Now more and more people choose invisible curtains. There are many sellers of invisible screens in the market, but the price and quality are very different. So how to choose high-quality yarn invisible window? Below we will bring the purchase skills and maintenance of invisible screen windows for your reference.

Selection skills of invisible screen window;

1 First, we should choose a regular screen window manufacturer to ensure its product quality and after-sales service.

Friends who have used the invisible screen window will find such a problem: when the screen window needs to be pulled down in spring or retracted in autumn every year, the screen window cannot be pulled freely, and the screen window is separated from the slideway. That's because there is too much dust in the spring without pulling the screen for a long time, which makes the spring lose its elasticity. In addition, some parts lost or damaged due to decoration, aging or other reasons need to be maintained and repaired by the original manufacturer. (Special note: Invisible screen windows are similar in appearance, but the profiles and parts of each manufacturer are different, so various accessories between manufacturers cannot be matched. )

2. Select the frame material of the invisible screen window.

At present, there are three kinds of screen window materials on the market:

A, the first one is all aluminum alloy. This profile is frost-proof, sun-proof, anti-aging, not easy to deform and durable, and can be painted in various colors according to the color of the window frame. Its service life is more than 20 years, and it is the most durable screen window profile at present. But its wall thickness is different, ranging from about 0.7_ to about 1.0_. Of course, the thicker the wall, the more durable the profile.

B, the second one is all made of PVC. This kind of profile has low cost, but it is afraid of freezing and sun exposure, easy to burn, easy to age and not durable. It is divided into raw materials and recycled materials. As the name implies, raw materials are profiles extruded from raw materials, and the life of this screen window profile is about 2-3 years. The recycled materials are melted and extruded from recycled waste plastics, and the cost is particularly low. In some wholesale markets, you can buy a set for more than ten dollars. However, our company reminds you never to buy this kind of screen window, except that it is hard and brittle, easy to age and has a life span of several months. It is toxic, pollutes the environment and harms your health, so we remind you to pay special attention when buying.

C, aluminum alloy and PVC material collocation, that is to say, some parts use aluminum alloy material, and some parts use PVC material. At present, most of the handles on the market are made of aluminum alloy, and the yarn box, chute and bottom groove are made of PVC. In fact, the vulnerability of the bottom slot is second only to the handle, so the use of aluminum alloy materials can greatly improve the service life of PVC screen windows. (Special note: At present, the outer frame of invisible screen window on the market is not made of plastic steel. The so-called "plastic steel" refers to PVC profiles with steel lining inside, which are used to make windows. However, the profile of the outer frame of the invisible screen window can't be lined with steel at all, so the company specially reminds everyone not to believe what those vendors say when buying screens. )

You can choose the frame material of the screen window according to your own economic situation or the length of use, because the frame material is the most direct reason to determine the price of the screen window.

3. Select the screen window with invisible screen window.

At present, stainless steel mesh, iron mesh, plastic (ethylene) mesh and fiber mesh are common. Among them, stainless steel mesh and iron mesh are not suitable for invisible screen windows because they are relatively hard. Plastic net is low in cost, but it has peculiar smell, is easy to burn, sticky on the surface, easy to hang ash, afraid of freezing and sun exposure, and easy to age. The fiber web is woven by glass fiber monofilament plastic-coated flat weaving process, and after heat setting, the warp and weft are bonded. Smooth surface, good air permeability and filtration performance, flame retardant, antistatic, easy to clean, no deformation and long service life. It is a relatively high-grade product among domestic gauze types at present.

4. Mass of bobbin and spring in yarn box

The spool material is the same as the outer frame material, and it can also be divided into PVC material and aluminum alloy material; It is best to choose galvanized spring, which is not easy to rust and has strong durability.

5. Selection of switch buckle

At present, there are three main ways to hang invisible screen windows on the market: one is snap-in, made of plastic, iron and Bai Gang. Plastic materials are easy to age and break; Iron sheet is easy to rust and not durable; White steel is not easy to rust and break, and it is the most durable buckle at present. The other is magnetic collision, which uses the characteristics of magnets to connect the handle with the bottom slot, but after a long time, the magnets will demagnetize, so that the screen window will not be hung. There is also a direct use of profiles to hang. If you choose this hanging method, it is best to choose aluminum alloy handle and bottom groove.

6. The windproof effect is good or bad

The windproof effect of the screen window depends on the windproof setting on the one hand and the spring force in the yarn box on the other, so the windproof effect cannot be generalized. At present, windproof devices mainly include windproof buckles, windproof rods, windproof needles, windproof coats, etc., all of which have certain windproof ability.

7. Installation method

At present, most invisible screens are installed with plastic parts. Although this installation method is simple, the plastic parts used are easy to age and break. Even if the outer frame is intact, once the plastic parts are damaged, the whole screen window will be paralyzed. There is also a direct nailing method, that is, the outer frames such as yarn boxes and slideways are directly screwed on the window frame with self-powered nails, so that the outer frames of the screen window are firmly attached to the window frame, thus prolonging the service life of the screen window.

8. Choice of price

The material of the outer frame is the most direct reason to determine the price of the screen window. A, all PVC screens have the lowest price, and the quality of each screen is only thirty or forty yuan; B, PVC and aluminum alloy screens, the price mainly depends on how much aluminum alloy is used. The more aluminum alloy fittings, the higher the price of screen window; C. If the whole frame and bobbin are aluminum alloy screens, the cost will be higher and the retail price will be higher. The unit price per screen is about 100 yuan. The bigger the specification, the more special the color, and the higher the price. Although the price of this kind of screen window is high, if it is well maintained, its life span will be more than twenty or thirty years.

Maintenance and cleaning of invisible screen window;

opening hours

When it's windy and rainy, roll up the gauze before closing the window. If the gauze floats out due to strong wind, it should be stuffed into the track first, and then the screen window should be pulled. When the wind is too strong, it is recommended to turn down the windows or not use screens.

Pull material

When pulling the clamping net rod, pull it parallel to the track. If you accidentally pull the net clamping rod out of the track. First, tilt the net clamping rod, put both ends of the net clamping rod into the track respectively, and then gently pull it several times (pay attention to whether the upper and lower gauze are rolled back horizontally when pulling). The screen doors and windows will be repaired without affecting the future use effect.

Surface maintenance

If the surface of the frame is accidentally worn, Bellevue can be used to scrub or spray self-paint.

Open state

When the gauze doors and windows are not in use, the gauze should be put away to avoid the influence of closing the gauze doors and windows for a long time on the service life of the spring and the cleanliness of the gauze.

Reduce trampling

It is forbidden to stomp on the aluminum profile forcibly, so as not to damage it.

Screen cleaning

Screen window cleaning does not need to be disassembled, it can be cleaned by pulling the screen window, or by tapping the screen with a feather duster. If the kitchen screen window is stained with oil smoke, you can gently wipe the gauze with a wet cloth dipped in detergent and then wipe it with a wet cloth, and then roll it back after the gauze is dry.
