Abstract
The invention belongs to the technical field of polymer packaging materials, and relates to a preparation method of a CLASS 10-1000-level (U.S. federal 209 E standard) clean polyethylene packaging bag. A formula for raw materials comprises LDPE (low-density polyethylene) with a weight percentage of 50-60%, LLDPE (linear low-density polyethylene) with a weight percentage of 35-45% and an opening agent with a weight percentage of 2-8%; the preparation method comprises the following steps: mixing, stirring, heating and dehumidifying the raw materials according to proportions, blow-molding to a barrel-shaped semi-finished product, carrying out dust removal and clean treatment on the semi-finished product in a CLASS 100-level purification room, cutting and sealing in all kinds of sizes according to actual requirements, and carrying out dual-layer closed encapsulation. According to the preparation method provided by the invention, the pollution problem of electronic product components in a transfer process is completely solved, a process for repeatedly cleaning and removing the dust is removed, the cost and the resources are saved, the environmental pollution is reduced, and meanwhile, the additional damage and the reject ratio generated by machines and personnel operations during repeated cleaning and dust removal of the product can be greatly reduced.
Description
Technical field
The invention belongs to polymeric packaging material technical field, relate to a kind of CLASS 10-1000(the United States Federal 209E standard) preparation method of the clean polyethylene packaging bag of level.
Background technology
Manufacture due to electronic product is now more and more small-sized and become more meticulous, and this just requires that product is more and more higher for the requirement of clean level; In addition present electronic product is substantially all be divided into multiplex's section or the dispersion of many producers to be produce, then unified assembling test goes out (as: product of the company such as apple, IBM, Seagate) of finished product, traditional method be will by the parts of each product before carrying out multiplex's section or factory's transhipment in clean mistake, also need the process once cleaning dedusting before transporting to next workshop section or factory-assembled! This is because product component receives pollution in transport process, so the process repeatedly repeating clean dedusting that must carry out.
When clean all inevitably a large amount of use pure water cleaning after carry out hyperthermia drying, also need to use the chemical of a large amount of high pollution to process in cleaning course to some metal, silicon chip product, be want the manufacturing cost of larger production, waste resource, environment is also unavoidably polluted so certainly.
Summary of the invention
The object of the invention is the preparation method proposing the clean polyethylene packaging bag of a kind of CLASS 10-1000 level, described CLASS 10-1000 level is the United States Federal 209E standard.
Main technical schemes of the present invention: the preparation method of the clean polyethylene packaging bag of CLASS 10-1000 level, is characterized in that composition of raw materials: the opening agent of the LDPE of weight percentage 50-60%, the linear LLDPE of weight percentage 35-45%, weight percentage 2-8%; Preparation method is by after said ratio mix and blend, heating, dehumidifying by raw material, be blow molded into barrel shape material work in-process, in CLASS 100 grades of purification rooms, carry out de-dirt and clean process to work in-process, that carries out various size according to actual requirement cuts sealing, and carries out double-layer seal encapsulation.
Usually, in above-mentioned preparation process, a kind of typical composition of raw materials: the opening agent of the LDPE of weight percentage 55%, the linear LLDPE of weight percentage 40%, weight percentage 5%.
Described opening agent known by this field, as amine hydroxybenzene etc.
In preparation process, general control blow moulding machine core temperature is at 135 DEG C---and 160 DEG C, rotating speed: 20-40 revolutions per seconds.
Preparation method of the present invention, to thoroughly solve the pollution problem in electronic product components transport process, eliminate the operation repeating clean dedusting, save cost, resource and reduction for the pollution of environment, also greatly can reduce machine and human users when product repeats clean dedusting and the additional injuries that produces and scrap rate simultaneously.
Product prepared by the inventive method can be widely used in semiconductor crystal wafer, optics, the display of LCD-TFT plane, mobile phone and computer touch display screen, high purity silicon material, computer hard disc, clean working garment cleaning pack afterwards, numerous industry and product needing clean packaging such as the packaging of various dust-free cleaning cloth.
Embodiment
Below in conjunction with embodiment, the inventive method is described in detail.
Embodiment:
The present embodiment is prepared according to following proportioning raw materials, the opening agent of the LDPE of weight percentage 55%, the linear LLDPE of weight percentage 40%, weight percentage 5%.
By raw material by after said ratio mix and blend, heating, dehumidifying, be blow molded into barrel shape material work in-process, in CLASS 100 grades of purification rooms, carry out de-dirt and clean process to work in-process, that carries out various size according to actual requirement cuts sealing, and carries out double-layer seal encapsulation.
In the present embodiment preparation process, control blow moulding machine core temperature and control 150 DEG C ± 10%, rotating speed: 30 revolutions per seconds.
Product prepared by the present embodiment, has following characteristics after tested.
Embodiment sample foreign matter content detected result sees the following form:
Embodiment sample composition is analyzed (according to performance analysis on the file NO.20800020-001 method GC/MS liquid of Seagate) and be the results are shown in following table:
As can be seen from above analytical results, product prepared by the present invention:
1. can be free of in finished product composition and have: all kinds of carcinogens of aminocompound, silicone oil, DOP(), all kinds of heavy metals that meet ROSH standard, the content that falls the end or the content not containing all kinds of charged ion, greatly reduce particular carbon hydrogen compound and corrosive gases.
2. product cleanliness factor: (the removable Grain size controlling of>=0.5um is at≤10pcs/cm can to reach CLASS 10 grade standard
2).
Claims (2)
