to the human body. Your piercing should be fully healed before you even consider changing it to anything that isn't implant grade, and if you're going to keep the plastic bar in for long, it would definitely be advisable to put purchase something in bioplast or PTFE to keep your piercing happy and healthy! You can normally pick them up in several designs for a cheap price.
Q:just like people can taste difference between coke and pepsi and the diet variations of each, i notice a difference in cider from a can to cider from a plastic bottle. Cider from a plastic bottle doesnt seem to taste as nice as from a can or glass bottle or on tap from a pub.will using a plastic demijohn when home brewing cider damage the taste compared to a glass demijohn?
NO plastic is inert like glass...only cheaper and less fragile
Q:Are nursery trays suitable for water lilies?
No, nursery trays are not suitable for water lilies as they typically require larger containers or ponds with the proper depth and space for their roots to grow and spread.
Q:How do agricultural plastic products aid in seed germination?
Agricultural plastic products aid in seed germination by providing a controlled environment that promotes optimal conditions for seed growth. These products, such as plastic mulch films or seedling trays, help retain soil moisture, regulate soil temperature, and protect seeds from pests and diseases. By creating a favorable microclimate, agricultural plastic products enhance germination rates and improve overall seedling health, leading to successful crop production.
Q:Plastic and fingernail, which is harder?I am trying to know if I use my fingernail to scratch a plastic material. Which will being scratched off?
It depends on which plastic you're talking about. Different plastics have different hardnesses, and some will be scratched by a fingernail, while others will not. Check to see if you can find what the material is made of. Usually plastics will have an acronym printed on them that gives the chemical name - common ones are PE (polyethylene), PS (polystyrene), PVC (poly vinyl chloride), PMMA (polymethyl methacrylate), etc. Once you know the chemical name, try checking wikipedia on that compound or typing in the name of the plastic and Mohs hardness or hardness into Google. Oh. Also, the Mohs hardness of a fingernail is 2.5. The scale goes from 1 to 10, talc being a 1 and diamond being a 10.
Q:Are there nursery trays with built-in heating elements?
Yes, there are nursery trays available with built-in heating elements. These trays are designed to provide a controlled and consistent temperature for the optimal growth of plants and seedlings. The heating elements help create a warm and nurturing environment, which promotes germination and healthy root development.
