Xiriirka ka dhexeeya Mesh iyo Microns
Shaqaalaha warshadaha budada waxay inta badan isticmaalaan ereyga "xajmiga mesh" si ay u qeexaan cabbirka walxaha. Haddaba, waa maxay cabbirka mesh-ka iyo sidee ayay ula xidhiidhaa microns?
Cabbirka mesh waxa loola jeedaa tirada godadka shaandho, taas oo ah tirada godadka halkii inji oo labajibbaaran. Mar kasta oo cabbirka meshku uu sarreeyo, waa ka sii yaraanaya cabbirka daloolka. Guud ahaan, cabbirka mesh lagu dhufto cabbirka daloolka (micron) Iyadoo ay ugu wacan tahay arrinta bannaanka bannaan, taas oo ay ugu wacan tahay kala duwanaanshaha dhumucda siliga loo isticmaalo marka shabkada la toleynayo, dalal kala duwan ayaa leh heerar kala duwan. Hadda waxa jira saddex heer: Maraykan, Ingiriis, iyo Jabbaan, iyadoo halbeegyada Ingiriiska iyo Maraykanku ay isku mid yihiin iyo halbeegga Jabbaan uu ka duwan yahay. Halbeegga Mareykanka ayaa guud ahaan la adeegsadaa, qaacidada sare lagu sheegayna waxaa loo isticmaali karaa xisaabinta.
Waxaa la arki karaa in cabbirka meshku uu go'aamiyo cabbirka daloolka shaandhada, iyo cabbirka daloolka shaandhada ayaa go'aaminaya cabbirka qaybta ugu badan ee Dmax ee budada dhexmarta shaandhada. Sidaa darteed, ma habboona in la isticmaalo cabbirka mesh si loo go'aamiyo xajmiga qaybta budada. Habka saxda ah waa in la isticmaalo cabbirka walxaha (D10, dhexroor dhexdhexaad ah D50, D90) si loo matalo cabbirka walxaha iyo in la isticmaalo ereybixin caadi ah si looga fogaado farqi kasta. Waxa kale oo muhiim ah in si joogto ah loo cabbiro qalabka iyo qalabka iyadoo la isticmaalayo budada caadiga ah.
Heerarka qaranka ee la xidhiidha budada:
- GBT 29526-2013: Eraybixinta Tiknoolajiyada Budada
- GBT 29527-2013: Calaamadaha Garaafka ee Qalabka Habaynta Budada
- GB/T 6003.1-2022: Heerka qaranka ee qeexaya cabbirrada daloolka ee shaandhada tijaabada ah isla markaana u adeega sidii tixraac rasmi ah oo loogu talagalay beddelka cabbirka walxaha iyo tirada shabagga warshadaha.
Waxaan u maleynayaa in tani ay tahay mid ka mid ah macluumaadka ugu muhiimsan aniga. Waana ku faraxsanahay akhrinta maqaalkaaga. Laakiin waa in aad wax ka sheegtaa qaar ka mid ah waxyaabaha guud, Habka goobta waa cajiib, maqaaladu runtii aad bay u fiican yihiin: D. Shaqo wanaagsan, farxad
Waxaan si joogto ah uga raadinayaa internetka qoraallada i caawin doona. Wax badan ayaa cad in arrintan laga barto. hambalyo!
