What rubbish do plates and bowls belong to?
Hello! Plates and bowls are non-recyclable garbage. The following are the types of garbage classification: (1) recyclable garbage. It mainly includes waste paper, plastic, glass, metal, cloth and so on. (2) Non-recyclable garbage. Kitchen garbage and other garbage. Other wastes include ceramic tiles, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle except the above-mentioned types of garbage. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air. Plates and bowls belong to ceramics. Thanks for reading!
Why are ancient bricks and ceramics also silicates? (senior high school chemistry multiple-choice questions)
Yes, it's just slightly different from the current process, but the composition is similar, and they all belong to silicate products.
waste sorting
restorable
It mainly includes waste paper, plastic, glass, metal, cloth and so on.

Waste paper: mainly including newspapers, periodicals, books, various wrapping papers, etc. However, it should be noted that paper towels and toilet paper are too water-soluble to be recycled.
Plastics: all kinds of plastic bags, plastic foams, plastic packaging, disposable plastic lunch boxes and tableware, hard plastics, plastic toothbrushes, plastic cups, mineral water bottles, etc.
Glass: mainly includes all kinds of glass bottles, broken glass pieces, mirrors, thermos bottles and so on.
Metal objects: mainly including cans, cans, etc.
Cloth: mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc.
These wastes can be recycled through comprehensive treatment, reducing pollution and saving resources. If every 1 ton of waste paper is recycled, 850 kilograms of paper can be made, 300 kilograms of wood can be saved, and pollution is reduced by 74% compared with the same output; Every 1 ton plastic beverage bottle can recover 0.7 tons of secondary raw materials; Every recovered 1 ton of scrap steel can produce 0.9 tons of steel, which saves 47% cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.
Irretrievable
kitchen waste
Include food waste such as leftovers, bones, roots, leaves and peels.
Garbage classification catalogue
After in-situ treatment of compost by biotechnology, 0.6-0.7 tons of organic fertilizer can be produced per ton.
Other wastes
Including brick and tile ceramics, muck, toilet waste paper, paper towels and other difficult-to-recycle wastes, shells, dust, etc. except the above-mentioned kinds of garbage. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.
In fact, great bones are classified as "other rubbish" because they are "hard to corrode". Corn kernels, nut shells, fruit kernels and chicken bones are all kitchen waste.
toilet paper
Toilet paper and toilet paper are soluble in water and are not recyclable "paper". Similarly, there are pottery and cigarette cases.
Bagging of kitchen waste
Commonly used plastic bags, even though degradable, are far more difficult to corrode than kitchen waste. In addition, plastic bags themselves are recyclable garbage. The correct way is to dump the kitchen waste into the trash can and throw the plastic bag into the "recyclable garbage" bucket.
Nut shell
In garbage classification, the logo of "fruit shell and melon skin" is peanut shell, which really belongs to kitchen garbage. Waste cooking oil left at home is also classified as "kitchen garbage".
dust
In garbage classification, dust belongs to "other garbage" and litter belongs to "kitchen garbage", including flowers that have failed at home.
Toxic and hazardous waste
Waste containing heavy metals, toxic substances harmful to human health or actual or potential harm to the environment. Including batteries, fluorescent tubes, light bulbs, mercury thermometers, paint buckets, some household appliances, expired drugs, expired cosmetics and so on. These wastes are usually recycled or landfilled separately.
What do you mean by throwing bricks at porcelain? Is it good or not? How to judge the quality of ceramic tile?
1. Porcelain polished tiles are one of the innovative categories of ceramic wall and floor tiles. Its surface is made of porcelain material, printed and decorated, sintered at high temperature and polished. Compared with ceramic wall and floor tiles made of vitreous materials (such as glazed tiles and crystal tiles), it has higher wear resistance, warmer texture and more natural and realistic texture, and is suitable for interior and exterior wall decoration of various buildings. The concept of ceramic tile throwing machine was put forward by Hangzhou Nobel Group. With the authorized invention patents of related technologies and products, the whole-body digital ink-jet infiltrated ceramic tiles produced by it are typical representatives of ceramic tiles, which greatly improves the scientific and technological achievements and decoration technology of ceramic walls and tiles today.
