ʻO ke kaulahao ʻoihana piha
He ʻoihana koʻikoʻi ka mining underground, ʻo ia ke kumu he mea nui ka ducting i ka ʻoihana mining. I ka ʻeli ʻana ma lalo o ka lepo, hele mai ke kaiapuni me nā mea haumia he nui paha e pōʻino ai nā miners, e komo pū me nā kinoea ʻona a me nā uahi. No ka pale ʻana i ka ʻai ʻana i kēia mau mea ʻino.
He mea ko'iko'i loa 'o JULI ducting spiral flexible no ka ea. Ma muli o kona hiki ke kulou a kikoo, hana maikaʻi ʻo ia i nā kumu mining ma lalo o ka lepo i pololei ʻole. Hāʻawi ia i ka ventila maikaʻi i nā kūlana paʻakikī loa.
ʻOi aku ka mea nui o ka mea i hoʻohana ʻia no ka hana ʻana i ka duct ventilation. Loaʻa i nā mines ka nui o nā kaiapuni like ʻole, nā mea a me nā mahana. Hiki ke hoʻopilikino ʻia ka ducting flexible JULI no kēlā me kēia mines, me ke ahi retardant, antistatic, wela, anawaena etc. JULI ventilation duct hoʻohana i ka lole laminated PVC a me ka lole semi-coated i ka hana like ʻole o ka lawelawe ʻana i ke ola e hoʻopili i nā manawa hana ʻokoʻa i loko o nā mines. Hoʻopili maikaʻi ʻia ka laina hana ducting maʻalahi e hoʻomaikaʻi i ka pono o ka ea a hōʻemi i ka leakage.
Ke nānā aku nei ʻo Chengdu Foresight Composite Co., Ltd. i ka ea ma lalo o ka honua no nā makahiki he 15, ʻo ia ke kumu e haʻaheo ai mākou e hāʻawi i nā koho ducting flexible kiʻekiʻe loa.
Ma lalo iho nei, e ʻoluʻolu e nānā i nā ʻauwaʻa ea ma lalo o ka honua:
