Zida Zotsekera Madzi
Zida zotsekera madzi zimatha kugawidwa m'magulu awiri: kutsekereza madzi kogwira ntchito komanso kutsekereza madzi osagwira. Kutsekereza kwamadzi kumagwiritsa ntchito zinthu zoyamwa madzi komanso zotupa zomwe zimagwira ntchito. Pamene sheath kapena cholumikizira chawonongeka, zinthuzi zimakula zikakumana ndi madzi, ndikuchepetsa kulowa kwake mkati mwa chingwe. Zida zoterezi zikuphatikizapomadzi kuyamwa gel osakaniza, tepi yotsekereza madzi, ufa wotsekereza madzi,ulusi wotsekereza madzi, ndi chingwe chotsekereza madzi. Kutsekereza madzi osasunthika, Komano, kumagwiritsa ntchito zida za hydrophobic kutsekereza madzi kunja kwa chingwe pamene sheath yawonongeka. Zitsanzo za zinthu zotsekereza madzi osagwira ntchito ndi phala lodzaza ndi mafuta, zomatira zotentha zosungunuka, ndi phala lokulitsa kutentha.
I. Zida Zotsekera Madzi Osayenda
Kudzaza zinthu zotsekereza madzi, monga petroleum paste, mu zingwe inali njira yoyamba yotsekera madzi mu zingwe zamagetsi zoyambilira. Njirayi imalepheretsa madzi kulowa mu chingwe koma ili ndi zovuta izi:
1.Imawonjezera kwambiri kulemera kwa chingwe;
2.Imachititsa kuchepa kwa chingwe cha conductive ntchito;
3.Petroleum phala imayipitsa kwambiri zingwe za chingwe, kupangitsa kuyeretsa kukhala kovuta;
4.Kudzaza kwathunthu kumakhala kovuta kulamulira, ndipo kudzaza kosakwanira kungapangitse kuti madzi asatseke bwino.
II. Zida Zoletsa Madzi Zogwira Ntchito
Pakali pano, zipangizo zotsekera madzi zomwe zimagwiritsidwa ntchito m'zingwe zimakhala makamaka tepi yotchinga madzi, ufa wotchinga madzi, chingwe chotchinga madzi, ndi ulusi wotsekera madzi. Poyerekeza ndi petroleum phala, yogwira madzi kutsekereza zipangizo ali ndi makhalidwe awa: mkulu mayamwidwe madzi ndi mkulu kutupa. Amatha kuyamwa madzi mwachangu ndikutupa mwachangu kuti apange chinthu chofanana ndi gel chomwe chimatchinga kulowa m'madzi, potero kuonetsetsa chitetezo chachitetezo cha chingwe. Kuphatikiza apo, zida zotchingira madzi zogwira ntchito ndizopepuka, zoyera, komanso zosavuta kuziyika ndikujowina. Komabe, amakhalanso ndi zovuta zina:
1.Water-blocking powder ndizovuta kugwirizanitsa mofanana;
2.Tepi yotchinga madzi kapena ulusi ukhoza kuonjezera m'mimba mwake, kusokoneza kutentha kwa kutentha, kufulumizitsa kukalamba kwa chingwe, ndi kuchepetsa mphamvu yotumizira chingwe;
3.Zinthu zotsekera madzi zogwira ntchito nthawi zambiri zimakhala zodula.
Kuwunika Kutsekereza Kwamadzi :Pakali pano, njira yayikulu ku China yolepheretsa madzi kulowa muzitsulo zotchingira zingwe ndikuwonjezera wosanjikiza wosalowa madzi. Komabe, kuti tikwaniritse kutsekereza madzi okwanira mu zingwe, sitiyenera kungoganizira zolowera m'madzi a radial komanso kupewa kufalikira kwamadzi nthawi yayitali ikalowa mu chingwe.
Polyethylene (Mchimake Wamkati) Wodzipatula Wopanda Madzi: Kutulutsa wosanjikiza wotsekereza madzi wa polyethylene, kuphatikiza ndi nsanjika yotengera chinyezi (monga tepi yotchinga madzi), imatha kukwaniritsa zofunikira pakutsekereza madzi kwautali komanso kuteteza chinyezi mu zingwe zomwe zimayikidwa m'malo onyowa pang'ono. Chosanjikiza chotchinga madzi cha polyethylene ndi chosavuta kupanga ndipo sichifuna zida zowonjezera.
