Black inkunkuma: ubuchwepheshe lemveliso

Black igrabile alusoloko izinto zendalo ekrwada, eyenziwe ngamatye esihambelanayo umbala ngokukhanywa nokulungiswa elandelayo. Maxa wambi iba izinto ezithile apho isale sisincoko ngebhitumene ekhethekileyo okanye ukulibala. Le nkqubo luyimfuneko ukuze ufumane imveliso kunye ukuxhathisa aphezulu lingonakali kunye adhesion (iimpawu adhesion kunye nezinye ezaqanjwa isakhiwo).

Types and izicelo

Ngokutsho GOST inkunkuma emnyama zihlelwa ubungakanani iqhezu:

1. Ukususela-5 ukuya kwi-20 mm - bazama uhlalutye (uhlalutye), nto leyo imele isakhiwo kakhulu entle-olungisiweyo.
2. Ukususela 20 ukuya kuma-40 mm - eliphakathi-olungisiweyo luhlalu. Eyona ezininzi eziqhele ukusetyenziswa ekwakheni.
3. Ukususela mm 40 ukuya 70 - umbandela, izinto ngexesha lofakelo yenziwa rasklintsovka (ngokutsha ilitye ukususa imigodi).

Black bamoya ilitye womxhuzulane ezithile yi 2.9 t / m ^{3, ukuze} ihanjiswa kuphela oomatshini enzima.

Amaninzi le nto lisetyenziswa kwi iyabala iipavumente, iindawo zasezidolophini kunye nezikwere. Kwakhona kuba wenza indlela yemizobo igada. Ngexesha ukwakhiwa kwezindlu kunye kwesakhiwo okanye elingaphantsi zempahla ekrwada esetyenziselwa amanzi.

Ngamanye amaxesha le nto ingaqhelekanga ezisetyenziswa imihombiso lweendawo zokuhlala ezisezidolophini.

ingxinano Bulk imfucuza elimnyama 2900 kg.

Ubuhle lobubi

Phakathi eziluncedo yale ncwadana kukunika:

1. nokuqhekeka Ukuncipha. Kungenxa yoko le nto asphalt standard beqhubeka indawo inkunkuma emnyama.
2. Ukwanda ukumelana uchebe of Ipeyinti eyenziwe nale nto.
3. enokumelana okuhle sliding.
4. ezikhabhathini Long.
5. compressibility Easy.
6. Ithuba ingqokelela nengqele eziphathekayo.

zintswelo inkunkuma Black ngokuqhelekileyo avelele:

1. izinto permeability High.
2. elide kakhulu ngexesha lokusekwa egangathiweyo (ukuya kwinyanga 1). Ukuba into oyifundayo zibekwe kwiqondo lobushushu ngezantsi zero e kokwindla, isiseko kuya ukudayala amandla ezinqwenelekayo konyaka omnye kuphela.

Kwakhona, xa kufakwa yabahambi entsha kuya kuba nzima ukufaka uxinzelelo esinamandla kangangeentsuku ukuya ku-5.

Umda kwemathiriyeli yokwakha kuxhomekeke kakhulu indlela ngawo.

technology Production ukubanda

Ezo inkunkuma emnyama esetyenziselwa kuphela zokulungisa zepavimente. indlela ebandayo lemveliso iteknoloji ngeendlela ezimbini: ngqo kwi sayithi okanye kufakelo olukhethekileyo ngokuhanjiswa emva kwindawo yomsebenzi.

Ukulungiselela i impahla ekrwada usebenzisa tar, itha kunye emulsions kwi lobushushu ukususela 100 ⁰ C kwi-200 ⁰ C. The zezinto ezithile eziziphumo ibekwa kule ngqele. Xa le meko kuyimfuneko ubushushu, akayi kuba yeyiphi ngaphantsi +5 ⁰ C.

macadam Cold i viscosity phantsi, ukwenzela ukuba igcinwe kumagumbi abandayo ixesha elide.

Technology zokukhokhela indlela efudumeleyo

Kulo mzekelo, izinto ufakwa ukufudumeza unyango ukusuka 80 ⁰ C ukuya kwi-120 ⁰ C. Isetyenziswa ukupakisha inkunkuma efudumeleyo imiphezulu indlela ezintsha kunye umthwalo mechanical ephantsi. Sebenzisa izinto mayibe lobushushu 60 ⁰ C ukuya kwi-100 ⁰ C.

technology Production indlela eshushu

black Hot ilitye otyunyuziweyo eziveliswa kwiqondo lobushushu ukususela 120 ⁰ C ukuya 180 ⁰ C. Kuba unyango zokufunda kwakhona isicelo tar kunye ngetha. Sebenzisa kuphela xa ubushushu balo ngaphakathi + 100-120 ⁰ C.

Beka macadam olufudumeleyo eshushu kuyimfuneko ngoko nangoko emva imveliso yawo. Ngoko ke kusoloko kusetyenziswa ezizodwa izixhobo leTela engathethekiyo zepavimente.

Xa iimeko industrial izixhobo ezixabisa esetyenziselwa ukwenziwa yimiwewe emnyama.

Kananjalo kubalulekile ukuba ucinga ukuba izinto awo phantsi kweempembelelo amaqondo obushushu aphezulu, siyakwazi ukumelana ephantsi kakhulu ukuyilwa sande nangesihumba. Ukwenzela ukuphelisa le nokubi, engxondorheni otyunyuziweyo idityaniswe boric acid, diethanolamine kunye nokumiswa okunamafutha acid.

Indlela ukuba uzilungiselele?

Ukuze kuveliswe elimnyama nakhandiweyo yedwa, ezi ndima zilandelayo kufuneka ugalelwe:

1. Ekhathazekile (lekalika ifanelekileyo), kwibakala M600. Kungcono usebenzise nesixhobo iqhezu eliphakathi (20-40 mm), ekubeni kube iipropati elungileyo izifunxi.
2. ingxenye Astringent. Njengokuba kubhaliwe kucetyiswa ukuba usebenzise ngetha nerd 200/300. Umthamo we Umatshini kufuneka zomyalelo 4-5% ye ubunzima lilonke luhlalu.
3. isisombululo NaOH zolwelo (le nto iza kusetyenziswa emulsion).
4. Synthetic ngamanqatha acid kwi mali ka-3% ngokobunzima yebhitumene.
5. Umxhubi zombane kunye kwigubu eliphakathi kwe-ezimile.
6. Isixhobo for nokukha impahla eshushu.

Le Umxhubi kufuneka mayixhotyiswe element ukufudumeza eya kubonelela obushushu ezinqwenelekayo unyango kuyo ngasese.

Ixesha ukuzihlanganisa mixer onke amacandelo ixhomekeke ngqo kwi umthamo omxhesho ubukhulu lokuxhuba.

Ukusebenzisa tile elimnyama zawanqwamza ingoma kwi icandelo ipoma unako, ukuvelisa umaleko phezulu kummandla eyimfama zijikeleze indlu okanye ulungise ethembekileyo elide mestodlya yokupaka isithuthi sakhe. Nakuba kunjalo, kufuneka luthathele ingqalelo ukuba ukwakhiwa zabucala kunokwenzeka ukuba ukusebenzisa ezinye izinto, nto leyo lula yaye kungabinandleko ukwenza izandla zakho ngaphandle kokusebenzisa zokufudumeza lweziqalelo. Ngaphandle ekubekeni njengamasuntsu black kunzima kakhulu ukwenza yedwa.
