收縮率熱塑性塑料成型收縮的形式及計(jì)算如前所述,影響熱塑性塑料成型收縮的因素如下:1.1塑料品種熱塑性塑料成型過程中由于還存在結(jié)晶化形起的體積變化,內(nèi)應(yīng)力強(qiáng),凍結(jié)在塑件內(nèi)的殘余應(yīng)力大,分子取向性強(qiáng)等因素,因此與熱固性塑料相比則收縮率較大,收縮率范圍寬、方向性明顯,另外成型后的收縮、退火或調(diào)濕處理后的收縮率一般也都比熱固性塑料大。件特性成型時(shí)熔融料與型腔表面接觸外層立即冷卻形成低密度的固態(tài)外殼。
工程塑料液下泵機(jī)械密封中還存在設(shè)計(jì)、選擇、安裝等不夠合理的地方。液下泵彈簧壓縮量一定要按規(guī)定進(jìn)行,不允許有過大或過小的現(xiàn)象,誤差2mm,壓縮量過大增加端面比壓,摩擦熱量過多,造成液下泵密封面熱變形和加速端面磨損,壓縮量過小動(dòng)靜環(huán)端面比壓不足,則不能密封。安裝液下泵動(dòng)環(huán)密封圈的軸(或軸套)端面及安裝靜環(huán)密封圈的密封壓蓋(或殼體)的端面應(yīng)倒角并修光,以免裝配時(shí)碰傷動(dòng)靜環(huán)密封圈。液下泵機(jī)械密封本身是一種要求較高的精密部件,對(duì)設(shè)計(jì)、機(jī)械加工、裝配質(zhì)量都有很高的要求。

R29屬于碳?xì)渲评鋭?對(duì)臭氧層完全沒有破壞,并且溫室效應(yīng)亦非常小,屬于zui環(huán)保的制冷劑之一。主要用于替代R2R52制冷劑使用在低溫制冷設(shè)備中;由于R29制冷劑易燃易爆,通常只用于充液量較少的低溫制冷設(shè)備中,或者作為低溫混配冷媒的一種組分;R29與傳統(tǒng)的潤滑油兼容。高純級(jí)R29用作感溫工質(zhì);優(yōu)級(jí)和一級(jí)R29可用作制冷劑替代R2R52,與原系統(tǒng)和潤滑油兼容,用于空調(diào)、熱泵空調(diào)、家用空調(diào)和其它小型制冷設(shè)備。

其特點(diǎn)是蒸發(fā)潛熱大,冷卻能力強(qiáng);流動(dòng)性能好,輸送壓力低,耗電量低,負(fù)載溫度回升速度慢。與各種壓縮機(jī)潤滑油兼容。在常溫下為無色氣體,在自身壓力下為無色透明液體。R6a主要用于替換R12制冷劑,現(xiàn)在多用于家用冰箱設(shè)備。R6a同樣是yiranqiti,與空氣混合能形成性混合物,遇熱源和明火有燃燒的危險(xiǎn)。與氧化劑接觸猛烈反應(yīng)。其蒸氣比空氣重,能在較低處擴(kuò)散到相當(dāng)遠(yuǎn)的地方,遇火源會(huì)著火回燃。R717(氨)R717(氨)制冷劑,氨是中溫制冷劑,純氨對(duì)潤滑油無不良影響,但有水分時(shí),會(huì)降低冷凍油的潤滑作用,在氨制冷系統(tǒng)中對(duì)管道及閥件均不采用銅和銅合金。
