In the early19870s, SMD appeared in the electronic industry as a "sealed lead-free crystal carrier", which is usually referred to as HCC for short.
Heavy calcium carbonate (HCC) is made by directly crushing natural calcite, limestone, chalk, shells, etc. by mechanical methods. Because its sedimentation volume (1.1-1.9 ml/g/g) is smaller than the light calcium carbonate produced by chemical method (2.4-2.8mL/g), it is weighed.
At present, calcium carbonate has been widely used in papermaking, plastics, plastic films, chemical fibers, rubber, adhesives, sealants, daily chemicals, cosmetics, building materials, coatings, paints, inks, putty, wax sealing, putty, felt packaging, medicine, food (such as chewing gum and chocolate) and feed, and its functions include: increasing product volume, reducing cost and improving processing.

HCC community was founded in 2000, and by the end of 20 13, HCC had gone through 13 years. In 2000, our school built a Gigabit Ethernet campus network, and the Youth League Committee used the campus network to carry out three class webpage design competitions and individual webpage competitions, and a number of network technology experts emerged. These students spontaneously set up an organization club called HCC.
With the strong support of the Youth League Committee of our school and the education department, HCC created the website "Red Flag Fluttering" and became the first founder of the website for middle school students in the history of our school. It was uploaded to the Internet at the end of 2002, which became an important window and stage to show the elegance of our students.
The working concept of HCC is also permeated with "HCC", that is, "efficient, innovative and cordial", which means "efficient work, innovative development and enthusiastic service to all students" in Chinese.
Through self-recommendation, HCC Society elected CEO. Under the leadership of CEO, all members learn from each other and cooperate with each other to realize their self-worth in the hard and happy creative process. Although the CEO of HCC has changed from Fang Zhe to Liu Jiahe for six times, and the style of the organization is constantly innovating, the working concept of "building excellent network culture and serving the healthy growth of students" has never changed.
HCC community is a comprehensive community with web page making as its core. The community builds a colorful activity platform around the website, which enriches students' learning activities and displays their personal specialties, greatly reducing the limitations of time and space, strengthening students' learning interaction and igniting their learning enthusiasm.
From 2000 to 2008, HCC*** held seven web page making competitions. In early 2004, the Youth League Committee of Haidian District handed over the task of hosting the first "patriotic and national spirit theme web page design competition" in Haidian District to HCC.
Members have gained more training and development from successfully winning the free server sponsorship of Qianlong. Overcome the "hacker" attack and successfully realize the technical operation of the online course selection webpage for middle school students in the whole region. Red flag fluttering website is gradually maturing in the practice of network moral education.
During the competition, HCC led all classes in the school to establish a class website, and in 2005, the school community website was established to realize paperless office, community registration, activity application and announcement.
Nowadays, the revised HCC website has set up an original and simple forum called "Eleven Circles", which has expanded the communication platform for students. The website also takes advantage of students' desire for online communication, and regularly opens "moral chat rooms" for organized discussions and targeted guidance. Students complete the process of self-education while participating in online activities.
Since 2009, the "Eleventh Website Group" plan has been implemented, and the virtual community of the Eleventh Campus has been launched. At present, there are also class space, eleven calendars, college entrance examination volunteer consultation network and eleven electronic maps.
At present, there are nearly 20 members in HCC community, which consists of four departments: technology, news, publicity and activities. They cooperate and coordinate with each other, hold school-level computer evenings regularly, develop software, guide and help teachers to make courseware, and train students in computer knowledge. Every year, we hold recruitment activities from the whole campus, constantly update and recruit talents from all walks of life. HCC is a five-star club in our school.
With the extensive selection activities of "Top Ten Students in Eleven Schools" and "Touching Eleven Schools", HCC adhered to the principle of serving students and immediately added a corresponding voting system to its website, which has now become a common tool, greatly improving the efficiency of the activities.
In addition, the Society has also carried out many other activities, such as the keynote speech contest, HP's "circular dragon" environmental protection activities, the construction of the inquiry system for sports meetings, and the "turning waste into treasure" environmental protection activities. The graffiti contest held in 2009 provided excellent wall graffiti designers for the exclusive studio of HCC Society, and the completion of the studio transformation led HCC Society to a new height.
In July, 2004, at the National Network Association Conference held in Beijing, our society was invited as the only representative of middle school students and was honored to be a member of the National Network Association. This is an affirmation of the innovative spirit of HCC, and it is also an affirmation of developing students' main role and exploring network moral education in our school in recent years.
With the deepening of influence, the diversification of activities and the specialization of technology, the HCC club in No.11 Middle School is absorbing more outstanding talents and cultivating talents, which fully shows the spirit of innovation, initiative and willingness to practice of middle school students, is a leader in the club construction process and a practitioner of new teaching concepts, and is an outstanding model for cultivating students' quality development.
I believe that the efforts of community members will eventually lay solid seeds for their lives, bear fruit and write new glories.
