Ano ang mga katangian na dapat subukan para sa nababaluktot emulsions? Ano ang mga paraan ng pagtuklas?

Flexible emulsyon ay isang uri ng emulsyon na may kakayahang umangkop polimer bilang pangunahing bahagi. It is different from the traditional emulsion, it has excellent flexibility, scratch resistance, paglaban sa tubig, tibay ng katawan, elasticity and other characteristics. Common flexible polymers include acrylate copolymers, neoprene, silicone rubber, polyurethane, atbp. Flexible emulsion is widely used in plastics, mga materyales sa gusali, Tela, mga electronics, automotive, medical and other fields, can be used to prepare a variety of high-performance materials, mga patong na patong, mga pandikit, sealing materials, elastomers, atbp.

Paraan ng pagtuklas
The following is a brief description of the test methods for common performance parameters of flexible emulsions:

Solid content: The coating sample was dried to a constant weight at about 105 ° C, and the ratio of the mass of non-volatile substances to the total sample mass was calculated.

Lagkit: Use equipment such as rotational viscometer or dioptometer to measure the viscosity of the paint.

Pamamahagi ng laki ng tinga: Devices such as particle size analyzers are used to measure the size distribution of particles in flexible emulsions.

Halaga ng pH: Use PH meter and other equipment to measure the pH of the paint to evaluate the stability and performance of the paint.

Pagdikit: Use tensile testing machine, shear testing machine and other equipment to measure the adhesion of the coating and the substrate surface.

Tibay ng buhay: evaluate the weather resistance, wear resistance and chemical resistance of the coating by simulating the exposure and wear tests in the actual use environment.

Pagkalastiko: Use material testing machine and other equipment to measure the elasticity and deformation ability of the coating.

Lakas ng paghatak: Use equipment such as tensile testing machine to measure the maximum capacity of the coating under tensile force.

Scratch resistance: Use equipment such as a scratch resistance meter to simulate the scratch and wear in actual use, and evaluate the scratch resistance of the coating surface.

Water resistance: Use water immersion tester and other equipment to evaluate the waterproof, moisture-proof and permeability resistance of the coating.

Ipinapaalala namin sa iyo: different performance parameters may require different test methods and equipment, at maaaring may ilang mga pamantayan at pagtutukoy ng industriya, for flexible emulsion performance testing, but also should be selected according to the actual needs of the corresponding test methods and standards. Kasabay nito, the test conditions and standardized operations need to be strictly controlled during the experiment to ensure the accuracy and reliability of the test.
