From cutting nine grains to the cold time, it is 20 seconds or less. When the cooling time is too long and excessively cooled, and thus the nine degrees reached after the package is manufactured, the stability of the shape of the package is lowered, and the cooling time is better, and The best is 15 seconds or less. In addition, for the adhesion of the borrowing, to improve the ease of taking the bag from the bag storage box, or to reduce the problem of clogging the pipe program in order to reduce the drying procedure or the weighing procedure sticking to each other, the cooling is more or better. 7 seconds or more, and further or more. In order to increase the fusion strength between the nine particles by setting the nine-sheet temperature during the production of the package to improve the temperature, the temperature of the cooling water is preferably 1 °C or 20 °C or higher. In addition, in order to reduce the bag take-up when the bag is taken out of the bag storage case by reducing the storage bag, the cooling water temperature is better and more, for example, due to a nine-plug process problem during the drying process or the weighing process. The best is 3 5 ° C or lower. Although the nine-grain line is cooled in cooling water, it can be moved. An example of a state in which the nine particles can be left to stand is the state in the nine grains. Alternatively, move the state of the flow of cooling water in the nine-state instance. As for the method of separating the nine particles from the cooling water while cooling, the nine particles are strongly fused by the particles. In addition, the change period is 18 seconds or less. The period during which the package is taken down is, for example, because the nine-part is preferably 5 seconds. More preferably, the 10-second surface temperature is higher than the specified package. The shape is stable, and it is better that the adhesion between them is easy, or for the particles to adhere to each other and the plug is 40 ° C or lower, the nine particles are allowed to stand or are contained in the cooling bath for the nine particles. The system and tube can be any known method including separation and centrifugation separated by a sieve of -9 - 201236841. After the separation of 2 1 , the nine pellets were subjected to a drying treatment in a gas stream. The gas flow temperature is 5 ° C or higher and 40 ° C or lower. When the temperature of the gas stream is too low, the nine particles are excessively cooled, and thus the fusion strength between the nine particles obtained after the package is produced is lowered, so that the stability of the shape of the bag is lowered. In order to further improve the stability of the shape of the bag, the temperature of the gas stream is preferably 1 〇 ° C or higher. Moreover, when the temperature of the air stream is too high, the nine particles are insufficiently cooled, and thus the ease of taking the bag when the bag is taken out of the bag storage case is lowered, or during the drying process or the weighing process, for example, due to nine mutual The possibility of sticking and blocking the tube program is likely to increase. In addition, in order to improve the ease of taking the bag when the bag is taken out of the bag storage case, or to further reduce the problem of clogging the pipe program during the drying process or the weighing process, for example, due to the adhesion of nine particles to each other, the air flow temperature is higher. The best is 3 5 °c or lower. As for the method for performing the drying treatment, a method of blowing nine particles with air in a blast dryer may be utilized, or the air may be allowed to flow in the tube and the nine particles may be used in the tube together with the air passing through the tube. The method of flow. After drying the nine particles in the air stream, weighed to obtain the required amount of nine particles, and the nine particles obtained by the weighing were compression-molded for a period of time, wherein the average elapsed time after the separation of the nine particles obtained by the weighing was 3 0 seconds or more and 1 〇〇 second or less, thereby obtaining a rubber bag. When the average elapsed time is too long, the nine particles are excessively cooled, and thus the fusion strength between the nine particles obtained after the package is manufactured is lowered, so that the stability of the shape of the package is lowered. The average elapsed time is preferably 90 seconds or less, and more preferably 80 seconds or less. Or, when the average elapsed time is too short, the nine grains

