Isishwankathelo se-Foam Concrete

Inkqubo yokwenza izitena ye-CLC

Kwimveliso yekhonkrithi ye-foam yendabuko, i-ejenti yogwebu lwesamente iyanyibilika. Ijenereyitha yogwebu isetyenziselwa ukuxuba ugwebu oluveliswe yilo eludaka oluqulunqwe ngezinto zesamente kunye nemixube esetyenziswa kwikhonkrithi.. Ikhonkrithi ye-foam ene-micropores ifunyenwe emva kokuxuba, ukuphosa, ukubumba, kunye nokunyanga.

Iimpawu zekhonkrithi ye-foam

Uxinzelelo lwekhonkrithi yegwebu malunga 500-1200 kg/m3; I-thermal conductivity ngokubanzi 0.12-0.30 W/(m·k).Amandla oxinzelelo ngokubanzi 3-14 MPa, kwaye isoloko isetyenziswa njengomaleko wokugquma amaphahla, iindonga ezizixhasayo, kunye nemibhobho eshushu. Ikhonkrithi ye-foam ye-ultra-light yangoku inobuninzi obuphantsi kakhulu kunye ne-thermal conductivity, kunye nokusebenza kwayo kwe-thermal kuhle kakhulu, njengokuxinana kwe 80 kg/m3.I-thermal conductivity yekhonkrithi enegwebu yi 0.040 W/(m·k); i-thermal conductivity yekhonkrithi enegwebu kunye nobuninzi be 100 kg/m3 yi 0.043 W/(m·k); i-thermal conductivity yekhonkrithi enegwebu kunye nobunzima 120 kg/m3 yiyiyo 0.047 W/(m·k). Ngoku, emhlabeni, ukuba izinto eziphathekayo zine-conductivity ephantsi ye-thermal, ingabizwa ngokuba yi-insulation material. I-thermal conductivity ye-high-efficiency insulation materials kufuneka ibe ngaphantsi 0.05 W/(m·k). Ikhonkrithi ye-foam ekhanyayo isetyenziswe njengesixhobo sokugquma se-thermal esiphezulu, ukusebenza kwayo kuthelekiseka ngokupheleleyo nezinto eziphilayo zokugquma i-thermal ezifana ne-polyurethane kunye ne-polystyrene, kwaye ngenxa ye-coefficient yayo ephezulu yokubuyiswa komlilo, ubomi benkonzo ende.

Irhasi enetyhefu ngoku iye yaba yimveliso edumileyo yezinto zokwakha zokugquma kwaye sele iqalisile ukubuyisela ngokuthe ngcembe imathiriyeli yokufakelwa kwezinto eziphilayo kwimarike., ibe yeyona nto ithandwayo kushishino lokugquma izakhiwo.

Enye inkcazo yekhonkrithi ye-foam: sebenzisa isamente, imixube, njl. njengeyona nto iphambili yesamente, yongeza amanzi kunye nomxube wekhonkrithi ye-foam ukulungiselela i-slurry, kwaye emva koko ugwebe kwi-ejenti yogwebu lwesamente, phosa, ukumila, kunye nokunyanga ukwenza inani elikhulu elincinci, ezizimeleyo, Ikhonkrithi yegwebu ekhaphukhaphu enamaqamza asasazwa ngokufanayo.

Ukucaciswa kwekhonkrithi yegwebu

(1) Ukuhlelwa ngokomahluko kubuninzi

Ikhonkrithi ye-foam ye-thermal: Ikhonkrithi yegwebu isetyenziswa ikakhulu kwi-thermal insulation. Ngesiqhelo, Ikhonkrithi enagwebu kunye noxinaniso olukhulu lwe 400 kg/m3 okanye ngaphantsi. Ikhonkrithi ye-foam ye-ultra-light eyenziwe kwiminyaka yamuva ineempawu zokugcinwa kobushushu obusebenzayo.

