鐵藝護(hù)欄噴塑的原材料是一種固性粉末，高溫熔化在各種護(hù)欄，柵欄等的表面，附著力保護(hù)層比較好。油漆是一種液體，液體的油漆可以用刷子刷在物體表面，有噴槍的也可以噴在物體表面，但是噴漆的時(shí)候，一不小心油漆會像水一樣流淌下來，出現(xiàn)水紋或者高低不平、疙疙瘩瘩的現(xiàn)象，但是一些技術(shù)好的工人就會出現(xiàn)噴塑和油漆較難辨別的狀況。

　　The raw material of iron guardrail spray is a kind of solid powder, which is melted at high temperature on the surface of various guardrail and fence, and the adhesion protection layer is better. Paint is a kind of liquid, the liquid paint on the surface, can use a brush with spray gun can also be sprayed on surfaces, but spray paint, paint will flow like water down, appear the phenomenon of water lines or rugged, bumpy, but some good technical workers will appear coating and paint are undistinguishable.

　　濟(jì)南鐵藝護(hù)欄噴粉過程中要注意吊具的導(dǎo)電性，吊具上的徐層不能太厚。設(shè)計(jì)吊架時(shí)，要求吊架牢固可靠，使用預(yù)烘的目的。一是去除工件上殘留的水分，二是保證一定厚度的粉末涂料很好地附著在工件表面，三是保證盡快均勻加熱工件，固化過程加快。

　　Ji 'nan iron guardrail powder spraying process should pay attention to the conductivity of the spreader, spreader on the xu layer can not be too thick. When designing the hanger, it is required that the hanger is firm and reliable, and the purpose of pre-drying is used. One is to remove residual moisture on the workpiece, the other is to ensure that a certain thickness of powder coating is well attached to the surface of the workpiece, and the third is to ensure that the workpiece is heated evenly as soon as possible, and the curing process is accelerated.

　　護(hù)欄產(chǎn)品根據(jù)自身特點(diǎn)，采用自動噴槍和手動噴槍補(bǔ)噴相結(jié)合的方式，目的是實(shí)時(shí)監(jiān)控粉末噴涂質(zhì)量，確保產(chǎn)品質(zhì)量穩(wěn)定。一般純多酚粉末涂料的固化條件為200℃，10min，固化溫度和時(shí)間可以通過調(diào)節(jié)加熱爐的溫度和鏈速來保證。

　　According to the characteristics of guardrail products, automatic spray gun and manual spray gun supplement spray method is used to monitor the quality of powder spraying in real time and ensure the stability of product quality. The curing condition of general pure polyphenol powder coating is 200℃, 10min, and the curing temperature and time can be guaranteed by adjusting the temperature and chain speed of the heating furnace.

　　使用冷風(fēng)干燥，干燥過程中對工件進(jìn)行檢查。對于允許的缺陷，如流掛、起泡、露底、粘孔等，可以在工件不干燥的情況下，用二甲基酮等稀釋粉末涂料。將其噴涂在缺陷表面并用余熱固化。對于重大缺陷，需要進(jìn)行修復(fù)。根據(jù)涂膜厚度選擇不同的處理方法。一般有三種方法：直接重新噴涂零件、機(jī)械研磨和用脫模劑處理。

　　Dry with cold air and check the workpiece during drying. For the allowed defects, such as flow, bubbling, bottom exposure, sticky hole, etc., can be in the workpiece is not dry, with dimethyl ketone and other dilution powder coating. It is sprayed on the defect surface and cured by residual heat. For major defects, repair is required. Choose different treatment methods according to film thickness. There are generally three methods: direct repainting of parts, mechanical grinding and treatment with release agents.

　　靜電噴塑工藝與傳統(tǒng)的噴漆工藝相比較，具有顯著優(yōu)勢，比如：對環(huán)境無污染，對人體無毒害；涂層外觀質(zhì)量優(yōu)異，附著力及機(jī)械強(qiáng)度強(qiáng)；噴涂施工固化時(shí)間短；涂層耐腐耐磨能力高出很多；有些施工場合已經(jīng)明確提出必須使用靜電噴塑工藝處理；靜電噴粉噴涂過程中不會出現(xiàn)噴漆工藝中常見的流淌現(xiàn)象，而且品種多，色彩豐富，可與各種環(huán)境融合，可根據(jù)區(qū)域環(huán)境選擇不同款式，彰顯個(gè)性。

　　Compared with the traditional painting process, electrostatic spraying process has significant advantages, such as: no pollution to the environment, non-toxic to the human body; The coating has excellent appearance quality, strong adhesion and mechanical strength. Spraying construction curing time is short; The corrosion resistance of the coating is much higher; Some construction occasions have been clearly put forward that electrostatic spraying process must be used; In the process of electrostatic powder spraying, there will be no flowing phenomenon common in the painting process, and there are many varieties and rich colors, which can be integrated with various environments. Different styles can be selected according to the regional environment to highlight the personality.
