Mumapurojekiti einjiniya akavanzika—akadai sematuneri, nzira dzepasi pevhu, uye nzira dzekushandisa pasi pevhu—mamembrane ekudzivirira mvura haangoshandi sezvipingamupinyi zvekuparadzanisa mvura chete, asiwo se “zvinhu zvinochinjika” zvinotora chikamu mukudzora kushushikana kwechimiro. Semugadziri ane hunyanzvi mumunda we geosynthetics, Shandong Hongyue Environmental Engineering Co., Ltd. (inozonzi "Hongyue Environmental") yakashandisa hunyanzvi hwayo hwakadzama muEVA (Ethylene-Vinyl Acetate Copolymer) mamembrane ekudzivirira mvura kugadzira sisitimu yekuvaka yesainzi, yakasimba, uye yakajairika. Kuburikidza nematekiniki matatu makuru—”kusarudza zvinhu nemazvo, kusanganisa kwakanyatsonaka, uye kusimba kwakajairika”—kambani iyi inoshandisa zvizere hunhu hwakanaka hwemamembrane eEVA, kusanganisira kureba kwakanyanya, kuramba kupisa kwakaderera, uye simba rekubvaruka, nokudaro ichigadzira dziviriro isingapindiki yekudzivirira mvura kune akasiyana mapurojekiti einjiniya.
Danho Rokutanga: Kusarudza Zvinhu Nemazvo Uye Kugadzirira Substrate—Kuisa Nheyo Isina Chikanganiso
Chirongwa chekudzivirira mvura chemhando yepamusoro chinotanga nekudzora zvinhu nemazvo. Mamembrane ekudzivirira mvura eHongyue Environmental EVA anoshandisa Ethylene-Vinyl Acetate Copolymer yepamusoro sezvinhu zvavo zvikuru; anoratidza kusimba kwakaita serabha, ane kuchinjika kwakanaka kwekupisa kwakaderera (kuchengetedza kuchinjika kunyangwe mumamiriro ekunze anotonhora kubva -30°C kusvika -35°C), uye ane simba guru rekubvarura. Isati yagadzirwa, substrate inofanira kugadziriswa zvakasimba: pamusoro pechigadziko inofanira kunge yakati sandara, yakasimba, uye isina zvipingamupinyi kana zvinhu zvakapinza, ukuwo ichiita kuti isave nemvura yakamira, mavara emafuta, uye guruva. Zvichienderana nehukuru hwepurojekiti nenzvimbo yayo chaiyo yekushanda, Hongyue Environmental inopa mamembrane ekudzivirira mvura eEVA akagadziriswa muukobvu hwakasiyana-siyana—kubva pa0.5 mm kusvika 2.5 mm—kuti ive nechokwadi chekuti pane chiyero chakanaka pakati pekushanda kwezvinhu nezvinodiwa zveinjiniya.
Danho Rechipiri: Maitiro Akakomba Ekuwelda—Kuona Nguva Yehupenyu HweSisitimu Yekudzivirira Mvura
Panguva yekuvaka panzvimbo iyi, kuvimbika kwe membrane yekudzivirira mvura kunoenderana ne90% kubva pamhando ye welding yemhepo inopisa. Chikwata chehunyanzvi cheHongyue Environmental chinosimbisa kuti pfungwa isiriyo yekutarisa welding se "basa rekufukidza" inofanira kusiyiwa; pachinzvimbo, inofanira kukosheswa senzira yakakosha uye yakakosha. Kuvaka kunofanirwa kuitwa uchishandisa michina yekuwelda yakasarudzika kana pfuti dzekuwelda dzemhepo inopisa, tembiricha yekubuda kwemhepo ichidzorwa zvakanyanya mukati me320°C kusvika 380°C. Usati wawelda, upamhi hwepakati pemapepa e membrane ari pedyo hunofanira kudzorwa nemazvo pakati pe70 mm ne100 mm, uye bhurashi resimbi rinofanira kushandiswa kubvisa guruva repamusoro kana zvidimbu zvakasanganiswa kubva munzvimbo dzinopindirana. Munguva yekuwelda, tembiricha dzakakwirira dzinoshandiswa kunyungudutsa pamusoro pechinhu cheEVA, zvichiteverwa nekushandiswa kwekumanikidza kubatanidza zvidimbu kuita unit imwe chete, yakabatana. Kuongorora mushure mekuwelda kunosanganisira maitiro ekuongorora matanho matatu akaomarara: Chekutanga, kuongororwa kwemaziso kunoitwa kuti ive nechokwadi chekuti weld seam inoonekwa seyakafanana, yakajeka, yakafanana negirazi, isina mabhuru kana makwinya. Chechipiri, bvunzo yeganda remakanika inoitwa; kana simba rekusunga rikaitwa rakatarisa pamusungo we weld, rinofanira kuramba rakadaro risina kutsemuka. Chechitatu, pazvinenge zvichidikanwa, bvunzo ye inflation inoitwa kuti ione kana kuora kwe pressure kuri mukati memiganhu yakatarwa.
Danho rechitatu: Kusawirirana kweSainzi uye Kuisa—Kubvisa Njodzi ye "Welds Dzenhema"
Panguva yekuvaka munzvimbo dzakaoma—dzakadai semakorona emugero—kuzviremera kwezvinhu zvinogona kukonzera kuti zvitsvedze, zvichikonzera “kutsvedza kwenhema” (misono isina kukwana kana isina simba). Kudzivirirwa Kwezvakatipoteredza kweHongyue kunosimbisa zvakanyanya kukosha kwekushandisa nzira ye “kutsvedza kwenzvimbo uye kutsvedza kwakapatsanurwa”. Izvi zvinosanganisira kutanga kubatanidza membrane yekudzivirira mvura kusubstrate uchishandisa zvirauro zvakatemwa zvakaparadzana ne300mm; kutsvedza kunozoburitswa chikamu nechikamu, nekutsvedza kunoitwa panguva imwe chete. Nzira iyi inodzivirira kuitika kwekunyedza kwenhema kunokonzerwa nekutsvedza kwezvinhu pasi pehuremu hwazvo, nokudaro ichivimbisa chisungo chakasimba, chepedyo pakati pemembrane yekudzivirira mvura nechimiro chekutanga chekutsigira. Uyezve, membrane yekudzivirira mvura yeEVA inoratidza kubatana kwakakura neadhesives dzakasiyana-siyana; panguva yekurapa kwakadzama kwemakona, kupinda kwepombi, nedzimwe nzvimbo dzakaoma, adhesives dzakasarudzika dzinogona kushandiswa kuti dzivhare nekukurumidza uye zvinobudirira, nokudaro dzichiwedzera kusapinda kwese kwesystem yekudzivirira mvura.
Vachishandisa nzira idzi dzekuvaka dzakajairwa, mamembrane eEVA ekudzivirira mvura eShandong Hongyue Environmental Protection anokwanisa kuratidza zvakanakira zvawo zvikuru—kusanganisira kuramba hydrolysis zvakanyanya, kuramba kupinda kwemidzi, uye kugara kwenguva refu.
