Reworked plastics will enter transition to upgrade centralized period

Policy comes on stage thick and fast related the near future, enough sees decision-making layer silver coin in order to prohibit rubbish enters a country for breach, clear the determination that rectifies second birth to use an industry to machine pollution is very sturdy. Ban dead file according to what Chinese government refers to WTO, useless plastic entrance will be in life source begin to carry out by 2017. Can see at the same time, second birth industry had entered executive phase after the adjustment of relevant policy 2017, so second half of the year will be the collect metaphase that company transition upgrades this year.

Awkward ground forces in company transition

At present country recovers the system still is perfected not quite, short-term country supply has frequent promotion hard, because this long-term home reworked plastics is supplied,still appear relatively nervous. But, although virgin material is in,pull continuously go up, but crude price is at present low, major variety still can have reworked plastics ceiling pressure. Here so the circumstance falls, prospective enterprise has 3 development way. The first, be defined to be economy of environmental protection industry, loop as renewable resources industry, those who have actual strength is medium large company perfects all sorts of environmental protection formalities and equipment investment, the probability of the person that future of this part company becomes an industry to lead is great. The 2nd, partial abroad supplies chamber of commerce to will live kind of reworked plastics, treatment produces second birth particle, reexport reachs our country. The 3rd, domestic part is large manufacturing company, move is produced to abroad, especially the southeast Asia state that has favourable policy with our country, after place digests partial grain supply of goods reimport arrives home.

On policy turning point, second birth enterprise needs to maintain reason, avoid by all means is eager to making bigger hold dish fluctuant. Jin Lian starts proposal business, defend good oneself old client above all, in goods little state of affairs falls can purchase merchandise on hand to be produced in order to manage downstream company from circumjacent area appropriately, avoid the prediction of a person’s luck in a given year that later period client estimates. Next, in policy window period, proposal company discretion is wait-and-see local policy is fluctuant direction, plan ahead of schedule good later period does dish of way. The 3rd, below environmental protection high pressure, production of later period standardization will become the safeguard that second birth industry survives, because this industry all should supply,complete ring reviews the case such as formalities, updating equipment.

China reclaims dimensions of reproduction course of study already very big, downstream application is rich, technology of a lot of domains is banner. Our country is plastic reclaim processing has two kinds of cases: One kind is located in world advanced level, one kind is small mill, best circumstance and the poorest condition coexist. Onefold dimension does not spend policy to be able to be solved this. Reclaim the industry is giant industry, how very good reclaim use need time and innovation. Right amount consumption is must, reclaiming is a link only. The change of the concept is wanting to consider to reclaim at zoology design, it is dweller classification not only, it is the change of whole society system.

ABS resinous is the biggest applied domain depends on auto industry

Light quantify, the trend that with model Dai Gang has made automobile industry develop. And in automobile industry, what use at most on the car is plastic it is Abs colophony.

ABS colophony is the graft copolymer that points to polybutadiene balata and monomer styrene and propylene nitrile, among them A represents propylene nitrile, b represents butadiene, s represents styrene. ABS has the characteristic of a variety of polymer, it is a kind of function admirable thermoplastic plastic, use extensively at auto industry, mechanical industry, appearance instrument industry.

Be opposite to satisfy different domain the diverse demand of ABS colophony function, people deserves to compare through adjusting condition of aggregate means, craft, monomer and the element such as the structural parameter of balata, make diversification of ABS resinous breed. ABS colophony fights impact strength to be able to be divided by its pound for freeboard model, high impact, in concussion etc, by its processing means can be divided for inject, crowded piece, pressure delay, vacuum, blow the grade such as model, according to its utility and function characteristic but farther fractionize is general, heat-resisting, eletroplate, flame retardant, transparent, crowded board, 10 breed such as tubal material, among them general-purpose size of market of colophony of inject class ABS is the largest.

ABS resinous is the biggest applied domain is auto industry.

Car dashboard is the main function on the car with garnish, if use armor plate to do, not only cost is high, and still need a course to cut, more than 10 working procedure such as punch, bore, spray paint, and will make with ABS colophony, need to note model or blow model to be able to shape only.

The car is plastic one of difficult point that turn are automobile body shell plating is plastic change. Automobile body shell plating includes around dashboard, clapboard and face plate to wait, its material dosage is the biggest, and requirement material has impact resistance, hear resistance and tigidity. The alloy with ABS colophony and plastic project has these property, can use the plank outside making automobile body to expect.

Car interior trim having main effect to the comfortable sex of the car and security. The plaque inside contemporary car shapes for whole mostly, the exterior is luxurious, choose ABS colophony commonly.

Master these skills, reclaim divisional mixing plastic waste product is difficult problem no longer!

As the swift and violent development of plastic industry, and the constant growth of plastic rubbish, useless old plastic second birth uses a trade increasingly arisen. But because plastic breed is various, applied field is extensive, reclaiming so in the process, what very much different sort reachs color is plastic was mixed one case. The plastic function of different breed and treatment condition are different, the to treatment and application impact after mixing is very big, be in so useless old plastic reclaim undertake in the process grading it is indispensable link.

One, grading purpose

Reclaim there basically is 3 on plastic mart big grading demand:

1. Eliminate is plastic medium metallic;

2. To different color plastic undertake classified;

3. Of divisional and different sort plastic.

2, grading method

Current, useless old plastic and grading normally cent is mixed for handiwork mechanical and grading two kinds. Preliminary and grading basically choose vibrating separator, turn beat, magnetic force is grading machine, wind-force is grading depart of machine; material can use all sorts of material to pledge grading equipment and device, include density, electrostatic, difference in temperature, infrared ray, optical camera and X- ray divide into equal parts to choose equipment.

