Simbi yakasimbisa thermoplastics composite pombiine maitiro akajairwa e-anti-corrosion, hapana kuyera, yakatsetseka yakaderera kuramba, kuchengetedza kupisa hakuna wakisi, kupfeka kusagadzika, huremu huremu uye imwe pombi yepurasitiki, uye chimiro chayo chakasiyana chinogadzirawo zvinotevera maitiro:
(1) Yakanaka inokambaira kuramba uye yakakwirira inogara yakasimba mekinika simba
Nekuti mapurasitiki anokambaira pakamuri tembiricha uye pasi pekunetseka, uye brittle kutyoka kuchaitika pasi pekunetseka kwakanyanya kusingaperi, kushushikana kunobvumidzwa uye kutakura kugona kwemapombi epurasitiki akadzika kwazvo (kazhinji mukati me1.0Mpa).Kusimba kwesimbi kwesimbi kunosvika kagumi kune iyo thermoplastics, uye yakanyatsogadzikana uye haina kunyura mukati mekupisa kwemhando yepurasitiki.Kana iyo mesh simbi waya furemu yakasanganiswa nepurasitiki, zvinokambaira zvepurasitiki zvinogona kudzorwa zvinobudirira uye simba risingaperi repurasitiki rinogona kuvandudzwa zvakanyanya.Naizvozvo, kushushikana kunobvumidzwa kwepolyethylene composite pombi ine waya mesh skeleton yakakwira zvakapetwa kaviri kupfuura iyo yepombi yepurasitiki.
(2) Kudzivirira kwakanaka kwekushisa
Simba repurasitiki tubing rinowanzodzikira nekuwedzera kwekushisa mukati mekushandiswa kwayo tembiricha, uye simba repurasitiki tubing rinodzikira neinopfuura 10% nekuwedzera kwekushisa ne10 ℃.Nokuti kusimba kwewaya mesh skeleton polyethylene composite pombi inenge 2/3 inotakurwa newaya mesh skeleton, saka simba rayo nekuwedzera kwekushandiswa kwekushisa uye kuderera kudarika chero rudzi rwepombi yepurasitiki yakachena.Mhedzisiro dzekuedza dzinoratidza kuti kusimba kwesimbi waya mesh skeleton polyethylene composite pombi inodzikira neisingasviki 5% nekuwedzera kwe10 ℃.
(3) Kuomarara, kunaka kwesimba kuramba, kugadzikana kwakanaka kwedimensional, uye kuchinjika kuri pakati nepakati, kuomarara uye kupfava.
Iyo elastic modulus yesimbi inowanzoita ka200 kupfuura iyo yepamusoro-density polyethylene.Kuomarara, kukanganiswa kwemaitiro uye kugadzikana kwepolyethylene composite pombi ine waya mesh skeleton zviri nani kupfuura chero imwe yakachena pombi yepurasitiki nekuda kwekusimbaradza kwewaya mesh skeleton.Panguva imwecheteyo, nekuti mesh simbi skeleton pachayo inochinjika chimiro, iyo inoumbwa pombi inewo kumwe kuchinjika munzira yeaxial.Naizvozvo, pombi ine hunhu hwekuoma uye kuchinjika musanganiswa, mukurodha uye kurodha, kutakura, kuisirwa kuchinjika uye kuvimbika kwekushanda kwakanakisa.Kuiswa kwepasi kunogona kuchengetedza nhamba yekutsigirwa, mutengo wakaderera;Iyo yepasi pevhu yekumisikidza inogona kumirisana nekukasira kukonzeresa mutoro unokonzerwa ne subsidence, slippage uye mota.Diki dhayamita pombi inogona kukotamiswa zvakanaka, ine dhizaini marongero kana nyoka marongero, chengetedza pombi fittings.
(4) Diki rekuwedzera kwemafuta coefficient
Nekuda kweplastic pombi waya yekuwedzera coefficient ye10.6 ~ 12.2 × 10-6 (1/℃), pombi yepurasitiki yakachena wewaya yekuwedzera coefficient ye170×10-6 (1/℃), waya mesh skeleton polyethylene composite pombi mumambure simbi. skeleton constraints, kuwedzera kwekupisa kwepombi inoumbwa kunovandudzwa zvakanyanya, kuderera kupfuura chero rudzi rwepiipi yepurasitiki inowanzoshandiswa, kuburikidza nebvunzo, Iyo yekuwedzera coefficient yewaya mesh skeleton polyethylene composite pombi ndeye 35.4 ~ 35.9 × 10-6 (1/℃) , inongori 3 ~ 3.4 nguva chete yeyakajairika kabhoni simbi pombi.Mhedzisiro dzekuedza dzinoratidza kuti mudziyo wekubhadhara kupisa hauwanzo kudiwa pakuvigwa, uye pombi inogona kunyudzwa (kana kuburitswa) nekukasira kuisa, zvichidzikisa mutengo wekuisa.
