What material is APS and what material is APS

APS is ammonium persulfate.

ammonium persulphate), also known as ammonium disulfite.

It is an ammonium salt.

Main ingredient: Industrial grade content 95%.

Appearance and properties: colorless monoclinic crystal, sometimes slightly light green, deliquescent.

It is an ammonium salt of perdisulfate. Perdisulfate contains peroxide groups and is a strong oxidizing agent. At 120 hours, oxygen is released and pyrosulfate is generated. Ammonium perdisulfate is a strong oxidizing agent. Ammonium disulfite can be prepared by electrolysis of ammonium bisulfate in aqueous solution.

Melting point ( ) 120 (decomposition).

Boiling point ( ) decomposition.

Ammonium persulfate. Ammonium persulfate (Ammonium persulphate), also known as ammonium persulfate, is an ammonium salt with the chemical formula (NH4) 2S2O8 and a molecular weight.

Studies have shown that ammonium persulfate is widely used in the battery industry as an oxidizing agent and bleaching agent; It is also used as an initiator for polymerization, a desizing agent in the fiber industry; It can also be used as a surface treatment agent for metal and semiconductor materials, and an etching agent for printed circuits; It is also widely used in oil layer fracturing for oil extraction, flour and starch processing industry, oil and fat industry, and used to remove sea waves in the photographic industry.

Ammonium persulfate (APS) is a traditional oxidizing agent.

I know that ABS is a material used in plastic products and is occasionally used in automaton molds. APS is a 2D programming software in Taiwan that can also make simple 3D programs.

Hope it helps.

In order to facilitate our daily use and take into account our human memory ability, we often refer to the very responsible things as abbreviations, often replaced by a few letters, although it looks simple, but in fact there is a big connotation, today let's learn what APS is.

APS is ammonium persulfate (ammonium persulphate), also known as ammonium persulfate, is an ammonium salt with the chemical formula (NH4) 2S2O8 and a molecular weight.

Studies have shown that ammonium persulfate is widely used in the battery industry as an oxidizing agent and bleaching agent; It is also used as an initiator for polymerization, a desizing agent in the fiber industry; It can also be used as a surface treatment agent for metal and semiconductor materials, and an etching agent for printed circuits; It is also widely used in oil layer fracturing for oil extraction, flour and starch processing industry, oil and fat industry, and used to remove sea waves in the photographic industry.

APS Main Purpose:

1. Verification and determination of manganese as an oxidant. Bleacher. Photographic reducing agents and blockers. Battery depolarizer. It is used in the preparation of soluble starch.

2. It is used as an initiator for the polymerization of ethylene monomer emulsions such as vinyl acetate and acrylates, which is cheap and has good water resistance. It is also used as a curing agent for urea-formaldehyde resin, with the fastest curing speed. It is also used as a co-oxidant for starch adhesives, and reacts with proteins in starch components to improve adhesion, and the reference dosage is starch.

It is also used as a surface treatment agent for metal copper.

3. It is used in the chemical industry as a raw material for the manufacture of persulfate and hydrogen peroxide, a polymerization copolymer for the polymerization of organic polymers, and an initiator for the polymerization of vinyl chloride monomer. It is used as a bleach agent in the oil and soap industry. It is also used as a corrosive agent during metal plate erosion and oil recovery in the petroleum industry.

Food grade is used as wheat modifier and brewer's yeast antifungal agent.

Founded in July 2001, the Cultural Affairs Department of the German Embassy in China (APS) is a joint venture between the Cultural Office of the German Embassy in China and the German Academic Exchange Service (DAAD) in Beijing.

APS is the gateway for Chinese students to study in Germany, and its main responsibility is to check the qualifications of Chinese students (excluding academic qualifications from Hong Kong, Macau and Taiwan) who are interested in studying in Germany.

Applicants applying to study in Germany can submit their visa application through APS after obtaining an APS certificate and a letter of acceptance from a German university.

Introduction: Founded in July 2001, the German Embassy in China (APS) is a service organization jointly established by the Cultural Office of the German Embassy in China and the German Academic Exchange Service (DAAD) in Beijing.

The Audit Department is the gateway for students to study in Germany. When the applicant passes the document review and participates in the audit interview or testas test, he or she can obtain an audit certificate, which is one of the prerequisites for German universities to admit Chinese students. Possession of a certificate indicates that the application materials submitted by the applicant are genuine and that he or she has achieved sufficient academic results at a Chinese university to apply for a German university.

Please note that the Audit Department does not review academic qualifications from Hong Kong, Macau and Taiwan.

The Audit Department has also been working with Austria (since the beginning of 2005) and Belgium (since the end of 2006). Applicants applying to study in Austria and Belgium are also subject to an interview by the Audit Department.

Applicants who apply to study in Germany can submit their visa application through the Examination Department after obtaining a certificate from the Audit Department and an acceptance letter from a German university. Applicants applying to study at universities in Austria and Belgium need to submit their visa applications directly to the relevant embassy.
