[Moisture -proof paper] How to choose the principle of moisture -proof paper to purchase moisture -proof paper

principle of moisture -proof paper

1. It is a wrapping paper made of asphalt in the middle of the two layers of original paper.It is mainly used for cigarette cigarettes and can also be used as fruit packaging.The moisture -proof paper has a certain moisture -proof ability. The minimum moisture -proof rate is above 15%. The good moisture -proof paper is uniform and the bonding is firm.It has odor to avoid affecting the quality of cigarettes, but the paper packaging cigarette is no longer used.

2. To prevent moisture, moisture -proof is to prevent the humidity in the air from being too high. Excessive humidity of the air will cause mold to breed quickly. Moisturizers can not only make items moldy, but also make the elderly and children infected with various diseases.Economic losses caused by humidity and mildew are as high as hundreds of billions of dollars due to humidity and mildew.

How to choose a moisture -proof paper

1. Buy stickers based on wear resistance: The strength of the degree of wear resistance can directly reflect the quality of the stickers.The high -quality high -quality stickers can be simply scrubbed and after scrubbing, it has no effect on the overall. On the other hand, some inferior stickers will be damaged or water stains.Therefore, when choosing, use a pencil to draw on the selected sticker, and then rub it with rubber. After the rubbing, there is no trace for the superior quality, leaving traces as a secondary product.

2. Buy stickers according to the packaging: Choose the entire details of the wallpaper when selecting stickers. Generally, good quality stickers will be meticulous in packaging and marks, and will never give the defect opportunities.And generally paying attention to quality companies will adhere to the concept of "simplicity and simplicity", they will make their packaging look simple but not atmospheric.

3. Buy stickers from the environmental protection index: Whether the environmental protection is environmentally friendly is very related to our physical health. When choosing a sticker, you can first look at the sticker. It is best to burn a small section on the spot.The wallpaper is fully burned and has no pungent taste and smoke.

4. Many people do not know that mold is caused by the high humidity of the air.Scientific research shows that when the temperature of the home environment is between 25 C-30 C and the relative humidity exceeds 60%RH, the oxygen in the air is very sufficient. At this time, the mold will be extremely active and will quickly reproduce.Therefore, every year in the rainy season, the troubles brought by mold will erode people's lives widely.In tropical, subtropical, and temperate areas, especially coastal areas, mold problems caused by humidity are bothering people's lives all year round.According to statistics, economic losses caused by humidity and mildews each year are as high as hundreds of billions of dollars (only referring to family aspects).There are many types of moisture -proof beaded molds, including the subcortes, algae bacteria, and incomplete bacteria outlines in the fungal door.Mold spread mainly relies on spores. The spores are tiny powder, and it is not easy to observe with the naked eye.Because of its small size and light weight, it can float around with the movement of air flow, dust, human body and objects.

5. During the flow, once a suitable environment (temperature and humidity) encounters a suitable development, it will grow and reproduce immediately.The length, taste and deformation of the items happened.The mildew of the items causes the item to be damaged and feels uncomfortable, and the severe health will affect the health of the family (leading to Skin diseases and food poisoning), especially the harm of infants and elderly people with weak resistance.Essence

1. What is the scope of the lawn Lights?

Lawsticks are a kind of outdoor lamps, which are mainly used for decorative lighting of green belts in parks, garden villas, Square greening, and other places. It provides the effect of lighting embellishment lighting at night at night. How much can the lawn Lights be exposed?

Because the light source installation method of the lawn Lights is not the same as the lighting method, there is no fixed irradiation range value. The specific ones can contact the manufacturer to provide the corresponding style or custom design and production according to actual needs.

2. How much is the spacing spacing of lawn Lights?

When installing the lawn Lights, the problem of installation is needed. If it is too dense, it will look stiff. It is too thin and cannot give full play to the effects of lighting and decoration. So how much is the gap between the lawn light?

Generally speaking, most of the lawn lamps are more common at corners, trails or corners of light. The installation spacing is mainly different according to the light source and height:

1. Under normal circumstances, lawn Lights are needed for environmental decoration and travel. The installation spacing is about 6 to 8 meters; if 36W or 70W gold halogen Lights and sodium Lights are used, it can be relaxed to 10m spacing.

2, a 0.5 -meter -high lawn light, uses a energy -saving light of about 23W as the light source, can be farther away, about 11 meters.

3. The 3.5-meter-high lawn Lights are generally regarded as courtyard Lights. The light source is 15-30W, and the spacing can be set between 8-12 meters.

The above is a spacing design under normal circumstances. It can be appropriately encrypted near the steps, grass, corners, and flower platforms. While beautifying the environment, it also guarantees the safety of people walking at night.In addition, it is important to note that if it is a Solar lawn light, in order to prevent the weather from unsatisfactory weather conditions, it is necessary to choose auxiliary electricity to achieve lighting, and pay attention to the size of the distance.
