Description
Technical field
The present invention relates to a kind of manufacturing process for plastic product, and in particular to a kind of new heat shrinking sleeve Making programme.
Background technology
Middle and later periods nineties oil and gas industry starts using thermal contraction product, and the fields such as city gas pipeline, water supply pipe were extended to later.At present the equipment of production shrink belt is technically relatively backward, have impact on the production of thermal contraction product, seriously constrains the development of industry.Prior art forms stretching, the gluing after x ray irradiation x when heat shrinking sleeve is produced during by production PE base materials, become thermal contraction product, but due to automatization level it is low, it is impossible to accurately control shrinkage factor is formed, about within 20-30%, amount of contraction is unstable, cause engineering construction slow, take, power consumption, coated reliability is poor, affects construction quality.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, a kind of new heat shrinking sleeve Making programme is proposed, the flow process solves the technical problem that irradiation rear substrate redraws, can One-step production thermal contraction product, continuous operations are formed, the shrinkage factor of thermal contraction product is substantially increased.
The technical scheme is that：A kind of new heat shrinking sleeve Making programme, including following making step：
1）Get the raw materials ready
Plastic matrix and melten gel are taken out, the semifinished material for being complex as substrate layer and melt layer is produced, according to diametric requirements different in width, the shrink belt finished product of different length are prepared.
2）Pretreatment
To pyrocondensation base material otch, the shrink belt for being complex as bilayer is made the stripping of substrate layer and melt layer.
3）Base material/substrate layer heat seal
Base material/base material two ends are carried out into electric heating heat seal on equipment
4）Base material/substrate layer cooling
Base material position after heat seal, carries out laminated type cooling so as to reach the temperature requirement of suitable subsequent processing.
5）Base material/melt layer heat seal
Base material after cooling and ground floor colloidal sol are carried out into wind-heat heat seal.
6）Melten gel/melt layer heat seal
Ground floor colloidal sol and second layer colloidal sol are carried out into wind-heat heat seal.
7）Welding side is arranged
Repair the part overlap because occurring after heat seal, it is ensured that product is attractive in appearance.
In the stripping process of pre-treatment step, to pyrocondensation base material otch after, make K cryogenic treatment, temperature, then using 8-10kg pulling force, glue is separated with base material at subzero 10 ° to subzero 15 °；
During base material and base material heat seal, base material temperature is 1.5-1.9MPa using pressure in the state of 270 ° of 240-, stops the stable 160-180 seconds；
In base material pressing formula cooling procedure, base material is applied 5 to 0 ° under zero temperature, to base material rapid cooling, pressure is 1.0-1.5MPa, second stabilization time 140-160；
During base material and PUR heat seal, PUR is pasted with base material, and temperature range is 220-240 °, and pressure is 0.1-0.5MPa, second time 100-130；
During PUR and PUR heat seal, temperature 200-230 °, pressure 0.1-0.4MPa, second time 90-120.
The present invention has the advantages that：
The present invention efficiently solves the problems, such as that the shrinkage factor that shrink belt is carried in work progress is low, using the step, realizes base material stretching, gluing position One-step production, make production process simplification, unification, production efficiency is significantly improved, reliable product quality, substantially increases the construction quality in construction.
