144245-85-2 factory /Alkylketene dimer in China

Product name: Alkylketene dimer  AKD Emulsion (LS-A10/15/20)

Synonyms: Alkyl Ketene Dimer Emulsion

Product features:

The stability of Alkylketene dimer emulsion with high solid content and high efficiency is increasing continuously. At the same time, the sizing rate increases to 90%.Thus this new Alkylketene dimer is suitable to the development of slight coating and high-speed paper machine.

Functions:

Alkylketene dimer  neutral sizing agent solves the problems such as yellowing, brittleness and so on, which were caused by acidic sizing. At the same time, it can improve paper whiteness, smoothness and physical strength. And Alkylketene dimer can also remarkably improve the printing suitability and inkabsorptivity of the paper, thus fitting the development of inking technology. Meanwhile, it can reduce the load of white water, and energy consumption, improve the operational environment.

Usage method:

Alkylketene dimer can be directly add to the thick pulp, or add to the mixing chest after diluted. And

it can also be tub-sized after the former paper dried. The added amount should be 0.1%-0.2% of absolute dry pulp for normal sizing, 0.3%-0.4% for heavy sizing. Double resident system of cation starch and polyacrylamide should be coupled with at the same time. The cation starch should be quaternary ammonium type, its substitute degree is more than

0.025% and its usage should be 0.6%-1.2% of absolute dry pulp. The molecular weight of polyacrylamide is 3,000,000-5,000,000, its concentration is 0.05%-0.1% and its usage should be100ppm-300ppm. The PH of pulp is 8.0-8.5.

Applications:

Alkylketene dimer emulsion is one of the reactive neutral sizing agents, Alkylketene dimer can be used in the process of neutral paper making in factories directly. Paper can not only be endowed with predominant capability of water resistance, and soak capability of acid alkaline liquor, but also with ability of brim soaking resistance. By using it can improve physical properties of paper, it has been widely used in producing various kind of paper, such as art base paper, electrostatic autographic transfer paper, double colloid paper, noncarbon paper, archival paper, photo base paper, yew base paper, stamp base paper, napkin, etc.

Notice:

If the phenomena as the separation, thickening or large amount of gas given off of Alkylketene dimer emulsion are found before use, the usage of Alkylketene dimer should be stopped immediately. In high temperature of summer, 30ppm-50ppm of germicide can be added to the pulp pool or white water.

Tianma’s core mind and policies is we should protect the security of customers’ intelligent property.

1  All IP developed as a service by Tianma’s chemists, under a customer CDA or MSA, is the property of the customer.  Under customer CDA or MSA, all of the Tianma Chemists’ IP development service is belong to customers.

2  Duty of confidentiality has been written in employment contract. And every employee should agree and sign it.

3  Customer and Tianma’s IP are protected by both side’s national law and company agreements.

Electronic security access and information dissemination are controlled strictly.

1  Secure VPN tunnels for email transfers confidential info to customers.

2  Tianma Central Document Server (CDS) which can assigned security access, control the access of project specific information.

3  Notebooks, MOR’s and others are collected in archived room and be monitored under strict access.

4  Only the basic information( need to know level) of the project details shared by related working group.

Tianma has additional proactive employee training which emphasize about the law and risk of persecution and conviction:

1  Regular retraining of Tianma staff on IP protection and need for security.

2  Inviting local police to introduce the latest criminal convictions of IP theft in China.

3  Explanation of China Patent Law and customer CDA‘s.
