This paper introduces novel vacuum/compression valves (VCVs) utilizing paraffin wax. A VCV is implemented by sealing the venting channel/hole with wax plugs (for normally-closed valve), or to be sealed by wax (for normally-open valve), and is activated by localized heating

Questions

1–3 of 3 Questions  
  1. 76242 사용법 관련하여 몇가지 문의드립니다. Cu 시트 사이에 해당 파라핀왁스를 넣어 샘플을 제작하려고 합니다. 1. Pellets 형태로 제공된다고 나와 있는데, 이 왁스를 액체에 녹여 사용해야 하는지요? (혹시 필요한 첨가물이 있는지 궁금합니다.) 2. 또는 다른 첨가물 없이 온도만 높여 녹여서 사용 가능한지 궁금합니다. 3. 추가로, 녹는점이 약 40°C 정도 되는 파라핀왁스도 있나요? 답변부탁드리며 감사합니다.

    1 answer
    1. There is no information available on the use of this paraffin wax for the specific application of inserting it between copper sheets. The melting point for this material is 43-95 °C, and the transition temperature is 54-56 °C.

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  3. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
