Six tips for family security

1. What anti-theft measures should residential houses take?

1. Do a good job in neighborhood relations and look after each other when there is no one at home;
2. When conditions permit, keep as many people as possible in the home to reduce the amount of family outings;
3. Try not to store a large amount of cash, valuable securities and valuable ornaments in your home, and deposit them in bank safes as much as possible;
4. Install anti-theft doors of qualified quality, and the lower floor of the street can be installed with a barrier that is not easy to climb and does not protrude from the wall surface of the building;
5. A residential intercom anti-theft system should be installed in conditional residential buildings.

2. What issues should residents pay attention to when choosing anti-theft doors?

1. The prerequisite for the selection of anti-theft doors is that the manufacturer should have a production license issued by the Technical Prevention Office of the Municipal Public Security Bureau; the product specifications and models have been tested and qualified (with a test report); the sales unit has been issued by the Technical Prevention Office of the Municipal Public Security Bureau Anti-theft door sales permit; be careful not to buy cheap products in the morning market and on the street;
2. Adhere to the "tailor-made tailoring", the door and the opening are tightly matched, the screws are welded to death, and it is strictly forbidden to install the flat shot;
3. After the key is lost, the original manufacturer should be asked to change the lock in time to prevent it from being used by bad people;
4. The failure should be repaired in time, and cannot be used together. It can be used by the bad guys.

3. How should families with "two employees" consider anti-theft?

1. Check whether the doors and windows are closed before going out, take the key first, then lock the anti-theft door, don't forget to be at home;
2. Double-workers who work in three shifts should stagger their working hours. Be careful not to sing "Empty City Plan". They really don't work. They should turn on a small light at night and let the outsiders feel that someone is in the house through the curtains;
3. Don't hang the key around the neck when the child goes out with the key. Otherwise, it is equivalent to telling no one else in the house;
4. When educating the child to open the door by himself, pay attention to whether there are strangers nearby. Don't open the anti-theft door if the stranger calls the door. If it is a bad person, you can call 110 or call the neighbor.

4. What technical precautions can be taken for home anti-theft?

1. Install an automatic alarm door lock. Once illegally opened by a bad person, you can automatically call the user's pager, mobile phone, neighbor, neighborhood committee, and police station through the telephone line;
2. Magnetic control switch can be installed on the window, and an alarm signal can be issued once the window is opened;
3. Passive infrared intrusion detector can be installed in balcony or hallway;
4. Unit residential building can be installed with building intercom or video intercom anti-theft system;
5. If the community has an automatic police reception center, it should be connected to the network as soon as possible. In case of emergency, the community security and civilian police can rush to deal with it in time. Not much is spent, it is safe and worthwhile.

5. What problems can not be ignored in family security?

1. Buildings with patios, toilets and kitchen windows often become passages for criminals to enter the hall, and built-in protective fences should be installed to prevent them;
2. The key should not be placed in an obvious place to prevent outsiders from taking the opportunity to print the imitation system;
3. The passbook should be set with a password, and cannot be placed together with the household registration book and ID card;
4. When going out for a long time, you should greet your neighbors and ask for care;
5. For family travel, an automatic alarm device for local alarms should be installed; if there is a network connected to the alarm center, it should be filed at the alarm center and requested to be armed 24 hours a day.

6. How can the bungalow households guard against theft?

1. The courtyard door should be locked at night, and the surrounding wall should have anti-climbing measures. Do not accumulate too much debris inside or outside the wall to prevent thieves from using it as a climbing ladder;
2. The doors and windows of the residents should be firm and reliable, use anti-pry locks, and fences should be set up on the street;
3. Valuables should be placed in the safe, and the safe should be reliably fixed on the ground or wall to prevent moving. It can also be fortified with mercury switches, magnetic control switches, etc., and can give a harsh alarm when it is damaged or moved;
4. Neighbourhood watch and care for each other.

1. Product introduction

Quartz stone or silica, is a kind of silicate minerals that has hard texture, abrasion resistance, stable chemical properties` characters. Quartz Sand is crushing by quartz stone;it is white, colorless or translucent, the intrinsic molecular chain structure. Quartz sand is crystal shape  and variation lattice, which has high temperature resistance, the small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonant effects and its unique optical properties.

2. Application of quartz sand

Quartz sand is an important industrial mineral raw material, non hazardous chemicals,It is widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries; specific application performance for motor and train transportation:

a. Glass: flat glass, float glass, glass products (glass cans, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and anti radiation special glass and other main raw materials

b. Ceramic and refractory materials: embryo material and porcelain glaze, kiln with high silica brick, ordinary raw materials such as Silicon Carbide and carborundum.

c. Metallurgy: silicon metal, ferrosilicon alloy and silicon aluminum alloy and other raw materials or additives, flux.

d. Building: concrete, cementitious materials, road construction materials, artificial marble, cement physical properties testing materials ( cement standard sand) etc..

e. Chemical: as silicon compounds and water, glass and other raw materials; sulfuric acid tower filler, amorphous silica powder.

f. Machinery:the main raw material of machinery casting sand, grinding materials (sand, hard abrasive paper, sandpaper, emery cloth, etc.).

g. Electronic: high purity metal silicon, communication fiber etc..

h. Rubber, plastic: filler (to improve wear resistance)

I. Coating: filler (to improve the acid resistance of coating)

j. Aviation, space: the internal structure of molecular chain, crystal shape  and variation lattice, which has high temperature resistance, the small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonant effects and its unique optical properties.

3. Specifications of quartz sand:

Quartz sand filter:0.5-1 1-2 2-4  3-5 5-8 8-16 16-32mm 36 46 60 100 120.

Abrasives: 0.25-0.5 6-10mm 24 30 36 46 60 80 100 120 0.5-1 1-2 2-4 4-6 150200.

Quartz sand for floor brick: 60-80 80-120.

4. Transportation and Packing

Woven bag, lined with plastic film bags, each 25kg can also be packaged according to customer demand. The product should be placed in a cool and dry place during storage; When transportation, it prevents to mixed with hard materials, to affecting the quality of packaging, to prevent breakage. To avoid leakage or mixed with debris; to avoid water, oil and fire.
