原料になる事に着目した。However, it was observed that bacteria that use glycols as substrates were not present in the extract. Therefore, it is quite possible to produce petroleum products without the need for petroleum by adding small amounts of glycols. Therefore, since conventional plastics are very often dependent on petroleum for their components, the filtrate of the present invention reacts in a chain reaction with the glycols present in the plastic raw materials, and the filtrate also becomes a new plastic material. We focused on its use as a raw material.

。During this reaction, especially when left to stand still, the temperature may be in any range as long as the bacteria can be active, but generally the temperature is 100°C.
It is preferable to carry out at a temperature of ℃ or less, especially room temperature to 60℃ or less,
The mixing time may be as long as the mixture becomes pulp-like (porridge-like), but the mixing time is generally 3 hours or more. After allowing this to stand for a while, it is filtered to obtain a filtrate.

物を除錆剤とするものである。Plastic raw materials (monomers, reaction intermediates, etc.) and plastic materials, which will be described later, are added to the filtrate, and the mixture is stirred for several hours or more and allowed to ferment, yielding a liquid product divided into three phases (Figure 1). The temperature during this stirring and brewing is the same as in the above case. The three phases are, in order from the top, a liquid first phase (a), a semipermeable membrane-like liquid viscous phase (b) having ion exchange properties, and
and a third phase (c) which is a liquid-viscous phase. This first phase liquefied product is used as a rust remover.
この第１相の液和物は次のものからなるものと推定され

酸性液による公害問題等は解決される。The liquid phase substance of the first phase of the plastic modified product obtained as described above has a rust removal effect on metal (15 sec to 30 m1n).
The liquid phase adheres to the strongly rust-removed metal surface, resulting in temporary rust prevention (rust removal treatment, no rust for 20 hours outdoors, 21 hours indoors). Smut residual treatment work associated with chemical rust removal (acidic rust removal), which is currently widely used as a rust removal method due to the two characteristics of the liquid phase, rust removal and rust prevention.
Pollution problems caused by acidic liquids will be solved.
