Haddii 55% aluminium-zinc dahaarka dahaarka leh Galvalume birta ay ka jilicsan tahay birta Galvanized

Maxay tahay sababta xaashida birta ee Aluzinc loogu arki karaa inay ka yara jilicsan tahay xaashida galvanized? Changzhou Jiaye wuxuu sharxayaa dhacdadan isagoo baaraya ka kooban walxaha, qaab dhismeedka daahan, iyo sifooyinka farsamada.

"Jilicsan" caadi ahaan waxa loola jeedaa xoogga wax-soo-saarka hoose ama qiyamka qallafsanaanta. Si kastaba ha ahaatee, waxaa muhiim ah in la ogaado in codsiyada injineernimada dhabta ah, aragtida "jilicsanaan" ama "engeganaanta" inta badan waxay ka timaadaa habdhaqanka habdhaqanka - sida guga ugu yar inta lagu jiro foorarsiga ama fududaynta qaabaynta - halkii ay ka ahaan lahayd qiyamka adag ee dhamaystiran. Natiijooyinka raadinta si toos ah uma tilmaamayaan in adkaanta guud ee xaashida birta Aluzinc ay ka hooseyso tan xaashida birta galvanized; Taas beddelkeeda, ilo badan ayaa xooga saaraya *xooggiisa sare*, halka xogta ku saabsan qiyamka qalafsanaantu ay weli tahay mid yar ama iska hor imanaysa.

Xaashiyaha birta ee Aluzinc maaha mid caalami ah "jilicsan"; Dhab ahaantii, xaaladaha intooda badan, waxay leedahay awood wax-soosaar sare. Fikradda ah in ay "jilicsan tahay" waa fikrad khaldan; Balse, waa muujinta qaabaynteeda aadka u wanaagsan, dib-u-soo-celinta ugu yar, iyo ductility sare.

Isbarbardhigga sifooyinka farsamada ayaa si cad u muujinaya inay ka xoog badan tahay:

DC51D+AZ Aluzinc sheet steel (150g/m²) waxa ay muujisaa wax-soo-saarka 230-400 MPa, halka heerka u dhigma ee xaashida birta galvanized (DC51D) u dhaxaysa 140-300 MPa. Xoogeeda xajinta ayaa sidoo kale ka sareysa (230-550 MPa vs. 200-330 MPa). Tani waxay tusinaysaa iska caabin wayn oo ka imanaysa qallafsanaanta balaastikada, taasoo muujinaysa inaanay * ka jilicsanayn.

Waxa jira saddex sababood oo asaasi ah oo ka dambeeya *aragtida* "jilicsanaanta":

Ductility Sare: Heerka fidinta xaashida birta ee Aluzinc waxay gaari kartaa 15-45%, taas oo ka sarraysa 13-25% inta u dhaxaysa xaashida galvanized. Taas macnaheedu waa si fudud ayaa loo kala fidiyaa oo loo foorarsadaa iyada oo aan dillaacin.

Dib-u-soo-celinta Hoose: Sababtoo ah isku-xidhka cufan ee u dhexeeya daahan iyo birta saldhigga ah (oo loo aanaynayo qaab-dhismeedkeeda crystalline quaternary), maaddadu waxay si fiican u haysaa qaabkeeda ka dib foorarsiga. Hawl-wadeenadu waxay si khaldan u fasiri karaan "fududeynta qaabaynta" iyo la'aanta "iska caabinta" jilicsan.

Astaamaha dusha sare: Aluzinc waxa uu leeyahay midab qalin-cad, oo siman oo leh qaab "spangle" kala duwan. Qoraalkeeda wanaagsan ee taabashada waxay u horseedi kartaa aragti muuqaal ah iyo xukun taabasho leh oo ah in maaddadu ay "jilicsan tahay" - dhalanteed jireed oo keliya. Aluminium-zinc sheet bir ah ma aha mid jilicsan; balse, waxay isku daraysaa xoog sare iyo ductility heer sare ah, iyada oo u kala saaraysa wax "xoog leh haddana adag". "Jilicsanaanta" ay garteen isticmaalayaashu, dhab ahaantii, waxay ka tarjumaysaa sifooyinkeeda saaxiibtinimo-gaar ahaan, qaabaynteeda gaarka ah, dib u soo noqoshada ugu yar, iyo dhererka sare. Markaad dooranayso alaabta, birta aluminium-zinc waxay bixisaa faa'iidooyin kala duwan codsiyada ku lug leh foorarsiga soo noqnoqda, sawir qoto dheer, ama halka xasilloonida cabbirka ay tahay mudnaanta.

Marka la soo koobo, doorashada u dhaxaysa birta aluminium-zinc iyo birta galvanized waa in lagu go'aamiyaa qiimeyn dhamaystiran oo shuruudaha kala duwan, oo ay ku jiraan codsiga loogu talagalay alaabta la dhammeeyey, baahiyaha iska caabinta cimilada, iyo caqabadaha miisaaniyadda.
