The thermometer is the general name of the temperature measuring instrument and can accurately determine and measure the temperature. The use of solids, liquids, and gases under the influence of temperature, such as thermal expansion and contraction, is the basis of planning. There are various kinds of thermometers, such as kerosene thermometer, alcohol thermometer, mercury thermometer, gas thermometer, resistance thermometer, thermocouple thermometer 1, radiation thermometer and photometric thermometer, bimetal thermometer, etc., but we must pay attention to the correct method of use. Wenyi's relevant features facilitate better use.

Application of Bimetal Thermometers The principle of homogenous conductors consists of a homogeneous loop consisting of a homogeneous conductor. No matter how the temperature is distributed along the length of the material, no thermoelectric potential is generated in the loop. Conversely, if there is a thermoelectric potential in the loop, When present, the material must be non-homogeneous. The intermediate conductor rule inserts a third (or more) homogeneous material in the thermocouple circuit, as long as the connecting point at both ends of the accessed material has the same temperature, the access The third material does not affect the original circuit's thermoelectric potential. Proof of the intermediate temperature rule of thermocouple circuit consisting of two different materials, the junction temperature is t and t0 thermoelectric power EAB (t, t0) equal to the thermocouple in The junction temperature is (t, tn) and (tn, t0) corresponding to the sum of the algebraic sums of the thermoelectric sums, where tn is the intermediate temperature.
Allowable errors are about 1% of the scale range. This thermometer is similar to a rod-shaped glass liquid thermometer, but it can be used under higher mechanical strength requirements. Features Temperature display on the spot, intuitive and convenient, safe and reliable, long service life; core-pull thermometer can maintain or replace the movement without stopping the machine for a short time. Axial type, radial type, 135o type, universal type and other varieties are complete, suitable for a variety of on-site installation needs. The application instrument accuracy grade reaches 1.0, and the upper shell of the instrument adopts anti-corrosion material.
Bimetal thermometer is a kind of on-site measuring instrument for measuring medium and low temperature. It can directly measure the temperature of liquid vapor and gas medium in the range of -80°C-+500°C in various production processes. The main component of an industrial bimetal thermometer is a multi-layer metal sheet consisting of two or more metal sheets laminated together, using the principle that two different metals expand differently when the temperature changes. It is based on a bimetallic strip wound into a loop shape.

Below different plastic waste could be recycled into diesel:
Plastic pipes, plastic films, farm films, nylon, plastic convenient bags, HDPE bottles, bottle caps, food packaging...etc.
Different waste plastic has different oil yield and different oil quality.
If want to get diesel, need set up Plastic Pyrolysis Equipment and Distillation Equipment.
