6.Uyilo lwesikhongozeli
6.1 Uyilo lulonke lwesikhongozeli
Inkqubo yokugcina ibhetri ihambelana nesitya seenyawo ze-40 esenziwe ngentsimbi echasene nemozulu.Ikhusela kumhlwa, umlilo, amanzi, uthuli, ukothuka, imitha ye-UV, kunye nobusela iminyaka engama-25.Inokukhuselwa ngeebholiti okanye i-welding kwaye ineendawo zokumisa.Ibandakanya iqula lokugcina kwaye ihlangabezana neemfuno zofakelo lwecrane.Isikhongozeli se-IP54 sihlelwe ukuze sikhuseleke.
Iziseko zamandla ziquka zombini izigaba ezimbini kunye nezigaba ezintathu.Intambo yomhlaba kufuneka idibaniswe ngaphambi kokunikezelwa kwamandla kwi-socket yesigaba sesithathu.Isokhethi nganye yokutshintsha kwikhabhinethi ye-AC ine-breaker circuit ezimeleyo yokukhusela.
Ikhabhinethi ye-AC inombane ohlukeneyo wesixhobo sokubeka iliso sonxibelelwano.Njengemithombo yamandla egciniweyo, igcine inqanaba lesithathu lee-breaker zesekethe ezine kunye nezaphuli-mthetho ezintathu zesigaba esinye.Uyilo luqinisekisa umthwalo wamandla olungelelaniso lwesigaba sesithathu.
6.2 Ukusebenza kolwakhiwo lwezindlu
Ulwakhiwo lwentsimbi lwesikhongozeli luya kwakhiwa kusetyenziswa iipleyiti zentsimbi zeCorten A ezinokumelana nemozulu ephezulu.Inkqubo yokukhusela i-corrosion iqukethe i-primer ecebileyo ye-zinc, elandelwa ngumaleko wepeyinti epoxy phakathi, kunye ne-acrylic paint layer ngaphandle.Isakhelo esisezantsi siya kugqunywa ngepeyinti ye-asphalt.
Iqokobhe lesikhongozeli liqulathe iileyibhile ezimbini zeepleyiti zentsimbi, kunye nemathiriyeli yokuzalisa iBanga A loboya obungangeni emlilweni phakathi.Le nto yokuzalisa uboya belitye ayinikezeli kuphela ukuchasana nomlilo kodwa ineempawu zokungena manzi.Ubunzima bokuzalisa isilingi kunye neendonga zecala kufuneka bungabi ngaphantsi kwe-50mm, ngelixa ubuninzi bokuzaliswa komhlaba kufuneka bungabi ngaphantsi kwe-100mm.
Ingaphakathi lesikhongozeli liza kupeyintwa nge-primer ecebileyo ye-zinc (enobunzima be-25μm) ilandelwa ngumaleko wepeyinti ye-epoxy resin (enobunzima obungama-50μm), okukhokelela kubunzima befilimu yepeyinti engekho ngaphantsi kwe-75μm.Kwelinye icala, umphandle uya kuba neprimer etyebileyo zinc (enobunzima obuyi-30μm) ilandelwa ngumaleko wepeyinti epoxy resin (enobunzima obungama-40μm) kwaye igqityezelwe ngerabha yerabha ekrwadayo ye-acrylic ephezulu yepeyinti (enobunzima. ye-40μm), okukhokelela kubunzima befilimu yepeyinti epheleleyo engekho ngaphantsi kwe-110μm.
6.3 Umbala wesikhongozeli kunye ne-LOGO
Iseti epheleleyo yezikhongozeli zezixhobo ezibonelelwe yinkampani yethu zitshizwa ngokwelona nani liphezulu leziqhamo eliqinisekiswe ngumthengi.Umbala kunye ne-LOGO yezixhobo zekhonteyina zilungiselelwe ngokweemfuno zomthengi.
