Iyini i-Stainless Steel Rebar?

Nakuba ukusetshenziswa kwe-carbon steel rebar kwanele kumaphrojekthi amaningi wokwakha, kwezinye izimo, ukhonkolo awukwazi ukunikeza ukuvikelwa kwemvelo okwanele.Lokhu kuyiqiniso ikakhulukazi ezindaweni zasolwandle kanye nezindawo lapho kusetshenziswa khona ama-deicing agents, okungaholela ekugqwaleni okubangelwa i-chloride.Uma izinsimbi zensimbi ezingenasici zisetshenziswa ezindaweni ezinjalo, nakuba ukutshalwa kwezimali kokuqala kuphezulu, zinganweba isikhathi sokuphila kwesakhiwo futhi zinciphise izidingo zokunakekela, ngaleyo ndlela zinciphise izindleko zesikhathi eside.

Kungani usebenzise insimbi engagqwalirebar?

Lapho ama-ion e-chloride engena kukhonkolo yensimbi eqinisiwe futhi ehlangana ne-carbon steel, i-carbon steel rebar izogqwala, futhi imikhiqizo yokugqwala izokwanda futhi inwebeke, ibangele ukuqhekeka nokuxebuka kukakhonkolo.Ngalesi sikhathi, ukunakekelwa kufanele kwenziwe.

I-Carbon steel rebar ingamelana kuphela nokuqukethwe kwe-ion ye-chloride kufika ku-0.4%, kuyilapho insimbi engagqwali ingamelana nokuqukethwe kwe-ion ye-chloride kufika ku-7%.Insimbi engagqwali ithuthukisa impilo yesevisi yesakhiwo futhi inciphisa izindleko zokulungisa nokulungisa

Yiziphi izinzuzo zensimbi engagqwalirebar?

1. Inokumelana okuphezulu ne-chloride ion corrosion

2. Ukungathembeli ku-alkalinity ephezulu kakhonkolo ukuvikela imigoqo yensimbi

3. Inganciphisa ukushuba kongqimba oluvikelayo lukakhonkolo

4. Asikho isidingo sokusebenzisa i-concrete sealant njenge-silane

5. Ukuxuba ukhonkolo kungenziwa lula ukuze kuhlangatshezwane nezidingo zokuklama kwesakhiwo, ngaphandle kokucabangela ukuvikelwa kwezinsimbi zensimbi.

6. Ukuthuthukisa ngokuphawulekayo ukuqina kwesakhiwo

7. Yehlisa ngokuphawulekayo izindleko zokulungisa nokulungisa

8. Yehlisa isikhathi sokuphumula kanye nezindleko zokunakekela nsuku zonke

9. Ingasetshenziswa ngokukhetha ezindaweni ezinobungozi obukhulu

10. Ekugcineni ingaphinda igaywe kabusha ukuze ivuselelwe

Isebenza nini insimbi engagqwalirebarudinga ukusetshenziswa?

Uma isakhiwo sichayeka kuma-ion e-chloride aphezulu kanye/noma izindawo zezimboni ezigqwalayo

Imigwaqo namabhuloho asebenzisa usawoti we-deicing

Lapho kudingekile (noma kufiswa) ukuthi ibha yensimbi ayiyona kazibuthe

Lapho kufanele insimbi engagqwalirebarkusetshenziswe?

I-stainless steel rebar kufanele ibhekwe kulezi zimo ezilandelayo

1. Indawo eyonakalisayo

Ama-anchorage amabhuloho, amadokhi, ama-trestles, ama-breakwaters, izindonga zolwandle, amakholomu okukhanya noma ojantshi, amabhuloho emigwaqo emikhulu, imigwaqo, izindawo ezidlula ngaphezulu, izindawo ezidlula ngaphezulu, izindawo zokupaka, njll. emanzini olwandle, ikakhulukazi ezindaweni ezishisayo

2. Isitshalo sokususa usawoti emanzini olwandle

3. Izikhungo zokuhlanza indle

4. Izakhiwo zokwakha impilo ende njengokubuyiselwa kwezakhiwo zomlando kanye nezindawo zokugcina imfucuza yenuzi ziyadingeka

5. Izindawo ezijwayele ukuzamazama, njengoba izakhiwo zikakhonkolo eziqinisiwe zingadilika ngesikhathi sokuzamazama komhlaba ngenxa yokugqwala.

6. Imigudu engaphansi komhlaba kanye nemigudu

7. Izindawo ezingeke zihlolwe noma zigcinwe ukuze zilungiswe

Indlela yokusebenzisa insimbi engagqwalirebar?

Emazweni angaphandle, i-stainless steel rebar ikhiqizwa ikakhulukazi ngokwezinga laseBrithani i-BS6744-2001 kanye ne-American standard ASTM A 955/A955M-03b.IFrance, i-Italy, iJalimane, iDenmark, neFinland nazo zinezindinganiso zazo kazwelonke.

E-China, indinganiso ye-stainless steel rebar yi-YB/T 4362-2014 “Rebar yensimbi engagqwali yokhonkolo oqinisiwe”.

Ububanzi be-rebar yensimbi engagqwali buyi-3-50 millimeters.

Amamaki atholakalayo afaka i-duplex insimbi engagqwali 2101, 2304, 2205, 2507, austenitic insimbi engagqwali 304, 316, 316LN, 25-6Mo, njll.

Indlela yokuthenga insimbi engagqwalirebar?

I-stainless steel rebar enentambo ekhiqizwe i-zhongao Metal isetshenziswe ngempumelelo kumabhuloho amaningi namaphrojekthi wokwakha ezindaweni ezigqwalile kakhulu.Le migoqo yensimbi inganweba isikhathi sempilo yesakhiwo, inciphise izidingo zokunakekelwa, futhi ngaleyo ndlela inikeze ukusebenza kahle kwezindleko.I-zhongao inesinye sezindawo zokugcina izimpahla ezinkulu kunazo zonke ze-stainless steel rebar e-China, inganikeza imigoqo ngesikhathi esifushane kakhulu.
