PVC塑料造粒機(jī)
純凈的聚氯乙烯，只是一種白色的粉未，也就是說(shuō)它只是一種高分子樹(shù)脂，不能用于直接加工產(chǎn)品；由于合成工藝路線(xiàn)的不同，這種樹(shù)脂粉一般分為兩類(lèi)：一種是疏松型樹(shù)脂，另一種是緊密型樹(shù)脂。我們常用的聚氯乙烯膠料都是顆粒狀的，它是多組份的塑料，除了前面講的聚氯乙烯樹(shù)脂粉以外，還必須加入增塑劑增加它的流動(dòng)性，加入穩(wěn)定劑提高它的熱穩(wěn)定性，加入潤(rùn)滑劑提高它的脫模性，以及填料，著色劑，偶聯(lián)劑等；因?yàn)楦鹘M份的含量不同，就形成了各種機(jī)械性能差異很大的不同硬度的PVC顆粒；它一般用IP度數(shù)表示；PVC顆粒大體分為：軟質(zhì)PVC，硬質(zhì)PVC。 外觀(guān) 因PVC膠料所含的組份不同，它的外觀(guān)差異很大。有的透明如玻璃，也有不透明的；有的非常柔軟，耐折迭，有類(lèi)橡膠彈性；也有硬質(zhì)的，象ABS，機(jī)械性能優(yōu)良，可以做工程材料。大部分的PVC有輕微毒性，但不致于一接觸就能中毒；也有食品級(jí)的PVC膠顆粒。燃燒特征 PVC難燃，離火即滅；但燃燒時(shí)，火焰上端呈黃色，下端呈綠色（綠色是氯離子的特有色譜），冒白色煙霧（白色煙霧是HCL氣體與水結(jié)合的產(chǎn)物）；燃燒時(shí)，膠料發(fā)軟，同時(shí)，發(fā)出刺激性的氣味。
PVC plastic granulator
Pure polyvinyl chloride is only a white powder, which means it is a polymer resin and cannot be used for direct processing of products.Due to the different synthetic process routes, this kind of tree powder is generally divided into two types: one is loose resin and the other is compact resin.We often use the PVC plastic material is granular, it is more plastic components, in addition to speak in front of the PVC tree powder, must also join plasticizer increase its liquidity, add stabilizer to improve its thermal stability, add lubricant to improve its release, as well as the packing, colorants, coupling agent, etc.;Because the content of each component is different, the PVC granules with different hardness are bed.It is generally expressed by IP number;PVC particles are generally divided into: soft PVC, hard PVC.The appearance is very different due to the different components of PVC.Some are glassy and opaque;Some of them are very soft, folding, and rubber elastic;Also has the hard, elephant ABS, the mechanical property is good, can do the engineering material.Most PVC is mildly toxic, but can be toxic without contact;There are also food grade PVC glue particles.The burning characteristic PVC is difficult to ignite, and the fire is extinguished;But when it burns, the upper end of the flame is yellow, and the lower end is green (green is the characteristic color of chloride ion), and white smoke (white smoke is the product of the combination of HCL gas and water).When burned, the gel is soft, and at the same time, it emits a pungent odor, like hydrochloric acid.
