Polyvinyl chloride (PVC) paste resin, as the name suggests, is mainly used in the form of paste, which is often referred to as plasticized paste, which is a unique liquid form of polyvinyl chloride plastic in the unprocessed state. Paste resins are often prepared by emulsion and microsuspension methods.
Due to its fine particle size, the texture of polyvinyl chloride paste resin is like talcum powder and has immobility. PVC paste resin is mixed with plasticizer and stirred to form a stable suspension, that is, PVC paste, or PVC plasticizer paste, PVC sol, and people are used to process it into final products in this form. In the paste-making process, according to the needs of different products, various fillers, diluents, heat stabilizers, foaming agents and light stabilizers are added.
The development of the PVC paste resin industry has provided a new type of liquid material that can be turned into polyvinyl chloride products only by heating. This kind of liquid material is convenient to configure, stable performance, easy to control, easy to use, excellent product performance, good chemical stability, has a certain mechanical strength, easy coloring, etc., so it is widely used in the production of artificial leather, vinyl toys, soft trademarks, wallpaper, paints and coatings, foam plastics, etc.
Compared with traditional suspension resins, PVC paste resins have the following advantages:
1) The processing equipment is cheap.
2) The mold is simple and cheap.
3) It can be made into special shapes.
4) Foaming is easy.
5) The number of heating times of the product is less, and it can be produced in small quantities and varieties.

Leaf disease of the fig tree.
The leaves of the fig tree have the shape of an open palm and three to seven leaf serrated edges. This leaf is thick, coarse and softer with hairy sides. It is up to an inch long and wide.
The leaves of the fig tree are susceptible to fungal and viral diseases that lead to early defoliation decline, endangering the fig crop.
The leaf rust fungus cerotelium fici causes leaf rust, usually in mid-to-late summer. Reddish-brown spots appear on diseased leaves'The underside and yellow powdery spores cover these spots. As the disease progresses, the affected leaves turn yellow and brown before dying, falling to the ground.
Since hanging fruit relies on healthy, functional leaves, leaf rust can also interfere with your fig crops by reducing its yield. Fungicide free is approved for use against fig tree leaf rust.
Diagram Mosaic. Diagram mosaic is a disease transmitted by the mite Aceria FICI. It appears as yellow-spotted leaves or completely yellow leaves. As the disease progresses, a rust-colored border surrounds yellow spots.
See Ref. 4) According to Purdue University in the United States, diseased fig trees should be eliminated because there is no ** fig mosaic.
Airborne or web-based epidemics.
The leaves of the antenna or web pages withered and turned yellow or brown as well as soaked in water. The progress of the blight turns the surface of the leaves white. Make the fungal spores Brownian mesh appear underneath it as well. Although the leaves die, they tend to remain on the tree, held by fungal webbing.
Leaf spot disease is caused by two fungi that cause leaf spot in fig leaves, says Purdue: Cylindrocladium flower stick and cercosporus fici. The highest incidence of the disease occurs during the rainy season.
It begins with red-spotted leaves. Its center changes to tan as they grow in size. The fig leaf spot has a brown border surrounded by a yellow ring.
Lesions also appear on the edges of the leaves. Severe infections cause early defoliation decline.

Viscosity: Viscosity is a reaction of the fluidity of the resin. The magnitude of viscosity reflects the resin's ability to wet or impregnate the filler and reinforce the material. The viscosity index of the resin is generally determined at 25. Temperature and the amount of diluent have a great influence on viscosity.

Begonia trees like sunlight, can also tolerate semi-shade, cold-resistant, and have low environmental requirements, and are suitable for growing in loose and fertile, deep soil and well-drained sandy soil. Begonia has strong adaptability, and the cultivation management is relatively extensive. The tree is strong and easy to manage, with a well-developed root system, more fibrous roots, and resistance to cold, drought and waterlogging.
The tree has a long flowering time, and the ripe fruit can give off a fragrance, and it also has medicinal value.
