升液管涂料產(chǎn)品說(shuō)明：目前為止，升液管試用過(guò)許多替代材料，但由于鑄鐵的**度，經(jīng)久耐用且價(jià)廉，始終是受表睞的材料之一。其缺點(diǎn)主要是由于鑄鐵界面與鋁液接觸，熔融鋁合金中易吸入鐵雜質(zhì)。產(chǎn)品應(yīng)用：低壓鑄造機(jī)鑄鐵升液管用。產(chǎn)品優(yōu)點(diǎn)：TL976的作用就是提供一有效載體來(lái)保護(hù)鑄鐵表面，同時(shí)，產(chǎn)品中特點(diǎn)的粘結(jié)體系具有持久的粘結(jié)效果防止腐蝕。其配方系特點(diǎn)設(shè)計(jì)，**于保護(hù)低壓鑄造機(jī)上使用的鑄鐵升液管，具有減少溫降、減少熔體中鐵的吸入、使用方便等特點(diǎn)。該涂料供給狀態(tài)即可使用。使用說(shuō)明：被涂覆的鑄件升液管必須事先清潔干燥，除去油、油膩或任何脫落的顆粒，內(nèi)壁用TL976灌入孔內(nèi)保證其全部涂覆，升液管外側(cè)可采用刷涂TL976可即取即用，但如若認(rèn)為有必要可稍作稀釋。儲(chǔ)存：保存于干燥陰涼處。

升液管本實(shí)用新型涉及一種升液管，具體的說(shuō)涉及一種鋁合金車(chē)輪低壓鑄造使用的升液管。由于鋁合金車(chē)輪是汽車(chē)上**為重要的外觀件及**件之一，因此各主機(jī)廠都對(duì)車(chē)輪供貨提出了嚴(yán)格的要求，無(wú)論是尺寸、外觀還是性能均要滿足一定的設(shè)計(jì)標(biāo)準(zhǔn)。目前，世界上約80%的鋁合金車(chē)輪生產(chǎn)采用低壓鑄造成形工藝，該技術(shù)屬于底部中心澆注形式，保溫爐內(nèi)的高溫鋁液通過(guò)升液管道進(jìn)入模具型腔，并在模具及外部冷卻的共同作用下凝固成形，**終得到合格的毛坯鑄件。在整個(gè)鑄造系統(tǒng)中，升液管作為連接保溫爐與模具的通道，在車(chē)輪生產(chǎn)中的作用舉足輕重。依據(jù)生產(chǎn)經(jīng)驗(yàn)，一個(gè)質(zhì)量的升液管應(yīng)該具備以下特點(diǎn):良好的保溫性，比較大限度的減少鋁液在進(jìn)入型腔前的熱量損失，以防止發(fā)生鋁液凍死事情；具備較強(qiáng)的鋁液過(guò)濾能力，不可以將保溫爐內(nèi)的氧化膜等雜質(zhì)帶入模具型腔，形成鑄件夾渣廢品；具有良好的耐腐蝕性、耐高溫性，保證升液管有較長(zhǎng)的使用壽命；價(jià)格經(jīng)濟(jì)，節(jié)約生產(chǎn)成本。然而，現(xiàn)有技術(shù)中的升液管很難兼具上述幾種特質(zhì)，也因此會(huì)造成生產(chǎn)中工藝控制困難，鑄件夾渣缺點(diǎn)頻發(fā)，產(chǎn)品外觀不達(dá)標(biāo)導(dǎo)致客戶抱怨等等問(wèn)題，這些問(wèn)題都嚴(yán)重的制約著車(chē)輪的成品率，并提高了企業(yè)的制造成本。江西氮化硅升液管價(jià)格</p><p
