Begin to realize high-powered PLA to machine from the a bit

New PLA colophony (the product that is like NatureWorks company) it is crystallization product commonly, be to moisture content by male dry before leaving manufacturing unit 400 Ppm. 2.

If receive,box and liner are packed when PLA complete nondestructive, the male dry workload that needs is few, but still need to undertake male dry. If filmy liner already was opened, undertake male dry with respect to need. 3.

New colophony already crystallized commonly, in order to facilitate efficient male dry. Not crystal PLA rises to generation of the meeting when 140 ℃ to change in temperature stick, agglomerate. 4.

Smash PLA or reclaim PLA may be crystallization or blame crystallization, shape by transparent heat reject of product, clip or shedding the fragment that delays sheet treatment is high blame crystallization, the fragment that machines by drawing film or drawing sheet is crystallization and the mixture that are not crystallization material, and the fragment that machines by fiber is high crystallization. 5.

Before treatment, answer to undertake checking with colophony supplier, test and verify will throw the resinous condition in machining equipment, can undertake accordingly planning to craft thereby. 6.

If use speed to cross high duct road to carry, in effort makings of bead of the colophony in carrying a process produces degradation extremely likely. PLA colophony can form fine streamline in pipeline system interior, general generation is in bent housing place and the place that rely on bent housing closely. 7.

The discharge rate with reasonable tank car should be to make an appointment with 20 thousand pound hourly, be in data speed limit minutely 5000 inches or lower. The hand uses tank car driver operation car fan and a powerful person, the setting carries a system to finish the discharge of car. When 4 " model when duct line and car conveyor combination are used, if set fan speed and pressure quite high, it is OK to not be in inside the time to 1 hour discharge drops raw material of 40 thousand pound. Fine pink or streamline can arise every time when with this kind configuration is operated. Unit position 8.

A treatment trade is pushed in PLA, good position can improve the moving performance of equipment. When choosing the equipment that squeezes a product line place to need, undertake program and equipment itself to usable floor area it is coequal and important to purchase. 9.

In working procedure initiative end, material is carried and the position of keep in storage is the first step that requires a consideration. Chosen material carries the position and extruder to ought to be coordinated closely in the position in product line, make raw material can be carried inside reasonable distance thereby. 10.

Allocating material to prepare the space of device is the focal point that the next requires to pay close attention to. Be like source of extruder park material around, criterion male dry machine, crystallizer, disintegrator should be located in recent area as far as possible with mixture equipment. these machines arrangement is near extruder, operation personnel preparation and all operation of moving product line are met very convenient. The material handling system that effort carries a system to expect to affidavit of extruder feed in raw material is every plastic the main component that pushs a system. When handling PLA, carry a system to a few need to notice to commonly used effort. 11.

Use vacuum to carry craft to carry data in product line interior as far as possible. Use vacuum to carry a system, once the system produces leak, can be a few indoor air only by inspiratory duct in the line. If be carried in high pressure,leak happens in the system, medium dust meets the system fly off from leakage point point, deposit is producing a workshop. 12.

Use what design appropriately to carry dynamical plant, move in order to drive air in the system. Choose air-blower of proper the type that decide a look, make air-blower moves with proper rotate speed, produce formulary throughput. In make choice of this device after, its apply to individual duct diameter only, produce specific colophony to carry rate inside the system thereby. Although a lot of people think new bead makings does not have dirt, but actual in, put always in data processing system in the fine pink of certain amount, undertake administrative to the system so, reduce fine pink to generate as far as possible. The air current that chooses air-blower of proper the type that decide a look to adopt a system with careful control through choosing is the basic approach that solves this one problem. Through restricting top speed 5000 feet / cent (F/M) (make an appointment with 1000m/min) , with respect to the degradation phenomenon that can reduce effort to carry the data in the process. 13.

In the rate that should keep of the system enough into makings end, be in thereby of the system feed makings end reliably inspiratory colophony. What the starting speed that restricts 3500 F/M can make sure PLA carries a system is normal move. What sheet of PLA of system of craft water refrigeration squeezes a craft to need system of craft water refrigeration to assure extruder and male dry opportunity is normal move. 14.

Have on extruder into system of makings area water-cooling, and the cooling device of system of machine hydraulic pressure. It is OK that wind refrigeration snail is answered to be in charge of in these devices and male dry machine move in device of a water tower. Nextpage15.

Sheet squeezes the polishing roller that when going out, contacts with hot colophony to need cooling water to achieve enough sheet cooling rate. These requirements are the basis of demand of cooling water of firm product line. Product line of sheet of mixture operation PLA can produce much waste material in moving process, of these flotsam time use pair of sheet quality and product cost control crucial. 16.

Running single-track system (only an extruder supplies resin to modular head) when, measure the 40%-50% that is total output commonly for the flotsam into the system afresh. 17.

Raw material of mixture PLA of accurate, even ground can ensure the success of downstream working procedure. Inspect makes product, batch mixer needs will virgin material and one plant or of a variety of origin smash makings is even mix. The lubricious material that wants with place of batch mixer interfuse even and other technology additive. When the operation of PLA crystallizer is machining PLA colophony, the raw material that extruder place uses is in before fusing must male dry. If insufficient male the mechanical function that can drop finished product. 18.

