(2)將鋼邊橡膠止水帶需要熔接的兩端頭搭接處中間留下長(zhǎng)30~40mm的空間用于接頭熔接、干凈生膠片的連接。如果生膠片占有灰塵須用干凈布擦干凈灰塵或用打磨機(jī)將生膠片表面打磨干凈后才能使用。
(2) Leave a space of 30-40 mm in the middle of the overlap between the two ends of the steel-edged rubber water stop belt which need to be welded for the joint welding and the connection of clean raw film. If the raw film occupies dust, it must be cleaned with a clean cloth or polished with a grinder to clean the surface of the raw film before it can be used.
(9)開(kāi)模檢查。如檢查發(fā)現(xiàn)生膠片熔合不飽滿(mǎn),存在缺膠、開(kāi)裂、分層等現(xiàn)象需返回至步驟1重新開(kāi)始鋼板橡膠止水帶的端頭熱熔接。如檢查發(fā)現(xiàn)橡膠止水帶接頭處熔合飽滿(mǎn),不脫膠,可以進(jìn)行下一步驟。
(3)在已打磨光滑的鋼邊兩面涂刷橡膠與金屬粘結(jié)劑。
(3) Rubber and bl binders are applied on both sides of polished smooth steel.
(4)在加工打磨鋼板橡膠止水帶連接端頭的同時(shí)預(yù)熱橡膠止水帶的熔接模具好,預(yù)熱時(shí)間按電熱絲的發(fā)熱功率約在30分鐘。目的是將模具溫度控制在140~150℃度之間。當(dāng)溫度計(jì)顯示模具溫度已到140~150℃即可進(jìn)行后續(xù)步驟。
(4) The welding die of the preheated rubber water stop is good while grinding the connection end of the steel plate rubber water stop. The preheating time is about 30 minutes according to the heating power of the electric heater wire. The aim is to control the temperature of the die between 140 and 150 degrees C. When the thermometer shows that the temperature of the die has reached 140-150 C, the follow-up steps can be carried out.
(5)把需要熔接鋼邊橡膠止水帶兩端頭按步驟2搭接放入橡膠熔接模具底模的中間,連接處放滿(mǎn)生膠片。
(5) Place the two ends of the rubber sealing tape with steel edge to be welded in the middle of the bottom die of the rubber welding die according to step 2, and fill the connection with raw film.
(6)按模具的對(duì)中孔洞,輕輕放置熔接模具的頂模。在安放模具頂模的過(guò)程中要避免生膠片和熔接端頭的跑位,如果過(guò)程中鋼邊橡膠止水帶需熔接的兩端頭跑位,需重復(fù)此步驟,確保熔接兩端頭的正確位置。
(6) Place the top die of the welding die gently according to the middle hole of the die. In the process of placing the top die of the die, the running of raw film and fusion end should be avoided. If the two ends of the steel-edged rubber water stop need to be welded in the process, this step should be repeated to ensure the correct bbbbbbbb of the fusion ends.
(7)用千斤頂將安放好的頂模具加壓。此步驟注意的是:第一次千斤頂加壓壓力不要過(guò)大大,加壓至模具頂模和底模之間距離在2cm左右。待熔接鋼邊橡膠止水帶的生膠片硫化一段時(shí)間,約5~10分鐘后再進(jìn)行千斤頂?shù)亩渭訅骸?/span>
(7) Pressure the mounted jacking die with a jack. This step is to note that the pressure of the first jack should not be too large, and the distance between the pressure and the top and bottom dies of the die should be about 2 cm. The raw rubber sheet of the welded steel edge rubber water stop tape is vulcanized for a period of time, and the second pressure of the jack is applied after about 5 to 10 minutes.
(8)千斤頂二次加壓是將模具縫隙加壓至設(shè)計(jì)鋼邊橡膠止水帶斷面。加壓后,保持模具溫度在140~150℃之間,時(shí)間約20~30分鐘即可開(kāi)模。
(8) The second pressurization of the jack is to press the die gap to the section of the rubber water stop at the design steel edge. After pressing, the mould temperature is kept between 140 and 150 degrees C, and the mould can be opened in about 20 to 30 minutes.
(10)將已熔接好的鋼邊止水帶的鋼邊連接處用釘子或鋼絲連接好,或?qū)⒋私宇^連接處的鋼邊焊接牢固。
(10) Connect the steel edge joints of the welded steel edge water stop strip with nails or steel wires, or weld the steel edges of the joints firmly.
