Izithasiselo zikakhonkolo ezingasindi | Ama-ejenti Akhipha Amagwebu Asebenza Kakhulu Wokhonkolo Weselula
Uma kuqhathaniswa namabhulokhi kakhonkolo wendabuko, amabhlogo kakhonkolo angasindi anamandla acindezelayo aphezulu, ukumuncwa kwamanzi okuphansi kanye nevolumu ephansi. Abuye alula, engabizi kakhulu futhi enobungani nemvelo.
Ibhulokhi engasindi evamile inesisindo 22-28 amaphawundi, uma kuqhathaniswa nebhlokhi enesisindo esijwayelekile enesisindo esimayelana 19.5 amaphawundi. Zenziwe ngezingxube zobumba ezinwetshiwe noma izinsimbi zentaba-mlilo. Zingelapheka ngebanga lokushisa elingu-170-185degF, ngesikhathi sokukhulelwa 24 amahora.
Izinto zokusetshenziswa zikalwa nge-elekthronikhi ngaphambi kokuthi zixutshwe ku-mixer. Bese behlanganiswa nesihlabathi, i-lime nezinye izithako zokwenza i-slurry. Ingxube ithululelwa isikhunta ukuze kwakhiwe. Amabhulokhi abe esehlanganiswa futhi aphushelwe ngaphandle kwesikhunta ku-pallet yensimbi eyisicaba. Amabhulokhi abe esebekwa endaweni yokugcina.
Ibhulokhi ewumphumela yakhiwe ngengxube kasimende nesihlabathi ngesilinganiso esingaba 30% ku 70%. Isihlabathi simbozwa ungqimba lwe-sawdust ukuze kuthuthukiswe ukuhlangana kukasimende esihlabathini. Lokhu kunamathela kuvimbela ibhulokhi ekushiseni.
Inqubo yokwenza i-block idinga ukuqapha njalo. Inani lokuqukethwe kwamanzi likalwa kusetshenziswa izinzwa ze-ultrasonic. Uma amanzi evalelekile, umthamo owengeziwe wamanzi wengezwa ukuze unxephezele.
Ibhulokhi iyalapheka 12-18 amahora ekushiseni, umoya omanzi. Ibe isicwebezeliswa nge-thermosetting resinous binder. Lokhu kunganikeza umphumela wokuhlobisa. Kungase futhi kuhlanganiswe ne-glaze ebhakiwe. Izingulube zombala zivame ukungezwa ukunikeza ibhulokhi umbala ofanayo.
