Description

A kind of reinforced polypropylene Dual-wall winding flat tube

Technical field

The utility model relates to polypropylene technology field, specially a kind of reinforced polypropylene Dual-wall winding flat tube.

Background technique

Polypropylene is a kind of thermoplastic resin as prepared by propylene polymerization.It is divided into isotactic poly- third by methyl arrangement position Alkene, random polypropylene and three kinds of syndiotactic polypropylene, polyacrylic crystallinity is high, compound with regular structure, thus has excellent mechanical property Energy.The absolute value of Mechanical Properties of PP is higher than polyethylene, but still falls within relatively low kind, tensile strength in a plastic material It only can reach 30 or slightly higher level.The biggish polypropylene of isotactic index tensile strength with higher, but with isotactic index It improves, the impact strength of material declined, but after dropping to a certain numerical value.Temperature and loading speed are to polyacrylic toughness shadow Sound is very big.When temperature is higher than glass transition temperature, impact failure is in ductile rupture, is in brittle fracture lower than glass transition temperature, and Impact value sharp fall.Loading speed is improved, the temperature that ductile rupture can be made to change to brittle fracture rises.Polypropylene With excellent flexural fatigue resistance, product at normal temperature bent 106 times without damage.But under room temperature and low temperature, by Molecular structure regularity in itself is high, so impact strength is poor.Polypropylene performance most outstanding is exactly counter-bending fatigue Property, it is commonly called as polypropylene (PP).Polypropylene has good heat resistance, and product can carry out disinfection sterilizing in 100 DEG C of temperatures above, not by Under conditions of external force, 150 DEG C also indeformable.Brittle temperature is -35 DEG C, embrittlement can occur lower than -35 DEG C, cold resistance is not as good as poly- Ethylene.There is a 18qC, 0qC, 5 DEG C etc. for the reported values of polypropylene glass temperature, this is also due to people using different examinations The ratio of sample, crystal phase and amorphous phase contained therein is different, makes in strand caused by pars amorpha chain length difference.

Existing polypropylene is a kind of thermoplastic resin, also known as polypropylene (PP), and the heat resistance that compares in same material is higher, Easy to break but since molecular structure regularity itself is excessively high, in investment sewage treatment works, use is easy warm too long Its service life of the Different Effects of degree.
