Waa maxay heerarka darajooyinka ee goobta 00-fasalka imtixaanka granite?

Goobta 00-fasalka tijaabada granite waa qalab cabbiraadda saxda ah, iyo heerarkeeda darajooyinka ayaa ugu horreyn daboolaya dhinacyada soo socda:

Saxnaanta joomatari:

Flatness: Khaladka fidsan ee dhammaan dusha sare ee madalku waa inuu ahaadaa mid aad u yar, sida caadiga ah loo xakameeyo ilaa heerka micron. Tusaale ahaan, xaaladaha caadiga ah, leexashada flatness waa in aanay ka badnayn 0.5 microns, taasoo la micno ah in dusha madal waa ku dhowaad gebi ahaanba siman, bixinta tixraac deggan ee cabbirka.

Isbarbar-dhigga: Isbarbardhigga aadka u sarreeya ayaa loo baahan yahay inta u dhexeysa sagxadaha shaqada ee kala duwan si loo hubiyo saxnaanta cabbirka. Tusaale ahaan, khaladka isbarbardhigga ah ee u dhexeeya labada dusha sare ee shaqada ee isku xigta waa in uu ka yaraado 0.3 microns si loo hubiyo isku halaynta xogta marka la cabbirayo xaglaha ama boosaska xiga.

Shaqsi ahaan: Waa in si adag loo kontoroolo farqiga u dhexeeya dusha sare ee shaqada iyo dusha tixraaca. Guud ahaan, weecasho toosan waa in ay ahaataa 0.2 microns, taas oo muhiim u ah codsiyada u baahan cabbir toosan, sida cabbirka isuduwidda saddex-geesoodka ah.

Agabka Alaabta:

Granite: Granite leh qaab-dhismeed labis ah iyo qaab-dhismeed cufan ayaa sida caadiga ah loo isticmaalaa sida walxaha aasaasiga ah. Adaggeeda sare, caabbinta xidhashada heer sare ah, iyo isku xidhka fidinta kulaylka hooseeya waxay hubisaa xasilloonida cabbirka madal iyo iska caabinta qallafsanaanta inta lagu jiro isticmaalka muddada dheer. Tusaale ahaan, granite-ka la doortay waa in uu lahaadaa adkaanta Rockwell ee 70 ama ka badan si loo hubiyo xirashada wanaagsan ee madal iyo iska caabin xoqan.

Xasilloonida: Goobaha 00-fasalka granite ee tijaabinta waxay maraan daweyn adag oo gabowga inta lagu jiro wax soo saarka si loo baabi'iyo walaacyada gudaha, hubinta waxqabadka xasilloon ee xaaladaha deegaanka ee kala duwan. Daawaynta ka dib, heerka isbeddelka cabbirka madalku kama badna 0.001 mm/m sannadkii, isagoo buuxinaya shuruudaha cabbirka saxda ah.

Tayada dusha sare:

Qallafsanaanta: Qalafsanaanta dusha sare ee madalku aad ayuu u hooseeyaa, caadi ahaan waxa ka hooseeya Ra0.05, taas oo keentay siman muraayad u eg. Tani waxay yaraynaysaa khilaafka iyo khaladka u dhexeeya qalabka wax lagu cabbiro iyo shayga la cabbirayo, si loo hagaajiyo saxnaanta cabbirka.

Gloss: Dhallaanka sare ee madal, sida caadiga ah ka sarreeya 80, kaliya ma wanajiyo bilicdeeda laakiin sidoo kale waxay fududaysaa kormeerida hawlwadeenka natiijooyinka cabbirka iyo hagaajinta.

Xasiloonida Saxda ah ee cabbirka:

Degganaanshaha Heerkulka: Sababtoo ah cabbiradu waxay inta badan u baahan yihiin hawlgal heerkul kala duwan ah, goobta tijaabada granite ee 00-grade ah waa inay muujisaa xasilloonida heerkulka wanaagsan. Guud ahaan, saxnaanta cabbiraadda madalku waa in aanay ku beddelmin in ka badan 0.1 microns marka loo eego heerkulka u dhexeeya -10°C ilaa +30°C, iyada oo la hubinayo in natiijooyinka cabbirka saxda ah ee dhammaan xaaladaha heerkulka.

Xasillooni-dheer: Saxnaanta cabbiraadda madalku waa in ay ahaato mid deggan isticmaalka muddada dheer, iyo ka dib muddada isticmaalka, saxnimadeedu waa in aanay ka duwanayn xadka la cayimay. Tusaale ahaan, xaaladaha shaqada ee caadiga ah, saxnaanta cabbirka madalku waa in aanay ka leexan wax ka badan 0.2 microns muddo hal sano ah.

Marka la soo koobo, heerarka darajooyinka 00-fasalka dhufeysyada granite ee tijaabinta waa kuwo aad u adag, oo daboolaya dhinacyo badan oo ay ku jiraan saxnaanta joomatari, sifooyinka alaabta, tayada dusha sare, iyo cabbiraadda xasiloonida saxnaanta. Kaliya marka la buuxiyo heerarkan sare waxay madalku ka ciyaari kartaa doorkeeda muhiimka ah ee cabbirka saxda ah ee saxda ah, bixinta cabbir sax ah oo la isku halayn karo ee cilmi-baarista sayniska, tijaabada injineernimada, iyo ilaalinta tayada.
