The advantages and disadvantages of aluminum -plastic panel curtain wall

Hlcaluminium -aluminium composite Panels Manufacturers

In recent years, with the rapid economic development, the decoration standards of the construction units have also risen. Some newer building exterior walls are becoming increasingly popular with some high -end decoration materials. It seems that it is not enough to display its grade without the curtain wall. A few years ago, it was popular glass and natural stone curtain walls.

At present, it is mainly used for some public buildings, and there are also a few residential areas that are used for high -end routes. Because the use of aluminum -plastic composite boards for high -rise buildings has always been left -handed, aluminum -plastic composite board has become the latest hot topic in the industry since its birth. One opinion is that the aluminum -plastic composite board curtain wall should be used less or cautious.

The use of aluminum -plastic composite plates (ie, aluminum -plastic plates) as high -rise buildings will become "air killer" or "invisible killer", which is extremely dangerous. Those who hold this opinion believe that its disadvantages are four: First, the structure of the aluminum -plastic composite board is generally three layers, and the two sides of the outside are 0.1 to 0.5mm thick aluminum layer. Polyethylene) and other polymer materials are bonded with tree vinegar glue. The core materials and glue contain toxic ingredients, and the fire prevention, weather resistance, durability, anti -aging and other properties are poor. It will release a poisonous gas that is harmful to human health; the second is that the compound strength is not high, and it is easy to break when the corner curved surface. When the partial heating is heated, the core material will expand and cause the surface aluminum plate to deform and fall off. In addition, its thermal expansion coefficient is generally larger than the keel and building. Frequent sudden drum phenomenon is often lost to affect the beauty; the third is that it is generally shared with a lightning protection device with the building subject during installation. Lightning attack; Fourth, the strength of its wind pressure is not high due to the strength of the material itself. At present, high -rise buildings in advanced countries abroad have rarely adopted aluminum -plastic composite boards as curtain walls, and they have switched to single -layer aluminum plates with relatively high security and reliability.

Another opinion is that the aluminum -plastic composite plate is characterized by light weight, proper steel, can be reduced and soundproof, and its decorative effect is better. The second processing is comparable to the aluminum plate, but the cost is much low. Those who support this view believe that after these years of development, the aluminum -plastic composite board has gradually matured technology. Before the material is leaving the factory, it is generally processed by corrosion resistance, weather resistance, collision resistance, folding, pressure resistance, etc. Safety and reliability. The use of aluminum -plastic composite boards on high -rise buildings is used as curtain walls. Although the requirements of wind resistance and pressure are high, the size of the pressure resistance is not only related to the quality and performance of the wall material itself, but also involves the size of the installation size, the length and width ratio of the plate, and the keel configuration of the keel configuration. The degree of denseness and so on.

If strictly follow the requirements of the construction specifications, the aluminum -plastic composite board that is generally composed of quality indicators can be used as a curtain wall for high -rise buildings. In addition, the current techniques and measures for lightning protection are relatively mature. High -rise buildings are generally thoughtful in this regard. As for the aluminum -plastic composite board curtain wall, it is damaged by lightning strikes. There are any precedents outside. Therefore, it can be widely used in the exterior wall decoration of high -rise buildings.

Ayni paytda, "Sohadagi konsensusga ega bo'lish uchun alyuminiy kompozitli pardalar devori", deydi. Ogohlantirishlar oqilona va onalik oqilona ekanligini aytadi. " Biroq, oddiy fuqarolar, alyuminiy yoekstik kompozitsion boshqaruvchilar va yuqori binolar egalari alyuminum alanstik kompozitsion taxta devorlarini berishga umid qilishadi, chunki ular ulardan foydalanish xavfsizligi haqida ko'proq tashvishlanmoqdalar va kompaniya ulardan xavotirda Bozor bozori. Mamlakatimdagi alyuminkastik kompozit taxta ishlab chiqarish 1990-yillarda boshlangan va tez rivojlangan. Bir necha yil ichida alyuminiy yostiqli kompozit taxta, mening mamlakatimda tosh va stakandan keyin mamlakatimda uchinchi eng katta pardali parda materialiga aylandi.

