Alyuminiy qotishma eshik va derazalarni qanday tanlash mumkin
Po'lat yog'och eshik va derazalar bilan taqqoslaganda, alyuminiy qotishma eshik va derazalar quyidagi afzalliklarga ega:
1) Engil vazn va yuqori quvvat. Zichlik po'latning faqat 1/3 qismini tashkil qiladi.
2) Yaxshi muhrlanish ko'rsatkichi. Havo o'tkazmaydigan ishlash to'g'ridan-to'g'ri eshik va derazalar funktsiyasi va energiya sarfiga ta'sir qiladi. Sızdırmazlık ko'rsatkichi to'rt jihatni o'z ichiga oladi: havo o'tkazmasligi, suv o'tkazmasligi, issiqlik izolyatsiyasi va ovoz yalıtımı.
3) Yaxshi chidamlilik, ishlatish va saqlash oson. Alyuminiy qotishma eshik va derazalar zanglamaydi, pasaymaydi va yiqilmaydi, deyarli hech qanday texnik xizmat ko'rsatish talab qilinmaydi va ehtiyot qismlarning xizmat qilish muddati juda uzoq.
4) Dekorativ effekt oqlangan. Alyuminiy qotishma eshik va derazalar yuzasi sun'iy oksidli plyonkaga ega va kompozit plyonka qatlamini hosil qilish uchun rangli bo'ladi. Ushbu kompozit plyonka nafaqat korroziyaga{1}}bardoshli va eskirishga-bardoshli, balki ma'lum bir yong'inga chidamliligi va yuqori yorqinligiga ham ega. Alyuminiy qotishma eshiklari va derazalarining engil og'irligi tufayli ishlov berish va yig'ish aniq va to'g'ri, shuning uchun ochilish va yopish engil va moslashuvchan bo'lib, shovqin yo'q.
Alyuminiy qotishma materiallari uchun eshik va derazalarning deformatsiyalanishi, itarilishi va tortilishi va hokazo bo'lishi odatiy hol emas. Iste'molchilar sotib olayotganda quyidagi fikrlarga e'tibor berishlari kerak:
Materialni ko'rib chiqing. Materiallarga murojaat qilish uchun 6 ta asosiy jihat mavjud:
⒈Thickness: There are two types of aluminum alloy sliding doors: 70 series and 90 series, and 70 series can be used for aluminum alloy sliding doors inside the house. The series number indicates the thickness of the door frame in millimeters of the construction dimension. There are four kinds of aluminum alloy sliding windows: 55 series, 60 series, 70 series and 90 series. The selection of the series should be determined according to the size of the window opening and the local wind pressure value. Aluminum alloy sliding windows used as closed balconies should not be less than 70 series.
⒉ Strength: The tensile strength should reach 157 Newtons per square millimeter, and the yield strength should reach 108 Newtons per square millimeter. When purchasing, you can bend the profile moderately with your hands, and it should be able to return to its original shape after letting go.
3. Xromatiklik: Xuddi shu alyuminiy qotishma profili bir xil rang va yorqinlikka ega bo'lishi kerak. Rang farqi aniq bo'lsa, u sotib olish uchun mos emas.
⒋ Flatness: Check the surface of the aluminum alloy profile, there should be no dents or bulges.
⒌Gloss: Aluminum alloy doors and windows should avoid buying profiles with open bubbles (white spots) and slag (black spots) on the surface, as well as cracks, burrs, peeling and other obvious defects.
⒍Oxidation degree: The thickness of the oxide film should reach 10 microns. When purchasing, you can swipe on the surface of the profile to see if the oxide film on the surface can be wiped off.