Before male dry, PLA colophony should undertake crystallization, with assuring traditional hopper male dry function runs system of craft male dry normally 19.

PLA resinous craft male dry is the raw material is the most crucial step in planning a course. To make good sheet, the standard of craft male dry is to should achieve 250PPM or lower moisture content. 20.

Be in only specific temperature, up to mark of the ability below condition of corresponding processing time and air quality asks. If did not satisfy an either in needed male dry element to nod, or did not maintain resinous male dry is spent, product quality is met unqualified. To PLA, male dry is undesirable can make product degradation. 21.

When treatment business is preparing and squeezing a PLA colophony, answer very careful, because fundamental colophony is damaged,after is not reversible commonly. 22.

The equipment of male dry PLA is to have small craft temperature the dehumidify hopper of optional function male dry machine. In male dry PLA from time to tome 4 main factors. The first is to need enough air current to convey heat energy colophony, undertake enough gas is exchanged, take away all moisture. The 2nd element is the airy that enters hopper of craft male dry male dry is spent or dew point. Industrial standard is dew point - 40 ℃ . The 3rd element is temperature, of PLA applicable male dry temperature is 150 ℃ - 190 ℃ . We are recommended use can come true sufficient the lowermost temperature of male dry, it is 150 ℃ commonly - 160 ℃ . The 4th is the most main factor in male dry craft, namely male dry hopper. Male dry hopper looks very simple, likewise a few very main factors need to notice, include to choose appropriate hopper cubage. Small hopper, stock male dry is not worth the likelihood; Cross big hopper, stock grows too in the retention period inside makings canister again. Treatment hopper design considers to heat up even male airy distributings, shed male dry efficiency in order to realize the most significant thing. If 4 element satisfy above completely, can join crystallization colophony, undertake beforehand male dry, move push a system, realize successful production. Switch arrives from BOPP product line the change of BOPLA product line as traditional market structure, the product line that partial company hopes to use a convention realizes the likelihood the treatment of PLA. Original product line may machine PET, also may be treatment PP. In August 2010, the whole world the banner supplier of the dual system that pull film Br ü Ckner Servtec (the following abbreviation: Bulukena) a BOPP of help Italy produces what business completed a product line to transform installation. A when global BOPP precedes the company combines company of industry of unripe Taghleef yield business and Bulukena to care about big profit to Taghleef company existing product line undertook transforming, use at producing BOPLA. Bulukena designed special distribution, offerred existing push a system, stream delay device and TDO the main component that these needing that transform, and the 0 component that peripheral equipment transforms place to need. To be used with the most efficient way all these new package, still upgrade technology control system transform the type that uses latest technology. In Bulukena the comprehensive test that has on company lab product line confirmed the configuration data of collateral working procedure. The installation that Bulukena still is in charge of supervising direct product line to transform and debug a process. New product line is in on August 18, 2010 put into production, a week after begins successfully to have industrialized production. The S-GRAN-HD that NGR develops reclaims what device can realize PLA is high-powered reclaim. Efficient biology polymer reclaims the system is the closest, NGR company developed a kind successfully to answer the new technology with midwifery plastic content effectively. Of biology polymer it is difficult to reclaim to be thought to face huge normally, what a lot of experts think to be made by biology material even is plastic cannot reclaim, the latest technology of NGR company proves this one understanding is wrong. NGR company from at the beginning with respect to with a view to " one footwork craft " , use this technology, plastic reclaiming high temperature is not experienced in the process. The most important is, the biology that is worth to high price is plastic (biology polymer) reclaim, do not experience high temperature to have more important sense. Because,this is by but raw material of second birth plant makes " natural and plastic " production cost should compare the product that makes by crude oil tall 2 to 3 times. In addition, typical NGR " one footwork craft " can effect is tall, cost of the electric power in moving process is inferior also be one of its window. Because raw material cost is high, investment redound time is very short, and, the waste capacity of the generation in producing a course is few. NGR company CEO Josef Hochreiter thinks this craft has the land of use force greatly: "In production process, strong cut an operation to be able to produce mass-produced waste material. Our target is to should let the material of these high value can reclaim, in returning manufacturing process directly. " should plan not to apply to the live thing that already sold to consumer however plastic: Because biology is plastic those who have degradation of easy live thing is characteristic, connect regular meeting compost to handle. NGR discovery, data of the biology inside global limits appears to grow considerably, compare with the plastic photograph that is based on crude oil, be born in the future content is plastic the meeting is more and more important. Europe and United States obtained great progress in respect of biology polymer technology at present, the potential market of NGR technology is in possible focal point these areas. Josef Hochreiter estimation, because demand increases ceaselessly, before 2012, it is with the global demand of the equipment that at smashing these high price are worth material annual 100: "Accordingly, the yield that we predict our firm can utilization rate will taller. " the client part that uses first manufacturing unit of these new technologies to had been in Europe and United States moves. Germany blew model film manufacturer to undertake successfully already trying moving: 20%-50% reclaims material can be added in new material, do not have bad influence to quality character. After foreword craft, if presswork, the layer closes and rush cut also did not produce any problems. Before reclaiming, flotsam is OK keep in storage is as long as 6 months, function won't have a loss. CNC Milling CNC Machining
