ZVINHU ZVINOITA KUNHUTSA KWAKO KUNYANYA KUNYANYA KWESANDBLASTING

Abrasive media, mutengo wekushandisa wejecha midziyo, mutengo wevashandi, uye zvakabatanidzwa pamusoro - zvese mutengo. Nepo kuputika kweabrasive kunoshanda zvakanyanya kune dzakasiyana siyana dzekushandisa, zvakakoshawo kuti kunofanirawo kushanda zvakanaka. Kana zvasvika kune yakaoma abrasive blasting, kushanda kweseta yako yekuputika kunowanzoyerwa nehuwandu hwenzvimbo yaunokwanisa kuvhara munguva yakatarwa, uye huwandu hweabrasive yaunoshandisa kuzviita. Ichi chinyorwa chichavhara nzira dzakasiyana-siyana dzaungawedzera nadzo mukushanda kwejecha uye inotsanangura makiyi ekushandisa paramita kuti uwane iyo optimum hwindo rekuputika.Kutevera inotarisa pamatekiniki uye matipi ekuti ungashandise seize izvo zvishandiso, zvinosiyana, uye mamiriro ekuvandudza sandblasting kunyatsoita.

1. Kuputika pakudzvinyirirwa kwepamusoro kwakakodzera kune inodiwa yepamusoro chimiro

Zvose zvinotanga nemusanganiswa wemhepo uye abrasive.when zvinhu zviviri izvi zvinouya pamwe chete, mhepo yepamusoro-soro inopa abrasive ine kinetic simba. Uye iro rakawanda simba reabrasive yako, ndiko kuwedzera kwaichaita pamusoro peuri kuputika. Izvi zvinoreva kuti iwe unogona kupedza basa rako munguva shoma uye nekusanyanya kushungurudza. Saka, iwe unogona sei kupa yako abrasive iyo yakawedzera kick ye kinetic simba? Izvo zvese nezvehuwandu uye nekukurumidza kwegrit. Saizi uye huremu hweabrasive yako inotarisisa huremu hwayo, ukuwo inlet pressure pamhepo inoputika inogadzira kumhanya kwayo. Uye heino kicker - iyo yakakwira kudzvanywa pamuromo, nekukurumidza abrasive yako ichafamba.

Nekudaro, kudzvanywa kwaunoputika pairi kucharatidza kukurumidza uye kudzika kweiyo profil yauchawana. Saka, iwe unofanirwa kusarudza kudzvanywa kwakakodzera kune yako chaiyo application.

Kuti uwedzere kuputika kwako kushanda zvakanaka, unofanirwawo kudzivirira kurasikirwa kwesimba. Kurasikirwa uku kunoitika zvakanyanya mumushini weabrasive blast uye nekureba kwepoipi yekuputika. Friction ndicho chikonzero chikuru chekurasikirwa kwesimba mumushini wekuputika. Naizvozvo, zvakakosha kugadzira muchina unoputika une dhayamita yakakura yepombi uye zvirambidzo zvishoma sezvinobvira kuderedza kurasikirwa kwesimba. Pakupedzisira, mamiriro uye urefu hwekuputika kwako hose zvinokanganisawo kuwanda kwekumanikidzwa kurasikirwa. Itsva, yakaomesesa, kana yemhando yepamusoro yekuputika hose inobata chimiro chayo zvirinani, ichiva nechokwadi chekuti yakatwasuka, yakapfava nzira yemhepo uye kuyerera kweabrasive. Iyo yakareba hose yekuputika, ndiko kuwedzera kwekumanikidza kwaunorasikirwa nepakati. Nekugadzirisa imwe neimwe yemhando idzi, unogona kuvandudza zvakanyanya kushanda kwemaitiro ako ekuputika uye kuwana mhedzisiro inokatyamadza.

