济南护栏有哪些着色方法 -凯时app

济南护栏着色方法大略分为玄色型材挤出法、复合共挤法、覆膜法和表面咬涂法。

ji'nan ontario guardrail coloring method is divided into black extrusion method, co extrusion method, coating method and coating surface bite.

(1)玄色型材挤出法，也称通体法。在pvc异型材配方中参预色母料，经由挤出机直接挤出玄色型材。长处是在原挤出机上挤出成品，本钱低；不足是型材的耐候性差，难以满足室表里装璜成果的申请。

(1) black extrusion method, also known as the law. in the pvc profile formulation with black color masterbatch, profiles extrusion directly through the extruder. advantage is in the original extrusion machine extrusion products, the cost is low; inadequate profiles of poor weather resistance, it is difficult to meet the application of room inside and outside decoration effects.

(2)复合共挤法。由  和一层附加的玄色物料共同挤出构成的型材。该玄色物料无论是pvc，还是聚甲基丙烯酸甲酯大要丙烯酸—苯乙烯—丙烯酸酯共聚物(asa)，都须要两个挤出机主机(锥双蛹杆60或58和单螺杆30)来搞定。生制造型材必须应用一种复合模具，生制造唱功是往日自两个一致流道的型材物料和玄色物料，在离开模具前汇流到同一流迟中共同挤出成型。这种方法的赋性是：生制造过程中需另配冷热混合机或干燥机等设备，物料回收难度大，生制造唱功繁冗，复合膜具本钱高、投资大。

(2) co extrusion method. by the ji'nan guardrail and an additional layer of black material consisting of co extruded profiles. the black material whether it is pvc or pmma gist of acrylic acid styrene - acrylate copolymer (asa) need two extrusion machine (cone double pupa rod 60 or 58 and single screw 30) to get things done. production profile must be applied to a composite mold, manufacturing singing is past since two uniform flow of materials and black material, before leaving the die bus to first-class late in co extrusion molding. this method ascribed: students manufacturing process with hot and cold mixing machine or dryer equipment, material recovery difficult, production singing burdensome, the composite membrane with high cost, large investment.

(3)覆膜法。操作加热和机械覆膜的方法，经由压合将一层玄色膜和粘接胶粘接在济南护栏表面。赋性是：生制造过程需在流水线前途行，品质较好的膜和粘接胶需选用进口制造品，本钱较高；施工时玄色膜碰伤损不好将无法修补。

(3) plastic film method. operation method of heating and mechanical coating, by pressing a layer of black film and adhesive surface barrier in ji'nan. ascribed: manufacturing process line line in future, the better the quality of the film and adhesive need imported manufactured goods, the cost is higher; construction bumps with black plastic film and the loss of bad will not be able to repair.

(4)表面喷涂法。将玄色涂料均匀地喷涂在济南护栏的可视表面亡，可单面喷涂，也可双面喷涂。赋性是色彩多样，生制造施工灵活方便。

(4) surface spraying method. the black paint evenly sprayed on the visible surface of ji'nan guardrail die, single-sided spraying, spraying can also double. nature is the color variety, the production of flexible and convenient construction.
