Claydite: matenthedwe madutsidwe, katundu ndi specifications

Kukodzedwa dongo, matenthedwe madutsidwe amene makamaka anatsimikiza ndi zipangizo, nayenso otsika kulemera yeniyeni ndi mphamvu yapamwamba. makhalidwe amenewa chifukwa dera lalikulu la ntchito za nkhaniyi zomangamanga.

matenthedwe madutsidwe

Zipangizo amene apangidwa kuchita ntchito chitetezo, ndi matenthedwe madutsidwe khalidwe n'kofunika kwambiri. Kukodzedwa dongo amachita ngati zinthu zachilengedwe, nchifukwa chake chizindikiro ichi zimadalira ndi makhalidwe ena angapo.

Mwa oyambirira kukula mbewu ayenera allocated. The chidwi kwambiri kuti kagawo, wamkulu kufunika kutchinjiriza. The porosity ndi mnyontho dongo kukodzedwa, nayenso, zidzakhudza madutsidwe matenthedwe. The koyefishienti avareji madutsidwe matenthedwe zovuta kudziwa chifukwa pali zinthu zosiyanasiyana. Kukodzedwa dongo, amene madutsidwe matenthedwe mu Buku mabuku zafotokozeredwa osiyanasiyana 0,07 W / m, ali mkulu hygroscopicity. Koma izo zikanakhala chilungamo kuwalozera ndi mtengo pazipita madutsidwe matenthedwe - akafika 0,16.

Nkofunika kusankha zinthu bwino. Ngati madutsidwe matenthedwe ndi apamwamba, kuchuluka kwa kutentha wakupambana mwa insulator wosanjikiza ndi kokwanira. Zimenezi zikusonyeza kuti zotchinga kutentha ndi adatchithisira. Kodi kulabadira kwa porosity wa dongo kukodzedwa, izi zimakhudza kachulukidwe ndi matenthedwe madutsidwe. The apamwamba adzakhala njira choyamba, m'munsi adzakhala awiri otsiriza.

Kodi zimakhudza khalidwe waukulu wa dongo kukodzedwa

Kafukufuku wasonyeza kuti madutsidwe matenthedwe dongo kukodzedwa anatsimikiza chifukwa analibe khwatsi, koma pa siteji iliyonse kupanga. Technologists ayenera kuganizira kupanga makamaka. Ndipotu ali silika Leca bwino matenthedwe madutsidwe, pamene oxides ena kuchepetsa phindu.

Izi sizikhudza ku mipweya anapanga pa Kutentha kwa puffing kutentha. Umapezeka kuti ngati pores ali H ₂ + NKHA mu ndalama kuposa 55%, ndi madutsidwe matenthedwe dongo kukodzedwa adzakhala nthawi 2 kuposa ngati chidzalo adzakhala mpweya. Pa madutsidwe matenthedwe zingakhudze ngakhale micropores. Ang'onoang'ono iwo ali, m'munsi adzakhala matenthedwe madutsidwe, koma porosity wa mapangidwe izi si bwanji.

katundu Ofunika

Kukodzedwa dongo, amene matenthedwe madutsidwe anali tatchulazi, ali katundu wina pakati pawo:

• mkulu mphamvu;
• chisanu;
• durability;
• moto kukana;
• mulingo woyenera muyezo wa khalidwe ndi mtengo.

Poganizira nkhani, sangathe kusiyanitsa makhalidwe abwino kutchinjiriza, kukana acid ndi mankhwala inertness. LECA imatengedwa zakuthupi zachilengedwe ndi wochezeka matenthedwe insulator.

mbali Ofunika

Konkire chipika, ndi matenthedwe madutsidwe amene amafunikira kuphunzira pamaso kupeza nkhaniyi ali ndi makhalidwe abwino kwambiri. Zikhale za shale ndi dongo oyenera wochezeka ndi zamakono yomanga.

