The production process of smart scoops has mainly undergone several development stages: solvent method, solution method, liquid phase bulk method (including liquid phase and gas phase combination) and gas phase method. The process methods used to produce smart scoops are divided into the following major categories Types: solvent method, solution method, liquid phase bulk method (including combined liquid phase and gas phase) and gas phase method. Next, we will introduce the advantages of using smart scoops.
Here is the content list:
What is the production principle of smart scoops?
Smart scoops material has superior chemical properties
What are the outstanding advantages of using smart scoops?
The melt viscosity of PP is relatively low, so the molding process has good fluidity, especially when the melt flow rate is high, the melt viscosity is smaller, which is suitable for injection molding of large thin-walled products. After the PP leaves the die, if it is slowly cooled in the air, larger crystal grains will be generated and the product transparency will be low.
Because of the plasticity of smart scoops, polypropylene materials are gradually replacing wooden products, and high strength, toughness and high wear resistance have gradually replaced the mechanical functions of metals. In addition, smart scoops have good grafting and compounding functions, and have huge application space in concrete, textile, packaging, agriculture, forestry and fishery.
Smart scoops, PP transparent plastic scoop 15G, used for ice cream powder, polypropylene for short PP, is a colorless, odorless, non-toxic, translucent solid substance. Polypropylene (PP) is a kind of thermoplastic synthetic resin with excellent performance. It is a colorless and translucent thermoplastic lightweight general-purpose plastic. Therefore, the smart scoops made have extremely high practical value.
The material of smart scoops has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high abrasion-resistant processing performance. This has made polypropylene quickly used in machinery, automobiles, electronics, construction , Textiles, packaging, agriculture, forestry, fishery and food industry have been widely developed and applied.
①Smart scoops have good heat resistance. Its melting point is 164-170 degrees. It can be boiled and steam sterilized in water. It can also be used for a long time at 100 degrees without deformation.
②Smart scoops general-purpose plastic PP has high gloss and transparency, good mechanical strength, odorless, tasteless, non-toxic, and meets national health standards.
③Smart scoops has excellent corrosion resistance, and its oxidation resistance is slightly worse than polyethylene.
④Smart scoops are inexpensive and have a wide range of applications.
⑤Smart scoops have good bending fatigue resistance, and can be reciprocated more than 1 million times at 0 degrees without damage.

Physical properties: smart scoops is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of only 0.90~.091g/cm3, which is one of the lightest varieties of all plastics.
Mechanical properties: Smart scoops has high crystallinity and regular structure, so it has excellent mechanical properties. Its strength, hardness and elasticity are higher than HDPE, but at room temperature and low temperature, due to its high molecular structure regularity, so the impact strength Inferior, when the molecular weight increases, the impact strength also increases, but the molding processability deteriorates. The most outstanding performance of smart scoops PP is its resistance to bending fatigue.
Thermal performance: smart scoops PP has good heat resistance, melting point is 164~170℃, products can be sterilized at temperatures above 100℃, and will not deform at 150℃ without external force. The embrittlement temperature is -35℃, embrittlement will occur below -35℃, and the cold resistance is not as good as polyethylene;
Chemical stability: The chemical stability of smart scoops is very good. In addition to being corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can make PP softens and swells, and the chemical stability of smart scoops increases with the increase of crystallinity.
Electrical properties: smart scoops has excellent high-frequency insulation properties. Because it hardly absorbs water, the insulation properties are not affected by humidity. It has a high dielectric coefficient, and with the rise of temperature, it can be used to make heated electrical insulation products. Its breakdown voltage is also high, and it is suitable for electrical accessories. Good voltage resistance and arc resistance, but high static electricity, easy to age when contacted with copper;
Weather resistance: smart scoops are very sensitive to ultraviolet rays. Adding zinc oxide, dilauryl thiopropionate, carbon black or similar milky white fillers can improve its aging resistance.
