Embodiment 1

[0037] The PPS material is granulated through the special PPS material, and the granulated PPS material is sieved through the sieving mechanism to screen out the PPS material whose internal size is too large.

[0038] Rinse the sieved good PPS pellets twice with clean water, dehydrate the rinsed PPS pellets, send the dehydrated PPS pellets to an oven at 80°C for 5 minutes, and send the dried PPS materials into Heat in an oven at 250°C for 10 minutes.

[0039] The softened PPS material is sent to a furnace at 350°C for melting, and at the same time, it is stirred with a stirring paddle. The PPS material is stirred for 5 minutes after melting, and the melted PPS material is sent to a furnace at 320°C for constant temperature storage.

Embodiment 2

[0041] The PPS material is granulated through the special PPS material, and the granulated PPS material is sieved through the sieving mechanism to screen out the PPS material whose internal size is too large.

[0042] Rinse the sieved good PPS pellets with clean water for 3 times, dehydrate the rinsed PPS pellets, send the dehydrated PPS pellets to an oven at 82°C for 6 minutes, and send the dried PPS materials into Heat in an oven at 255°C for 10 minutes.

[0043] The softened PPS material is sent to a furnace at 360°C for melting, and at the same time, it is stirred with a stirring paddle. The PPS material is stirred for 5min-6min after melting, and the melted PPS material is sent to a furnace at 320°C for constant temperature storage.

Abstract

The invention discloses a hot working treatment technology for PPS modified materials. The hot working treatment technology includes the following steps that A, pelletizing is conducted, wherein PPS materials are pelletized through a pelletizing machine, and PPS materials uniform in size are screened; B, cleaning is conducted, the screened non-defective PPS materials are cleaned with clean water and are dried; C, heating is conducted, the non-defective PPS materials are conveyed to a heating device to be heated so that the PPS materials can be softened; D, melting is conducted, wherein the softened PPS materials are conveyed into a melting furnace to be heated and melted; and E, storing is conducted, wherein the evenly-melted PPS materials are conveyed into a storage groove to be stored. The hot working treatment technology for the PPS modified materials is reasonable, the machined PPS materials are high in out degree, melting of the PPS materials is uniform, and the quality of the PPSmaterials is improved.

Description

technical field [0001] The invention relates to the technical field of preparation of PPS modified materials, in particular to a thermal processing process of PPS modified materials. Background technique [0002] PPS is a thermoplastic engineering plastic containing phenylthio groups in the molecular main chain, which belongs to polyether plastics. [0003] PPS is a thermoplastic engineering plastic containing phenylthio groups in the molecular main chain, which belongs to polyether plastics. It was industrialized in the United States in 1968. The main industrial production methods include solution polymerization and self-condensation polymerization. It can be seen from the molecular structure of PPS that it is a linear or slightly branched polymer composed of benzene rings and sulfur atoms alternately arranged. The main bond has the characteristics of hardness and softness, so PPS can be crystallized and has a high melting point; secondly, because the benzene ring and the...
