HLCALMINIYA -Alyuminiy kompozit panel ishlab chiqaruvchilari

Alyuminiy plastik plastinkalarini tozalash sabablarini tahlil qilish:

Alyuminiy plastmassa plitasi - bu yadroda, polietilen va polipropilen plastmassa bilan davolash va qoplangan alyuminiy plitalardan yasalgan yangi materiallar. Alyuminiy yostrastik taxtalari tabiatda mutlaqo boshqacha (metall va pulsiz) dan iborat bo'lganligi sababli, bu nafaqat asl tarkibiy materiallarning asosiy xususiyatlarini (metall alyuminen, bo'lmagan polietilen plastikning asosiy xususiyatlarini saqlab qoladi Dastlabki tarkibiy materiallarning kamchiliklari, keyinchalik hashamatli, ob-havo qarshiligi, yo'lovchilarga chidamliligi, yong'inga chidamliligi, yong'inga qarshi, namlik, namlik, izolyatsiya, seysmik qarshiligi kabi ko'plab a'lo materiallarni olish; O'rnatish va boshqa xususiyatlar, bu xususiyatlar alyuminum peshtaxta uchun keng istiqbollarni ochib berdi. Alyuminiy alanstik kompozit plitalarini ishlab chiqarish Laymmen uchun juda sodda, ammo aslida bu yuqori texnik tarkibga ega yangi mahsulot. Shu sababli, alyuminiy durustik taxtaning sifatini nazorat qilish ma'lum texnik qiyinchiliklarga ega.

Quyidagi asosan alyuminiy kompozit panelining tozalash kuchiga ta'sir etuvchi omillar haqida gapiradi.

1. Alyuminiy folga sifatining o'zi:

Garchi bu yashirin muammo bo'lsa-da, u allaqachon alyumin -plastik taxtalar sifatida aks ettirilgan. Bir tomondan, alyuminiy materiallarning issiqlik bilan davolash jarayoni, boshqa bir qator alyumin plitalar va ishlab chiqaruvchilar qayta ishlangan chiqindilarni ishlatganda sifat nazorati bilan qat'iy emas.

Buning uchun alyuminiy plastik panellarini ishlab chiqaruvchilardan malakali pudratchisidan keyin material sifatini ta'minlash uchun turli sohalarda baholashni aniqlash uchun alyuminiy plastmassalar ishlab chiqaruvchilarini talab qiladi.

2. Alyuminiy plitalarni oldindan davolash:

Alyuminiy plitalarining kompozitsion sifatiga bevosita bog'liq alyuminiy plitaning tozalash va qatlamining massasi. Alyuminiy plitasi avval tozalangan ifloslanishning ifloslanishini, shunda sirt zich kimyoviy qatlamni hosil qiladi, shunda yuqori molekulyar membrana yaxshi bog'lanishini hosil qilishi uchun.

Biroq, ba'zi ishlab chiqaruvchilar qayta ishlash jarayoniga ta'sir qiladigan ishlov berish jarayonini qayta ishlash paytida harorat, kontsentratsiya, qayta ishlash vaqtini va qayta ishlash jarayonini qayta ishlashning haroratini nazorat qilmaydilar.

Bundan tashqari, ba'zi yangi ishlab chiqaruvchilar to'g'ridan-to'g'ri alyuminiy plitalar bilan oldindan davolanmasdan qo'llaniladi. Bularning barchasi 180 ° katodali yoki past yoki beqaror tozalangan kuchga olib keladi.

3. Asosiy materiallarni tanlash:

Chunki polimer membranasi va pe boshqa plastmassalar bilan taqqoslaganda eng yaxshi ta'sir va mo''tadil narx, noxotir va oson ishlov berish oson. Shunday qilib, asosiy materiallar pe-dan foydalanadi. Xarajatning narxini pasaytirish uchun ba'zi kichik ishlab chiqaruvchilar PVX-ni kambag'al bog'lash effektlari va yonish materiallari bilan yoki pastki burchakli materiallar bilan pe xom ashyosi bilan aralashtiriladi.

Shu tarzda, bir kompozit harorat pe, qarish va boshqalarning turli xil modellari tufayli boshqacha bo'ladi va yakuniy sirt kompozitura beqaror.

