Bright spot

Application elastomer coating on industrial fiber, also known as "fiber surface coating", is an important part of special fiber applications, including technology, textile and high-performance fibers.Help to improve the fiber in the fiber on coating of several features, including strengthening, windproof and waterproof properties, depending on the demand of the final product.This coating can be applied to clothing and rubber products, such as conveyor belt or car tyres.

What is the Fiber surface coating (Dip on Fiber)?

Fiber surface coating is basically with elastic properties of polymer.Usually, the coating is composed of carbon, silicon, oxygen and hydrogen.Elastic coating with viscoelastic and very low intermolecular forces.When applied to the fiber, is seal coating, performance for the adhesive, and protect the flexibility of the object.Sometimes, these coatings can be used to protect the soles, cover tyre, even for some controlled environment for insulation.

According to different, fiber, coating and application of coating amount was 25% to 5% and the weight of the range.The application of the fiber surface coating materials including:

Technology, textile and high-performance fibers
Wire or fiber monofilament
Polyester, polyamide, polypropylene, polyethylene, polyacrylonitrile fiber

The characteristics of

Only a small amount of calibration standard samples (3-5),
Is not affected by sample color or surface
Ensure complete step type measurement in 60 seconds
Due to the excellent temperature stability, magnets and magnet analysis has the very high repeatability

advantage

Brooke's small nuclear magnetic mqOne analyzer can quickly and accurately in the step type measurement analysis of fiber surface coating.Under normal circumstances, the application of fiber coating are based on different relaxation time of fiber and coating.Coating with mqOne system analysis, the first weighing fiber samples in test tubes to make sure the sample quality.The system measuring coating of fiber of nuclear magnetic resonance (TD - NMR) signal attenuation.Coating signal and fiber signal separation, its amplitude is associated with coating amount.

With wet chemical analysis, near infrared and gravity measurement compared to the other analysis methods such as brooke's small nuclear magnetic system has many advantages.MqOne system is applied to the analysis of fiber surface coating one advantage is that only a small amount of calibration standards.In addition, the system can provide less than 60 seconds step type measurement.MqOne has a high level of repeatability, this is mainly due to the excellent temperature stability magnets and magnet.

application

In order to analyze the nylon fiber coating, we measure the content of the five known coating samples used for calibration.Each sample prepared two spares.In small nuclear magnetic analyzer mq20 fiber oiling rate 18 mm load about 5 g sample in the sample tube, and 40 ° C in tempering before measurement.Reference is to use a gravimetric method.TD - NMR and the comparison between gravity measurement method is very clear: the results almost equals the reference value, see below

Example analysis technology

In the coating is analyzed on the nylon fibre, we know coating content was measured by a total of five samples of calibration.Two copies of the operator for each sample.Then, the operator in the brook small nuclear magnetic analyzer mqOne fiber oiling rate load about 5 g in 18 mm sample tube coating samples.These in vitro under 40 degrees Celsius for tempering, and use the gravimetric method to determine the reference value.Then, between TD - NMR and gravity measurement are compared, and the results show that looks almost the same as reference.

Analysis of fiber surface coating

Analysis on the fiber coating to determine whether the product before the market has a proper seal and/or coating is very important.Although this is an important part of the production process, but sure appropriate fiber coating is not always easy.In some cases, the coating level of analysis needs to be done quickly and continuously, evaluation methods should be improved.

Brooke is easy to operation of small nuclear magnetic mqOne analysis system can be used to analyze all kinds of fiber and fiber coating.At the same time the system is equipped with the calibration verification and calibration samples of transfer function.For most applications, the need of the calibration samples is very little, because in most cases only need three to five calibration samples.In general, from weighing empty sample tube to produce reports the results of the whole process takes less than 5 minutes, depending on the application type.
