CN205136847U - Enhancement mode polypropylene random tubular product - Google Patents

Abstract

The utility model discloses an enhancement mode polypropylene random tubular product, it includes the body, the body is bilayer structure, and its inlayer body is the PP -R layer, and outer body is the enhancement layer. The product utilizes thermal composite process outside of tubes complex in PP -R to become the one deck enhancement layer, and this enhancement layer is to the whole humidification that plays of pipe -line system for tubular product appears reduced by the probability of external force fracture around the installation by a wide margin. Can prevent in addition unfavorable environmental factor in construction site operation and the transportation transport to the invisible injury that tubular product led to the fact, in use leaks because of throwing, fall, rub afterwards to prevent tubular product.

Description

A kind of enhancement mode three type polypropylene pipe

Technical field

The polypropylene pipe technical field that the utility model relates to, specifically a kind of enhancement mode three type polypropylene pipe, particularly its mechanical connecting structure.

Background technique

Although hot and cold water plastic tube has high temperature resistant, high pressure resistant, corrosion-resistant, convenient transportation, is easy to the advantages such as installation, also Shortcomings.For III type polypropylene, by propylene monomer and a small amount of vinyl monomer, random copolymerization under heating, pressurization and catalyst action obtains for it.Vinyl monomer is distributed in propylene long-chain randomly, and wherein vinyl monomer general control is at 3%-5%.The polymerization methods of ethylene contents and ethene and propylene determines the feature that it has cold shortness.When temperature is lower, in particularly winter construction process, tubing at low temperatures pliability reduces, and rigidity reinforced, shows as embrittlement.When tubing is subject to impact or the weight of external force, there will be straight line cracking phenomena, and cracking is extended to outer tube by interior pipe.After the cracking that the active force that tubing is subject to a point causes, this cracking can increase fast along the axial direction of tubing.Tubing is because external force is caused injury in transport, building site and installation process in addition, in use can occur fragility and toughness (during conveying hot water) booster.

Although country has made clear and definite requirement for this problem in job specfication, namely during winter construction, the feature of the low temperature brittleness of building water supply polypropylene (PP-R) pipeline should be noted, and formulate corresponding arrangement and method for construction.But the pipe leakage problem caused due to brittle cracking still constantly occurs, and causes damage and perplex to user.

Summary of the invention

The purpose of this utility model is to provide a kind of enhancement mode three type polypropylene pipe.Product makes tubing wall be followed successively by enhancement layer and PP-R layer from outside to inside by complex method.By the effect of enhancement layer, tubing external shock resistance ability is greatly improved, and significantly strengthens tubing bulk strength.Overcome the shortcoming and defect existed in prior art.

To achieve these goals, the technical solution of the utility model is: a kind of enhancement mode three type polypropylene pipe, it comprises body, it is characterized in that: described body is double layer construction, and its internal layer body is PP-R layer, and outer body is enhancement layer.

The utility model discloses a kind of enhancement mode three type polypropylene pipe, product utilization hot composition process is compounded to form one deck enhancement layer outside managing in PP-R, this enhancement layer plays humidification to pipe-line system entirety, and tubing is occurred in a pre-installation afterwards, and the probability by external force cracking significantly reduces.The covert harm that can prevent the adverse environmental factors in job site operation and transport carrying from causing tubing in addition, prevents tubing from use leaking after throwing, fall, rubbing.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Wherein:

1. body;

2.PP-R layer;

3. enhancement layer.

Embodiment

With reference to the accompanying drawings, the utility model is described further.

The utility model is a kind of enhancement mode three type polypropylene pipe, and as shown in fig. 1, it mainly comprises body 1, and it is different from prior art and is: described body 1 is double layer construction, and its internal layer body is PP-R layer 2, and outer body is enhancement layer 3.The inwall place of above-mentioned PP-R layer 2 also can be covered with at least one deck nano-silver ionic layer.

In the specific implementation, Thickness Ratio 3:1 between described PP-R layer 2 and enhancement layer 3, this thickness ratio can guarantee that body there will not be the phenomenon of surperficial body jackknifing when bending, simultaneously, body after bending not easily restores, the sizing after utilizing internal and external layer body properties of materials to coordinate thickness ratio to realize bending.

More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
