密胺餐具属于High molecular weightPolymer的英文缩写是MFThe monomer of it is formaldehyde andmelamineReaction time is 37%.Formaldehyde solutionFormaldehyde and MelamineMoleFor 2 to 3.

Research indicates that as the amount of formaldehyde increases, so does the amount of formaldehyde binding, making the reaction relatively easy to conduct. By altering the amount of formaldehyde, it is possible to prepare melamine resin derived from different hydroxymethyl groups, with fewer side reactions occurring in the reaction system at pH 8.5, making the reaction easier to control. High temperatures lead to rapid reaction rates, and within the range of 54 to 80 degrees Celsius, there is little impact on the amount of formaldehyde binding.

The first step in the reaction is to generate different numbers of N-hydroxymethyl substitutes, and then further condense into linear resins. Generally, the molecular weight of the product varies depending on the reaction conditions, ranging from soluble in water to insoluble in water, and even to insoluble and non-meltable solids.Mina resinUnder room temperature, it does not cure, and generally needs to be heated cured at 130~150℃. Research shows: adding a small amount of acid during curing as aCatalystCan improve the curing rate. The cured melamine-formaldehyde resin is colorless and transparent, stable in boiling water, and can even be used at high temperatures of 150°C. It has self-extinguishing, anti-arcing, and good mechanical properties.

Ingredients

Mina粉It is made from melamine formaldehyde resin.celluloseIt is composed of a base material, along with pigment and other additives, and is therefore three-dimensional.Reticular structureTherefore, it belongs tothermosettingIngredients: (Waste edges cannot be recycled for production). The scientific name of Melamine Powder is Melamine-Formaldehyde Resin, abbreviated as "MF"...[1]

A1 material (not suitable for tableware)

(Contains 30% of melamine resin, with the remaining 70% consisting of additives, starch, etc.)

Features: Although it contains melamine, it still has plastic characteristics. It is toxic, not heat-resistant, not stain-resistant, not corrosion-resistant, has a rough appearance, is prone to deformation and color change, and has poor shine.

A3 material (not suitable for tableware)

Contains 70% of melamine resin, with an additional 30% composition of Additiveand淀粉and so on,

Features: The appearance is almost identical to the genuine product (A5 material), but onceUseThe product is not durable, easily becomes dirty, discolors, fades, and is prone to deformation at high temperatures. It is also not resistant to corrosion.

A5 material can be used for melamine tableware (100% melamine resin)

Features: non-toxic and odorless, temperature resistance from -30°C to 120°C, resistant to impact, corrosion, not only has a beautiful appearance, but also is light and insulating, safe to use.

A8 material, tableware characteristics

The characteristics are as follows:

1. Melamine-formaldehyde molding powder is odorless, tasteless, and non-toxic.

2. Melamine-formaldehyde plastic has a high surface hardness, shine, and is resistant to scratching.
