Professional operation - Paste formulation and system improvement (2)

Based on the above points, it is recommended to select a paste mixing system with the following functions:

1. The deployment of small quantities, the required deployment time is short. 2. Not limited by the starch used, various starches can be used, such as corn, wheat, cassava and potatoes (potato);
3. Each batch of selected recipes is accurate. Ensure that there is no quality difference in the batches of the formulated paste;
4. Have the function of storing each paste formulation and can make modifications when needed;
5. Multi-discipline deployment function;
6. Using the high shear stirring method, the viscosity of the paste is stable and does not decrease with the use of time;
7. The standard gelatinization temperature and the ratio of powder to water;
8. The equipment should be easy to operate and less maintenance. High efficiency, high rate of return. The performance is good, the instrument is precise and accurate.

Sembcorp Linfu (Shanghai) Machinery Manufacturing Co., Ltd. has automated paste dispensing equipment with precision-designed paste preparation systems with more than one function. The system has a high-shear mixing design: the use of sophisticated computer control ensures that accurate paste formulations and raw materials (such as starch, water, caustic soda, borax) are injected, accurate control of mixing time, temperature and batch, etc. . There are three models of the system: standard manual, semi-automatic and fully automatic operation, for their own manufacturers, purchase. Semi-automatic can be upgraded to fully automatic control in the future. This system was chosen to minimize human error.

Our system has changed the way we used to, and this system is capable of dispensing small batches and multiple formulations of pastes. Each batch only takes 20 to 30 minutes, so that you can provide different pastes to suit different requirements. Used at the corrugating machine. It can help your operator to easily change and adjust the formula, modify the formula to be satisfied, and fully adapt to the requirements of the machine. The equipment can also adjust a batch of paste in a short time, because it uses "high shear" technology. Another effect of the "high shear" stirring technique is the stable paste viscosity, which keeps the paste from being "sheared" and "thinning" as it loses its original function. During the deployment process, our system uses the highest shear agitation under controlled conditions to bring the viscosity of the paste under a stable threshold, making it stable for a longer period of time. (Figure 2, Figure 3)

The use of multi-formulation pastes in this way has a significant meaning in the production of corrugated board. It will eradicate the three major problems faced by the manufacture of cardboard: the unstable viscosity of the paste, the quality of each batch of paste, and the frustration of a single recipe. . In other words, the operator of the corrugator machine can be assured to set the appropriate amount of paste, without having to consider increasing the amount of paste, reduce the moisture content in the actual situation, increase the speed of the corrugating machine, and improve the quality of the corrugating machine. cardboard. I believe that you will find that the downstream boxing process will benefit from the optimization of the board quality.

Sembcorp Linfu (Shanghai) Machinery Manufacturing Co., Ltd. APS360-type high-quality automatic paste equipment deployment out of the stable quality, suitable for different environmental needs of the paste can bring the following benefits:

1. No longer use chemical starches and additives, such as bridging agents, stabilizers, etc.;
2. The starch granules distend evenly, the viscosity of the paste is extremely stable, and the viscosity changes within ± 1 second;
3. Improve the solid content of the paste powder to water ratio, save steam consumption 15% -30%;
4. Reduce the amount of paste, the unit area usage of three layers of paperboard will save 1 g/m2 - 2 g/m2;
5. Corrugated board machine speed increased 5% -10%;
6. The corrugated board is smooth, has good adhesive force, reduces the defective rate, and reduces the loss rate of the base paper by 25% to 50%;
7. The latter stage of processing is smoother and delivery is more timely;
8. Fully automated paste preparation system with short deployment time (20 minutes to 30 minutes/lot), which facilitates the change of pastes of multi-type and multi-format corrugated paper machines. Terminals can be arranged in the central control room and managed by the central control room staff. Operation, saving manpower.

Sembcorp Linfu (Shanghai) Machinery Manufacturing Co., Ltd. professionals will be happy to share with you the experience of paste formulation and blending technology, provide consulting services, explain to you in detail the characteristics and characteristics of each paste, and their production of corrugated board The impact that can be produced. It is proved that after installing a new paste system, the benefits will be long-term high-performance operation and effective cost control.

The European and American corrugated cartons have all changed the old paddlers and used the new paste formulation system.

The Middle East and Europe (including Russia) have also started operations. After they used the system in Australia (Australia), they were highly rated and satisfied. Has ordered more than one. In Asia, customers learned that due to the reduction of costs, paste machines can improve the quality of pastes by using only ordinary starch. In China, there are six carton factories that have purchased our own paste preparation system for their new plants. Experience tells us that high returns and high efficiency are absolutely not wrong.
