Immersion Testing

Applicable products: Suitable for rubber industrial impregnated products such as impregnated curtain fabric, impregnated canvas, impregnated rope, impregnated fabric skeleton materials, etc., covering tires, tapes, hoses, rubber shock absorbers, and industrial rubber products with impregnated skeleton materials.

Applicable materials: Covering textile substrates such as nylon, polyester, aramid, cotton, and viscose fibers, as well as specialized materials for impregnation such as natural rubber, styrene butadiene rubber, nitrile rubber, chloroprene rubber, and water-based/solvent based impregnation solutions.

Applicable scenarios: Used for raw material incoming inspection, impregnation process validation, finished product factory acceptance, adhesive performance evaluation, durability testing, quality arbitration, and quality inspection of rubber product supporting skeleton materials.

Appearance and size inspection: surface coating uniformity, no exposed substrate, no glue spots, no broken wires, no defects; Detect width, thickness, line density, warp and weft density, twist, dimensional deviation, and evaluate appearance defects.
Physical and mechanical performance testing: testing of breaking strength, elongation at break, constant load elongation, elastic recovery rate, peel strength, tear strength, rope tensile properties, and fabric stiffness.
Immersion bonding performance testing: evaluation of bonding strength (H pull-out force), immersion amount, bonding uniformity, thermal bonding strength, and dynamic bonding performance with rubber to verify the reliability of fabric rubber bonding.
Thermal and dimensional stability testing: testing of thermal shrinkage rate, dry heat shrinkage rate, high-temperature dimensional stability, thermal stress relaxation performance, and high-temperature mechanical performance retention rate.
Aging performance testing: hot air aging, ozone aging, UV aging performance, testing the strength retention rate, elongation retention rate, and adhesive strength retention rate after aging.
Process adaptation performance testing: evaluation of impregnation uniformity, adhesive layer adhesion, wear resistance, flexural resistance, fatigue resistance, and textile processing adaptability.
Environmental adaptability testing: water resistance, oil resistance, acid and alkali resistance, moisture and heat resistance, salt spray resistance, evaluate the stability of impregnated products under harsh environments.
Composition and process testing: impregnation solid content, curing degree of adhesive layer, fiber composition analysis, and verification of impregnation process parameters compliance.
