產品分類 : 橡膠浸漬機
Condom manufacturing machine process Collecting the raw materials Rubber latex is obtained from the milky fluid produced by various tropical plants. Latex is actually an emulsion or dispersion of tiny rubber particles in water, and ingredients added to the latex must be able to attach to the rubber particles during compounding. Compounding Next, chemical additives are mixed to form a paste. This paste is then blended with the liquid latex in a process called compounding. Storage The latex and chemical compound is then unloaded into drums for storage, where it remains for approximately seven days. During this period, vulcanization chemically strengthens the bonds of the rubber. The storage time also allows any air, which might have been trapped in the mixture during compounding, to escape. Dipping The compound is then added to the dipping or condom-forming machine. The dipping machine is a long, hooded machine approximately 100 feet (30.5 m) in length. Thick tempered glass rods move along a closed belt between two circular gears. The belt drags the rods, which are called mandrels, through a series of dips into the latex compound. The mandrels rotate to spread the latex evenly. Several coats are required to build the condom to its required thickness. Between each dip, the latex is hot air dried. After the final dipping and drying, the condoms automatically roll off the mandrels. A machine shapes and trims the ring of latex at the base of each condom. Tumbling Next, the condoms are put in a tumbling machine, where they are coated with talc or another similar powder to prevent the rubber from sticking to itself. Testing After a curing period of several days, the condoms are sampled by batch and tested for leaks and strength. The first such test is the inflation test, in which the condom is filled with air until it bursts. Condoms are required to stretch beyond 1.5 cubic feet, about the size of a watermelon, before bursting. This test is considered most important because the elasticity of the condom keeps it from tearing during inter-course. In the water-leakage test, the condom is filled with 10 ounces (300 ml) of water and inspected for pin-sized holes by rolling it along blotter paper. Condoms are also tested electronically. This involves mounting each condom on a charged stainless steel mandrel. The mandrel is passed over by a soft, conductive brush. If pin holes are present, a circuit will be established with the mandrel, and the machine will automatically reject the condom. Packaging Condoms that have successfully passed these tests are rolled by a machine. Rolling the condom makes it easier to package and use. Lubricant and spermicide may be applied by a metering pump just before the top wrap is added in the foiling process.
Hyperform® HPN® 715 改性助劑
產品分類 : 添加劑
Hyperform® HPN® 715可以在聚丙烯(PP)均聚物和抗冲共聚物中使用,可以在保持良好抗衝擊性的同時,在樹脂中產生最高剛性。通過提高熱變形温度,它還具有卓越的熱稳定性。 不但具有更快的成核速度,促使注塑成型提高生產效率,而且經Hyperform HPN 715改性的聚丙烯(PP)可以僅使用較小用量,降低填料要求,從而提高設計自由度,减輕重量,縮减材料成本。利用本改性助劑,改良後的聚丙烯(PP)更適用於注塑加工。 由於Hyperform HPN 715賦予聚丙烯更高的熱變形温度(HDT),該類材料的典型用途變得廣泛而多樣,其中包括汽車组件和部件,以及家用電器零件、工業包裝、花園家具、水桶和微波容器。
