Environmentally friendly water-based silicone water-based silicone Shu

Printing silicone mesh: 80-120 mesh gauze generally used, but also the flexibility to choose (such as network printing using 200-400 mesh mesh) screen frame depending on the printing effects: aluminum frame, wooden frame can be, the best blade aluminum frame : water / oily, flat / sharp blade can be. The flexibility to choose according to operating practices. Recommended: Oil knife stencil thickness: general do planks, hanging slabs sensitive adhesive with about 4 times, but also the flexibility to choose depending on the particular printing effects (such as dot hit color printing with a sheet) sets of plastic: the best water-based glue sets, oil Taiwan gum can sometimes cause sensitive adhesive curing silicone difficult: water oil dual sensitive adhesive best, thick slabs need sensitive adhesive wash water network: 407 printing water or white oil, white oil chemical name is n-hexane, and said 6 #, 120 #, 200 # solvent gasoline silicone printing: printing silicone powder two components 1, A component: a colorless transparent gel, there are printing silicone series, glue and other clothing 2, B component for curing agent When adjusting the curing rate of speed, with the support of drying agent and retarder 3, Segao: is printing special silicone colorant, silica gel and creams ratio of 10: 1 (the ratio can be adjusted according to actual needs, but Segao ratio of more than 20% will affect the adhesion of silica gel and otherness of) 4, low viscosity silicone, and finally made the cover face light effect with a low viscosity silicone also add B agent, also 10: 1 ratio is generally added 10 in the printing silica gel % -100% low viscosity silicone do cover surface (depending on size of the pattern) a low viscosity silicone may be added up to the same weight of silica gel with silk, silk silicone component can not exceed the low viscosity silicone lid surface without also highlight effect, but not very bright, according to utilize specific effect. Process: 1, color plastic: the approximately 100% (according to the actual needs toning, this ratio may fluctuate, but the proportion of floating is not recommended for over 20%) of silica gel was added in creams, stir, to obtain the desired color plastic, 2, reinforcement toner: The colored plastic and hardener at 10: 1 ratio Stir the gel to complete 3, Printing: Silicone pour a good tune to start printing network version bottoming: Usually 2-3 the end to break even, A plastic: B gum = 10: 1 color: usually 2-3 times, enough to color, in A gum was added to 10% of silica gel creams flaps: A glue in Riga 10 % -100% low viscosity silicone, low viscosity silicone plus the more the more light, low viscosity silicone but also 10% of B agent; a bright enough to be printed twice, concrete is dry flexibly according to the effect: each of these print a table can be printed on a second dry 4, vulcanizing: according to the actual needs of the finished printed heating and drying, or put to dry naturally drying the higher the temperature, the faster you can cover up so that after leveling silicone bake again Do not immediately high temperature baking, otherwise there will be bubbles or pinholes special effects: 1, color: You can print one or more print depending on the desired printing effect, many times in print, every time India finished dry and then Indy Second, all printed after their baking 2, multicolor: Reference monochrome printing, India finished first after drying printing additional color, after all India finished and then drying thoroughly 3, chromatic: The Indian background, namely benchmarking may, when color printing, the background must be dry, all the colors print after all, then drying thoroughly to 4, Right Angle: Screen 1-5% silica plus adjuvant (right angle aids), multiple printing namely may 5, fillet: When backing may be slightly dilute, slightly oblique blade and screen, multi-pass printing, mainly cover the surface tackiness of the level, and finally to cover up how much glue nowadays determine their angle. Common problems and solutions: 1, no cure for two reasons: First, the proportion of the curing agent added is not strictly 10: 1, and the other reason is that the fabric or cloth containing background makes silicone poisoning chemicals (nitrogen) N , S (sulfur), P (phosphorus), AS (arsenic) will play a toxic reaction, resulting in slow solidification or quit 2, delamination: When printing, each printed on a table next dry after printing, all printed after their completely dry, otherwise it is easy delamination 3, surface leveling, not bright: the need to re-adjust glue or adding an appropriate amount of a low viscosity silicone to increase its liquidity at the last printing. 4, surface leveling, not bright: After printing silicone inside a bubble, because the adhesive is too high, thick stencil, bake too fast, the surface is not flat, covered surface pinholes because the viscosity is too high bake in a hurry due. After printing the need to open the table fan, blowing air bubbles broken, do not use guns or dryer immediately baking, given a little time (3-5 minutes) so that the natural leveling and baked silica, silica surface or dry, the effect of air bubbles remain inside. Note: 1, the production process of the necessary electronics, the proportion of A, group B component to be weighed accurately, otherwise a great impact on the curing time, may lead to serious quit 2, B agent before hard shake.
