The change of the times The finished furniture is getting less and less recognized by consumers. The house prices are getting more and more expensive, and the housing area is getting smaller and smaller! Too much consumption can't afford it. Furniture can effectively use the entire space according to the actual needs of the apartment! Nowadays young people like to play DIY, the personality is, the fashion is to be different, the play is to be different! Custom furniture also meets this point.
The benefits of custom furniture are so much, but we still have to pay attention when shopping. Let's take a custom wooden door as an example!
Control cost
Customized wooden doors must strictly control their own costs, otherwise you budget 5,000, the result is 20,000 is normal. Relatively speaking, the more expensive the material, the better. And the more comfortable the appearance is. Door panels, door panels, hardware accessories, Roman columns, waist lines, top lines, etc. These are all money. But for very people, wooden doors are used to get in and out. The need for decorative features is minimal. Don't spend money and say you should pick it up again. It’s not enough to cash in ten hands every time.
2. Environmental protection is very important
Since the door of the wooden door mainly adopts solid wood particle board, multi-layer solid wood board and finger jointed wood board, a certain proportion of urea-formaldehyde resin or phenolic resin is added in the production process of these artificial boards. This is also the source of formaldehyde for many panel furniture. Therefore, when purchasing the wooden door body, it is preferred to choose a plate with a lower formaldehyde emission. According to environmental protection standards, it can be divided into E0, E1, E2 grade plates. Don't be too cheap for plates. The best choice for E0!
3. Order contract
Whether you are buying a finished product or customizing a contract, you will need to sign a contract with the merchant. As a customized product, all the accessories you choose will have a more comprehensive contract. This is also an effective basis for the final quality assurance of the product.
4. Installation acceptance
There is a unique aspect of custom wood doors that ultimately requires professional installers to install. Then you can pass the acceptance check and sign by the relevant acceptance form army!
Concerned about surprises
Label: Four points that custom wooden doors have to say
Previous: Door industry hardware accessories and fixing Next: Water-based wood lacquer construction in high temperature and high humidity weather, don't forget
Reflective Concave Blazed Holographic Gratings
Concave Gratings are critical components in a variety of spectroscopic instrumentation.They are quite useful in analytical instruments,ranging from food analysis to plastics manufacturing and process quality assurance.They are also ideal for applications in optical communications,biotechnology, colorimetry,chromatography,and medical instrumentation.
China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300x300mm2 for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns.
