What makes uneven wear outsoles

  •    Personal reasons: Firstly, pigeon toe or other bad habit to walk, the shoes will make contact with the ground, receiving points to a location not balanced result in increased wear, shoes directly affect the overall appearance and longevity.
  •     Solution: Firstly,you have to walk to develop a good habit to overcome their past bad way to walk, try to touch the ground with the heel to the sole way to walk the order, can make shoes by the force balance can greatly reduce surface wear shoes , then it will develop a good habit to walk, while maintaining a good posture why not do it.
  •     Other solutions: 1. If you really can not change their walking habit, it can be sticky soles way around, it is best bought new shoes directly to find a shoe repair master all marked soles of the sole, so when you're not afraid to walk the ground, soles worn out it does not matter, the bottom of the shoes themselves are not bad you can continue changing his palm (this method shoes, casual shoes apply. athletic shoes is not applicable).
    2. Better to have two to three pairs of shoes worn backwards, shoes also need to rest. If you often walk, smooth pavement should choose to walk, easy to wear shoes, if you at the mall or subway station in the marble floor to walk, the sole is not easy to wear. After choosing your shoes when not only consider the shape, it should be more attention to the soles of the material, try to choose a point of moderate hardness thick soles soles.

What outsoles should be wored when driving

slippery brakes when wearing high heels

  •      Experimental procedure: Reporters found driving car driving, the heel is easy to get stuck throttle, brake pedal, and sometimes by feet hobbled, calf feels tight and there is a sense of soreness. In addition, because of the small size heel shoes, stepping side to side foot brake pedal, easy to slip, the brake force is difficult to control. Reporters found that the emergency brake, the heel is also easily stuck in the next step on the brake pedal is not in the end, resulting in brake not working.
    Experiment Conclusion: wear high heels to drive, control the brake without the focal point, the higher the heel, the less force on the brakes, emergency situation the driver will feel powerless, brakes are not in the end.
  •      Usually walk heel wedges comfortable than a single, but into the cab, because the front and rear with height, back and forth between the brake and throttle move inconvenient, can not grasp the intensity. Men's snow boots also exist such problems, reporters measuring one pair of men's snow boots 42 yards found the forefoot width is 12cm, and the small car brake pedal with the right spacing of about 13cm around the body, it is easy to get stuck.
    Many female students winter school car, will choose the warm and good snow boots or high boots, she always drove repeatedly stressed the importance of wearing flat shoes. Too hard or too thick soles of shoes to wear while driving is not recommended because of the lack of foot feeling when driving, the driver can not correctly determine the degree of control of the car.
  •         If it is from the perspective of warmth, it is recommended to wear snow boots, platform shoes women driving in the car to prepare a pair of shoes fit, so both warm and guarantee safe driving. In addition, the driver should pay attention to their soles, soles once there is snow or ice to be removed immediately, otherwise the brakes, easy to mistakenly stepped on the accelerator, the consequences could be disastrous.

