Using the information printing silicone rubber

Firstly,clean the mold with detergent, and dry out the mold by an item of cloth or even an air gun after which coat the mold which has a layer of release agent. 2. The normal proportion relating to the pad printing silicon as well as the silicone oil depends on the requirements the customers can use. If pattern with big place to be printed, a soft silicon pad is needed and the volume of silicone oil is increased. Contrarily, if your silicon pad with higher hardness is required, the silicone oil should be added less or otherwise . The hardness of general pad printing silicone rubber is approximate of 15%~-25% if an excessive amount of silicone oil is added, the silicon pad is really soft that the printing times is bound, the molecular weight of the silicon will be damaged by the silicone oil regardless how superior quality the silicon is, thereby causing abrasion intolerance, solvent intolerance and ageing. 3.General mixing proportion can be as follows: add 30g silicone oil into 100g silicon using the hardness from the silicon pad being 20A%uFFFD, that's well suited for the material printing for alloy car and items with small patterns and speak to areas. If a big pressure contact surface or possibly a soft silicon pad is needed, the mixing proportion between your silicon as well as the silicone oil may be 100:30-100:50. But please be aware that the harder quantity of silicone oil added, the softer the silicon pad, that may reduce points during the pad printing, abrasion resistance and solvent resistance. In addition, the days of pad printing will likely be correspondingly reduced that may cause increased cost and material waste. 4. The amount of the curing agent and also the chemical reaction with the silicon will be as follows: mix 100g silicon and 50g silicone oil sufficiently and evenly, you can add the curing agent which is 2%-3% from the total weight with the silicon along with the silicone oil, mixing for 2-3 minutes, after which deair to take out the air bubbles . The time of deairring generally doesn't exceed 10 mins. If the deairing time is simply too long,it can fast curing from the silicon and impact the quality of silicon.

Installation Method of Clear silicone sealant

Clear silicone sealant has been used for several years to seal windows and doors after installation. It is a good product to work with when waterproofing a task. It isn't tough to use, and, by using quick and easy steps, you will probably find that you have become a pro. Remember, though, that silicone sealant bring various applications that need a definite, waterproof seal. Instructions 1. Insert the clear silicone sealant in the caulking gun. The caulking gun is a round, metal cylinder that will receive a tube of silicone sealant. It features a metal rod within that pushes over the rear with the tube of silicone sealant and forces the sealant away from a little gem on get rid of the silicone tube. By pressing a handle on get rid of the caulking gun, it is possible to control how much silicone that's dispensed. 2. Silicone TubeTrim a tiny piece (about 2 inches long) off of the plastic tip located at the end of the sealant tube. The tube is approximately 1/8 inch wide in the very tip, also it flares over to 1/2 inch at the point where it attaches towards the cylinder of sealant. Begin with a little piece after which come to the desired hole size because you require to. 3. Poke a protracted nail up through end in the tip and pierce the foil seal located inside tip possibly at the bottom of the sealant tube.4. Press the tip contrary to the method to be sealed and gently squeeze the handle located near the top of the caulking gun. When you're carried out with the application, release pressure to succeed through the caulking gun by disengaging the metal rod with the handle. Failure to do this can result in sealant leakage. 5. Smooth the bead of silicone sealant out with your finger. Clear any excess silicone with a rag and paint thinner.

The characteristics and use of the silicone

Silicone main ingredient is silica, chemically stable, non-toxic. Silicone includes a strong adsorption capacity, can produce a person's skin drying effect. If your silicone in to the eyes, flush with a lot of water and seek medical therapy. Blue Silicone since it contains a modest amount of cobalt chloride, toxic, and food must be avoided contact and inhalation from the mouth, such as the occurrence of poisoning should immediately seek medical treatment. [Main Uses] on silica gel having a strong adsorption adsorption energy effectively sealed packages of moisture, chemically stable, non-toxic characteristics in conjunction with constant innovation and development in recent times, a variety of silicone continues to be widely used in drug purification, DNA isolation, food drying, high-precision electronics, fine cosmetics, sewage purification, beer purification, and advanced coatings and resin production or preservation areas. In our way of life and production and business activities, silicone is usually used in the following areas: precision optical instruments, electronic appliances dry mold packaging leather drying areas, such as placement in leather, leather bags, shoes play a drying shelf in the effect food drying areas, more prevalent in on biscuits and fried foods to make sure food crispy Drug drier side, invest vials, to ensure drugs prolong shelf-life container Drying: Shipping containers at different latitudes will form a box of "internal rain", the use of silica gel desiccant, it might absorb the equivalent of its own weight of water, as much as 50 days for ocean transportation process, can effectively lessen the dew reason for leaving the condensate container phenomenon in order. Class hotel with items, like the placing within the closet, shoes and bed, odor adsorption, maintain your air dry and fresh.

Silicone rubber use in medicine

Silicone rubber use in medicine will have a more promising future. Condensation type silicone rubber foam is a hydroxy-terminated silicone rubber as the base material, the foaming agent is a hydroxyl silicone oil, a vinyl platinum complex catalyst (heated catalyst dibutyltin dilaurate), in curing the foamed sponge-like elastic body made of a perforated at room temperature. To improve the quality of the foam also adding some other components, such as those containing silicone, so that the curing process to produce more gas; improve the texture and to reduce foam density. Join diphenylsilandiol not only to control the foam structure, but also to control the rubber viscosity increases during storage, but the amount is not too much, otherwise it will affect the electrical properties of the foam. In order to improve the physical and mechanical properties of the foam, a transparent silicone rubber may also be added. The catalyst complexes of chloroplatinic acid in an amount of vinyl not be too easy to operate, and may otherwise cause the operation is not conducive to an increase in viscosity; insufficient when the amount of catalyst, curing is incomplete, tacky surface of the foam, not elastic well, with a soft and plastic, intensity difference. Foam is liquid silicone rubber before vulcanization, suitable for potting material. After curing the foam at long-term use -60-159 ℃, after 150 ℃, 72hour old, or a 60 to 70 ℃ ten ten times using alternating hot and cold, still maintaining the original properties of the foam. Since the silicone rubber foam having a high thermal stability, good insulation resistance, insulation, moisture resistance, shock resistance, especially at high frequency shock resistance, and therefore it is an ideal lightweight packaging materials. For a variety of electronic components, equipment, instruments, instrument flying body can play quot wheels, moisture, shock, quot quot three anti-corrosion protective effect. But can also do the insulation sandwich filler material and salt spray atmosphere of floating materials and sealing materials. Silicone rubber foam padding in medicine but also as orthopedic, repair and re-clothing materials.
