Polyvinyl chloride resin apparent density tester

Polyvinyl chloride resin apparent density tester,XF-1636The apparent density tester for raw material powder in plastic profile factories is mainly used to determine the apparent density of loose plastic material left in a specified funnel. It is used to determine the apparent density of polyvinyl chloride resin and is an ideal testing instrument for quality inspection of raw materials entering the chemical industry and plastic profile factories. The product complies withGB/T3402、GB/T1636Waiting for standard requirements.

Scope of application: This method is suitable for measuring the apparent density of powder molded plastics, which is the mass per unit volume, providing parameters for the packaging of molded plastics, the design of mold cavities, and extrusion screws.

Technical parameters:

Main components: base, support frame, funnel, insert plate, feeder

Receiver volume:100ml±0.5ml

Sampling quantity:110ml-120ml

Funnel:AType and upper diameter56mm, lower caliber33mmBThe shape and funnel angle are:40Degree, aperture is8mm

satisfiableK-6721(1966)The requirements

Testing requirements:

1. Sample: Extract samples according to product standards.

2. Experimental instruments:（1）Balance: Sensitivity0.1can2）Surface Appearance Tester（3）Measuring cylinder type measuring cup:100ml

3. Experimental steps:

（1）Place the funnel on the instrument with its small opening at the bottom directly above the measuring cylinder20-30mmAnd try to be coaxial with the measuring cylinder as much as possible.

（2）Insert the baffle into the funnel and100+5mlPour the sample into the funnel.

（3）Quickly remove the stopper plate and allow the test to flow freely into the measuring cylinder. Use a scraper to scrape off any excess sample from the upper part of the measuring cylinder and weigh the sample in the cylinder on a balance, accurate to0.1Ke.

（4）Each batch of materials shall be tested three times (tested samples shall not be reused)

5、 Calculation method for test results of apparent density tester: apparent density of mold material（Da，g/mL）Calculate according to the following formula

Where:m——Measure the mass of the sample in the cylinder (grams)v——Measure the volume of the cylinder（100cm3）

The experimental results are expressed as the arithmetic mean of three measurements, taking two significant figures.

Apparent density of polyvinyl chloride resin（g/mL）According to the formula（A1）Calculate

In the formula:m2——The quality of the receiver and sample,g; m1——The quality of the receiver,g; v——The volume of the receiver.mL(i.e100mL）. The relative error between the single measured value and the average value of parallel samples is greater than2%time,Must be redone.

Take the arithmetic mean of the test results of two parallel samples.
