注塑級(jí)黑色母粒是一種專門用于注塑加工的添加劑，其作用是將塑料原料中的色素、光穩(wěn)定劑等添加進(jìn)去，從而達(dá)到改變塑料顏色、提高其耐光性等效果的目的。下

一、注塑級(jí)黑色母粒的種類

注塑級(jí)黑色母粒通常有兩種，一種是高濃度母粒，另一種是低濃度母粒。高濃度母粒中添加的色素濃度較高，通常在40%左右；而低濃度母粒中添加的色素濃度較低，只有15-20%左右。不同濃度的母粒適用于不同的加工要求，用戶可以根據(jù)自己的實(shí)際需求來選用。

二、注塑級(jí)黑色母粒的作用

1、提高塑料材料的顏色

注塑級(jí)黑色母粒的主要作用就是提高塑料材料的黑色程度，使其在外觀上更加飽滿，美觀。這對(duì)于那些對(duì)外觀要求比較高的產(chǎn)品來說尤其重要，比如家具、汽車、電器等。

2、增強(qiáng)塑料材料的耐光性

注塑級(jí)黑色母粒中有一些光穩(wěn)定劑，其作用就是提高塑料材料的耐光性，防止其受到紫外線等外界因素的影響而失去原有的性能，延長使用壽命。

3、改善塑料原材料的性能

除了改變塑料的顏色和增強(qiáng)耐光性之外，注塑級(jí)黑色母粒還可以在一定程度上改善塑料原材料的的性能，比如增加它的強(qiáng)度、硬度等。

三、應(yīng)用范圍

注塑級(jí)黑色母粒的應(yīng)用范圍非常廣泛，幾乎所有需要改變塑料顏色、提高耐光性或改善塑料性能的行業(yè)都會(huì)使用到它，比如家具、電器、汽車、電子等。

四、選購方法

1、關(guān)注母粒的質(zhì)量

注塑級(jí)黑色母粒的質(zhì)量是非常關(guān)鍵的，如果選錯(cuò)了質(zhì)量不夠好的母粒，就會(huì)導(dǎo)致加工后的產(chǎn)品在外觀、性能等方面都不能滿足要求。因此選擇時(shí)需要重視母粒的質(zhì)量，盡可能選擇一些知名品牌的產(chǎn)品。

2、看濃度

不同濃度的注塑級(jí)黑色母粒適用于不同的加工類型，用戶需要根據(jù)自己的實(shí)際需求來選擇對(duì)應(yīng)的濃度。

3、關(guān)注成分

購買注塑級(jí)黑色母粒時(shí)，需要仔細(xì)查看成分表，確定是否包含有害物質(zhì)，以免影響產(chǎn)品質(zhì)量和安全。

Injection grade black masterbatch is a kind of additive specially used in injection molding processing, its role is to add pigments and light stabilizers in plastic raw materials, so as to achieve the purpose of changing the color of the plastic, improve its light resistance and other effects. Next

I. Types of black masterbatches for injection molding

There are usually two kinds of black masterbatches for injection molding, one is high concentration masterbatches and the other is low concentration masterbatches. The concentration of pigment added in the high concentration masterbatch is higher, usually around 40%; while the concentration of pigment added in the low concentration masterbatch is lower, only around 15-20%. Different concentrations of masterbatches are suitable for different processing requirements, users can choose according to their actual needs.

Black masterbatch for injection molding

Second, the role of injection molding grade black masterbatch

1、Improve the color of plastic materials

The main role of injection black masterbatch is to improve the black degree of plastic materials, so that it is more full in appearance, beautiful. This is especially important for those products with high requirements for appearance, such as furniture, automobiles, electrical appliances and so on.

2, enhance the light resistance of plastic materials

Injection black masterbatch has some light stabilizers, its role is to improve the light resistance of plastic materials, to prevent it from being affected by ultraviolet light and other external factors and lose the original performance, to extend the service life.

3、Improve the performance of plastic raw materials

In addition to changing the color of plastic and enhance light resistance, injection black masterbatches can also improve the performance of plastic raw materials to a certain extent, such as increasing its strength, hardness and so on.

Application Scope

The application range of black masterbatch is very wide, almost all the industries that need to change the color of plastics, increase light resistance or improve the performance of plastics will use it, such as furniture, electrical appliances, automobiles, electronics and so on.

Fourth, the purchase method

1、Focus on the quality of the masterbatch

The quality of injection molding grade black masterbatch is very critical, if you choose the wrong quality masterbatch is not good enough, it will lead to the processed products in terms of appearance, performance and other aspects can not meet the requirements. Therefore, you need to pay attention to the quality of the masterbatch when choosing, as far as possible, choose some well-known brands of products.

2, look at the concentration

Different concentrations of injection molding grade black masterbatches are suitable for different types of processing, users need to choose the corresponding concentration according to their actual needs.

3、Attention to the composition

When buying injection molding grade black masterbatches, you need to carefully check the composition table to determine whether it contains harmful substances, so as not to affect product quality and safety.
