Abstract

The invention relates to a manufacturing method for PVC fittings. The manufacturing method comprises the following steps: preparing materials: selecting qualified powder as raw materials and using a stirrer to stir and mix the raw materials; pelletizing: using a pelletizing machine to manufacture mixed powder into particles; injecting: using an injection moulding machine to heat and melt the particles, applying high pressure to the molten particles, injecting the molten particles into a pipe fitting mould, and filling up the pipe fitting mould with the molten particles; closing the mould to maintain pressure: after the molten particles are injected into the pipe fitting mould, cooling the mould to cool and form the PVC fittings; opening the mould to get products: after the PVC fittings arecooled and formed, opening the mould to take out finished product fittings, and performing preliminary checking on the finished product fittings; packaging and warehousing: before packaging and warehousing, performing sampling inspection on the preliminarily checked product fittings in batches one by one. The PVC fittings manufactured by the manufacturing method are high in insulation and flame resistance, are high in impact strength, are high in yield, are good in toughness and intensity, and utilize waste very well.

Description

technical field [0001] The invention relates to the technical field of PVC fittings, in particular to a preparation method of PVC fittings. Background technique [0002] PVC is the abbreviation of English PolyvinylChloride, and its Chinese name is polyvinyl chloride. Using non-crystalline materials as raw materials, it has super high performance in anti-oxidation, anti-strong acid and anti-reduction. PVC also has high strength and excellent stability, and is non-flammable, resistant to corrosion and other phenomena caused by climate change. It is a very good material, because of its high safety, it can be seen everywhere in life. However, the PVC fittings prepared by the current preparation method of PVC fittings have defects such as low thermal deformation temperature, low insulation flame retardancy, low impact strength, low yield, poor toughness and strength, and unused waste products. Contents of the invention [0003] The purpose of the present invention is to impr...
