Ujuzi wa Bodi ya Aluminium -Tabia za Bodi ya Aluminium -plastiki na Mchakato wa Uzalishaji I. Tabia za Bodi za Aluminium -plastic:

Sahani ya aluminium -plastiki ni aina mpya ya nyenzo za mapambo. Ikilinganishwa na vifaa vingine vya mapambo, ina ukuu mwingi usio na usawa. Kwa upande mmoja, bodi za plastiki za aluminium ni nyenzo ya mchanganyiko, ambayo inaweza kupata mali mpya ambayo vifaa vingi vya asili hupatikana kupitia mchanganyiko.

Kwa upande mwingine, bodi za aluminium -plastiki ni bidhaa ya hali ya juu. Ikiwa ni uzalishaji au matumizi, ina maudhui ya juu ya kiufundi.

Michakato mingi ya hali ya juu hutumiwa katika uzalishaji, kama vile teknolojia ya mipako ya rolling na teknolojia inayoendelea ya mafuta, kuhakikisha uchezaji kamili wa utendaji wa nyenzo.

Vipengele kuu vya bodi za plastiki za aluminium zinaonyeshwa katika mambo yafuatayo.

1. Ubora mdogo:

Sahani za aluminium -plastiki zinaundwa na vifaa vya msingi vya plastiki na aluminium na wiani, kwa hivyo ikilinganishwa na alumini (au metali zingine) na ugumu sawa au unene, ubora wao ni mdogo kuliko glasi na jiwe. Ubora ni bora zaidi. Ni ndogo sana.

2. Ugumu mzuri:

Bodi ya aluminium -plastiki hutumia kwa busara kanuni ya mitambo ya muundo wa chuma, na njaa ya busara huipa mali ya kipekee ya mitambo. Kwa kuongezea, bodi za plastiki za aluminium zinafikia kiwanja chini ya hali ya joto ya juu, na sahani mbili za aluminium za sahani za alumini katika mchakato mzima wa usindikaji ni hakika katika hali ya mvutano, wakati aina ya baridi imepozwa, kwa sababu aluminium ya ulinganifu Bamba na nyenzo za msingi hutolewa kwa kiwango cha contraction, mkazo wa ndani wa bodi ni thabiti na una ugumu mzuri. Ikilinganishwa na sahani za aluminium moja, kikomo chake cha elasticity ni kubwa, sio rahisi kutoa deformation. Katika hali ya asili bila nguvu nyingi za nje, inaweza kudumisha utendaji mzuri wa gorofa kwa muda mrefu.

3. Rangi tajiri na mapambo yenye nguvu:

Kiwango cha bodi ya plastiki ya alumini inaweza kufanywa kuwa rangi tofauti kutekeleza muundo wa muundo ambao unalingana na matumizi yote.

Kwa kuongezea, ili kutumia muundo wa teknolojia ya nakala ya picha, granite, nafaka za kuni, na mifumo ya chuma, hutoa muundo wa muundo na monochrome, muundo wa usahihi na muundo wa hali ya juu. Ubunifu wa rangi na muundo unakutana na uratibu ambao unakidhi mahitaji ya mazingira tofauti, kuwezesha mitindo tofauti ya usanifu kuendana na mazingira, rangi iliyochaguliwa na mazingira ni sawa, na athari ya kisanii ni kamili. Starehe za kuona. Ukuta wa pazia uliopambwa na paneli za plastiki za alumini sio duni kwa ukuta mzuri wa pazia la glasi na ukuta wa kifahari wa pazia la jiwe.

Chini ya jua, kiwango chake ni nzuri na yenye hadhi, na wakati huo huo epuka uchafuzi wa taa.

4. uso wa juu wa uso:

Bodi za aluminium -plastiki hutolewa na michakato inayoendelea ya uzalishaji wa moto na kiwanja. Therefore, compared with a single material metal plate, its surface flatness is high, especially large -sized plates are more obvious. Kwa mapambo ya ujenzi, ina muonekano wa gorofa na gorofa.

5. Uimara mzuri:

Sahani ya aluminium -plastiki hutumia teknolojia ya chuma na ya msingi ya mafuta, ambayo imefungwa kabisa. The surface coatings are selected from different materials according to the different use environment. Generally, three types of coatings are used, namely fluorocarbon coatings, polyester coatings, and acrylic coatings. Carbon coatings have better weather resistance and are mostly used in curtain wall decoration and specific occasions. Test studies have shown that they can be used for more than 20 years in harsh outdoor environments.

