Iqhezu 20-40 - inyengane eluthulini: ubunzima bayo, ukuxinana, kunye nezinye iimpawu

Xa enze iintlobo ezininzi ukulungiswa okanye umsebenzi wokwakha ifuna ukusetyenziswa ngelitye. Ukuze ukwazi ukusebenzisa ngenxa ezithile ngeenjongo, eluthulini ilitye yenziwe ezahlukeneyo alwayo. Eziphathekayo ubungakanani obuncinane esetyenziselwa iinjongo zokuhombisa, iqhezu irhabaxa iyafuneka xa kusakhiwa izinto ezibalulekileyo enzima.

I-avareji ubungakanani fraction - 20-40. igranite bamoya yale ubukhulu yeyona ethandwa. Zwi diorite okanye Nyengane asetyenziselwa imveliso yawo.

kuqamba ezibonakalayo

Igranite - uthathwa iliwa kakhulu nzima, nto leyo ifumaneka kwi-langa. Ngenxa ngamandla awodwa, ezenziwe ngezinto lenyengane, kuquka igrabile, ziyasetyenziswa apho kwiziza zokwakha ziza evezwa umsebenzi layisha phezulu. Kwaye ngenxa yokuba iliwa lenyengane yandile phantse onke amazwe, iindleko zokwakha kuyo ifikeleleka nezaziwayo.

izinto Umbala kuxhomekeke koko izimbiwa ziqulathe lenyengane, kodwa ngokuqhelekileyo oko umbala obomvu grey. Emva Ngokudibana imali encinane yezimbiwa eziphathekayo emnyama babe nenkangeleko nezinala.

ezibonakalayo

Iqhezu 20-40 - inyengane eluthulini, egqalwa le lokufaka ilungileyo kwicandelo lokwakha. Ngenxa ukusetyenziswa kwayo kunokwenzeka ngaphandle kobunzima ukuba bazalise iifom ezifanelekileyo, ukonga, yaye kakhulu kunene, ukuhlanganiswa eziphathekayo eninzi. Ekubeni lenyengane wokudla ube uhlobo rough zinqunqwe, adhesion obalaseleyo kwenzeka amacandelo, nto leyo eqinisekisa adhesion ogqwesileyo ingxenye eziphathekayo.

Xa kuthelekiswa nezinye imfuno ubukhulu, kuba ingqolowa avareji eziveliswa kunye neendleko liphantsi yabasebenzi, eqinisekisa iindleko eziphathekayo kakhulu lula.

izakhiwo

Performance kuxhomekeke mihlaba ilandelayo:

1. Iqhezu 20-40 - inyengane eluthulini, eba ukuxhathisa iphezulu kukuwohloka okumbophelela.
2. Le nkcazelo enokumelana kwisiqhoboshi inani ngumkhenkce / nobudlelwane kunye kuzahlula.
3. Ubukho flakiness eliphantsi. Ubunzima iyonke beenkozo bit ezo iimilo tyaba, inaliti kunye lula zilinganisiwe uhlalutye isambuku kwezoyilo kunye mortars.
4. Ukuxinana zelitye lenyengane inkunkuma 20-40 kuxhomekeke hlobo kwenziwe kuzo. Ngokomzekelo, izinto ezincinane zelitye lenyengane cube lulingana malunga 1370-1400 kg yilimestone - 1280, gabbro, diabase - 1440 kg.
5. porosity Small. Ukungabikho phantse epheleleyo pores lula ekwiqondo eliphezulu nezisezantsi Absorption amanzi ingumlingani.
6. yemisebe Low. Le mfanelo ibalulekile kakhulu, kuba ikuvumela ukuba usebenzise zokufunda izakhiwo zokuhlala, zorhwebo, uluntu kunye nezoshishino. Eli nani libandakanya eziguqulweyo, izikolo kunye nezibhedlele.

