Izongezo zeConcrete eziKhala | Ii-Agents eziFoaming eziSebenza ngokuPhezulu kwiSellula Concrete
I-arhente yogwebu lwesamente ikakhulu yahlulwe yaba ziindidi ezimbini: one is the plant cement foaming agent another is animal performance foaming agent.How do you choose these two blowing agents? Makhe sijonge umahluko phakathi kogwebu lwesamente yesityalo kunye ne-ejenti yogwebu lwesilwanyana .
1. I-agent yesamente yokutyala ugwebu: Ugwebu lwesamente yemifuno yenziwe ngezinto eziphuma kumazwe angaphandle ezikumgangatho ophezulu wezityalo zendalo zepolymer, eveliswa luthotho lweekhemikhali ezintsonkothileyo. Imveliso lulwelo oluluthuthu tyheli olusulungekileyo oluneoyile. Ayinamvakalelo kumanzi aqinileyo, non-toxic, engenavumba, akukho ntlenga. Ixabiso le-PH likufutshane nokungathathi hlangothi, i-non-corrosion kwi-samente kunye nesinyithi, kwaye ayingcolisi okusingqongileyo.
Iingenelo: I-agent ekhupha ugwebu iyamelana nokugcinwa, ayiwohloki lula, ineempawu ezibalaseleyo zogwebu, utyebile ngamagwebu, kwaye inozinzo oluphakathi lwamagwebu. I-samente enegwebu eyenziwe nge-ejenti yogwebu ineempawu zokusetyenziswa okuphantsi, ixabiso eliphantsi kunye nomgangatho ozinzile. Umphanda ugwebu ugwebu (200ikg) inokuvelisa malunga 500 cubic metres yesamente enegwebu, ngoko isetyenziswa ngokubanzi kwiiprojekthi zokufudumeza umgangatho. Kwiprojekthi yokufaka uphahla, iindleko zokwakha zinokuncitshiswa kakhulu.
Iingxaki: Ekubeni i-samente enegwebu eyenziwe ye-agent e-foam ine-pore shape yangaphakathi eqhubekayo, I-samente enegwebu inokungena kakuhle kwegesi kunye nokunganyangeki kakuhle, kwaye ayinakusetyenziswa kubunjineli bokunganyameki kwamanzi. Xa kuthelekiswa nesamente enogwebu eyenziwe ngamagwebu esilwanyana ngokuxinana okufanayo, ukusebenza kwayo ukugquma thermal kunye namandla compressive zonakaliswe kancinane, ngoko inqunyelwe kwezinye izicelo ezineemfuno ezizodwa. Ngenxa yokuzinza kwe-foam ye-agent ye-foam yemifuno, ubukhulu be-samente ene-foam ye-casting yexesha elilodwa ngokubanzi abudluli 200 mm, kungenjalo ukuwohloka komphezulu kunokwenzeka ukuba kwenzeke.
2 Ugwebu lwesamente yezilwanyana: i-agent ye-samente yezilwanyana kunye nesilwanyana esikhethiweyo (inyama yenkomo, iigusha) iprotheni ye-keratin njengeyona nto iphambili, emva kothotho lweempendulo ze-hydrolysis, ukufudumeza kunyibilikile, ixutywe, ihluziwe, ukuncipha kobushushu obuphezulu. Iveliswa ngezixhobo zogwebu kunye nenkqubo yokuvelisa. Inkqubo yemveliso ingqongqo yolawulo lomgangatho. Imveliso ngulwelo olumnyama lwe-viscous, umxholo ophantsi wokungcola, ivumba elikhanyayo elicaphukisayo, umgangatho ofanayo, umgangatho olungileyo ukuhambelana, ugwebu oluhle kunye nolugqwesileyo Uzinzo lwegwebu sisizukulwana esitsha se-agent yesamente yezilwanyana ekhupha amagwebu.
Iingenelo:
Xa kuthelekiswa nesamente enogwebu eyenziwe ngemifuno ekhupha amagwebu, inomsebenzi ongcono wokutywina kunye nokumelana nobushushu obuphezulu kuxinaniso olufanayo. Ngenxa yokuzinza kwayo okugqwesileyo kogwebu, isamente yayo enegwebu ezilahlwayo inokufikelela ngaphezu 1.5 iimitha ngaphandle kokuwa, ngoko ifanelekile ukuveliswa kwezitena ze-foam, iipaneli ezilula kunye neendonga ezilula.
Iingxaki:
Ngenxa yenkqubo yemveliso enzima, ixabiso lemveliso liphezulu. Isixhobo sokuvuthela asibibi kangako ugwebu kunemifuno ekhupha ugwebu, kwaye ukusetyenziswa kwesamente enegwebu kuphezulu. Inevumba elithile elirhabaxa kwaye inokunyamalala kuphela emva kokuba yenziwe isamente enogwebu.
I-Cie-China.org ngumboneleli okhokelayo wezongezo zekhonkrithi zogwebu obonelela ngearhente yogwebu, superplasticizer,isixhasi samandla ekhonkrithi enogwebu kwikhonkrithi ekhaphukhaphu, Iibhloko ze-CLC. Ukuba ukhangela iarhente yogwebu, nceda uzive ukhululekile Qhagamshelana nathi.