-10- S 201236841 的熱不足以擴散至該九粒表面,且因此在製造包中所獲得 之該九粒表面溫度未增加,以致該九粒之間的融合強度被 降低以及包的形狀之穩定性被降低。該平均經過時間較佳 的是45秒或更多,且更佳的是60或更多。模製壓力較佳 的是50 kg/cm2至150 kg/cm2 ’且模製時間較佳的是5秒 至20秒。 這時,將經稱重取得之九粒分離後的平均經過時間( 由待加以壓縮成型之全部九粒間取得),爲藉由分離裝置 將該九粒與該冷卻水分開至經過壓縮成型製造包的經過時 間之平均。在介於九粒分離與壓縮成型之間有複數個程序 的情況中,該平均經過時間係藉由取得在各個程序中各九 粒的貯留時間並加總貯留時間來計算。舉例而言,運輸程 序中的貯留時間係以各九粒移動速度爲基礎而取得。又, 在稱重程序中的貯留時間係以成型循環時間及九粒饋入速 度爲基礎而取得。 在成型中,大於所需包的包可藉由切割該較大的包而 成型,以獲得所需包。此外,爲保護該包的表面,可將經 成型包的表面以膜包覆。 根據本發明所製造之橡膠包可適於應用在包括車輛輪 胎及密封材料之各種用途。 根據本發明所製造之橡膠包的形狀穩定性佳。此外, 在乾燥程序中及稱重程序中極少造成程序問題。利用於本 發明之適用方法不包括將九粒壓縮成型前加熱九粒之步驟 ,且此方法在成本上有極佳優勢。 -11 - 201236841 圖1顯示本發明中利用之方法實施例的實例槪要。將 相當於原料的橡膠饋入擠壓機(1)、經過具有孔洞之模 具擠壓出、並於製粒機(2)中切割及冷卻,藉此獲得九 粒。將所獲得之九粒立即自製粒機排出並經由管(9 )與 冷卻水一起被運至分離裝置(3)。將在分離裝置中與冷 卻水分開之九粒通過鼓風乾燥機(4)並於壓縮成型機(5 )中成型爲包。 圖2顯示本發明中利用之方法實施例的另一實例槪要 。此實例從原料饋入至擠壓機(1)達至運送該九粒至分 離裝置(3)與圖1中所示相同。自該分離裝置(3)排出 之九粒掉入垂直管(12),同時暴露於空氣、於管(13) 中與藉由鼓風機(6)所發送之空氣一起被運送至經過旋 風器(7)及垂直管(14),至壓縮成型機(5),它們在 此成型爲包。 實例1 將苯乙烯丁二烯聚合物橡膠饋入擠壓機、以旋轉切割 刀片切割、並將該生成物以冷卻水冷卻’由此獲得九粒。 調整擠壓機圓筒的溫度’以使在模具中已熔融橡膠的溫度 爲1 3 0 °C。該冷卻水的溫度約爲3 0 °C。取出經此獲得之十 個九粒,且結果每一個九粒的平均質量爲〇·43 g。 將所獲得之九粒立即自製粒機排出並與管中流動冷卻 水運至分離裝置。自切割橡膠至輸入九粒至分離裝置中的 冷卻時間約爲1 4秒。The heat of -10-S 201236841 is not sufficient to diffuse to the nine surface, and thus the nine surface temperatures obtained in the manufacturing package are not increased, so that the fusion strength between the nine particles is lowered and the shape of the package is stabilized. Sex is reduced. The average elapsed time is preferably 45 seconds or more, and more preferably 60 or more. The molding pressure is preferably from 50 kg/cm2 to 150 kg/cm2' and the molding time is preferably from 5 seconds to 20 seconds. At this time, the average elapsed time after separation of the nine particles obtained by weighing (taken from all nine particles to be compression-molded) is to separate the nine particles from the cooling water to a compression-molded manufacturing package by a separating device. The average of the elapsed time. In the case where there are a plurality of procedures between the nine separation and the compression molding, the average elapsed time is calculated by taking the storage time of each of the nine particles in each program and adding the storage time. For example, the storage time in the transportation process is based on nine movement speeds. Further, the storage time in the weighing procedure was obtained based on the molding cycle time and the nine-feed speed. In forming, a package larger than the desired package can be formed by cutting the larger package to obtain the desired package. Further, to protect the surface of the bag, the surface of the formed bag may be coated with a film. The rubber bag manufactured in accordance with the present invention can be suitably used in a variety of applications including vehicle tires and sealing materials. The rubber bag manufactured according to the present invention has a good shape stability. In addition, there are very few procedural problems in the drying process and in the weighing procedure. The method applicable to the present invention does not include the step of heating nine particles before compression molding, and this method has an excellent cost advantage. -11 - 201236841 Figure 1 shows an example of an embodiment of a method utilized in the present invention. The rubber equivalent to the raw material was fed into the extruder (1), extruded through a mold having a hole, and cut and cooled in a granulator (2), thereby obtaining nine particles. The obtained nine instant granules were discharged and transported to the separation device (3) via a tube (9) together with cooling water. The nine particles separated from the cooling water in the separating device were passed through a blast dryer (4) and molded into a bag in a compression molding machine (5). Fig. 2 shows another example of an embodiment of the method utilized in the present invention. This example is fed from the feedstock to the extruder (1) until the transport of the nine pellets to the separation device (3) is the same as that shown in Figure 1. The nine particles discharged from the separating device (3) fall into the vertical tube (12) while being exposed to the air, and are transported in the tube (13) together with the air sent by the blower (6) to the cyclone (7). And vertical tubes (14) to compression molding machines (5) where they are formed into a package. Example 1 A styrene butadiene polymer rubber was fed into an extruder, cut with a rotary cutting blade, and the resultant was cooled with cooling water. Thus, nine particles were obtained. The temperature of the extruder cylinder was adjusted so that the temperature of the molten rubber in the mold was 130 °C. The temperature of the cooling water is about 30 °C. Ten nine particles obtained by this were taken out, and the average mass of each of the nine particles was 〇·43 g. The nine instant granules obtained were discharged and transported to the separation device with flowing cooling water in the tubes. The cooling time from cutting the rubber to inputting nine to the separation device is about 14 seconds.
