Kodi mukudziwa sandblasting? –Chidule chachidule cha sandblasting 

Kuphulika kwa mchenga komwe kumadziwikanso kuti kuphulika kwa abrasive, ndi njira yoyendetsa tinthu tating'onoting'ono ta chinthu chonyezimira pa liwiro lalitali kupita kumtunda kuti chiyeretse kapena kuzimitsa. Ndi ntchito yomaliza ya pamwamba yomwe imaphatikizapo kugwiritsa ntchito makina oyendera mphamvu (air compressor) komanso makina opukutira mchenga kupopera tinthu ting'onoting'ono tomwe timatulutsa timadzi tomwe timayambukira pamwamba. Amatchedwa "sandblasting" chifukwa amawombera pamwamba ndi tinthu tating'ono ta mchenga. Mchengawo ukagunda pamwamba, umapangitsa kuti pakhale mawonekedwe osalala komanso owoneka bwino.

Kugwiritsa ntchito Sandblasting

Kupukuta mchenga ndi imodzi mwa njira zabwino kwambiri zoyeretsera ndi kukonza malo. Omanga matabwa, okonza makina, okonza magalimoto, ndi enanso onse angagwiritse ntchito kuphulitsa mchenga m’ntchito yawo, makamaka pamene amvetsetsa bwino lomwe njira zambiri zophulitsira mchenga.

1. Chotsani Dzimbiri ndi Zimbiri:Chomwe chimagwiritsidwa ntchito kwambiri pama media ndi mchenga ndikuchotsa dzimbiri ndi dzimbiri. Ma sandblasters amatha kugwiritsidwa ntchito kuchotsa utoto, dzimbiri, ndi zinthu zina zowononga pamtunda m'galimoto, nyumba, makina, ndi pafupifupi malo ena aliwonse.

2. PamwambaKuchiza:Kuphulika kwa mchenga ndi kuphulika kwa ma TV ndi njira yabwino yokonzekeretsera pamwamba kuti apange utoto kapena zokutira. M'dziko lamagalimoto ndi njira yomwe imakonda kuwulutsa chassis m'mbuyomukupaka ufaizo. Makanema ankhanza kwambiri ngati aluminiyamu okusayidi amasiya mbiri pamwamba yomwe imathandizira kuti malaya a ufa amamatire bwino. Ichi ndichifukwa chake opaka ufa ambiri amakonda zinthu kuti ziwombedwe ndi TV zisanakutidwe.

3. Kukonzanso kwa zigawo zakale:kukonzanso ndi kuyeretsa mbali zonse zosuntha monga magalimoto, njinga zamoto, zida za electromechanical, ndi zina zotero, ogwira nawo ntchito amachotsa kupsinjika kwa kutopa ndikuwonjezera moyo wautumiki.

4. Pangani Custom Textures ndi Zojambulajambula: Pazida zina zapadera, kuphulika kwa mchenga kumatha kukhala ndi mawonekedwe osiyanasiyana kapena matt. Monga kupukuta kwa zidutswa zosapanga dzimbiri zitsulo ndi mapulasitiki, kupukuta kwa yade, matting pamwamba pa mipando yamatabwa, chitsanzo pamwamba pa galasi frosted, ndi texturing padziko nsalu, etc. 

5. Kutulutsa kosalala kosalala ndi m'mphepete:Nthawi zina kuwomba kwapawayilesi kumatha kusalala kapena kupukuta pang'ono pamalo omwe amakhala ovuta. Ngati muli ndi nsonga yakuthwa kapena yowoneka bwino, mutha kugwiritsa ntchito media blaster yokhala ndi magalasi ophwanyidwa kuti muwongolere pamwamba kapena kufewetsa chakuthwa.

Momwe Kuwombera Mchenga Kumachitikira

Kukhazikitsa sandblasting nthawi zambiri kumakhala ndi zigawo zitatu zazikulu:

·Sandblasting makina

·Abrasives

·Kuphulika nozzle

Sandblasting makina ntchito wothinikizidwa mpweya monga mphamvu kupanga mkulu-liwiro jet matabwa kupopera zipangizo (kuwombera kuphulika galasi mikanda, wakuda corundum, corundum woyera, aluminiyamu, quartz mchenga, emery, chitsulo mchenga, mkuwa ore, nyanja Mchenga) kupopera pamwamba. za ntchito kuti kukonzedwa pa liwiro lapamwamba, amene amasintha mawotchi katundu wa kunja kwa ntchito pamwamba. Chifukwa cha kukhudzidwa ndi kudulidwa kwa abrasive pamwamba pa ntchitoyo, pamwamba pa ntchitoyo imapeza ukhondo wina waukhondo ndi roughness yosiyana. The makina katundu pamwamba pa ntchito chidutswa bwino.

Ngakhale dzinali, mchenga sizinthu zokhazo zomwe zingagwiritsidwe ntchito popanga "mchenga". Ma abrasives osiyanasiyana angagwiritsidwe ntchito kutengera zomwe akugwiritsa ntchito. Izi abrasives zingaphatikizepo:

·Chitsulo chachitsulo

·Malasha slag

·Owuma ayezi

·Zipolopolo za Walnut ndi kokonati

·Magalasi ophwanyidwa

Zida zoyenera zotetezera ziyenera kugwiritsidwa ntchito panthawi yophulika mchenga. Ma abrasive particles amatha kukwiyitsa maso ndi khungu, ndipo ngati atakokedwa, angayambitse silicosis. Aliyense amene akuchita sandblasting nthawi zonse azivala zida zoyenera zotetezera.

Kuphatikiza apo, nozzle yophulika ndi chinthu chofunikira kwambiri. Pali makamaka mitundu iwiri ya nozzles kuphulika: molunjika anabowola ndintchito mtundu. Pakusankha kwa nozzle, mutha kulozera ku nkhani yathu ina ya"Masitepe anayi akukuuzani momwe mungasankhire ma nozzles abwino".
