Description
Technical Field
The invention relates to the field of fiber production, in particular to a continuous production electrolysis device for fibers.
Background
Polyvinyl alcohol (PVA) is a water-soluble polymer, and is obtained by alcoholysis of polyvinyl acetate, each repeating unit contains a hydroxyl group, and a large number of hydrogen bonds are contained in molecules and among molecules, so that the PVA molecule has high crystallinity, chemical stability, thermal stability and other performances. The average molecular weight of the polyvinyl alcohol fiber is 60000-250000, the thermal decomposition temperature is 200-220 ℃, and the melting point is 225-230 ℃.
As shown in figure 1, the existing scheme adopts PVA as raw material and mirabilite as coagulation bath; however, such a process has the following drawbacks:
1, the purity of the PVA fiber is not high, and the impurity is more;
2, the coagulation bath needs to use mirabilite, and the problem brought by mirabilite is that: the polyvinyl alcohol fiber preparation links in Chinese patent 201210416178.5 and Chinese patent 200610032535.2 adopt mirabilite solution with a certain concentration to be used as coagulation bath for spinning. In both patents, although the residual weight ratio of mirabilite is made to be less than 0.1% by the process, na2 so4.10h2o remained on the polyvinyl alcohol fiber is a strong electrolyte, and if such fiber is applied to the wound surface of the nursing human body, the water/electrolyte imbalance of the wound surface is caused, and the use risk is increased.
3, Byproducts such as sodium acetate and the like are generated in the process: alcoholysis of polyvinyl acetate can be carried out under acidic or basic conditions. The alkaline condition process has absolute advantage of economic benefit, so that the prior polyvinyl alcohol production mostly adopts sodium hydroxide and potassium hydroxide for alcoholysis. The alkaline alcoholysis has two alcoholysis processes, namely a high alkaline process and a low alkaline process in the PVA production process. The high-alkali method has the advantages of high alcoholysis speed, high production capacity, more side reactions, more sodium acetate content in PVA products, lower purity of PVA and high ash content; the low-alkali method has the outstanding advantages of low sodium hydroxide consumption, less side reaction, correspondingly less sodium acetate byproduct, low ash content and low alcoholysis speed due to low alkali mole ratio. The polyvinyl alcohol prepared by the high-alkali method or the low-alkali method can generate a certain amount of sodium acetate, and the existence of the sodium acetate has potential risks for wounds, because the exudate components of the wounds are mostly water, the water and the sodium acetate generate acetic acid and sodium hydroxide which are easy to volatilize, and the sodium hydroxide is taken as a strong alkali to cause certain harm. In addition, researches show that the wound surface of the human body is beneficial to healing in a slightly acidic environment, and the sodium hydroxide changes the alkalinity of the wound surface which is nursed by the polyvinyl alcohol fiber, so that the wound surface healing is not facilitated, and a pH value environment which is suitable for bacteria is generated, thereby increasing the infection risk. Ash is composed of fine particles which contain or adhere to many substances harmful to the human body, such as heavy metals.
4, Hydroxyl-OH is a polar group, can form a hydrogen bond with water of wound exudates, and has good adsorptivity to water molecules; acetate acetoxy-OCOCH 3 is an ester group that does not absorb water. It can be seen that for medical dressings, -OH properties are much greater than-OCOCH 3, which requires a very high degree of alcoholysis. When PVA alcoholysis degree is high, the volume of side groups-H and-OH is small, and the side groups can enter crystallization points without causing stress, so that hydroxyl groups in PVA macromolecules are mutually associated in a hydrogen bond mode, macromolecules are orderly arranged, water molecules are difficult to enter the PVA macromolecules, solvation is difficult, water solubility is poor, and performance is stable. When the PVA alcoholysis degree is low, the association of hydrogen bonds is further weakened due to the increase of-OCOCH 3, and the directionality of PVA macromolecules is destroyed, so that water molecules easily enter between the PVA macromolecules, and the dissolution effect of water on the PVA is improved. For a dressing for nursing a wound surface, the risk of leaving foreign matters on the wound surface is increased due to the existence of water in exudates.
The company develops a preparation method of PVA fibers, and patent numbers: PCT/CN2019/110559; PVAc (polyvinyl acetate) is adopted to replace PVA, and then an electrolytic coagulation bath is used in a matching way, so that mirabilite is not required to be used in the coagulation bath, PVA is obtained by alcoholysis of PVAc in an electrolytic cell, and the produced PVA fiber has high purity and few impurities.
In continuous production, electrolyte accumulation in the electrolytic cell can affect electrolytic reaction in the electrolytic cell or residual electrolyte pollutes fibers so that the fibers carry impurities, and the electrolytic cell is required to continuously produce the fibers.
