玻璃钢浮雕最常见的问题有起皱、针眼、胶衣树脂剥落、发粘、纤维显露、起泡、开裂或龟裂、白化、制品变形、硬度差和刚性低。下面郑州玻璃钢浮雕小编就对每个问题进行一一总结。
The wrinkling, stythe eye of a needle, gel coat resin stripping, sticky, exposing the fiber, foaming, cracking or crazing, whitening, product deformation, hardness difference and low rigidity glass embossed steel is the most common problem. Zhengzhou glass steel relief under the small series on each issue one one summary.
1, wrinkle: gel products often occurs. Is due to the applied in the auxiliary layer before using resin, gel coat resin curing is not complete, make auxiliary layer resin monomer partial dissolution of the gel coat resin, caused by thermal expansion, resulting in wrinkles.
解决方法。(1)、控制胶衣层厚度,使其在0.3mm—0.5mm,400—500g/m2。(2)、胶衣树脂完全固化后再加辅层树脂。(3)、树脂的成分、催化剂的加入量、颜料糊对固化的影响都要严格控制。(4)、环境温度要控制在20度左右。
Solution method. (1), coating layer thickness control, the 0.3mm - 0.5mm, 400 - 500g/m2. (2), gel coat resin fully cured resin plus auxiliary layer. (3), the composition of the resin, the amount of catalyst, and the influence of pigment paste on the curing are all strictly controlled. (4) the ambient temperature should be controlled at about 20 degrees.
2, eye gel: before the small bubbles into the resin will cause needle, mold surface dust will also cause needle.
解决方法。(1)模具表面无灰尘。(2)保证树脂的粘度。(3)选用正确的脱模剂,脱模剂选用不当,可造成胶衣层不能很好的浸湿,从而引起针眼。(4)、加催化剂和颜料糊时应防止空气混入树脂。(5)、喷枪功率太大也会产生针眼。(6)催化剂过量使其过早凝胶会产生气泡从而产生针眼。
Solution method. (1) no dust on the surface of the mold. (2) the viscosity of the resin. (3) use correct release agent, release agent improper selection, caused by soaking gel coat layer can not be very good, which is caused by the eye of a needle. (4) in the presence of catalyst and pigment paste, the air should be prevented from mixing with the resin. (5), the gun power is too large will have a needle. (6) the excessive catalyst will produce bubbles resulting in premature eye gel.
3, coating resin is due to spalling: between gel coat resin with a laminated adhesive products caused by the bad. In the demolding process will also appear on.
解决方法。(1)模具表面多抛光几次,使胶衣树脂不会粘附在模具上。(2)避免使用软的、能渗透胶衣树脂的石蜡。(3)在铺敷之前保持胶衣表面清洁,否则会使辅层用树脂与胶衣树脂粘结不好。(4)在开始辅层时控制好胶衣树脂的固化时间。不能固化很长时间后才开始辅层。(5)控制好凝胶时间。太短了,不能充分压实。
Solution method. (1) die surface polishing several times, so that the gel coat resin will not adhere to the mold. (2) to avoid the use of soft, can penetrate the gel coat resin wax. (3) to keep the surface clean before laying in the gel, otherwise it will make the auxiliary layer with resin and gel coat resin bond is not good. (4) curing time control gel coat resin at the beginning of auxiliary layer. Can not be cured after a long time to start the auxiliary layer. (5) control the time of the gel. Is too short, can not be fully compacted.
4, hair stick: exposed to the surface of the products in the air, due to the curing is not complete and sticky.
郑州玻璃钢浮雕解决方法。
Zhengzhou glass steel relief method.
(1)避免在寒冷、潮湿条件下铺敷。
(1) to avoid the cold, wet conditions under application.
(2)用空气干燥的树脂作最后涂层。
(2) the final coating is made of air dry resin.
(3)、尽可能增大催化剂促进剂用量。
(3), as far as possible, increasing the amount of catalyst accelerator.
(4)、提高固化温度。
(4) improve the curing temperature.
(5)、在外涂层加石蜡油或石蜡。
(5), in the outer coating with paraffin or paraffin.
解决方法。(1)胶衣层太薄,增加胶衣层厚度或者在胶衣层和层压材料之间放一层细毡。(2)在胶衣层充分固化前开始铺敷。(3)脱模不能太快。(4)层压制品内放热温度太高。可以减少催化剂-促进剂的用量,也可以改换催化剂。
Solution method. (1) gel coat layer is too thin, increase the gel thickness or put a layer of fine felt between the gel coat layer and laminated material. (2) in the gel coat layer is fully cured before the start of laying. (3) the release can not be too fast. (4) the exothermic temperature of the laminate is too high. Can reduce the amount of catalyst - accelerator, also can change the catalyst.
6, foaming: will appear on the surface. May be in a very short time after the release or in the post curing period, it may be in a few months after the release of the release. Is due to air or solvent sandwiched between gel coat resin and laminates may also choose the wrong application under the special conditions of the resin and reinforcing material caused by the.
解决方法。(1)使用时玻璃纤维浸渍不充分,要充分压实。(2)材料、胶衣层被水或清洗剂污染,应保证刷子或压辊干燥。(3)使用不当的催化剂高温固化,改换催化剂。
Solution method. (1) the use of glass fiber impregnation is not sufficient, to fully compacted. (2) material, gel coat by water or cleaning agent pollution, should ensure that the brush or roller drying. (3) the use of improper catalyst high temperature curing, change the catalyst.
7, cracking or crazing: This is generally happen soon or months after curing. On the surface of the resin surface cracks, shiny black.
解决方法。(1)胶衣层太厚,应保持在0.4mm左右。(2)树脂选择不当。(3)催化剂用量不当。(4)过量的苯乙烯加到胶衣层上。(5)树脂固化不完全。(6)树脂中加入的填料过量。
Solution method. (1) gel coat layer is too thick, should be kept at about 0.4mm. (2) improper selection of resin. (3) the amount of catalyst is inappropriate. (4) styrene added to the gel coat on the excess. (5) the curing of the resin is not complete. (6) excess filler added to the resin.
解决方法。
Solution method.
(1)胶衣树脂固化不完全,是否因为厚度不合适、促进剂、催化剂用量不正确。
(1) gel coat resin curing incomplete, if not appropriate, because the thickness of catalyst promoter, is not correct.
(2)使用颜料或填料不当。
(2) improper use of pigment or filler.
(3)填料、颜料过量。
(3) excess filler, pigment.
郑州玻璃钢雕塑解决方法。(1)制品脱模时固化不完全。(2)增强肋强度不够。(3)在脱模之前,把富树脂层涂在制品的背面,保持胶衣层的平衡。(4)改进制品设计,抵消弯曲应力。
Zhengzhou glass steel sculpture solution. (1) when the product is not complete, the product is not completely cured. (2) reinforced rib strength is not enough. (3) before the demolding, the resin layer is coated on the back of the rich products, keep the balance of the gel coat. (4) improved product design, offset bending stress.
10, the hardness difference and the rigidity is low: it is not entirely caused by the product curing.
解决方法。
Solution method.
(1)检查促进剂和催化剂的用量。
(1) the amount of the catalyst and catalyst is examined.
(2)避免在寒冷和潮湿情况下铺敷。
(2) to avoid the cold and wet condition with lower berth.
(3)确保玻璃毡在干燥条件下保存。
(3) to ensure that the glass mat is kept under dry conditions.
