Sida loo isticmaalo qiyaasta dhumucda rinjiga rinjiga VIDEO
Dhumucda lakabka rinjiga baabuurka waxaa si cad u qeexay soo saaraha. Sidaas awgeed, si loo ogaado in baabuurka dib loo rinjiyeeyay ama in qaybo jirka ah lagu dayactiray rinjiyeyn dambe, waa ku filan in la cabbiro dhumucda rinjiga (LPC). Tan waxaa lagu samayn karaa iyadoo la isticmaalayo qalab gaar ah - cabbir dhumucdiisuna.
Hawlgalka cabbirka dhumucdiisuna waxay ku salaysan tahay mabda'a magnetic induction (F-nooca) ama habka eddy hadda (N-nooca). Haddii jidhku ka samaysan yahay biraha magnetic, markaa nooca ugu horreeya ayaa la isticmaalaa; haddii jidhku ka samaysan yahay walxo isku dhafan oo kala duwan ama biraha aan birta ahayn, markaa habka hadda jira ayaa la isticmaalaa.
Way ku filan tahay in lagu dabaqo cabbirka dhumucda dusha sare ee jidhka baabuurka, iyo qiimaha dhumucda rinjiga ee microns (kun ee milimitir) ama mils (cabbirka Ingiriisiga dhererkiisu waa 1 mil = 1/1000 inch) ayaa noqon doona lagu soo bandhigo shaashadeeda. Microns waxaa loo isticmaalaa Ruushka.
Dhumucda rinjiga celcelis ahaan waxay u dhaxaysaa 60 ilaa 250 microns. Lakabka ugu qaro weyn ayaa lagu dabaqaa baabuurta qaaliga ah ee Jarmalka, sida Mercedes - 250 microns, taas oo sharxaysa iska caabbinta aadka u fog ee daxalka. Inkasta oo tani ay sidoo kale ka muuqato qiimaha.
Si aad u cabbirto dhumucda rinjiga si sax ah, marka hore waxaad u baahan tahay inaad shid qalabka oo aad hagaajiso; tan, dhaqe gaar ah oo rinji lagu dhejiyay ama foorno khafiif ah ayaa lagu dari karaa qalabka. Marka natiijada saxda ah ay ka soo muuqato shaashadda, waxaad bilaabi kartaa inaad hubiso dhumucda rinjiga. Si arrintan loo sameeyo, si fudud u riix dareemaha cabbirka dhumucda oo sug ilaa natiijada ka soo baxdo.
Qiyaasaha dhumucda ayaa badanaa la isticmaalaa marka la iibsanayo baabuurta la isticmaalay. Dhumucda lakabka rinjiga waa in laga fiiriyaa saqafka, si tartiib tartiib ah u socdaan jidhka baabuurka. Nooc kasta oo baabuur, waxaad ka heli kartaa miisaska muujinaya dhumucda rinjiga ee meelo kala duwan - dabool, saqafka, albaabada. Haddii farqiga u yahay 10 - 20 microns, markaa tani waa qiimo gebi ahaanba la aqbali karo. Xataa mashiinada hadda ka soo baxay khadka kulanka, qaladka 10 microns waa la oggol yahay. Haddii dhumucdiisu ay dhaafto qiimaha warshadda, markaas baabuurka waa la rinjiyeeyay waxaadna si badbaado leh u bilaabi kartaa inaad dalbato qiimo dhimis.
Waxaa haboon in la ogaado in akhrinta dhumucda dhumucdiisuna ay ka soo saarayaasha kala duwan laga yaabaa in aanay u dhigma midba midka kale by qiyaastii 5-7 microns, sidaas darteed qaladkan waa la dayaci karaa.
