dental machine history

Tablet press tablet press appeared in Europe earlier, there are nearly a hundred years of history. In China in 1949, Shanghai Tianxiang Hua Kee Iron Works imitation caused British 33

Punch tablet press; 1951, according to the U.S. 16-punch tablet machine converted into a domestic 18-punch tablet machine, which is the earliest domestic manufacturing pharmaceutical machinery; 1957, designed and manufactured

ZP25-4 type tableting machine; curing light 1960, to design and manufacture successful 60-30 type tableting machine, with automatic rotation, compression function, pressed varieties tablets, sugar tablets,

Calcium, coffee tablets. The same year also design and manufacture a type ZP33, ZP19 type tabletting machine.

In the 1970s began Shanghai Daiichi Pharmaceutical Machinery Factory (Shanghai Tianxiang's predecessor) and Shandong Medical Instrument as compression tableting machine tablet press sentinel manufacturers large

Production ZP series tablet press. "Plan" period, the Department of Aerospace 206 HZP26 successfully developed high-speed tablet presses. In 1980, the Shanghai Pharmaceutical Machinery Factory first system designed to

Made the ZP-21W type tableting machine, to the early 1980s the international advanced level, is the first domestic product. 1987, the introduction of the Federal German Fette company microcomputer control

Manufacturing technology, design and manufacture of P3100-37 rotary tablet press with automatic control tablet weight, pressure, automatic digital film, films and other features automatic elimination of waste, closed

Structured, the degree of purification to GMP requirements. 1997, the annual Shanghai Pharmaceutical Machinery Co., Ltd. Tianxiang Kin developed ZP100 series rotary tablet press, GZPK100 Department

Column speed rotary tablet press.

In the 21st century, with the deepening of GMP certification, in full compliance with the GMP ZP series rotary tablet machine have appeared: Shanghai's ZP35A, Shandong Liaocheng ZP35D

And so on.dental supply companies High-speed rotary tablet machine production, the pressure signal acquisition and rejection and other technology has been developed rapidly, the highest yield is generally greater than 300,000 / hour, the most

Large pre-pressure 20kN, 100kN maximum principal stress 80kN or more. For example, the Beijing Science and Technology Co., Ltd. Sinopharm Long Li GZPLS-620 Series High Speed ​​Rotary Tablet Press,

Shanghai Tianxiang Jian Pharmaceutical Machinery Co. GZPK3000 series high speed rotary tablet press, Beijing Aeronautical Manufacturing Technology Research Institute, PG50 Series High Speed ​​Rotary

Sheet machine.

With the level of manufacturing process technology, automatic control technology to improve and tableting machine manufacturers use a variety of special needs, a variety of special-purpose tablet press

Have also emerged. For example, laboratory ZP5 rotary tablet machine for dry powder tabletting rotary tablet press machine for gunpowder explosion-proof ZPYG51 series tablet

Rotary tablet machine.

Three Mistakes of cleaning teeth

Three Mistakes of cleaning teeth

Myth one: daily brushing, teeth cleaning can be described as superfluous
In developed countries, has become very popular teeth cleaning routine dental care, people generally once or twice a year to find their dentist regularly to clean teeth. Therefore, we are now the most important is a correct understanding of cleaning teeth, changing concepts. Cleaning teeth cleaning teeth completely different from ordinary light surface dirt, it can not be completely removed by ordinary brushing to remove plaque, calculus, and deposited on the tooth surface of the pigment, thereby enabling organizations to maintain periodontal health, prevention and treatment of periodontal disease; and easy to find when cleaning teeth tiny imperceptible dental problems, such as the relatively hidden caries, to achieve the purpose of early detection and early treatment. Under normal circumstances, teeth cleaning as a routine care in six months or a year wash, for patients with periodontitis, you need the Magnetic Name Badge guidance of a doctor for regular teeth cleaning.
Myth: cleaning teeth can damage teeth, worn tooth enamel surface
A lot of people kind of concerns, cleaning teeth will wear away the enamel surface of the tooth. In actual fact, ultrasonic scaler, it is the principle of ultrasonic vibration, not worn out, no harm to the teeth, the needle does not have any cutting function, is to rely on high-frequency ultrasonic vibrations to break calculus, but also in cleaning teeth after By polishing, sandblasting in the teeth externally applied layer of protective film, slowing the speed of the stone again.
Myth: beauty salon and a few small clinics have clean teeth, there faster than a regular hospital, more convenient
Now if there is a dental clinic, hospital, generally have clean teeth this service, even the little salons magnet system also have such service, and very cheap. But the doctors spoke of the need to promote clean teeth, but also to secure formal. In some small clinics or beauty salon, and its rapid irregular teeth cleaning teeth cleaning methods will give those who have adverse consequences for cleaning teeth's enamel damage itself, forming the naked eye can not see the surface scratches, but also damage to the gums, increased periodontal disease, the most serious yet easily cause cross-infection, without safe disinfection of instruments is very easily transmitted viruses such as hepatitis and AIDS, to give people cause trouble. In the regular hospital by medical personnel are dedicated to the operation, the most commonly used is the ultrasonic scaler, the instrument, the needle should be strictly disinfected.
