Small-Scale is a formula & ratios documented in the Chinese Practical Production Technology collection. The entry keeps the original material list, quantities and sequence, so you can follow the method as printed.

Is this an authentic Chinese method?

Yes. The underlying text is from mainland Chinese workshop literature aimed at small producers and home makers; the English on this page is a direct translation with the original numbers and steps preserved.

What do I need to get started?

The raw materials given in the formula, ordinary hand tools, and basic safety gear — gloves or eye protection depending on the step.

How long does it take?

The timing depends on your climate, batch size and equipment rather than on the text; the source records the process sequence rather than fixed hours, so follow the stages and check the material state at each one.

Can I run this as a small business?

Many entries in this collection were written with small-scale and home production in mind. Before selling, confirm the food-safety, labelling and local-registration rules that apply where you operate.

Is the full text available?

The complete English translation is in this article and is the same text used for the PDF download. Buying the PDF unlocks the full document without the preview cutoff.

New metal cleaning agentAdding surface-active substances to the cleaning agent can enhance the stability of the oil-water emulsion and improve the cleaning effect, but it is difficult to separate the oil from the clear liquid for recovery. In response to this problem, this article proposes a new metal cleaning agent formula that can separate oil from the cleaning fluid after use.The cleaning solution has the following components:A strong base (or alkaline component). Such substances include sodium hydroxide, potassium hydroxide, carbonate, silicate, borate and phosphate. It is better to use hydroxide of one or more groups among carbonate, phosphate, silicate and borate.A specially selected surfactant. This component must be a nonionic surfactant,HLBThe value is1~7.9, the molecule preferably contains two nitrogen atoms, and an organic amine (preferably ethylenediamine) containing two primary or secondary amine groups obtained by adding methyloxypropane and ethylene oxide in sequence, and the number of carbon atoms does not exceed22. and does not contain any other functional groups. In the formula, the weight ratio of surfactant to alkaline component generally ranges between1:100~1:5, the better range is1:50~1:10, the optimal range is1:26~1:12. The applicable r …
