The crack resistance of spray-coated cable tray in vibration environment is affected by multiple factors. From the perspective of substrate selection, galvanized steel sheet substrate exhibits better vibration resistance than cold-rolled steel substrate due to the stress buffering effect of zinc layer. In terms of powder type, epoxy resin coating has high hardness but high brittleness, and is prone to microcracks in long-term vibration environment; in contrast, polyester resin is more adaptable to vibration environment with better toughness (elongation is usually >5%). The coating thickness also needs to be strictly controlled. Too thick (>120 mm. Moslashuvchanlikni kamaytiradi. Uni 60-100 metr masofalarida saqlash tavsiya etiladi.
Amalga oshirilgan amaliy ishlash shuni ko'rsatadiki, yotqizilgan püskürtme - malakali püskürtme (5N · motfera ta'siri), ammo {}}} asarlar uchun ta'sirlanish yoki bo'shashish vositasi, bu hali ham chekka rezonanslash yoki bo'g'im yoki bo'g'imdan bo'g'inga olib kelishi mumkin. Seminarning dolzarb ishi shuni ko'rsatadiki, polier promasi - dan keyin kamar ulanishida mahalliy qoplamali po'stlog'i bor va u keyinchalik tarqalmadi.
Yoriqga chidamliligini oshirish maqsadida bir qator yaxshilanish choralarini ko'rish tavsiya etiladi. Moddiy tanlovlar bo'yicha, o'zgartirilgan poliester kukuni (masalan, elastometr qo'shayotgan kabi) ustuvor ahamiyat berilishi kerak; Tarkibiy ulanishlar nuqtai nazaridan, kauchuk Gaktets-dan foydalanish kerak, rezina toshkasblari tebranish uchun ishlatilishi kerak va qo'llab-quvvatlash punktlarining zichligi mos ravishda ko'payishi kerak (kosmik 1,5 m); Jarayonni boshqarish nuqtai nazaridan, - preparat fosh bo'lishiga puxta va davolash parametrlari bu standartlarga javob berishini ta'minlash kerak. Kundalik parvarishlashda kontakt maydonchalari, patnislar va qo'llab-quvvatlash tuzilmalarini tekshirishga e'tibor qaratish lozim. Agar yoriqlar topilsa, ular vaqt o'tishi bilan sayqallanishi va tozalanishi kerak va keyin püskürtülür.
Umuman olganda, püskürtülamning umumiy tebranish sharoitida katta turg'unlik qiladi, ammo 2,6}} asarida yuqori - asarlar uchun, poliestr püskürtülülme echimini olish va ekstremal tebranish muhiti, metall yalang'och ramkadan foydalanishning muqobil echimini tanlash tavsiya etiladi - sayt anti {}} korroziya hisoblanishi mumkin. Tizimli material tanlash, strukturaviy optimallashtirish va standartlashtirish va standartlashtirilgan o'rnatish orqali, uzoq vaqt {{}}} Aprey {{}} {}} {}} qoplangan kabel patchisining tebranish muhitida samarali kabelli kabelning evaziga samarali ishlashi mumkin.
