QianGeWei Launches Dual-Density, Low-Residue Cotton Storage for Oil

QianGeWei Launches Dual-Density, Low-Residue Cotton Storage for Oil

The integrated oil storage cotton is a core component of electronic cigarettes. During the development of new products by complete machine manufacturers, it must prevent oil leakage without compromising the flavor, while also maintaining a low overall residual oil rate.

Addressing this perennial focus of technological innovation, the burgeoning market has prompted brands to increasingly emphasize research and development. As a pivotal player in the e-cigarette supply chain, the company QianGeWei has allocated significant resources, consistently investing no less than 15% of its annual revenue into R&D, aimed at pioneering new product directions. The launch of the dual-density, low-residual oil storage cotton marks a significant advancement; it not only ensures secure oil retention without leakage but also achieves a residue reduction of 30%-50% compared to existing products on the market.

烟油在储油棉中的传输情况

The transmission of e-liquid within the integrated cotton primarily comprises two components:

One portion moves downward, i.e., along the axis of the fibers, fundamentally relying on capillary action, and since synthetic fibers generally lack pores, transfer mainly occurs through the narrow gaps formed between fibers. Within a certain range, the greater the number of fibers per unit area, the stronger the capillary effect.
The other portion moves from the exterior inward, constituting nonlinear diffusion, wherein during the process of vaping, the e-liquid diffuses from the high-concentration integrated cotton to the lower-concentration wicking cotton.

虽然烟油成分相对复杂，但其主要成分PG/VG与水一样都是极性分子，因此用水作为类比具有一定的参考价值。一体式储油棉与烟油在相互的作用下，与水在纤维纺织中的传输情况相同。

Given the diversity in the structure and chemical composition of fibers within the fabric, their interaction with water molecules varies, leading to the absorption of water being categorized into three parts: bound water, intermediate water, and free water, as depicted below.

Similarly, upon absorbing e-liquid, the integrated cotton wick will also form bound oil, intermediate oil, and free oil.

During the vaporization process of electronic cigarettes, if certain constituents of the e-liquid form exceedingly tight "bound oil" and "intermediate oil" through hydrogen bonds or intermolecular forces with the fibers, it results in impaired e-liquid delivery, leading to issues of high residue and low fidelity.

为了解决上述问题，深圳千格维从材质选择，生产工艺升级以及成分配比进行了全方位多方向的综合优化，历经半年的研发，推出行业独创（渐变棉）一棉双芯（聚油芯）颠覆性技术，完美的解决了烟油大量剩余，锁油性能的不稳定及导油效果不理想的问题。