Ikhonkrithi ye-foam ethwele umthwalo: Isetyenziswe njengento ethwala umthwalo, kwaye inokugcina umbane kunye nesiphumo sokugquma kwe-thermal. Ngesiqhelo, kukuxinana kwesambuku.

Ikhonkrithi enegwebu ngaphezulu 700 g/m3.

Ukuthwala imithwalo kunye nokugcina ukushisa kwekhonkrithi ye-foam: Isetyenziswe njengekhonkrithi ye-foam yokuzimela. Ngesiqhelo, Ikhonkrithi enagwebu kunye noxinaniso olukhulu lwe 500-600 kg/m3.

(2) Ukwahlula ngokweendlela ezahlukeneyo zogwebu

Ngokwasemzimbeni ugwebu lwesamente: I-ejenti yogwebu lwekhonkrithi: into ekhupha amagwebu kwikhonkrithi, esekelwe kwi-surfactants, ifakwe amagwebu ngejenereyitha ye-foam kwaye ixutywe ne-slurry edibeneyo. Ubuninzi bekhonkrithi ye-foam buhlengahlengiswa ngokutshintsha inani leebhubhu. Ikhonkrithi yogwebu elungiselelwe yile ndlela inomsebenzi olungileyo wokwakha kodwa ixhomekeke kakhulu kumatshini ogwebu amagwebu.

Ikhemikhali igwebu eligwebu ikhonkrithi: Sebenzisa i-hydrogen peroxide okanye umgubo we-aluminiyam ukukhulula igesi ngokusabela kwekhemikhali ukwenza ikhonkrithi yogwebu. Ubushushu bekhonkrithi kunye nokuhambelana kwe-slurry kuya kuchaphazela ixesha le-foaming kunye nomthamo we-foaming, enokuthiwa i-post-foaming.

Ikhonkrithi enegwebu emva kokuxuba: sebenzisa i-surfactants, Izilwanyana ezisekelwe kwiprotheyini kunye nezityalo ezikhupha amagwebu, njl. ukuba ibandakanywe kumxube,

Ukuvuselela kunye ne-slurry, le yindlela yokwenza amaqamza ngokuqala. Ixesha layo lokuxuba, isantya sokuxuba, ugxininiso.

Ukutshintsha kobungakanani bezinto eziphathekayo kunye nezinye izinto zinokulungisa umxholo womoya, kunye nokusebenza kunokufezekiswa kuphela ngokuvuselela.

(3) Ngokweentlobo ezahlukeneyo zee-aggregates

Isuntswana lepolystyrene ikhonkrithi enegwebu isebenzisa amasuntswana epolystyrene njengeaggregate, yixube kunye nodaka oluludaka lwekhonkrithi, xuba kwaye ugalele.

Ikhonkrithi yegwebu yenziwe ngesitofu.

I-perlite eyandisiweyo ikhonkrithi enegwebu: ikhonkrithi enogwebu eyenziwe ngokusebenzisa iperlite eyandisiweyo njengeaggregate. Ngaphandle koko, kukho ikhonkrithi ye-foam edibeneyo ekhaphukhaphu elungiselelwe ngamasuntswana e-polyurethane, amasuntswana e-phenolic resin, amasuntswana vitrified microbead, kunye ne-vermiculite.

(4) Ngokohlelo olwahlukileyo lwenkqubo yokuvelisa

Ifektri esele yenziwe ikhonkrithi yogwebu: ibhekisa kwikhonkrithi yogwebu esele yenziwe kwimizi-mveliso yeekhemikhali ezikhethekileyo, njengebhodi yokugquma ikhonkrithi enogwebu,

Iibhloko ze-CLC kunye neepaneli zodonga lwekhonkrithi egwebu, njl.

Kwisiza ukugalelwa ikhonkrithi enegwebu: njengomaleko wokugquma ubushushu bomhlaba, umgangatho wokufudumeza umgangatho we-thermal insulation, umphezulu wodonga lokugalela kunye nokuzaliswa komthamo omkhulu.

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.
