- 09-12 How to choose a kitchen electronic scale Classification 1. According to the purpose: household kitchen scales and hotel kitchen scales.2. According to the sensing points: electronic kitchen scales and mechanical kitchen scales.3. According to food raw materials: liquid measuring kitchen scale and quality measuring kitchen scale.4. According to the finished food products: Western-style pastry kitchen scales and Chinese food kitchen scales.Through the second point, we know the classification of kitchen scales, which helps us choose the kitchen scale that suits us. General household kitchen scales require lower accuracy than hotels; Chinese-style measurement accuracy is lower than Western-style pastry measurement accuracy. Moreover, mechanical kitchen scales are generally divided into 1kg, 2kg, 3kg and 5kg, and the accuracy is at least 5g, which is suitable for occasions with low precision requirements. Electronic kitchen scales generally have a weighing range of 5KG, and the minimum accuracy is 0.1g. 2 AA (No. 5) dry batteries are commonly used in the market. In the early days, CR2032 button batteries were built in (can be bought in computer markets or watch stores, computer motherboard batteries It is this kind of battery) has been gradually phased out. Generally speaking, an electronic scale has only one range and accuracy. Kitchen scales with different ranges have relatively different accuracy, such as 5kg*1g, 7kg*1g, 3kg*0.5g, 2kg*0.1g, 1kg*0.2g, 500g*0.1g.The appropriate range and accuracy can be selected according to your requirements.
- 09-12 The principle of reflective clothing The reflective part of the reflective clothing is made by using the principle of refraction and high-refractive-index glass micro-bead retro-reflection, and is made by advanced technology after focusing. It can reflect the direct light from a distance back to the light-emitting place, and has good retro-reflection optical performance in day or night. Especially at night, it can exert the same high visibility as during the day. Safety suits made of this high-visibility reflective material can be easily spotted by night drivers regardless of whether the wearer is far away or in the presence of light or scattered light. The emergence of reflective materials has successfully solved the night driving problem of "seeing" and "being seen".
- 09-12 What is a diamond saw blade? Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone materials, and ceramics. The diamond saw blade is mainly composed of two parts; the base body and the cutter head. The base body is the main support part of the bonded cutter head.The cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, but the matrix will not. The reason why the cutter head can cut is because it contains diamond, and diamond is the most important part. A hard substance that rubs and cuts the workpiece in the cutter head. The diamond particles are wrapped by metal inside the cutter head.

Hand tools can be divided into wrenches, pliers, screwdrivers, tape measures, hammers, sockets, cuttings, scissors, sets, and auxiliary tools such as tool carts, etc., each category is different 's model.The wrenches include open-end wrenches (rigid hands), double-prong wrenches, ratchet wrenches (quick wrenches), dual-purpose wrenches (composite wrenches), tubing wrenches, T-socket wrenches, cross-socket wrenches, adjustable wrenches and other categories;Pliers include wire pliers, needle nose pliers, diagonal nose pliers, retaining ring pliers, carp pliers, water pump pliers, pipe pliers, strong pliers and other categories;The screwdriver has a character, a cross, a rice character, a hexagon, a pattern and other categories;The sleeves are divided into ordinary sleeves, flower sleeves (E-type sleeves), screwdriver sleeves (BIT sleeves), spark plug sleeves, strong sleeves, etc. According to the specifications, there are three common specifications: 1/4", 3/8" and 1/2", " is the representation of inches; at the same time, each specification is divided into 6 angle sleeves and 12 angle sleeves;Hammers are divided into claw hammer, fitter hammer, round head hammer, rubber hammer and installation hammer;Cutting categories include files, diamond files, iron shears, aviation shears, utility knives, square pipe saws, pipe cutters, wire breakers, etc.;In terms of materials, there are Luo vanadium steel, carbon steel, alloy steel and so on.
