Description

A kind of PSF alloy
Technical field
The application belongs to plastic alloy material field, particularly relates to a kind of PSF alloy。
Background technology
PSF is the abbreviation of pointspreadfunction, i.e. point spread function, weighs the resolution of the image after reconstruction by this index。In linear system, for any imageable target I1 and its correspondence can be expressed as I2=I1*h, h as I2 be system function。This convolution coefficient h is exactly PSF, because when I1 is impulse function, and I2=h。The quality of I2 depends on h。When h more deviates impulse function, I2 is more fuzzy, and its fog-level can be weighed with the width of h, and h is more wide, and I2 is more fuzzy。Spatial resolution is defined as, it is possible to distinguish the minimum interval of two differences。The width of PSF determines the spatial resolution rebuilding image。For the image from Fourier sampling reconstruction, its resolution depends on the resolution of Fourier, no matter after reconstruction sample in image area which kind of difference or zero padding scheme, all can not improve the spatial resolution of image。
Acrylonitrile-butadiene-styrene copolymer English name: AcrylonitrilebutadieneStyrenecopolymers, is called for short ABS。ABS is a kind of intensity height, good toughness, thermoplastics type's Polymer Materials ' Structure easily processed into type。ABS resin is acrylonitrile, 1,3-butadiene, cinnamic terpolymer。Can acting normally under the environment of-25 DEG C～60 DEG C, and have good mouldability, the product surface processed is bright and clean, it is easy to dyeing and plating。And can compounding with various kinds of resin become blend。Primarily now for alloy, plastics, and the ABS trade mark。
Industrial PSF molecular weight is typically in 50,000～110,000 scopes, has bigger polydispersity, the reduction of molecular weight with polymerisation temperature and increase；Without definite melting point, 80～85 DEG C start softening, and 130 DEG C become viscoelastic state, and 160～180 DEG C start to be changed into viscous state；There are good mechanical performance, about tensile strength 60MPa, impact strength 5～10kJ/m2；There are the dielectric properties of excellence。
Polyethylene terephthalate chemical formula is-OCH2-CH2OCOC6H4CO-English name: polyethyleneterephthalate, it is called for short PET, it is generally high polymer, PETP is the oligomer (BHET) being generated ethylene glycol terephthalate by p-phthalic acid and ethylene glycol generation esterification, and BHET takes off ethylene glycol gained further under partial vacuum。The PET being not added with additive in polymerization process is transparent glossiness；Becoming milky after drying crystalline, degree of crystallinity is generally 30-40%, and surface smooths glossy。Uncrystallized PET goods use temperature should lower than 50 DEG C；Goods, fiber and fabric after crystallization sizing have excellent physical and mechanical properties in wider temperature range, life-time service temperature is up to 120 DEG C, electrical insulating property is excellent, even under high-temperature high-frequency, its electrical property is still better, but corona resistance is poor, creep resistance, fatigue durability, rub resistance, dimensional stability are all fine。
Polypropylene English name: Polypropylene, is called for short: PP, is commonly called as: polypropylene (PP)。Polypropylene is the representative of poly alpha olefin, a kind of thermoplastic resin prepared by propylene polymerization, and monomer whose is propylene CH2=CH-CH3。Difference according to initiator and polymerization technique, polypropylene can be divided into isotactic polypropylene and random polypropylene and three kinds of configurations of syndiotactic polypropylene。Isotactic polypropylene is easily formed crystalline state, and degree of crystallinity is up to more than 95%, and molecular weight, between 8-15 ten thousand, gives its good heat resistanceheat resistant and solvent resistance；Random polypropylene is at room temperature a kind of adhesive White waxy thing amorphous, micro-, and molecular weight is low, at 3000-10000, and the irregular shortage cohesiveness of structure, apply less。
