塑料袋縫合強(qiáng)度的要求及預(yù)防老化措施

塑料袋縫合強(qiáng)度的要求
Requirements for stitching strength of plastic bags
濟(jì)南塑料袋在制作時(shí)如果是選用新舊質(zhì)料配混時(shí),要特別注意混合的均勻性,而在縫合的時(shí)分,關(guān)于強(qiáng)度也是有嚴(yán)格要求。無強(qiáng)度要求的編織袋上口鎖邊一周,針距可密,線可細(xì)。關(guān)于濟(jì)南塑料袋主體銜接部的抗拉強(qiáng)度,要求有需要到達(dá)基本強(qiáng)度的67%以上,底部銜接部的抗拉強(qiáng)度有需要到達(dá)基本強(qiáng)度的42%以上。
When making plastic bags in Jinan, if new and old materials are used for mixing, special attention should be paid to the uniformity of the mixing, and there are strict requirements for strength during stitching. The upper edge of the woven bag without strength requirements is locked for one week, and the needle spacing can be dense and the thread can be fine. Regarding the tensile strength of the main connection part of Jinan plastic bags, it is required to reach over 67% of the basic strength, and the tensile strength of the bottom connection part needs to reach over 42% of the basic strength.
其實(shí)影響塑料袋縫合強(qiáng)度的主要因素包含縫合線的品種和類型,針距巨細(xì),線跡,卷邊或者邊縫合線到袋邊的尺度,熱切和冷切方法等。
In fact, the main factors that affect the stitching strength of plastic bags include the variety and type of stitching thread, needle pitch, stitching, the scale of the curled or edge stitching thread to the bag edge, hot and cold cutting methods, and so on.
塑料袋老化的預(yù)防措施
Preventive measures for aging of plastic bags
1.塑料袋在自然環(huán)境下即在陽光直射的條件下,一周后其強(qiáng)度下降25%,兩周后會(huì)下降40%,基本上已不能運(yùn)用。也就是說塑料袋的貯存保管問題非常重要。
1. In natural environments, such as direct sunlight, the strength of plastic bags decreases by 25% after one week and by 40% after two weeks, making them basically unusable. That is to say, the storage and storage of plastic bags are very important.

2.在塑料包裝水泥后放在露天環(huán)境受陽光直射,強(qiáng)度會(huì)急劇下降。
2. After plastic packaging of cement, placing it in an open environment under direct sunlight will cause a sharp decrease in strength.
3.塑料袋貯運(yùn)過程中溫度過高(集裝箱運(yùn)送)或遇到雨淋,都會(huì)導(dǎo)致其強(qiáng)度下降,然后達(dá)不到維護(hù)內(nèi)裝物品的質(zhì)量要求。
3. During the storage and transportation process of plastic bags, if the temperature is too high (transported in containers) or if they encounter rain, their strength will decrease, and they will not meet the quality requirements for maintaining the contents.
4.再產(chǎn)生料的過多參加也是加強(qiáng)塑料袋老化的原因之一。
Excessive participation in the production of raw materials is also one of the reasons for strengthening the aging of plastic bags.
