Ukugeleza kwenqubo ye-plastic guardrail net ecwilisiwe imi kanje:
I-workpiece yehliswa futhi ishiswe ngaphambili ibe ngaphezu kwendawo yokuncibilika ye-powder coating. Ngemva kokucwiliswa embhedeni onoketshezi, impushana yepulasitiki izonamathela ngokulinganayo, bese i-polymer eyenziwe ngepulasitiki ixhunywe ngokuphambana futhi ihlelwe ibe umkhiqizo oyinhlanganisela yensimbi-yepulasitiki.
Umgomo we-plastic guardrail net ocwilisiwe umi kanje:
Ukucwiliswa kwempushana kwaqala endleleni yombhede omanzi. Umbhede onoketshezi waqala ukusetshenziswa ekuboleni kokuxhumana kwe-petroleum ejeneretha yegesi iWinkler. Khona-ke inqubo yokuxhumana yesigaba esiqinile-yegesi yathuthukiswa, futhi kamuva yasetshenziswa kancane kancane ekuhlanganisweni kwensimbi. Ngakho-ke, ngezinye izikhathi kusabizwa ngokuthi "indlela yokugqoka i-fluidized bed coating". Inqubo yangempela yokwengeza i-powder coating ibe yisitsha esinezimbotshana nesiphefumulayo (ithangi lokugeleza) ngezansi, futhi umoya ocindezelwe ophathwayo uthunyelwa usuka phansi nge-blower ukuze ugqugquzele ukumbozwa kwempushana ukuze kuzuzwe "ukugeleza". isimo” Iba impushana ecolekileyo esatshalaliswa ngokufanayo.
Umbhede onoketshezi yisigaba sesibili sombuso owuketshezi oluqinile (isigaba sokuqala yisiteji sombhede ongashintshi, futhi isigaba sesibili yisiteji sokuthutha umoya). Ngesisekelo sombhede ohleliwe, izinga lokugeleza (W) liyaqhubeka landa, futhi umbhede uqala ukwanda nokukhulula. Ukuphakama kombhede kuqala ukwanda, futhi inhlayiya ngayinye yempushana iyaphakanyiswa futhi isuke endaweni yayo yasekuqaleni kuze kube sezingeni elithile. Ngalesi sikhathi, ingena esiteji sombhede omanzi. Isigaba bc sibonisa ukuthi ungqimba lwempushana kumbhede omanzi luyakhula, futhi ukuphakama kwalo (I) kuyenyuka ngokunyuka kwesivinini segesi, kodwa ukucindezela (△P) embhedeni akunyuki, futhi izinga lokugeleza liyashintsha phakathi kwebanga elithile ngaphandle kokuthinta izinga lokugeleza koketshezi. Amandla eyunithi adingekayo ayisici sombhede omanzi, futhi yilesi sici esisetshenziselwa ukuqalisa inqubo yokumboza. Ukufana kwesimo se-powder fluidization embhedeni omanzi kuyisihluthulelo sokuqinisekisa ifilimu yokugqoka iyunifomu. Umbhede onoketshezi osetshenziswa embotsheni yempushana ungowokuthi "i-vertical fluidization". Inombolo ye-fluidization kufanele itholakale ngokuhlolwa. Ngokuvamile, kwanele ukukwazi ukugqoka. Izinga lokumiswa kwempushana embhedeni omanzi lingafika ku-30 kuya ku-50%.
