CRF防鏽鏈條

| 關於CRF防鏽塗層

碳鋼鏈條具有良好的強度以及耐磨性，但不適合在腐蝕環境使用為其缺點；不鏽鋼鏈條雖然有優異的耐腐蝕性能，但強度以及耐磨性常不能符合客戶需求。

MCC CRF鏈條是以碳鋼鏈條為基礎，加上CRF防鏽塗層處理，達到良好的防鏽性能，而強度只比碳鋼鏈條略低一些。

CRF防鏽塗層是由鋅、鋁薄片以及無機黏著劑組成，具有銀金屬般的外觀。

 

| 特色

1.無汙染，實現對環境的責任

  • 水性化學溶液：CRF屬於水性塗料，由於塗料不是溶劑型，處理過程不會有揮發性有機物影響環境及作業人員健康。
  • 完全不含鉻及其他有毒金屬：CRF塗料的加工及防銹層本身完全不使用鉻化合物(一種致癌物質)。
  • 不含有毒金屬：不含鎳，鎘，鉛，鋇和汞等有毒金屬，符合RoHS、ELV、REACH法規的要求。
  • 封閉系統塗裝方法：CRF塗料的加工是一種沒有汙水排放的封閉系統，塗裝烘烤製程的主要排放物是水蒸氣，且不含任何法令管制的有毒物質。

2.沒有氫脆化疑慮：CRF原料及塗裝過程沒有接觸產生氫脆的物質，不會因氫脆化產生危險。

3.良好的耐高低溫能力：在鏈條耐溫範圍(-30℃~250℃)都無損其防鏽能力

  • 因為鏈條材質的物理限制，在低於-10℃以及高於150℃的環境，鏈條可容許負荷會有下降。

 

4.優異的防銹能力，鹽水噴霧試驗可達600hrs以上

 

| About CRF Corrosion Resistant Roller Chain

MAXTOP CRF corrosion resistant chains have excellent performance in corrosive environments.
CRF chain is based on carbon steel chain with CRF coating treatment to achieve good anti-rust performance.
The coating film has silver metallic look. Layers of metallic silver film are aligned with one another through the use of a binder, zinc and aluminum flakes.

| Features

1.No harm to the environment and health

  • Water-based chemical solution: Using aqueous liquid, the coating is not solvent-base; the surface treatment is friendly to both natural and working environments.
  • Completely chromium-free: Chromium compound is not used in the processing for CRF coating.
  • No Toxic Metal – Free of nickel, cadmium, lead, barium and mercury. It completely meets the requirement of RoHS, ELV and REACH regulations.
  • Closed system coating process: CRF coating is environmentally friendly; the main waste disposal of this coating is the steam and do not include any toxic substances regulated by law.

2.No concern for hydrogen embrittlement

CRF coating film and the coating process are not in contact with substances that could cause hydrogen embrittlement. 

3.Superb resistance to high and low temperature

CRF film is able to withstand high and low temperatures for an extended period of time – within the temperature range of the chains from -30°C ~ 250°C(-22°F ~ 482°F).
  • The allowable load may decrease when the temperature is below -10°C or above 150°C depend on the chain sizes.

4.600 hours corrosion protection during salt spray test 

CRF coating provides an outstanding corrosion resistance during the salt spray test (the test is based on ASTM B117 testing standard). Below is the test result after 600 hours salt spray test.
