Zida zopangira zopangiraMakamaka polyethylene (pe) ndi polypropylene (ma pp), ndipo polyvinyl chloride ndi polyamidi akhoza kugwiritsidwanso ntchito. Masamba ali ngati utoto wobiriwira kutsanzira udzu wachilengedwe, ndipo zotayika za ultraviolet zikufunika kuwonjezeredwa. Polyethylene (pe): Zimamveka zofewa, ndipo maonekedwe ake ndi masewera ake ali pafupi ndi udzu wachilengedwe, womwe umalandiridwa ndi ogwiritsa ntchito. Ndizinthu zomwe zimagwiritsidwa ntchito kwambiri zopangira udzu wa udzu pamsika. Polypropylene (pp): Phazi la udzu ndilovuta, nthawi zambiri oyenera makhothi amilandu, malo oweta, matraws kapena zokongoletsera. Kubzala kukana kumachitika pang'ono kuposa polyethylene. Nylon: Ndikomwe koyambirira kwa mbewu yopanga udzu ndi m'badwo wachiberekero cha udzu.
Kapangidwe ka zinthu kapangidwe kamene kamakhala ndi zinthu zitatu za zigawo zitatu za zida. Dera loyera limapangidwa ndi dothi lomwe limakhala ndi dothi, miyala yamiyala ndi phula kapena konkriti. Umu wosanjikiza umayenera kukhala wokhazikika, wosalala, wosalala komanso wopanda ungwiro, ndiye kuti, munda wamba. Chifukwa cha gawo lalikulu la munda wa hockey, maziko osanjikiza ayenera kugwiritsidwa ntchito bwino pomanga kuti aletse kumira. Ngati konkriti yolumikizira imayikidwa, kulumikizana kwakukula kuyenera kudulidwa pambuyo pa konkriti kumachiritsidwa kuti zitheke kusintha matenthedwe ndi ming'alu. Pamwamba pa maziko ndi cholembera, nthawi zambiri chimapangidwa ndi mphira kapena pulasitiki. Huble ali ndi vuto lalikulu komanso makulidwe a 3 ~ 5mm. Chida cha thovu ndi chotsika mtengo, koma chosawoneka bwino komanso makulidwe a 5 ~ 10mm. Ngati ndi yolimba kwambiri, udzu udzakhala wofewa komanso wosavuta kunyoza; Ngati ndi yowonda kwambiri, imasowa kwambiri ndipo sidzagwira ntchito yobwezeretsa. Wosanjidwa wokhomerera ayenera kuphatikizidwa ndi maziko osanjikiza, nthawi zambiri amakhala ndi masamba oyera kapena guluu. Wosanjikiza wachitatu, womwe ndinso wosenda, ndiye wosanjikiza. Malinga ndi mawonekedwe opangidwa, pali hubf atch, yozungulira ya naylon, yowoneka bwino ya Polyplenee fir, ndipo yolumikizidwa ndi imf yolumikizidwa ndi mafinya a nayiloni. Izi zimayeneranso kutsukidwa ku mphira kapena pulasitiki yovuta ndi lala. Pomanga, guluu iyenera kuyigwiritsa ntchito kwathunthu, nazingizidwa mwamphamvu, ndipo makwinya amatha kupangidwa. Kwina, pali mitundu iwiri ya zigawo za Turf: 1. Ulusi wowoneka bwino wa turf wosanjikiza ndi wowonda, koma 1.2 ~ 1.5mm; 2. Mafuta a Turf ali owuma, 20 ~ 24mm, ndipo quartz amadzaza pafupifupi pamwamba pa fiber.
Chitetezo Chachilengedwe
Polyethylene, gawo lalikulu la turf yopanga, sikuti ndi zinthu zopanda biodegrad. Pambuyo pa 8 mpaka 10 zaka zaukalamba ndi kuchotsedwa, zimapangitsa zinyalala za police. M'mayiko akunja, nthawi zambiri amafupikitsidwa ndikuwonongeka ndi makampani, kenako ndikubwezerezedwanso. Ku China, itha kugwiritsidwa ntchito ngati maziko othamanga pa upangiri wa msewu. Ngati malowa asinthidwa kukhala magwiridwe ena, maziko omwe amapangidwa ndi phula kapena konkriti ayenera kuchotsedwa.
Ubwino
Makina opanga ali ndi maubwino owoneka bwino, obiriwira chaka chonse, zowoneka bwino, zochulukirapo, moyo wautali, komanso ndalama zochepa.
Mavuto Pomanga:
1. Kukula kwa chizindikiro sikolondola kokwanira, ndipo udzu woyera suli wowongoka.
2. Mphamvu ya belt yolumikizira sikokwanira kapena gululo la udzu silikugwiritsidwa ntchito, ndipo udzu umatembenuka.
3. Mzere wogwirizana wa tsambali ndi yodziwikiratu,
4. Kuwongolera kwa malo okhala silika sikunakonzekere pafupipafupi, ndipo mawonekedwe opepuka amayamba.
5. Pamwamba pa tsambalo sikogwirizana chifukwa cha jakisoni wa mchenga ndi mictamele kapena makwinya a udzu sanakonzedwetu.
6. Tsambali lili ndi fungo kapena kusinthanitsa, zomwe zimachitika makamaka chifukwa cha zosefera.
Mavuto omwe ali pamwambawa omwe amakonda kuchitika nthawi yomanga akhoza kupewedwa bola
