With the emtec ACA Ash Content Analyzer, a new way to measure the total mineral filler content as well as the percentage content of the individual filler components of paper and board, is finally introduced to the pulp and paper industry worldwide.

With the Ash Content Analyzer (ACA), emtec Electronic aims to overcome the disadvantages of the traditional combustion method. The innovative lab instrument replaces combustion with x-ray technology, enabling the non-destructive measurement of individual mineral fillers in paper and board shown as combined or separate results. Time consuming test procedures are no longer necessary, because the data are available for e.g. process optimization in less than one minute.

Common practice in pulp, paper and board industry

In the pulp, paper and board industry, mineral fillers and fines are used to influence the characteristics of the paper, either internally or on the surface. Typical fillers are for example calcium carbonate, kaolin, titanium dioxide, talcum and barium white. If recycled pulp is used in the production, an additional element of uncertainty are the fines and fillers, which are already included in the recycled material. To optimize the necessary additional amount of fillers and fines used in the production, the existing amount of fillers and fines within the waste paper needs to be known. If fillers and fines can be added optimally, the quality of the finished product increases.

Emtec test equipment enables a very exact evaluation of the relevant paper and board properties

Elof Hansson and emtec Electronic at ACOTEPAC 2020 in Cali, Colombia

From February 12th to 14th emtec presents its innovative measuring instruments for the pulp, paper and board industry at the ACOTEPAC conference (booth no. 56). The use of these devices enables a more efficient and reliable process and quality control from the wet end to the finished product and helps to achieve the best possible quality at the lowest possible costs.FPA touchCAS touch Website

At the ACOTEPAC interested visitors can take a look at the Charge Analyzing System CAS touch! and the Fiber Potential Analyzer FPA touch!, two devices, which measure the particle charge and the surface charge of fibers. The easy handling, light weight and small size makes them an ideal partner. What the FPA touch! achieves with high accuracy in the laboratory, its “big brother”, the Fiber Zeta Potential Analyzer Online FPO achieves directly in the production process, to which it is directly connected. Up to four fully automatic measurements per hour are possible. The results can be provided online, but can also be transferred to the computer system of the mill. The permanent control allows an immediate reaction, in case it becomes necessary.

Together with our Colombian partner Alberto Marin, from Elof Hansson, our area manager, Daniel Ohndorf, will attend the conference of the Colombian papermakers once again in 2020. Besides the wet-end test devices CAS touch! and FPA touch!, the EST12 emtec Surface & Sizing Tester will be presented at the booth. By the help of the device, the surface sizing or more general the surface hydrophobia and the surface pore structure of paper and board can be evaluated. Both parameters have a big influence to the converting relevant quality characteristics printability, coatability and gluability.

Objective measurement of softness, roughness, stiffness and the recovery parameters elongation, hysteresis and plasticity

Emtec Electronic with innovative testing instruments at TITAS 2019 in Taipei

IMG 6133Leipzig, Germany 23.09.2019 - For the fourth time, the German company emtec Electronic GmbH will present its innovative testing equipment to the textile industry, together with the Chinese and Taiwanese representatives Mr. Max Liu (Jiu Mao) and Mr. Chiang (TechOne). Please visit our booth no. L527a to have a look at the device and to get a detailed explanation of:

The TSA – Tactile Sensation Analyzer. The device enables an objective evaluation of the softness, roughness and stiffness of a textile fabric. Included into the softness measurement is the measurement of the viscoelastic, elastic and plastic properties, which are represented by the elasticity, plasticity and hysteresis. With an extra module, the compressibility can be measured.

The FPA and CAS touch! are two instruments, which are very interesting for the textile industry as well. The FPA measures the surface charge of the fibers (zeta potential), which provides information about the efficiency of the interaction of certain additives with the textile fiber. The CAS touch! is able to show how long and stable certain additives stay on the textile fiber.
