Saxanka dusha sare ee granite waa aasaaska cabbirka cabbirka. Waa meesha ugu muhiimsan ee dhammaan cabbiraadaha kale lagu barbar dhigo. Laakiin dhammaan saxamada dusha sare looma abuurin si isku mid ah - mana aha dhammaan heerarka isku mid ah. Haddii aad qeexayso saxan dusha sare ah oo loogu talagalay shaybaarka metrology, waaxda kormeerka, ama xarunta cabbiraadda, fahamka kala duwanaanshaha u dhexeeya heerarka DIN, ASME, iyo JIS ma aha oo kaliya mid tacliimeed. Waa farqiga u dhexeeya iibsashada saxan buuxiya shuruudahaaga iyo iibsashada mid aan buuxin.
Muuqaalka Heerarka
Dhowr heer oo caalami ah ayaa xukuma saxnaanta iyo habaynta saxannada dusha sare ee granite. Kuwa ugu badan ee la tixraacayo waxaa ka mid ah:
- DIN 876 (Heerka Jarmalka), oo daboolaya taarikada dusha sare si loo baaro loona cabbiro
- ASME B89.3.7 (Heerka Mareykanka), kaas oo beddelay GGG-P-463C ee hore ee Tilmaamaha Federaalka
- JIS B 7513 (Heerka Jabbaan), oo daboolaya saxannada dusha sare si loo cabbiro saxnaanta
- GB/T 20428 (Heerka Shiinaha)
- BS 817 (Heerka Ingiriiska)
Heer kastaa wuxuu qeexayaa darajooyin sax ah oo kala duwan, habab tijaabo ah, iyo shuruudaha aqbalaadda. Saxan buuxiya DIN 876 Heerka 00 waxaa laga yaabaa inaanu buuxin ASME B89.3.7 Heerka AA—iyo caksigeeda.
Fahmidda Darajooyinka Saxnaanta
Saxnaanta saxanka dusha sare ee granite waxaa badanaa lagu muujiyaa dulqaadka fidsan ee dusha sare ee saxanka. Waa kan isbarbardhig guud:
| Fasal | Dulqaadka Fidsan ee Caadiga ah | Codsiga Caadiga ah |
|---|---|---|
| DIN 876 Fasalka 00 | ±0.001 mm/m | Tixraaca Shaybaarka, Cabbirka Saxnaanta Sare |
| DIN 876 Fasalka 0 | ±0.002 mm/m | Kormeerka, habaynta |
| ASME B89.3.7 Heerka AA | ±(1.0 + L/250) μm | Cabbiraadda saxda ah ee sare |
| ASME B89.3.7 Heerka A | ±(2.0 + L/250) μm | Kormeer guud |
| Darajada JIS 0 | ±0.003 mm/m | Cabbirka saxda ah |
| Fasalka 1aad ee JIS | ±0.006 mm/m | Kormeerka aqoon-is-weydaarsiga |
L = dhererka saxanka ee xagal-xagal ah oo ah mm
Qodobka ugu muhiimsan ee la qaadan karo: saxanka "Darajada 00" ee hoos yimaada DIN daruuri maaha inuu la mid yahay "Darajada AA" ee hoos timaada ASME. Hababka imtixaanku way kala duwan yihiin, dhibcaha cabbirku way kala duwan yihiin, shuruudaha aqbalaaddana way kala duwan yihiin.
Waxa aad ka raadinayso Saxan Dusha Sare oo Tayo leh
Marka laga soo tago heerka saxnaanta, dhowr arrimood ayaa go'aamiya in saxanka dusha sare uu u shaqeyn doono sidii la filayay inta uu shaqeynayo:
Tayada Agabka. Granite-ku waa inuu ahaadaa mid si fiican loo jarjaray, oo aan lahayn cillado, iyo cufnaan isku mid ah. Granite-ka tayada hooseeya wuxuu ka koobnaan karaa jab yar oo saameeya xasilloonida muddada dheer. ZHHIMG®, waxaan isticmaalnaa granite madow oo ZHHIMG® ah oo leh cufnaan dhan ≈3100 kg/m³—oo ka sarreeya inta badan granite-ka madow ee Yurub iyo Mareykanka—iyadoo la hubinayo xasillooni iyo iska caabin heer sare ah.
Adkaanta iyo iska caabinta xirashada. Saxanka dusha sare waa inuu iska caabiyaa xoqidda iyo xirashada isticmaalka soo noqnoqda. Granite-keennu wuxuu gaaraa adkaanta Mohs ee 6-7, taasoo siinaysa iska caabin xirasho oo aad u fiican tobanaan sano oo isticmaal maalinle ah.
Xasiloonida Kulaylka. CTE-ga granite-ka waa inuu ahaadaa mid hooseeya oo la saadaalin karo intii suurtagal ah. Granite-ka madow ee ZHHIMG® wuxuu bixiyaa xasillooni kuleyl oo heer sare ah, isagoo ilaalinaya fidsanaan heerkulka kala duwan taasoo sababi karta in taarikada birta ahi ay qalloocaan.
