Description
Technical field
The present invention relates to tubing mould, particularly relate to a kind of mould manufacturing composite soft tube and the system of composite soft tube
Make method.
Background technology
Along with improving constantly of people's living standard, health and safety is the two principal themes that modern payes attention to the most,
The safety of drinking water and the water quality of domestic water and water pipe particularly becomes focus of concern.Drinking water is
Finger can directly feed, without process, the water that human body is quoted, including the drinking-water required for human body every day and
Domestic water, wherein, the quality of drinking water is not only relevant with Drinking water quality itself, also with the conveying of drinking water
Pipeline is relevant.From the point of view of quality of drinking water ensures, Running-water Company produces standardized Drinking Water
Being transported to huge numbers of families by water supply line, people usually touch or can the most feed pipes of self-changeable
Road is exactly the flexible pipe carrying drinking water, if described flexible pipe fails safety standards, it will directly influence people
The health of body.
Owing to people are to improving constantly that the wholesomeness of drinking water requires, it is meant that to flexible pipe safe and sanitary
The raising required.The rubber commonly used till now from the metal tube in past or plastic flexible pipe, drinking water flexible pipe towards
Direction safe, light, corrosion-resistant is developed.Due to rubber or the flexibility of plastic flexible pipe, so that described
Flexible pipe becomes indispensable product at home finishing, daily life drainage facility are installed, it is adaptable to soft or
The position of flexible connection, is used for transmitting kitchen, drinking equipment, filter plant, bathroom than flexible pipe as will be described
Flexibly connecting in facility.Wherein, the drinking water either eaten for people is still straight for people's health
The drinking water of contact, makes safety and sanitation and people's health of described flexible pipe by the transmission of described flexible pipe
Healthy closely related company.
Existing flexible pipe wide variety, common rubber or plastic flexible pipe are mostly single layer structure, common are
Ethylene propylene diene rubber (EPDM), TPV (TPV), thermoplastic elastomer (TPE) (TPE) or
The polyethylene (PE) of monolayer, crosslinked polyethylene (PEX), polrvinyl chloride (PVC), PVC-U (UPVC)
Deng, when being used alone certain material, it is understood that there may be the flexible pipe that above-mentioned material prepares there may be flexible not enough,
On the high side or do not meet safe and sanitary need situation.It is as the most bad in the freeze proof of UPVC pipe and temperature capacity,
The flexible deficiency of pvc pipe, in most cases, is more suitable for wireway and blow-off line, even if by adding
Add agent phthalein and it is soft that PVC is become, but on human body kidney, liver impact very greatly, be not suitable for transmission and drink
Water.If being used alone PEX mono-layer tube, the rigidity of body is too high, it is impossible to meet in small space flexible
The requirement connected；If being used alone PE mono-layer tube, hardness therein is excessive, during water delivery, and pipeline
It is not easy bending, it is difficult to install at small space；If using single TPV (three is the most flat) material, price
Too high cause cost increase, cause purchase volume less, and cheap other kinds of TPV material is not
The needs of safe and sanitary can be met.Conventional EPDM pipe has abnormal flavour due to itself, during long-term use,
Directly contact with water and may result in harmful substance and be dissolved in wherein, human body is damaged, although price is relatively
Low, but the needs of safe and sanitary can not be met.
