Maitiro ekuyerera kweakanyudzwa epurasitiki guardrail net ndeaya anotevera:
Iyo workpiece yakasvibiswa uye inopisa kusvika pamusoro pekunyunguduka kwehupfu hwekuputira. Mushure mekunyudzwa mumubhedha wakanyungudika, hupfu hwepurasitiki hunonamatira zvakaenzana, uye ipapo iyo polima yepurasitiki inobatanidzwa uye inoiswa musimbi-yepurasitiki inoumbwa chigadzirwa.
Nheyo yekunyudzwa epurasitiki guardrail net ndeiyi inotevera:
Kunyudzwa kwehupfu kwakabva panzira yemubhedha inoyerera. Mubhedha wemvura wakatanga kushandiswa mukuora kwepetroleum muWinkler gasi jenareta. Ipapo iyo yakasimba-gasi maviri-chikamu chekubatanidza maitiro akagadzirwa, uye akazoshandiswa zvishoma nezvishoma mukuputira simbi. Naizvozvo, dzimwe nguva ichiri kunzi "fluidized bed coating method". Nzira chaiyo ndeyekuwedzera poda yekuputira mumudziyo une porous uye unofema (kuyerera tank) pasi, uye iyo yakabatwa yakamanikidzwa mhepo inotumirwa kubva pasi nemhepo inoputika kuti iwedzere hupfu hwehupfu kuti hubudirire "kuyerera". chinzvimbo”.Iva hupfu hwakatsetseka hwakagovaniswa zvakafanana.
Mubhedha wakanyungudutswa ndiyo nhanho yechipiri yemamiriro emvura yakasimba (nhanho yekutanga ndiyo nhanho yakagadziriswa yemubhedha, uye nhanho yechipiri ndiyo nhanho yekuyerera kwemhepo). Pamusoro pebhedha yakagadziriswa, kuyerera (W) kunoramba kuchiwedzera, uye mubhedha unotanga kuwedzera uye kusunungura. Kureba kwemubhedha kunotanga kuwedzera, uye imwe neimwe yehupfu inosimudzwa uye inofamba kubva panzvimbo yayo yepakutanga kusvika kune imwe nzvimbo. Panguva ino, inopinda muchikamu chemubhedha wemvura. Chikamu bc chinoratidza kuti poda yehupfu mumubhedha wemvura inowedzera, uye kureba kwayo (I) kunowedzera nekuwedzera kwegesi velocity, asi kudzvinyirira (△P) pamubhedha hakuwedzere, uye kuyerera kunoshanduka mukati mehumwe mutsara pasina kukanganisa kuyerera kwemvura. Iyo inodiwa unit simba hunhu hweiyo fluidized bed, uye ichi ndicho hunhu chinoshandiswa kuita iyo coating process. Kufanana kweiyo poda fluidization mamiriro mumubhedha wakanyungudutswa ndiyo kiyi yekuve nechokwadi cheunifomu yekuputira firimu. Mubhedha wakanyungudika unoshandiswa mukupoda poda ndewe "vertical fluidization". Nhamba ye fluidization inofanira kuwanikwa kuburikidza nekuedza. Kazhinji, zvakakwana kukwanisa kupfeka. Kumiswa kwehupfu mumubhedha wakasvibiswa kunogona kusvika ku30 kusvika ku50%.
