Solution:
First, clean with tap water, then add disinfectant with a slightly higher concentration, and then rinse with clear water. Soak for half a day, and finally soak in boiling water. Everything is as good as new.
When building materials shops turn around, there is a special cleaner for cleaning glass.
Question 2: How to remove the yellowing of plexiglass is because of oil stains in the air and alkali in water vapor, such as scale. In addition, if glass glue is added to the glass or its surface, it will deteriorate and yellow after being irradiated by sunlight.
Solution:
First, clean with tap water, then add disinfectant with a slightly higher concentration, and then rinse with clear water. Soak for half a day, and finally soak in boiling water. Everything is as good as new.
Take a look around the building materials store. There is a cleaner for cleaning glass. I don't know where you are. There is one near Shengzhixiang here in Xiamen.
question 3: what should I do if acrylic turns yellow? According to what you said, your sculpture fountain made of acrylic is not really acrylic. If it is true, it can be cleaned with toothpaste. In addition, these chemical products are afraid of acid and cannot be cleaned with toilet cleaner. Acrylic is the best new material to make sanitary ware after ceramics. As a special plexiglass, acrylic can also be used in aircraft windshields and used in harsh environments for decades. Compared with traditional ceramic materials, acrylic has the following advantages besides unparalleled high brightness: good toughness and not easy to be damaged; Strong restorability, as long as you dip toothpaste with soft foam, you can wipe the sanitary ware; Soft texture, no cold and biting feeling in winter; Bright colors can meet the individual pursuit of different tastes. The basin, bathtub and toilet made of acrylic are not only exquisite in style and durable, but also environmentally friendly, and their radiation level is almost the same as that of human bones. Acrylic sanitary ware first appeared in the United States, and now it has occupied more than 7% of the whole international market. In China, Sichuan Dongfang Sanitary Ware Factory took the lead in introducing this technology from abroad and applied for a registered patent in China. Now, domestic acrylic sanitary ware brands such as "Emperor" and "Jazz" are also favored by more and more consumers. Because of the difficulty and high cost of acrylic production, there are many substitutes with low quality and low price in the market. These substitutes, also known as "acrylic", are actually ordinary organic boards or composite boards (also known as sandwich boards). Ordinary plexiglass board is cast with ordinary plexiglass cracking material and pigment, which has low surface hardness and is easy to fade, and the polishing effect is poor after being polished with fine sand. The composite board only has a thin layer of acrylic with ABS plastic in the middle, which is easy to delaminate due to thermal expansion and cold contraction in use. True and false acrylic can be identified from the subtle color difference and polishing effect of the plate section.
question 4: how to deal with the yellowing of acrylic board? The solution of urgent 5 points can generally be wiped with toothpaste. Note that these chemical products are afraid of acid and cannot be cleaned with toilet cleaner.
there are three kinds of materials: brand-new materials, semi-new materials and recycled materials.
How to tell the true and false acrylic:
1. Due to the difficulty and high cost of acrylic production, there are many low-quality and cheap substitutes in the market. These substitutes, also known as "acrylic", are actually ordinary organic boards or composite boards (also known as sandwich boards). Ordinary plexiglass board is cast with ordinary plexiglass cracking material and pigment, which has low surface hardness and is easy to fade, and the polishing effect is poor after being polished with fine sand.
2. Acrylic first appeared in the United States, and now it has occupied more than 7% of the whole international market. In China, Tianyilong is the first to introduce this technology from abroad and apply for a registered patent in China.
3. The composite board only has a thin layer of acrylic with ABS plastic in the middle, which is easy to delaminate due to thermal expansion and contraction. True and false acrylic can be identified from the subtle color difference and polishing effect of the plate section.
Question 5: Will the plexiglass crack and yellow after a long time? It depends on how long it takes.
If it is a brand-new material board, it can be guaranteed not to yellow for five years, and it will not crack without strong impact.
If it is returned to the material board, it can be guaranteed not to yellow and crack without external impact for one year, but the impact force that it can withstand is less than that of the new material board.
Question 6: How to polish plexiglass requires high transparency. Because plexiglass is plastic, its hardness is not great, and it will slowly age and yellow with time. I suggest you choose imported plexiglass, which has high transparency and good strength.
PMMA is a popular name, abbreviated as PMMA. The chemical name of this polymer transparent material is polymethyl methacrylate, which is a polymer compound polymerized from methyl methacrylate. It is an important thermoplastic developed earlier. Plexiglass can be divided into colorless transparent, colored transparent, pearlescent and embossed plexiglass. Plexiglass, commonly known as acrylic, acrylic and acrylic, has the advantages of good transparency, chemical stability, mechanical properties and weather resistance, easy dyeing, easy processing and beautiful appearance. Plexiglass is also called gelatin glass, acrylic and so on.
Question 7: After drilling the hole, the plexiglass will turn yellow after a long time. How to deal with the yellowing of the plexiglass after drilling? The main reason is that the rotating speed is too fast during drilling, which is caused by heat. Treatment methods:
1. Slow down the speed when drilling and add water to cool down to avoid the yellowing of the hole caused by high temperature.
2. After yellowing, you can clean it with tap water or soak it with appropriate disinfectant.
3. At present, there are special glass cleaning agents in the market, spray type, which are very effective for spraying yellow parts.
question 8: how to deal with the yellowing of plexiglass? The yellowing of plexiglass is due to oil pollution in the air and alkali in water vapor, such as scale. In addition, if glass glue is added to the glass or its surface, it will deteriorate and yellow after being irradiated by sunlight.
Solution:
First, clean with tap water, then add disinfectant with a slightly higher concentration, and then rinse with clear water. Soak for half a day, and finally soak in boiling water. Everything is as good as new.
