Tepi yopanda madzi ya Butyl ndi tepi yosadzipaka yokha yosadzipaka yokha, yosadzipaka yokha, yopangidwa ndi mphira wa butyl monga zopangira zazikulu, pamodzi ndi zowonjezera zina, kudzera muukadaulo wapamwamba.Zimakhala zomatira mwamphamvu pamwamba pa zinthu zosiyanasiyana, ndipo zimakhala ndi nyengo yabwino kwambiri, kukana kukalamba komanso kukana madzi.Imagwira ntchito yosindikiza, kuyamwa kugwedezeka, chitetezo ndi zina zotero pamwamba pa adherend.Mankhwalawa alibe zosungunulira, motero samachepa ndipo samatulutsa mpweya wapoizoni.Chifukwa sichichiza moyo wake wonse, imatha kutsata kufalikira kwamafuta, kuzizira kozizira komanso kusinthika kwamakina pamtunda wa adherend.Ndi zida zapamwamba kwambiri zosindikizira zopanda madzi.
Chifukwa sichichiza kwa nthawi yayitali, imakhala ndi zotsatira zabwino zotsatizana ndi kuwonjezeka kwa kutentha, kuzizira kozizira komanso kusinthika kwa makina a zomatira pamwamba.Ndi zinthu zapamwamba zosalowa madzi.Popeza tepi yomatira yomatira mphira yosalowa madzi ndi yabwino kwambiri, kodi tiyenera kulabadira zinthu zina tikamaigwiritsa ntchito?Ngati mukufunika kutchera khutu, kodi muyenera kulabadira chiyani?Kenaka, malinga ndi zaka zambiri, Juli zipangizo zatsopano zidzalankhula za njira zodzitetezera pakugwiritsa ntchito tepi ya butyl yopanda madzi.
1. Choyamba, tifunika kuwongolera kutentha kwa tepi yotchinga madzi, yomwe nthawi zambiri imayenera kukhala pakati pa 15 ndi 45 digiri.Ngati ili mkati mwa kutentha uku, tiyenera kuchitapo kanthu.Mukagwiritsidwa ntchito, kutentha kwapansi kuyenera kupitilira 5 digiri Celsius kuti zitsimikizire kulimba kwa kulumikizana, komanso kutentha kwapadera kumatha kupangidwa.
2. Malingana ndi zosowa zenizeni za polojekitiyi, sankhani zipangizo zosiyana zosakanizidwa ndi madzi, njira zosiyanasiyana zogwirira ntchito, ndi kusankha mitundu yosiyanasiyana ya matepi omwe ali ndi mawonekedwe ndi kukula kwake.Onetsetsani kuti musankhe chitsanzo choyenera, kukula kwake ndi ndondomeko.
3. Njira yapansi yogwirira ntchitoyo iyenera kukhala yowuma, yopanda dothi loyandama komanso banga lamafuta, ndikupukuta ndi nsalu.Chisamaliro chidzaperekedwanso ku kulimba ndi kukhazikika kwa gawo lomangira la khoma la njerwa kapena pamwamba pa konkriti.Ngati pamwamba pawo ndi poipa, phala la ulusi wa simenti liyenera kugwiritsidwa ntchito pokonzanso kuti malowo akhale afulati komanso olimba popanda mchenga woyandama.
4. Tiyenera kukhala ndi zida zosiyanasiyana zomangira, monga zida zoyeretsera, zodzigudubuza, mipeni yapamapupa, mipeni, ndi zina zotero.
5. Mankhwalawa akagwiritsidwa ntchito, amatha kugwiritsidwa ntchito pokhapokha atavundukula tepi yozungulira.
6. Mangani tepi ya aluminiyumu ya mbali imodzi pamphatiro pakati pa mbale yomiza ndi khoma la simenti, ndikuisindikiza motsatizana kuti ikhale yogwirizana;Ngati 80 mm m'lifupi mwake mbali imodzi ya aluminiyamu zojambulazo zimagwiritsidwa ntchito, mbale yomizayo singagwiritsidwe ntchito.Tepi yambali ziwiri imagwiritsidwa ntchito pomangirira pakati pa zinthu zophimbidwa ndi zophimbidwa, komanso pakati pa zinthu zophimbidwa ndi malo oyambira, ndipo tepi yambali imodzi imagwiritsidwa ntchito pomangira zingwe zakumbuyo ndi doko.
7. Mankhwalawa sangagwiritsidwe ntchito ndi silikoni, methanol, benzene, toluene ethylene ndi zinthu zina zopanda madzi.Itha kukutidwa ndi zinthu zopindika zopanda madzi.Pamene gawo lophimbidwa la zinthu zophimbidwa limangomangiriridwa ndi tepi yomatira, m'lifupi mwake mwazinthu zomata ndi 50mm ndipo m'lifupi mwa tepi yomatira ndi 15mm-25mm.
8. Pogwira ntchito yokhala ndi kalasi yayikulu yopanda madzi, tepi ya 25mm yopanda mbali imodzi ingagwiritsidwe ntchito kusindikiza m'mphepete mwa mawonekedwe.
