Calaamadaha Alaabta

Dulmar guud oo ku saabsan saxanka birta ah ee la calaamadeeyay

Qaabku wuxuu inta badan door ka ciyaaraa ka hortagga simbiriirixanka iyo qurxinta. Saamaynta dhammaystiran ee saxanka simbiriirixanka ee isku dhafan marka la eego awoodda ka hortagga simbiriirixanka, iska caabbinta foorarsiga, keydinta birta iyo muuqaalka ayaa si cad uga wanaagsan kan saxanka simbiriirixanka keliya.

Taarikada birta ah ee la jajabiyey ayaa si weyn loogu isticmaalaa dhismaha maraakiibta, kuleyliyeyaasha, baabuurta, cagaf-cagafyada, baabuurta tareenka iyo warshadaha dhismaha.

Isticmaalka saxanka birta ah ee la calaamadeeyay

Iyada oo ay ugu wacan tahay meelaha dhaadheer ee dusha sare, saxanka birta ah ee qaabaysan wuxuu leeyahay saameyn ka hortagta simbiriirixan, waxaana loo isticmaali karaa dabaqyo, jaranjaro aqoon-is-weydaarsi, baaldiyo shaqo, sagxadyo maraakiibta, taarikada hoose ee gaariga, iwm. Saxanka birta ah ee qaabaysan waxaa loo isticmaalaa aqoon-is-weydaarsiyada, qalabka waaweyn ama meelaha lagu socdo ee maraakiibta iyo jaranjarooyinka. Waa saxan bir ah oo leh qaab dheeman ama qaab digir ah oo dusha sare laga soo saaray.

Heerarka la xiriira iyo darajooyinka taarikada birta ah ee la calaamadeeyay

Waxaa jira heerar badan oo loogu talagalay saxannada birta ee la calaamadeeyay. Waxaa badanaa loo isticmaalaa saxanka birta ee qaabka GB/T 3277-1991, saxanka birta ee qaabka kulul ee la duuduubay ee YB/T 4159-2007 iyo suunka birta, saxanka birta ee qaabka kulul ee la duuduubay ee Q/BQB 390-2014 iyo suunka birta. Waxaa jira saxanno bir ah oo badan oo ah saxanno bir ah oo la calaamadeeyay oo ku jira heer kasta. Tirada badeecada ee saxanka birta ee la calaamadeeyay waxay ku salaysan tahay lambarka saxanka ee substrate-ka oo lagu daray "H-", sida H-Q195, H-Q235B iwm. Kuwaas waxaa ka mid ah, "H" waa xarafka ugu horreeya ee "qaabka" pinyin ee Shiinaha.

Shuruudaha farsamo ee saxan bir ah oo la hubiyay

Shuruudaha farsamo ee saxanka birta ah ee la hubiyay waxaa inta badan loo qaybiyaa 2 qaybood: [substrate] iyo [qaab].

● Shuruudaha dhulka hoostiisa
Iyada oo ku saleysan walxaha kala duwan ee substrate-ka, alaabada saxanka birta ee la hubiyay waxaa loo qaybin karaa afar taxane:
Birta qaab-dhismeedka kaarboonka: GB/T 700 darajooyin dhexdhexaad ah sida Q195, Q215, Q235, iwm.;
Birta xoogga sare leh ee daawaha hooseeya: GB/T 1591 tirada sida Q345;
bir qaab-dhismeed oo loogu talagalay qolofka: GB 712 A, B, D, E iyo darajooyinka kale ee birta;
Birta qaab-dhismeedka cimilada sare leh: Darajooyinka GB/T 4171 waa Q295GNH, Q235NH, iwm.
Fiiro gaar ah: Haddii heerka saxanka birta ah ee la hubiyay uu yahay "H-", halabuurka kiimikada ayaa noqon doona heerka u dhigma ee substrate-ka. Tusaale ahaan, halabuurka kiimikada ee H-Q235B wuxuu la mid yahay kan Q235B. Haddii uu yahay nooc aan lahayn H, xeerarka faahfaahsan waxay u baahan yihiin inay tixraacaan heerka u dhigma.

● Shuruudaha qaab-dhismeedka
Waxaa jira qaabab badan oo qaabab ah, sida misir, digir wareegsan, dheeman, iwm. Marka laga hadlayo qaababka lentil, dulqaadka dhumucda iyo dhererka la oggol yahay ee hadhuudhka ayaa si faahfaahsan loo qeexay.

Waxaan bixinaa Taarikada Chequered Steel ee tayada ugu fiican oo ay soo iibsadaan khubaro tayo leh oo ka socda ilo wanaagsan. Taarikada Chequered-ka ee aan bixinno waa kuwo la isku halleyn karo oo waara. Taarikada Chequered-ka ee aan bixinno aad ayaa loo dalbadaa waxaana laga heli karaa qiimo tartan ah annaga. Waxaan u sameynay boos annaga oo ah mid ka mid ah Alaab-qeybiyeyaasha Taarikada Chequered-ka ee caanka ah ee Imaaraadka Carabta oo loogu talagalay Jirka Sariirta Fidsan, Jiid-jiidayaasha, Gawaarida Xamuulka qaada iyo isticmaalka ganacsiga.
