Repair method of stone wear

Stone is not a thing that exists in a vacuum, and it will inevitably have cracking damage during handling, processing and use. Once the stone is worn, it will seriously affect the aesthetic effect of the decoration. Since this wear is unavoidable, how should we fix it? This article will briefly introduce the method of stone wear repair.

penetration

Infiltration is a process of infiltrating a crack in a plate that has not been broken apart, and curing after a certain period of time to achieve bonding and increase the firm strength of the sheet.

(Formulation of osmotic gel: 307 unsaturated resin 100%; styrene 60-100%; cyclohexanone 4-5%; cobalt naphthalate 3-4%.)

Production Method:

(1) The 307 unsaturated resin and styrene are uniformly blended in the above ratio;

(2) Pour in the peroxone and mix well.

(3) Then pour in cobalt naphthalate and stir well. The best osmotic gel is that the osmotic gel can flow into a line when the osmotic gel is poured. At this time, the viscosity is the best and the osmosis effect is the best.

Infiltration process:

(1) Cool and dry the hair plate, conditionally use strong wind to dry the gap to ensure no moisture.

(2) Pouring the infiltrated glue along the crack with a small spoon, and it is preferable to make a small vibration to the board during the pouring process.

(3) It is good to cool the sun until the osmotic glue is not sticky.

Precautions:

The 307 unsaturated resin cannot be directly blended with cyclohexanone peroxide and cobalt naphthalate, and the cyclohexanone peroxide and cobalt naphthalate alone cannot be directly mixed. And how much should be used, or used side by side.

Stone bonding

Preparation of adhesive: 307 unsaturated tree fat 100%; cyclohexanone peroxide 4-5%; cobalt naphthalate solution 3-4%. In the preparation, the 307 resin and the cyclohexanone peroxide are first mixed, and then the cobalt naphthalate is mixed. And use as much as you need, and do not use more than 10 minutes.

Operation when bonding:

(1) Qinghao bonding surface, to achieve waterless, dust-free.

(2) Evenly apply adhesive on the bonding surface, taking care not to be too thick.

(3) Immediately after the glue is applied, the joint is pressed and squeezed tightly to make the adhesive slightly overflow. And choose flat or vertical stick according to the material. In addition, for small area cracking can be used for 502 instant glue or strong glue bonding.

Stone repair

The repair here refers to a process in which sand holes, pits, or damaged corners on the finished product are filled with a glue that is similar in color to the finished product.

Preparation of repair glue: epoxy resin 100% (601 or 634); ethylene diamine 8% -10%; and appropriate amount of toner, with appropriate amount of lithopone, talcum powder and other fillers blended.

Patched operation:

(1) Qinghao repair site, so that the repair site is dust-free, water-free and dry.

(2) Fill and smooth with repair glue, and prevent the repair glue from collapsing.

(3) Then solidify, the curing time is generally 2-4 hours (in winter, it may take 8-10 hours due to low temperature). In addition, it is also possible to use an adhesive glue and a toner as a repairing glue.
