Abstract
The utility model discloses a free carbon sample decomposing device capable of replacing a platinum vessel. The free carbon sample decomposing device comprises a boiling water bath device and a sample dissolving device. The sample dissolving device is of a cup body structure (1), a cup opening diameter (2) is larger than a cup bottom diameter (3), and the cup body is made of organic polymeric materials. The boiling water bath device comprises a plurality of support feet (4) and a cover plate (5) arranged above the support feet (4). The cover plate is provided with a plurality of round holes (9), the diameter (8) of each round hole is larger than the cup bottom diameter (3) of the sample dissolving device and is smaller than the cup opening diameter (2) of the sample dissolving device, a base plate (6) is arranged below the cover plate (5), and a heating water tank (7) is arranged between the base plate (6) and the cover plate (5). The free carbon sample decomposing device is resistant to corrosion of hydrofluoric acid-nitric acid mixed acid, enables a free carbon sample to be dissolved, can replace existing expensive platinum vessel free carbon sample decomposing devices, reduces cost, and is convenient to carry.
Description
Technical field
The utility model belongs to uncombined carbon sample decomposer field, relates to a kind of can the corrosion by hydrofluoric acid resistant-nitric acid acid mixture, replaces the device that the uncombined carbon sample is analyzed in the dissolving of platinum ware.
Background technology
At present, all refractory metals comprise the analysis of the carbonide Free Carbons such as tungsten, molybdenum, tantalum, niobium, zirconium, hafnium, titanium, vanadium, chromium, all use platinum dish, the analyzing and testing sample is made sample dissolution with the acid mixture of hydrofluorite-nitric acid, residual uncombined carbon is measured the uncombined carbon amount with the carbon analyzer device after filtering.
Platinum is expensive, and a platinum dish weight is about 40g ~ 50g, and its price is more than ten thousand yuan, and in using a small amount of loss is arranged, and the keeping of platinum dish is also very inconvenient.
Simple glass vessel, silica ware can not hydrofluoric acid resistants, other metalware such as iron crucible, nickel crucible, silver crucible, ceramic crucible etc. are hydrofluoric acid resistant not also, adopt a kind of cheap material that can replace platinum dish, solve the sample resolution problem of uncombined carbon, very necessary.
The utility model content
Problem for prior art, the utility model aims to provide a kind of uncombined carbon sample decomposer that replaces the platinum ware, this device can corrode by hydrofluoric acid resistant-nitric acid acid mixture, can dissolving analyze the uncombined carbon sample, can replace existing expensive platinum ware uncombined carbon sample decomposer, save cost, easy to carry.
In order to reach above purpose, the technical scheme that the utility model provides is:
A kind of uncombined carbon sample decomposer that replaces the platinum ware comprises boiling water bath device and sample dissolution device, and described sample dissolution device is a cup body structure, the rim of a cup diameter greater than cup at the bottom of diameter, and cup is the organic polymer materials cup; The cover plate that described boiling water bath device comprises a plurality of legs and places leg top has a plurality of circular ports on the cover plate, the diameter of circular port is greater than the cup end diameter of sample dissolution device, and less than the rim of a cup diameter of sample dissolution device; Below cover plate, be provided with base plate, be provided with heating water tank in the middle of base plate and the cover plate.
Described organic polymer materials cup is preferably Polyvinylchloride cup, polycarbonate cup or polyvinylidene fluoride cup.
Described organic polymer materials cup wall thickness is preferred 〉=0.5mm.
Described cover plate is preferably corrosion resistant plate, thickness of slab 〉=2mm.
The below makes further explanation the utility model:
Along with the fast development of organic polymer materials, can find the polymeric material of a kind of hydrofluoric acid resistant, nitric acid corrosive attack, replace platinum dish.Such as Polyvinylchloride (CH
2CHCl) n, popular name PVC, polycarbonate (enlightening fluon), the materials such as polyvinylidene fluoride (fluoroplastic-2) all have the performance of hydrofluoric acid resistant, nitric acid, can be used as the material that replaces platinum dish.Material is made cup-shaped so that sample dissolves therein.
According to above scheme, designed simultaneously a cover boiling water bath system, the cup-shaped sample-dissoloing unit that fills hydrofluorite, nitric acid is put into wherein, heating is dissolved sample in boiling water bath.
The course of work is: take by weighing a certain amount of metallic carbide matter sample, put into sample dissolution device (molten sample cup), add a small amount of water-wet after, add again hydrofluorite, drip nitric acid, after question response is steady, molten sample cup is put into the circular port of boiling water bath device, in boiling water bath that sample dissolution is complete.
Compared with prior art, the beneficial effects of the utility model are:
1, adopts the utility model device, can save the cost of buying platinum dish, exempt the required proof box of keeping expensive instrument etc.
2, the more convenient operation of dissolution sample is quick.
