About Nonwoven Fabric Material

Stage 1: 

Right after we planed to produce the masks ourselves, we begin to source the most important mask material – meltblown nonwoven material, the filter material.


We made the purchasing decision by touching the fabric and burn it, just like many videos on youtube telling how to distinguish meltblown nonwoven cloth, but this can tell you nothing about the quality, and the seller was the boss, people queued to buy.


The crazy fact was some suppliers sold out dozens of tons of so-called meltblown nonwoven fabric material, which turned out to be just normal pp non-woven.


Stage 2: Random testing is not enough

Ok, meltblown material testing became a phrase spreading the group of meltblown non-woven fabric testing equipment buyer, we began to tear pcs of the meltblown fabric roll as samples for further testing, once passed as qualified, we would pay the money, but this also could not stop the speculator's trick of mixing the fake ones with the good ones in one batch.


Stage 3: Quality is not the only thing needed to be considered

Slowed down the pace we made the purchasing, but we had to move on, so we scaled down the range of our suppliers, we decided to work with the manufacturer directly, and limited our selection to those factories which have their own quality control labs with instruments to test the fabric, and choose those who validated the quality of each roll, safety enough?


While it turned out that meltblown quality is just the cornerstone, we indeed bought the qualified meltblown nonwoven fabric material in this stage, but we ignored the other specifications, like the width, the package, the diameter of each roll, and etc, we failed to turn these meltdown to masks, due to these aspects that didn't seem important.


After these 3 stages, we found the solution finally, that comes to our current stage:


After so many trial and errors, we created the detailed standard for the meltblown fabric bursting strength tester material we looking for, and now we are only looking for well-known enterprises with their own quality standards(meeting our standard requirements), laboratories, quality control processes and capabilities, formal packaging and labeling specifications, etc.


For other suppliers, the answer is NO! the risk is too much, and unless you have a full set of quality control experience and corresponding capabilities (personnel and equipment), otherwise, 99.99% you will lose the money because they don't know whether they can do it, the only thing these suppliers can ensure you, is their low prices and swore to god that their quality is HIGH and No problem at all.

How to Hang a Suspended Ceiling From Steel Beams

The suspended ceiling hangs under the roof or floor structure above, hiding ugly mechanical and electrical equipment from the view, while also allowing you to easily reach these equipment as needed.While wooden frames usually support such ceilings, in rooms where metal frames are used instead of traditional wood, you can also hang ceilings from steel beams.Hanging the ceiling from the beam requires you to use a special clip to connect the support line to the beam without compromising its structural integrity.Measure 4 inch down from the bottom of the lowest beam, pipe or pipe in the ceiling space.If you plan to use panel fluorescent lamps in your ceiling, add an additional 2 inch to this measurement.Make a mark on the wall indicating the location of the facade.Set up a laser level to extend the mark you made on the wall to the entire wall length.Draw a chalk line on the wall to mark the position.Mark all four walls repeatedly with chalk lines indicating the height of the ceiling.Instal

Importance of Calibration Service, Material Testing

When it comes to Calibration services, genuine service providers offer full recall system and data sheets for all items calibrated. Service needs to be instrument specific. With the advent of technology, Calibration service has seen a tremendous change and has gone through various phases to get the top quality. Calibration is a great deal for industrial purpose. It makes sure that products are manufactured as per specification. It also checks the competence level of technically valid results. The calibrated measuring instrument helps in checking the quality and valuation of the product. In cases of electronic equipment, it is essential to calibrate instruments to keep a check on quality and performance. Calibration facilitates in improving measurement abilities. Calibration service can be manual or automated.  textile testing equipment manufacturers Material Testing machines are available for a wide variety of industries including materials testers for plastics, textiles, adhesives, fi

Level Measurement Solutions

Makeup water treatment is an important component of steam generation. It is the means to resupply the system with water suitable for boiler and other operations that, was lost in the cycle.The steam generation cycle, level control for the water treatment process is not necessarily about efficiency, but rather, accuracy, reliability and safety, while providing proper inventory management to ensure chemical and makeup water supply meets demand. The focus is on the chemical component of the makeup water treatment since it presents difficulties for level technologies that may work perfectly on non-chemical applications related to the water treatment process or those with limited variations in the contents of the vessel's vapor space. Although important measurements such as ammonia, acid, caustic and other chemical storage tanks are not difficult level applications by any stretch, small nuances in how the vessels are monitored relative to level technology can have a dramatic effect on t