Sole is too hard or too thick to wear is not recommended to drive

There is snow or ice on the sole to immediately clear

Flat shoes with thin outsole-girls' favorates

Doll Shoes with thin outsole

  •         Not just high heels, many seemingly safe shoes also hurt the foot, such as popular among female office worker  (flat shoes).
         Observed female office workers, you will find people who wear high heels now less than expected, replaced by sections like Bodi like ballet shoes flat shoes. But flat shoes are not selected will hurt feet.
         flat shoes thin soles main problem is there is no "in the end", so less shock-absorbing shoes should function sometimes equivalent to walking barefoot on the ground. Many women take a long time to begin heel pain; Some people walking posture problems, to sole, also appear forefoot pain, plantar fasciitis will produce long-term. Diagnosis must see patients walking posture, will know where the problem, not just a temporary solution.
         In addition, many cheap shoes material is very hard, not long started wearing frayed heel, instep, etc., every step will tear it. Some women will carefully observe paste a heel OK stretched, will be the last blisters or abnormal proliferation. This is because the flat shoes shallow mouth, no instep strap to help fixed foot, heel kept rubbing up and down, more prone to this condition.
         In addition to the heel, the foot of each person is different, some people compare the bones protruding, narrow lasts doll wear shoes or high heels, toe joints easy to grind dolphin calluses.
         Some people rely on arch supports or insoles to relieve foot pain. But with little effect, because the coating is not high enough heel so thick insoles, heel but easy to run out; Some hurts because of foot structure, especially the front foot rotation, load-bearing arch collapse caused, if coupled with adequate bow cushions, so hold up the arch, but pull into the plantar fascia, the pain worse.
         Therefore, select "flat shoes", the end can not be too thin, choose a low heel shoes with thick or better; vamps can also try to find the shoes forefoot cladding; insoles not mess plus-gap first for double shoes, if persistent pain, go first to the doctor to understand the main cause of his sore foot, look at doctor did not recommend to buy insoles. Experts suggest that the best Bodi flat shoes slippers to wear when the room is like, if go out for a long time, it is best discarded flat shoes.

Recipe of Vulcanized shoes outsoles

Written by

Recipe of Vulcanized shoes outsoles

  •      Vulcanized shoes outsoles , molded bottom secondary sulfide , a sulfide and the secondary vulcanization time less than 48 hours apart , the second with autoclave curing .
     First by high-end shoe concept to analyze, as a rubber outsole material properties are often pursued is abrasion resistance , slip resistance, with some tear strength, good adhesion properties , appropriate anti-aging properties and a certain degree of flexibility , cattle Zhu bottom need some transparency. ^
           In terms of this concept to analyze this recipe ; first match is the main glue on the surface appears to be very unreasonable , natural rubber and styrene-butadiene rubber and rubber with abrasion resistance in general is impossible to achieve the best wear resistance, this is far from the two rubber vulcanization rate of vulcanization take longer curing time is often a persulfate natural rubber , styrene-butadiene rubber or less sulfur , styrene-butadiene rubber elasticity difference and use too much flexibility will be even worse . In order to achieve a total of vulcanization accelerators require a lot of increase in the amount of spray can cause severe frost hazard. From the curing temperature , there is also a great time to look unreasonable , look natural rubber from the temperature most suitable temperature is 143 degrees but not more than 150 degrees , otherwise it will return to the original , depolymerization , resulting in poor physical properties .
           From the curing time of vulcanization in order to achieve in terms of only 150 seconds is too short for the SBR , unless a substantial increase in accelerator, accelerator and will increase the risk of spray cream . And the cost of natural rubber market is also high, too high dosage is suspected . However, high-end formulations are based on butadiene -based rubber, with natural , SBR to improve process performance . Use butadiene rubber has superior abrasion resistance and flexibility as the main glue , the use of natural rubber to improve the tension , slip resistance and adhesion strength with SBR to improve overall performance and anti-aging properties .
       Curing system is a sulfur cure system , accelerator with a thiazole with thiurams , which is commonly used vulcanization systems , sulfur amount of relatively normal, but to promote the dosage is too high , especially accelerator M, DM concentration far exceeds the solubility of the rubber , the risk of spray cream is inevitable , stearic acid 3 parts high point , but also the risk of discharge , the amount of 6 parts of zinc carbonate is no problem . But under normal circumstances can be used 4.5 parts .
     Reinforcing system usage reaches 75 parts silica dosage obviously excessive normal circumstances if it is not the pursuit of high hardness , the amount of more than 60 copies of properties decreased. 7.5 parts of diethylene glycol is used for improving the affinity of the silica with the rubber , and is a basic, acidic activator accelerator can be appropriately reduce the amount of accelerator help tune fast curing speed . 6 copies of the normal dosage is sufficient
          Softening oil used in 45 copies, is basically filled with oil , mainly used to reduce the physical properties is definitely declining . Not conducive rubber aging, after vulcanization its softening oil will continue to slowly migrate to the surface . After a long Ding enlarged bottom hardness will be significantly increased. Because the amount of oil is too high , breaking the major recipe with the equilibrium . Because the amount of natural rubber is too high, sticky roller , a small amount of wax is mainly used to improve anti-fogging process performance , dispersants suitable mixing kneader secret process , to help with the dispersion . Antioxidant no increase is primarily based on requirements of anti-aging products , as well as formulations with status quo , it is quite Annexed practical.
      This is based on rubber formulations , and high-end shoe concept commentaries recipe , apparently with the system of the five formulations is uneven, there is a serious flaw.
        However, according to the actual situation of the factory on the analysis of this recipe is another case . This product is a cloth shoes outsole, the footwear is the low-end products , the first test the filter is allowed in the case of physical properties , reduce formulation costs.

