Claydite: conductivity ezishisayo, izakhiwo kanye Ukucaciswa

ubumba Expanded, conductivity ezishisayo okuyinto buvezwa izinto zokusetshenziswa, has futhi ongaphakeme isisindo ethize futhi amandla aphezulu. Lezi zimfanelo kubangele endaweni ebanzi ukusetshenziswa kwale nto e wokwakha.

conductivity ezishisayo

Kulabo izinto zenzelwe ukwenza umsebenzi ukuphepha, lo ezishisayo conductivity isici kubaluleke ngokukhethekile. ubumba Expanded uba impahla yemvelo, yingakho le ipharamitha incike izimfanelo eziningana.

Phakathi usayizi okusanhlamvu lokuqala kufanele zabelwe. I umxhwele nakakhulu kungaba ingxenyenamba, aba maningi isidingo ukwahlukanisa. I porosity futhi umswakama okuqukethwe ubumba zandiswa futhi, sizothinta conductivity ezishisayo. Coefficient isilinganiso conductivity ezishisayo kunzima ukunquma ngoba kunezinhlobonhlobo. ubumba Expanded, okuyiqembu conductivity ezishisayo ku inkomba izincwadi elicacisiwe uhla 0,07 W / m, has hygroscopicity okusezingeni eliphezulu. Kodwa kungaba okufanelekile ukuba ukhombe futhi ukubaluleka esiphezulu conductivity ezishisayo - isifinyelele 0,16.

Kubalulekile ukukhetha impahla kwesokudla. Uma conductivity ezishisayo lingaphezulu, inani ukushisa lapho sidlula ungqimba yisivikelo iyamangalisa. Lokhu kubonisa ukuthi isihlangu ukushisa lehliselwa. Kufanele sinake nakwabangcwele porosity ubumba zandiswa esithinta kwabantu kanye conductivity ezishisayo. Ayanda kuyoba ithuba lokuqala, ephansi kuyoba ezimbili zokugcina.

Yini kuthinta isici esiyinhloko ubumba enwetshiwe

Ucwaningo luye lwabonisa ukuthi conductivity ezishisayo ubumba enwetshiwe kunqunywa ukungabi asebenza ngebhethri, kodwa ezingumphumela womkhiqizo esiteji inikezwe. Bocwepheshe kufanele inake ukukhiqizwa ngokukhethekile. Phela eziqukethwe Leca Silica kuthuthukisa conductivity ezishisayo, ngenkathi ezinye oxides yehlisa inani.

Lokhu akusebenzi amagesi imiswe phakathi Ukushisa okushisa puffing. Litholakala ukuthi uma ikhule ezimbotsheni eziqukethwe H ₂ + CO e isamba mkhulu kunezinhliziyo 55%, i-conductivity ezishisayo ubumba enwetshiwe kungaba izikhathi 2 ephakeme kunaleyo uma ukugcwala kuyoba emoyeni. On the conductivity ezishisayo kungathinta ngisho micropores. I ezincane abayikho, ephansi kuyoba conductivity ezishisayo, kodwa porosity lokhu kwebalingisi ayiphazamiseki.

izakhiwo Key

ubumba Expanded, conductivity kabani ezishisayo okukhulunywe ngaye ngenhla, anezakhi ezithile, phakathi kwabo:

• amandla okusezingeni eliphezulu;
• frost;
• ukuqina;
• Ukumelana umlilo;
• ibhalansi kahle izinga kanye nezindleko.

Uma ucabangela izinto, umuntu akakwazi ukuhlukanisa izimfanelo ukwahlukanisa okuhle, ukumelana acid chemical inertness. Leca kubhekwa a impahla yemvelo futhi imvelo yisivikelo ezishisayo.

imphawu letibalulekile

ukhonkolo block, kuyadingeka le conductivity ezishisayo zazo ukufunda ngaphambi yokufuna le nto has izimfanelo ezinhle. Wenziwe oluthambile nobumba futhi efanelekayo ukwakhiwa imvelo nobungane yesimanje.

