Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] Concrete technical route of the present invention is:

[0028] 1. Hot soak replacement

[0029] This stage is to replace the moisture in the saturated wood components with some dimensional stabilizer, so that the wood components will not be damaged due to the volume expansion of the ice in the wood when the wood components are pre-frozen. The processing steps are as follows:

[0030] (1) Wash the wood components to be treated (if necessary, oxalic acid, sodium dithionite and other reducing agents can be used for preliminary decolorization), then measure the size, balance, take pictures, draw and record;

[0031] (2) Perform necessary binding, clamping, supporting and other work depending on the condition of the utensil, so as not to affect the contact with the dimensionally stable impregnating liquid;

[0032] (3) Immerse the utensi...

Abstract

The invention relates to a solidification method and equipment for unearthed bamboo and wooden wares. The solidification method comprises the following steps of: (a) pre-treating: cleaning a ware to be treated, weighing the ware and recording the weight; (b) performing hot-dip replacement: dipping the ware in a closed vessel which is filled with solution of antibacterial solidifying agent for the hot-dip replacement, wherein the solution of the solidifying agent consists of multiple parts of PEG solution from low concentration to high concentration; (c) measuring an eutectic point: detecting the eutectic point of the solution of the solidifying agent and the solution in the ware to determine a pre-freezing temperature after the hot-dip replacement is finished; and (d) performing freezing sublimation: reducing the temperature of the ware to the pre-freezing temperature by cold air freezing and performing vacuum sublimation for dehydration. The equipment comprises a pre-freeze drying device, wherein the pre-freeze drying device comprises a sealed tank in which multiple layers of shelves are arranged, and provided with a condensing device, a heating device, a vacuum device, a refrigerating device, a weighing device and an electric control device. Through the method and the equipment, integrated operation of the pre-freezing device and the sublimation dehydration device is realized, and the problems such as dehydration of large-sized wooden cultural relics and the like are solved while the structure of the equipment is simplified through the overall coordinated operation of the electric control device and by matching the ware shelves.

Description

technical field [0001] The invention belongs to the technical field of protection and restoration of cultural relics, and in particular relates to a method and equipment for solidifying unearthed bamboo and wood ware. Background technique [0002] The dehydration reinforcement of water-saturated cultural relics is an important part of cultural relic protection. When water-saturated cultural relics are excavated, the interior is full of water. Due to the action of the underground environment and microbial erosion, there are varying degrees of degradation, and some are very bad. Moisture seeps out with a light touch. For display or archaeological needs, such cultural relics usually need to be dehydrated and stored in a dry environment. Since the material of cultural relics is quite weak, in order to support the structure and prevent shrinkage and cracking due to drying stress during drying, it is usually impregnated with fillers before drying, and through the natural diffusio...
