Affect the performance of the main parameters plastic box

Maximum particle size; viscosity; curing temperature; regular price ion content; molecular size;20x4 lcd permittivity

Plastic box factory adaptive testing methods and criteria:
Viscosity: A, Test Method: Test test box gluing degree.
B, criteria: viscosity within the parameters provided by suppliers and the final viscosity is similar to the production of frames.
Screen Performance: A, Test Method: Silkscreen at current production process conditions tested plastic box, observe the printing results.
B, criteria: full uniform lines, screen width is less than or equal to the current production of plastic box.
Curing performance and reliability: A, test method: the production process according to the present conditions of the sealant cure.
B, criteria: cure completely cured product was boiled four hours frameless plastic cracking and leakage phenomenon; warp-400C freezer four hours after the frameless plastic cracking and leakage phenomenon.
Reactive with the liquid crystal: A,mini lcd module test method: plastic box to be tested according to the production process conditions for the test sample, test its optical properties.
B, Criterion: plastic box near the viewing area without extending in a direction toward the domain. Does not affect the optical parameters on the LCD, optical properties after high temperature and humidity changes reliability requirements in the product range.
