Phosphating inzira yekugadzira phosphate kemikari inoshandura firimu kuburikidza nemakemikari uye electrochemical reactions, uye yakaumbwa phosphate inoshandura firimu inonzi phosphating firimu. Chinangwa chikuru chephosphating ndechekudzivirira simbi yepasi uye kudzivirira simbi kubva pakusvibiswa kusvika pamwero wakati; Inoshandiswa priming isati yapenda kuti ivandudze adhesion uye corrosion resistance yepende yefirimu; Inoshandiswa kuderedza mafuta firimu lubrication panguva yesimbi inotonhora yekushanda maitiro.
Phosphating inzira inowanzo shandiswa pre-kurapa. Muchidimbu, inofanirwa kuve yemakemikari ekushandura membrane kurapwa. Chero bedzi ichishandiswa kune phosphating yenzvimbo dzesimbi, zvisiri-ferrous simbi senge aluminium uye zinc zvinogona zvakare kuiswa kune phosphating. Maitiro ekunyudza chidimbu chebasa (simbi, aruminiyamu, kana zingi) mune phosphating mhinduro (imwe acidic phosphate based solutions) uye kuisa musara weinsoluble crystalline phosphate conversion firimu pamusoro inonzi phosphating.
Blackening inzira yakajairika yesimbi kupisa kurapwa. Nheyo yacho ndeyekugadzira dhizaini ye oxide firimu pane simbi pamusoro kuti iparadzanise mweya uye kuzadzisa chinangwa chekudzivirira ngura. Kana izvo zvinodikanwa zvekutaridzika zvisiri kukwirira, kurapa kwakasviba kunogona kushandiswa. Pamusoro pezvikamu zvesimbi zvinoshanduka zvitema, zvimwe zvacho zvinonzi bhuruu. Bluing kurapwa ikemikari pamusoro pekurapa. Basa rayo guru nderokugadzira dense oxide firimu pamusoro pebasa rekushanda, kudzivirira kuparara uye ngura, uye kuvandudza kupfeka kupikisa kwe workpiece. Kurapa kwepamusoro chete hakuzokanganisa chimiro chemukati. Haisi kurapwa kwekupisa, kwakasiyana zvakanyanya nekudzima.
High simba mabhaudhi anoshandisa phosphating, iyo inogona zvakare kudzivirira hydrogen embrittlement nyaya. Naizvozvo, mabhaudhi ari pamusoro pegiredhi 10.9 mumunda weindasitiri anowanzo shandisa phosphating pamusoro pekurapa. Blackening + oiling ijairo rine mukurumbira rezvitsigiro zvemaindasitiri nekuti ndiyo yakachipa uye inotaridzika zvakanaka isati yashandiswa mafuta. Nekuda kwekusviba kwayo, inenge isina simba rekudzivirira ngura, saka ichaita ngura nekukurumidza pasina mafuta.
Kuti uwane rumwe ruzivo nezve drywall misumari, ndapota taura nesu.
