PV fuses are utilised to protect solar power gathering equipment against overcurrents, reserse currents and short circuits that can occur within alternative energy gathering PV string installations. Photovoltaic (PV) fuses vary in a number of different ways including fuse speed, voltage and amperage rating, breaking capacity and their physical […] Ver

    A drinking straw is a utensil that is intended to carry the contents of a beverage to one’s mouth. Straws are commonly made from plastics but environmental concerns and new regulation have led to rise in reusable and biodegradable straws. These straws are often made of silicone, cardboard, or metal. A straw is used by placing one end in one’s mouth and the other in a beverage. By employing suction, the air pressure in one’s mouth drops causing atmospheric pressure to force the liquid through the straw and into the mouth. Drinking straws can be straight or have an angle-adjustable bellows segment. Drinking straws have historically been intended as a single-use product and several countries, regions, and municipalities have banned single-use plastic straws to reduce plastic pollution. Additionally, some companies have even voluntarily banned or reduced the number of plastic straws distributed from their premises. Paper straws, as the name suggests, are made of paper and are degradable. Beginning on January 1, 2021, the beverage industry responded to the national “plastic ban on straws” and replaced paper straws and PLA (biodegradable) straws. In mid-January, due to taste and other reasons, the industry upgraded paper straws to PLA straws. Paper straws are generally made of virgin paper and food wax. Advantages: 1. Environmentally friendly, recyclable and easy to degrade; 2. Safe, no precipitation of harmful chemical elements; 3. User-friendly, no sharp burrs, etc. Disadvantages of injury: 1. High cost; 2. Hot drinks are easy to dissolve; 3. Hot-sealed drinks cannot directly pierce the cover; 4. It has a shelf life and has requirements for the preservation environment. Paper straws are mainly of great significance to environmental protection.

    Sugarcane cutlery includes a lot, such as Biodegradable Soup Spoon, Disposable Knife Fork and Spoon, Non Plastic Disposable Cutlery, Paper Fork and Spoon, etc. Biodegradable spoon refers to spoons that can undergo biochemical reactions under the action of microorganisms (bacteria, molds, algae) and enzymes in the natural environment, causing mildew in appearance to change in internal quality, and finally forms carbon dioxide and water. It uses two kinds of materials: one is made of natural materials, such as paper products, straw, starch, etc., which are degradable, and are also called environmentally friendly products; the other is plastic as the main component, adding starch, photosensitive agent and other substances. GB18006.3-2020 “General Technical Requirements for Disposable Degradable Tableware” has stricter requirements for tableware that can be marked as “degradable”. For example, the biodegradation rate must reach more than 60%, and the starch content of degradable tableware with starch components must not be low. At present, most of the degradable tableware manufacturers in China can meet the above standards.

    Disposable spoons are divided into the following three categories according to the source of raw materials, production process, degradation method and recycling level: 1. Biodegradable categories: such as paper products (including pulp molding type, cardboard coating type), edible powder molding type, Plant fiber molding type, etc.; 2. Light/biodegradable materials: light/biodegradable plastic (non-foaming) types, such as photobiodegradable PP; 3. Easy-to-recycle materials: such as polypropylene (PP) ), high impact polystyrene (HIPS), biaxially oriented polystyrene (BOPS), natural inorganic mineral filled polypropylene composite products, etc. With the continuous improvement of people’s living standards, various disposable paper daily necessities emerge in an endless stream, and many kinds of household paper used in different occasions have been introduced. In China, the penetration rate of disposable paper products, especially toilet paper and feminine hygiene products, is much higher in first-tier cities than in second- and third-tier cities and rural areas. Zhiyan Data Research Center said that with the saturation of disposable paper products in developed urban markets, second- and third-tier cities and rural areas have become new market growth areas.
