With the support of the China Printing Association and the Shanghai Printing Association, I was very pleased to participate in the “Quality of Mercury Products†event in Shanghai. I was very pleased to participate in this event. The main product of the company in the Central China region was LQD8E (8D). Equipped with equipment such as horse-riding linkage production line and BBY40/5 wireless glue-binding production line, the company conducted comprehensive, in-depth and meticulous research on quality tracking and usage. The event focused on listening to the user's actual situation and in-depth understanding of the inadequacies of the investigation equipment and some problems that occurred during use. The purpose was to collect the parts that the equipment needed to be improved and improved in the future to meet the needs of users. The need to shorten the distance between manufacturers and users, the distance between domestic products and foreign products, and to keep the products at the domestic advanced level and gradually incorporate international standards. In order to do a good job of this event, six experts with rich practical experience and high professional and technical know-how were hired by the China Association of Printing, the Shanghai Association of Printing, and the Ziguang Company. Ziguang Company has deployed and deployed chief engineers, chief designers, and businesses. The competent and capable professionals, including managers, worked with the expert team to ensure the quality and level of this research activity. The activities were divided into three groups: north, southwest, and central China. They traveled to five provinces and cities including Beijing, Hebei, Guizhou, Yunnan, and Hubei. They learned about and investigated 15 representative printing companies, and traveled thousands of miles. The LQD8E (8D) saddle stitching linkage production line produced by the company in recent years, the BBY40/5 wireless glue binding disc package local machine, and the ZXJD440A paperback wireless glue binding linkage moving line have conducted comprehensive quality tracking investigation. Experts went deep into the first line of production, inspected the operation, production, and use of machines on the site, sampled and inspected the quality of the products produced, and conducted direct talks with managers, technicians, and operators of the use units to directly listen to users. The opinions of the above-mentioned three products were comprehensively, deeply, and detailedly understood; they affirmed the level of equipment and raised some existing problems, which need to be improved in the future to make them more perfect. The company made a practical analysis and evaluation opinion on the product and agreed that the product has a leading position in China and is close to international standards. Shanghai Ziguang Machinery Co., Ltd., formerly known as Shanghai Shuji Machinery Factory, is an early processing plant for printing and binding equipment in China. It is also the main base and leading enterprise for the production of post-press equipment in China. It has provided various books and periodicals printing enterprises in China for many years. There are no fewer than tens of thousands of different types of finishing equipment for printing, which contributes greatly to the gradual realization of the mechanization, automation, and linkage in China's post-press binding production, and creates the “automation and diversification†for binding in India. The favorable conditions won the welcome and favor of the Indian and Indian processing enterprises. In particular, the production of the LQD8E horse-riding linkage production line has reached international standards and is exported to advanced countries in Europe such as Germany, France, Italy and other developed countries. The post-press processing equipment manufactured by Ziguang Company can achieve this level, which is enough to explain the level of its products, the solid technology and the credibility among users. The reason why the purple light became the leading enterprise for the production of binding equipment after the printing and produced equipment that was close to the international level, the one that made me feel the deepest was the spirit of the purple and purple, just as they put forward the slogan: "The first in the light and the fourth in the light." They have a high degree of national integrity and noble style. They have no fear of foreign entry and competition in product manufacturing, can draw on their advanced experience abroad, dare to compete with foreign advanced equipment, and show the noble spirit of the Chinese nation. Ziguang’s leadership, technology, and sales personnel have formed a solid core of unity, and have made every effort to advance to a high level; the spirit of leadership and pioneering spirit, the excellence of technical personnel, perseverance, and the hard-working and hard-working sales staff. I am deeply touched by the touching stories of user service piles... From the purple spirit and purple light products, I saw the hope and future prospects for the development of China's post-press equipment. In particular, the technicians who have engaged me in a post-press binding business for more than 50 years are full of joy and relief. For a long time, there has been little attention paid to post-press binding, and it has become painful to see some companies spending expensive money to purchase foreign equipment. Some foreign equipment does have high manufacturing levels (including raw materials), good wear resistance, and long service life. However, some of China’s equipment, whether it is materials (main steel products) or technology, have a certain gap compared with the advanced level in foreign countries, and therefore their hearts are anxious. Who does not want their country’s products to dominate the world? Today, Ziguang has given us new hopes, because through this “Million Miles†campaign, I saw the purple light and the purple light spirit. I saw the purple light products. I believe that in the near future (as soon as possible), China will Post-printing equipment on the international advanced (8E has entered). Although I have two 60, I am still looking forward to the arrival of this moment as soon as possible. Violet is hard-won today. To maintain it, we need to spend more effort, work hard, and advance. Otherwise, we will overturn the boat in the midst of a market economy. This trip to Wanli is a new starting point for Ziguang to enter a new century. The past has already passed. Everything starts from scratch. I hope that Ziguang will enter the WTO and be invincible forever, and carry forward!
Metal Zipper
Metal Zipper
Metal zipper zipper belongs to one of the microphones refers zipper teeth made of copper, aluminum or copper-nickel alloy material produced zipper, resin zipper and Nylon Zipper compared in terms of, more durable, and more for jeans, jackets and backpacks.