4. Polimer membranalarni tanlash:

Polimer membranasi maxsus ishlashi bilan yopishqoq materialdir, bu esa murakkab sifatning asosiy omiliga ta'sir qiladi. Yuqori molekulyar membrana ikki tomonga ega va uchta qatlam birgalikda siqiladi.

Bir tomonda metall bilan bog'lanish kerak, boshqa tomoni pe bilan bog'langan, o'rta qatlam esa pe substrat va ikki tomonning tabiati butunlay boshqacha. Ikkala tomondagi materiallarning narxi har xil. Alyuminiy do'konlari bilan bog'langan materiallar olib kirish kerak va narx qimmat.

She bilan joylashtirilgan materiallar Xitoyda ishlab chiqarilishi mumkin. Shuning uchun, ba'zi baland exulyar membrana ishlab chiqaruvchilar katta maqolalarni yaratadilar va katta foyda keltiradigan materiallarni kamaytirish uchun pe fayllarini ishlatishadi. The use of high molecular membranes is directed, and the front and back cannot be changed. Yuqori molekulyar membrana - bu psevdo -Cary-ning shaxsiy plyonkasi.

Early intensity and long time, due to weathering impact, reduce intensity, even bubble or open glue.

Analysis of the common quality problems in the aluminum -plastic panel curtain wall project:

1. The discoloration and discoloration of aluminum plastic panels:

The aluminum -plastic plate produces discoloration and discoloration, mainly caused by improper selection of boards. The aluminum plastic board is divided into indoor plates and outdoor plates. The surface coating of the two plates is different, which determines different occasions.

The surface used in the room usually spray resin coating on the surface. This coating cannot adapt to the harsh natural environment of the outdoor. If it is used outdoors, it will naturally accelerate its aging process and cause discoloration. The surface coating of outdoor aluminum plastic panels is generally used for anti -aging and strong anti -ultraviolet capacity. The price of this plate is expensive. Some construction units deceived the owners and impersonated high -quality fluorocarbon plates that were anti -aging and corrosion in the interior, squeezing unreasonable profits, which caused serious discoloration and discoloration of aluminum plates used in the project.

2. The gel and shedding of aluminum -plastic plates:

The aluminum plastic panel is opened and shedded, mainly due to improper adhesives. As an ideal adhesive for outdoor aluminum plastic board projects, silicone gel has unique and superior conditions. In the past, my country's silicone gums mainly rely on imports, and their worth of many people was discouraged. Only those high -rise buildings on high -rise buildings dared to ask for help.

Now, Zhengzhou, Guangdong, Hangzhou and other places in my country have put into production of silicone gums of different brands, causing prices to plummet. Now, when buying aluminum plastic panels, the sales provider will recommend the dedicated fast -drying glue. This kind of glue is still available indoors. For outdoor outdoor of climate change, the phenomenon of opening and dehydration of plates appears.

3. Deformation and drums on the surface of the aluminum plastic board:

There are many reasons for the surface deformation and drumming of aluminum -plastic plates. In the previous construction, this quality problem had occurred, and we once thought that the quality of the board itself; later, after everyone's centralized analysis, the main problem lies in the grass -roots plates of aluminum -plastic boards, followed by aluminum -plastic plastic. The quality of the board itself. Dealers often provide us with the construction process of aluminum -plastic boards. The recommended grass -roots materials they recommend are mainly high -density boards, woodworking boards and the like.

In fact, when used outdoors, this material is very fragile. After wind blowing, sun exposure, and rain, it will inevitably produce deformation. Now that the grass -roots materials are deformed, is the aluminum -plastic plate as the surface layer that does not deform? It can be seen that the ideal outdoor grassroots material should be tied to skeleton by rust -proofing steel and square steel pipes. If conditions permit, aluminum profiles are more ideal.

The skeleton made of such metal materials is not much higher than the wooden keel and high -density plate, which can indeed ensure the quality of the project.

4. Aluminum -plastic plate gel sewing is neat:

When the aluminum plastic board is decorated on the surface of the building, there are generally a certain width gap between the plates. For aesthetic needs, black sealing glue must be filled in the gap.

In order to save time, some construction personnel do not use paper gum to ensure that the glue is neat and regular, but instead use the protective film on the surface of the aluminum -plastic plate as a substitute. Because the aluminum -plastic plate is cut, the protective film will cause to tear to varying degrees, so it is not possible to use it to protect the tape alternative.
