The bable sampler is a special sampler for paper and paperboard to measure the water absorption and oil permeability of standard samples. It can quickly and accurately cut the samples of standard size. It is an ideal auxiliary test instrument for papermaking, packaging, scientific research and quality supervision and inspection industries and departments.
Beater degree tester is suitable for detecting the capacity of water filtration rate of diluted pulp suspension, that is, the determination of beater degree.
Introduction
Melt-blown cloth has the characteristics of small pore size, high porosity and high filtration efficiency, and is the core material of mask production. This instrument refers to GB/T 30923-2014 plastic Polypropylene (PP) Melt-blown Special Material, suitable for polypropylene as the main raw material, with di-tert-butyl peroxide (DTBP) as the reducing agent, modified polypropylene melt-blown special material.
Methods the principle
The sample is dissolved or swollen in toluene solvent containing a known amount of n-hexane as internal standard. An appropriate amount of solution was absorbed by microsampler and directly injected into gas chromatograph. Under certain conditions, gas chromatographic analysis was carried out. DTBP residue was determined by internal standard method.
PL7-C Speed Dryers Is a used in paper-making laboratory,it is a laboratory equipment for paper drying.The machine cover, the heating plate is made of stainless steel (304),far-infrared heating,By thermal radiation baking 12 mm thick panel.Hot steam through cover fleece from the eduction in mesh.temperature control system use intelligence PID controlled heating. Temperature is adjustable,The highest temperature can reach 150 ℃. The thickness of the paper is 0-15mm.
Our this hand sheet former is applicable to research and experiments in papermaking research institutes and paper mills.
It forms pulp into a sample sheet, then puts the sample sheet on the water extractor for drying and then carries out the inspection of the physical intensity of the sample sheet to appraise the performance of the raw material of pulp and beating process specifications. Its technical indicators conform to the international & China specified standard for papermaking physical inspection equipment.
This former combines vacuum-sucking & forming, pressing, vacuum-drying into one machine, and all-electric control.
