Sand: A specifications chilinganizo. mchenga kwa yomanga

Sand, chilinganizo chimene chiri motere: SiO2, ndi phiri nyanja miyala ndi zinthu yokumba ndi zikuchokera zinthu zina miyala. Nthawi zambiri tichipeza khwatsi woyera ndi mchere kuti ndi silika.

Today mchenga anapeza ambiri mbali zambiri zochita za anthu. Apa pamwamba zonse zofunikira kunyamula payekha ndi mafakitale yomanga. Sand chakhala mbali ya njira zosiyanasiyana mapangidwe maziko ndi kupaka pulasitala pamalo.

Kufotokozera mchenga

Natural mchenga - osakaniza lotayirira mbewu, nusu amene zimasiyanasiyana 0,16 5 mm. Zofunika anapanga pa yopuma thanthwe zovuta. Malinga ndi mmene kudzikundikira zinachitika, mchenga angakhale:

• deluvial;
• alluvial;
• Nyanja District;
• m'madzi;
• aeolian.

Motero, ntchito mitsinje ndi maiwe pali mchenga kuti ndi anamaliza ndi anamaliza mawonekedwe.

Makhalidwe chachikulu cha nyumbayi mchenga

Sand, chilinganizo imene tatchulazi - ndi lotayirira nonmetallic zakuthupi amene angagwiritsidwe ntchito kwa pafupifupi ntchito iliyonse yomanga. Zambiri za mchenga awa sali ongopangidwa khwatsi, komanso feldspar. Mu udindo zosafunika pano mchere dongo ndipo silicates.

Pa mchenga nthaka ndi zachilendo, onse mu nyanja ndi pa dziko. Porosity m'chigawo lotayirira pafupifupi 47%, koma kwa 37% wandiweyani. The kachulukidwe anayeza ndi koyefishienti wa porosity. Pakuti kagawo kakang'ono ka mchenga, mtengo uwu 0,75.

Mchenga, amene chilinganizo zingakhale zothandiza ogwira ntchito ali ndi porosity otseguka amene amapereka permeability khalidwe. Ngati mchenga yaikidwa zolimba, izo kulandira ndi kugawira katundu voteji pansi maziko. Gawo mapindikidwe mchenga yaing'ono kachigawo ranges ku 30 50 MPa.

Cholowa cha mitundu yosiyanasiyana ya mchenga

Sand, chilinganizo amene si kawirikawiri chofunika omanga nyumba, ali ndi ena yokoka yeniyeni, malinga zosiyanasiyana zipangizo. Ngati nyumba mchenga, ndiye mtengo uwu ndi 1.5 T / mamita ^3, pamene mita kiyubiki wa lotayirira youma matope mchenga adzakhala kulemera 1,44 m. Mu mawonekedwe ting'onoting'ono basi, mtengo uwu kuchuluka kwa 1,68 T / mamita ^3.

Chonyowa matope mchenga umalemera 1,92 T / mamita ^3, ndi ting'onoting'ono basi yonyowa yokoka mwachindunji 2,54 T / mamita ^3. mchenga misa zimasiyana ku mtsinje, khwatsi, m'madzi ndi miyala mitundu. Kulemera kwa mchenga awa adzakhala motere: 1.6; 1.6; 1,62; 1.5 T / mamita ^3, motero.

More za osalimba

Poganizira katundu wa mchenga, tisaiwale kuti limodzi la makhalidwe ofunika ndi osalimba ake. Ngati tikulankhula za mitundu chuma khwatsi, mbali anatsimikiza ndi njira ziwiri. Choncho, kachulukidwe chochuluka ndipo zikhoza kukhala zoona. Chochuluka anatsimikiza ndi unyinji kuti chiŵerengero buku m'chigawo chochuluka. Mu mtengo izi zikutanthauza osati mbewu komanso airspace. Khalidwe limeneli zingasiyane pa chinyezi.

Kumanga mchenga akhoza yodziwika ndi osalimba woona, phindu izi zonse ndipo anatsimikiza ndi chiŵerengero voliyumu ya thunthu mu boma wandiweyani. Pankhaniyi, chinyezi si zofunika. The kachulukidwe zimasiyanasiyana ndi mipweya ndi dongosolo maselo.

kachulukidwe choona cha chochuluka kwambiri. Kuuma, kumva kuwawa crushability ndi mchenga - ndi zizindikiro zotsalira za mphamvu. mayesero imachitika pa bwalo onsewo ndi akuvala kwa mtima wa magawo awa. The mbewu Choncho clamped umakaniko.

Standard ndi magawo yaikulu ya nyumbayi mchenga

Yomanga mchenga miyala ndipo lophatikizana ndi ubwamunalo linagawanika mu mtsinje. nkhani ino malinga ndi GOST 8736-93. Malinga ndi cholinga, khalidwe ndi magawo dekhetsa omwe amaonetsera zili dongo ndipo fumbi, zinthu zikhoza kugawidwa m'magulu awiri, omwe ali dongosolo yake yambewu.

Mankhwala opangidwa ndi mchenga wakhala tatchulazi, koma - osati kuposa akatswiri chidwi. Malinga ndi tirigu zikuchokera, zinthu zikhoza wachinsinsi ndi kukula. Kalasi yoyamba amatanthauza krupnofraktsionny mchenga, amene analandira mwa kuphwanya screenings. The kalasi chachiwiri mchenga si kwambiri coarse mchenga, komanso kakang'ono, sing'anga ndi mfundo zabwino.