Second, the characteristics of porcelain brick throwing:
1. Warm texture
The new porcelain surface material makes the porcelain surface moist and thick, and the surface texture is similar to granite and marble, but it is superior to ordinary stone in hardness and acid resistance.
2, imitation stone texture
Permeable ink-jet ink introduces auxiliary color materials into fabric, and adopts digital ink-jet infiltration technology to present a realistic stone-like texture in three-dimensional space.
3. Whole body texture
Tile throwing adopts new decoration technology and technology, and develops a perfect one-time cloth technology, so that the product has a perfect appearance. [2]
4. Wear-resistant and stain-resistant
Through the application of new materials, ceramic polished tiles have higher wear resistance and pollution resistance than ceramic wall and floor tiles made of glass (such as glazed tiles and polished crystal tiles).
Third, how to identify the quality of tile paving:
1, check the flatness of tile paving. You can use an aluminum alloy square tube (or other items that can be used for foot pads) with a length of about 2m on the pasted tile. If the surface energy of ceramic tile is closely seamless with the square pipe, it is a very qualified ceramic tile construction.
2, check the tile when the shop is stuck, through the appearance inspection of the tile, the joints are perpendicular to each other, the gap is uniform, the filling between the joints is not overflow or concave, and the joints between dense materials should meet the requirements.
3, check whether the tile shop is stuck empty drum phenomenon, hit the wooden handle with a stick or hammer, hold the stick with two fingers, while standing and walking, knock the center and periphery of each tile piece by piece, be sure to pay attention to it, and be sure to check it after 3 days of tiling. If the percussion sound is Sorakara Ku and the drum sound is empty, it sounds more solid and there is no problem. If the hollowing reaches 1/3 of the tile, then the tile needs to be pasted again, otherwise it will be easily damaged or fall off in the future.
What kind of rubbish do discarded plastic bags belong to?
Should be the main classification of recyclable garbage.
Recyclable garbage mainly includes waste paper, plastic, glass, metal and cloth.

Waste paper: mainly including newspapers, periodicals, books, various wrapping papers, etc. However, it should be noted that paper towels and toilet paper are too water-soluble to be recycled. [1] Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc. Metal objects: mainly including cans, cans, etc. Cloth: mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc.
Kitchen waste, including food waste such as leftovers, bones, roots, leaves and peels, can produce 0.3 tons of organic fertilizer per ton after in-situ treatment by biotechnology. Toxic and hazardous waste in hazardous waste refers to waste containing heavy metals and toxic substances that are harmful to human health or cause real or potential harm to the environment. Including batteries, fluorescent tubes, light bulbs, mercury thermometers, paint buckets, household appliances, expired drugs, expired cosmetics, etc. Other wastes in this paragraph include brick and tile ceramics, muck, toilet waste paper, paper towels and other refractory wastes. Usually, according to the characteristics of garbage, it is disposed by incineration or landfill.
What kind of rubbish is glass?
Glass is recyclable garbage.
Garbage belongs to the public's private articles in the stage of classified storage. After being classified by the public, it becomes a regional quasi-public resource in the community where the public is located, and it becomes a non-exclusive public resource after being classified and transported to the garbage concentration point or transfer station. Judging from the classification methods of municipal solid waste at home and abroad, it is generally classified according to the composition and output of garbage, combined with the resource utilization and treatment methods of local garbage.
Glass is a transparent solid at room temperature. When it melts, it forms a continuous network structure. During the cooling process, its viscosity gradually increases and hardens, and it will not crystallize. The chemical composition of ordinary glass is Na2O CaO 6SiO2, and the main component is silicon dioxide. Widely used in buildings, used for wind and shading, belonging to a mixture. There are colored glasses mixed with oxides or salts of certain metals to show colors, and tempered glasses made by special methods. Some transparent plastics (such as polymethyl methacrylate) are sometimes called plexiglass.
Timely glass, silicate glass, soda-lime glass, fluoride glass, high-temperature glass, high-pressure glass, ultraviolet-proof glass and explosion-proof glass. Usually refers to silicate glass, which is made of quartz sand, soda ash, feldspar and limestone through mixing, high-temperature melting, homogenization, processing and molding, and then annealing. Widely used in construction, daily use, medical treatment, chemistry, electronics, instrumentation, nuclear engineering and other fields.
