By the embodiment 1 in the present invention, embodiment 2 and embodiment 3 and the soft ceramic floor of in the market purchase, elastic comprehensive Closing two indexs of performance and anti-wear performance has carried out contrast test, and its method of testing and result are as follows:
Elastic integrated performance index method of testing, elastic index mainly tests elongation and response rate;
The assay method of the elongation of soft ceramics:
Test equipment, steel ruler(It is accurate to 0.1mm)With sign pen.
Sample clamp, jaws width is more than 50 millimeters.
Experimental condition, tested soft ceramics and control sample are made into the batten of 65 cm × 5cm wide long, perform 50cm marks Note;Balanced 4 hours under conditions of temperature is 21 ± 1 DEG C and humidity is 65 ± 2%.
Test, is continuously slowly stretched to 30N, stops 3 seconds, stops redrawing for 3 seconds after slowly lifting, reciprocal three times, the 4th Measurement markers size after secondary stretching.
Elongation is calculated, elongation %=(- 50 centimetres of size after stretching)/ 50 centimetres.
The assay method of the response rate of soft ceramics:
Test equipment, timer, meter ruler and tape(It is accurate to 0.1MM), static(al) extensibility tester;
Experimental condition, tested soft ceramics and control sample are made into the batten of 65 cm × 5cm wide long, are 21 in temperature ± 1 DEG C and humidity are to balance 4 hours under conditions of 65 ± 2%.
Operation, first determines elongation by the assay method of above-mentioned elongation;
By sample on the basis of original is long tensile elongation 80%, unclamped after fixed half an hour, measured after 1 hour Its length L1.
For example, elongation is 40%, then 50+50 × 40% × 80% centimetre, i.e., 66 centimetre are stretched to.
Elastic elongation response rate=(L1-50 centimetres)/ 50 centimetres.
Anti-wear performance index determining:According to GB GB/T 12988《Inorganic earth material polishing machine experimental technique》Enter OK.
Result of the test is as follows:
As can be seen from the above table, embodiments of the invention 1, embodiment 2 and embodiment 3 are equal in elastic performance and anti-wear performance Better than control sample.Control sample is the soft floor tile of Foshan plant produced from market purchase.
Soft ceramic recyclable regeneration new product in the present invention, also can reduce soil essence by materialization mechanical treatment, return Cultivate.

The abrasive member 111 can be manufactured with following high-carbbon iron alloys, its titanium 16%, carbon 6%, silicon by percentage by weight 3%th, lead 3%, tungsten carbide 8%, copper 0.3%, boron 5%, chromium 5%, balance of iron.
The difference of above-mentioned alloy exists, and common people think that copper is harmful element at for ferroalloy, it is impossible to make With, and together with tungsten carbide be added to when in ferrotianium copper by the present invention, greatly increases the wearability of ferrotitanium conjunction Energy.
Contrast of Wear Resistance method of testing and result that abrasive member of the invention is closed with the ferrotitanium bought on the market:
Method of testing, uses device, ML-10 type abrasive testers, 200# emery papers, a ten thousandth precision day It is flat.Sample rotation rate is 180 revs/min, and normal load power is 750N, and the time is 4 hours.
Result of the test:
As can be seen from the above table, abrasive member of the invention is good with anti-wear performance compared with the ferrotitanium bought on the market is closed Advantage.
Preferably, the dehydration equipment in the present invention can be realized using plate and frame filter press or high-power soil dehydration machine.
Preferably, the present invention can also include aniseed process part 5, to the aniseed discharged from discharge gate, first pass around big Material removal of impurities 51, the debris such as the metal in aniseed, bamboo and wood, plastics is sorted and is detected, then, by aniseed breaker 52, with broken Broken machine is crushed to major class, after crushing building stones can be used directly as construction material, in aniseed processing procedure produce Pug out can return to the first step of the invention as new pending material, be further processed.
