Nangona ukusetyenziswa kwe-carbon steel rebar kwanele kwiiprojekthi ezininzi zokwakha, kwezinye iimeko, ikhonkrithi ayinakubonelela ngokhuseleko lwendalo olwaneleyo. Oku kuyinyani ngakumbi kwiindawo zaselwandle nakwiindawo apho kusetyenziswa khona ii-deicing agents, nto leyo enokubangela ukubola okubangelwa yi-chloride. Ukuba ii-stainless steel threaded bars zisetyenziswa kwiindawo ezinjalo, nangona utyalo-mali lokuqala luphezulu, zinokwandisa ubomi besakhiwo kwaye zinciphise iimfuno zolondolozo, ngaloo ndlela zinciphisa iindleko zexesha elide.
Kutheni usebenzisa intsimbi engagqwaliyoi-rebar?
Xa ii-ion ze-chloride zingena kwikhonkrithi eqinisiweyo yentsimbi yekhabhoni zize zihlangane nentsimbi yekhabhoni, i-rebar yentsimbi yekhabhoni iya kubola, kwaye iimveliso zokubola ziya kwanda kwaye zande, nto leyo ebangela ukuqhekeka nokuxobuka kwekhonkrithi. Ngeli xesha, kufuneka kwenziwe ulondolozo.
I-rebar yentsimbi yekhabhoni inokumelana kuphela nomxholo we-chloride ion ofikelela kwi-0.4%, ngelixa intsimbi engatyiwayo inokumelana nomxholo we-chloride ion ofikelela kwi-7%. Intsimbi engatyiwayo iphucula ubomi benkonzo yesakhiwo kwaye inciphisa iindleko zokugcinwa nokulungiswa.
Zithini iingenelo zentsimbi engagqwaliyoi-rebar?
1. Inokumelana okuphezulu nokugqwala kwe-chloride ion
2. Ukungaxhomekeki kwi-alkalinity ephezulu yekhonkrithi ukukhusela imivalo yentsimbi
3. Ngaba inganciphisa ubukhulu bomaleko wokukhusela wekhonkrithi
4. Akukho mfuneko yokusebenzisa isitywina sekhonkrithi esifana ne-silane
5. Ukuxuba ikhonkrithi kungenziwa lula ukuhlangabezana neemfuno zoyilo lwesakhiwo, ngaphandle kokuqwalasela ukukhuselwa kweentsimbi zentsimbi.
6. Ukuphucula kakhulu ukuqina kwesakhiwo
7. Zinciphisa kakhulu iindleko zokulungisa nokugcina izinto zisemgangathweni
8. Nciphisa iindleko zokungasebenzi kunye neendleko zokulungisa zemihla ngemihla
9. Ingasetyenziswa ngokukhethekileyo kwiindawo ezinobungozi obukhulu
10. Ekugqibeleni inokuphinde isetyenziswe ukuze ivuselelwe
Intsimbi engagqwaliyo iyenza ninii-rebarkufuneka isetyenziswe?
Xa isakhiwo sichaphazeleka kwii-ion ze-chloride eziphezulu kunye/okanye kwiindawo zoshishino ezirhabaxa
Iindlela kunye neebhulorho ezisebenzisa iityuwa zokucoca
Xa kufuneka (okanye kufunwa) ukuba i-rebar yentsimbi ingabi yimagnethi
Intsimbi engagqwali kufuneka ibekwe phii-rebaringasetyenziswa?
Ukulungiswa kwentsimbi engagqwaliyo kufuneka kuqwalaselwe kwezi meko zilandelayo
1. Indalo eyonakalisayo
Iindawo zokumisa iibhulorho, iidokhi, ii-trestles, ii-blockwaters, iindonga zolwandle, iintsika zokukhanya okanye iirelingi, iibhulorho zeendlela ezinkulu, iindlela, ii-overpasses, ii-overpasses, iindawo zokupaka, njl.njl. emanzini olwandle, ingakumbi kwiindawo ezishushu.
2. Isityalo sokukhupha ityuwa emanzini olwandle
3. Iindawo zokunyanga amanzi amdaka
4. Izakhiwo ezihlala ixesha elide ezifana nokulungiswa kwezakhiwo zembali kunye neendawo zokugcina inkunkuma yenyukliya ziyafuneka
5. Iindawo ezisengozini yokunyikima, njengoko izakhiwo zekhonkrithi eziqinisiweyo zinokuwa ngexesha lokunyikima ngenxa yokugqwala
6. Iipaseji kunye neetonela ezingaphantsi komhlaba
7. Iindawo ezingenakuhlolwa okanye ezingenakulungiseka ukuze zilungiswe
Indlela yokusebenzisa intsimbi engagqwaliyoi-rebar?
Kumazwe angaphandle, i-stainless steel rebar yenziwa ngokuyintloko ngokwemigangatho yaseBritane i-BS6744-2001 kunye nemigangatho yaseMelika i-ASTM A 955/A955M-03b. IFrance, i-Itali, iJamani, iDenmark, kunye neFinland nazo zinemigangatho yazo yesizwe.
ETshayina, umgangatho we-stainless steel rebar yi-YB/T 4362-2014 “I-stainless steel rebar yekhonkrithi eqinisiweyo”.
Ububanzi be-rebar yentsimbi engagqwaliyo yi-3-50 millimeters.
Amanqanaba afumanekayo aquka intsimbi engagqwaliyo ephindwe kabini 2101, 2304, 2205, 2507, intsimbi engagqwaliyo e-austenitic 304, 316, 316LN, 25-6Mo, njl.
