Today, with the development of urbanization, more and more buildings have risen and are spotlessly spotted. However, behind these magnificent high-rise buildings, how many people are silently giving away, but nobody knows that others are still being used by others. despise. They are doing the hardest and tiring most of their lives every day. However, their wages require them to save enough energy every day to use their lives, but not enough for their children to read. It can be imagined how difficult their children can go to school. When we walked past them, we couldn't wait to walk in one minute and fear that the rubbish was on my clothes. Remember to focus on reading garbage truck little boy with big eyes Heyao Ming it? That scene deeply impressed the white-collar youth Jiang Lusha, she was fixed by the camera, Xiao He was only fortunate enough to be concerned, and thus read the public primary school - Songgang first primary school. On March 16, 2010, Nandu reported that "the youngsters are busy reading on garbage trucks." In the blink of an eye six years later, Xiao He’s only toy basketball disappeared. The book became his only hobby, and the teacher praised him for his “deep†writing. However, he is about to graduate from elementary school because he does not have enough conditions to go to a private secondary school. Unbearable burden of tuition. For poor families, it is an insurmountable mountain. However, despite having difficulties for six years but insisting on not asking for help, Mama had to once again pull out the business cards of the Southern Reporters. Touching woman cleaners pushing a garbage truck while walking and sweeping, sitting on a small boy in the car and reading intently, not disturbing the bumps on the road and the bumps of the garbage truck on March 14th, 010am. White-collar youth Jiang Lusha went to work at the office on the 2nd floor of No. 176 Songming Avenue. He took a rest on the balcony and accidentally saw a female cleaner by the side of the road downstairs. She pushed a garbage truck and walked to sweep the floor. A little boy is reading intently, not at all disturbing the horns on the road and the bumps of garbage trucks. Jiang Lusha quickly took out the camera with her and took a picture of this touching scene. The little boy under the lens of Jiang Lusha is called He Yaoming, who was 6 and a half years old. The boy on the garbage truck is not the same with a lot of children of migrant workers did not book to read? Is it too poor at home to make him unable to learn? "The entire Songgang street district, the only firewood cooking I am afraid that only this family." In order to save money for children to read, Ho mother can only rent this 250 yuan a month house. Xiao Ming’s home is located in a cottage in an old village in Songgang. It was tattered and old. It turned out to be 6 years old. The Southern reporter once again saw the little boy He Yaoming. It was already May 16 this year. He Yaoming's home is in Wenwu Village, Songhe Road, Songgang Street, Bao’an District. It is near Bao’an Avenue and it is only two kilometers away from the Songgang Subdistrict office. At 11 o'clock in the morning, at a distance of about 100 meters from Hejia, you can see a metal house on which you can cook a meal. "The entire Songgang street area, the only firewood cooking I am afraid There is only this family," said Mr. Chen, the neighbor. Xiaoming's kitchen. Due to financial constraints, Xiaoming's mother still uses wood for cooking. She said that she could save a lot of gas money. The home is made up of two parts. Outside there is a wood-burning kitchen. Next to the waste wood is piled up into hills. Cheng Miaofang’s mother introduced that these firewoods were brought back to their own cleaning time and they had not been used up for 3 years. Xiao Ming and his mother sat in the middle of a messy house and used a cylinder to beat the table to eat breakfast. Xiao Ming’s mother said that he could cook some porridge on the weekend and it was a day. Later, the reporter asked Xiao Ming to know that he often drank porridge on weekdays. A lean boy sat reading in the doorway. The footsteps of other people did not allow him to look up and take a few more glances. When the Southern Reporter came to him, the little boy's head was lifted slightly and his mouth moved, but he did not know what to say. The tin house was divided into two layers. There were two beds in the room, a wooden bed and a iron frame bed, and a number of worn-out household items were piled up next to each other. He Yaoming said that most of these are mothers who have come back. "Mother feels that these may be useless afterwards. They are not willing to lose." In fact, the house rented by He Jia is a "plum" built with iron sheets. Compared with the majority of farmers' houses in the surrounding area that are more than 7 floors, they are somewhat out of place. In order to save money for children to study, you can only rent this 250 yuan a month house, but there are also many problems, but in the rain, there are several places in the house leaking water, "basin, buckets come in handy, used to Sheng water". Xiao Ming’s home, except for an open space in the middle, was filled with rubbish picked up by his mother from the outside, and even Xiao Ming’s homework was done. In the event of heavy rain, it leaked everywhere and was nowhere to be found. His mother also considered changing a house, but she couldn't bear the pile of wood. "If you use a gas stove, the gas fee for a year will be 2,500 yuan, which is equal to one month's salary, and you can't find the rent so cheap." House of". Although they built a home in Gaozhou, they still hope that their children can learn together with their parents. In addition to working at the Beiting school, his mother also contracted the sanitary cleaning of eight nearby rental houses and cleaned it once a week. In this way, we can earn another 800 yuan a month, and this job is done together with her son. The narrow corridor was hot and humid. Xiao Ming and his mother soon sweated, but the two were quietly swept away, fearing that their movements