In the process of using the vacuum packaging machine will encounter the following common problems: 1. Low vacuum 2. Noise 3. Vacuum pump injection 4. Vacuum pump leakage 5. Vacuum pump soot 6. No heating 7. Heating is not Stop 8. Sealing is not smooth, tight or not sealed steel box deformation adjustment steel box 9. While heating, while not heating 10. Pump does not pump vacuum 11. Cover does not work, etc. 1. Pump oil pollution, too little or too lean cleaning vacuum pump, replace the new vacuum pump oil; pumping time is too short to extend the pumping time; suction filter plug cleaning or replacement exhaust filter; leak, close after emptying Power supply, check the solenoid valve, pipe fittings, vacuum pump suction valve and the surrounding area of ​​the studio gasket for leaks. 2. The vacuum pump coupling wears or breaks; the exhaust filter is clogged or the installation position is not correct. Clean or replace the exhaust filter and install it correctly. If there is a leak, check the solenoid valve for leaks and remove it. Vacuum packaging machine (1 sheet) 3, the suction valve O-ring off the vacuum tube on the pump nozzle, remove the suction nozzle, remove the pressure spring and suction valve, gently stretch the O-ring several times, re-embedded in the groove, and then Can be installed; rotary vane wear replacement rotary vane. 4. The oil return valve is blocked to remove the oil return valve and cleaned (see the instructions for details). After the oil window is loosened and drained, remove the oil window and wrap the raw material tape or thin plastic film. 5, suction filter plugged or polluted cleaning or replacement of exhaust filter; pump oil pollution replaces new oil; return valve block plug cleaning return valve 6. Heat bar burned to replace the heating bar; heating time relay burned out (two lights on at the same time, bright, OMRON lamp color is yellow), replace the time relay; replace the heater wire with the heating wire, and install firmly; control the heating temperature band Poor contact of the switch, repair or replacement; control of the heated AC contactor does not reset the repair (using a gas flow to blow off foreign objects) or replacement; the bad replacement of the heating transformer 7. When the heating time relay is in poor contact or burnout, adjust the time relay to contact or replace the socket; control the heating AC contactor to not reset or replace. 8, heating time and heating temperature is not adjusted to adjust to the right; there are attachments on the heated cloth with a nail to gently scrape attachments; pressure solenoid valve does not act to clean or replace the solenoid valve; airbag damage replacement airbag; pressure tube damage Repair or replace; no bleed cooling time relay is bad (in the electrical box) replacement time relay; deflate valve circuit is open circuit to find and connect; deflate valve is stuck or burned to remove cleaning or replacement 9. Non-heating side of the packaging bag and the heating device short-circuit (usually short circuit with the brazing sheet) Adjust the position of the brazing sheet, or rest the bag pouches 10. The studio does not cover the studio tightly; the motor is reversed (be careful not to change the ground wire, the color line is the ground wire); the insurance disconnect (indicator light is on) replace the same specifications insurance 11, no power to check whether the power supply; trip switch does not act to adjust the trip switch paddle; insurance off (lights on the indicator) Replace the same specifications insurance frequently burn insurance short circuit to find and rule out; motor reversal time is too long any two-phase power cord Replacement installation (except ground); oil viscosity is too high Clean the pump and replace the oil inside the fuse box More vacuum pump information is available at China Vacuum Pump Trading Network (/).
Boron Triiodide AKA Boron Iodide is a chemical compound of Boron Product and iodine with chemical formula BI3. Iodide Boron has a trigonal planar molecular geometry. It is a crystalline solid, which reacts vigorously with water to form hydroiodic acid and boric acid.Its dielectric constant is 5.38 and its heat of vaporization is 40.5 kJ/mol. At extremely high pressures, BI3 becomes metallic at ~23 GPa and is a superconductor above ~27 GPa.
Triiodide Boron is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Iodide compounds are used in internal medicine. Treating an iodide with manganese dioxide and sulfuric acid sublimes the iodine. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Melamine Powder Pharmaceutical Grade; Optical Grade Boric Acid Flakes, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical Boron Triiodide Powder and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
