Black chomenyedwa: zotsimikizira luso

Black miyala si nthawi zonse yaiwisi zipangizo zachilengedwe, opangidwa kuchokera ku miyala lolingana mtundu mwa kuphwanya ndi processing wotsatira. Nthawi zina ndi particulate nkhani zomwe TACHIMATA ndi wapadera phula zikuchokera kapena dikira. processing Izi ndi zofunika kupeza mankhwala ndi kukana apamwamba kumva kuwawa ndi guluu wolimba (makhalidwe guluu wolimba ndi nyimbo zina nyumba).

Mitundu ndi ntchito

Malinga GOST wakuda chomenyedwa wachinsinsi ndi kukula kachigawo:

1. 5 mpaka 20 mm - sifting miyala (grit), kuimira dongosolo ambiri abwino-grained.
2. 20 mpaka 40 mm - sing'anga-grained mchenga. The zambiri ntchito yomanga.
3. Kuyambira mamilimita 40 70 - zakuthupi coarse, lomwe pa unsembe nthawi zambiri rasklintsovka (mwala kusokonekera kuchotsa voids).

Black wosweka mwala yokoka mwachindunji 2.9 Nchito T / mamita ^3, kotero ^kuti chimadzera yekha ndi makina lolemera.

Nthawi zambiri nkhaniyi ntchito atagona pavements, makwalala m'matauni ndi mabwalo. Komanso chifukwa anapanga njira phula lona. Pomanga nyumba ndi chapansi kapena chapansi a zipangizo ntchito kumatira.

Nthawi zina zinthu izi zachilendo ntchito mu zokongoletsa m'madera wakunja kwatawuni.

kachulukidwe chochuluka wakuda chomenyedwa ndi 2900 kg.

Ubwino ndi Kuipa

Mwa ubwino wa chuma ndi kupereka:

1. Yafupika akulimbana. N'chifukwa chake muyezo phula ayamba kuchotsa makhalidwe wakuda.
2. Kuchuluka kukameta ubweya kulimbikira zokutira anapanga ndi nkhaniyi.
3. kukana zabwino kutsetsereka.
4. Long alumali moyo.
5. Easy compressibility.
6. Kuthekera stacking kuzizira zakuthupi.

deficiencies Black chomenyedwa zambiri wolemekezeka:

1. Mkulu permeability zipangizo.
2. Nthaŵi yaitali nthawi ya mapangidwe m'misewu (mwezi 1). Ngati nkhaniyo ndi iikidwe pa kutentha pansi pa ziro masika m'munsi adzakhala imbani anakhumba mphamvu ya chaka chimodzi chokha.

Komanso, pamene khazikitsa msewu watsopano zidzakhala zosatheka kuti khama kuthamanga amphamvu kwa masiku 5.

Kuchuluka kwa chuma kumanga kumadalira njira kupanga.

Yopanga luso ndi ozizira

Chotero chomenyedwa wakuda ankangomva zokonzera pavements. ozizira njira zotsimikizira luso m'njira ziwiri: mwachindunji pa malo kapena mu unsembe wapadera thiransipoti wotsatira ku malo a ntchito.

Alikusasanyira zopangira ntchito phula, phula ndi emulsions pa kutentha 100 ⁰ C 200 ⁰ C. The chifukwa zinthu aikidwa mu kuzizira. Pamene chikhalidwe ichi kutero kutentha, kamene sikadzawonetsedwa pansipa +5 ⁰ C.

Cold macadam ndi otsika kukhuthala, kotero kuti akhoza kusungidwa mu zipinda ozizira kwa nthawi yaitali.

Technology wa kupanga njira ofunda

Pankhaniyi, chuma pansi kutenthetsa mankhwala kwa 80 ⁰ C kwa 120 ⁰ C. Izo ntchito atanyamula chomenyedwa ofunda pamalo latsopano msewu ndi katundu wochepa makina. Gwiritsirani ntchito ayenera kukhala pa kutentha 60 ⁰ C 100 ⁰ C.

Yopanga luso otentha njira

Hot wakuda wosweka mwala akupangidwa ku kutentha kwa 120 ⁰ C mpaka 180 ⁰ C. Mankhwala a chuma komanso ntchito phula phula. Ntchito kokha pamene kutentha kwake ndi mkati + 100-120 ⁰ C.

Amaunjika ofunda ndi otentha macadam zofunika yomweyo pambuyo ulimi wake. Choncho nthawi zonse ntchito yapadera zida Phula ogwiritsa pavements.

Mu mapangidwe mafakitale zipangizo zodula ntchito kupanga wakuda chomenyedwa.

Ndi zothandiza kuti zipangizo zopangira opangidwa mchikakamizo cha kutentha, ali ndi kukana otsika kwambiri mapangidwe nkhungu ndi cinoni. Pofuna kuthetsa sangathe uno, mu thanthwe wosweka anawonjezera asidi boric, diethanolamine ndi mafuta asidi kuyimitsidwa.

Kodi odikira?

Kuti apange wakuda wosweka mwala yekha, zigawo zotsatirazi ziyenera osokonezeka:

1. Atavutika (yabwino kwambiri laimu), kalasi M600. Ndi bwino kugwiritsa ntchito chuma kachigawo pakati (20-40 mm), popeza ali katundu wabwino absorbent.
2. Astringent chigawo. Monga izo tikulimbikitsidwa kugwiritsa ntchito phula BND 200/300. Voliyumu ya binder ndi ziyenera kukhala dongosolo la 4-5% ya kulemera okwana miyala.
3. NaOH amadzimadzi njira (thunthu limeneli lidzagwiritsidwa ntchito monga emulsion ndi).
4. mafuta asidi kupanga kuchuluka kwa 3% mwa kulemera kwa phula.
5. chosakanizira magetsi ndi ng'oma peyala woboola pakati.
6. Chipangizo yopezera chuma otentha.

chosakanizira ayenera akhale okonzeka ndi Kutentha mfundo adzapereka kutentha anafuna chithandizo cha makhalidwe.

Nthawi kusakaniza mu chosakanizira cha zigawo zonse mwachindunji zimadalira buku la chakudya ndi kukula kwa chosakanizira cha.

Kugwiritsa wakuda wosweka mwala matailosi akhoza mayendedwe onse pa chigawo wakunja kwatawuni mubale wosanjikiza pamwamba pa malo akhungu panyumba kapena bungwe odalirika ndi cholimba mestodlya magalimoto galimoto yake. Komabe, tiyenera kuganizira kuti pomanga payekha ndi zotheka kugwiritsa ntchito zipangizo zina zimene zosavuta ndi mtengo kuti manja anu popanda kugwiritsa ntchito zinthu magetsi. Kuwonjezera kuika miyala wakuda zovuta kuti yekha.
