Dub rubble: manufacturing technology

Dub gravel yog tsis ib txwm lub ntuj raw cov ntaub ntawv, ua los ntawm cov pob zeb coj xim los ntawm crushing thiab tom ntej ua. Tej zaum nws yog ib tug particulate khoom uas yog coated nrog ib tug tshwj xeeb bitumen muaj pes tsawg leeg los yog tarry. Qhov no ua yog tsim nyog los tau ib yam khoom nrog ntau dua puas kuj thiab adhesion (adhesion zoo nrog rau lwm cov tsev compositions).

Hom thiab daim ntaub ntawv

Raws li GOST dub rubble txwv kom muab zais los ntawm loj feem:

1. Los ntawm 5 mus rau 20 mm - sifting gravel (zeb), uas nruab nrab yog cov feem ntau zoo-grained qauv.
2. Los ntawm 20 mus rau 40 mm - medium-grained gravel. Cov feem ntau siv nyob rau hauv kev tsim kho.
3. Los ntawm 40 rau 70 mm - lub ntxhib khoom, uas thaum lub sij hawm installation yog feem ntau ua rasklintsovka (pob zeb redistribution kom tshem tawm voids).

Dub crushed pob zeb tej lub ntiajteb txawj nqus yog 2.9 t / m ^3, yog li ^ntawd nws yog thauj xwb los hnyav machine.

Feem ntau cov feem ntau cov khoom no yog siv rau tso Pavements, nroog alleys thiab squares. Tsis tas li ntawd vim hais tias nws ua txoj kev asphalt canvas. Thaum lub sij hawm tsim kho ntawm lub tsev nrog ib tug hauv qab daus los yog ib tug hauv qab daus ntawm raw cov ntaub ntawv siv rau waterproofing.

Tej zaum qhov no txawv txawv cov ntaub ntawv uas siv nyob rau hauv lub decorations ntawm suburban cheeb tsam.

Tej kev ceev ntawm dub rubble yog 2900 kg.

Zoo thiab tsis zoo

Cov qhov zoo ntawm cov khoom no yog muab:

1. Txo cracking. Uas yog vim li cas rau tus txheej txheem asphalt yog nce hloov cov dub rubble.
2. Nce shear kuj coatings ua nrog no cov ntaub ntawv uas.
3. Zoo kuj mus zawv zawg.
4. Ntev txee lub neej.
5. Ib qho yooj yim compressibility.
6. Tseem stacking cov khoom txias.

Dub rubble raug feem ntau distinguished:

1. High permeability cov ntaub ntawv.
2. Ntev heev ib lub sij hawm ntawm tsim ntawm lub pavement (nce txog li 1 lub hlis). Yog hais tias cov ntaub ntawv uas yog yuav tsum tau muab tso nyob rau hauv kub hauv qab no zero nyob rau hauv lig lub caij nplooj zeeg, lub hauv paus yuav hu yam lub zog ntawm tsuas yog ib xyoo.

Tsis tas li ntawd, thaum txhim kho tshiab pavement nws yuav tsis yooj yim sua rau pheev muaj zog siab kom mus txog rau 5 hnub.

Scope ntawm kev tsim kho cov ntaub ntawv uas nyob lom zem ntau nyob rau hauv txoj kev ntawm kev siv thiab ua.

Qhuav technology los ntawm tus mob khaub thuas

Tej dub rubble tsuas yog siv rau kho Pavements. txias txoj kev raug technology nyob rau hauv ob txoj kev: ncaj qha rau ntawm qhov chaw los yog nyob rau hauv ib tug tshwj xeeb installation tom tsheb thauj mus los rau ntawm qhov chaw ua hauj lwm.

Npaj ib raw khoom siv ib, bitumen thiab emulsions ntawm ib tug kub ntawm los ntawm 100 ⁰ C rau 200 ⁰ C. Cov ua cov ntaub ntawv uas yog muab tso rau hauv lub txias. Thaum zoo li no tsim nyog mob yog qhov kub thiab txias, uas yuav tsum tsis txhob yuav hauv qab no +5 ⁰ C.