Ntchito chipika simenti ndi zina zolinga kukongoletsa, koma kunyumba ndi oyenera pothetsa mavuto a mbewu kukula. Ndi nkhaniyi okhoza kuthetsa kochulukira chinyezi evaporation, amene amathandiza kuletsa madzi bwino zomera.

makhalidwe luso

keramzita koyefishienti wa madutsidwe matenthedwe walembedwa ndi mfundo boma 9757-90, komanso specifications ena luso, iwo ayenera allocated mwa zikuchokera fractional. Akugulitsa mungapeze nkhani tuzigawo twa zitatu:

• 5-10;
• 10-20;
• 20-40 mm.

Mmodzi Tisaiwale za gulu lina la tizigawo, amene kawirikawiri ndithu ntchito pa ntchito yomanga. Zikuphatikizapo miyala bwereza pellets dongo amene miyeso osiyanasiyana monga 2.5 10 mm. Nthawi zambiri pamene kugula katundu ndi chidwi kachulukidwe ndi chochuluka 7 kukhazikitsa mfundo za zopangidwa mu nkhani iyi:

• kuti makilogalamu 250 / mamita ³ - 250 mtundu;
• kuchokera makilogalamu 250 300 / mamita ³ - sitampu 300;
• analogously - mtundu 350, 400, 450, 500, 600.

Pakuti malonda ambiri izi zopangidwa ziwiri palibe, iwo anapanga okha mogwirizana ndi makasitomala. Kukodzedwa dongo, makhalidwe, matenthedwe madutsidwe, amene tamutchula m'nkhani, ndipo ayenera kukhala ndi chidwi ogula ali inayake compaction chiŵerengero, amene mgwirizano payekha, koma mtengo sali wamkulu kuposa 1,15. An chizindikiro zofunika kumene kumatsimikizira khalidwe la dongo kukodzedwa atadziŵa chinyezi, ndi mayamwidwe madzi. Iwo akhoza zimasiyana 8 mpaka 20%.

Kuyerekezera madutsidwe matenthedwe dongo kukodzedwa ndi zina zipangizo zina

Kukodzedwa dongo, matenthedwe madutsidwe (Kuyerekezera khalidwe ndi zipangizo zina iyenera kuchitikira asanayambe kuchita kusankha zinthu) zomwe kale tatchulazi, nthawi zambiri ankakonda ndi ogula mchere ubweya kapena kukodzedwa perlite. Mbali yoyamba, ndi koyefishienti ndi 0,04, zimene zikusonyeza kuti kwa makulidwe yemweyo wa nkhosa adzamasula zochepa kutentha poyerekeza ndi dongo kukodzedwa.

njira ina - ndi kukodzedwa perlite. madzi mayamwidwe poyerekeza dongo kukodzedwa ndi zochepa 5%, pamene madutsidwe matenthedwe wa 0,04 yekha.

Kukodzedwa dongo, katundu, matenthedwe madutsidwe, omwe nthawi zina kuti zinthu zakuthupi chofunika kwambiri pa ntchito, nthawi zina poyerekeza ndi vermiculite. Iye ndiye njira yabwino, zimene m'malo chipika konkire, ndipo amapangidwa kuchokera thanthwe, kupanga izo wochezeka. Matenthedwe madutsidwe wa kukodzedwa vermiculite ndi 0,08, lomwe nthawi 2 zochepa poyerekeza ndi ubweya mchere. Ngati nkhaniyi ntchito, n'zotheka kupanga wosanjikiza zonyalazo backfill, umene katundu alipo zochepa. Akuti ntchito kutchinjiriza zingakhale komanso monga maziko zikulumikizana.

Pomaliza

The madutsidwe matenthedwe amachita monga la makhalidwe ofunika dongo kukodzedwa. Koma kwambiri osadalira pa akafuna kupanga. Ngati inu ntchito luso ochiritsira kusintha khalidwe la dongo kukodzedwa si makamaka ntchito. Komabe, kugwiritsa ntchito njira zamakono za njira mtundu co-mfuti kapena ductile zotheka kuonjezera katundu chimateteza dongo kukodzedwa.
