Put the cooling oil, and scrape a layer off the surface of the cooling oil every time. Generally, a box of cooling oil can be used for 2 ~ 3 months

I remember that in the past, the burglar proof doors at home were all made of steel tubes and bars stretched vertically and horizontally. It is necessary to install another door inside for sound insulation and heat preservation. There is only a solid burglar proof function requirement for the hollow door outside. Today's security door can be said to be the combination of the past two doors. With a solid steel door plate and an anti-theft lock, unsafe factors can be completely isolated outside the home

when we hand over our personal and family property to this unique anti-theft door, have we ever thought that if it is not strong enough and realistic enough, if it is a little greasy and frivolous, it will mercilessly betray our trust

when the distance between home and the outside world is only one door, we should be safe and secure, not frivolous

why can't the security door be opened?

it looks like a solid security door, but its door plate and lock are weak, and thieves can easily break through the door or unlock the door to enter the house. CCTV recently broadcast the "weekly quality report" column to question: why has the security door become so unbearable to open? The reporter visited the security door market and found that some manufacturers used protective doors, pry proof doors and even armored doors to sell as security doors. They also cut corners in the selection of materials. The retail price of some security doors was as low as 300 or 400 yuan. According to relevant sources, many anti-theft doors do not need to be prized at all, and can be opened without damage, trace and technology. The complaint rate of anti-theft doors that are not anti-theft is rising

the national quality supervision department recently found that 70% of the products of small anti-theft door factories are unqualified, and many anti-theft door factories use iron sheets instead of steel plates, resulting in the easy deformation of the anti-theft door when subjected to external forces. Some low-end products use paper shells and honeycomb paper as fillers, which collapse over time, and do not have anti-theft, sound insulation and heat preservation properties at all. The production of anti-theft doors must have the "production license registration certificate" issued by the public security department, but according to the reporter's interview, more than 30% of the brands cannot provide this certificate

the new national standard for burglar proof doors will be issued

in the face of a series of violations in the burglar proof door market, a new standard formulation seminar composed of experts from the three institutes of the Ministry of public security and a number of domestic burglar proof door production enterprises was held in Wuxi recently to revise the original national standard respectively. Among them, the abnormal opening time of the anti-theft door is determined as 30 minutes, 15 minutes, 10 minutes and 6 minutes; The length of the lock tongue is not less than 16mm; The number of locking points shall be no less than 8, etc. The introduction of these new regulations will play an extremely important role in regulating the production and sales of anti-theft doors

in view of the current situation in the market of anti-theft doors under the banner of "entrance door" and "protective door", which are mixed with good and evil people and deceive consumers, a new regulation was specially made when formulating the new standard this time, that is, from next year, all anti-theft doors must be marked with the words of security level (a, B, C, D, special) on the upper left corner of the door, and permanently fixed on the upper corner of the hinge in Song typeface gravure printing 1.60m above the ground with a positive and negative error of 10mm. The specific time is to strive for full implementation in the first quarter of 2007. Relevant experts said that only anti-theft doors can be marked with this mark, which will effectively and intuitively prevent the mixing of fake and inferior anti-theft doors, and let consumers buy anti-theft doors that can really prevent theft

how experts sit in court to choose burglar proof doors

burglar proof doors are a link that is easy to ignore in the decoration process, but it is the most important link. There is a good door that can be "closed by one man and closed by ten thousand men", so that life has no worries at home. How to identify the advantages and disadvantages of anti-theft doors, we invite relevant experts to help you:

1. Level standard: the security level of anti-theft doors can be divided into level a, level B and level C, of which level C has the highest anti-theft performance, level B is second, and level a is the lowest. Most of the security doors we see in the building materials market are class a security doors, which are more suitable for ordinary families

