Kodi mungazindikire bwanji zinthu zogwiritsidwa ntchito popanga zinthu? Kuchokera ku makhalidwe oyaka ndi kuchuluka kwa kuvala kwa mbali ziwiri za tsatanetsatane

Pogula ma caster, tiyenera kusamala kwambiri ndi zinthu zomwe ma caster amapanga, chifukwa zinthu zomwe ma caster amapanga zimagwirizana mwachindunji ndi chitonthozo, kulimba komanso chitetezo cha kugwiritsa ntchito. Munkhaniyi, tikuwonetsani momwe mungadziwire zinthu zomwe ma caster amapanga kuchokera ku mbali ziwiri za mawonekedwe a caster burn ndi kuchuluka kwa kukana kuvala.

Makhalidwe Oyaka
Ma casters opangidwa ndi zinthu zosiyanasiyana amakhala ndi makhalidwe osiyanasiyana akatenthedwa, zomwe ndi zofunika kwambiri zomwe tingagwiritse ntchito pozindikira zinthuzo.
Nayiloni (PA): siiyaka mosavuta, imayaka lawi lachikasu, imakhala ndi fungo la misomali, imayaka ubweya, ndipo imatulutsa utsi woyera, imayaka pamwamba, imatuluka matuza, komanso imasungunuka ndi madontho.
Polyurethane (PU): yosavuta kuyaka, yoyaka ndi utsi woyera wochepa, yosavuta kusungunuka, yopanda fungo losasangalatsa, silika womata.
Polyvinyl chloride (PVC): yosavuta kuyaka, kuyaka ndi utsi wakuda wakuda, fungo losasangalatsa, kuyaka popanda silika womata, pamwamba pake mukatha kuyaka ufa wakuda wa kaboni.
Polypropylene (PP): yosavuta kuyaka, pali fungo lochepa la pulasitiki, pamwamba pake pali kusungunuka kofanana, ndipo pamwamba pake pali silika womata. Nayiloni (PA): si wovuta kuyaka, imayaka ndi fungo la tsitsi lotentha, pamwamba pake pamakhala matuza, ndipo pamwamba pake pali silika womata.

Kukana kwa kukwiya
Kukana kwa ma casters ndi chinthu chofunikira chomwe chimakhudza moyo wa ntchito, ndipo kuchuluka kwa kukana kwa ma casters opangidwa ndi zipangizo zosiyanasiyana nakonso n'kosiyana. Makamaka:
Gudumu la nayiloni: Kukana kuvala gudumu la nayiloni ndikobwino, koyenera kugwiritsidwa ntchito pamalo osalala a msewu, koma poyerekeza ndi gudumu la rabara ndi lotsika pang'ono.
Gudumu la rabara: gudumu la rabara lili ndi kukana kwabwino kwa kukwawa, limatha kusintha kuti ligwirizane ndi malo osiyanasiyana amisewu, komanso limakhala ndi nthawi yayitali yogwirira ntchito.
Gudumu la PVC: Gudumu la PVC silili ndi mphamvu yolimba yolimbana ndi kukwawa, ndi losavuta kuvala ndi kukanda, komanso nthawi yogwira ntchito ndi yochepa.
Gudumu lofewa la rabara: gudumu lofewa la rabara limakhala ndi kukana kwabwino kwa kukwawa, koma ndi lotsika pang'ono poyerekeza ndi gudumu la rabara.
Chifukwa chake, tikhoza kuweruza zinthuzo poona kutha ndi kung'ambika kwa zinthuzo pakugwiritsa ntchito ndikumvetsetsa ma coefficients a kukana kwa zinthu zosiyanasiyana.

Tiyenera kudziwa kuti zomwe zili pamwambapa ndi zinthu ziwiri zokha zomwe zimagwiritsidwa ntchito popanga zinthu zoyambira. Ndipotu, palinso zinthu zina zomwe zimagwiritsidwa ntchito popanga zinthu zoyambira, monga kulemera ndi mphamvu, zomwe zimakhudzanso magwiridwe antchito a zinthu zoyambira. Chifukwa chake, pogula zida, tiyenera kuganizira zinthu zingapo mokwanira ndikusankha zinthu zoyenera kwambiri kwa ife eni.