Hozirgi vaqtda mamlakatim dunyoda eng katta foydalanadigan va eksport hajmiga ega mamlakatga aylandi, yillik 200 million kvadrat metr va 20 milliard yuanning mahsuloti ishlab chiqarish qiymati. Biroq, qalbaki va pastligi alyuminiy yassi kompozitlangan taxtani falokatga duchor qiladi. Alyuminiy plastmassa plastinkalari ikki turga bo'linadi: ichki va tashqi devorlar. Ichki osilgan ikki qatlamdan 0,12 mm alyuminiy plitalar va PVXdan iborat. Oqlangan alyuminiy bilan qoplangan kompozit plastinkaning qalinligi 4 mm ga yetishi kerak. PVX moddiy kompozitsiyasi, bo'yoq sirtida flueokarbon bo'yida foydalanish.

Ammo endi bozorda ko'plab mahsulotlar faqat 0,005 mm qalinlikda va hatto yadroli materiallar uchun plastmassada axlat. Xalqaro standartlarga ko'ra, alyuminiy plastmassa plastmassaning o'rtacha narxi kvadrat metr uchun 200 dan 220 yuan, ammo bozordagi eng past narx 1 kvadrat metr uchun 50-60 yuanga sotildi. Kam tarqalgan mahsulotlar quyi mahsulotlar bilan birga, alyuminiy kompozit taxtalarning obro'siga jiddiy ta'sir ko'rsatdi, ular ba'zi mutaxassislarning o'ziga ishonchini yo'qotish va ba'zi odamlar qarshiliklarini kuchaytirishiga olib keladi.

Oraladigan bozordagi hodisalar, ba'zi qalbaki va kesilgan burchaklar doimiy ravishda tashkil etiladi va alyuminiy plastiklarning noto'g'ri qo'llanilishi fenomeni vaqti-vaqti bilan ham sodir bo'ladi. Ba'zilar ichki devor plastinkasini olib tashlash uchun ichki devor plastinkasidan foydalanishadi, ba'zilari oddiy plastinkadan foydalanishadi, ba'zi foydalanuvchilar alyuminum yostiqli kamarli taxtani tushuna olmaydi. Alyuminum chizilgan taxtalarni to'g'ri qo'llang va alyuminiy plastik plastik taxtalarini noto'g'ri tushuntiring. "Alyuminiy plastmassa ipli plastinsa" ning asl milliy standartlari alyuminiy kompozitli taxtalar ishlab chiqishning dastlabki bosqichida shakllantirilgan. Namunaviyda alyuminiy quyma taxtani tushunish tabiiy ravishda ma'lum bir tarixiy cheklovlarga ega.

Masalan, asl "alyuminiy plastmassa kompozitsion kengashi" standartida, alyuminiy yostiqli kompozit plastinka shunchaki ichki devor va tashqi devor taxtasiga bo'lingan. So'nggi bir necha yil ichida ariza va bozorlarni ishlab chiqish orqali alyuminklastik kompozit taxtalarni qo'llash batafsil va aniq bo'ldi. Shuning uchun, me'yorlarga o'z vaqtida tuzatish ishlarni bajarish va qo'llanmani yaxshiroq ko'rsatib, sohaning to'g'ri rivojlanishini va jamiyatning ehtiyojlarini qondirishga yordam beradi.

Dizayner haqida qayg'urayotganda, undan foydalanish xavfsizligini ta'minlash bilan bir qatorda, alyuminiy yostiqli parda devori asosan qurilish shakli va binoning keyingi ikki jihatidan ko'rib chiqiladi. Alyuminiy plitasi katta blok, kuchli plastik, mukammal ishlab chiqarish jarayoni, sirt metal to'qimachiligini idrok etish yanada o'ziga xosdir. Bu juda zamonaviy va juda ko'p rangli navlarga ega. Shuning uchun, bu dizaynerning dizaynidagi fikrlarni aks ettirishi mumkin. biri. Odatda biz odatdagidan keyin tezroq o'zgaradi yoki iflosdan keyin tozalash qiyin.