2. Check the filler: the standard filler now is foaming agent, which can keep heat and sound insulation. The disadvantage is that the fire prevention performance is poor, but there is no problem to achieve the anti-theft effect. The better one is slag cotton. It is best to ask the manufacturer to indicate what kind of filler to use when buying. When installing the anti-theft door, you can generally see what is inside by screwing the cat's eye off the door. If some cat's eyes have been fixed and can't be screwed off, you can see it when installing the door lock. If you find that the filler is wrong, you can discuss with the manufacturer based on this

in addition, you can also check whether there is an anti-theft keel lining in the anti-theft door. The anti-theft keel generally has two types: grid shaped and S-shaped. S-shaped saves material, but it is not as strong as grid shaped. If there is no anti-theft keel inside, the anti-theft performance will be greatly reduced. 3. Check the steel plate: Although the anti-theft door is made of steel plate on the surface, the steel plate is also different from the steel plate. According to the national regulations, the thickness of the steel plate of the anti-theft door should reach 1mm, but the thickness of the anti-theft door made by some small workshops can't reach at all, and some are only 0.4mm. The thin plate loses the meaning of anti-theft, and it can be opened with a pry

in addition, the steel plate of the security door should be cold-rolled. Cold rolled sheet has good extensibility and toughness, but the price is relatively expensive. Therefore, some manufacturers use hot-rolled sheet to replace it in order to save costs. The simplest way to identify the anti-theft door is to knock on the door plate with your hand. The sound sounds solid, indicating that the steel plate is thick enough and the filler is solid. If the sound sounds "poof poof", it means that the steel plate is not thick enough

4. Good locks don't depend on the number of lock points: many sellers of anti-theft doors say that they have more anti-theft lock points when selling, but in fact, this is just a cover to attract customers. A really good lock is not that the more lock points, the better. There is no essential difference between four lock points and 10 or 20. No matter how many lock points there are, the center is on the lock cylinder. If the lock cylinder is broken, no matter how many lock points there are, it is useless. The anti-theft door with qualified lock generally adopts three-dimensional lock. Not only the door lock is locked, but also the upper and lower crossbars can be inserted and locked to fix the door

5. Process quality: special attention should be paid to check whether there are welding defects, such as open welding, no welding, missing welding, slag inclusion and so on. Check whether the door leaf fits tightly with the door frame, whether the gap is uniform, whether the opening is flexible, whether all joints are dense, whether the paint plating is uniform, firm and smooth, etc. The high-quality anti-theft doors are embedded with rubber sealing strips on the door frame, so there will be no harsh metal collision sound when closing the door

6. Beware of the trap of renovated doors: when buying anti-theft doors, you should also avoid the trap of renovated doors. Some small stores selling anti-theft doors on the street will recycle some old anti-theft doors, and then sell them after renovation. You can observe the turnkey process

generally, the packaging of the new anti-theft door is intact. The installer packs it in front of the customer. The key is in the packaging, and the packaging of the key is also complete. Install the lock core in front of the customer, and then give the key to the customer. If the package of the door itself is damaged, and the key is in the worker's pocket, it may be a renovation of the door

consumers had better go to the formal home building materials city to buy anti-theft doors, because the sale of anti-theft doors in the formal building materials city must be approved by the special administrative department of the Public Security Bureau, and the building materials city generally requires the stationed merchants to provide relevant certificates for the sale of anti-theft doors. In addition, you should also check the production registration approval, quality verification certificate, inspection report, fire prevention inspection report, sealing test report, etc

7. Buy with caution if it is less than 700 yuan: at present, the 1mm thick steel plate panel on the market is 7200 yuan per ton, and the hot-rolled steel plate for door frame is 6500 yuan per ton. If it meets the national standard, the cost of making a steel plate for an anti-theft door will need 500 yuan, plus the cost of locks, fillers, painting and so on. The cost price is generally not less than 700 yuan. The framed weight of a qualified anti-theft door should be more than 60 kg. If the price is lower than this price and the weight is insufficient, consumers should buy it carefully
