Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、繊維補強無機質板の抄造方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for making a fiber-reinforced inorganic board.
セメントスラリーを抄造して製板する場合、石綿を無配
合とすると、セメント等の粉体原料がワイヤーシリンダ
から抜は落ち、抄造歩留が低下する、及び濾水量が増加
し、種膜が不均質になるため製品の地合が悪くなると言
った問題がをる。When making sheets from cement slurry, if asbestos is not added, powder raw materials such as cement will fall out of the wire cylinder, the papermaking yield will decrease, the amount of drainage will increase, and the seed film will not be formed. This causes problems such as poor product consistency due to the homogeneity.
そこで、石綿無添加の場合に、これを補うためパルプを
添加することが行なわれる。Therefore, when asbestos is not added, pulp is added to compensate for this.
ところで、パルプを添加する場合、パルプを所定の濾水
度まで叩解し、均一な材質とすることが通常行なわれる
が一定の濾水度まで均一にパルプを叩解するには別途、
叩解工程を必要とする上、その工程管理も必要となり工
数が増加すると言った問題が有った。By the way, when adding pulp, it is usually done to beat the pulp to a predetermined freeness to make it into a uniform material, but in order to beat the pulp uniformly to a certain freeness, a separate process is required.
There was a problem in that it required a beating process and also required process control, which increased the number of man-hours.
この発明は、上記問題点に鑑み、石綿に代え、パルプを
添加する場合、パルプの叩解工程を省略し、あるいは、
叩解するにしても簡単に終了し得る改良された繊維補強
無機質板の抄造方法を得ることを目的としてなされたも
のである。In view of the above problems, this invention omit the pulp beating process when pulp is added instead of asbestos, or
The purpose of this invention is to provide an improved method for manufacturing fiber-reinforced inorganic boards that can be easily completed even if beating is performed.
抄造効率を高めるためのパルプの濾水度は通常カナディ
アン濾水度で４３０〜４７ｋｌとされる。そこで、種々
濾水度のパルプであって、濾水度の異なるものを混合し
、これらの平均濾水度が上記範囲となるようにすれば、
結果として充分な濾水度が得られる。The freeness of pulp for increasing the papermaking efficiency is usually Canadian freeness of 430 to 47 kl. Therefore, if pulps with various freenesses are mixed and their average freeness falls within the above range,
As a result, sufficient freeness is obtained.
即ち、未叩解の濾水度の高いパルプと未叩解の濾水度の
低いパルプとを混合し、その平均濾水度を所定の値とす
れば、全（叩解工程を要することなく所定の抄造効率と
することが出来る。In other words, if unbeaten pulp with high freeness and unbeaten pulp with low freeness are mixed and their average freeness is set to a predetermined value, the total It can be made efficient.
また、特に濾水度の低いパルプで、所定のものが得られ
ない場合は、この部分のパルプのみを叩解し、濾水度の
高いパルプとの平均濾水度が所定値となるようにするの
である。In addition, if the specified pulp cannot be obtained especially with a pulp with a low freeness, only this part of the pulp is beaten so that the average freeness with the pulp with a high freeness becomes the specified value. It is.
なお、上記混合バルブの添加量は全固形分に対し６％以
上とすることが望ましい。Note that the amount of the mixing valve added is preferably 6% or more based on the total solid content.
この理由は、６％より少ないと充分な抄き上げ効率とな
し得す、本発明の効果が得られなくなるからである。The reason for this is that if it is less than 6%, sufficient paper-raising efficiency cannot be achieved, but the effects of the present invention cannot be obtained.
次に、この発明の詳細な説明する。 Next, the present invention will be explained in detail.
〈実施例１〉
未叩解のパルプであって、カナディアン濾水度（以下単
に濾水度と言う）が７０７ｍ ｌ、及び未叩解のパルプ
であって、濾水度が１１４ｍｌのものを同量ずつ配合し
、該配合バルブを無石綿とされたセメントスラリーに供
給し、ワイヤーシリンダーで種膜を抄造し、これを積層
して製板した。<Example 1> Equal amounts of unbeaten pulp with a Canadian freeness (hereinafter simply referred to as freeness) of 707 ml and unbeaten pulp with a freeness of 114 ml The blending valve was supplied to asbestos-free cement slurry, and a seed film was formed using a wire cylinder, which was laminated to form a plate.
このときの抄造歩留、濾水速度、地合等は別表の通りで
あった。The papermaking yield, drainage rate, formation, etc. at this time were as shown in the attached table.
なお、別表において比較例は、添加されるパルプをすべ
て均一に濾水度４５７となるまで叩解処理したものであ
る。In addition, in the comparative example in the attached table, all the added pulps were uniformly beaten until the freeness level was 457.
〈実施例２〉
セメントスラリーに添加必要量の濾水度が７０７ｍＡの
パルプのうち、その半量のみを濾水度１１０となるまで
叩解し、これを残りの未叩解のパルプと混合し、実施例
１と同様な抄造を行なったところ、実施例１と同じ結果
が得られた。<Example 2> Of the required amount of pulp with a freeness of 707 mA to be added to the cement slurry, only half of it was beaten until the freeness became 110, and this was mixed with the remaining unbeaten pulp. When papermaking was carried out in the same manner as in Example 1, the same results as in Example 1 were obtained.
〈実施例３〉
濾水度が９００１１１１２のパルプを濾水度が１００ｍ
ｌとなるまで叩解処理し、次いで、その半量を取り出
し、残りのパルプを濾水度が１１０ｍｌとなるまで叩解
し、先のパルプと混合し、これを必要量、石綿無添加の
スラリーに添加し、実施例１と同様の抄造を行なった。<Example 3> Pulp with a freeness of 90011112 and a freeness of 100 m
The remaining pulp was beaten until the freeness reached 110 ml, mixed with the previous pulp, and the required amount was added to the asbestos-free slurry. The same papermaking as in Example 1 was carried out.
この場合も実施例１と全（同様な結果が得られた。In this case as well, the same results as in Example 1 were obtained.
この発明は、以上のように構成されているので、石綿無
配合のセメントスラリーにパルプを添加する場合、濾水

としないか、叩解処理をするにしても従来に比し、その
処理が著しく簡略化されるため、省エネルギが図られる
といった効果を有する。Since this invention is configured as described above, when adding pulp to asbestos-free cement slurry, pulps with different freenesses are mixed and the average freeness is adjusted to a predetermined freeness level. Because of this structure, there is no need for beating treatment at all, or even if beating treatment is performed, the treatment is significantly simplified compared to the conventional method, so it has the effect of saving energy.
