Chii chinonzi Stainless Steel Rebar?

Kunyangwe kushandiswa kwesimbi yekabhoni kwakakwana mumapurojekiti mazhinji ekuvaka, mune dzimwe nguva, kongiri haigone kupa dziviriro yakakwana yechisikigo. Izvi zvinonyanya kuitika kune nharaunda dzemugungwa nenzvimbo dzinoshandiswa zvinhu zvinobvisa mvura, izvo zvinogona kukonzera ngura inokonzerwa nechloride. Kana simbi dzisina ngura dzakashandiswa munzvimbo dzakadaro, kunyangwe mari yekutanga iri yakakwira, dzinogona kuwedzera hupenyu hwechivakwa uye kuderedza zvinodiwa pakugadzirisa, nokudaro zvichideredza mari yenguva refu.

Sei uchishandisa simbi isina ngurabhaa rekare?

Kana maion echloride akapinda mukongiri yakasimbiswa nesimbi yekabhoni uye akasangana nesimbi yekabhoni, simbi yekabhoni inozoora, uye zvigadzirwa zvengura zvinokura uye zvinokura, zvichikonzera kutsemuka nekubviswa kwekongiri. Panguva ino, kugadziriswa kunofanirwa kuitwa.

Kabhoni simbi rebar inogona kutsungirira kusvika ku0.4% yechloride ion, nepo simbi isina ngura inogona kutsungirira kusvika ku7% yechloride ion. Simbi isina ngura inovandudza hupenyu hwebasa rechivakwa uye inoderedza mari yekugadzirisa nekugadzirisa.

Ndezvipi zvakanakira simbi isina ngura?bhaa rekare?

1. Inodzivirira zvakanyanya chloride ion corrosion

2. Kusavimba ne alkalinity yakawanda yekongiri kuchengetedza simbi

3. Inogona kuderedza ukobvu hwekongiri inodzivirira

4. Hapana chikonzero chekushandisa simende sechisimbiso senge silane

5. Kusanganiswa kwekongiri kunogona kurerutswa kuti kugutse zvinodiwa pakugadzirwa kwechivako, pasina kufunga nezvekuchengetedzwa kwesimbi.

6. Kuvandudza zvakanyanya kugara kwenguva refu kwechivakwa

7. Kuderedza zvakanyanya mari yekugadzirisa nekugadzirisa

8. Deredza mari yekuzorora uye yekugadzirisa zuva nezuva

9. Inogona kushandiswa nenzira yakasarudzika munzvimbo dzine njodzi huru

10. Pakupedzisira inogona kushandiswazve kuti idzokorore

Simbi isingasvibiki inogadzirwa riinibhaa rekareinofanira kushandiswa here?

Kana chivakwa chacho chikasangana nemaion ane chloride yakawanda uye/kana nharaunda dzemaindasitiri dzinoparadza

Migwagwa nemabhiriji uchishandisa munyu wekuchenesa

Kana zvichidikanwa (kana zvichidikanwa) kuti simbi isashande semagineti

Simbi isina ngura inofanira kupibhaa rekarekushandiswa here?

Kugadziriswa kwesimbi isina ngura kunofanirwa kufungwa nezvako mumamiriro ezvinhu anotevera

1. Nzvimbo inoparadza

Nzvimbo dzekumisikidza mabhiriji, madoko, nzvimbo dzekumisa migwagwa, nzvimbo dzinodzivirira migwagwa, masvingo egungwa, makomba emwenje kana njanji, mabhiriji emigwagwa mikuru, migwagwa, nzvimbo dzinopfuura migwagwa, nzvimbo dzinopfuura migwagwa, nzvimbo dzinopakira mota, nezvimwewo mumvura yegungwa, kunyanya munzvimbo dzinopisa.

2. Chivako chekubvisa munyu mumvura yegungwa

3. Nzvimbo dzekuchenesa tsvina

4. Zvivako zvekuvaka zvinogara kwenguva refu zvakaita sekugadziriswa kwezvivakwa zvekare nenzvimbo dzekuchengetera marara enyukireya zvinodiwa

5. Nzvimbo dzinowanzo kanganiswa nekudengenyeka kwenyika, sezvo zvivakwa zvekongiri zvakasimbiswa zvinogona kudonha panguva yekudengenyeka kwenyika nekuda kwengura

6. Nzira dzepasi pevhu nematunera

7. Nzvimbo dzisingakwanise kuongororwa kana kutarisirwa kuti dzigadziriswe

Mashandisirwo esimbi isina ngurabhaa rekare?

Munyika dzekunze, simbi isina ngura inogadzirwa zvakanyanya zvichienderana nechiyero cheBritain cheBS6744-2001 uye chiyero cheAmerica cheASTM A 955/A955M-03b. France, Italy, Germany, Denmark, neFinland vanewo zviyero zvavo zvenyika.

MuChina, chiyero che stainless steel rebar ndeche YB/T 4362-2014 "Stainless steel rebar yekongiri yakasimbiswa".

Dhayamita yesimbi isina ngura ndeye 3-50 millimeters.

Magiredhi aripo anosanganisira duplex stainless steel 2101, 2304, 2205, 2507, austenitic stainless steel 304, 316, 316LN, 25-6Mo, nezvimwewo.
