1. Hom nqa lub teeb ncej thiab lawv qhov zoo thiab qhov tsis zoo
Yog tias lub teeb nqa nqa tau muab faib raws li cov khoom siv, nws tuaj yeem muab faib ua hlau nqa lub teeb ncej, FRP nqa lub teeb ncej, cement nqa lub teeb ncej thiab aluminium alloy nqa lub teeb ncej.
(1) Qhov zoo thiab qhov tsis zoo ntawm cov hlau nqa lub teeb ncej
Qhov zoo: siab zog.
Disadvantages: yooj yim rau corrode los yog xeb, siab tsheb thauj mus los thiab installation cov nqi, installation txoj kev thiab kev kho deg muaj tej yam kev txwv.
(2) Qhov zoo thiab qhov tsis zoo ntawm FRP nqa lub teeb ncej
Qhov zoo: lub teeb yuag, yooj yim installation, thiab tuaj yeem ntsia tau rau hauv txoj kev plug-in.
Disadvantages: Lub neej ua haujlwm luv luv, tsis tuaj yeem rov ua dua, tus nqi saib xyuas siab, thiab muaj kev cuam tshuam rau kev puas tsuaj.
(3) Qhov zoo thiab qhov tsis zoo ntawm cov cement nqa lub teeb ncej
Qhov zoo: Plug-in installation yog ua tau, nrog lub zog zoo thiab tsis tas yuav txau.
Qhov tsis zoo: hnyav hnyav, nyuaj thiab kim rau nruab, tsis tuaj yeem rov siv dua, thiab muaj qee yam txaus ntshai.
(4) Qhov zoo thiab qhov tsis zoo ntawm aluminium alloy nqa lub teeb ncej
Qhov zoo: Nws muaj kev tiv thaiv corrosion zoo heev thiab tsis muaj txij nkawm. Lub teeb yuag ua rau nws yooj yim rau nruab thiab thauj. Nws tuaj yeem rov ua dua tshiab hauv ntau qhov kev ua tiav thiab tseem tuaj yeem ntsia tau rau hauv txoj kev ntsaws.
Disadvantages: Lub zog yog me ntsis phem dua li ntawm tus ncej hlau.
2. Cov txheej txheem ntawm kev nqa lub teeb ncej
Cov txheej txheem ntawm kev nqa lub teeb ncej yog raws li hauv qab no: blanking → dabtsi yog khoov → vuam → kho thiab sib tsoo → shaping → → head-to-head installation ntawm lub phaj hauv qab → vuam puag phaj → qhov rooj qhib → vuam qhov rooj strips, hluav taws xob strips, xauv hauv qab → nkhaus nkhaus → galvanized → txau → kev tshuaj xyuas dav dav.
