Hose Sandblast Kū'ē Kiʻekiʻe i ka Abrasion i nā Abrasives
Hoʻohana ʻana i ka Hose Sandblast
Hoʻohana ʻia ia e wehe i ka ʻōpala ma luna o ka ʻili metala. Eia kekahi, kūpono ia no ka hana one pahū maloʻo a me ka hana one pahū pulu. Eia kekahi, kūpono ia no ka grit, slurry, concrete a me ka hoʻoili ʻāpana. ʻOiai lawelawe nui ia i loko o ke tunnel, metallurgy, mine, uapo a me ke kūlanakauhale. Pono ka mīkini one pahū, ka mīkini pahū pana a me ka mea puhi palaoa i kahi hose one pahū.
Wehewehena
Ma muli o ka NR a me ka mea hoʻoikaika kūikawā, loaʻa i ka hose oneblast ke kūpaʻa maikaʻi loa i ka abrasion. Eia kekahi, he palupalu loa ia. ʻOiai he mānoanoa maoli ka hose. ʻOiai ke ʻano maikaʻi a me ka hoʻoikaika ʻana o ka olonā tensile kiʻekiʻe e hāʻawi i ke kaomi kiʻekiʻe. I kēia manawa, ʻaʻole e wili ka hose. No ka uhi, he pale ʻaʻahu a pale i ka hopena ka rubber NR.
Nā ʻano o ka pahū one
ʻO kaʻoiaʻiʻo, ʻo ka hana oneblast he maloʻo a pulu. Hoʻohui ka wet blast i ka abrasive a me ka wai i loko o ka slurry. He mea ia e pale ai i ka popo metala. Akā, pono e loaʻa kahi mea pale i loko o ka wai. ʻOiai he mea pono loa ka dry blast. He ʻinoʻino ka ʻili me ka nui o ka lepo.
ʻO ke kumu nui loa, ʻo ke kūpaʻa ʻana i ka ʻaʻahu ke kumu o ka maikaʻi o ka hose sandblast. Pono ʻo ISO 4649 i ka nui o ka abrasion e emi ma mua o 140mm3. Akā, koi ʻo DIN 53561 i 60mm3.
Mea palekana o ka paipu oneblast
He hana weliweli ka hoʻopāpā one. No laila, pono ʻoe e kālele i kēia mau mea.
1. Ma mua o ka hana oneblast, pono ʻoe e ʻaʻahu i ke kapa pale. Eia kekahi, pono ma ka liʻiliʻi he 2 mau kānaka ma ke kahua.
2.5 mau minuke ma mua o ka hana, e hoʻomaka i ka mīkini wehe lepo. Akā inā hewa ka mīkini, ʻaʻole hiki iā ʻoe ke hana i ka hana one.
3. I ka wā o ka hana ʻana o ka mīkini pahū, ʻaʻole hiki i nā poʻe ʻē aʻe ke hoʻokokoke aku.
4. Ma hope o ka hana, pono e hana ka mīkini wehe lepo no 5 mau minuke hou aʻe. No ka mea hiki i kēia ke wehe i ka lepo i loko o ka hale hana a mālama iā ia i ka maʻemaʻe.
5. Ke hana ʻia kahi ulia, e hoʻōki koke i ka hana.
