As a kind of perferred technical scheme, the dry temperature conditionss are that initial temperature is 30~40 DEG C, with 1~4
DEG C/min be heating rate, gradient-heated is to 50~60 DEG C.
The circulation water law deslagging process that second aspect present invention provides during a kind of mineral fibre production is prepared
Mineral fibres.
Third aspect present invention provides described mineral fibres and is applied in paper industry, insulation material, refractory material.
Specific embodiment
The participation in the election detailed description for being preferable to carry out method of the invention below and including embodiment this hair can be more easily understood
Bright content.Unless otherwise defined, all technologies used herein and scientific terminology have common with art of the present invention
The identical implication that technical staff is generally understood that.When there is contradiction, the definition in this specification is defined.
Those skilled in the art of the present technique are appreciated that unless otherwise defined, all terms used herein (including technology art
Language and scientific terminology) have with art of the present invention in those of ordinary skill general understanding identical meaning.Should also
Understand, those terms defined in such as general dictionary should be understood that the meaning having with the context of prior art
The consistent meaning of justice, and unless defined as here, will not be with idealizing or excessively formal implication be explained.
A kind of circulation water law deslagging process during mineral fibre production, comprises the following steps：
(1) immerse：Mineral fibres is immersed in the immersion groove equipped with recirculated water, mineral fibres crude product is obtained；
(2) remove the gred：By step (1) chats fibres crude product by slag removing system, removed the gred；
(3) collect：When the slag ball rate of the mineral fibres processed through step (2) reaches 0.5~2%, by slagging-off in step (2)
Mineral fibres afterwards is by water pump, extracting；
(4) it is dehydrated：The mineral fibres that will be collected into is dried treatment.
Mineral fibres：
Mineral fibres belongs to mineral fibres, and its fragility is big, and dimensional stability is good, and difficulty is combined with organic fiber.Common mineral
Fiber is including asbestos fibre, sepiolite, attapulgite, shepardite, wollastonite, gypsum fiber basalt fibre etc..
In mineral fibres process, due to raw materials for production and into fine many reasons, the ore deposit produced such as not exclusively
The impurity such as chopped fiber, microcrystalline balls are mixed with fibres, these impurity have a significant impact to the quality of fibre, but due to fiber
In these impurity difficulties go out, the producer of most mineral fibres is not carried out except Slag treatment to mineral crude fibre, or pair with
The effect for not having suitable processing method or treatment except Slag treatment of mineral fibres is also unsatisfactory.
Slag ball
Slag ball of the present invention is defined as the general name of all solids impurity in mineral fibres.
Slag ball rate：
