teeth correction stunned important to you

Many types of dental abnormalities or defects, some small, there is a simple, but also complex.
Tooth color abnormalities such as tetracycline, dental fluorosis, discolored teeth and so on. Alignment of teeth abnormalities such as crowding dentition sparse, misplaced teeth and so on. Dental abnormalities, such as twist angle

Turn teeth, tilt teeth and so on.
For example there is a large jaw deformities, including the mandibular prognathism or mandibular prognathism, anti together to open and close, a small jaw and so on. teeth jewelry The teeth deformities or defects in shape and size, there are teeth

Abnormalities, such as too small teeth, conical teeth, enamel hypoplasia, shaped teeth, a variety of causes crown defect or crack.

dental machine operating principles

The punch and die during tableting by the pressure, common bearing steel (such as crl5 etc.) production, and heat-treated to increase its hardness.

Many types of punch, punch tablet shape determined by the desired shape. Press the structure and shape of the die can be divided into round, shaped (including polygonal and curved);

Punch the shape of a flat-shaped cross-section, bevel-shaped, shallow concave, deep concave and integrated shape. Flat-shaped, bevel-shaped punch for pressing flat cylinder-shaped tablets,

Shallow concave biconvex portable dental unit tablets for pressing, deep concave mainly for press-coated tablets of the chip, integrated shape mainly used to suppress shaped plate-shaped. In order to facilitate the identification and services

Used drugs in the end face of the die can also be engraved the name of the drug, dosage and vertical and horizontal lines and other signs. Suppression of different doses of tablets, you should select the appropriate size of the die

.

(2) tablet press tablet press working process of the work process can be divided into the following steps:

① undershoot punch position (its working position facing up) into the Central die hole in the bottom die hole, seal the hole bottom mold;

② The Araliaceae is to fill in the hole in the mold drugs;

③ punch on the red parts (its working position down) from the falling upper die hole in the die hole and down a certain stroke, the powder into tablets;

④ ascend out of the hole punch, punch up the tablets under the top of the hole in the mold, to complete a tabletting process;

⑤ undershoot down in place, ready for the next fill.

(3) tablet tablets principle mechanism

① dose control. Tablets have various requirements of different doses, the large dose regulation is accomplished by choosing different diameters of the punch die to be achieved, if the diameter 6mm

, 8mm, 11.5mm, 12mm, etc. punch. Die size is selected, the tiny dosage adjustment by adjusting the lower punch inserted into the depth of the hole in the mold, thus changing the back cover

After the actual length of Dental Autoclave the die hole, adjust the die hole filling volume of the drug. Therefore, in the tableting machine should have under the regulation of the die hole punch in the original location of the institution,

Dose adjustment in order to meet requirements. Because different batches of powder preparation total hematocrit differences, this regulation is necessary.

At a dose control, the operation principle of the feeder also has considerable effects, such drugs are by weight of particulate, free-rolled into the die hole, its loading condition

More loose. If using multiple compulsive way into the environment, the die hole will be filled with more drugs, filling the situation is more dense.

② tablet thickness and compaction control. The dose is determined according to pharmacopoeia prescription and can not be changed. For storage, preservation and disintegration time requirements,

Tabletting pressure of a dose is also a requirement, it will influence the actual thickness and appearance of the tablet. Tableting pressure regulation is essential. This is done by

Adjusting the upper punch holes in the mold downlink capacity to achieve. Some compression tableting machine during operation only on the red down, but also to act as a lower washed by

Relative motion upper and lower punches together to complete the tabletting process. But mostly by adjusting the pressure regulator on the red down the amount of pressure regulating agencies to implement and control.
