Definitions
- plastic containers such as bottles, balloon bottles, wide-mouth bottles, wash bottles, canisters etc. for storing liquid chemical substances such as e.g. inorganic and organic solvents are widely used.
- plastic containers which mostly consist of polyethylene or polypropylene, have the advantage in daily use in the chemical laboratory that they are lightweight, unbreakable, elastic and also particularly inexpensive.
- plastic containers made of PE or PP or other similar hydrogen-containing polymers have the disadvantage that they do not have the required or desirable long-term resistance to diffusion compared to many aggressive, mainly organic solvents such as aliphatic or aromatic hydrocarbons or halogenated hydrocarbons or ketones, aldehydes and strong oxidizing agents, Have swelling or extraction of substances from the containers.
- containers made of glass, metal or Teflon can be used to store such aggressive solvents, but this is associated with disadvantages such as fragility (with glass), higher weight and higher costs.
- PTFE glass, metal or Teflon
- PFA Teflon
- containers made of glass, metal or Teflon can be used to store such aggressive solvents, but this is associated with disadvantages such as fragility (with glass), higher weight and higher costs.
- a procedure has been developed in laboratory article practice in which the inner surfaces of the surfaces which are in contact with the solvents hydrogen-containing plastic containers made of PE or PP are treated by fluoridation, at least some of the near-surface hydrogen atoms being substituted by fluorine atoms (for example containers made of PE with a partially fluoridated surface from Nalgene).
- fluorine atoms for example containers made of PE with a partially fluoridated surface from Nalgene
- Liquid light guides are also known which are made of a Teflon®
- Hose exist, the inner surface of which is coated with an amorphous perfluoropolymer to improve total reflection (DE 42 33 087 A1).
- Post-treat PE or PP with a partially fluorinated inner surface in the sense that a perfluorinated inner skin or layer is created which has the optimal and desirable chemical resistance. It has been shown that amorphous perfluorinated fluoropolymers adhere particularly well to a partially fluorinated surface made of PE or PP if thin layers of these perfluorinated amorphous materials are produced from solution by simply wetting the surface with the solution and then evaporating off the solvent. In this way, layers of several ⁇ thickness can be produced. If the surfaces of the PE or PP containers are not fluoridated beforehand, the layers of perfluorinated amorphous fluoropolymers do not adhere, or much worse.
- containers or tubes for use in the chemical laboratory are also made from other polyhydrocarbons, the surfaces of which can also be partially fluoridated and thus form a good basis for adhesion for coating with amorphous perfluoropolymers from the liquid phase.
- Such materials are:
- Hose made of polyhydrocarbons, in particular PE or PP, the inner surface of which has been fluoridated.
- Teflon® AF from DuPont, which is a copolymer of tetrafluoroethylene with perfluoro-2,2-dimethyl-1,3-dioxol, or an amorphous perfluoropolymer from Ausimont, Hfylon® AD, a copolymer of tetrafluoroethylene with another special dioxol, namely 2.2 , 4-trifluoro-5-trifluoromethoxy-1,3-dioxole, as described in EPO 803 557 A1 or EPO 633 257, or
- Teflon® SF a copolymer of tetrafluoroethylene with hexafluoropropylene (TFE / HFP) or perfluorovinylmethyl ether (TFE / PMVE), the amount of monomer copolymerized to TFE being unusually high, i.e. is in the range of 20-40 percent by weight. These are amorphous perfluoroelastomers. Such copolymers are described in EP 0656 912 B1.
- a liquid, high-boiling (column 270 ° C) and highly viscous perfluoropolyether e.g. Fomblin® or Galden® from Ausimont
- the weight fraction of the perfluoropolyether in the layer can be up to 30% (see also WO 98/38538).
- the perfluorinated protective layers inside the plastic containers or tubes with partially fluorinated inner surface can be produced by partially filling these containers with the liquid solution of the amorphous fluoropolymer, then subjecting this container to a swiveling or tumbling movement so that its entire inner surface is uniformly wetted, and while maintaining the tumbling movement of the container, possibly with the aid of a warm air stream, ensures that the solvent, for example FC 75, evaporates as completely as possible. After completing this process, a uniformly thick layer of a few ⁇ is observed on the inner surface of the
- Heating the open container to a temperature above the boiling point of the solvent ensures complete evaporation of the solvent while improving the
- Adhesion of the layer to the base Further heating up to above the glass transition temperature of the amorphous fluoropolymer is recommended to achieve a closed and well-adhering, dense film made of the amorphous material. In the case of DuPont material Teflon® AF, this temperature is in the case of DuPont material Teflon® AF.
- Ausimont material has an increased solubility in the perfluorinated liquids (FC 75) compared to Teflon® AF, so that even thicker layers can be achieved that are close to 10 ⁇ or even more than what Teflon® AF can only be achieved with great effort.
