Crushed pob zeb yog tsim los ntawm kev sib tsoo cov tsev thiab cov qauv, xws li cib, pob zeb thiab asph alt. Tom qab ntawd muaj kev sib tsoo rau hauv feem thiab ua kom huv los ntawm cov khib nyiab tsis tsim nyog, cov hlau thiab cov khoom txawv teb chaws. Lub ntsiab zoo ntawm cov khoom siv hauv tsev no yog tus nqi qis thiab ntau yam kev siv. Tsis tas li ntawd, lub pob zeb crushed no yog ib txoj hauv kev zoo los pov tseg cov khoom siv pov tseg thiab rov siv dua. Kab lus no yuav muab cov ntaub ntawv hais txog cov khoom tseem ceeb ntawm cov khoom siv no thiab nws cov ntawv thov. Tsis tas li ntawm no koj tuaj yeem saib lub pob zeb thib ob, cov duab tau nthuav tawm.
Basic properties of crushed pob zeb
Recycled crushed pob zeb yog cov khoom tsim los ntawm kev sib tsoo thiab crushing qhob slabs, tsev, cib thiab asph alt. Nws cov yam ntxwv tseem ceeb yog:
- nqi qis. Tus nqi ntawm cov pob zeb no yuav luag 2lub sij hawm tsawg, nws yog ntuj;
- multifunctionality;
- loj scope;
- nce dej tiv taus.
Lwm yam zoo ntawm cov pob zeb crushed, xws li lub zog, Frost tsis kam, durability, yog me ntsis qis dua cov natural. Txawm li cas los xij, vim muaj peev xwm thiab siv tau hauv cov cheeb tsam raug thiab vim tus nqi qis, cov khoom no tsis yog qhov tseem ceeb. Cov pob zeb crushed tshaj plaws yog qhov thib ob nrog qhov tsis sib xws, nrog qhov loj txog li 6 cm lossis 60 mm. Txawm li cas los xij, cov khoom sib cais nrog feem ntawm 2 mus rau 4 cm, 4 mus rau 7 cm thiab 7 txog 10 cm yog nrov heev.
Crushed Secondary. Daim ntawv thov
Vim nws tus nqi qis, kev ua haujlwm thib ob crushed pob zeb yog siv rau cov laj thawj hauv qab no:
- npaj lub hauv paus rau lub hauv paus ntawm cov tsev thiab cov plag tsev;
- as aggregate for concrete;
- rau kev tsim cov pob zeb thiab cov pob zeb ntxiv;
- rau rov qab thaum npaj kev taug kev thiab rau txoj hauv kev npaj rau kev tso paving slabs;
- hauv kev tsim kho ntawm txoj kev ib ntus thiab av, thaum tus nqi yog qhov tseem ceeb tshaj qhov zoo;
- rau kev sau hauv qab chaw nres tsheb thiab chaw pav rau ntau lub hom phiaj;
- yog hloov av thaum rov qab;
- kev sib ntaus sib tua;
- ua lub hauv paus rau cov qauv dej;
- rau hmoov txoj kev thiab kev taug kev thaum dej khov. Nws siv cov crumbs zoo nrog ib feem ntawm txog li 10 hli;
- rau kev kho kom zoo nkauj kho kom zoo nkauj.
Crushed Secondary. Tus nqi rau cov tuam txhab tsim kho
Nyob rau hauv lub siab xav ntawm cov neeg ua lag luam kom txo tus nqi ntawm kev tsim khoom, hom pob zeb crushed no pab tau zoo heev. Cov khoom siv no ua rau nws tuaj yeem txo tus nqi thaum tswj kom zoo. Nws yog lwm txoj hauv kev zoo rau cov ntaub ntawv uas muaj nqi siab thiab txo tus nqi ntawm cov qauv.
Txhawb nqa ib puag ncig
Ua tsaug rau kev pov tseg ntawm kev tsim kho pov tseg thiab tsim cov khoom siv thib ob los ntawm nws, uas yog tom qab siv kev nyab xeeb, tsis yog tsuas yog tus nqi ntawm cov qauv tau los ntawm nws tau txo qis, tab sis lub teb chaws ecology tseem khaws cia thiab txhawb nqa. Yog li ntawd, nyob rau hauv lub ntiaj teb no niaj hnub no, overproduction ntawm tej yam uas tsis yog-metallic tsev cov ntaub ntawv los ntawm cov khoom pov tseg yog nce.
