Warqad midab leh oo dahaaran iibinta kulul ayaa loo dhoofiyay Koonfurta Ameerika

Xaashiyaha dahaarka leh ee midabka leh waa badeeco ka samaysan xaashi bir ah oo qabow-duuban iyo xaashi bir galvanized ah oo ah walxo salka, ka dib daawayn dusha sare ah (hoos u dhigista, nadiifinta, daaweynta beddelka kiimikada), dahaarka joogtada ah (hab duuban), dubista, iyo qaboojinta. Habka ugu muhiimsan ee wax soo saarka ee caadiga ah ee labajibbaaran iyo laba-dubida unugga midabka joogtada ah ee joogtada ah waa uncoiling, pre-dahaarka, dubista, iyo duubista.

Astaamaha xaashida midabka leh:

Ku habboon jarista, foorarsiga, samaynta duubista, shaambaynta, boodhka, bakteeriyada, filimka, saxanka birta ah ee birta ah waa alaabta dusha sare ee qurxinta casriga ah sababtoo ah daaweynta caarada-ka-hortagga. Saxanka midabka leh ayaa u adkaysta aashitada iyo alkali, birta hoosena waxay leedahay caabbinta daxalka oo wanaagsan iyo caabbinta aashitada iyo alkali, sidaas darteed saxanka midabkiisu wuxuu leeyahay iska caabin kiimiko oo heer sare ah.

Gudida isku dhafan ee heerkulka sare ee PVC ee dabka u adkaysta waxay isticmaashaa walxo filim ah oo PVC ah oo dabka u adkaysta, taas oo ah walxo ololaya, heerka dab-demiska wuxuu gaaraa B1. Waxqabadka is-daminta, waxay ka hortagi kartaa gubasho waqti dheer ah; adkeysiga, adhesion aad u fiican oo u dhexeeya filimka iyo birta birta ah ayaa u adkaystay imtixaanka wakhtiga, filimka dusha sare waa sahlan tahay in la ilaaliyo oo aad u dhaqaale.

Cadaadiska cimilada ee guddiga midabka midabka leh ayaa lagu dari karaa caanaha ka hortagga ultraviolet, taas oo aan isbeddelin midabka ka dib sanado badan oo la isticmaalo. Dabaqyada midabka leh ayaa deegaan ahaan u wanaagsan. Alaabooyinka ka samaysan birta dahaarka leh ee PVC way fududahay in la nadiifiyo, u adkaysta xoqidda, waxay yareeyaan kharashka dayactirka iyo kharashka shaqada, waana alaab deegaan iyo saaxiibtinimo u leh.

Codsiga xaashida Midabka leh:

Marka lagu daro ilaalinta zinc, dahaarka organic ee lakabka zinc wuxuu door ka ciyaaraa daboolida iyo go'doominta, taas oo ka hortagi karta saxanka birta ee miridhku waxayna leedahay nolol adeeg oo ka dheer birta galvanized. Tusaale ahaan, meelaha warshadaha ama xeebaha, sababtoo ah saamaynta sulfur dioxide gaaska ama cusbada hawada, heerka daxalka waa la dedejiyey oo nolosha adeegga ayaa saameeya. Xilliga roobka, oo daahan lagu qooyay roobka muddo dheer, ama meesha farqiga heerkulka u dhexeeya habeen iyo maalin uu aad u weyn yahay, waxay si dhakhso ah u daxalaysaa oo gaabin doontaa nolosha adeegga. Dhismayaasha ama baabuurta ka samaysan birta midabka midabka leh waxay inta badan helaan nolol dheer marka roobku maydho, haddii kale waxay saamaynaysaa saamaynta gaasta sulfur dioxide, cusbada iyo boodhka. Sidaa darteed, naqshadeynta, haddii jiirada saqafka ay weyn tahay, uma badna inay ku ururto boodhka iyo wasakh kale, iyo nolosha adeeggu waa dheer tahay; Meelahaas ama qaybaha aan inta badan roobku maydhin, waa in si joogto ah loogu dhaqo biyo.

Shirkadeena waxay ku takhasustay soo saarista taarikada midabka midabka leh, oo leh tiro badan oo ah taarikada midabka midabka leh ee kaydka, hubinta tayada, iyo bixinta degdega ah! Midabo kala duwan ayaa la heli karaa, taageero si loo habeeyo cabbirro kala duwan, bixinta agab kala duwan, nala soo xiriir si aad u hesho qiimaha ugu wanaagsan ee warshadda!
