Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd., a professional manufacturer of pharmaceutical packaging materials testing equipment, has provided research and exchanges and internships for researchers, research institutes and large and medium-sized enterprises. It should be tested by universities and research institutes. The laboratory has requested the development of several testing instruments for the detection of adhesive products. They are: 180° peel strength tester BLJ-C, initial tack tester CNY-1, holding adhesive tester CNY-2A, adhesive tape Roller YGJ-S. The following small series will detail the application of these devices in the laboratory. Pharmacy is a high-level science that cultivates basic theories, basic knowledge and experimental skills of pharmacy, and can work in the fields of drug production, testing, circulation, use and research and development in the fields of identification, drug design, general pharmaceutical preparations and clinical rational drug use. The discipline of technical talent. In order to meet the needs of pharmaceutical laboratory for the detection of adhesives, Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. has developed a number of testing equipment to boost the development of China's medical industry. College and university laboratory adhesives initial tack tester First, the initial viscosity tester for adhesive products in colleges and universities; The initial tack tester CNY-1 uses the bevel ball method to test the initial tack of the test specimen by using the adhesion of the product to the steel ball when the steel ball and the adhesive surface of the test specimen are briefly contacted by a slight pressure. Model to indicate the initial tack of the material. The initial viscosity tester CNY-1 is designed by the three-station ball method, which greatly improves the test efficiency. The test angle is adjustable from 0 to 60°, which can meet the needs of diverse laboratory experiments in colleges and universities. It can be completed in self-adhesive labels and labels. , initial pressure test of various adhesive products such as pressure-sensitive adhesive tape, protective film, plaster, and babu paste. College and university laboratory adhesive products initial holding tester 2. Adhesive testers for adhesives in colleges and universities; The CNY-2A Sticky Tester is a test for the continuous adhesion time of dry glue, labels, pressure sensitive tapes, protective films, plasters, etc. It is usually time to express the experimental results. It is Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. according to GB 4851- 1998 "Pressure-sensitive adhesive tape holding test method" developed and produced a testing equipment. Test principle of adhesive tester for adhesive products in colleges and universities: The adhesive test plate with the sample attached is vertically hung on the test frame, the weight of the specified weight is suspended at the lower end, the displacement amount of the sample is removed after a certain time, or the time when the sample is completely detached is used to characterize the adhesive product. Hold the sticky force. College and university laboratory adhesive product peel strength tester 3. Stripping strength tester for adhesive products in colleges and universities; Generally, the adhesive product has peeling if it is sticky, and the peeling strength of the adhesive product refers to the maximum force required when peeling the unit width from the contact surface, which reflects the bonding strength of the adhesive tape. Using the 180° peel strength tester BLJ-C of Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. to test the peel strength of the adhesive product is beneficial to the manufacturer to find a reasonable sizing degree. Experimental principle of peeling strength tester for adhesive products in colleges and universities: The test sample gel is faced with a standard test plate, rolled three times with a standard press roll, placed, clamped on a peeling test machine, and peeled off the sample and the test plate in the form of 180°, and the force value sensor records the force value during the peeling process, and then Dividing the strip width by the sample is the final peel strength. Electronic pressure roller testing machine for testing adhesive products in colleges and universities 4. Electronic pressure roller testing machine for testing adhesive products in colleges and universities It is the most suitable type of viscosity test for adhesive products. In the course of the experiment, it is necessary to borrow the adhesive belt rolling machine YGJ-S. The method of viscous experiment is specified in the relevant experimental standards, and the preparation of the pattern is the required auxiliary. equipment. The rolling machine is widely used in quality inspection institutions, packaging plants, tape factories and other units. Adhesive belt rolling machine test principle: the glass tape paper selected according to the standard and the sample ink printing surface adjusted by the test environment, the adhesive belt rolling machine is adhered to the standard load, rolling speed and rolling times. Put together, adjust for a certain period of time, and then perform a peel test. The state in which the ink layer of the sample was peeled off was observed to judge the bonding fastness of the printed ink layer. The above information is a brief introduction of Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. on the adhesive testing instrument for adhesives in colleges and universities. Looking for 180° peel strength tester, initial tack tester CNY-1, sticky tester CNY -2A, Adhesive belt rolling machine YGJ-S, please call Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd.
A digital Hotel Safe is a secure storage device found in hotel rooms that uses electronic technology to provide guests with a secure place to store their valuables. Unlike traditional hotel safes, which typically use a physical key or combination lock, digital hotel safes use a digital keypad or touchscreen interface to allow guests to set their own unique passcode.
Digital hotel safes offer several advantages over traditional safes. Firstly, they are more convenient to use, as guests can easily set and change their own passcodes without needing assistance from hotel staff. Secondly, they provide a higher level of security, as the passcodes are typically encrypted and more difficult to guess or crack compared to physical keys or combinations.
In addition to the passcode entry, digital hotel safes may also offer additional security features such as an audit trail, which records the date and time of each access attempt, as well as a tamper-proof design to prevent unauthorized access.
Digital hotel safes come in various sizes and designs to accommodate different types of valuables, such as laptops, jewelry, passports, and cash. They are typically mounted securely to a wall or inside a cabinet to prevent theft or unauthorized removal.
Overall, digital hotel safes provide guests with a convenient and secure way to store their valuables during their stay, giving them peace of mind knowing that their belongings are protected.
