泡沫復(fù)合板的2種形式及回火知識

發(fā)布時(shí)間:2021-09-07 來源:http://www.gp552.com/

泡沫復(fù)合板不但使用方便,價(jià)格低廉,而且重要的一點(diǎn)是它綠色無污染。它的生產(chǎn)采用新的生產(chǎn)工藝,回收率有了明顯的提高。了解以上的知識是為了讓大家更好的對該產(chǎn)品的泡沫的2種形式有更好的理解。

The foam composite board is not only easy to use, but also cheap. And the most important thing is that it is green and pollution-free. Its production adopts new production process, and the recovery rate has been significantly improved. Understand the above knowledge so that we can better understand the 2 forms of the product's foam.

1、反硝化泡沫

1. Denitrification foam

如果污水廠進(jìn)行硝化反應(yīng),則在沉淀池或曝氣不足的地方會發(fā)生反硝化作用,產(chǎn)生氮等氣泡而帶動部分污泥上浮,出現(xiàn)泡沫現(xiàn)象。

If the sewage plant is nitrifying, denitrification will occur in the sedimentation tank or under insufficient aeration, resulting in bubbles such as nitrogen, which will cause some sludge to float and foam.

2、啟動泡沫

2. Start the bubble.

活性污泥工藝運(yùn)行啟動初期,由于污水中含有一些表面活性物質(zhì),易引起表面泡沫。但隨著活性污泥的成熟,這些表面活性物質(zhì)經(jīng)生物降解,泡沫復(fù)合板的泡沫現(xiàn)象會逐漸消失。

Activated sludge process started early, because there are some surfactant in the sewage, it is easy to cause surface foam. However, with the maturation of activated sludge, the foam phenomenon of foam board will gradually disappear after biodegradation of these surface active substances.

回火知識

Tempering knowledge

1、低溫回火:低溫回火所得組織為回火馬氏體。其目的是在保持淬火鋼的高硬度和高耐磨性的前提下,降低其淬火內(nèi)應(yīng)力和脆性,以免使用泡沫復(fù)合板的時(shí)候崩裂或過早損壞。

1. Low temperature tempering: the microstructure obtained by low temperature tempering is tempered martensite. The purpose is to reduce the internal stress and brittleness of the quenched steel under the premise of keeping the high hardness and high wear resistance of the quenched steel, so as to avoid cracking or premature damage when using the foam composite plate.

2、中溫回火:中溫回火所得組織為回火屈氏體。其目的是獲得高的屈服強(qiáng)度,彈性極限和較高的韌性。

2. Medium temperature tempering: the microstructure obtained by medium temperature tempering is tempered troostite. The purpose is to obtain high yield strength, elastic limit and high toughness.

3、高溫回火:高溫回火所得組織為回火索氏體。將淬火加高溫回火相結(jié)合的熱處理稱為調(diào)質(zhì)處理,其目的是獲得強(qiáng)度,硬度和塑性,韌性都較好的綜合機(jī)械性能。

3. High temperature tempering: the microstructure obtained by high temperature tempering is tempered sorbite. The heat treatment combining quenching and high temperature tempering is called quenching and tempering treatment. Its purpose is to obtain comprehensive mechanical properties with good strength, hardness, plasticity and toughness.

以上是關(guān)于泡沫復(fù)合板的2中形式以及回火相關(guān)知識的介紹到這里了,那么大家掌握了該知識后,就會在制造的時(shí)候更加的簡單了

The above is about the secondary form of foam composite panels and the introduction of tempering related knowledge, so after you master this knowledge, you will be more simple in manufacturing.
