pe塑料袋在我們的生活中經(jīng)常使用。它們分為許多不同的類(lèi)型，適用于不同的領(lǐng)域。在我們的日常生活中，我們經(jīng)常使用PE塑料袋。pe是聚乙烯的簡(jiǎn)稱(chēng)，聚乙烯是由乙烯聚合而成的熱塑性樹(shù)脂。它具有許多優(yōu)點(diǎn)，可用于服裝、箱包、電子產(chǎn)品等包裝。這主要是由體育的突出特點(diǎn)決定的。PE塑料袋的特點(diǎn)是什么?下面是PE塑料袋廠(chǎng)家的介紹。

Pe plastic bags are often used in our life. They are divided into many different types and are applicable to different fields. In our daily life, we often use PE plastic bags. Pe is the abbreviation of polyethylene, which is a thermoplastic resin polymerized from ethylene. It has many advantages, can be used for clothing, bags, electronic products and other packaging. This is mainly determined by the outstanding characteristics of sports. What are the characteristics of PE plastic bags? The following is the introduction of PE plastic bag manufacturers.

 

優(yōu)良的耐腐蝕性和電氣絕緣(特別是高頻絕緣)。可采用氯化、化學(xué)交聯(lián)、輻射交聯(lián)等方法改性。低壓聚乙烯具有熔點(diǎn)高、硬度高、強(qiáng)度大、吸水率低、電性能好、抗輻*性能好等特點(diǎn);高壓聚乙烯具有良好的柔韌性、伸長(zhǎng)率、沖擊強(qiáng)度和滲透性;UHMWPE具有較高的沖擊強(qiáng)度、抗疲*性能和耐磨性。低壓聚乙烯適用于制造耐腐蝕零件和絕緣零件;高壓聚乙烯適用于制膜;高分子量聚乙烯(UHMWPE)適用于減震、耐磨、傳動(dòng)部件。

 

Excellent corrosion resistance and electrical insulation (especially high-frequency insulation). It can be modified by chlorination, chemical crosslinking, radiation crosslinking, etc. Low pressure polyethylene has the characteristics of high melting point, high hardness, high strength, low water absorption, good electrical properties, and good radiation resistance; High pressure polyethylene has good flexibility, elongation, impact strength and permeability; UHMWPE has high impact strength, fatigue resistance and wear resistance. Low pressure polyethylene is suitable for manufacturing corrosion resistant parts and insulating parts; High pressure polyethylene is suitable for film making; High molecular weight polyethylene (UHMWPE) is suitable for shock absorption, wear resistance and transmission parts.

造型特點(diǎn):1。結(jié)晶物料吸濕性小，不需要充分干燥，流動(dòng)性好，對(duì)壓力敏銳。適用于成型時(shí)采用高壓注射，料溫均勻，充型速度快，保壓充分。不宜采用直澆口，以防不均勻收縮，增加內(nèi)應(yīng)力。注意澆口位置的選擇，防止縮孔變形。2. 收縮幅度和收縮值大，方向性明顯，易變形和翹曲。冷卻速度要慢，模具要設(shè)有冷料袋，還有冷卻系統(tǒng)。3.加熱時(shí)間不宜過(guò)長(zhǎng)，否則會(huì)發(fā)生分解。4. 當(dāng)軟塑件有較淺的側(cè)槽時(shí)，可以用力脫模。5. 熔體可能斷裂，不建議與溶劑接觸，防止開(kāi)裂。

 

Modeling features: 1. Crystalline material has low moisture absorption, does not need to be fully dried, has good fluidity and is sensitive to pressure. It is suitable for high-pressure injection during molding, with uniform material temperature, fast filling speed and sufficient pressure holding. The straight gate should not be used to prevent uneven shrinkage and increase internal stress. Pay attention to the selection of gate location to prevent shrinkage deformation. 2. Large shrinkage amplitude and value, obvious directivity, easy to deform and warp. The cooling speed should be slow. The mold should be equipped with a cold material bag and a cooling system. 3. The heating time should not be too long, or decomposition will occur. 4. When the soft plastic parts have shallow side grooves, force demoulding is allowed. 5. The melt may break, so it is not recommended to contact with the solvent to prevent cracking.
