Kanaallada C ee Birta aan Daxalka lahayn
Sharaxaad Gaaban:
Kanaallada birta aan lahayn waa qaybo qaab-dhismeed oo laga sameeyay bir aan lahayn, oo ah daxal u adkaysta daxalka oo inta badan ka kooban bir, chromium, nikkel, iyo walxo kale.
Kanaalada Birta aan Daxalka lahayn:
Kanaallada birta aan lahayn waa astaamo qaab-dhismeed oo laga sameeyay birta aan lahayn ee aan lahayn daxalka, oo leh isgoys C-qaabaysan ama U-qaabaysan, oo ku habboon codsiyada dhismaha, warshadaha, iyo deegaannada badda. Caadiyan waxaa lagu soo saaraa hababka duubista kulul ama qabowga, waxay bixiyaan iska caabin daxalka oo aad u fiican iyo taageero qaab-dhismeed, oo si weyn loogu isticmaalo dhismaha qaababka, qalabka wax soo saarka, injineernimada badda, iyo codsiyada kale ee kala duwan. Iyada oo ku xidhan qeexitaannada ay dejiyeen heerarka sida ASTM, EN, iwm., darajooyin bir ah oo aan lahayn daxalka oo kala duwan sida 304 ama 316 ayaa la dooran karaa si loo daboolo shuruudaha gaarka ah ee mashruuc la bixiyay. Kanaallada birta aan lahayn daxalka waxay yeelan karaan dhammaystir dusha sare oo kala duwan, sida dhammaystir la safeeyey, la cadayay, ama warshad, iyadoo ku xidhan codsiga loogu talagalay iyo shuruudaha bilicda.

Sidee loo leexiyaa kanaalka birta aan lahayn?
Laabista kanaalada birta aan miridhku lahayn waxay u baahan tahay isticmaalka qalab iyo habab ku habboon. Ku bilow inaad calaamadiso meelaha laalaaban ee kanaalka oo aad si adag ugu xirto mashiinka laalaaban ama bareegga riix. Hagaaji dejimaha mashiinka, samee qalooc tijaabo ah si loo hubiyo saxnaanta, oo sii wad qaloocinta dhabta ah, si dhow ula soco habka oo hubi xagasha leexashada. Ku celi habka meelo badan oo laalaaban, samee taabasho kasta oo loo baahdo sida nadiifinta, oo raac tilmaamaha badbaadada adigoo xiranaya qalab ilaalin shaqsiyeed oo habboon inta lagu jiro hawsha.
Waa maxay codsiyada kanaalka birta aan daxalka lahayn?
Birta kanaalka waa walax qaab-dhismeed oo kala duwan oo si weyn loogu isticmaalo dhismaha, wax soo saarka, baabuurta, badda, tamarta, gudbinta korontada, injineernimada gaadiidka, iyo wax soo saarka alaabta guriga. Qaabkeeda gaarka ah, oo ay weheliso xoog sare iyo iska caabinta daxalka, ayaa ka dhigaysa doorasho ku habboon dhismaha qaab-dhismeedka, qaab-dhismeedka taageerada, mashiinnada, shasigga baabuurta, kaabayaasha tamarta, iyo alaabta guriga. Birta kanaalka birta ah ee aan miridhku lahayn waxaa badanaa loo isticmaalaa waaxaha kiimikada iyo warshadaha si loo soo saaro taageerooyinka qalabka iyo xirmooyinka dhuumaha, taasoo muujinaysa muhiimaddeeda warshadaha kala duwan.
Waa maxay dhibaatooyinka la xiriira xagasha laabashada ee kanaalka?
Dhibaatooyinka xagasha leexashada ee kanaalada birta aan miridhku lahayn waxaa ka mid noqon kara khaladaad, foorarsi aan sinnayn, qallooca agabka, dildilaaca ama jabitaanka, dib u soo kabashada, xirashada qalabka, cilladaha dusha sare, adkaanta shaqada, iyo wasakheynta qalabka. Dhibaatooyinkani waxay ka imaan karaan arrimo ay ka mid yihiin dejinta mashiinka khaldan, kala duwanaanshaha agabka, xoog xad dhaaf ah, ama dayactirka qalabka oo aan ku filnayn. Si wax looga qabto arrimahan, waxaa muhiim ah in la raaco hababka leexashada saxda ah, la isticmaalo qalabka ku habboon, si joogto ah loo ilaaliyo qalabka, iyo in la hubiyo in habka leexashada uu la jaanqaado heerarka warshadaha, iyadoo la yareynayo khatarta ah in la wiiqo tayada, saxnaanta, iyo hufnaanta qaab-dhismeedka kanaallada birta aan miridhku lahayn.
