Glas bottelcoating is 'n belangrike oppervlakbehandelingskakel op die gebied van kosmetiese verpakking. It adds a beautiful coat to the glass container. In this article, we share an article about glass bottle surface spraying treatment & color matching skills.
Ⅰ、Glas bottel verf bespuiting konstruksie operasie vaardighede
1. Gebruik skoon verdunningsmiddel of water om die verf aan te pas by 'n geskikte viskositeit vir bespuiting. Na meet met 'n Tu-4-viskometer, is die geskikte viskositeit oor die algemeen 18 tot 30 sekondes. As daar tans nie 'n viskosmeter is nie, kan jy die visuele metode gebruik: roer die verf met 'n stok (yster of houtstok) en lig dit dan op tot 'n hoogte van 20 cm en stop om waar te neem. If the paint does not break in a short time (a few seconds), it is too thick; if it breaks as soon as it leaves the upper edge of the bucket, it is too thin; when it stops at a height of 20 cm, the paint is in a straight line and stops flowing and drips down in an instant. This viscosity is more suitable.
2. The air pressure should be controlled at 0.3-0.4 MPa (3-4 kgf/cm2). If the pressure is too low, the paint liquid will not be atomized well and pitting will form on the surface; as die druk te hoog is, sal dit maklik sak en die verfmis sal te groot wees, wat materiaal sal mors en die gesondheid van die operateur sal beïnvloed.
3. Die afstand tussen die spuitkop en die oppervlak is oor die algemeen 200-300 mm. If it is too close, it will easily sag; as dit te ver is, sal die verfmis ongelyk wees en sal daar maklik pittings verskyn, en as die spuitstuk ver van die oppervlak af is, sal die verfmis op die pad wegvlieg en vermorsing veroorsaak. The specific size of the interval should be adjusted appropriately according to the type, viscosity and air pressure of the glass bottle paint. The interval of slow-drying paint spraying can be farther, and it can be farther when the viscosity is thin; when the air pressure is high, the interval can be farther, and it can be closer when the pressure is small; the so-called closer and farther refers to the adjustment range between 10 mm and 50 mm. As dit hierdie reeks oorskry, is dit moeilik om 'n ideale verffilm te bekom.
4. Die spuitpistool kan op en af, links en regs geskuif word, verkieslik teen 'n eenvormige snelheid van 10-12 m/min. The nozzle should be sprayed flat on the surface of the object, and oblique spraying should be minimized. When spraying to both ends of the surface, the hand holding the spray gun trigger should be quickly released to reduce the paint mist, because the two ends of the surface of the object often receive more than two sprays, and are the places where dripping is most likely to occur.
5. Wanneer u bespuit, moet die volgende laag 1/3 of 1/4 van die vorige laag druk, sodat daar geen lekkasie sal wees nie. As u vinnig droogverf spuit, is dit nodig om dit tegelyk te spuit. The effect of re-spraying is not ideal.
6. When spraying in an open place outdoors, pay attention to the wind direction (it is not suitable to work in strong winds), and the operator should stand in the direction of the wind to prevent the paint mist from being blown onto the sprayed Verf film en veroorsaak 'n verleentheid van korreloppervlak.
7. Die volgorde van bespuiting is: Eerstens moeilik, maklik later, eers binne, later buite. Hoog eerste, laag later, klein area eerste, groot oppervlakte later. Op hierdie manier sal die Paint Mist wat later gespuit is, nie op die spuitverffilm spuit en die spuitfilm beskadig nie.
1. Basiese beginsel van kleur
Geel + pers = groen
2. Basiese beginsel van komplementêre kleure
Rooi en groen is aanvullend, dit wil sê rooi kan groen verminder, en groen kan rooi verminder;
Geel en pers is komplementêr, dit wil sê geel kan pers verminder, en pers kan geel verminder;
Blou en oranje is komplementêr, dit wil sê, blou kan oranje verminder, en oranje kan blou verminder;
Oor die algemeen word die kleur waaroor mense praat in drie elemente verdeel: kleur, ligtheid en versadiging. Hue is also called hue, ie red, orange, yellow, green, cyan, blue, purple, etc.; Ligtheid word ook helderheid genoem, wat die ligtheid en duisternis van die kleur beskryf; saturation is also called chroma, which describes the depth of the color.
4. Basiese beginsels van kleurpassing
Moenie meer as drie soorte verf vir kleuraanpassing gebruik nie. Mixing red, yellow and blue in a certain proportion can obtain different intermediate colors (ie colors with different hues). On the basis of the primary colors, adding white can obtain colors with different saturations (ie colors with different shades). On the basis of the primary colors, adding black can obtain colors with different lightness (ie colors with different brightness).
The mixing and matching of paints follows a subtractive color principle. The three primary colors are red, yellow and blue, and their complementary colors are green, purple and orange. The so-called complementary colors are two colors of light mixed in a certain proportion to obtain white light. The complementary color of red is green, the complementary color of yellow is purple, and the complementary color of blue is orange. Dit wil sê, as die kleur te rooi is, kan jy groen byvoeg; if it is too yellow, you can add purple; As dit te blou is, kan jy oranje byvoeg. Die drie primêre kleure is rooi, geel en blou, en hul komplementêre kleure is groen, pers en oranje. Die sogenaamde komplementêre kleure is twee kleure van die lig wat in 'n sekere verhouding gemeng is om wit lig te verkry. Die komplementêre kleur van rooi is groen, die komplementêre kleur van geel is pers, en die komplementêre kleur van blou is oranje. Dit wil sê, as die kleur te rooi is, kan jy groen byvoeg; As dit te geel is, kan u pers byvoeg; As dit te blou is, kan jy oranje byvoeg.
Before color matching, first determine the position of the color to be matched according to the figure below, and then select two similar hues to match in a certain proportion. Gebruik dieselfde glasbottelbordmateriaal of die werkstuk wat gespuit moet word om by die kleur te pas (die dikte van die substraat, natriumsoutglasbottel en kalsiumsoutglasbottel het verskillende effekte). As u die kleur pas, voeg eers die hoofkleur by en gebruik dan die kleur met 'n sterker kleurkrag as die sekondêre kleur, voeg stadig en af en toe by en roer voortdurend, en let op die kleurveranderings te eniger tyd, neem monsters en vee, borsel, spuit or dip them on a clean sample, and compare the color with the original sample after the color stabilizes. The principle of "from light to dark" must be grasped in the entire color matching process.
