Tom ntej: Bitumen MC30
Bitumen MC30 yog ib hom bitumen uas kho tau nruab nrab (MC), ib hom asphalt ua kua uas tsim los ntawm kev sib xyaw cov bitumen uas nkag mus rau hauv dej nrog cov roj av uas muaj roj av, feem ntau yog kerosene. Cov tshuaj no txo ​​cov viscosity ntawm bitumen, ua rau nws yooj yim dua rau kev siv ntawm qhov kub thiab txias yam tsis muaj cua sov ntau dhau. Thaum siv, cov tshuaj no yuav yaj, tawm hauv qab cov bitumen uas ruaj khov uas lo rau ntawm cov nto. Paub txog nws qhov viscosity qis thiab kev ua tau ntau yam, Bitumen MC30 yog siv dav hauv kev tsim kho thiab kev saib xyuas txoj kev thoob ntiaj teb. Rau cov ntawv thov uas xav tau kev ruaj khov thiab tiv taus cua sov ntau dua, Bitumen muaj 115/15 tuaj yeem siv ua ke nrog MC30 los txhim kho kev ua tau zoo hauv kev tsim kho vaj tse thiab cov haujlwm lag luam uas xav tau ntau.
Qhov twg siv Bitumen MC30?
peb Tom ntej: Bitumen MC30 yog zoo tagnrho rau kev tsim kho thiab kev saib xyuas pavement, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas xav tau kev hloov pauv, siv cov tshuaj txias txias. Nws ua tau zoo hauv kev npaj qhov chaw rau asphalt overlays thiab tiv thaiv cov txheej txheem hauv qab. Cov xwm txheej siv feem ntau suav nrog:
- Prime Coats: Siv rau unbound granular bases (piv txwv li, gravel los yog crushed pob zeb) los txhim kho adhesion nrog tom qab asphalt txheej.
- Tack Coats: Siv cov txheej txheem pavement uas twb muaj lawm los xyuas kom muaj kev sib raug zoo nrog cov asphalt tshiab.
- Surface Treatments: Tiv thaiv thiab kaw cov chaw ntawm txoj kev, tiv thaiv kev nkag mus rau hauv dej thiab txuas ntxiv txoj kev pavement.
- Txias Mix Asphalt: Tsim nyog rau kev kho lossis paving hauv cov huab cua txias uas qhov kub sib xyaw asphalt tsis zoo.
Nws cov khoom nruab nrab-kho tau ua rau nws muaj txiaj ntsig tshwj xeeb hauv thaj chaw kub thiab txias, ntsuas qhov nkag mus thiab kho lub sijhawm rau kev ua haujlwm zoo.
Daim ntawv thov ntawm Bitumen MC30
MC30's tsawg viscosity thiab yooj yim ntawm kev siv ua rau nws mus rau cov khoom siv rau ntau yam kev siv:
- Prime Coat Application: Txau mus rau hauv lub hauv paus npaj ntawm tus nqi ntawm 0.7-1.2 litres ib square meter, Bitumen MC30 nkag mus rau saum npoo, waterproofs nws, thiab khi cov khoom xoob. Qhov no tsim lub hauv paus ruaj khov rau asphalt txheej.
- Tack Coat Application: Siv rau ntawm tus nqi sib dua (ib puag ncig 0.2-0.5 litres ib square meter), nws ua raws li cov nplaum ntawm cov txheej txheej pavement, ua kom muaj cov qauv monolithic uas tiv taus kev nplua thiab delamination.
- Nto Txheej: Siv los kaw cov kab nrib pleb me me thiab tiv thaiv huab cua, ua kom lub neej ntev ntawm txoj kev.
- Ntoj Nroj Tsuag: Zoo meej rau kev sib txawv lossis patching thaum kho txoj kev, tshwj xeeb tshaj yog thaum huab cua txias.
Tsis muaj cua sov feem ntau yuav tsum tau nyob rau hauv qhov chaw sov, txawm tias qhov sov me ntsis tuaj yeem txhim kho kev nkag mus rau hauv cov huab cua txias. Ib txwm ua raws li cov qauv hauv zos engineering kom tau txais txiaj ntsig zoo tshaj plaws.
Packing ntawm Bitumen MC30
Nws tau ntim rau kev thauj mus los nyab xeeb thiab khaws cia:
- Steel Drums: Feem ntau ntim rau hauv cov tshiab, tuab steel nruas (kwv yees li 220 kg txhua) mounted rau ntawm pallets los tiv thaiv cov xau thaum xa khoom. Lub thawv txheem 20-tuj tuaj yeem tuav ib ncig ntawm 80 nruas.
- Kev xaiv ntau: Muaj nyob rau hauv bitutainers lossis tankers rau cov haujlwm loj, kom ntseeg tau tias xa mus rau qhov chaw tsim kho. Kev lees paub zoo yog qhov tseem ceeb - cov neeg muag khoom muaj npe nrov ua cov kev sim batch thiab npaj kev soj ntsuam thoob ntiaj teb kom ua tau raws li cov qauv zoo li ASTM D2027M-13 lossis EN 15322: 2009.
Tack Coat vs. Prime Coat: Yuav Ua Li Cas Bitumen MC30 Fits Hauv
- Prime Coat: Bitumen MC30 ci ntsa iab raws li lub tsho tiv no, nkag mus rau hauv cov pob zeb kom txhawb nqa adhesion nrog thawj txheej asphalt. Nws tau thov ntawm tus nqi siab dua thiab yuav tsum tau kho lub sijhawm ua ntej paving.
- Tack Coat: Raws li a tack tsho, nws yog siv ntau sparingly rau daim ntawv cog lus uas twb muaj lawm asphalt nto nrog tshiab overlays. Nws ceev adhesion zog ua kom lub seamless pavement qauv. Hauv ob qho tib si, Bitumen MC30 txhim khu kev ruaj ntseg, txo cov nqi tu, thiab txhim kho txoj kev ua haujlwm.
Vim li cas thiaj xaiv Bitumen MC30?
Solvent puag asphalt muab cov nqi tsim nyog, txhim khu kev qha rau txoj kev ua haujlwm. Nws txoj kev yooj yim ntawm kev thov, muaj peev xwm sib koom ua ke, thiab hloov tau mus rau ntau qhov kev nyab xeeb ua rau nws yog ib qho tseem ceeb hauv kev lag luam. Txawm hais tias koj tab tom priming lub hauv paus, tacking pavement txheej, los yog sealing nto, Bitumen MC30 muab cov txiaj ntsig kav ntev.
