PET是乳白色或淺黃色、高度結(jié)品的聚合物,表面平滑有光澤。在較寬的溫度范圍內(nèi)具有優(yōu)良的物理機(jī)械性能,使用溫度可達(dá)120℃,電絕緣性優(yōu)良,甚至在高溫高頻下,其電性能仍較好,但耐電暈性較差,耐蠕變性,耐疲勞性,耐摩擦性、尺寸穩(wěn)定性都很好。PET 有酯鍵,在強(qiáng)酸、強(qiáng)堿和水蒸汽作用下會(huì)發(fā)生分觸,耐有機(jī)溶劑、耐候性好。缺點(diǎn)是結(jié)晶速率少,成型加工困難,模塑溫度高,生產(chǎn)周期長,沖擊性能差。一般通過增強(qiáng)、填充、共混等方法改進(jìn)其加工性和物性,以玻璃纖維增強(qiáng),提高樹脂剛性、耐熱性、耐藥品性、電氣性能和耐候性。但仍需改進(jìn)結(jié)晶速度慢的弊病,可以采取添加型核劑和結(jié)晶促進(jìn)劑等手段。加阻燃劑和防燃劑滴落劑可改進(jìn) PET阻燃性和自熄性。 為改進(jìn)PET性能,PET可與PC、彈性體、PBT、PS類、ABS、PA形成合金。 PET(增強(qiáng)PET)主要采取注射成型法加工,其他方法還有擠出、吹塑、涂覆和焊接、封接、機(jī)加工、真空鍍膜等二次加工方法。成型前須充分干燥。 主要應(yīng)用為電子電器方面有:電氣插座、口連接器、電飯煲把手、電視偏向軛,端子臺(tái),斷電器外殼、開關(guān)、馬達(dá)風(fēng)扇外殼、儀表機(jī)械零件、點(diǎn)鈔機(jī)零件、電熨斗、電磁灶烤爐的配件;汽車工業(yè)中的流量控制閥、化油器蓋、車窗控制器、腳踏變速器、配電盤罩;機(jī)械工業(yè)齒輪、葉片、皮帶輪、泵零件、另外還有輪椅車體及輪子、燈罩外殼、照明器外殼、排水管接頭、拉鏈、鐘表零件、噴霧器部件。 我公司代理美國伊斯曼透明的共聚聚酯 (PETG, PCTA,PCTG)。 該產(chǎn)品具有高透明度、高光澤率、高韌性、耐沖擊、彎曲,的耐化學(xué)腐蝕性能,良好的抗刮傷性,良好的加工性,并符合 FDA認(rèn)證。 用于: 1、化妝品包裝容器、醫(yī)藥包裝及醫(yī)療透明配件 2、吹瓶 3、透明管材及異型材、薄膜、片材、板材,供應(yīng)上海遠(yuǎn)紡的PET CB602 低粘,符合FDA認(rèn)證,可用于吹瓶,有意者請(qǐng)前來商談!

儀器介紹RA-620高精度自動(dòng)折光儀/糖度計(jì) Refractometer/Brix Meter
RA-620高精度自動(dòng)折光儀/糖度計(jì) 術(shù)語和定義:
光線自一種透明介質(zhì)進(jìn)入另一種透明介質(zhì)時(shí),產(chǎn)生折光現(xiàn)象,這種現(xiàn)象是由于光線在各種不同的介質(zhì)中進(jìn)行的速度不同造成的。折光率系指光
線在空氣中傳播的速度與在其它物質(zhì)中傳播速度之比值。
折光率refractive index 在鈉光譜D線、20℃的條件下,空氣中的光速與被測(cè)物中的光速的比值或光自空氣通過被測(cè)物時(shí)的入射角的正弦與折射角的正弦的比值。
RA-620高精度自動(dòng)折光儀/糖度計(jì) 方法原理:
當(dāng)光從折光率為n的被測(cè)物質(zhì)進(jìn)入折光率為N的棱鏡時(shí),入射角為i,折射角為r,則: Sin i / Sin r = N / n………..(1) 在折射儀中,入射角I = 90°,代人式(1)得: 1 / Sin r = N / n n = N ? Sin r……………….(2) 棱鏡的折光率N為已知值,則通過測(cè)量折射角r即可求出被測(cè)物質(zhì)的折光率n。
