Methods and systems are provided for mapping and linking elements in a document to corresponding fields or queries in a database. A document is annotated with structural elements of a markup language, such as Extensible Markup Language (XML), in order to map portions of the document to the corresponding database. Once individual elements within the document are mapped and linked to corresponding data fields or queries within a selected database, changes made to individual elements within the document automatically cause updates to corresponding data in the database to which those elements are mapped and linked. Conversely, changes made to individual data fields within the selected database automatically update corresponding elements within the document.

In a glue stick for a hot-glue device, in particular a glue gun, having an external contour which has a length and a diameter, a given ratio of length to diameter is in the range from 1:1 to 7:1.

The invention discloses a method for treating spent glue by using an acid-base solution. The method comprises the following steps of: deprivation of the stickiness of a glue stick: exposing one glue stick having a mass of m<s> and marked as No. 1 in the air, putting another glue stick into an air-blowing electrothermal constant-temperature drying box, setting a temperature to be 80 DEG C, and baking the another glue stick for 40 min to deprive the stickiness of the another glue stick, marking the another glue stick as No. 2, and, namely marking a normal glue stick without any treatment as No.3; stickiness recovery of the glue stick: treating the glue stick No. 2 with the acid-base solution, and checking the stickiness recovery effect of the glue stick; and stickiness recovery test: carrying out a peeling test and measuring stickiness retention time after the stickiness is recovered. The beneficial effects of the invention are as follows: after the glue stick No. 2 has been soaked in oxalic acid with a concentration of 5% for 30 min or has been soaked in acetic acid and in an oxalic acid with a concentration of 10% for 15 min respectively, the stickiness of glue stick No. 2 is wellrecovered, and the stickiness retention time is long; the stickiness of the glue stick is recovered in a simple and feasible manner; and the waste rate of glue sticks is lowered, which is of certainsignificance to conservation of resources and reduction of environmental pollution.

A solid adhesive is described that has an excellent finish, a light coating feeling, and is also capable of adhering to paper, wood, cloth, and the like. The solid adhesive contains water, an organic solvent, a gelation agent such as a dibenzalide of pentavalent to hexavalent sugar alcohol, and a polyvinyl formal resin.

A feed type solid adhesive may be provided, including a feeding container that is filled with the solid adhesive described above.

The invention provides a solid glue stick capable of correcting text and a preparation method thereof. The solid glue stick uses polyvinyl formal glue as a film-forming agent and an adhesive, and is added by adding excipients stearic acid and a moisturizing agent. It is prepared from glycerin and covering agent titanium dioxide, and the preparation method includes the following steps: a) preparing polyvinyl formal glue, b) adding and mixing, and c) filling and molding. The invention discloses a solid glue stick capable of correcting characters and a preparation method thereof. The solid glue stick has simple preparation process, low production cost, good environmental protection performance, not only has better paper bonding function, but also can realize convenience and high efficiency It has great market application value.

The invention relates to a solid glue stick, comprising 40-50 parts of polyvinyl alcohol, 30-40 parts of formaldehyde, 5-7 parts of urea, 5-20 parts of sodium stearate, 3-8 parts of sodium hydroxide and 3-8 parts of hydrochloric acid 3-10 parts of glycerin, 3-10 parts of ethylene glycol. The invention has the advantages that: through reasonable proportioning, the produced glue stick not only has good viscosity, but also is moist and not easy to dry.

The invention belongs to the technical field of polymer binders, and particularly relates to an anti-aging hot melt adhesive containing a compound antioxidant, which comprises a gun body, a heating pipe and an alcohol tank. A first cavity is formed in the gun body; the first cavity is designed to be in an L shape; a first through groove is formed in the bottom of the gun body in the first cavity;the first through groove is communicated with the outside; a sealing plug is mounted in the first through groove; a limiting sheet is fixedly connected to the L-shaped junction of the first cavity; aconnecting cover is fixedly connected to the limiting sheet; a connecting groove is formed in the side, facing the first through groove, of the connecting cover; the side wall of the connecting grooveis in threaded design; and limiting plates which are uniformly distributed are fixedly connected to the side wall of the side, far away from the alcohol tank, of the limiting sheet in the first cavity. Polyvinyl butyral brush-coats the surface of a hot melt adhesive rod prepared by extrusion to form a high-melting-point protective film, so that the phenomenon that the surface of a low-melting-point hot melt adhesive rod is sticky when the low-melting-point hot melt adhesive rod is used in a high-temperature environment can be effectively prevented.