Mchenga, amene mlendo uja tatchulazi, kungakhale komanso alluvial. Nkhanizi analandira posambitsa mchenga miyala. Ntchito madzi mu buku lalikulu, amene amalola kuthetsa nkhani dongo ndi ndalama. Alluvial mchenga angawauze pamaso pa ndalama ndi kukula 0,6 mm. Gwiritsani mtundu uwu mchenga kwa kupaka pulasitala, amene ndi osafunika pamaso pa dongo.

The gawo kukula kwa mchenga mtsinje

Mankhwala chilinganizo angathandize mchenga, koma sikawirikawiri kulabadira kwa mbuye payekha. Chofunika chizindikiro ndi tirigu dongosolo limene limanenedwa mwa m'ndandanda wa sieves ndi makulidwe mauna kuyambira 0,16 5 mm. mchenga wouma akudutsa sieve kuti amalola kuthandauza payekha ndi zonse za zinyalala. Makulidwe okwana zatsalira adzaona kapangidwe tirigu.

Pakuti mortars kugwiritsidwa ntchito ndi sieve fineness modulus wa 1.2. Ngati tikulankhula za simenti, phindu ayenera kukhala wolingana ndi awiri. Pankhaniyi, kapangidwe tirigu konkire ndi Lamulo GOST 10268-80. Sand ntchito pomanga zochokera factionalism. Nthawi zambiri, izo lagawidwa yaikuluikulu. Mbali yoyamba zamitundu ndi tinthu akhoza osiyanasiyana monga 1,25 5, lachiwiri - kuchokera 0,16 kuti 1,25 mm.

The kudalira a kachulukidwe zambiri chinyezi ndi

Natural Sand mwina ndi osalimba zambiri mu osiyanasiyana kuchokera 1300 mpaka 1500 makilogalamu / mamita ^3. Zofunika kusintha buku lake ndi chochuluka kachulukidwe ndi kusintha chinyezi mu osiyanasiyana kuchokera 0 kuti 20%. Ngati chinyezi wokhutira zimasiyanasiyana 3 10%, osalimba kuchepa poyerekeza ndi zomwe ali ndi mchenga wouma. Inde, aliyense grit TACHIMATA ndi wosanjikiza woonda zakuthupi madzi ndi kuwonjezeka buku. Ngati kuwonjezeka chinyezi, madzi adzalowa voids pakati pa mbewu, chimakankhira mpweya. kachulukidwe zambiri mu kuwonjezeka kumeneku latsopano limene tiyenela kuiganizila pamene nkhaniyo mlingo ndi buku.

Features mitundu ikuluikulu ya mchenga

Sand, Standard lomwe linatchulidwa m'nkhani anawagawira ndi chiyambi ndi opangidwa ndi processing. Mwachitsanzo, mtsinje mchenga, ndi yotengedwa mabedi mtsinje, kuti amakhala ndi digiri yapamwamba ya chiyeretso ndipo palibe miyala zosafunika dongo ndi nkhani yachilendo. Ndasambitsa dzenje mchenga opangidwa ku miyala kusamba, chifukwa cha kuchotsedwa fumbi ndi dongo particles.

Seeded mchenga dzenje ncho mu miyala kuti achotse miyala ikulu-kakulidwe inclusions. Ambiri ntchito mu kupanga njira kwa ntchito maziko, zomangamanga ndi kukonzekera pulasitala. Ntchito seeded mchenga kawirikawiri chifukwa cha phula kasakaniza.

Kumanga mchenga ndi zochita kupanga particulate nkhani zomwe aumbike mwa masoka wovulala thanthwe. Amapanga katundu mchenga - osakaniza lotayirira, amene analandira mwa kuphwanya miyala ndi mtundu:

• anajambulapo;
• Miyalayo;
• nsangalabwi;
• slags.

Pachimake mbewu mawonekedwe analandira, ndi pamwamba - akhakula. Nkhanizi ntchito monga filler ndi pa ntchito kupaka pulasitala, pamene pali kufunika kukwaniritsa chogwirika zotsatira kapangidwe kutungira wosanjikiza.

Amapanga mchenga kukhala mbali imodzi ya wosanjikiza aliyense wa pulasitala, ndi factionalism angakhale osiyana, malingana ndi njira ndi zofunika ntchito.

Amapanga mchenga amapangidwa kuchokera slag malasha, ndi processing wa malasha ndi kutenthedwa. Chifukwa cha zimenezi, chuma analandira otsika zili sulfure amene khalidwe kutungira wosanjikiza zimatengera. Pogwira pulasitala ntchito mchenga yokumba limodzi ndi angagwiritsidwe ntchito kupulumutsa chippings, ufa ndi tchipisi za mtundu umenewu.

Pomaliza

Mtengo wa mchenga zimadalira ntchito zake ndi kulankhula ndi m'madera akumidzi miyala ya mowa. Yotsika mtengo zachilengedwe miyala mchenga sichimaperekedwa processing zina. Mmenemo ndi zotupa zazikulu ya dongo ndi matope particles amanena dongo. Nditamaliza processing ukuwonjezeka mchenga mtengo. Seeded mchenga akhoza ndalama zina 2 mtengo kuposa kuloŵedwa m'malo.