Izvo zvakakoshawo kufunga nezve opareta kunyaradza uye kuneta. Mushure mezvose, mushandisi anofara mushandisi ane zvibereko. Saka, iwe unogona kugara uchisarudza mutsara wakareruka-huremu kuita kuti maitiro awedzere kugadzikana.

2: Rova iyo Yakarurama Balance yeMhepo uye Abrasive media

Kukosha kwekuwana musanganiswa wakakodzera wemhepo uye abrasive haigone kuwedzeredzwa Imwe yezvikanganiso zvinowanzoitika izvo majecha anoita kuisa midhiya yakawandisa mumhepo stream. Isu tinozviwana, iwe unoda kuputika zvakanyanya sezvinobvira, asi midhiya yakawanda haireve kuwedzera kubereka. Inogona kudzikamisa mhepo yako uye kuderedza simba rekuita re media yako, pakupedzisira kukanganisa simba rako rose rekuputika. Izvi hazvingoite kuti kuputika kwako kuite kushoma asi zvakare zvinoreva kuti unozopedzisira wava kushandisa abrasive kupfuura zvakafanira, zvichitungamira kune kumwe kuchenesa uye kuwedzera mari yeprojekiti.

Kunyanya kushomeka mumhepo kunoreva kuti unozopedzisira wapedza nguva yakawanda uchiputika nzvimbo imwe chete, iko kutambisa nguva uye zviwanikwa.

Ndicho chikonzero kuwana chiyero chakanaka chakakosha. Nekurongeka kwakaringana kweabrasive media valve yako, unogona kuchengetedza nozzle pressure uye abrasive kumhanya uchiri neabrasive yakakwana kuputika pamusoro zvakanaka.

Hakuna pasiresesally yakanaka kugadzika sevagadziri vakasiyana vane magadzirirwo akasiyana eabrasive mavharuvhu uye midhiya inoyerera inoenderanawo nekudzvanywa kwemhepo uye rudzi rwemidhiya inoshandiswa. Kuti ugadzirise zvakanaka midhiya inopinda mumhepo yako, tanga ne zero kuyerera uye ita kuti mushandisi akonzerese sandblast poto. Zvishoma nezvishoma vhura vharafu yemedia kusvika mhepo yemhepo yave yakadzima zvishoma kubva pamhepo inoputika. Unofanira kutonzwa muridzo unogutsa paunovhara vharuvhu. Sezvo iwe uchivhura zvishoma nezvishoma vheji yemedia, teerera kune ruzha uye gadzirisa zvinoenderana kana shandisa bvunzo yekuona - chero iri nyore kwauri. Nekutsvaga iyo yakakwana midhiya-kune-mhepo chiyero, unogona kuwedzera kuputika kwako kunyatsoita uye kuwana mhedzisiro yepamusoro.

3.Tarisa saizi Yendege uye saizi yeNozzle

Kuti uwane kubereka kwakanyanya, iwe unofanirwa kuve nechokwadi chekuti uri kudyisa poto yako yejecha nendege inotakura vanhu yakakura zvakapetwa ka4 pane jecha rejecha rawasarudza. Kutadza kuita izvi kunogona kukonzera kudzikira kwakanyanya muCFM uye kudzvanywa, zvichiita kuti hari yako inoputika isashande zvakanaka uye kuita kuti isashande zvakanaka.

Usarege mutsara wekutengesa uchidzikamisa kuita kwako sandblasting. Nendege hombe yekudyara, iwe unokwanisa kuwana yakakwira CFM uye kudzvanywa, zvichikonzera nzira inoshanda yekuputika.

