The Abrasive Blasting

Brief Nhanganyaya

Abrasive bchisingaperi inzira yesurface finishingne propellingmediapaa kumhanya kwepamusoro kwariri. Inokurumidza uyesimplenzira yekubvisazvinosvibisa pamusorokubva simbi, rabha,kana plastiki.

Abrasive blasting inowanzoitwa munzvimbo dzakavharwa dzakadaimakamuri anoputika kana makabati, kana panzvimbo dzakavhurika senge muchikepe, chivakwa, uye bhiriji, nezvimwe.

The Types

Binogara ine akawanda akajairwa marudzi zvinoenderana neakasiyana midhiya:

 Sandblasting

 Wet abrasive blasting

 Vapor blasting

 Bead blasting

 Dry-ice blasting

Blasting ine matatu midhiya ekutumira masisitimu:

 Kuputika kwemhepo (pneumatic)

 Mechanical vhiri (airless blasting)

 Hydro blasting (inopomba mvura)

Sandblasting

Sumo Pfupi

Sezvo atype yeabrasive blasting, sandblasting inzira yekurapa pamusoro iyo inowanzo ine air compressor, abrasive particles, uye nozzle yekupfapfaidza abrasive particles pasi pekuyerera kwemhepo mukumanikidza kwakanyanya. Inonzi sandblasting nekuti inoputika nezvidimbu zvejecha. Kana zvimedu zvejecha zvapfapfaidzwa pamusoro, zvinogadzira inodiwa.

Nhoroondo yejecha uye nozzles

Sandblasting chiitikozvinoitika muzvakasikwa, kwete kugadzirwa kwevanhu. Naizvozvo, kana tichidazivaapo sandblasting yakaonekwa, inogona kuteverwa kumashure kwekutanga kwekuberekwazvepanyika. Guruva, jecha,kana chidimbukuputikanemhepo ine simba rekushandukopamusoro pechimwe chinhu pakubata. Tora muenzaniso muhupenyu hwedu, kukukurwa kwemhepo.

Muna 1980, mumwe murume anonzi BenjaminChew Tilghmanakawana ichi chiitiko chemusikirwo paakaona mahwindo aive nejecha raipeperetswa nemhepo paari. Uyezve, akagadzira muchina unogona kufambisa zvidimbu zvejecha nemhepo yakamanikidzwa kuenda pamusoro pezvinhu. Ndiyo yekutanga jecha muchina unonzi straight bore nozzle.

Nyanzvi yemasvomhu yekuSwitzerland uye nyanzvi yefizikisi Daniel Bernoulli akawana kuti tiye air pressure musiyano inogona kuwedzera kumhanya kweabrasive kuyerera, iyo inozivikanwa saBernoulli’s Principle.

Zvino muna 1700s, musimboti uyu wakawedzerwa neItaly Physicist Giovanni Battista Venturi. Kusvikira kuma1950, Venturini nozzles yakaonekwa kunyangwe iyo Venturi mhedzisiro yaivepo kare kare.

Kwemakore akawanda, marudzi akasiyana-siyanaemhuno dzakagadzirwa zvinoenderana nezvinodiwas. Formuenzaniso,venturi nozzle ndiyo yakanakisa sarudzo yekushanda sandblasting.

Venturi Nozzle: Venturi nozzles inoratidzira yakafara kuputika pateni inosimudzira kuputika zvakanyanya. Iyo Nheyo ndeyokuti kuderedzwa kwekumanikidzwa kwemvura kunounza kuwedzera kwemvura’s velocity.

Mvura Induction Nozzle: Iyo inoratidzwa neiyo fluid inosanganisa abrasive particles uye mvura yekurapa kwepamusoro. Kuenzaniswa nemamwe ma nozzles, ine hushamwari kune hutano hwekudzvinyirira guruva.
