Pankhani ya zinthu zosagwirizana ndi zinthu, corundum, monga chinthu chofunikira kwambiri, yakhala chinthu chogwiritsidwa ntchito kwambiri mumakampani osagwirizana ndi zinthu chifukwa cha mphamvu zake zabwino zakuthupi ndi zamankhwala. Nkhaniyi ifotokoza za makhalidwe oyambira, ntchito zambiri, momwe msika ulili, komanso njira yopangira corundum mwatsatanetsatane, ndikuyang'ana kwambiri makina opukutira a corundum a 200-mesh kuti akuwonetseni momwe amatsogolera nthawi yatsopano yopukutira bwino.

Corundum ndi mwala wamtengo wapatali wopangidwa ndi kupangika kwa aluminiyamu. Kulimba kwake ndi kwachiwiri pambuyo pa diamondi ndi cubic boron nitride, ndipo kulimba kwake kwa Mohs kumafika 9. Dzina la corundum linachokera ku India. Gawo lake lalikulu ndi Al₂O₃, ndipo pali mitundu itatu: α-Al₂O₃、β-Al₂O₃、γ-Al₂O₃. Chifukwa cha mawonekedwe ake abwino kwambiri, corundum imagwiritsidwa ntchito kwambiri popanga zinthu zapamwamba zopukutira, mawotchi, zida zonyamulira makina olondola, ndi zina.

Kugwiritsa ntchito corundum

Mitundu yosiyanasiyana ya corundum imagwiritsidwa ntchito kwambiri, imagwira ntchito m'mafakitale ambiri monga zitsulo, makina, makampani opanga mankhwala, zamagetsi, ndege, ndi chitetezo cha dziko. Chifukwa cha kukana kutentha kwambiri, kukana dzimbiri, komanso mphamvu zake zambiri, corundum imagwiritsidwa ntchito ngati chophikira ndi chotengera chopangira zitseko zotsetsereka zachitsulo, kusungunula zitsulo zamtengo wapatali zosowa, ndi ma alloy apadera; m'makina, corundum imagwiritsidwa ntchito ngati zombo zosiyanasiyana zoyankhira ndi mapaipi ndi zida zamapompu a mankhwala; m'munda wamakina, corundum imagwiritsidwa ntchito popanga mipeni, nkhungu, zida zoteteza zipolopolo, ndi zina zotero. Kuphatikiza apo, zinthu zowonekera za corundum zingagwiritsidwenso ntchito kupanga nyali ndi ma microwave fairing, ndipo zinthu za Na-b-Al₂O₃ ndi zinthu zopangira ma electrolyte zopangira mabatire a sodium-sulfur.

Mkhalidwe wa Msika wa Corundum

M'zaka zaposachedwapa, chifukwa cha kupita patsogolo kwa sayansi ndi ukadaulo komanso kukula kwa mafakitale mwachangu, kufunikira kwa corundum kwapitirira kukula, ndipo chiyembekezo cha msika chili chachikulu. China, India, ndi Brazil ndi omwe amapanga corundum kwambiri padziko lonse lapansi, pakati pawo China ndiye wopanga komanso wogulitsa corundum yoyera kwambiri padziko lonse lapansi. Msika wa corundum umapereka mgwirizano woyambira pakati pa kupezeka ndi kufunikira, ndi khalidwe la malonda likupitilirabe kukwera ndipo madera ogwiritsira ntchito akupitilirabe kukula. Makamaka m'magawo apamwamba monga kupukuta ndi kupukuta molondola kwambiri, kugwiritsa ntchito corundum kukukulirakulira.

Njira yopangira corundum

Njira yopangira corundum imaphatikizapo magawo angapo monga kukonzekera zinthu, kusungunula, kuziziritsa, kupangitsa kuti zinthu ziume bwino komanso kukonzedwa. Choyamba, ufa wa aluminiyamu oxide woyeretsedwa bwino umafufutidwa ndikuumitsidwa kuti zitsimikizire kuti zinthu zopangirazo ndi zofanana komanso zoyera. Kenako, ufa wa aluminiyamu oxide umayikidwa mu ng'anjo yamagetsi ndikutenthedwa kutentha kwambiri kuti usungunuke kukhala madzi. Mu mkhalidwe wosungunuka, mamolekyu a aluminiyamu oxide amadzikonzanso kuti apange kapangidwe ka kristalo ndikupanga tinthu ta corundum. Kenako, kutentha kumachepetsedwa pang'onopang'ono kotero kuti tinthu ta corundum timalimba pang'onopang'ono kukhala cholimba. Pomaliza, chimatenthedwanso kuti kapangidwe ka kristalo kakhale kokhazikika komanso kowonjezera kuuma ndi kukana kutopa kwa corundum.

Chiyambi cha makina opukusira a 200 mesh corundum high efficiency

Pamene corundum ikugwiritsidwa ntchito m'magawo ena, imafunika kuphwanyidwa kaye mu ufa wosalala wa ma mesh 200, monga zopopera zitsulo, zinthu zagalasi zagalasi, ndi zinthu zowunikira za semiconductor. Gawo loyamba nthawi zambiri limakhala kuphwanyidwa. Pakadali pano, muyenera kugwiritsa ntchito makina opukutira a ma mesh 200 corundum. Guilin Hongcheng ndi kampani yayikulu yopangira zida zopukutira komanso zofufuzira. Mphero ya pendulum ya HC series yomwe adapanga ndi chisankho chabwino kwambiri pa makina opukutira a ma mesh 200 corundum.

Ma HC series swing mills amapezeka m'mitundu yosiyanasiyana, ndipo mphamvu zake zimasiyana kuyambira pa tani imodzi mpaka matani 50 pa ola limodzi. Zipangizozi zimakhala zokhazikika zikayamba, makina opanikizika opanda mphamvu amakhala ndi kutseka bwino, malo ogwirira ntchito ndi oyera komanso aukhondo, kukonza tsiku ndi tsiku ndikosavuta, ndipo mtengo wogwirira ntchito ndi wochepa. Amagwiritsidwa ntchito kwambiri mumakampani oletsa kugwedezeka ndipo amagwira ntchito bwino.

Makina opukusira a Guilin Hongcheng 200 mesh corundum omwe amagwira ntchito bwino kwambiri akukhala chida chofunikira kwambiri pakupanga mchere ndi kukonzekera zinthu chifukwa cha kugwira ntchito bwino, kusunga mphamvu komanso kuteteza chilengedwe. Monga chipangizo chopukusira chapamwamba, kufunikira kwa msika wa corundum kukupitilira kukula ndipo mwayi wamsika ndi waukulu. Takulandirani kuti mutitumizire uthenga kuti mupeze mtengo waposachedwa.
