Polyethylene pombi (PE mapaipi) anoshandiswa zvakanyanya mukugovera mvura, kutapurirana gasi, kudiridza kwekurima, uye kushandiswa kwemaindasitiri. Zvakanakira zvavo, senge corrosion kuramba, kuchinjika kwakanyanya, uye hupenyu hurefu hwesevhisi, zvinovaita chinhu chakakosha chemazuva ano pombi masisitimu. Zvichienderana nekuwanda kwezvinhu, chimiro chechimiro, uye mashandisirwo, mapaipi epolyethylene anogona kuiswa mumhando dzinoverengeka, imwe neimwe iine akasiyana maitiro ekuita uye anoshanda mamiriro.
Classification by Density
Mapombi epolyethylene anonyanya kuiswa muzvikamu zvitatu zvichienderana nekuwanda kwezvinhu zvawo: low-density polyethylene (LDPE), yepakati-density polyethylene (MDPE), uye yakakwirira-density polyethylene (HDPE).
1. Mapaipi Akaderera-Density Polyethylene Pipes (LDPE)
Mapaipi eLDPE akagadzirwa kubva ku-density polyethylene uye ane kunyanduka kukuru uye kusamira zvakanaka, asi simba rakaderera. Kuchinjika kwavo kunoita kuti ive yakakodzera kune maapplication anoda kukotama, senge ekurima yekudiridza madhirigi uye emagetsi tambo conduits. Zvisineyi, nekuda kwekusasimba kwawo, mapaipi eLDPE haawanzo shandiswa pakufambisa-kukwira kwemvura.
2. Pakati-Density Polyethylene (MDPE) Pipe
MDPE pombi ine density pakati LDPE uye HDPE, ichibatanidza dhigirii kuchinjika pamwe yakakwirira kuramba kwezvakatipoteredza stress kuparuka. MDPE pombi inowanzo shandiswa mugasi pombi masisitimu nekuti yayo yakanaka weldability uye zvine mwero kumanikidza kuramba kunosangana nezvinodiwa zvekuchengetedza gasi kutapurirana. Pamusoro pezvo, MDPE pombi inokodzerawo kune mamwe masisitimu ekupa mvura, asi kushandiswa kwayo kunogumira pane iyo HDPE pombi.
3. High-Density Polyethylene (HDPE) Pipe
HDPE pombi parizvino ndiyo inonyanya kushandiswa mhando yepombi yepolyethylene. Yayo yakakwirira density uye yakakwirira crystallinity inoipa iyo yakanyanya kudzvanywa kuramba, abrasion kuramba, uye kugadzikana kwemakemikari. HDPE pombi inoshandiswa zvakanyanya mukupa mvura yemunisiparati, kudhiraivha, kutapurirana gasi, uye kufambisa kwemvura yeindasitiri, uye hupenyu hwayo hurefu hwesevhisi (kusvika kumakore makumi mashanu kana kupfuura) uye kuramba kwekuora kunoita kuti ive yakanaka kutsiva mapaipi esimbi echinyakare.
Kurongeka neFomu reKuvaka
Pamusoro pe density classification, pombi dzepolyethylene dzinogona kuiswawo maererano nechimiro chadzo kuita mapaipi akasimba-pamudhuri, mapaipi ane marata, mapaipi -ane marata maviri, uye simbi{2}}pombi dzepurasitiki dzakasanganiswa.
1. Pombi-yakasimba yepolyethylene yemadziro: Mapaipi ePE epamudhuri akasimba-ane kukora kwemadziro akaenzana, anopa kusamira zvakanaka kwekumanikidza uye kufamba zvakanaka kwemvura. Dzakakodzera kushandiswa kunoda simba repombi yakakwirira, yakadai seyepamusoro{{4}kupindwa kwemvura nepressure uye kutapurirana gasi.
2. Corrugated polyethylene pombi: Corrugated pombi dzinowedzera kuchinjika uye kuramba kumanikidzwa kwekunze kuburikidza nemarara emadziro pamadziro epombi. Anowanzo shandiswa mumadhiraini masisitimu, makonditi, uye-zvishandiso zvisina kumanikidza. Kuiswa kwavo kwakareruka uye kuri nyore kunoita kuti vashandiswe zvakanyanya mukuvaka uye mainjiniya einjiniya.
. Iyo yekunze layer ine corrugated structure yekuwedzera pressure resistance, ukuwo yemukati layer ine mudhuri wakatsetseka kuti uderedze kusamira kwemvura. Rudzi urwu rwepombi runonyanya kushandiswa mumataundi emvura uye masisitimu etsvina, achibatanidza hupfumi uye kushanda.
4. Simbi-pombi yeplastic composite polyethylene: Simbi-mapombi akaumbwa epurasitiki anosanganisa kusaita ngura kwepolyethylene nekusimba kukuru kwesimbi. Ivo vanowanzo shandisa HDPE seyemukati lining uye inosimbiswa nesimbi mitsetse kana waya kunze. Dzakakodzera-kufambiswa kwemvura mumaindasitiri kana masisitimu epombi munzvimbo dzakakosha.
Classification by Application
Zvichienderana nemamiriro ezvinhu ekushandisa, pombi dzepolyethylene dzinogona kukamurwazve kuita pombi dzemvura, pombi dzegasi, pombi dzekudiridza dzekurima, uye pombi dzemaindasitiri. Semuenzaniso, mapaipi emvura ePE emvura anosangana nemiyero yehutsanana yemvura yekunwa inoda kupasa zvitupa zvakakodzera (senge NSF, ISO, nezvimwewo) kuve nechokwadi chekuchengetedzwa kwemhando yemvura; nepo PE mapaipi ekupa gasi anofanirwa kusangana nezvinodiwa zvakasimba zvekuramba kunonoka kutsemuka kukura uye kumanikidza kuramba.
Mapombi epolyethylene anogona kuiswa nenzira dzakasiyana-siyana, aine marudzi akasiyana emapombi ane maonero akasiyana maererano nemidziyo, chimiro, uye mashandisirwo. Kusarudza nemazvo mhando yepombi yepolyethylene inoda kutariswa kwakadzama kwezvinhu zvakaita seyepakati inotakurwa, kudzvanywa kwekushanda, mamiriro ekunze, uye kuisirwa zvinodiwa. Nekufambira mberi kwesainzi yemidziyo, kuita kwepombi dzepolyethylene kunoramba kuchigadziriswa, uye tarisiro yekushandiswa kwayo mumapurojekiti akasiyana einjiniya inozowedzera.