Kala-hagaajinta iyo Raad-raaca. Saxanku waa inuu la socdaa shahaado cabbir ah oo dib ugu celinaysa cabbiraadaha machadka cabbirka qaranka. ZHHIMG®, saxan kasta oo dusha sare ah waxaa lagu hagaajiyaa qalab ay shahaado ka haystaan Machadka Metrology-ga Jinan iyo Machadka Metrology-ga Shandong, iyadoo la raacayo raad-raaca Machadka Metrology-ga Qaranka ee Shiinaha.
Doorka Xirfad-yaqaannimada Xirfadda leh
Xitaa granite-ka ugu fiican waxba ma tari karo iyada oo aan si habboon loo dhammaystirin.saxanka dusha sare ee granitewaxay ku lug leedahay laba marxaladood oo aasaasi ah: diyaarinta madhan iyo farsamaynta saxda ah. Meesha bannaan waxaa laga soo gooyaa baloog la qoday, ka dibna si sax ah loo qoday ilaa si qiyaas ah loo qiyaaso si siman. Laakiin tallaabada ugu dambeysa - gaarista heerka si siman ee la cayimay - waxay u baahan tahay gacmo-qabasho xirfad leh.
Farsamoyaqaanno xirfad leh ayaa si taxaddar leh u hagaajiya dusha sare ee saxanka si loo gaaro fidsanaanta iyo simanaanta loo baahan yahay. Qayb kasta waa inay ka gudubtaa kormeer adag si loo xaqiijiyo inay buuxisay heerka la cayimay. ZHHIMG®, makiinadaha shiidayaashayada waaweyn waxay leeyihiin in ka badan 30 sano oo waayo-aragnimo gacan-ku-qabasho ah, iyagoo gaaraya fidsanaan heer micrometer ah iyada oo loo marayo xasaasiyad taabashada ah oo aan mashiinku soo koobi karin.
Talo Wax Ku Ool Ah Iibsadayaasha
Markaad isbarbardhigayso xigashooyinka soo saarayaasha kala duwan, ha ku tiirsanaan magaca agabka oo keliya. Codso:
- Cufnaanta dhabta ah ee granite-ka (ma aha oo kaliya "granite" laakiin nooca gaarka ah iyo cufnaanta)
- CTE (isku-darka ballaarinta kulaylka) oo lagu cabbiray 20°C
- Dulqaadka fidsan ee la gaaray iyo heerka laga cabbiray
- Shahaadada cabbiraadda iyo dukumeentiga raad-raaca
- Dammaanadda nolosha adeegga iyo siyaasadda dib-u-cusboonaysiinta
Haddii alaab-qeybiyuhu aanu bixin karin faahfaahintan, taasi waa calaamad cas. Soo-saarayaal yaryar oo badan ayaa isticmaala marmar raqiis ah halkii ay ka isticmaali lahaayeen granite dhab ah - dhaqan khiyaano ah oo aan si adag uga soo horjeedno. Marmarku waa jilicsan yahay, xasillooni yar yahay, wuxuuna u nugul yahay in la xidho marka loo eego granite-ka saxda ah. Farqigu ma aha mid yar; waa farqiga u dhexeeya saxanka dusha sare ee saxnaanta haysta tobanaan sano iyo mid ka baxa shuruudaha sannado gudahood.
Dayactirka iyo Dib-u-shahaalinta
Saxanka dusha sare ee granite-ka ma aha maalgashi "deji oo iska illow". Xitaa saxannada ugu fiican waxay u baahan yihiin dib-u-xaqiijin xilliyeed si loo hubiyo inaysan ka bixin dulqaadka. ASME B89.3.7 waxay daboolaysaa shahaado cusub, dib-u-shahaadeyn goobta, iyo dib-u-shahaadeyn ka dib dib-u-sameynta. DIN 876 iyo JIS B 7513 waxay leeyihiin qodobbo la mid ah.
Dayactirka joogtada ah - nadiifinta dareeraha ku habboon, ilaalinta dusha sare ee saameynta, iyo isticmaalka daboollada saxda ah marka aan la isticmaalin - waxay si weyn u dheereysaa cimriga adeegga saxanka dusha sare. Marka saxanka ugu dambeyntii uu ka baxo dulqaadkiisa la cayimay, dib-u-hagaajinta farsamayaqaan aqoon u leh ayaa dib ugu soo celin karta xaalad la mid ah tii hore.
ZHHIMG®, kuma soo saarno oo keliya taarikada dusha sare. Waxaan bixinnaa taageerada wareegga nolosha oo dhan - laga bilaabo qeexitaanka bilowga ah iyo hagaajinta iyada oo loo marayo dib-u-shahaalin iyo dib-u-samaynta - sababtoo ah waxaan fahamsanahay in taarikada dusha sare aysan ahayn qalab oo keliya. Waa aasaaska nidaamkaaga cabbirka oo dhan.