6. Good processability:

Aluminum -plastic plates are composed of aluminum and plastic. It is easy to process cutting, punching, digging, and bending. It can be processed with aluminum or woody processing equipment. Therefore, not only can be processed in the production plant, the proposed composite board can be processed on -site.

7. Excellent fire resistance:

In the aluminum -plastic board series, the fire -resistant aluminum plastic board uses a newly developed core material. This core material is filled in the filling feather. Require.

8. Good cost characteristics:

The production of aluminum -plastic boards adopts the continuous heat composite process of pre -coating and the metal/core material. Compared with the general metal veneer, the production efficiency is high and the cost of raw materials is low. It is a material with good cost characteristics.

9. Good environmental coordination:

The aluminum and plastic core in the abandoned aluminum -plastic plate can be used 100%for regeneration, and the environmental load is low.

In addition, the wood -aluminum plastic plate and outdoor decorative aluminum plastic plate uses fluorocarbon coatings. The products have high durability and low daily maintenance costs, reducing the cost of the entire life cycle.

10. Wide use:

Aluminum -plastic panels are cost -effective and widely used. In addition to the decoration of curtain walls, inner and outer walls, hall halls, restaurants, shops, conference rooms, etc., it can also be used for the reconstruction of old buildings. Inner and outer walls, etc.

Second, aluminum -plastic board production process:

There are many production processes of aluminum -plastic plates. The composite process of plastic core board and two -sided aluminum plates can be divided into cold compound legal and hot compound legal; it can also be divided into continuous compound legal and intermittent compound legal.

The process of producing aluminum plastic plates is first to clean aluminum coils. Due to the needs of the production of aluminum coils, the surface is coated with lubricants and anti -oxidants, and some dirt will also be attached during transportation, which will affect its adhesion, so it must be cleaned. After the aluminum coil is cleaned and chemically treated, the surface will produce a dense chemical protective film; this layer of chemical film can improve the antioxidant capacity of aluminum coils and extend the life of the paint film.

The general process of cleaning is as follows: aluminum rolls → spraying abandonment → water washing → neutralization → chemical treatment → water washing → drying → cooling → receiving rolls.

The clean aluminum coil was sent to the coating machine and coated high -performance fluorocarbon resin on the surface of the aluminum coil. The process process is as follows:

Aluminum rolls → feeding → coating fluorocarbon coatings → hot air circulating paint → cooling → covering → cutting → collection.

The panel of the outer wall aluminum plastic plate should be coated with two layers of paint and primer. The surface paint of the outer wall plate is a fluorocarbon resin coating with extremely high weather resistance, that is, polyfront diofluoroethylene (PVDF). Its excellent anti -ultraviolet performance and anti -environmental pollution can keep the protected aluminum coil surface. Essence The surface of the aluminum -plastic composite board can not only have metal colors, but also beautiful marble patterns and colors.

Fluorocarbon coatings usually apply roller coating methods to aluminum coils, and then baked at high temperature to dry it. The equipment is continuous production, first paint paint, then paint paint, and finally coat the coatings. The total thickness of the three layers of paint is 30 μm. Each lacquer needs to be baked for about 60s above 200 ° C to dry it. After the oven is released, it quickly cools through the air -cooled machine.

The inner wall paint can use epoxy resin, polyester resin and acrylic resin. After the paint, top paint, and surface paint are painted, a layer of PE protective film is pasted on the coating layer surface to avoid being scratched during the processing and transportation and installation of the surface coating.

The protective film is self -mucous membrane, and it can be unveiled after installation.

Aluminum coils with fluorocarbon resin can enter the process of compounding with plastic core materials. The plastic core is essentially three layers, the middle is PE plastic, and the two sides are adhesives. PE sheets and adhesives can be produced separately, and can also be produced in three layers of commonly squeezed out.

Karatasi ya tatu -iliyotengenezwa ya archaea/PE/wambiso imejumuishwa na tabaka za juu na za chini za sahani ya alumini. Sahani ya composite aluminium -plastic composite ni sahani ya aluminium 0.15mm pande zote mbili, na safu ya msingi ni 3 hadi 3 ～ 5mm, unene wa jumla ni 4-6mm. Mwishowe kata katika uainishaji wa 1220mm x 2440mm.
