Black rubble: n'ichepụta technology

Black gravel bụghị mgbe niile eke ngwaọrụ, na-emepụta si nkume kwekọrọ ekwekọ agba site ndinuak na ụdi nhazi. Mgbe ụfọdụ, ọ bụ a particulate ihe onwunwe nke na-ntekwasa na a pụrụ iche bitumen mejupụtara ma ọ nọdu. Nke a nhazi dị mkpa iji nweta a ngwaahịa na elu abrasion eguzogide ma na adhesion (adhesion àgwà na ndị ọzọ na ụlọ ikwọ).

Na ụdị na-ngwa

Dị ka GOST black rubble nkewa site size nta:

1. Si 5 na 20 mm - sifting gravel (grit), nke na-anọchite anya ndị kasị mma-grained Ọdịdị.
2. Site 20 ruo 40 mm - ajụ-grained gravel. Ndị akacha eji na-ewu.
3. Site na 40 ruo 70 mm - akparị ihe, nke n'oge echichi na-emekarị rụrụ rasklintsovka (nkume redistribution wepụ voids).

Black gburu nkume kpọmkwem ike ndọda bụ 2.9 t / m ^3, nke mere ^na ọ na-ebu naanị oké ígwè ọrụ.

Ọtụtụ mgbe a na ihe onwunwe na-eji maka na-ebikwasị pavements, n'obodo ukwu alleys na n'ámá. N'ihi na ọ na mere n'okporo ụzọ korota kwaaji. N'oge ndị na-ewu ụlọ na a na okpuru ulo ma ọ bụ a na okpuru ulo nke ngwaọrụ eji maka waterproofing.

Mgbe ụfọdụ, a pụrụ iche ihe na-eji na decorations nke suburban ebe.

Nnukwu njupụta nke nwa rubble bụ 2900 n'arọ.

Uru na ụkọ ihe ụfọdụ

N'etiti uru nke ihe onwunwe bụ inye:

1. Belata cracking. Ọ bụ ya mere ọkọlọtọ korota na-esiwanye dochie black rubble.
2. Mụbara shiee eguzogide coatings mere na ihe a.
3. Good iguzogide eji.
4. Long adị ndụ.
5. Easy compressibility.
6. Ekwe omume nke stacking ihe oyi.

Black rubble erughị eru na-emekarị na-akwanyere ùgwù:

1. High permeability ihe.
2. Ogologo oge nke guzobe nke pavement (ruo 1 nke ọnwa). Ọ bụrụ na ihe a ga-tọrọ na okpomọkụ n'okpuru efu ke mbubreyo n'oge mgbụsị akwụkwọ, ndị isi ga ọsịsọ chọrọ ike nke naanị otu afọ.

Ọzọkwa, mgbe wụnye ọhụrụ pavement ọ ga-ekwe omume na-akpa ike ọnọdụ maka ruo 5 ụbọchị.

Akporo nke ewu ihe na-adabere n'ụzọ dị ukwuu na usoro nke rụpụta.

Production technology site oyi

Dị otú ahụ nwa rubble na-eji maka idozi pavements. oyi na-atụ usoro n'ichepụta technology na ụzọ abụọ: na na saịtị ma ọ bụ na a pụrụ iche echichi na ụdi njem na n'ebe ọrụ.

Akwadebe a akụrụngwa na iji tar, bitumen na emulsions na okpomọkụ nke si na 100 ⁰ C 200 ⁰ C. Ihe onwunwe na-enịm ke oyi. Mgbe a dị mkpa ọnọdụ bụ okpomọkụ, nke agaghi-n'okpuru +5 ⁰ C.

Oyi macadam bụ a ala viscosity, nke mere na ọ nwere ike ịchekwa oyi ụlọ a ogologo oge.

Technology nke mmepụta nke na-ekpo ọkụ usoro

Na nke a, ihe na-akwagide ikpo omume si na 80 ⁰ C 120 ⁰ C. Ọ na-eji maka mbukota rubble ọkụ ụzọ ọhụrụ na-ebupụta na a ala n'ibu ibu. Iji ihe onwunwe ga-abụ na a okpomọkụ nke 60 ⁰ C 100 ⁰ C.

Production technology na-ekpo ọkụ usoro

Hot black gburu nkume emepụta na okpomọkụ si na 120 ⁰ C 180 ⁰ C. N'ihi na ọgwụgwọ nke ihe a na-etinyere tar na bitumen. Jiri naanị mgbe ya okpomọkụ bụ n'ime + 100-120 ⁰ C.

Tojupụtara-ekpo ọkụ na-ekpo ọkụ macadam mkpa ozugbo ya mmepụta. Ọ bụ ya mere mgbe niile na-eji nkà na ngwá Asphalt arịọnụ pavements.

Na ulo oru gburugburu nke oké ọnụ akụrụngwa na-eji maka imewe nke nwa rubble.

Ọ bụkwa uru na-ewere na ndị ngwaọrụ emepụta n'okpuru nduzi nke okpomọkụ, nwere a nnọọ ala iguzogide guzobe ebu na ebù. Iji wepụ a mwepu, na-echi ọnụ n'ala nkume na kwukwara boric acid, diethanolamine na abụba acid nkwusioru.

Olee otú iji kwadebe onwe gị?

Iji mepụta nwa gburu nkume naanị, ndị na-esonụ components ga-agwakọta:

1. Mwute (kacha adabara na nkume nzu), ọkwa M600. Ọ dị mma na-eji ihe onwunwe nke etiti nta (20-40 mm), ebe ọ bụ na e nwere ezigbo absorbent Njirimara.
2. Astringent akụrụngwa. Dị ka ọ na-atụ aro iji bitumen BND 200/300. Olu nke na nragide kwesịrị nke iji nke 4-5% nke ngụkọta nke ịdị arọ nke gravel.
3. NaOH okenye ihe ngwọta (a umi ga-eji dị ka ihe emulsion).
4. Sịntetik ọdụdụ acid na ego nke 3% site arọ nke bitumen.
5. Electric igwekota na a ube ekara drum.
6. Ngwaọrụ maka adịrị ekpo ọkụ ihe.

The igwekota ga-onwem na a kpo oku mmewere na ga-chọrọ okpomọkụ maka ọgwụgwọ nke rubble.