Bular, shubhasiz, texnik xizmat ko'rsatish va texnik xizmat ko'rsatishning qiyinchiliklarini oshirdi, natijada uch yoki besh yil o'tgach, eng qadimgi narsa. Alyuminiy quyma pardali pardaning devorini osonlashtirishning afzalligi, bu dizaynerlar alyuminum amastalli kompozitsion taxta pardasi devoridan foydalanishga tayyor. Biroq, yuqori yoki ultra-qizlar - qurilishlar alyuminum kengashi pardalari devorlaridan foydalanadi.

Menimcha, bu juda ehtiyotkorlik kerak. Chunki birinchi bo'lib, balandligi zonasi odatda katta va jalb qilingan investitsiyalar juda katta. Ikkinchidan, yuqori darajalarning aksariyati erdan uzoqdir va ularning aksariyati odamlardan uzoqroqqa ko'rinishi mumkin.

Oqibatlar faqat katta ta'sirga qaray oladi va tashqi devor yuzasida hunarmandchilik darajasini ko'rish mumkin emas. Shuning uchun bunday yuqori darajadagi materiallardan foydalangan holda, tashqi devorlarning zarurati shubhali. Uchinchidan, qadimgi davrda o'zlarini bezash bilan o'zlarini bezashning ko'plab namunalari yo'q.

Har bir material o'zining o'ziga xos xususiyatlari va afzalliklariga ega va biz uning afzalliklari va kamchiliklarini materialning bahosidan va narxidan o'zgartirmasligimiz kerak. Alyuminiy yostiqli kompozit taxlamining o'rnatish jarayoni o'z xususiyatlariga ega. Uning qurilish texnologiyasi Hozirda uchta tur mavjud: O'rnatish usulini ochish, qo'shma o'rnatish va o'rnatish usullari. To'g'ri ishlov berish usullari va qurilish jarayonlari o'zlashtirilsa, barcha jihatlarning ishlashi va ko'rsatkichlari milliy standartlarga javob berishi mumkin.

"Alyuminiy plastmassa kompozit plastinsasi" milliy standarti 1999 yilda chiqarildi. Sanoatni tartibga soluvchi va sanoatning sog'lomligini tartibga soluvchi mahsulot sifatini ta'minlashda va sanoatning sog'lomligini ta'minlashda mahsulot sifatini ta'minlashda muhim rol o'ynaydi. Hozirgi kunga qadar ishlab chiqaruvchilar tezda yuzdan ortiq bo'lib, har yili 500 million kvadrat metrdan ortiq mahsulot ishlab chiqarildi.

Mahsulotlar ko'plab tarmoqlarda, masalan, pardalar, yopiq va tashqi bezaklar, reklama, avtomobillar, o'yin-kulgi va biznes kabi keng qo'llaniladi. So'nggi yillarda alyuminkastik kompozit taxta ishlab chiqarish va undan foydalanish tez rivojlandi. Ishlab chiqarish texnologiyasi, uskunalar, menejment va ariza berish darajasi doimiy ravishda ishlab chiqish va takomillashtirish bilan, alyuminiy yostiqli korpus taxtalari tobora muhim sohalarga aylandi. Hayotning barcha yurishlaridan juda katta e'tibor. Ayniqsa, pardali devor materialining yangi turi sifatida, u hayotning barcha turlaridan tobora ko'proq e'tiborga ega bo'ldi.

Endi Xitoy dunyodagi eng yirik alyuminiy plastik ishlab chiqarish markaziga aylandi va alyuminiy kompozit materiallar va alyuminiy kompozit material inspeksiya markazini tashkil qildi.