Pulasitiki Coated Aluminium Tape Polyethylene Bonded Waterproof Isolation Layer: Ngati zingwe zayikidwa m'madzi kapena malo onyowa kwambiri, mphamvu yotchinga madzi ya zigawo zodzipatula za polyethylene zitha kukhala zosakwanira. Pazingwe zomwe zimafuna kutsekereza kwamadzi kwamphamvu kwamadzi, ndizofala kukulunga tepi ya aluminiyamu-pulasitiki kuzungulira pachimake. Chisindikizochi chimakhala ndi nthawi mazana kapena masauzande ambiri osamva madzi kuposa polyethylene yoyera. Malingana ngati msoko wa tepi yophatikizika umakhala womangika ndikusindikizidwa, kulowa m'madzi sikutheka. Tepi yophatikizika ya aluminium-pulasitiki imafuna kukulunga kotalika ndi kulumikiza, komwe kumaphatikizapo ndalama zowonjezera komanso kusinthidwa kwa zida.
Muzochita zaumisiri, kukwaniritsa kutsekereza kwamadzi kwautali kumakhala kovuta kwambiri kuposa kutsekereza madzi ozungulira. Njira zosiyanasiyana, monga kusintha makina opangira makina opangira makina okhwima, zakhala zikugwiritsidwa ntchito, koma zotsatira zake zakhala zochepa chifukwa pali mipata mu makina osindikizira omwe amalola madzi kufalikira kudzera mu capillary action. Kuti mukwaniritse kutsekereza kwamadzi kwanthawi yayitali, ndikofunikira kudzaza mipata mu conductor wotsekeka ndi zinthu zotsekereza madzi. Miyezo iwiri yotsatirayi ndi zomangira zitha kugwiritsidwa ntchito kukwaniritsa kutsekereza kwamadzi kwakutali mu zingwe:
1.Kugwiritsa ntchito ma conductor otsekereza madzi. Onjezani chingwe chotchinga madzi, ufa wotsekereza madzi, ulusi wotsekereza madzi, kapena kulungani tepi yotsekereza madzi mozungulira kokitala yotsekeka.
2.Kugwiritsa ntchito zida zotsekereza madzi. Panthawi yopangira chingwe, lembani pachimake ndi ulusi wotsekereza madzi, chingwe, kapena kukulunga pachimake ndi tepi yotsekereza kapena yotsekereza madzi.
Pakalipano, vuto lalikulu la kutsekereza madzi kwa nthawi yayitali liri muzitsulo zoletsa madzi-momwe mungadzazire zinthu zoletsa madzi pakati pa oyendetsa ndi zomwe zimalepheretsa madzi kuti zigwiritse ntchito zimakhalabe cholinga cha kafukufuku.
Ⅲ. Mapeto
Ukadaulo wotsekereza madzi wa radial umagwiritsa ntchito zigawo zodzipatula zotsekereza madzi zomwe zimakulungidwa mozungulira kondakitala, ndikuwonjezedwa kunja kwa khushoni yotengera chinyezi. Pazingwe zokhala ndi mphamvu yapakati, tepi ya aluminiyamu-pulasitiki yophatikizika imagwiritsidwa ntchito kwambiri, pomwe zingwe zothamanga kwambiri nthawi zambiri zimagwiritsa ntchito majekete osindikizira achitsulo, aluminiyamu, kapena zitsulo zosapanga dzimbiri.
Ukadaulo wotsekereza madzi kwautali wotalikirapo umayang'ana kwambiri kudzaza mipata pakati pa zingwe zowongolera ndi zida zotsekereza madzi kuti ziletse kufalikira kwa madzi pachimake. Kuchokera pazitukuko zamakono zamakono, kudzaza ndi ufa wotsekera madzi ndikothandiza kwambiri poletsa madzi otalikirapo.
Kupeza zingwe zopanda madzi kudzasokoneza kutentha kwa chingwe ndi magwiridwe antchito, kotero ndikofunikira kusankha kapena kupanga mawonekedwe oyenera otsekera madzi potengera zofunikira zaukadaulo.
