Okhakhala ufa: kupanga ndi mowa. Kodi ndingatani ntchito ufa abrasive?

abrasive ufa - kwambiri kufunika m'nkhaniyo makampani ntchito yoyeretsa zitsulo ndi dzimbiri. Pali zingapo mitundu yake, amene amasiyana katundu ndi ndalama. Okhakhala ufa ntchito mankhwala pamwamba angakhalenso m'njira zosiyanasiyana.

wachuma

Panopa, makampani umabala awiri okha mitundu ikuluikulu ya ufa abrasive: kupershlak ndi nikelshlak. Ntchito kupanga, iwo anayamba osati kale. Poyamba ntchito m'malo wamba khwatsi mchenga. Pamene kukonza padziko yotsirizira mu mlengalenga kufalitsa fumbi zabwino kwambiri, kuchotsako zonse. Pa nthawi yomweyo ine ndinali kupanga m'malo nthawi yambiri ndi ntchito yokwera mtengo wa kusamba mankhwala ankachitira. Komanso, particles chabwino wa khwatsi, zouluka mlengalenga akulowa mapapo ntchito. Motero, iwo anayamba aakulu matenda kuntchito - silicosis. Mwatsoka, mu dziko lathu mtengo khwatsi mchenga kwa kali kuyeretsa ntchito kutali. Ku Ulaya, ntchito Mwaichi ndi koletsedwa.

mitundu

Nthawi zambiri ntchito m'mafakitale kupershlak. Izi ndi zinthu zotsika mtengo, kulola kuyeretsa mosabvuta. Nikelshlak isiyana izo wamkulu tinthu mphamvu. Nthawi zina ntchito mu makampani mtundu uwu abrasives, diamondi ufa. Komabe, ndalama mtengo kwambiri, choncho ntchito makamaka kwa zotsimikizira zida akupera, pastes ndi slurries.

Kodi wapangidwa

Zotsimikizira ufa abrasive - ndondomeko si makamaka zovuta mwaukadaulo. Kupershlak wa granulated slag yadothi. malipiro awo mu mkhalidwe wabwino ndi kuzirala mofulumira ndi madzi. The ufa chifukwa cha kuyeretsedwa zosiyanasiyana zosafunika osafunika kuika pa wapadera okonda kabati ndi maselo ang'onoang'ono. Chifukwa, particles ang'onoang'ono kupershlak anadzuka pansi. Large monga (miyala, zipangizo refractory, zinyalala) kukhala pamwamba.

Nikelshlak anapanga pa njira yomweyo. Kusiyana kokha kuti mu nkhani iyi feedstock ntchito faifi tambala slags.

makhalidwe a

The katundu waukulu kudziwa khalidwe la zinthu monga ufa abrasive, ndi:

1. Mlingo wa hygroscopicity. Zing'onozing'ono ndi bwino mankhwala. ufa youma angagwiritsidwe ntchito ndondomeko kupanga yomweyo, popanda kuthera nthawi ndi ndalama kuti ziume.

2. Flowability. chiwerengerochi chili ufa abrasive ayenera kukhala mkulu monga zotheka. Kwambiri zipangizo lotayirira mosavuta kudzera zida nozzle anafuna kukonza pamalo popanda clogging iwo. Chifukwa, wautali zida samalephera.

3. Pali wa ting'onoting'ono. Quality amaona kuti nkhani yokha yomwe imakhala ndi particles zamitundu yosiyanasiyana (kuchokera 0,5 3 mm).

Malinga ndi digiri ya ngozi kwa thupi abrasive ufa anatumizidwa ku gulu chachinayi. Izi zikutanthauza kuti mukhoza ntchito nawo popanda kuopa mavuto thanzi lawo. Yerekezerani: kuwonjezera wachinayi kalasi ya ngozi wachinsinsi zipangizo monga zitsulo zotha ndi ufa otsala mu umapezeka mbali zitsulo.

Mbali

Choncho, ufa kwambiri abrasive ntchito kukonza pamalo katundu zitsulo ku rusting. Komanso, ntchito kuchotsa utoto ndi pulasitala zatsalira kwa konkire ndi njerwa. Ntchito ufa abrasive akhoza kuonongedwa kapena kuchotsa mbali thawed ponyamula kunja kukonza.

