Description

A kind of UPVC Pure water preparation pipe fitting and its manufacturing process

Technical field

The invention belongs to water distribution pipeline material technical fields, and in particular, to a kind of UPVC Pure water preparation pipe fitting and its manufacture Technique.

Background technique

UPVC pipe has temperature-sensitive accurate, fixed using Corvic as carrier when weakening the gravitation of molecular resin interchain When melting, rapid absorbing additives the good characteristics such as effective component, meanwhile, using the famous-brand and high-quality Ca Zn composite type thermostabilization in the world Agent, resin by high temperature and melting during can capture, inhibit, absorb in and hydrogen chloride abjection, with polyene structure into Row double bond addition reaction, active and unstable chlorine atom in displacer molecule.To which effectively scientific control resin is in molten Catalytic degradation and oxygenolysis under state.

UPVC pipe is one kind using polyvinyl chloride (PVC) resin as raw material, not the plastic pipe of plasticizer-containing.With chemical work The development of industry technology can now produce the tubing of nontoxic grade, so it has the performance of general polyvinyl chloride, and increase Excellent properties, specifically it has the advantages that corrosion resistance and flexibility are good, thus especially suitable for water supply network.Due to it It is non-conductive, thus be not easy that electrochemical reaction occurs with acid, alkali, salt, acid, alkali, salt are all difficult to corrode it, so not needing outer anti- Rotten coating and liner.And good this of flexibility overcome over plastic tube brittleness the shortcomings that, surrender can be generated under load action Without rupturing.UPVC pipe also has light-weight.The advantages of convenient transportation.

UPVC pipe heat resistance is poor, and (does not surpass suitable for continuous exhaust temperature in 60 DEG C of environment above tensile strength declines 40 DEG C are crossed, instantaneous exhaust temperature is no more than 80 DEG C of sanitary sewage).Therefore, designing should be such as big away from stove side far from heat source in use In being equal to 400mm, it is more than or equal to 200mm away from hot water pipeline spacing, while hot water pipeline should take Insulation, must not pass through cigarette Road and firewall.

Vybak drainpipe impact strength reduces under low temperature environment.

Specific embodiment

Below by specific embodiment, the present invention is described further, but embodiment is not intended to limit protection of the invention Range.

A kind of UPVC Pure water preparation pipe fitting of the present invention, the pipe fitting include the ingredient of following parts by weight: PVC tree Rouge: 30~40 parts, ACR resin: 20~30 parts, precipitated calcium carbonate: 10~15 parts, haloflex: 5~10 parts, heat stabilizer: 1~5 part, lubricant: 1~5 part, titanium dioxide: 1~5 part, expanding material: 1~5 part, coupling agent: 1~5 part.

Further, the expanding material is vinyl-acrylate copolymer.

Further, the initiator is persulfate or benzoyl peroxide.

Product specification: Φ >=20mm.

A kind of technical parameter of UPVC Pure water preparation pipe fitting provided by the present invention is as shown in table 1.

Table 1

Wherein, test equipment is as shown in table 2.

Table 2

Application method is as follows:

1) it cuts

Tubing can be used the saw that machine power is sawed, wheel-type plastic cement tubing cutter or tooth form are intact and easily cut.To ensure pipe It is cut into vertical smooth, when being cut with saw, has to saw case using angle.The Vietnamese side that pipe is cut, the area for gluing sum are bigger.

2) flash removal

Must with chamfering device or file by inside and outside pipe burr and filings remove it is clean, should in the thin helical teeth of pipe end device so that Nozzle easily enters set section, and reduces the chance for erasing solvent viscose glue on accessory.

3) preparation of accessory

Dust and moisture on accessory are wiped with clean dry cloth, moisture can reduce dry speed, while combine herein Stage, excessive water can weaken bond strength.It is deep that pipe should be able to enter accessory set section 1/2 to 3/4 easily.

4) application of detergent

Glued faying face is both needed to using detergent when pipe is socketed with pipe fitting.Detergent should use about pipe diameter half The dauber or hairbrush of size, unusable rag.Detergent should be coated in outside pipe end and accessory closing in inner face.

5) application of glue

Glue must be coated after pipe surface detergent acts on rather than when moist, engagement surface must be saturated and Softening.

6) it combines

After being painted with glue, pipe fitting should be inserted a tube into immediately and rotates 1/4 circle.At this point, accessory should be properly aligned in case Installation.Pipe must be with pipe fitting socket bottom contact.Combination should maintain appropriate place 10 to 15 seconds to ensure tentatively to combine.Pipe Overflowing with surrounding's glue at pipe fitting junction should be apparent.Excessive portion application rag is wiped.If the glue overflowed around socket Water is discontinuous, indicates that glue is insufficient.Accessory should be abandoned, reconfigure connector.

7) placement and preservation time

The time of placement and preservation is influenced by size of pipe and tubing, temperature, relative humidity and suitable tightness.Environment is drier, Manage smaller, temperature is higher, and tightness is bigger, and the dry time is faster.Under no any engaging force, dispose 1 to 5 minutes.

The installation of product, transport, storage request:

Installation: 1. cuttings；2. burr removing；3. accessory prepares；4. smearing detergent；5. smearing solvent viscose；6. combination.

Transport: when transport is with handling, must not throw fall, be exposed to the sun, staiing, weight and damage.

Storage: tubing is stacked neatly, and bellmouth position should be staggeredly placed, and avoid being squeezed and deformed.Tubing must not be exposed to the sun, away from heat source No less than 1 meter, stacking height must not exceed 2 meters.

It should be noted that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting.Although referring to compared with Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to the technology of invention Scheme is modified or replaced equivalently, and without departing from the range of technical solution of the present invention, should all be covered in power of the invention In sharp claimed range.