How to make EVA outsoles

  • EVA soles making recipe

    • Common market injection foam molding EVA Material pellets are generally used EVA, modifiers (such as POE, PE, BR and other chemicals) and other additives blending extrusion granulation made.
    •        The past 10 years, the domestic producers in order to broaden or maintain their market area, focusing on lower material costs, to take to add renewable EVA, or other inexpensive elastomeric material, or increase the inorganic materials added amount, or the use of EVA foam shoe recycling materials and other means to create low-cost, low-end shoes, the use of these tools produce EVA foam sole difference there is generally resilient, easy deformation, easy to brittle, prone to cracks and other defects .
    •         I use with low cost, low density, good mechanical properties of the advantages of plant fibers and EVA resin can be prepared by blending modification of plant fiber high foaming / EVA composite shoe pellets. As the cellulose macromolecules wood repeating units in each base ring containing three hydroxyl groups, these hydroxyl groups to form intramolecular hydrogen bonds or intermolecular hydrogen bonds, the fiber having water absorption, moisture absorption rate of 8% to 12% [3], while the majority of non-polar thermoplastic.

Transparent rubber outsole's details

  •         Transparent rubber is divided into two kinds, one is translucent rubber, vulgar city tendon at the end. Another is pure transparent rubber, commonly known as glass, plastic. Today, we mainly talk translucent rubber formulations and processes.
  •        The country's factories are producing tendon at the end, but can be really strict accordance with the process to operate, can reach the theoretical value formula set a handful. One reason is that in order to save costs, the second is the formal process in the end do not know how to do that. Most of the others are copied, as long as the color can be close to, can do just fine translucent.
  •        Today I'm talking about is a way to reach the theoretical formula set recipe and process, as a basic framework that can produce around 2000, reached the international advanced level on the physical properties of the standard. You can also reach making products such as NIKE and ADI standards. Why do I say not meet latest international level, is due to the material and the limitations of our philosophy.

Outsoles Making Recipes You should know

  •        In the current commercially available on the market a wide range of sole material, the pattern varies. Sole or shoe manufacturer must determine what their products should meet the performance, in line with what criteria, and must choose to create Material: Rubber (RU), thermoplastic rubber (TR), polyurethane (PU) or thermoplastic polyurethane (TPU). Shoe uppers made ​​as an integral part of and must work closely together with the sole material, so manufacturers respond upper materials make the right choice. Well as the design and performance, all these parts must be properly selected in order to ensure good quality of the final product.
  •         Of course, shoes and shoes can not be generalized to different requirements of shoes, especially on the soles of the requirements, but also not the same. Requirements for the sole
    Relates to an improved mixing nano powders of natural rubber, abrasion resistance barite methods, especially by mixing the organic surface treatment of nano-modified natural rubber, barite powder to improve the wear resistance. Of the present invention is: in the rubber mixing process of adding the organic surface treatment agent after treated nano-modified natural barite powder, the protective rubber formulations unchanged original production and production processes based on the same, addition of 1 ~ 5% of the composite powders.
