Buy cold [preferred] 1. Shandong Huayu civil cold it is more of a cold storage construction, to be built single or multiple layers. The main building is generally reinforced concrete frame structure or masonry structure. Envelope cold civil genus heavy body structure, the thermal inertia of the larger outer polyurethane cold storage doors, diurnal fluctuations in the outdoor air temperature and envelope surface solar radiation caused by the diurnal temperature fluctuations greater attenuation in envelopes, so inner envelope surface temperature fluctuations on small, easy to storage temperature will stabilize. 2. The combination of this cold cold plate as a single form, the library board for lightweight prefabricated steel frame insulation board assembly structure, its load-bearing member to use more thin-walled steel production. Inside and outside the library board panels are color steel (galvanized steel substrate), the core material for the library board of rigid polyurethane foam or polystyrene foam board pasted. Because in addition to the ground, all the components are in accordance with uniform standards of professional factory pre-sets, refrigerator door assembly at the site of production, construction progress so fast, short construction period. Refrigerator door [preferred] Shandong Huayu maintain cold: cold sterilization and disinfection addition to mold cold refrigerated cooking ingredients and food have contain some fat, protein and starch. The presence of these nutrients, causes the growth of mold and bacteria multiply. To do cold She refrigerator door wholesale health management, quality assurance frozen Tocumen food and cooking ingredients, it is necessary to carry out regular cold She sanitation and disinfection work. In addition to killing mold and mildew cold sterilization, to use acid disinfectant. Acids disinfectant sterilization, primarily solidified bacterial proteins. Common disinfectants have lactic acid, peracetic acid has, bleach, formalin. Cold storage doors, Fitch machinery (certified), Tonghua Tocumen provided by Fitch Machinery Co., Ltd. Shandong.