were too loud to wake up people living there. Upon seeing a guest visit, He Yaoming quickly took up his books, raised his stool, and returned to the house. He opened an incandescent lamp that had been exposed in the shell. However, the house still looked dark. At this time, Cheng Miaofang lay flat on a wooden bed and tied a small smoking box around her waist. She held her hands on the wooden planks and slowly sat up. Then she untied the small box, and He Yaoming hurriedly came to her mother. Supporting her around. Xiao Ming's mother had been suffering from rheumatism for many years. Her legs and feet were always in pain. In order to cure her illness but did not make too much money, Xiao Ming’s mother found some remedies and treated herself. After sitting down, Cheng Miaofang got out of bed and took out two small smoking boxes and skillfully bound the box to his knees. “Now, I’m old, my whole body is sick, I can't get up when my legs are down, I just smoke it. Better, but I have to smoke every day." Cheng Miaofang sighed. Cheng Miaofang said that when the child was 4 years old, his backaches began to falsify, and he wouldn't even bend over until mid-year. "Blindly sweeping the floor, you have to quit your job as a cleaner." Two years later, she was doing odd jobs. Cheng Miaofang’s illness is her lumbar disc herniation. She needs to go to the hospital for physical therapy every day. “The treatment fee is 50 yuan per day. It takes two months. I'm silly,†said Cheng Miaofang, and the symptomatic prescription was found. She is not willing to pay for treatment. Last year, a colleague recommended a treatment for her, that is, she bought AI to smoke, and she used a moxa to treat her waist and knee once or twice a day. Cheng Miaofang felt a little effect. Although her waist and knees still hurt, at least Stick to work, "Compared to the 50 yuan in the hospital, it takes only 3 yuan a day to burn with moxa." Cheng Miaofang said that he had never bought a toy for his son for six years, whether on his birthday or on Children's Day. He Yaoming wore a T-shirt and was very tight. Obviously, the size of the clothes was too small. Cheng Miaofang frankly stated that the clothes he wore are also sent by colleagues from Beiting Elementary School two years ago. They have not bought him for more than a year. New clothes, last year, when her mother was sick and returned to her hometown to see her, she bought two short-sleeved sportswear for her daughter. The two sets added up to less than 130 yuan. He Yaoming said that she was "a woman who was a girl." In fact, these are only the tip of the iceberg of the people living on the bottom. They are only a small dust in the corner of the iceberg. Whenever we pass by them, we should not look at them with contempt. They should take the initiative to help them so that the world can be even better.
Powder coating is a dry finishing process that has become extremely popular. Powder coating is used on a wide array of products. More and more companies specify powder coatings for a high-quality, durable finish, allowing for maximized production, improved efficiencies, and simplified environmental compliance. Used as functional (protective) and decorative finishes, powder coatings are available in an almost limitless range of colors and textures, and technological advancements have resulted in excellent performance properties.
Advantages over other coating processes
1. Environment friendly. Powder coatings contain no solvents and release little or no amount of volatile organic compounds (VOC) into the atmosphere.
2. More thicker coatings without running or sagging than conventional liquid coatings.
3. Perfect color consistency. Powder coated items generally have fewer appearance differences than liquid coated items between horizontally coated surfaces and vertically coated surfaces.
4. A wide range of speciality effects are easily accomplished using powder coatings that would be impossible to achieve with other coating processes.
5. Curing time is significantly faster with powder coatings compared to liquid coatings especially when using ultraviolet cured powder coatings or advanced low bake thermosetting powders.
Powder Coating Process
The Powder coating process involves three basic steps: raw material preparation or the pre-treatment, the powder coating application and curing.
Powder Coating Substrate Considerations
Before applying the powder coating material, you must first consider the substrate material that you will be coating. It is very important to have a clear understanding of the true composition of the surface of the part.

Gloss is measured as a percentage.
1. Matt Powders are between 20% and 30% gloss.
2. Semi-gloss Powders are usually around 60-65% gloss.
3. Gloss Powders at least 80% and can be 85%.
Powder Coating finishes
1. Textured Powder Coating:
2. Ripple/Leatherette Powder Coating.
3. Hammerite Finish Powder Coating.
4. High Temperature Powder Coating.
5. Anti-Bacterial Powder Coating.
6. Clear or Tinted Powder Coatings.
Application Field
1. In automotive applications:
a) some primers used on bodywork have converted to powder. This has given improved coating quality and provided ecological advantages.
b) where a functional as well as a decorative finish is desirable powder coatings are being used increasingly eg.
i. - wheels,
ii. - bumper bars,
iii. - mirror frames,
iv. - oil filters,
v. - battery trays,
vi. - coil springs and
vii. - heads.
2. Appliances
a) Specially formulated, hard and scratch resistant powder coatings are replacing the energy-intensive porcelain finishes on washer tops and lids.
b) Powder coatings are being used on range housings, freezer cabinets, drier drums, and microwave oven cavities.
c) Outdoor furniture, farm and garden implements and garden tractors also are being finished with powder coating materials. - Interior fluorescent light reflectors are coated using a highly reflective, very thin powder coating.
d) Exterior lamp housings on highway and parking deck fixtures are coated with specially formulated powder which give ultra violet light protection and added corrosion protection