ukulandelwa GOST

On lenyengane bamoya 20-40 GOST 8267-93 lixela inani ezi zikhombisi zilandelayo:

• 5-23% flakiness;
• kwi ekwakhiweni akufunekanga ibe ngaphezulu kwe-0.5% iinkozo yi-5 mm kwaye ngaphezu kwama-10% of amaqhezu ezincinane kwe-20 mm.
• uthuli lodongwe kufuneka ingadluli 0.3%;
• Imigca 1000-1400 amandla;
• ubunzima 1 m3 zelitye lenyengane eluthulini 20-40 - 1.35 tonnes;
• ubukho izigaqa ngodongwe - kwi ezininzi 0.25%;
• ubukho kwamasuntswana amatye soft - hayi ngaphezulu kwe-5%;
• ubungakanani bulk lexinene malunga 2.7 g / cm ^3;
• Ukunyamezela - Isalathisi I1.
• ipesenti yamanzi nokufunxwa - kutsho kuma-0.4%.

Ukongeza, izinto kufuneka iimpawu zilandelayo:

1. Olubonisa yokumelana iqabaka - F300.
2. imisebe inqanaba kufuneka ingadluli 370 uw / kg.

Ngexesha yokuqingqwa yovavanyo umgangatho lemveliso lwenzeka ezi kunye nezinye iimpawu moto.

scope

igranite odakumbileyo unawo iipropati chemico-physical ezinika yokusebenza cwangciso. nobukhulu bayo ichazwa ubungakanani okuziinkozo.

Iqhezu 20-40 - inyengane eluthulini, nesetyenziswa:

1. Izixazululo eziphathekayo.
2. Ngexesha nokwakhiwa kwezakhiwo ufakelo lwesamente.
3. Ngexesha yokubekwa iziseko.
4. Njengoko loxinano bulk ukuba isiseko phantsi sheet igada.
5. Ukomeleza okanye ngale ndlela.
6. Xa ifowuni iimoto yokupaka.
7. Kuba iindawo yokwexeshana aya kusingatha izixhobo zokwakha.
8. Ngexesha ukwakhiwa kweendlela esiporweni kwezothutho.
9. Lukhuni ubuso phantsi w / e kwingoma.

Iimpawu ukuthenga

Thina Andithethi malunga inkqubo yokufumana kunye ukhetho izinto. Okona kubalulekileyo, izinto ndadibana zonke specs, kwaye oku kungenzeka kuphela ukuba uyahlangabezana neemfuneko GOST. Kodwa ngaba ngokwenene abalulekileyo yeempawu zichazwe kolu xwebhu loluntu? Kwenzeka ntoni xa njengamasuntsu akayi ukuhlangabezana neemfuno angasentla GOST?

Njengoko kuqinisekiswa yi isiko, naluphi na utshintsho kuqulatha kubola. Umzekelo, ukuba iinkozo yeflethi ubunzima bungama ngaphezu efunyenwe ukusebenzisa kwabo umgangatho emiselweyo ngaphantsi eziphathekayo, kwaye isixa somxube eziphathekayo kwakuza kufuneka ukwandisa, kukhokelele ekwandeni iindleko.

Ukuba usityumze igranite 20-40 ubunzima incinane (okanye ngaphezulu) kunokuba kuyimfuneko, ngoko, kumafa yayo, kukho iinkozo ezinye angquzulanayo. Ngenxa yoko, kukokona ubunzima, kokukhona ubunzima lilonke okuziinkozo ecikizekileyo, vice versa: amasuntswana ezinkulu abahlala isithuba esininzi, ukuze loo amaqhekeza kuya zinobunzima obungaphantsi.

Ngoko ke, ukuba uthenge izinto oza kuba iimpawu ezinqwenelekayo, ukuthenga kuyimfuneko ukuqinisekisa ukuba unaso isiqinisekiso, isiphelo sanitary-epidemiological, iimpawu wococeko imveliso kunye yokundwendwela yayo.
