Cement acceptance
Cement should have a product certificate, in addition to different varieties, different grades of cement can not be mixed, such as plaster cement used mostly for Portland cement, its strength level should not be less than 32.5, so we in the acceptance of cement, you should first identify The specific use of cement. In addition, there is a shelf life of cement, the shelf life is relatively short, usually 3 months, beyond the shelf life of the cement will not only reduce the adhesion and even agglomeration, such cement, the supervisors advise not to use.
Yellow sand acceptance
The soil content in the inferior yellow sand is too high and the landlord should pay attention when inspecting it. In addition, the hand is also used to feel the delicateness of the yellow sand. If the yellow sand particles are too thick, you can raise objections to the decoration company.
Large core board acceptance
The side of the big core board generally has the manufacturer's trademark, production address, date, and anti-counterfeit labels. The first thing to check is whether the brand, specification, model, etc. are consistent with those specified in the contract. The excessive formaldehyde content in the Daxin board has great harm to the human body, so we should also look at the Daxin board's quality inspection report or other quality assurance documents provided by the manufacturer. See if the formaldehyde content meets the E1 environmental requirements. Finally, the supervisor suggested that we look at whether the surface is dry, clean, how dense the core material is, and whether there are any problems such as deformation, rot, pods, or wormholes. The regulations in the industry stipulate that one side of the big core board must be a whole piece of wood board, and the other side can only allow one patchwork. Everyone should pay attention to it.

Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.
Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
