Pakalipano, njerwa zomwe zimagwiritsidwa ntchito kwambiri mumsewu wakhungu ndi njerwa za misewu ya ceramic, njerwa za msewu wa simenti, njerwa zapamsewu zakhungu, njerwa zapamsewu wa mphira, ndi zina zotero, zomwe zili ndi ubwino wake wapadera.
Msewu wakhungu ndi mtundu wa malo amsewu omwe ndi ofunikira kwambiri kuyika, chifukwa ndi tile yapansi yopangidwira mwapadera kwa akhungu. , akhungu road board, blind road film.
Njerwa zoyala misewu yakhungu nthawi zambiri zimamangidwa ndi mitundu itatu ya njerwa, imodzi ndi njerwa yowongolera njira, yomwe imatsogolera akhungu kupita patsogolo ndi chidaliro, yomwe imatchedwa njerwa yamsewu wakhungu, kapena njerwa yowongolera njira yolowera njira yakhungu; ina ndi njerwa yachangu yokhala ndi madontho. , kusonyeza kuti pali chopinga pamaso pa wakhungu, ndi nthawi kutembenuka, amatchedwa akhungu msewu njerwa, kapena wakhungu msewu wotsogolera njerwa; mtundu wotsiriza ndi njerwa yochenjeza za ngozi yapamsewu yakhungu, kadontho kamakhala kokulirapo, apolisi sayenera kupitirira, ndipo kutsogolo kwake ndi koopsa.
Mitundu yeniyeni ndi iyi:
1. Njerwa yakhungu ya ceramic. Ndizinthu za ceramic, zomwe zimakhala ndi porcelainization yabwino, kuyamwa kwa madzi, kukana chisanu ndi kupanikizika, maonekedwe okongola, ndipo nthawi zambiri amagwiritsidwa ntchito m'malo omwe amafunidwa kwambiri monga masitima apamtunda ndi ma subways, koma mtengo wake ndi wokwera mtengo kwambiri.
2. Njerwa zapamsewu za simenti. Mtengo wopangira njerwa zamtunduwu ndi wocheperako, ndipo zinyalala zachiwiri zobwezeretsanso zinyalala zitha kugwiritsidwa ntchito. Ndiwokonda zachilengedwe komanso wotchipa, ndipo nthawi zambiri ndi yoyenera pazosowa zotsika monga misewu yanyumba. Koma moyo wautumiki ndi waufupi.
3. Sintered blind road njerwa. Njerwa zamtunduwu zimagwiritsidwa ntchito kwambiri, zomwe zimagwiritsidwa ntchito mbali zonse za misewu yamatauni, zoyenera kugwiritsidwa ntchito panja. Koma n'zosavuta kukhala zauve ndi zovuta kuzisamalira ndi kuyeretsa.
4. Njerwa ya msewu wa mphira. Ndi mtundu watsopano wa akhungu msewu mankhwala njerwa, amene ali oyenera kukonza zosintha mu siteji oyambirira, ndipo ntchito pomanganso kenako akhungu msewu njerwa, amene ndi yabwino yomanga.
Njerwa zapamsewu zosawona zimagawidwa kukhala njerwa zapamsewu zachikasu ndi njerwa zapamsewu zotuwa, ndipo pali kusiyana pakati pa njerwa zoyimitsa ndi njerwa zakutsogolo.
Zomwe zimafotokozedwa ndi 200 * 200, 300 * 300, zomwe ndizomwe zimagwiritsidwa ntchito ndi boma m'malo ogulitsira ndi masitima apamtunda.
