PL4-2 23L laboratory speed governing valley beater

23L laboratory speed governing valley beater

PL4-2

The PL4-2 23 liters frequency conversion modulate velocity the Valey beater (the Valley beater) are the papermaking laboratory international standard equipment, is studies the pulping paper technology the necessary equipment, this machine through flies the mechanical action which the knife roll and the bed plate produce, carries on the cut-off, bruising each kind of textile fiber pulp, to rub, the fission, Run to rise with the textile fiber refinement, simultaneously has cell wall's displacement and the distortion, the primary wall to the textile fiber and this lives the wall outer layer the breakage. According to exerts pressure to the bed plate with the beating time, may obtain the different freeness paper pulp and so on change,the Valee beater widely uses in each kind of vegetable fiber, the synthetic fiber, the coal textile fiber, the glass fiber beating experiment, is the papermaking production chemical examination, the quality control, the craft formulation, the teaching scientific research test.

This machine satisfies ISO 5264/I, TAPPI T200 as well as GB 7980187 laboratory beating Valee the (Valley) beater law (Pulps-laboratory beating-Valley beater method) and so on standard requests. This type besides may change the heavy thallium pressure, the beating time, meanwhile has the frequency conversion velocity modulation system, so that the user can may choose the change to fly the knife roll rotational speed, thus obtains the different experimental result.  

This machine has the frequency conversion speed adjusting gear, the fly cutter may achieve the very high rotational speed, after downloading the bed plate heavy thallium, may complete to paper pulp fast clearing out.

Principle: And has the normal concentration thick liquid after the measurement in Valey between the (Valley) beater's fly cutter and the bed plate the beating, in the beating process carries on the sample once in a while, and surveys the paper pulp the degree of ionization.