4. Tarisa Blast Hose yako yekudzora

Kazhinji, abrasive media particles anogadzira mhirizhonga mumhepo inoyerera mumhepo inoputika asi izvo zvinogona uye zvinofanirwa kudzorwa, ndiyo isingakoshi mhirizhonga mhedzisiro inogadzirwa nekuchinja kune chimiro uye kona yekuputika hose. Kune yega yega bend, constriction, uye/kana kurasikirwa kwekusimba mubhomba hose, kudzvanywa kwakasiyana kunogadzirwa.It zvakakodzera kuyeuka izvozvo kudzvinyirirwa kusiyanisa kunokonzera kurasikirwa kwesimba uye pakupedzisira kuderedzwa kwekumanikidzwa pamuromo. Chirevo chiri nyore uye chisingadhuri kuti udzivise kurasikirwa kusingakoshi kwekumanikidza ndeyekutarisa kana yako yekare blast hose yakarasa kusimba kwayo uye kana yave yakaradzikwa zvisizvo nemabhendi akasimba uye ichimhanya pamusoro pemicheto yakapinza.

5. Angle of Attack

Kana kuputika kwejecha, kona iyo iyo abrasive media inofambiswa pamusoro inotariswa nenzvimbo yemuromo inobatwa nemushandisi. Kona yekurwisa ikona iyo muromo unonongedzwa kubasa chidimbu. Kunyanya kucheneswa kwemhepo kunoputika kunoitwa nemuromo wakabatwa pakati pe60º kusvika 120º kumusoro. Manozzles akabatwa perpendicular (90º) kusvika pamusoro anopa simba rakananga iro rinogona kubatsira kutsemuka kwakasimba mabhanhire Zvisinei, kana iwe ukaputika zvakanangana nepamusoro pe substrate, midhiya kubva kumhepo inoputika inodhumhana nezvimedu zvinoputika kubva pamusoro uye. zvichaderedza kukanganisa. Kudzikamisa kuputika midhiya kudhumhana uye kuwedzera kubereka, pachinzvimbo chekunongedza muromo wakanangana nepamusoro, unofanirwa kufunga nezve kuputika kwejecha pakona diki kunzvimbo inoputika. Vane ruzivo abrasive blast operators vanoshandisa musanganiswa kuti vawane kubudirira kwepamusoro.

6. Standoff Distance

Chinhambwe (standoff distance) kureva chinhambwe chinobatirwa muromo maererano nechinhu chiri kuputiswa. Chinhambwe ichi chakakosha mukupusha kuputika kweabrasive. Blast vanoshanda vanofanirwa kukwirisa chinhambwe kuti uwane yaunoda kuputika pateni uye chiyero chekuchenesa. Chinhambwe ichi chinogona kubva pa18cm kusvika pa60cm. Kazhinji, mipumburu inobatwa padhuze ne substrate kuchenesa zvakasimba adherent mill scale kana coatings zvinoda diki blast pattern kuti iwane kucheneswa kwepamusoro. Kana nzvimbo dziri kucheneswa dzichiratidza mabhachi anobatirira kana kuti chigayo chinoputika uye ngura, hombe yekuputika inogadzirwa panzvimbo dzakakura dzekumira inobvumira kuchenesa nekukurumidza.

7. GaraNguva

Gara nguvae ndiyo nguva yenguva inodiwa kuti uwane iyo inodiwa kuchena kwepasi pamberi pemuromo wagona kutamiswa kuenda kune inotevera nzvimbo pane substrate. Inoreva huwandu hwenguva inodiwa kuti uwane nhanho inodiwa yehutsanana mumuromo usati waendeswa kunzvimbo inotevera. Thestay nguva inokanganiswa zvakanyanya nehukuru hweiyo blast pattern. Kune madiki mapatani, iyo muromo inobatwa padhuze nepamusoro, zvichiita kuti pave nenguva pfupi yekugara. Sezvineiwo, kuputika kukuru kunoda nguva yakareba stay nguva. Zvakadaro, hunyanzvi hwemushandisi uye kuenzanisa izvo chaizvo zvehutsanana zvinodiwa zvinotsanangurwa zvinogona kubatsira kudzikisirastay nguva, izvo zvinozoita kuti kuwedzere kubereka.
