Tuubo galvanized ah oo kulul lagu dhex geliyo

Birta dhalaalaysa waxay la falgashaa matrix-ka birta si ay u soo saarto lakab bir ah, si matrix-ka iyo dahaarka la isugu daro. Galvanization-ka kulul ee lagu shubo waa in marka hore la shiido tuubada birta ah, si looga saaro oksaydhka birta dusha sare ee tuubada birta ah, ka dib marka la shiido, iyada oo loo marayo ammonium chloride ama zinc chloride xal biyood ama ammonium chloride iyo zinc chloride haanta xalka biyaha ee isku dhafan si loo nadiifiyo, ka dibna lagu shubo haanta dahaarka kulul. Galvanization-ka kulul ee lagu shubo wuxuu leeyahay faa'iidooyinka dahaarka isku midka ah, isku dhejinta xooggan iyo cimri dheer oo adeeg ah. Inta badan hababka waqooyiga waxay qaataan habka dib-u-cusboonaysiinta zinc ee tuubada tooska ah ee gariiradda galvanized.

Biibiile qabow galvanized

Tuubooyinka qabow ee galvanized-ka ah waa kuwa koronto lagu dhejiyo, tirada galvanized-ka ah aad bay u yar tahay, kaliya 10-50g/m2, iska caabbinta daxalka ayaa aad uga duwan tuubooyinka kulul ee galvanized-ka ah. Soo saarayaasha tuubooyinka galvanized-ka ee caadiga ah, si loo hubiyo tayada, badankood ma isticmaalaan galvanizing-ka korontada (dahaadhka qabow). Kaliya shirkadaha yaryar ee leh qalab duugoobay ayaa isticmaala galvanizing-ka korontada, dabcan, qiimahoodu waa mid raqiis ah. Mustaqbalka, tuubooyinka galvanized-ka qabow looma oggola in loo isticmaalo tuubooyinka biyaha iyo gaaska.

Tuubo bir ah oo galvanized ah oo kulul lagu dhex qasay

Falgallada jireed iyo kuwa kiimikada ee isku dhafan ayaa ka dhaca inta u dhaxaysa tuubada birta ah iyo qubeyska dhalaalay si loo sameeyo lakab bir ah oo zinc-bir ah oo adag oo leh iska caabin daxaleed. Lakabka birta ah waxaa lagu dhex daray lakabka zinc-ka saafiga ah iyo matrix-ka tuubada birta ah. Sidaa darteed, iska caabinteeda daxalka waa mid xooggan.

Ka dib markii la sameeyay tuubooyinka birta kulul ee galvanized-ka ah sannadihii 1960-meeyadii ilaa 1970-meeyadii, tayada badeecaddu aad ayay u fiicnaatay, 1981 ilaa 1989 waxaa la guddoonsiiyay Wasaaradda Birta ee alaabada tayada sare leh iyo abaalmarinta lacagta qaranka, wax soo saarku sidoo kale wuu kordhay sannado badan, 1993 wax soo saar ka badan 400,000 tan, 1999 wax soo saar ka badan 600,000 tan, waxaana loo dhoofiyaa Koonfur-bari Aasiya, Afrika, Mareykanka, Japan, Jarmalka iyo dalalka iyo gobollada. Tuubooyinka galvanized-ka ee kulul waxaa inta badan loo isticmaalaa tuubooyinka biyaha iyo tuubooyinka gaaska, tilmaamaha caadiga ahna waa +12.5~+102 mm. Ka dib 1990-meeyadii, iyadoo ay ugu wacan tahay fiiro gaar ah oo ay dawladdu u leedahay ilaalinta deegaanka, xakamaynta shirkadaha wasakhowga badan ayaa sii kordheysa, "saddexda qashin" ee ka dhasha soo saarista tuubooyinka galvanized-ka ee kulul-ku-qalooca way adag tahay in la xalliyo, iyadoo ay weheliso horumarinta degdegga ah ee tuubooyinka bir-daxalka ah ee aan miridhku lahayn, tuubooyinka PVC-ga iyo tuubooyinka isku-dhafan, iyo sidoo kale gobolka si loo dhiirrigeliyo isticmaalka agabka dhismaha kiimikada, isticmaalka tuubooyinka birta galvanized waa la xaddiday, taasoo ka dhigaysa horumarinta tuubooyinka alxanka ee kulul-ku-qalooca ah inay si weyn u saameysay Beam iyo limit, tuubo alxanka kulul-ku-qalooca ah ayaa markii dambe si tartiib tartiib ah u soo baxday.

tuubo bir ah oo qabow galvanized

Lakabka zinc-ku waa dahaadh koronto, lakabka zinc-kuna si madax-bannaan ayaa loogu dahaadhay matrix-ka tuubada birta ah. Lakabka zinc-ku waa khafiif, lakabka zinc-kuna si fudud ayuu ugu xiran yahay matrix-ka tuubada birta ah waana mid si fudud looga soo dhici karo. Sidaa darteed, iska caabbinta daxalka waa mid liidata. Dhismayaasha cusub ee guryaha la dego, waa mamnuuc in tuubooyinka birta ah ee qabow ee galvanized loo isticmaalo tuubooyinka biyaha.
