| UPS Driver Literally Drops Package with New Hana Umami Red Not to escape the obvious, but was this near $4K cartridge not shipped with signature-required? | |
| The "Very Best Record Cleaning Formulation" @wizzzard, The discourse with using Hansen solubility parameters is not unknown - Hansen solubility parameter - Wikipedia. My use of it within this forum was only as a prediction. If your feelings on this subject are so intense, you have a poss... | |
| The "Very Best Record Cleaning Formulation" @kylehildebrant . My reference for a concern was an open top UT tank with 6000-ml and larger volume. Your HG contains 350-ml in a mostly closed tank. Ask the manufacturer who is very responsive to requests what they think. Beyond flammability th... | |
| The "Very Best Record Cleaning Formulation" @wizzzard, You can say what you wish, but the law (29 CFR 1910.106) is very specific as to what is classified as flammable - NFPA_30_Fact_Sheet_2021.ashx. And, in larger volumes, in small spaces, flammable vapors can be build up - NFPA Journal - ... | |
| The "Very Best Record Cleaning Formulation" @lewm, The KL Audio is 40kHz, with four 50W horizontally positioned transducers, two each side (200W total) with a UT tank volume of only about 0.78L - that is it's a very powerful machine. Note that the reservoir is 2.4L, but someone recently m... | |
| The "Very Best Record Cleaning Formulation" 1,1,2-Trichlorotrifluoroethane is also officially identified as CFC-113 by the EPA such as Ozone-Depleting Substances | US EPA, by ASHRAE STD -34, Designation and Safety Classification of Refrigerants, and by CDC such as Preventing Death from Exce... | |
| The "Very Best Record Cleaning Formulation" @mijostyn, RE: Is there any data on the extraction of ESO by Chlorofluorocarbons? Granted it is only 1% of the formulation but wouldn't extraction of ESO actually harden the PVC? Not that I am aware of. The Navy in 1994 reported testing of N... | |
| The "Very Best Record Cleaning Formulation" @lewm, In polymer science there is an entire field of study surrounding the Hansen Solubility Parameters with a brief introduction here: Mechanical Properties of Polymer Nanocomposites (turi.org). There is a large handbook available to purchas... | |
| The "Very Best Record Cleaning Formulation" Figure 39 – Water + Alcohol Surface Tensions of at 25°C from PACVR (adapted with permission copyright 1995, American Chemical Society) Data for Figure 39 is from “Surface Tension of Alcohol + Water from 20 to 50°C”, Gonzalo Vazquez, Estrella ... | |
| The "Very Best Record Cleaning Formulation" In the interest of accuracy, in my last post I stated - " The formula provided by @wizzzard is by weight 22% ethanol and 0.038% Tergitol 15-S-7 which ~380 ppm which is 10 x CMC." I made an error, the concentration of Tergitol 15-S-7 is 38 mg, and... | |
| The "Very Best Record Cleaning Formulation" @pindac, @whart, and any others reading, Thank-you for the kind words. Keep in-mind that what I present is a process - not a single chemistry. My aqueous process is centered around pre-clean, rinse, final-clean, rinse and is the industry stand... | |
| The "Very Best Record Cleaning Formulation" @mijostyn, If you ever took the time to read the book you would find a multitude of methods, beyond the in-expensive manual process; not everyone has your wealth. Also, its rather inexpensive to filter US tanks to 0.2-micron absolute keeping the ... | |
| The "Very Best Record Cleaning Formulation" @wizzzard, If you carefully read @drkingfish he mentioned ’us’ that is a common abbreviation for ultrasonic (tank). Otherwise, here a phase diagram for ethanol-water - Ethanol-Phase-Diagram.jpg (800×695) (moonshinedistiller.com) and distillation... | |
| The "Very Best Record Cleaning Formulation" @wizzzard, To the contrary - I know exactly what I am saying. I am the author of this book - Precision Aqueous Cleaning of Vinyl Records-3rd Edition - The Vinyl Press with over 20-yrs experience in developing precision cleaning processes for sh... | |
| The "Very Best Record Cleaning Formulation" @drkingfish WARNING: 22% Ethanol is flammable with a flashpoint of about 75F. Using this concentration in an Ultrasonic Tank with 100’s or 1000’s of mL that is not explosion proof rated is dangerous. With an ultrasonic unit three mechanisms ar... |
