Izinto Okufanele Zicatshangwe Lapho Ukhetha Usayizi We-Nozzle
Lapho ukhetha usayizi we-nozzle we-sandblasting, izici eziningana kufanele zicatshangelwe. Lezi zici zifaka Uhlobo Lwe-Abrasive kanye Nosayizi Wegrithi, usayizi nohlobo lwe-compressor yakho yomoya, ingcindezi oyifunayo kanye nesivinini somlomo, uhlobo lwendawo eqhunyiswayo, kanye nezidingo ezithile zohlelo lokusebenza. Ake sijule kulokho ngakunye kwalezi zici.
1. Sandblast Nozzle Usayizi
Uma kuxoxwa ngosayizi wombhobho, ngokuvamile ubhekisela kusayizi wobhobo lombhobho (Ø), omele indlela yangaphakathi noma ububanzi obungaphakathi kwembobo. Izindawo ezihlukene zidinga amazinga ahlukene okuhlukumeza ngesikhathi se-sandblasting. Indawo ethambile ingase idinge usayizi omncane wombhobho ukuze unciphise umonakalo, kuyilapho izindawo eziqinile zingase zidinge usayizi wombhobho omkhulu ukuze kuhlanzwe kahle noma kususwe okunamathelayo. Kubalulekile ukucabangela ubulukhuni kanye nokuba sengozini kwendawo eqhunyiswa lapho kukhethwa usayizi wombhobho.
2. Uhlobo Lwe-Abrasive kanye Nosayizi Wegrit
Ama-abrasive ahlukene angase adinge osayizi abathile bombhobho ukuze afinyelele ukusebenza kahle futhi avimbele ukuvala noma amaphethini okuqhuma angalingani. Njengomthetho ojwayelekile wesithupha, imbobo yomlomo kufanele okungenani ibe nosayizi ophindwe kathathu wegrit, iqinisekise ukugeleza kwe-abrasive okusebenzayo nokusebenza okuhle kokuqhumisa. Okulandelayo ubudlelwano phakathi kosayizi be-nozzle bore kanye nosayizi wegrit:
Usayizi weGrit | Ubuncane Be-Nozzle Bore Usayizi |
16 | 1/4″ noma ngaphezulu |
20 | 3/16″ noma ngaphezulu |
30 | 1/8″ noma ngaphezulu |
36 | 3/32″ noma ngaphezulu |
46 | 3/32″ noma ngaphezulu |
54 | 1/16″ noma ngaphezulu |
60 | 1/16″ noma ngaphezulu |
70 | 1/16″ noma ngaphezulu |
80 | 1/16″ noma ngaphezulu |
90 | 1/16″ noma ngaphezulu |
100 | 1/16″ noma ngaphezulu |
120 | 1/16″ noma ngaphezulu |
150 | 1/16″ noma ngaphezulu |
180 | 1/16″ noma ngaphezulu |
220 | 1/16″ noma ngaphezulu |
240 | 1/16″ noma ngaphezulu |
3. Usayizi kanye Nohlobo Lwe-Air Compressor
Usayizi nohlobo lwe-compressor yakho yomoya kudlala indima ebalulekile ekunqumeni usayizi wombhobho. Amandla we-compressor okuletha umthamo womoya, olinganiswa ngama-cubic feet ngomzuzu (CFM), athinta ukucindezela okukhiqizwa ku-nozzle. I-CFM ephakeme ivumela umlomo wombhobho okhudlwana kanye nesivinini esibi kakhulu. Kubalulekile ukuqinisekisa ukuthi i-compressor yakho ingakunikeza i-CFM edingekayo yosayizi wenozzle oyikhethile.
4. Ingcindezi kanye nesivinini seNozzle
Ingcindezi kanye nesivinini somlomo wombhobho kudlala indima ebalulekile ekunqumeni ukusebenza kahle kokuqhunyiswa kwesihlabathi. Ingcindezi, evame ukukalwa nge-PSI (Amakhilogremu nge-Inch yesikwele), ithinta ngqo isivinini sezinhlayiya ezihubhukayo. Ukucindezela okuphezulu kubangela ukwanda kwesivinini sezinhlayiyana, kunikeze amandla amakhulu e-kinetic phezu komthelela.
5. Izidingo Eziqondile Zokufaka Isicelo
Uhlelo ngalunye lwe-sandblasting lunezidingo zalo ezihlukile. Isibonelo, umsebenzi wemininingwane eyinkimbinkimbi ungase udinge usayizi wombhobho omncane ukuze uzuze imiphumela enembayo, kuyilapho izindawo ezingaphezulu ezingaphezulu zingase zidinge usayizi wombhobho omkhulu ukuze umbozwe kahle. Ukuqonda izidingo ezithile zohlelo lwakho lokusebenza kuzokusiza ukuthi unqume usayizi wombhobho ofaneleka kakhulu.
Ngokucabangela lezi zici futhi uthole ibhalansi elungile, ungakhetha usayizi wenozi ofanele wohlelo lwakho lokusebenza lwe-sandblasting, uqinisekisa imiphumela esebenza kahle nangempumelelo kuyilapho ukhulisa isikhathi sokuphila semishini yakho.
Isibonelo, Ukugcina ingcindezi yenozzle eyi-100 psi noma ngaphezulu kubalulekile ukuze kukhuliswe ukusebenza kahle kokuhlanza ukuqhuma. Ukwehla ngaphansi kwe-psi eyi-100 kungaholela ekwehleni okucishe kube ngu-1-1/2% ekusebenzeni kahle kokuqhuma. Kubalulekile ukuqaphela ukuthi lokhu ukulinganisa futhi kungase kuhluke ngokusekelwe ezicini ezifana nohlobo lwe-abrasive esetshenzisiwe, izici ze-nozzle nepayipi, nezimo zemvelo ezifana nomswakama nezinga lokushisa, okungaba nomthelela kwikhwalithi yomoya ocindezelweyo. Qinisekisa ukungaguquguquki nokwanele kwengcindezi yenozzle ukuze uthuthukise ukusebenza kwakho kokuqhuma.