Features: Rugged, higher cost
Divided according to the size: # 3, # 4, # 5, # 7, # 8 and so on, depending on the size microphone size zipper teeth change. Because it is often used in the jeans, jackets and backpacks, so its dimensions are larger zipper.
classification:
1. TYPE: closed zipper,
Opening zipper (detachable),
Double closed end zipper (X- zipper with double slider zipper with two opposite or O- double slider two opposite), double open end zipper (Inverse open detachable)
2. Mi tooth Material: Existing material type of aluminum, brass, copper-nickel alloy, zinc alloy. Color metal microphone teeth often as needed electroplated, such as aluminum plated microphone yellow teeth, tooth-plated brass microphone white, black nickel, bronze, red bronze, gold and other colors.
Metal zipper Composition:
And other similar zippers, metal zippers composition is formed by a cloth belt, microphone teeth, slider, limit codes.
Tape: Material generally fiber belt, cotton or polyester fibers with a belt, can choose different materials depending on the application.
Mi teeth: the market for the production of metal zipper and more aluminum, brass, copper-nickel alloy, zinc alloy and other materials made of, since the color on the metal zipper teeth are plated microphone up, if improperly stored, the teeth will turn black microphone clothing and would cause pollution. For microphone tooth copper alloy is prone to oxidation, so when you save to ensure a certain degree of ventilation, do not sealed, do not save in the moisture-laden environment, if necessary, have to use the moisture-proof paper or desiccant.
Slider: metal slider respectively bronze color, red bronze plating, white, yellow-plated, black nickel, black nickel, matte silver, under normal circumstances, the color of the metal slider requires a microphone with a metal zipper teeth the same color. According to regulations, common slider parameters are:
3 # metal slider opening height of 2.1-2.2mm, mouth wide as 4.55-4.65
5 # metal slider opening height of 2.7-2.8mm, mouth wide 6.0-6.05
Limit code: divided into upper stop (front yard) and bottom dead center (post code). The main role is to prevent the upper and lower retaining slider from microphone teeth.
Note:
In the garment washing or processing time, pay attention to:
A wool knitwear after being ironed, to ensure adequate cooling can after zipper packaging, otherwise,
After the metal zipper will react with steam generating, easy to change color. Second, in the clothing trade processing, it tends to remain certain chemical reagents, then it is easy to react and metal zippers. Therefore, prior to assembly of metal zippers, leather has been the need to ensure adequate for cleaning and neutralization.
remind
Since there are different zip adaptability in different environments, so in the selection and purchase of the zipper when you choose must inform the manufacturer of the zipper on the application in which products, and manufacturers have to inform you of the fastener component requirements, such as You can be a pin detection and so on. Further, generally prohibit the use of azo dyes in the composition, as the dyed fastener after contact with body induce certain diseases.
Maintenance tips:
First, the science of using a metal zipper:
1, when the metal zipper pull, it must be close to both sides of the tooth, must be aligned to the top, then head down the track holds metal zipper pull gently, not too much force to pull.

2, when moving the metal zipper should be careful not to hem skirts or other debris caught in the metal zipper in order to avoid "crooked teeth", "belly", "off the teeth" and so on.
3, if the metal zipper astringent, not easy to pull, do not dead lift, put some wax or soap on top of a metal zipper, you can pull.
4, if the metal zipper teeth unilateral differences rope, wear loose hair, available in popular tiger clamp closed end of the metal zipper lateral gently clip, metal zipper immediately changed for the better, unilateral teeth together tight, no broken loose.
Second, to prevent metal zipper moisture, oxidation, rust and discoloration.
1, to avoid contact with the moist environment: because the metal zipper metal oxide due to the dip caused by tooth portion has a black phenomenon.
2, avoid contact with rubber band: Because rubber band itself contains sulfides, when bundled with rubber band metal zipper, metal chain teeth will have vulcanized phenomenon (black).
3, should be cleaned and dried after washing with water: because the fabric dye or residual chemicals and metal parts redox reaction, metal parts may cause discoloration.
Cause of Color Changes
a, copper alloy (copper-nickel alloy, copper, brass) made of metal zipper discoloration of reasons:
When used in the metal or hair products, metal zippers metal due to oxidation caused most of the teeth have a black phenomenon. This is because when the bleach manufacturing process of cooked skin leather woolen products agents on the process and remains in the product, the product gas can cause discoloration of the metal zipper.
Examples of chemical reactions: oxidizing bleach (H2O2) → black (CuO) or red (CuO2);
b, rubber bands bundle of metal zipper color reasons:
Rubber band itself contains sulfides, when the rubber band bundle metal zipper, metal chain teeth will have vulcanized phenomenon (black).
Chemical Reaction Example: excess gas sulfides or HS2 conditions → black [CuS]
c, contact with an acid or chromium compound causes discoloration.
Chemical Reaction Example: acidic compound and chromium compound [Cr2O3] → Black [CuO, red [CuO2] or blue [CuSO4].