Ikuchitika padziko chithandizo cha nkhaniyi mungathe ngati njira ochiritsira abrasive, ndi madzimadzi lawi kumva kuwawa.

Kuyerekezera kupershlak ndi khwatsi mchenga

Kumene, masiku ano abrasive ufa ndi odula koposa mchenga khwatsi. Komabe, ntchitoyo abwino kwambiri. Chifukwa ndi losavuta kumva, pansipa ife azipereka kwa tcheru chanu fanizo tchati zipangizo awiri.

Okhakhala mowa ufa

M'gulu kupershlak ndi particles nikelshlaka ndi m'mbali lakuthwa kwambiri. Choncho, pamwamba mankhwala angathe kuchitidwa bwino kwambiri. Choncho, mosiyana ndi mchenga khwatsi, abrasive ufa pafupifupi musati kupanga fumbi. Choncho, kukonzedwa mankhwala safuna kusamba, kuthera ndalama zina.

Fumbi pa oyera khwatsi mchenga aumbike chifukwa particles ake zambiri wosweka. Ndi ufa abrasive kuti pafupifupi zimachokeradi. Choncho iwo angagwiritsidwe ntchito kawiri pa kuyeretsedwa, ndipo nthawizina katatu. Ndithudi, izi kwambiri kumachepetsa mowa awo. Motero, sangalalani kupershlak nikelshlakom ndi opindulitsa, ngakhale kuti iwo ali kwambiri mtengo kuposa mchenga. Kumwa ufa abrasive pa 1 m2 ndi pafupifupi 30 kg. Yerekezerani mchenga m'dera lomweli uyenera kutaya 100 makilogalamu.

Okhakhala ufa: Standard

Mlingo wa chikoka pa thupi la munthu ndi kupershlak nikelshlak, monga tanenera kale, za chachinayi gulu (GOST 12.1.007). Mu kupanga ufa malamulo abrasive ziyenela kuyan'anidwa ndi kulemekeza GOST 17.2.3.01-86 malire umuna. Amasintha State Standard ndi mtundu wa zodzitetezera pamene ntchito ndi ogwira ntchito kupershlak nikelshlakom (GOST 12.4.034). The pazipita kololeka zili radionuclides zachirengedwe ufa abrasive malamulo GOST 30108. Kwenikweni nkhaniyi nthawi zonse umachitikira pansi Lachiwiri 1789-001-34557754-99.

Ntchito kunyumba

Ena ojambula ndi chidwi, pamene inu mukhoza kugwiritsa ntchito ufa abrasive. Kupershlak ndi nikelshlak kunyumba sizingakhale zothandiza. Iwo ntchito mwachindunji lalikulu zedi kukonza yaikulu m'dera pamalo. ntchito diamondi makamaka yekha ufa kunyumba. Iwo bwino yosayenera yopanga pastes, anafuna kupukuta mitundu yosiyanasiyana ya mankhwala zitsulo za mawonekedwe zovuta.

Komanso diamondi ufa zambiri ntchito popanga kudziletsa akukuta chida. Pankhaniyi, monga maziko a mwala amagwiritsidwa ntchito yapadera abrasive. Pambuyo degreasing amanena wosanjikiza ntchito ya kapangidwe zotsatirazi (% ndi kulemera):

• diamondi ufa - 2-4;

• okusayidi mkuwa ufa - 25-35;

• asidi phosphoric - yotsala.

mtengo wa

Price nikelshlak ndi kupershlak za chomwecho. ufa amenewa ndi dongosolo la rubles 3000-3500 pa tani. Mtengo wa mchenga khwatsi ndi mu osiyanasiyana rubles 800-900 pa tani. Diamondi ufa, ayenera, okwera mtengo kwambiri. Gulitsani si matani kapena ngakhale makilogalamu ndi magalamu. ndalama 35-70 rubles pa gram.

Monga mukuonera, abrasive ufa - nkhaniyo chotchuka kwambiri ndi zothandiza. mitundu yake yosiyanasiyana akhoza kugwiritsidwa ntchito mu mafakitale ndi kunyumba. Vuto ayi, makhalidwe ntchito ya osiyana zodabwitsa basi.
