Point.
Applicant states that the present invention illustrates the detailed process equipment of the present invention and technological process by above-described embodiment,
But above-mentioned detailed process equipment and technological process are the invention is not limited in, that is, does not mean that the present invention has to rely on above-mentioned detailed
Process equipment and technological process could be implemented.Person of ordinary skill in the field it will be clearly understood that any improvement in the present invention,
Addition, concrete mode selection of equivalence replacement and auxiliary element to each raw material of product of the present invention etc., fall in the protection of the present invention
In the range of.