(5) Kukurumidza kutsemuka hakuzoitiki
Pure epurasitiki pombi, kunyanya yakakura dhayamita yakachena epurasitiki pombi pakudziya kwakadzika pasi pechiito chekuramba kuchitenderera kushushikana, nyore kugadzira kukurumidza kutsemuka kunokonzerwa nekuremara kwenzvimbo, kushushikana kwepfungwa (pakarepo mazana emamita kusvika makiromita pamusoro), saka parizvino, iyo nyika inokurumidza. kuputika kupikisa kwepombi yepurasitiki kunoisa mberi zvinodiwa, uye yakaderera kabhoni simbi haipo brittle fracture dambudziko, Kuvapo kwesimbi mesh kunodzivirira deformation uye kushushikana kwepurasitiki kuti isasvike padanho rakakosha rekutsemuka nekukurumidza.Naizvozvo tichitaura, hapana kukurumidza kutsemuka kwewaya mesh furemu polyethylene composite pombi.
6) Iyo inoumbwa nesimbi uye epurasitiki zvinhu yunifomu uye yakavimbika
Parizvino, iyo simbi-yepurasitiki inoumba pombi pamusika nekuti iyo inoumbwa pamusoro pesimbi nepurasitiki inogara yakajairwa interface, kushandiswa kwenguva refu pasi pechiito chekuchinjana kushushikana kuri nyore delamination, zvichikonzera kudonha kwemajoini, mukati mebhodhoro shrinkage, blockage uye kukundikana.Kuenzaniswa newaya mesh skeleton polyethylene composite pombi is mesh dhizaini kuburikidza yakakosha inopisa inonyunguduka inonamira (yakagadziridzwa HDPE) kuitira kuti purasitiki newaya mesh zvakanyatsobatanidzwa uye zvakabatanidzwa.Simba rinosungirirana rezvinhu zviviri izvi zvakakura uye yunifomu, uye kushushikana kudiki.
7) Kaviri-sided anticorrosion
Simbi waya mesh skeleton inoumbwa mupurasitiki kuburikidza neyakagadzika inopisa inonyungudika.Nzvimbo dzemukati nekunze dzepombi dzine maitiro akafanana ekudzivirira kupisa, kusapfeka, madziro emukati anotsvedzerera, kushomeka kwekutapurirana, hapana kuyera, hapana wakisi, mhedzisiro inochengetedza simba, inodhura uye yakanakira kuvigwa kwekufambisa uye nharaunda inoparadza. mamiriro.
(8) Akanaka kuzvitsvaga
Nekuda kwekuvapo kwewaya mesh skeleton, iyo yakavigwa waya mesh skeleton polyethylene composite pombi inogona kuwanikwa neyakajairwa magineti yekuona nzira, kudzivirira kukuvara kwakakonzerwa nemamwe mapurojekiti ekuchera.Uye rudzi urwu rwekukuvadza ipurasitiki yakachena pombi uye imwe isiri-simbi pombi kuti ibudise zvakanyanya kukuvadza.
(9) Kugadzirisa uye kuchinjika kwechigadzirwa chimiro uye kuita
Mamiriro uye kuita kwechigadzirwa kunogona kugadziridzwa nekuchinja dhayamita yewaya, kuparadzaniswa kwemambure, ukobvu hweplastic layer, plastiki uye mhando, kuitira kuti isangane nezvinodiwa zvekumanikidza kwakasiyana, tembiricha uye ngura. resistance.
(10) Special electric fusion joint, zvakasiyana-siyana, kuiswa kunokurumidza uye kwakavimbika
Kubatanidzwa kwesimbi waya mesh furemu polyethylene composite pombi inotora electrothermic kubatana uye flange kubatana.Electrothermic connection kuisa pombi inoumbwa mupombi yeelectrothermic pombi, uye kuisa magetsi pawaya yekudziya yemagetsi yakaiswa mukati mepombi inokwana kuti ipise.Kutanga, nzvimbo yemukati yepombi inosungirirwa inonyungudutswa kuti ibudise kunyunguduka, uye kunyunguduka kunowedzera uye kunozadza mukaha wepombi inokodzera kusvikira kunze kwepombi kuchibudisa kunyunguduka, uye iyo miviri inonyunguduka pamwe chete.Mushure mekutonhora uye kuumba, pombi uye pombi fitting yakanyatsobatanidzwa seyese.
