Izongezo zeConcrete eziKhala | Ii-Agents eziFoaming eziSebenza ngokuPhezulu kwiSellula Concrete
Xa kuthelekiswa neebhloko zekhonkrithi zemveli, iibhloko zekhonkrithi ezikhaphukhaphu zinamandla acinezelayo aphezulu, ukufunxwa kwamanzi okuphantsi kunye nomthamo ophantsi. Zikwakhaphukhaphu, Ixabiso eliphantsi kunye nokusingqongileyo.
Ibhloko eqhelekileyo ekhaphukhaphu inobunzima 22-28 iiponti, xa kuthelekiswa nebhloko yobunzima obuqhelekileyo enobunzima 19.5 iiponti. Zenziwa ngodongwe olwandisiweyo oludityanisiweyo okanye iincindi zentaba-mlilo. Zinokunyangwa kwiqondo lobushushu le-170-185degF, ngexesha lokuphumla 24 iiyure.
Iimathiriyeli ekrwada zilinganiswa nge-elektroniki phambi kokuba zixutywe kumxube. Zithi ke zixutywe nesanti, ikalika kunye nezinye izithako ukwenza uludaka. Umxube ugalelwe kwiimbumba zokubumba. Iibhloko ziyadityaniswa kwaye zityhalelwe ngaphandle kokubumba kwipalethi yentsimbi ecaba. Emva koko iibhloko zibekwe kwindawo yokugcina.
Ibhloko enesiphumo yenziwe ngumxube wesamente kunye nesanti kumlinganiselo malunga 30% ukuya 70%. Isanti yogqunywe ngomaleko wesarha ukuqinisa ukudityaniswa kwesamente esantini. Olu tyaba luthintela ukuvutha kwebhloko.
Inkqubo yokwenza ibhloko idinga ukubeka iliso rhoqo. Ubungakanani bomthamo wamanzi bulinganiswa kusetyenziswa iinzwa ze-ultrasonic. Ukuba amanzi avalelekile, isixa esongezelelweyo samanzi songezwa ukuze kuhlawulwe.
Ibloko iyanyangwa 12-18 iiyure kushushu, umoya omanzi. Emva koko ikhazimliswe nge-thermosetting resinous binder. Oku kunokubonelela ngempembelelo yokuhlobisa. Isenokuthi iqatywe nge-glaze ebhakiweyo. Imibala yemibala idla ngokudityaniswa ukunika ibhloko umbala ofanayo.
