干混 |
可以使用低剪切混合器(如滾筒式混合器或錐形混合器)將片狀或母料與預干燥和冷(<40°C)塑料顆?;虮∑苫?/font> |
可以在低于50℃的高剪切混合器中與其他材料混合。 |
|
在單螺桿擠出機,雙螺桿擠出機或knea上添加THYOSIL CXP 5045 |
如(1)中制備的干混物可以體積計量,重量分析或直接進(jìn)料到擠出機的混合區 |
Twin-Screw Feeders Non intermeshing spiral screw with 6mm clearance between the screw and the tube recommended. Eliminate agglomeration at the throat or feed zone by maintaining tube temperature below 80°C. 重量進(jìn)料計量系統可用于將平行流中的薄片或母粒產(chǎn)品形式直接進(jìn)入擠出機的進(jìn)料區。 特別推薦皮帶和圓盤(pán)給料機。 雙螺桿給料機推薦使用螺桿和管之間6mm間隙的非嚙合螺旋螺桿。 通過(guò)保持管溫度低于80℃消除在喉部或進(jìn)料區聚集 |
|
.體積給料機:建議使用良好校準的變送量小于0.5%的進(jìn)料器。 螺桿和管之間的間隙為3至5毫米也需要減少細粉。 通過(guò)保持管溫度低于80℃消除在喉部或進(jìn)料區聚集。 |
|
除了細粉末之外,側進(jìn)料系統和其它類(lèi)型的強制加料擠出機可以與所有固體產(chǎn)品形式一起使用,以在下游進(jìn)料產(chǎn)品。 以下參考下游飼料給出停留時(shí)間建議。 |
|
任何形式的擴鏈劑直接重量/體積添加到塑料熔體可以通過(guò)任何合適的下游排氣口或脫氣口進(jìn)行。 |
|
在注塑成型和組合注塑吹塑成型操作期間添加 |
|
|
|
Twin-Screw no intermeshing spiral screw with 6mm clearance between the screw and the tube recommended. 單獨的重量計量計量系統可用于將THYOSIL CXP5045的母料與塑料直接進(jìn)入注射成型機的進(jìn)料區。 特別推薦皮帶和圓盤(pán)給料機。 雙螺桿無(wú)嚙合螺旋螺釘,螺桿和管之間6mm間隙推薦。 |

Procedure步驟 |
Pre-drying 預干燥 |
Pre-dry the base plastic at manufacturer’s recommended conditions. 推薦下預干燥基礎塑料。 |
In some instances small amounts of THYOSIL CXP5045 can be compensated for poor or incomplete drying, thus bringing robustness and saving to your operations. 在某些情況下,添加少量的THYOSIL CXP5045可以補償不良或不完全的干燥,從而為您的操作帶來(lái)方便和節省操作。 |
|
Hygroscopicity: there is no evidence of bulk absorption of moisture over extended periods of time for THYOSIL CXP5045. At normal conditions of temperature and relative humidity its surface reaches equilibrium saturation through adsorption at less than 0,25% of moisture. At extreme conditions its surface reaches equilibrium saturation at less than 0,50% of moisture. This means that THYOSIL CXP5045 can generally be processed without any drying, even after long exposure to drastic conditions bringing no more than 5ppm moisture per every 0,1% used. 吸濕性:THYOSIL CXP5045在長(cháng)時(shí)間內沒(méi)有大量吸收水分的跡象。在正常的溫度和相對濕度條件下,其表面通過(guò)吸附小于0.25%的水分達到平衡飽和度。 在極端條件下其表面水分,在小于0.50%達到平衡飽和。這意味著(zhù)即使經(jīng)過(guò)長(cháng)時(shí)間暴露于劇烈的條件下,THYOSIL CXP5045通常也可以進(jìn)行加工處理,每0.1%使用不超過(guò)5ppm的水分。 |
|
Ins systems where moisture sensitivity is extreme, THYOSIL CXP5045 can be dried in a desiccant dryer ant 30°C for 1 hour, prior to use. 在潮濕敏感度極高的系統中,THYOSIL CXP5045可以在干燥劑干燥器中于30℃ 干燥1小時(shí),然后再使用。 |
|
Extruder/injection molder temperature profile 擠出機/注塑機溫度曲線(xiàn) |
Where feeding solid THYOSIL CXP5045 in any solid form, except masterbatch, into the first zone of the extruder or infection molder, we recommend to operate this zone at 20°C to 40 °C lower temperature than normal. This will prevent early melting and agglomeration of the additive. 在將固體形式除母粒之外的固體THYOSIL CXP5045進(jìn)入擠出機或感染模塑機的第一區域內,建議比常溫低 ,在20℃至40℃的溫度下操作該區域。 這將防止添加劑的早期熔化和附聚。 |
All other zones should employ normal processing condition as recommended by the plastic’s manufacturer. 所有其他區域應采用塑料制造商推薦的正常加工條件。 |
|
Additive thermal stability 添加劑熱穩定性 |
THYOSIL CXP5045 is thermally stable up to 320°C. Above this temperature additive decomposition may occur. THYOSIL CXP5045在320°C以下是熱穩定的。 高于此溫度可能會(huì )發(fā)生分解。 |
Residence time 停留時(shí)間 |
THYOSIL CXP5045 reacts quickly. Its reaction will be over 99% complete if at least 3 min residence time is provided at 200°C in a well-mixed system. Alternatively, 45 sec residence time at 280°C will provide 99% completion. THYOSIL CXP5045快速反應。 如果在200℃下在充分混合的系統中至少提供3分鐘的停留時(shí)間,其反應將達到99%以上。 或者,在280℃下停留時(shí)間為45秒將完成99%。 |
These limits accommodate most extrusion and injection molding processed for the recommended thermoplastics and applications. 這些限制適用于為推薦的熱塑性塑料和應用而加工的大多數擠出和注塑。 |
|
For use in polymerization reactors where residence time is over 5 minutes, see recommendations in section “Methods of Dosage”. 用于停留時(shí)間超過(guò)5分鐘的聚合反應釜中,請參見(jiàn)“劑量方法”一節中的建議。 |
- THYOSIL CXP5045 should not be processed at temperatures higher than 320°C
- THYOSILCXP5045不應在高于320°C的加工溫度。
Extruder pressure effects擠出機壓力效應
The use of THYOSIL CXP5045 in reactive extrusion or reactive injection molding operations increases significantly the molecular weight, this lead to an increase in melt viscosity, which in turn raises the pressure observed in the equipment.
The table below exemplifies the large increases in die pressure that are observed in PET as THYOSIL CXP5045 is added to a large extruder. Similar increases are expected in other plastics.
在反應性擠出或反應性注射成型工具中使用THYOSIL CXP5045顯著(zhù)增加了分子量,這導致熔體粘度的增加,從而提高了設備中觀(guān)察到的壓力。下表列舉了將THYOSIL CXP5045加入到大型擠出機中時(shí)在PET中觀(guān)察到的模具壓力的大幅增加。 預計其他塑料類(lèi)似增長(cháng)。

