Waa maxay heerarka qiimaynta ee madal tijaabo granite ah oo 00-fasalka ah?

Madal tijaabinta granite-ka heerka 00 waa qalab cabbir sax ah oo heer sare ah, heerarka qiimeyntiisuna waxay inta badan daboolayaan dhinacyada soo socda:

Saxnaanta Joomatari:

Fidsanaan: Khaladka fidsanaan ee dusha sare ee goobta oo dhan waa inuu ahaadaa mid aad u yar, oo caadi ahaan la xakameeyo ilaa heerka micron. Tusaale ahaan, xaaladaha caadiga ah, leexashada fidsanaantu waa inaysan ka badnaan 0.5 microns, taasoo la macno ah in dusha sare ee goobta ay ku dhowdahay inay gebi ahaanba siman tahay, taasoo bixinaysa tixraac deggan oo lagu cabbiro.

Isbarbardhigid: Isbarbardhigid aad u sarreeya ayaa loo baahan yahay inta u dhaxaysa dusha shaqada ee kala duwan si loo hubiyo saxnaanta cabbirka. Tusaale ahaan, qaladka isbarbardhigga ee u dhexeeya laba dusha shaqada ee isku xiga waa inuu ka yar yahay 0.3 microns si loo hubiyo isku halaynta xogta marka la cabbirayo xaglaha ama jagooyinka qaraabada ah.

Joogsi: Joogsi u dhexeeya dusha shaqada kasta iyo dusha tixraaca waa in si adag loo xakameeyaa. Guud ahaan, leexashada toosan waa inay ahaataa gudaha 0.2 microns, taas oo muhiim u ah codsiyada u baahan cabbir toosan, sida cabbirka isku-dubaridka saddex-geesoodka ah.

Sifooyinka Agabka:

Granite: Granite oo leh qaab-dhismeed isku mid ah iyo qaab-dhismeed cufan ayaa badanaa loo isticmaalaa agabka saldhigga ah. Adkaynteeda sare, iska caabinta xirashada aadka u fiican, iyo isku-darka ballaarinta kulaylka oo hooseeya waxay hubiyaan xasilloonida cabbirka goobta iyo iska caabbinta isbeddelka inta lagu jiro isticmaalka muddada dheer. Tusaale ahaan, granite-ka la doortay waa inuu lahaadaa adkaanta Rockwell oo ah 70 ama ka badan si loo hubiyo iska caabbinta xoqidda iyo xoqidda ee goobta.

Xasilloonida: Goobaha tijaabada granite-ka ee heerka 00-aad waxaa la mariyaa daaweyn gabowga oo adag inta lagu jiro wax soo saarka si loo baabi'iyo walbahaarka gudaha, taasoo hubinaysa waxqabad deggan xaaladaha deegaanka ee kala duwan. Daaweynta ka dib, heerka isbeddelka cabbirka ee goobta kama badna 0.001 mm/m sannadkii, taasoo buuxinaysa shuruudaha cabbirka saxnaanta sare leh.

Tayada Dusha Sare:

Qalafsanaanta: Qalafsanaanta dusha sare ee madalku aad ayay u hooseysaa, badanaa waxay ka hooseysaa Ra0.05, taasoo keenta siman u eg muraayad. Tani waxay yareysaa is jiidjiidka iyo khaladaadka u dhexeeya qalabka cabbiraadda iyo shayga la cabbirayo, taasoo hagaajineysa saxnaanta cabbirka.

Dhalaalaya: Dhalaalayasha sare ee madalku, oo badanaa ka sarreeya 80, ma aha oo kaliya inay kor u qaaddo bilicdeeda laakiin sidoo kale waxay sahlaysaa u kuurgalka hawlwadeenka natiijooyinka cabbirka iyo hagaajinta.

Xasiloonida Saxnaanta Cabbirka:

Xasiloonida Heerkulka: Maadaama cabbiraadaha badanaa ay u baahan yihiin hawlgal jawi heerkul oo kala duwan, goob tijaabo ah oo granite ah oo 00-heer ah waa inay muujisaa xasillooni heerkul oo aad u fiican. Guud ahaan, saxnaanta cabbirka goobta waa inaysan ku kala duwanaan wax ka badan 0.1 microns heerkul u dhexeeya -10°C ilaa +30°C, taasoo hubinaysa natiijooyinka cabbirka saxda ah ee xaaladaha heerkulka oo dhan.

Xasilloonida Muddada Dheer: Saxnaanta cabbirka madalku waa inay ahaataa mid deggan inta lagu jiro isticmaalka muddada dheer, ka dib marka la isticmaalo, saxnaanteedu waa inaysan ka duwanaan xadka la cayimay. Tusaale ahaan, xaaladaha caadiga ah ee hawlgalka, saxnaanta cabbirka madalku waa inaysan ka leexan wax ka badan 0.2 microns muddo hal sano ah.

Marka la soo koobo, heerarka qiimaynta ee goobaha tijaabada granite-ka ee heerka 00-aad waa kuwo aad u adag, oo daboolaya dhinacyo badan oo ay ku jiraan saxnaanta joomatari, sifooyinka agabka, tayada dusha sare, iyo xasilloonida saxnaanta cabbirka. Kaliya marka la buuxiyo heerarkan sare ayaa madalku ka ciyaari kartaa doorkeeda muhiimka ah ee cabbirka saxnaanta sare, iyadoo bixinaysa halbeeg cabbir oo sax ah oo lagu kalsoonaan karo oo loogu talagalay cilmi-baarista sayniska, tijaabinta injineernimada, iyo xakamaynta tayada.
