Double wall corrugated pombi rudzi rutsva rwepombi, ine huremu huremu, simba rakakura, kuvaka kuri nyore, kuchengetedza zvinhu uye zvimwe zvakanakira.Kuenzaniswa nesimba rimwechete rechiedza chemadziro chubhu, inogona kuchengetedza inenge 40% yezvinhu zvakasvibirira, inoshandiswa zvakanyanya mukukurukurirana optical cable sheath, dhiraini yekuvaka, masuwa emvura, minda yekudiridza yakaderera-kudzvinyirira uye mimwe minda.Mumakore achangopfuura, kushandiswa kwekaviri-madziro mabhero kwakawedzera zvishoma nezvishoma, mundima yekutaurirana tambo casing, yakatsiva iyo simende pombi.Kuenzaniswa nedzimwe pombi yepurasitiki, kushandiswa kwayo ndiyo yakakura zvakare.Mumunda wekuvaka dhiraivha, nekuda kwekuita kwayo kwemazwi ekudzivirira kuderera zvishoma, panguva imwe chete, kukwidziridzwa kwepombi fittings hakuna kukwana, saka chiyero hachina kunyanya.Zvisinei, mumanisipala uye fekitari drainage, kunyanya kushandiswa guru dhayamita akavigwa kaviri rusvingo mavhuvhuta ari kuwedzera.Iko kushandiswa kwepaviri madziro marata pombi kana ichienzaniswa neyakafanana dhizaini yepurasitiki light wall pombi mutengo wakaderera, kutenderera kwekuvaka kunogona kupfupikiswa 5 ~ 10 nguva.
China yakatanga kuunza kugadzirwa kwepombi yerudzi urwu kubvira kutanga kwema1990, pakutanga kunyanya diki dhayamita yakatevedzana ye φ 110 kana zvishoma, iyo mbishi inonyanyo shandiswa PVC, inonyanya kushandiswa seyekutaurirana tambo casing.Mumakore achangopfuura, mabhero maviri-madziro zvishoma nezvishoma anokura kusvika kune dhayamita yakakura.Parizvino, mabhero makuru emumba anogona kunge ari φ 1200. Zvinhu zvakashandiswa zvinoshandiswa zvinogadzirwawo kubva MAINLY PVC kusvika PE, PP nezvimwe zvakadaro.Bellows yekugadzira mutsara michina yakakura zvakare kubva pakatanga.Parizvino, mafekitori mazhinji emidziyo yemumba anogona kugadzira mutsara wekugadzira mabhero ane dhayamita kusvika 1200mm.
Kune marudzi matatu e thermoplastics anoshandiswa mumapombi emvura akavigwa: POLYvinyl chloride, polyethylene uye polypropylene.Iyo elastic modulus E yezvinhu zvitatu (maererano nePREN13476-1) ndeye:
Zviripachena, POLYvinyl chloride ndiyo yepamusorosoro, ichiteverwa nepolypropylene uye polyethylene yakaderera.Nokuti iyo elastic modulus E yePOLYvinyl chloride yakakura kudarika iyo ye polyolefin, kuoma kwemhete kwakafanana kunogona kuwanikwa nechinguva chiduku che inertia I. Kana ukashandisa dhizaini yakafanana unogona kushandisa rusvingo ruduku.Mune imwe mhando yePVC yakapetwa kaviri - mabhero emadziro mune mukana wehupfumi, saka mumunda wekuvigwa kwepombi pombi PVC kaviri - madziro mabhero mukutanga application iri zvakare hombe mari.Mumakore achangopfuura, polyolefin double-wall bellows yakagadzirwa nekukurumidza, nekuda kwezvikonzero zvinotevera:
Iyo fluidity uye kugadzikana kwekupisa kwePVC zvinhu hazvina kunaka, saka zvakaoma kuburitsa hombe dhayamita chimiro chemadziro pombi.(Parizvino, kuwanda kwePVC-double-wall bellows mumisika yekune dzimwe nyika kwakaderera kupfuura 500mm. Mumashoko ekutanga, mugadziri mumwe chete anowanikwa achibudisa hupamhi hwe 1000mm.) Polyolefin zvinhu zvinogona kugadzira mabhero ane madziro maviri ane hombe. madhayamita (anonzi anosvika 1800 mm).
Nekuti hapana ruzivo rwehunyanzvi mune izvi kana budiriro yemumba yakavigwa drainpipe inotanga, inotsamira pane bhizinesi kutsvanzvadzira kune dzimwe nzira.
Semuenzaniso, kugadzirwa kwekutanga kwe polyethylene kaviri-madziro mabhero akashandisa PE80 yakakwirira density polyethylene zvinhu zvakakodzera gasi pombi.Ichi chinyorwa kuitira kuti ive nechokwadi chekuchinjika kwepombi yegesi, huremu hwemamorekuru hwakaderera, iyo elastic modulus yakadzikira (pazasi 800Mpa), inoshandiswa mukugadzira mabhero emadziro maviri kazhinji haigone kusvika pakuoma kwemhete inodiwa, vane kuwedzera madziro emadziro, zviri pachena kwete zvehupfumi.Muna 2003, sinopec yanhua kambani yakatungamira mukugadzira 6360M yakakwira density polyethylene HDPE kaviri madziro emarara pombi zvinhu zvekuvigwa mvura muChina zvinoenderana nezvinodiwa nevashandisi, zvichitora ruzivo rwebudiriro yekunze kwemakore mazhinji uye zvinoenderana nezvinodiwa nenyika dzepasirese. mipimo yepamusoro.6360M polymerization process inotora advanced peak peak yekugadzira tekinoroji, kuitira kuti yakakosha zvinhu ive neakakosha mamorekuru cheni chimiro, yakakwira elastic modulus uye panguva imwe chete kuti ive nechokwadi chekupaza kupokana, kukanganisa kuramba uye zvimwe zvivakwa.Mushure maizvozvi, Yanhua yakagadzira zvakakosha zvinhu 7000 zvekuvigwa kwepombi yemvura yakakodzera kune yakakura-dhayamita yepolyethylene kaviri-madziro mabhero.
QHE16A/B, resin yakakosha yemavhuvhu akakura-caliber HDPE kaviri-madziro mabhero akabatanidzwa akabatanidzwa neQilu Petrochemical Research Institute uye fekitori yepurasitiki, yakacherechedzwa nevazhinji vanogadzira mabhero mahombe mahombe uye yave imwe yekutanga uye yakabudirira yakakura-caliber HDPE. kaviri-madziro mabhero akakosha resin akagadzirwa muChina.Ichi chakakosha chinotora fomula nyowani yeS-mhando catalyst, ine yakazara tekinoroji chirongwa, uye ine yakanyanya kunyunguduka simba, kubhenda modulus uye kugadzikana kwekupisa.Iyo hombe-caliber-yakapetwa kaviri-madziro corrugated pombi inogadzirwa neichi chinhu chakakosha ine kupenya kwakanaka, kuomarara kwemhete uye kuita kwekurwisa-kuchembera, inofananidzwa nekuita kwakazara kwezvinhu zvinotengeswa kunze kwenyika, uye inokwanisa kusangana nezvinodiwa zvekugadzira zvehombe-caliber kaviri-madziro. corrugated pipe yemhando dzakasiyana dzekugadzira dzimba.
