During the renovation, the owner “in person†to supervise the quality and progress of the project naturally can not be less, even if it is all-inclusive can not be completely "hand shake dispensers." However, good steel must be on the cutting edge. It cannot always pounce on the construction site 24 hours a day. Therefore, it is necessary to first understand what is the focus of supervision of the target, to achieve a targeted. Grassroots construction supervisors make a smart eye The grass-roots construction is the foundation of all constructions, and the construction of the grass-roots level is well done so that the subsequent processes will be smoother and the renovated wall will be more durable and beautiful. As an owner, do you know little about the basic construction? Let's take a look. 1, slot considerations When retrofitting additional water-supply pipes and wires, they should not be thrown horizontally in the wall surface, and should be thrown vertically. This is because horizontal damage has a great deal of damage to the wall, and it is very resistant to earthquakes and strength. It can only be thrown vertically and horizontally. Can't exceed 3-5 cm. If the slot is deep, it is easy to hit the steel in the wall and saw the steel bar broken. If the slot is shallow, it will be easy to bulge in the future. 2, material inspection First of all, we should pay attention to the behavior of the foreman to steal the column, or the material provided by the company, and then use additional materials to fill up the empty, once there is a problem, maintenance will be unclear after the sale. In addition, the classification of materials placed to avoid pollution, the formal decoration company will generally put the project schedule and supporting tools placed in a prominent position, the decoration site is also relatively clean. Decoration materials should be placed in categories and materials that are easily contaminated with each other should be placed separately. 3, anti-crack inspection The construction of the wall often runs through the entire process of the renovation. If there is a wall of wood or modeling, it will be entered in the early stage of construction. If only the paint is painted, it will start work in the middle and later stages. But for the construction of the wall, the painting of the paint often goes through many procedures such as puttying, sanding, brushing, primer, etc. If it is not carried out in strict accordance with the construction specification, if the brushing is not in place, or if it does not wait until the previous If a process is dry enough to carry out the next process, it will be prone to wall cracks and cracks. Xiaobian Weapons: Material placement can not change the physical properties of materials, can not cause mutual contamination of materials, can not cause material deformation, can not cause security risks, can not cause damage to the packaging. For example, ceramic tiles cannot be placed on sand or cement, and buckets that have been painted or painted cannot be placed on plates. Decoration construction knowledge decoration experience
This lens is made of curve shape, not sphere. The aspherical lens has surface, shown in parabolic surface and polynomial expression. Ellipsoid, hyperboloid, fourth curved surface are examples,Aspherical lenses are designed to reduce spherical aberration
aspheres, are available molded, CNC-polished, or MRF-polished, either with or without anti-reflection (AR) coatings. Aspheres are often employed to collimate light exiting a fiber or laser diode. The surface of an asphere is designed to eliminate spherical aberration.
An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.
Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations, We could provide plano convex aspheric lens, plano concave aspheric lens, double convex(biconvex)aspheric lens
