Isifinyezo Seshadi Losayizi Wemeshi Yesikrini Esidlidlizayo
Ishadi likasayizi wesikrini semeshi elidlidlizayo liyithuluzi elibalulekile lokukhetha isikrini esilungile sezinhlelo zokusebenza ezihlukene zokuhlukanisa izinto. Kukusiza ukuthi uqonde ubudlelwano phakathi “kwenombolo yemeshi” (noma isibalo se-mesh) kanye “nembobo” yangempela noma usayizi wokuvula wesikrini.
Ishadi Losayizi Wemeshi Yesikrini Edlidlizayo
Ukuqonda Usayizi We-Mesh:
Inombolo Ye-Mesh (noma Ukubala Kwe-Mesh): Lokhu kubhekisela enanini lokuvuleka ngeyintshi ngayinye yesikrini.
Inombolo yemeshi ephakeme = Izivulo ezincane = Izinhlayiya ezincane
Inombolo yemeshi ephansi = Izivulo ezinkulu = Izinhlayiya ezimaholoholo
Usayizi Wembobo: Lona ubukhulu bomzimba bangempela bokuvuleka phakathi kwezintambo ezisemeshi. Ngokuvamile kuvezwa ngamamilimitha (mm), ama-micrometer (µm noma ama-microns), noma amayintshi.
I-Wire Diameter: Ubukhulu bocingo olusetshenziswa ukuluka inetha. Lokhu kuthinta iphesenti lendawo evulekile.
Iphesenti Lendawo Evulekile: Lesi isilinganiso sendawo evulekile (imbobo) nendawo ephelele yemeshi. Indawo evulekile ephakeme ngokuvamile isho ukugeleza okungcono kanye nokuphumayo.
Amazinga Abalulekile:
Yize lingekho izinga elilodwa elijwayelekile, ezijwayelekile zifaka:
Usayizi weSieve wase-US (ASTM E11): Lokhu kwamukelwa kabanzi, ikakhulukazi emazweni afana ne-China ngezikrini ezidlidlizayo ezithunyelwa ngaphandle.
I-Tyler Standard: Enye indinganiso evamile, ngezinye izikhathi esetshenziswa ngokushintshana ne-US Mesh yegrit abrasive.
Amazinga e-ISO: Izindinganiso zamazwe ngamazwe zikhona.
Isibonelo Seshadi Losayizi Wemeshi Ojwayelekile (Enziwe Lula):

Indlela Yokufunda Nokuhumusha:
Thola usayizi wezinhlayiyana owufunayo: Uma udinga ukuhlukanisa izinhlayiya ezincane kunosayizi othile (isb., 2 mm), thola lowo sayizi wokuvula eshadini.
Khomba inombolo yemeshi ehambisanayo: Ishadi lizokubonisa inombolo yemeshi edala lokho kuvuleka. Esibonelweni esingenhla, u-2 mm uhambisana nesikrini se-mesh engu-10.
Cabangela i-diameter yocingo: Nakuba kungahlali kufakwe ngokucacile ohlwini lweshadi elenziwe lula, khumbula ukuthi i-diameter yocingo ithinta indawo evulekile. Izintambo eziwugqinsi zenombolo yemeshi efanayo zizophumela endaweni encane evulekile.
Ama-Microns vs. Mesh: Ukuze kuhlolwe kahle kakhulu (imvamisa engaphansi kuka-325 mesh), usayizi we-micron uvame ukusetshenziswa ngokuqondile njengoba inombolo ye-mesh iyancipha ukusebenza.
Izinto Ezithonya Ukukhethwa Kwemeshi (Ngaphandle Kosayizi Nje):
Ngale kosayizi we-mesh uqobo, ezinye izinto ezimbalwa zibalulekile lapho ukhetha isikrini esidlidlizayo:
Izici zezinto ezibonakalayo:
Ukusabalalisa Usayizi Wezinhlayiya: Ibalulekile ekunqumeni indawo yokusika.
Uhlobo Lwempahla: Izinto ezigugulekayo (igwadle) zidinga inetha eliqinile (insimbi eqinile), izinto ezinamathelayo/ezinobumba zingase zidinge i-polyurethane noma irabha ukuvimbela ukuvala, nezinto ezingasindi (amashidi okhuni) zingasebenzisa izimbobo ezinkulu.
Okuqukethwe Umswakama: Izinto ezimanzi noma ezinamathelayo zingadinga izikhala zokuzihlanza noma izimbobo ezimaholoholo ukuze kuvinjelwe ukungaboni.
Umumo Wezinhlayiya: Izinto ezithambile noma ezinde zingadinga anezikhala ezibolekile esikhundleni sesikwele.
Ukuhlola Ukusebenza Nempumelelo:
Izimbobo ezinkulu zinikeza umthamo ophezulu kodwa ukunemba okuphansi.
Izimbobo ezincane zinikeza ukunemba okungcono kodwa okuncishisiwe kokuphuma.
Iphesenti Lendawo Evulekile: Indawo evulekile ephakeme ngokuvamile isho ukugeleza okungcono, ikakhulukazi ezintweni ezimahhadla.
I-Mesh Material:
I-Carbon Steel: Inhloso evamile, izindleko eziphansi.
Insimbi Engagqwali: Okwezindawo ezonakalisayo noma ezimanzi.
I-Polyurethane: Ilungele izinto ezinamathelayo, ukumelana nokugqokwa okuhle, nokunciphisa umsindo.
Irabha: Ngomthelela osindayo kanye nokumelana nemihuzuko, ibuye inciphise umsindo.
Ipuleti Elinezimbobo: Ngendawo evulekile ephezulu namandla ku-heavy-duty scalping.
Uhlobo Lwesikrini Esidlidlizayo Nomklamo: Izikrini ezigodliwe, izikrini ezivundlile, imvamisa yokudlidliza, nama-amplitude konke kudlala indima endleleni i-mesh ethile esebenza ngayo.
Inombolo Yamadekhi: Izikrini zedekhi eminingi zivumela ukwahlukaniswa okuhlukahlukene kumasayizi ahlukene anezikhala.
Lapho Ungathola Khona Amashadi Aqondile:
Iningi labakhiqizi bezikrini ezidlidlizayo (isb., Haiside, McLanahan, Metso, Sanyuantang, Boedon, Cleveland Vibrator) bahlinzeka ngamashadi abo osayizi wemeshi anemininingwane nemihlahlandlela yokukhetha ezincwadini zabo zomkhiqizo noma kumawebhusayithi abo. Kuhlala kuhle kakhulu ukuthi uthintane nezincomo zomkhiqizi ngohlelo lwakho lokusebenza oluthile.