The pressure increases both at the die and in front screen system may be 25% to 100% higher than typical operating pressure for higher usage levels. Instantaneous pressure variations and spikes are due to large instantaneous changes in melt viscosity. At constant temperature, changes in melt viscosity are often due to variable feed rate and/or poor mixing.
在模具和前屏幕系統中的壓力增加可以比用于較高使用水平的典型操作壓力高25%至100%。瞬時(shí)壓力變化和尖峰是由于熔體粘度的瞬間變化很大。 在恒定溫度下,熔體粘度的變化通常是由于可變的進(jìn)料速率和/或混合不良。

Troubleshooting故障排除
- In case of unexpected high pressure:Ø如出現意想不到的高壓:
- Decrease the feed rate of THYOSIL CXP5045.降低THYOSIL CXP5045的進(jìn)料速度。
- Decrease the RPM. This decrease pressure on single screw extruders and flood-fed twin-screw extruders, and will decrease hating on starve-fed twin-screw extruders.)
降低轉速。 這對單螺桿擠出機和擠壓雙螺桿擠出機的壓力降低,并且將減少對供給雙螺桿擠出機的不適
- Slowly increase the temperature, starting from the die and then from the last to the zone.
緩慢升高溫度,從模頭開(kāi)始,然后從最后到達區域。
- With pressure under control, increase the THYOSIL CXP5045 feed slowly.

Troubleshooting故障排除
- In case of unexpected high pressure:Ø如出現意想不到的高壓:
- Decrease the feed rate of THYOSIL CXP5045.降低THYOSIL CXP5045的進(jìn)料速度。
- Decrease the RPM. This decrease pressure on single screw extruders and flood-fed twin-screw extruders, and will decrease hating on starve-fed twin-screw extruders.)
降低轉速。 這對單螺桿擠出機和擠壓雙螺桿擠出機的壓力降低,并且將減少對供給雙螺桿擠出機的不適
- Slowly increase the temperature, starting from the die and then from the last to the zone.
緩慢升高溫度,從模頭開(kāi)始,然后從最后到達區域。
- With pressure under control, increase the THYOSIL CXP5045 feed slowly.
在控制壓力下,慢慢增加THYOSIL CXP 5045進(jìn)料。
- For steady operation follow recommendations given in the section “extruder pressure effects”
為了穩定運行,請參閱“擠出機壓力效應”一節中給出的建議
