II a ni. Key hman dan thiamna leh thil tih dan tha ber berte chu large-scale sandblasting rooms .
Sandblasting room tha tak, sum leh pai leh him taka hman theihna tur atana hman dik leh enkawl that hi a bulpui ber a ni.
(1) Hnathawh hmaa inbuatsaihna leh ruahmanna siam .
Workpiece layout leh hoisting .
Sandblasting neih chhunga workpiece lut leh chhuahna tur kawng leh rotation/movement position te ruahman la, chu chuan surface zawng zawng chu a taka hman theih a nih theih nan.
Extra-a component sei (tower cylinder ang chi) atan chuan indoor ground rail leh sandblasting trolley te nen segmented sandblasting atan thawhhona tha tak neih a ngai a ni.
Sandblasting room san zawng chu a takin hmang la, batch part te te enkawl turin multi-layer suspension method hmang la, chu chuan space utilization rate a ti tha ang.
Abrasive thlan leh inbuatsaihna .
Process mamawh angin thlang rawh:
Metal abrasives (cast steel sand, wire cut shot) : Hardness sang, service life rei tak, recyclable, enkawlna tihchakna atana tha leh general rust removal.
Non-Metallic abrasives (brown corundum, quartz sand, garnet) : Hardness sang zawk leh cutting force chak zawk an nei a, stone harder rust layer emaw surface treatment atan an tha hle. Mahse, leivut tam tak an siam a, an chhe vek bawk.
Abrasives thar a vawi khatna atana hman a nih chuan an chhunga leivut leh bawlhhlawh awmte paih chhuah nan "empty run" cycle an neih a ngai a ni.
Abrasive mixing: Abrasives thar leh hlui hman hian proportion engemaw zat (3:7 ang chi) hmangin cutting efficiency a tichiang mai bakah cost a tihtlem thei bawk.
(2) Sandblasting process-a core technique hman dan .
Air pressure leh flow control .
Air pressure hian power source hna a thawk a: a tlangpuiin hnathawh pressure hi 0.6 leh 0.8 MPa inkar a awm a ngai a ni. Pressure hniam hian tihfai hna a thawk tlem hle. Pressure tam lutuk hian awlsam takin abrasive a tichhia thei a, equipment wear and tear a ti chak thei a, workpiece pawh a deform thei bawk.
Flow rate hi efficiency atana pawimawh ber a ni: Abrasive valve chu abrasive supply inang leh chhunzawm zel a nih theih nan siamrem tur a ni. Unstable flow hian surface roughness inang lo a thlen thei.
Spray gun hman dan tur .
Angle: Spray gun hi a tlangpuiin workpiece chunglam atanga 70℃atanga 80℃angle-ah a awm a (a vertical angle 90 degree-a spray khap tlat a ni a, a chhan chu crater thuk lutuk a thlen thei a ni). Flexible surface emaw thin plate emaw tan chuan angle a te zawk thei.
Distance: A tlangpuiin 300 leh 700 mm inkar a awm thin. A hlat lutuk a, chu chuan concentrated wear na tak leh roughness lian tak a thlen thin. A hlat lutuk a, energy a hloh a, efficiency a hniam bawk.
Movement Speed leh Trajectory: Movement speed nghet leh inang tlang tak vawng reng la, transverse emaw longitudinal overlapping sweeping (1/3 vel a overlap nei) hmang la, omission emaw local overspraying emaw a awm loh nan.
