Kushandiswa kwePlastiki Pipes
Sechikamu chakakosha chezvigadzirwa zvekuvakisa zvemakemikari, mapaipi epurasitiki anogamuchirwa zvakanyanya nevashandisi nekuda kwekuita kwavo kwepamusoro, hutsanana, kuchengetedza kwezvakatipoteredza, kushandiswa kwakaderera uye zvimwe zvakanakira, kunyanya zvinosanganisira UPVC drainage pombi, UPVC mvura yekupa pombi, aruminiyamu epurasitiki composite pombi, polyethylene (PE) pombi yekupa mvura, polypropylene PPR pombi yemvura inopisa.
Mapaipi epurasitiki zvinhu zvekuvaka makemikari zvakasanganiswa nehunyanzvi hwepamusoro, uye zvivakwa zvekuvaka makemikari ndiyo yechina iri kubuda yezvivakwa zvitsva zvekuvaka mushure mesimbi, huni uye simende. Mapombi epurasitiki anoshandiswa zvakanyanya muminda yekuvaka mvura uye kudhiraivha, mvura yemumaguta uye yekudhonza uye pombi dzegasi nekuda kwemabhenefiti avo ekurasikirwa kwemvura shoma, kuchengetedza simba, kuchengetedza zvinhu, kuchengetedza kwezvakatipoteredza, kupedzisa kwakaringana uye zvichingodaro, uye vave simba guru rekuvaka pombi pombi network muzana ramakore idzva.
Zvichienzaniswa nemapombi esimbi echinyakare, mapaipi esimbi, mapaipi esimende uye mamwe mapaipi, pombi dzepurasitiki dzine zvakanakira kuchengetedza simba uye kuponesa zvinhu, kuchengetedzwa kwezvakatipoteredza, uremu huremu uye simba rakakwirira, kurwisa ngura, madziro emukati anotsvedzerera pasina scaling, kuvaka nyore uye kugadzirisa, hupenyu hurefu hwebasa uye zvichingodaro. Iwo anoshandiswa zvakanyanya mukuvaka, madhorobha, maindasitiri uye minda yekurima senge kuvaka kwemvura uye dhiraivha, yekumadhorobha uye yekumaruwa mvura uye dhiraivha, gasi remaguta, simba uye optical cable sheath, maindasitiri emvura kutapurirana, kudiridza kwekurima uye zvichingodaro.
Plastiki yakasiyana nezvinhu zvechinyakare. Nhanho yekufambira mberi kwetekinoroji inokurumidza. Kuenderera mberi kwekubuda kwetekinoroji nyowani, zvishandiso zvitsva uye maitiro matsva anoita kuti zvakanakira pombi dzepurasitiki zviwedzere kutaridzika zvichienzaniswa nemidziyo yechinyakare. Kuenzaniswa neyechinyakare simbi pombi uye simende pombi, pombi yepurasitiki ine huremu huremu, iyo inowanzova 1/6-1/10 chete yesimbi pombi. Iyo ine zvirinani corrosion resistance, impact resistance uye tensile simba. Iro mukati mepombi yepurasitiki yakatsetseka kupfuura pombi yesimbi yakakandwa, ine diki friction coefficient uye fluid kuramba. Inogona kuderedza kushandiswa kwesimba rekufambisa kwemvura neanopfuura 5%. Iyo ine yakanaka yakakwana yekuchengetedza simba, uye kushandiswa kwesimba rekugadzira kunoderedzwa ne75%. Izvo zviri nyore kutakura, zviri nyore kuisa, uye hupenyu hwayo hwesevhisi hunosvika 30-50 makore. Mapombi epolyethylene akakurumidza kukura munyika, uye nyika dzakabudirira dzine mukana wakakwana mukushandiswa kwepombi yepolyethylene mumunda wemvura uye gasi. Mapombi epolyethylene haangoshandiswa zvakanyanya kutsiva mapaipi esimbi echinyakare uye pombi dzesimbi, asiwo kutsiva mapaipi ePVC. Chikonzero chiri muhunyanzvi hwekugadzira polyethylene mapaipi. Kune rumwe rutivi, mashoko acho akaita fambiro mberi huru. Kuburikidza nekuvandudzwa kwe polyethylene polymerization yekugadzira maitiro, simba re polyethylene pombi yakakosha zvinhu zvakapetwa kaviri. Kune rimwe divi, kune zvitsva zviri kuitika muhunyanzvi hwekushandisa, sehunyanzvi hwekuisa pombi dzepolyethylene nenzira yekuchera nzira pasina kuchera mapaipi epombi, izvo zvinopa kutamba kwakazara kune zvakanakira pombi dzepolyethylene, kuitira kuti pombi dzechinyakare dzive dzisina kukwikwidza panguva dzakakodzera nzira iyi. Kune zvakare zvakawanda zvitsva zvekushandisa uye matekinoroji ari kudzidzwa, kana akadzidzwa nekuedzwa. Ichokwadi kuti kufambira mberi kwetekinoroji kwepombi dzepurasitiki mumakore gumi anotevera kuchasimudzira kukurumidza kusimudzira uye kushandiswa kwakakura kwepombi dzepurasitiki.
