1.塑钢门窗的特点以 PVC 为主要原料,加入稳定剂、改性剂、填充剂、紫外线吸收剂等,经加工制成各种断面为中空的型材,以其为材料组装成的门窗称为塑钢门窗。塑钢门窗具有强度高、耐冲击的特点。它的耐候性好,适用范围可达-40℃—70℃,不脆化、不变色,使用年限可达50年以上;它的隔热性好,热传导率低,节约能源。同时,塑钢门窗还具有优良的耐腐蚀性、气
1. The characteristics of steel doors and windows With PVC as the main raw material, adding stabilizers, modifiers, fillers, UV absorbers, processed into a variety of cross-section of the hollow profiles, with its assembled into windows and doors as Steel doors and windows. Plastic doors and windows with high strength, impact-resistant features. Its weather resistance is good, the scope of application up to -40 ℃ -70 ℃, not embrittlement, no discoloration, the useful life of up to 50 years or more; its good insulation, low thermal conductivity, energy conservation. At the same time, steel doors and windows also have excellent corrosion resistance, gas