Khaub thuas macadam yog ib tug tsis tshua muaj viscosity, yog li ntawd nws yuav tsum muab cia rau hauv txias chav rau ib ntev lub sij hawm.

Technology ntawm zus tau tej cov sov txoj kev

Nyob rau hauv cov ntaub ntawv no, cov ntaub ntawv uas yog raug los ua cua sov kev kho mob los ntawm 80 ⁰ C mus rau 120 ⁰ C. Nws yog siv rau packing rubble sov tshiab txoj kev chaw nrog ib tug tsawg txhua yam load. Siv cov ntaub ntawv uas yuav tsum muaj ib tug kub ntawm 60 ⁰ C 100 ⁰ C.

Qhuav technology kub txoj kev

Kub dub crushed pob zeb ua ntawm kub ntawm 120 ⁰ C mus rau 180 ⁰ C. Rau kev kho mob ntawm cov khoom yog kuj thov ib thiab bitumen. Siv nws tsuas yog thaum nws kub yog tsis pub dhau + 100-120 ⁰ C.

Pawg sov thiab kub macadam tsim nyog tam sim ntawd tom qab nws lawm. Nws yog yog li ntawd ib txwm siv tshwj xeeb cov khoom Asphalt mounting Pavements.

Nyob rau hauv tej kev kawm muaj lub kim cov khoom siv rau qhov siv thiab ua dub rubble.

Nws tseem yog nqi xav tias cov raw cov ntaub ntawv ua nyob rau hauv tus ntawm siab kub, muaj ib tug heev tsawg kuj mus rau tsim ntawm puab thiab pwm. Nyob rau hauv thiaj li yuav tshem tawm qhov disadvantage, nyob rau hauv lub crushed pob zeb ntxiv boric acid, diethanolamine thiab cov fatty acid ncua kev kawm ntawv.

Yuav ua li cas npaj koj tus kheej?

Yuav kom tsim dub crushed pob zeb nyob ib leeg, lub nram qab no Cheebtsam yuav tsum tau tov:

1. Crushed (feem ntau haum limestone), qib M600. Nws yog zoo dua rau siv cov khoom ntawm nruab nrab feem (20-40 hli), vim nws muaj zoo ntxeem tau dej zog.
2. Astringent tivthaiv. Raws li nws yog pom zoo kom siv bitumen BND 200/300. Lub volume ntawm lub phau ntawv yuav tsum muaj qhov kev txiav txim ntawm 4-5% ntawm tag nrho cov luj ntawm gravel.
3. NaOH aqueous tov (qhov no tshuaj yuav siv tau raws li ib tug emulsion).
4. Synthetic fatty acid nyob rau hauv tus nqi ntawm cov 3% los ntawm luj ntawm bitumen.
5. Electric tov khoom nrog ib tug txiv moj coos zoo li tus nruas.
6. Ntaus rau extracting kub khoom.

Lub tov khoom yuav tsum muab nruab nrog ib tug caij cua kub uas yuav muab cov kev kawm kub kev kho mob ntawm rubble.

Lub nws lub sij hawm nyob rau hauv tus tov khoom ntawm tag nrho cov Cheebtsam ncaj qha nyob rau hauv lub ntim ntawm pub thiab luaj li cas ntawm tus tov khoom.

Siv dub crushed pob zeb pobzeb tau tag nrho cov kev rau ib tug suburban seem, tsim rau sab saum toj txheej ntawm lub qhov muag tsis pom thaj chaw nyob ib ncig ntawm lub tsev los yog npaj txhim khu kev qha thiab check mestodlya chaw nres tsheb nws lub tsheb. Txawm li cas los, nws yuav tsum coj mus rau hauv tus account uas nyob rau hauv lub private siv yog tau siv lwm yam ntaub ntawv, uas yog npaum li cas yooj yim thiab pheej yig dua yuav ua rau koj tus kheej ob txhais tes tsis muaj kev siv ntawm cov cua kub hais. Dhau li tso cov dub gravel nws yog heev yooj yim mus ua ib leeg.
