1.注塑過（guò）程中使用更多純（chún）樹脂
1. Use more pure resin during injection molding
在許多（duō）塑料的注塑加工中，尤其是在（zài）諸如聚氯乙烯（xī），苯乙烯，聚乙酸乙酯和（hé）丙烯酸酯之類的塑（sù）料中，痕量的殘留單體會產（chǎn）生難聞的氣味（wèi）。使用單體殘留非（fēi）常困（kùn）難的樹脂就足夠了,這些氣（qì）味。如（rú）果使用本來就無味的樹脂，則效果會很差。
In the injection molding of many plastics, especially in plastics such as polyvinyl chloride, styrene, polyvinyl acetate and acrylate, trace residual monomers will produce unpleasant smell. It is sufficient to use a resin with very difficult monomer residue to eliminate these odors. If you use an already tasteless resin, the effect will be very poor.
2.注塑（sù）加工改變添加劑
2. Change additives in injection molding
用於生產聚氨酯泡（pào）沫的叔胺（àn）催（cuī）化劑（jì）通常會產生非（fēi）常（cháng）微弱的氣味，此外，它還會（huì）在（zài）汽車的內窗玻璃上形成霧氣。該問題的方（fāng）法是找到這些胺的替代物，其中一種措施是使用多羥基化合物，剩餘的羥基化合物不僅是聚氨酯（zhǐ）分子鏈的組成部分，因此它們還具有催化活性。一些多羥基化合物也可以代替叔胺催化劑的（de）一半，因此（cǐ）生成（chéng）的產品散發（fā）出的臭味比那還少。
The tertiary amine catalyst used to produce polyurethane foam usually produces very faint odors. In addition, it also forms fog on the inner windows of cars. The way to solve this problem is to find substitutes for these amines. One measure is to use polyhydroxy compounds. The remaining hydroxyl compounds are not only components of polyurethane molecular chain, so they also have catalytic activity. Some polyhydroxy compounds can also replace half of the tertiary amine catalyst, so the resulting products emit less odor than that.
PVC擠出或壓延中使用的苯酚穩定劑通常被高（gāo）氣味的鋅穩定劑代替。由（yóu）於其高（gāo）氣味和低霧化特性，熱穩定劑辛酸錫（xī）在汽車PVC中也很常見（jiàn）。在（zài）產品中，植物提取油（如芥酸和油酸）比胺潤滑劑（用於聚烯烴和苯乙烯食品包裝中）的氣味要高得多材料）由動物提取（qǔ）油製成。
Phenol stabilizer used in PVC extrusion or calendering is usually replaced by high odor zinc stabilizer. Due to its high odor and low atomization characteristics, heat stabilizer tin octanoate is also very common in automotive PVC. In products, vegetable extracted oils (such as erucic acid and oleic acid) have a much higher odor than amine lubricants (used in polyolefin and styrene food packaging). Materials) are made of animal extracted oils.
3.注塑加工吸附劑
3. Injection molding adsorbent
如果聚合物中填充有少（shǎo）量沸石（一種鋁矽酸鹽吸附劑），它將起到材料異味的作用,沸石具有大量的圓盤，可以捕（bǔ）獲帶有（yǒu）氣味的小氣體分子。該分子吸附劑已成（chéng）功應（yīng）用（yòng）於聚烯烴擠（jǐ）出管，注塑加工和擠出吹塑容器，隔離（lí）包裝材料，擠出包裝材料和密封件。分子吸附粉末也可以（yǐ）作為吸濕劑添加到塑料中,除去除水（shuǐ）蒸氣（qì）外，該水蒸氣還（hái）將有助（zhù）於塑料製品的氣味。
If the polymer is filled with a small amount of zeolite (an aluminosilicate adsorbent), it will eliminate the peculiar smell of the material. Zeolite has a large number of discs, which can capture small gas molecules with odor. The molecular adsorbent has been successfully applied to polyolefin extrusion tubes, injection molding and extrusion blow molding containers, isolation packaging materials, extrusion packaging materials and seals. Molecular adsorption powder can also be added to plastics as a hygroscopic agent. In addition to water vapor, the water vapor will also contribute to the odor of plastic products.
