Spectacle frame classification materials and accessories details frame knowledge

Spectacle frame classification of materials and accessories Detailed explanation of frame First, the frame classification 1, divided by the shape: full frame, half frame and frameless three;
2, divided by material: two kinds of metal and non-metal;
Common metal eyeglasses frames include copper-nickel alloys, nickel alloys, high-nickel alloys (also known as "Monel"), stainless steel, titanium, titanium alloys, gold frames, and other metal frames. ;
Non-metallic glasses frames have ------ wood, such as: sandalwood frames, animal bones such as: horns and organic materials such as frames;
Almost all objects that people can touch in daily life can be used as raw materials for frames.
Second, the advantages and disadvantages of various common materials glasses frames:
1, white bronze frame: now used for low-grade products, reading glasses and ordinary sunglasses;
Advantages: good plasticity and low price;
Disadvantages: The product is not high grade and cause more skin allergy symptoms, prone to copper rust, etc.;
2, high-nickel alloy: more used for middle and low-grade teenagers, students frames;
Advantages: light weight, good plasticity, strong color adhesion, many product styles;
Disadvantages: more traditional models, occasionally causing skin allergy symptoms;
3, stainless steel: mostly high-elastic color frame or fine frame; divided into domestic and imported materials;
Advantages: The overall frame has good elasticity, comfortable to wear, and less pressure;
Disadvantages: electroplating layer adhesion is not strong, easy to decolorize; welding point is easy to break;
4, acetate fiber: sub-injection frame (plastic memory) and milling frame (plate);
Advantages of plastic frame: soft texture, comfortable to wear; suitable for children's frame;
Disadvantages: easy to deform, tensile, compressive strength is low, uneven width of the loading slot;
Plate rack advantages: color stability, flexibility, large space, no allergies and other complaints;
Disadvantages: Appearance is cumbersome and varies greatly depending on the technology and design of the factory;
5, titanium frame: see the third paragraph III, the main components of the frame A standard frame with temple (ankle, foot cover), pile head (upper pile, hinge), circle frame ( Ring silk, lining), middle beam, nose pads (leaf stems, pipes, stifle) and other five major components.
Fourth, the specifications and technical requirements of the spectacle frames, frame size 54□18140
Mirror ring size - singular: 33 ~ 59MM; double number: 34 ~ 60MM;
Nose size - singular: 13 ~ 21MM; double number: 14 ~ 22MM;
Lens size - singular: 125 ~ 155MM; double number: 126 ~ 156MM;
2. Technical requirements A. Mechanical properties: Fatigue of the hinge (after opening and closing 2000 times, open 45° without lying down;)
The tensile strength of the joint; the elasticity of the frame; the tensile resistance of the weld.
B. Surface quality: Corrosion resistance of the plating layer; Thickness of the plating layer; Bonding force of the plating layer; Adhesion of the decorative material, etc. (salt spray test).
C. Appearance quality: surface roughness; flaws; solder joints are smooth.
D, assembly accuracy: relative error of left and right circles; coordination of each position; error of standard size;
Body, leg inclination, etc.
Fifth, the frame plating process and the difference 1, "electrophoretic coating" - commonly known as "water plating", that is, through the electrolytic method of the mirror surface color plating process; generally used for ordinary alloy material frames.
Advantages: low cost plating, and rich colors;
Disadvantages: Electroplating layer adhesion is not strong, gold, white, guns generally available for about one year; other colors generally use 3 to 6 months will appear bleaching phenomenon.
2, thick gold plating - divided into "multi-layer plating method" and "multi-layer gold plating" two; because the two kinds of plating process requires the masterbatch is a natural metal color, so the use of such processing frame The color of the product is relatively single, basically consisting of gold and silver. Common frame products include: Japanese Seiko, French Dupont, Milton Pure Titanium and some other high-end frames. It is characterized by thicker plating, generally more than 3.5UM, normal use for about 18 months without fading, no complaints of skin allergies and other complaints.
3, IP vacuum negative ion plating: high temperature to form negative ions on the surface of the frame, free in the vacuum furnace, combined with the pigment particles, through the positive and negative current to guide the adsorption of the surface of the mirror to form a plating layer.
Advantages: environmental protection, strong adhesion of electroplating layer, no discoloration and discoloration in normal use for about 24 months;
Disadvantages: dark color, color plating is not bright.
4, multi-layer coating - divided into two kinds of spray and paint;
A. Spraying process: It is mostly used for the outer coating of students' frame products.
Advantages: rich colors, bright;
Disadvantages: easy discoloration, fade.
B, paint process: used for fashion frames;
Advantages: heavy color, colorful;
Disadvantages: easy to scratch, fade.
Sixth, on the titanium frame 1, titanium frame advantages:
A. Light weight (52% of the same volume alloy frame);
B, wear-resistant, easy to scratch;
C, corrosion resistance, anti-allergic;
D, impact resistance, not easily deformed.
2. Common types of titanium frames: pure titanium, semi-titanium, and titanium alloys;
3, distinguish between pure titanium frames and ordinary frames:
A, weighing method - lack of scale;
B, bending method - suitable for distinguishing between titanium and alloy memory;
C, iron absorption method - can not distinguish between other non-ferrous metal materials;
D, solder joint analysis method - at the junction of the pipe and the stem (a circular welding is not necessarily pure titanium, no ring welding is certainly not pure titanium)
VII. Overview At present, there are a wide variety of titanium frames on the market. Their names vary widely. Prices vary widely. Not only are consumers unknown, but even the salespersons of many optical retailers may not be able to say clearly what is the difference. Through the above description, you can have a general understanding of glasses: the value of a pair of glasses is the production cost (design, selection, processing, plating, packaging, logistics, etc.), retail distribution (inspection, distribution equipment, technology, stocking And a series of issues such as product branding.
