After welding welding Angle of welding strength is PVC plastic profile Angle under external force ability, and welding technique with PVC itself.
High quality plastic material if welding is not good, Angle of welding strength will be unqualified.
Changshu well below welding of plastic products factory about the PVC plastic profile!
1, welding preparation
before blanking in PVC plastic profile and processing environment should be placed under the same temperature more than 16 h, can help to prevent low temperature of PVC profiles under the condition of the welding heat stress, result in the crack of the PVC profiles.
2, cutting requirements
to ensure the cutting Angle is 90 & deg; And its symmetry. After blanking, cross section to clean.
3, welding technology,
to reasonable welding temperature Settings, general is 240 ℃ - 270℃。 The selection of heating time and heating temperature of harmonious and unified, selection of heat preservation time is also very important.
in order to ensure the strength of welding Angle, in order to improve work efficiency and shorten the cooling time. 80 fan, also in the amount of welding pressure, welding, welding under the condition of constant temperature, winter heating time from 20 s to 15 s, the holding time from 30 s to 15 s, Angle of welding strength fell by nearly 400 n. The reason is that the holding time is short cause solder not fully cooling solidification, welds by quenching falling Angle of welding strength.
4, other
during the welding process, welding cloth dirt to keep clear of in time, if any, timely replacement of damaged welding cloth or charred. Mechanical cleaning groove shoulds not be too deep, to prevent reduce the Angle of welding strength.
