Umbala weimibhobho yesinyithi esenziwe ngentsimbiidla ngokunxulunyaniswa nokusetyenziswa kwazo, unyango lokulwa nokugqwala okanye imigangatho yoshishino. Amazwe ahlukeneyo kunye namashishini anokuba neemfuno ezithile zemibala ukuqinisekisa ukhuseleko, ukumelana nokugqwala okanye ukuchongwa okulula. Oku kulandelayo luhlelo oluneenkcukacha:
1. Intsingiselo ngokubanzi yombala wepayipi ye-DINSEN SML
·Umnyama/ungwevu omnyama/Isinyithi okanye i-asphalt yokuqala/uphahla oluchasene nokugqwala Ukukhupha amanzi, indle, imibhobho kamasipala
·Bomvu/Imibhobho yomlilo, ukumelana nobushushu obuphezulu okanye iimpawu ezikhethekileyo/Inkqubo yomlilo, unikezelo lwamanzi olunoxinzelelo oluphezulu
·Luhlaza/Imibhobho yamanzi okusela, izinto zokugquma ezinobuhlobo nokusingqongileyo (ezifana ne-epoxy resin)/Amanzi empompini, unikezelo lwamanzi olukumgangatho wokutya
·Luhlaza/Amanzi emizi-mveliso, umoya ocinezelweyo/Umzi-mveliso, inkqubo yomoya ocinezelweyo
·Lubhelu/Imibhobho yegesi (isinyithi esincinci, uninzi lwemibhobho yentsimbi)/Ukuhanjiswa kwegesi (ezinye iindawo zisasebenzisa isinyithi esityhidiweyo)
·Isilivere/Unyango oluchasene nomhlwa olugayiweyo/Indawo engaphandle, enomswakama, iimfuno eziphezulu zokumelana nokugqwala
2. Iimfuno ezikhethekileyo zemibala yepayipi yesinyithi esityhidiweyo kwiimarike zasekhaya nezangaphandle
(1) Imakethi yaseTshayina (umgangatho we-GB)
Imibhobho yesinyithi esityhidiweyo: idla ngokuba mnyama (i-asphalt anti-corrosion) okanye i-original iron grey, egqunywe kancinci nge-epoxy resin (eluhlaza).
Umbhobho wesinyithi obonelelwa ngamanzi:Umbhobho wesinyithi oqhelekileyo: omnyama okanye obomvu (wokukhusela umlilo).
Umbhobho wentsimbi othuliweyo (DN80-DN2600): udonga lwangaphandle olutshizwe nge-zinc + asphalt (mnyama), udonga lwangaphakathi lutshizwe ngesamente okanye i-epoxy resin (grey/green).
Umbhobho woKhuseleko loMlilo: upende obomvu, ohambelana nenkcazo yokhuseleko lomlilo ye-GB 50261-2017.
Umbhobho wegesi: umthubi (kodwa imibhobho yegesi yanamhlanje yenziwe kakhulu ngemibhobho ye-PE okanye yentsimbi, kwaye isinyithi esityhidiweyo asisetyenziswa rhoqo).
(2) Imakethi yase-US (uMgangatho we-AWWA/ANSI)
I-AWWA C151 (umbhobho wesinyithi othambileyo):
Udonga olungaphandle: ludla ngokuba mnyama (ukwaleka nge-asphalt) okanye isilivere (efakwe i-galvanized).
Ingaphakathi: i-samente mortar (grey) okanye i-epoxy resin (eluhlaza/ebhlowu).
Umbhobho Wokukhusela Umlilo (umgangatho we-NFPA): uphawu olubomvu, ezinye zifuna amagama athi “INKONZO YOMLILO” ukuba aprintwe.
Umbhobho Wamanzi Okusela (isiqinisekiso se-NSF/ANSI 61): ulwelo lwangaphakathi kufuneka luhlangabezane nemigangatho yococeko, akukho mfuneko inyanzelekileyo yombala wodonga lwangaphandle, kodwa ilogo eluhlaza okanye eluhlaza okwesibhakabhaka isetyenziswa rhoqo.
(3) Imarike yaseYurophu (EN umgangatho)
EN 545/EN 598 (umbhobho wentsimbi ophumayo):
I-Anticorrosion yangaphandle: i-zinc + i-asphalt (emnyama) okanye i-polyurethane (eluhlaza).
I-Inner Lining: i-samente mortar okanye i-epoxy resin, akukho mithetho ingqongqo yombala, kodwa kufuneka ihambelane nemigangatho yamanzi okusela (njengesiqinisekiso se-KTW).
Umbhobho woMlilo: obomvu (amanye amazwe afuna ukuprintwa "FEUER" okanye "FIRE").
Umbhobho wezoShishino: usenokuba luhlaza okwesibhakabhaka (umoya ocinezelweyo) okanye otyheli (igesi, kodwa imibhobho yesinyithi esityhidiweyo iye yatshintshwa kancinci kancinci).
(4) Imarike yaseJapan (i-JIS eqhelekileyo)
I-JIS G5526 (umbhobho wentsimbi othambileyo): Udonga lwangaphandle ludla ngokuba mnyama (i-asphalt) okanye i-galvanized (isilivere), kwaye ulwelo lwangaphakathi luyisamente okanye i-resin.
Umbhobho womlilo: upende obomvu, eminye ifuna ukuprintwa "kokulwa nomlilo".
Umbhobho wamanzi okusela: ilayini eluhlaza okanye eluhlaza okwesibhakabhaka, ehambelana nomgangatho we-JHPA.
3. Impembelelo yombala weengubo ezikhethekileyo zokulwa nokugqwala
I-epoxy resin coating: idla ngokuba luhlaza okanye luhlaza okwesibhakabhaka, isetyenziselwa iimfuno eziphezulu zokulwa nokugqwala (ezifana namanzi olwandle, ishishini leekhemikhali).
Ingubo yePolyurethane: isenokuba luhlaza, mnyama okanye mthubi, inokumelana kakhulu nemozulu.
Ingubo ye-Zinc + asphalt: udonga olumnyama lwangaphandle, olufanele iipayipi ezingcwatyiweyo.
4. Isishwankathelo: Ungayikhetha njani umbala wemibhobho yesinyithi esityhidiweyo?
Khetha ngokusebenzisa:
Ukukhupha amanzi amdaka/indle → mnyama/ngwevu
Amanzi okusela → luhlaza/luhlaza okwesibhakabhaka
Ukucinywa komlilo → obomvu
Ishishini → ngokuchongwa okuphakathi (njengegesi etyheli, umoya ocinezelweyo oluhlaza okwesibhakabhaka)
Khetha ngokwemigangatho:
ITshayina (GB) → mnyama (indlela yokukhupha amanzi), obomvu (ukucima umlilo), oluhlaza (amanzi okusela)
IYurophu neMelika (AWWA/EN) → mnyama (ongamelani nokugqwala kwangaphandle), oluhlaza/oluhlaza okwesibhakabhaka (i-lining)
IJapan (JIS) → umnyama (udonga lwangaphandle), ubomvu (ukucima umlilo)
