Reduce the Generation and Transmission of Vibrations<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, PK materials have a high damping effect due to their relatively low glass transition temperature (approximately 10\u00b0C).&nbsp;They can absorb and attenuate vibration energy during gear meshing, reducing noise from the source.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In fan noise tests, PK+GF showed a noise level 5 dB lower than traditional PA66+GF\/MF, creating a quieter environment.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"692\" height=\"419\" src=\"http:\/\/tempsite02.honeitech.com\/wp-content\/uploads\/image-76.png\" alt=\"\" class=\"wp-image-1341\" srcset=\"https:\/\/www.wdfsz.com\/wp-content\/uploads\/image-76.png 692w, https:\/\/www.wdfsz.com\/wp-content\/uploads\/image-76-300x182.png 300w\" sizes=\"(max-width: 692px) 100vw, 692px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"692\" height=\"412\" src=\"http:\/\/tempsite02.honeitech.com\/wp-content\/uploads\/image-77.png\" alt=\"\" class=\"wp-image-1342\" srcset=\"https:\/\/www.wdfsz.com\/wp-content\/uploads\/image-77.png 692w, https:\/\/www.wdfsz.com\/wp-content\/uploads\/image-77-300x179.png 300w\" sizes=\"(max-width: 692px) 100vw, 692px\" \/><\/figure>\n\n\n\n<p class=\"has-vivid-cyan-blue-color has-text-color has-link-color has-medium-font-size wp-elements-5 wp-block-paragraph\"><strong>2<\/strong><strong>. <\/strong><strong>Prevent Vibrations from Being Continuously Amplified<\/strong><strong><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many devices can operate quietly at the beginning, but the real difference lies in:&nbsp;How long can this condition be maintained?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During continuous rotation, gears also need to withstand:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00b7 Repeated start and stop cycles;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00b7 Load changes;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00b7 Humid environments or temperature differences.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the gear material is not selected appropriately, over time, material wear will increase or dimensions will change.&nbsp;The gear clearance will then change, amplifying vibrations and transforming them into more noticeable noise.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"has-text-align-center has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-6 wp-block-paragraph\"><strong>\u25bc<\/strong><\/p>\n\n\n\n<p class=\"has-text-align-center has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-7 wp-block-paragraph\"><strong>A Good Experience Also Means Less Disturbance<\/strong><\/p>\n\n\n\n<p class=\"has-text-align-center has-text-color has-link-color has-small-font-size wp-elements-8 wp-block-paragraph\" style=\"color:#496e8f\">The noise generated by products is often not \u201cunusable\u201d,<\/p>\n\n\n\n<p class=\"has-text-align-center has-text-color has-link-color has-small-font-size wp-elements-9 wp-block-paragraph\" style=\"color:#496e8f\">but rather \u201ccontinuous disturbance\u201d.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During long-term use, the differences caused by materials in these invisible components cannot be directly perceived, but they gradually reveal themselves through every operation.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"692\" height=\"389\" src=\"http:\/\/tempsite02.honeitech.com\/wp-content\/uploads\/image-78.png\" alt=\"\" class=\"wp-image-1343\" srcset=\"https:\/\/www.wdfsz.com\/wp-content\/uploads\/image-78.png 692w, https:\/\/www.wdfsz.com\/wp-content\/uploads\/image-78-300x169.png 300w\" sizes=\"(max-width: 692px) 100vw, 692px\" \/><\/figure>\n\n\n\n<p class=\"has-vivid-cyan-blue-color has-text-color has-link-color has-medium-font-size wp-elements-10 wp-block-paragraph\"><strong>\u25cf&nbsp;&nbsp;<\/strong><strong>Finally, Let\u2019s Take a Look at What Advantages PK Materials Can Provide in Gear Systems:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1. Ensure Stable Operation: Resistant to Humidity and Chemical Environments<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Low Water Absorption:<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The ater absorption of PK is approximately 0.5%, which is much lower than PA66.<\/p>\n\n\n\n<p class=\"has-cyan-bluish-gray-color has-text-color has-link-color wp-elements-11 wp-block-paragraph\">This means that gears will not experience jamming or changes in transmission clearance caused by water absorption and expansion in humid environments or during long-term operation, demonstrating excellent dimensional stability.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Excellent Chemical Resistance:<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">PK has strong resistance to acids, alkalis, solvents, and other chemicals, second only to PPS.<\/p>\n\n\n\n<p class=\"has-cyan-bluish-gray-color has-text-color has-link-color wp-elements-12 wp-block-paragraph\">In daily use, even when exposed to cleaning agents or oil contamination, the material is not easily corroded or degraded, ensuring the long service life of gears.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2. Provide a Comfortable and Quiet Environment: Wear Resistance and Noise Reduction<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Excellent Wear Resistance\uff1a<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">PK materials have a low coefficient of friction, and their wear resistance is approximately 14 times that of POM.<\/p>\n\n\n\n<p class=\"has-cyan-bluish-gray-color has-text-color has-link-color wp-elements-13 wp-block-paragraph\">During long-term operation, they experience less wear and are less likely to suffer performance degradation or failure.<\/p>\n\n\n\n<p class=\"has-cyan-bluish-gray-color has-text-color has-link-color wp-elements-14 wp-block-paragraph\">This helps extend gear service life and reduce maintenance and replacement frequency.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Noise Reduction Effect\uff1a<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Operation becomes quieter and smoother.<\/p>\n\n\n\n<p class=\"has-cyan-bluish-gray-color has-text-color has-link-color wp-elements-15 wp-block-paragraph\">It effectively reduces noise and vibration caused by friction, making operation more stable and quiet, significantly improving overall user comfort.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>",