Isetshenziswa ukhonkolo block nokungaphezulu zokuhlobisa, kodwa ekhaya kufanelekile ukuxazulula izinkinga izitshalo ezikhulayo. Nale impahla akwazi ukuqeda i anda umswakama ukuhwamuka, esiza ukulawula ibhalansi amanzi zezitshalo.

izici lobuchwepheshe

keramzita Coefficient conductivity ezishisayo isethwe ngezindinganiso isimo 9757-90, kanye nezinye ezibekiweko lobuchwepheshe, kufanele zabelwe phakathi kwengoma wamaqhuzu. On ukudayiswa ungathola impahla e amafraktjhini ezintathu:

• 5-10;
• 10-20;
• 20-40 mm.

Omunye akufanele bayakhohlwa esinye isigaba kwamafrakshini, okuyinto ngempela kuyaqabukela asetshenziswa emsebenzini wokwakha. Lezi zihlanganisa amatshe futhi lanwetshwa ubumba pellets kabani Ubukhulu isukela 2.5 kuya ku-10 mm. Kaningi lapho uthenga umthengi unesithakazelo kwabantu ngobuningi 7 ukusetha amanani lemikhiqizo kulo magazini:

• 250 kg / m ³ - 250 brand;
• kusukela kg 250 kuya ku-300 / m ³ - isitembu 300;
• analogously - sha 350, 400, 450, 500, 600.

Ukuze ukudayiswa jikelele brand ezimbili ezilandelayo azitholakali, zenziwa kuphela ngokuxhumana ikhasimende. ubumba Expanded, izici, conductivity ezishisayo, okuyinto okukhulunywe ngaye esihlokweni, futhi kufanele abe nesithakazelo kuwo umthengi has a ikakhulukazi compaction isilinganiso, okuyinto esihlelwe ngamunye, kodwa ukubaluleka asisikhulu kunenkosi 1.15. Kuvele ipharamitha ezibalulekile inquma ukuziphatha ubumba enwetshiwe lapho zihlatshwa umswakama, kuyinto ukumuncwa amanzi. It ziyahlukahluka kusuka 8 kuya ku-20%.

Ukuqhathaniswa conductivity ezishisayo ubumba enwetshiwe namanye izinto

ubumba Expanded, conductivity ezishisayo (Ukuqhathanisa lesi sici nezinye izinto futhi okufanele iqhutshwe ngaphambi kokwenza ukukhethwa impahla) okuyinto sesivele eshiwo ngenhla, ngokuvamile olufuna abathengi uvolo amaminerali noma Perlite ukunwetshwa. Esimweni sokuqala, Coefficient kuyinto 0.04, okhombisa ukuthi ukushuba efanayo noboya izokhipha ukushisa kancane, uma kulinganiswa nokwenu ubumba ukunwetshwa.

Enye ehlukile - ke unwetshiwe Perlite. ukumuncwa amanzi awo ngaphansana ubumba enwetshiwe futhi% 5 kuphela, kanti conductivity ezishisayo ka 0.04 kuphela.

Expanded ubumba, izakhiwo, conductivity ezishisayo, okuyinto ngezinye izikhathi zenza kube i material zibalulekile ngemisebenzi, ngezinye izikhathi ngisho kuqhathaniswa vermiculite. He is ukhetho best, esizokujamiselela ukhonkolo block, futhi kukhiqizwa edwaleni, okwenza kube imvelo. conductivity ezishisayo of vermiculite enwetshiwe kuyinto 0.08, okuyinto kancane izikhathi 2 ngokuziqhathanisa uvolo amaminerali. Uma le nto isetshenziswa, kungenzeka ukwakha ungqimba ezondile backfill, okuzokwenza ukulayisha ukugqagqana kancane. Kuthiwa lesi ukwahlukanisa kungaba futhi njengesisekelo izibopho.

isiphetho

I conductivity ezishisayo uba omunye izici ezibaluleke ubumba ukunwetshwa. Kodwa-ke iyashesha esizimele imodi zokukhiqiza. Uma usebenzisa ubuchwepheshe ezivamile ukushintsha izinga ubumba enwetshiwe akuyona ikakhulukazi ukusebenza. Nokho, isicelo ubuchwepheshe banamuhla indlela uhlobo co-labadubuli noma ductile zinganezelwa izakhiwo nangokuvikela ubumba ukunwetshwa.
