A few technical terms of the liquid silicone rubber-HongYe silicone

Writer:TcoglorSource:www.szrl.net Date:2013-04-22

Knowledge in order to make everyone a better understanding of the Silastic particular, we refer to a number of professional terminology.
(1) the use of time
    After the two-component liquid silicone rubber base and curing agent mixed, you can use the operating time. Generally should be noted that the temperature and relative temperature of the working environment.
   Table dry time
   One-component RTV silicone rubber exposed to the curing process in the atmospheric environment, with your fingers touch the surface stickiness disappears, the sticky hands of time. Generally should be noted that the ambient temperature and relative humidity of the curing. Dry, sometimes also known as the finger touch drying time.
  (3) base material
    Read the main component of the complex two-component liquid silicone rubber. Sometimes referred to as the main agent.
(4) rubber
    By the base polymer, the curing system, filler, operating aids, and special functional additives formulated into the end of the sulfide complexes. Specific rubber composition of products due to the different varieties of performance requirements.
(5) curing agent
  Two-component liquid silicone rubber, by mixing with the base material, the occurrence of cross-linking curing component.
6. Priming agent
  To improve the adhesion to the substrate surface and the liquid silicone rubber is glued to the substrate surface pre-coated liquid material coating the bottom, also known as the primer.
7.U-based materials
  Without curing agent mixing silicone rubber.
8 sealant
   Waterproof, weather, dust, and materials for structural materials gap to fill. Seal and to adapt to the displacement effect.
9, Adhesive
   Means the role of the sticky, can sticky material by chemical or physical combination of a class of substances, also known as sticky adhesive.
10 extrusion
   Sealants with the extent of extrusion of difficulty in the construction of the injection material. Generally refers to the diameter of the injection material in the construction and the pressure exerted.
11 sag
     Sealant to the vertical access Feng fill weight the degree of sagging, also called flow.

12 self-leveling nature
 Injection of liquid silicone rubber to the horizontal seams or container, the surface energy of the natural shape in the horizontal plane.
13 of thixotropic
    The standing state of deformation, imposed certain easy flow shear, lifting shears time and in the non-deformed state. Is one of the important construction performance of the sealant.
14 polluting
      Cured liquid silicone rubber, uncured composition and plasticizer exudation pollution caused by their own and the surrounding material, a phenomenon also known as the Migration.
15 modulus
    Specimen, the force required in the units of the initial cross-sectional area means the elastomer in the physical test, produce a certain elongation, also known as tensile strength or tensile stress. Sealant in accordance with the size of the modulus divided into high, medium, low modulus three.
16 displacements ability.
      Affected by temperature, humidity, wind, earthquake, vibration and other building materials scaled, the seams filled sealant followers the amount of movement, the general said that by stretching the width of the joint width ratio of stretching before.
17 The tensile adhesion
    Sealant to vertically stretch the adhesive and the substrate surface to be sticky. Usually H - shaped specimen the maximum tensile stress, the breaking elongation.
 18 The tensile adhesion
    Sealant to vertically stretch the adhesive and the substrate surface to be sticky. Usually H - shaped specimen the maximum tensile stress, breaking elongation and cohesive failure rate, said.
19 cohesive failure
     The liquid silicone rubber substrate adhesion structures, subject to external damage, breaking the abbreviated symbol for the CF in the state of the rubber layer.
    20 bonded destruction
      The liquid silicone rubber substrate adhesion structures, subject to external damage, breaking in the state of the rubber layer, simple symbol for the AF.
21.UL standard
     By Underwriter Laborotories Inc. to develop the internal security assurance specifications. UL 94 for the combustion of the plastic materials.
