Thread coating

The stems of wax matches consists of a wick of twisted cotton threads, coated with wax, or more generally with mixtures of stearin, paraffin, and gum dammar or gum opal. These matches burn for a longer time than matches made from wood. 

The bottom of the pipe is secured by screwing the cap on over threads coated with Teflon tape. Welding may also be used. The pipe is then nestled into a Styrofoam cooler, and is then filled about Vi full of rubbing alcohol, and then to this solvent dry ice is added, slowly at first to prevent it from boiling over, then more rapidly. The top of the pipe should be covered to prevent frost from forming inside the pipe as it cools down.

One of the advantages of using CHT for obtaining various medicinal materials- ms, threads, coatings, gels, is its capacity for enzymatic destmction under the action of enzymes of a living organism [1]. 

Figure 7.16 SEM of a monofilament of poly (p-dioxanone) loaded with ibuprofen exposed for 24 h to a dichloromethane bath with a drug concentration of 10% (a) and a braided polyglycolide thread coated from an ethyl acetate bath containing 3% of PLA/PCA/PTMC 10/60/30 and 1% of ibuprofen (b). Insets correspond to higher magnifications that reveal the presence of some particles and striations (see arrows) on the surface of poly (p-dioxanone), and the coating on the polyglycolid threads (see arrows) [145]...

Dry Lubricant. The static and dynamic coefficients of friction for the parylenes are low and virtually the same. This feature is an advantage in the use of a parylene coating as a dry lubricant on the bearing surfaces of miniature stepping motors. Coating a threaded ferrite core significantly reduces the abrasion to coil forms (82).

Different resins have been developed for use in different reduction—ratio appHcation ranges (111,112). The powders suitable for high reduction—ratio appHcations, such as wire coatings, are not necessarily suitable for the medium reduction—ratio appHcations, such as tubings, or the low reduction—ratio appHcations, such as thread-sealant tapes or pipe liners. AppHcations and processing techniques are being used, which utilize the unique combination of properties offered by PTFE in fine powder form (113—115). 

Articles of circular cross section may be made in iron paste molds. To keep the inner surface of the paste mold moist, it is coated with shellac or varnish and a mixture of charcoal and linseed oil is baked on. Hot iron molds ate used for ware of any shape, particularly for screw threading, multiple decoration, or raised lettering. 

Traditional appHcations for latices are adhesives, binders for fibers and particulate matter, protective and decorative coatings (qv), dipped goods, foam, paper coatings, backings for carpet and upholstery, modifiers for bitumens and concrete, and thread and textile modifiers. More recent appHcations include biomedical appHcations as protein immobilizers, visual detectors in immunoassays (qv), as release agents, in electronic appHcations as photoresists for circuit boards, in batteries (qv), conductive paint, copy machines, and as key components in molecular electronic devices. 

Silk (qv) suture is made from the threads spun by the silkworm Bombjx mori. The fiber is composed principally of the protein fibroin and has a natural coating composed of sericin gum. The gum is usually removed before braiding the silk yams to make sutures in a range of sizes. Fine silk sutures may be made by simply twisting the gum-coated silk yams to produce the desired diameter. White silk is undyed. Silk is either dyed black with logwood extract or blue with D C Blue No. 9. The suture may be uncoated or coated either with high molecular weight polydimethylsiloxane or with wax.

The fasteners contacted sheets of stainless steel. Threaded regions of the fasteners that were exposed to water were severely wasted. Threaded regions that were not exposed remained intact. Some exposed fastener surfaces were coated with plastic. These areas were also unaffected.
