Phula phula. Zopangidwa ndi katundu phula

mitundu yonse ya phula ntchito kulimbitsa roadbed, zigwirizana makamaka a zigawo ziwiri: phula ndi akaphatikiza mchere. yotsirizira wapangidwa malinga ndi mfundo GOST 9128 ku zakuthupi cholimba kwambiri. Phula phula angagwiritsidwe ntchito zopangidwa osiyana.

Features umisiri

phula Natural zambiri zimachitika pafupi minda mafuta mu mawonekedwe a magalasi. Komabe, makampani ndi kumanga msewu ndi zambiri ntchito Baibulo lachiwiri la nkhaniyi - yokumba. Pangani phula kuchokera mankhwala mafuta. Kawirikawiri izi phula akupanga ndi zosungunulira-woyengedwa mafuta.

The zikuchokera phula ndi mitundu yake

The zikuchokera osakaniza wopita amaika mumsewu msewu, kuwonjezera phula zikuphatikizapo zigawo zikuluzikulu monga mchenga ndi miyala. Ntchito yoyamba chopangidwa mchenga phula. Nthawi zina osakaniza ndi kuwonjezera mchere ufa ndi makhalidwe. Umenewu ndi mtundu sizachilendo Kuphunzira. Zimenezi zimatchedwa phula wosweka mwala. Komanso nkhaniyi njira zina pogwiritsa ntchito miyala. osakaniza Pankhaniyi anali anawonjezera kuti chomenyedwa ndi ufa mchere. Phula mitundu iyi akutchedwa miyala.

Malinga ndi cholinga cha kusakaniza chiŵerengero cha zigawo izi zosiyanasiyana. Choncho, chifukwa mlathowu ntchito phula chopangidwa ntchito mchenga chabwino ndi miyala. M'munsi wosanjikiza carriageway pa Nthawi zambiri osakaniza zikuchokera yosiyaniranapo. Pankhaniyi, phula anapangana ndi ntchito chabe chomenyedwa lalikulu kwambiri. Wosanjikiza chapamwamba unatsanuliridwa pa misewu yosalala phula. Pamafunikanso ndalama chomenyedwa.

Mark phula phula

Choncho, mtundu wa filler ntchito umakhudza mphamvu ya mtundu uwu wa zinthu, ndipo chotero, ntchito m'munda wake. Komabe, zikuchokera phula ndi ubwino wake chimodzimodzi amadalira mtundu podmeshennogo iye phula. Kwa kupanga zosakaniza wa mtundu uwu chotchuka ntchito zinthu ngati zimenezi makamaka. Izo lotchedwa phula msewu ndi ikusonyezedwa ndi zilembo BND. The chizindikiro chachikulu chimene chuma zimagawidwa ndi kutentha.

Akamaziwononga, popanda yekha, kuyamba kusungunuka phula. Malingana ngati, kodi mfundo izo zimachitika, nkhani angagwiritsidwe ntchito ina yapadera dera la dziko. Pofuna kudziwa zimene zinthu inu mungagwiritse ntchito phula makamaka phula kaye yang'anani pa wake. Pano mu mawerengero ake kusonyeza osiyanasiyana kukhuthala nkhaniyo. Panopa, ulimi wa phula ntchito mitundu yonse asanu phula msewu BND 40/60, 60/90, 90/130, 130/200, 200/300. The motentha nyengo, nkhani zambiri viscous kuchitidwa mu ulimi wa amaika mumsewu.

Kumene, phula mu phula ayenera kupezeka wambiri chokwanira. Mochuluka nkhaniyi mu yokonza zosakaniza si ambiri ntchito. Mbali otentha a amaika mumsewu ayenera anamwazikana ndipo si limodzi. Komabe, ngati sikokwanira phula mu phula kenako kuyamba kuchitika onse njira akumane. Iwo likulowerera madzi komanso m'nthawi yozizira, kuukhadzula.

The katundu yaikulu ya BND

Kupatula kukhuthala phula phula amakhala ndi katundu monga:

• Ductility. chiwerengerochi anatsimikiza ndi mtunda limene phula akhoza ija ulusi popanda chotupa ake. Kusiyana ndi, ndi apamwamba a adhesiveness wa kusakaniza. Road bitumens ambiri amakhala ndi ductility kuposa masentimita 40 Zofunika pa chizindikiro ichi kwa BND upatsidwa 0 digiri C..

• Mapindikidwe makhalidwe. Kudziwa woyenerera wa phula phula kupanga powasamalira katundu monga elasticity, ingayambe, ductility, brittleness, ndi zina zotero D.. Iwo kudziwa mapindikidwe makhalidwe zakuthupi. Pa Kutentha ndi phula yamasika sayenera zimasiyana kwambiri.

Madzi formulations zomangamanga

Phula phula ambiri ali ndi digiri yapamwamba kwambiri kukhuthala. Komabe, nthawi zina amagwiritsidwa ntchito pamene kuthira zokutira ndi mitundu madzi a nkhaniyi. Ntchito makamaka kutalika nyengo ya ntchito msewu. Phula laphalaphala mu kufanana yeniyeni anawonjezera kuti viscous. Chifukwa, ❖ kuyanika pa kutentha m'munsi Kodi musaumitse patalipatali. phula madzi opangidwa ndi Kuwonjezera tuzigawo twa viscous distillate.

Pamene anakonza mpandawo amagwiritsidwanso ntchito sing'anga kukhuthala zakuthupi. Izo ntchito mankhwala a kale chitakonzedwa mapu. Mlingo wa ntchito phula atagona phula mu nkhani iyi si waukulu kwambiri ndipo ndi 0.5 okha L / ^m2.

Kodi zina zikhoza kupezeka mu BND

Kupanga njira phula, mwa zina, zikhoza kugwiritsidwa ntchito mwa onse zina. Iwo ayenera kusintha katundu osiyanasiyana kwa nkhaniyo. Mwachitsanzo, phula ntchito, chomwe ndi kusintha zigawo zikuluzikulu mu kupanga phula ozizira. Chifukwa cha ntchito zawo pambuyo kuchiritsa ❖ kuyanika si osokoneza mu ozizira ndi kutentha si kusungunula. Pamene ntchito Mac-phula zina amapeza katundu chikutha mofulumira kwambiri.

Kodi anawonjezera kuti phula phula wina? chidwi kwambiri zosinthika wa nkhaniyi analandira zinachitikira akuda ufa mchere ntchito mu kupanga ndondomeko. Kuyambira lero likukhalira wokongola kwambiri phula phula. Ikani iye m'mapaki njira njinga, komanso ntchito chizindikiro patsambali.
