The Brief Introduction of the whole production process of gypsum board

1. The gypsum powder calcination area can be divided into the following steps according to the conveying process of the gypsum powder: gypsum raw material storage yard, grinding & drying, calcining, cooling, grinding and storage. Gypsum before calcination is mainly composed of dihydrate gypsum, calcined is the process of converting dihydrate gypsum into hemihydrate gypsum, and calcined gypsum is hemihydrate gypsum as the main component.

2. The dry addition area includes: gypsum powder, starch, coagulant, retarder, refractory, cement, etc., according to the types of additives. The functions of various additives are different, and individual additives may not be used. However, these are not the only additives, and they are not listed here. The first three additives in general factories are essential.

1. The wet addition area is also based on the types of additives, including: water, water reducing agent, soap solution, soap solution water, air, glue system, water-resistant agent, etc., of which soap solution, soap solution water, and air produce bubbles In a system, the wet addition is basically transported to the mixer through pipes, pumps and flow meters. Any dry additions and wet additions are finally transported to the mixer to be fully mixed into gypsum slurry.

4. The mixing area includes the following main items according to the arrangement and process of the equipment: paper support, paper receiving platform, paper storage mechanism, paper pulling roller, paper tension, paper correction and positioning, paper printing or printing, paper scoring, mixer , forming platform, extruder. Nowadays, with the popularity of automatic paper splicing machines, the paper preparation process has become simpler, reducing human errors, and the success rate of paper splicing is getting higher and higher. The mixer is one of the main equipment of the entire gypsum board production line, so the maintenance and maintenance of the mixer is particularly important, mainly to reduce the downtime caused by the mixer. From the moment the gypsum powder enters the mixer, it begins to gradually convert from hemihydrate gypsum to dihydrate gypsum. The hydration process is carried out until the inlet of the dryer, and it is gradually converted into dihydrate gypsum, until the main component of the finished dry gypsum board is dihydrate gypsum. Gypsum.

5. The forming area mainly includes: coagulation belt, coagulation belt cleaning device, belt rectifier, tapered belt, paper wheel, bonding water, forming pressure plate, forming presser foot, spray water, etc. The formed gypsum board is on the solidification belt Gradually solidify to meet the requirements of cutting. Gypsum board is shaped well and badly here. Here, the attention and dexterity of the operators are relatively high, and the probability of waste products is low.
