How to solve the sulfur injection phenomenon in the mixing of Cable Sleeve

-

 Cable Sleeve mixing is the first process in the production of Stainless Steel Braided Sleeve, and the quality of the primary process also affects the subsequent processes of Stainless Steel Braided Sleeve. However, because the amount of sulfur in the rubber (partial rubber) exceeds its saturated solubility limit or supersaturated solubility limit at room temperature, the sulfur crystallizes out from the rubber. This phenomenon is called "sulfur injection phenomenon". So how to avoid this phenomenon? What is the reason for the "sulfur injection phenomenon"?

Pattern Wire Protective Sleeve

First of all, in order to avoid this phenomenon during production, manufacturers should usually pay attention to controlling the amount of sulfur in the rubber formula. In addition, partially insoluble sulfur may also be used instead of sulfur.
Secondly, the occurrence of "sulfur injection phenomenon" is generally caused by the following factors:
1. After the rubber is mixed, keep the temperature of the received materials, because the materials you receive during the stacking process will easily lead to high internal heat and accelerate the migration speed of the vulcanizing agent.
2. Because the temperature of the rubber compound is generally 95-110 degrees or even higher when vulcanizing, at this time the solubility of the rubber to the vulcanizing agent is high, and when the temperature decreases, the solubility decreases, so the vulcanizing agent will migrate outward.
In short, during production, the rubber material can be made into unvulcanized rubber material first according to the amount of glue produced, when to use it, and when to add vulcanization. Formulate corresponding specifications, first in first out, and specify the number of days for rubber storage, and confirm the performance after the number of days. Finally, the holding compound should be stored in a darkened room.

  Recently, the team from Chongqing Huifan Technology Co., Ltd.—a biometric technology enterprise operating under the international brand "HFSecurity"—arrived in Ghana immediately after attending the ID4Africa 2026 exhibition in Abidjan, Côte d'Ivoire. Without missing a beat, they embarked on a series of in-depth client visits and on-site project surveys, thereby fulfilling their market commitment to "take root in Africa and serve local communities" through concrete action. During their time in Ghana, the team visited numerous financial institutions, educational establishments, and partners involved in identity registration projects. At bank counters, real-name authentication terminals were operating with high efficiency; on university campuses, palm-vein recognition access gates were streamlining entry and exit management for students and faculty; and in remote regions, portable biometric data collection devices were shouldering the critical task of identity re...

The role of Neoprene Zipper Cable Sleeve in wire and cable

  Cables are mainly composed of three basic structural elements: a conductive core, an insulation layer and a sheath layer. It is mainly composed of three basic structural elements: conductive core, insulating layer and sheath layer. There is no strict boundary between wires and cables, but in a broad sense, cables have complex structures and complex sheaths, while wires have relatively simple structures. Some only have a conductor and an insulating layer, and some only have a waxed light protective layer or a light soft protective layer. The conductive core of the wire and cable is used to transmit electric current. In order to reduce power loss and voltage drop, the conductive wire core is generally made of copper and aluminum with high conductivity. The function of the insulating layer is to prevent the current from leaking in the radial direction and ensure the safety of use. Therefore, the insulating layer is required to have good electrical insulation properties. Heat resista...
