Mitundu ya Abrasive Blasting

Masiku ano, kuphulika kwa abrasive kumagwiritsidwa ntchito kwambiri m'mafakitale ambiri. Monga kumanga zombo ndi kuyeretsa hull, kukonza magalimoto ndi kukonzanso, kutsirizitsa zitsulo, kuwotcherera, kukonzekera pamwamba, ndi zokutira pamwamba kapena kupaka ufa etc. Kuphulika kwa abrasive kumadziwika kuti ndi njira yomwe anthu amagwiritsa ntchito kuyeretsa kapena kukonza pamwamba. Kuphulika kwa abrasive kumatha kutchedwanso kuphulika kwa mchenga, kuphulika kwa grit, ndi kuphulika kwa TV. Momwe timafotokozera kuti ndi mitundu yanji ya kuphulitsa kutengera zomwe zimagwiritsa ntchito.

Mitundu ya Abrasive Blasting

1. Kuphulika kwa mchenga

Kuphulika kwa mchenga ndi imodzi mwa njira zomwe anthu amakonda kugwiritsa ntchito poyeretsa pamwamba. Zomwe zimapangidwira ndi mchenga wa silika. Tinthu ting'onoting'ono ta silika ndi lakuthwa, ndipo amatha kusalaza pamwamba ndi liwiro lalikulu. Choncho, nthawi zambiri anthu amasankha sandblasting pochotsa dzimbiri pazitsulo.

Choyipa chokhudza silika ndikuti amatha kuyambitsa silicosis yomwe ndi matenda oopsa a m'mapapo omwe amayamba chifukwa cha kupuma fumbi lomwe lili ndi silica. Taganizirani thanzi la blasters, sandblasting pang'onopang'ono wagwa ntchito.

2. Kunyowa Kuphulika

Kuphulika konyowa kumagwiritsa ntchito madzi ngati zotsekemera. Poyerekeza ndi kuphulika kwa mchenga, kuphulika konyowa ndi njira yabwino kwambiri yowononga chilengedwe. Imaphulika popanda kupanga fumbi zomwe zimapangitsanso kukhala mwayi waukulu pakuphulika konyowa. Kuphatikiza apo, kuwonjezera madzi ophulitsa kumapangitsa kuti ikhale yosalala komanso yomaliza.

3. Koloko Kuphulika

Kuphulika kwa soda kumagwiritsa ntchito sodium bicarbonate ngati njira yowononga. Poyerekeza ndi ma media ena abrasive, kuuma kwa sodium bicarbonate ndikotsika kwambiri kutanthauza kuti kumatha kugwiritsidwa ntchito kuyeretsa pamalo osawononga malo. Kugwiritsa ntchito soda kuphulika kumaphatikizapo kuchotsa utoto, kuchotsa graffiti, kubwezeretsa mbiri yakale, ndi kuchotsa chingamu, ndi zina zotero. Kuphatikiza apo, kuphulika kwa soda kumakhalanso kogwirizana ndi chilengedwe. Chokhacho ndikuti soda bicarbonate imatha kuwononga udzu ndi zomera zina.

4. Kuphulika kwa Vacuum

Kuphulika kwa vacuum kumatha kutchedwanso kuphulika kopanda fumbi chifukwa kumapanga fumbi lochepa kwambiri komanso kutayikira. Pamene akuphulitsa vacuum, abrasive particles ndi zipangizo zochokera gawo lapansi zimatengedwa ndi vacuum nthawi yomweyo. Chifukwa chake, kuphulika kwa vacuum kumatha kuchepetsa kwambiri kuwonongeka kwa chilengedwe kuchokera ku tinthu ta abrasive. Itha kutetezanso thanzi la wogwiritsa ntchito ku tinthu tating'ono tomwe timapuma.

5. Kuphulika kwazitsulo zachitsulo

Chitsulo chachitsulo chimakhalanso chofala kwambiri chophulika. Mosiyana ndi chitsulo chowombera, grit yachitsulo imapangidwa mwachisawawa, ndipo imakhala yakuthwa kwambiri. Chifukwa chake, kuphulika kwachitsulo nthawi zambiri kumagwiritsidwa ntchito pophulitsa malo olimba.

Kupatula kuphulitsa mchenga, kuphulitsa konyowa, kuphulitsa koloko, kuphulitsa vacuum, ndi kuphulitsa zitsulo zachitsulo, palinso mitundu yambiri yophulika monga malasha, zitsononkho za chimanga, ndi zina. Anthu amasankha media abrasive malinga ndi zomwe amafuna pamtengo, kuuma, komanso ngati akufuna kuwononga pamwamba. Pali zinthu zambiri zofunika kuziganizira posankha media abrasive.

Anthu amafunikiranso kusankha zida zopangira ma nozzles ndi ma nozzle liners kutengera zomwe amasankha. Ku BSTEC, ziribe kanthu kuti mumagwiritsa ntchito media iti, tili ndi mitundu yonse ya ma nozzles ndi zomangira. Silicon carbide, tungsten carbide, ndi boron carbide zonse zilipo. Ingotiuzeni zomwe mukufuna kapena media abrasive yomwe mukugwiritsa ntchito, tipeza mphuno yoyenera kwambiri kwa inu.