1. Handiwork is grading

Hand workpoint is chosen even if be in through will be being mixed artificially useless plastic the impurity in, and the plastic division of different breed is separate. Take time of this kind of method is arduous, efficiency is low, but investment is small, easy begin, the operation is agile. Hand workpoint chooses measure to be as follows:

① eliminate metal and metalloid impurity, the useless plastic products that eliminate quality drops badly.

② presses goods first, if the goods such as filmy, bottle, cup, leftover material undertakes classified, classify different plastic breed according to differentiating a law again.

③ mixes the useless old plastic products of afore-mentioned classification by color depth again quality is grading.

2. Mechanical and grading

Can pass magnetic separation, density grading, centrifugal depart, floatation depart, wind screens electrostatic and grading, grading, infrared ray grading, take a picture grading with difference in temperature grading etc the method is grading. Infrared ray and take a picture grading, also but attributive smooth credit picks a way, be in recent years achievement of digital technology development is in useless plastic reclaim the new application in second birth.

① magnetic separation

Magnetic separation is the method that uses metalloid of iron of magnetic body depart, main purpose is eliminate interfuse is abandoned old plastic the metal such as medium iron and steel is drossy foreign matter, because these are finely,steel iron filings uses manual and grading method eliminate not easily.

② density is grading

Density is grading it is to use different and plastic have different density this one property has grading method, specific means is will jumbly abandon old plastic in be being put into some kind to have the solution of certain density, next the basis is useless old plastic the condition of ups and downs in this solution will undertake grading. Density is grading methodological advantage is simple and easy and feasible, should choose to make up a kind only or a few kinds of solution can have large quantities of amounts grading, and the man minute that avoided loaded down with trivial details chooses; the plastic density that its defect is some sort is very adjacent, accordingly, the detached thing that should achieve tall purity is more difficult.

3. Photoelectricity is grading

This law is to use different sort plastic different to the absorptivity of X ray undertake depart, do not contact, do not destroy plastic products itself, mobile edge is detached by the side of content be detectinged. Differ according to ray action mechanism, smooth credit chooses a law to be able to be divided for X ray depart and fluorescent X ray depart. X ray depart is will projectile X ray change becomes telegraphic name, judge should the plastic products of purify, with compress air to blow its fall undertake depart. Depart of fluorescent X ray is the fluorescent X line that by illuminate X ray thing be detectinged produces, via prismatic and junior travel the ration of bases is judged.

4. Colour separation process

This method is the technology that has depart according to colour, it is to make be detected the color of content adopts several filter look implement hind, be worth each different brightness conversion into electric current and with this in group, combination of color identifying device and material depart device, classics optics discerns plastic bottle after the color that wait, blast blows discolor bottle, this law basically applies at the plastic products of color existence difference.

5. Infrared ray is grading

Infrared ray is grading can divide for close infra-red and grading with infrared ray grading. Close infra-red and grading principle is to use irradiation of close infrared ray by grading the material when content is presented character those who go out is different absorb degree to undertake grading. Close infra-red and grading the sorting that can be used at plastic products.

The principle with grading infrared ray is the identifying that the object presents to issue different reflection character to undertake an object with visible light inside the infra-red wavelengh limits of make choice of. Infrared ray applies at plastic grading, can distinguish 6 kinds plastic, include PET, HDPE, LDPE, PVC, PS, PP, energy standard rate can be amounted to 100% .

6. Groovy wind-force is grading

Groovy wind-force is grading be will classics those who smash is plastic put in grading the eject inside device, wind from transverse or converse inbreathe, use different and plastic have grading method to the obstruction of air current and self-prossessed join forces difference. The degree of finish as a result of the granuality after smashing can affect grading result, the granuality degree of finish after so this law asks to smash is even, and granuality degree of finish is even the main factor that degree is effect of influence selection by winnowing or wind. In addition this law also can be used at grading and plastic in the cobble of interfuse and sand, but reach fractional figure approximately to density irregular plastic and detached effect is poorer.

7. Wind- driven table is grading

Wind- driven table is grading it is wind- driven and grading special kind, its principle is to use the vibration of bed face and ascendant air air current to make grain presses density statified. Particular procedure is from poriferous vibration bed below blows ascendant air to flow, the particle size distribution with bead big or old way is in density lower level, and the particle size distribution with bead small or small way is in density superstratum, below the attrition strength effect in oscillatory acceleration and bed underside, lower level heavy grain moves to declining oscillatory bed upside; is contrary, the attrition force between heavy grain of superstratum light grain and lower level is small, motion arrives a side with oscillatory inferior bed, make thereby both get grading.

8. Electrostatic and grading

Electrostatic and grading it is to use all sorts of plastic and different triboelectricity function to have grading method. The polarity when different and plastic attrition is electrified is decided by live performance. Use electrostatic undertake grading, the useless plastic need to a variety of lump for many times grading, because every pass the voltage of preelection set,can divide only single out a kind plastic.

9. Difference in temperature is grading

Difference in temperature is grading it is to use plastic material to have grading method to the sensitivity of temperature, have microtherm and high temperature different approach.

Microtherm is fragile change grading the law is to use all sorts of plastic have those who differ is fragile change temperature to have grading method.

High temperature granule is grading and plastic granule can happen to change below constant temperature, because,this is plastic lift along with temperature, drawing function and percentage elongation raise the appearance of generation, but different plastic granule changes function to also differ, use this character to undertake plastic grading. Plastic granule changes character to be able to classify as follows:

① can the plastic material that microtherm granule turns includes PE, PP and epispastic PS to wait.

② can the plastic material of microtherm pulverization has PVDC.

③ can the plastic material that high temperature granule turns includes PVC of PET, horniness and plating aluminous film.

④ high temperature also cannot the plastic material that granule turns has hot solid sex plastic.
