Uri kutarisa magadzirirwo emapaipi wobva waona makodhi akaita sePE80 nePE100. Aya mazwi ehunyanzvi anovhiringidza, uye kusarudza mhando isiriyo kunogona kukanganisa kuvimbika kwenguva refu kweprojekiti yako.

PE100 zvinoreva kuti pombi iyi yakagadzirwa kubva mukugadzirwa kwazvino kweHigh-Density Polyethylene (HDPE). Iyo "100" inoratidza Simba Rinodiwa (MRS) re10.0 MPa. Izvi zvinoita kuti ive chinhu chakasimba uye chinogara kwenguva refu chinobvumira madziro epombi akatetepa ane kumanikidzwa kwakafanana.

Pandinotaura nevanotenga vakaita saBudi, magiredhi aya ezvinhu anowanzo taurwa. Zviri nyore kuaona semanhamba chete, asi "PE100" inomiririra makumi emakore ekufambira mberi kwesainzi yezvinhu. Chipikirwa chekusimba, kuvimbika, uye kushanda kwenguva refu. Kunzwisisa zvinorehwa nekodhi iyi iri nyore ndicho chinhu chikuru chekuita sarudzo yekutenga yakangwara iyo inovimbisa kubudirira kwemasisitimu ako ekutarisira mvura kwemakore anotevera. Ngationgororei zvinorehwa negiredhi iri kumapurojekiti ako.

Ko PE100 iri nani pane PVC here?

PVC chinhu chinozivikanwa uye chinowanzova nemutengo wakaderera pakutanga. Izvi zvinoita kuti zvikwezve kusarudza, asi kuomarara kwayo uye nzira yekubatanidza zvinogona kutungamira kumatambudziko emangwana uye mitengo yakakwira.

Pamvura yakavigwa, PE100 inowanzova nani. Inochinjika, haipindi simba rayo zvakanyanya, uye inogona kuchinjika zvakanyanya.majoini akasanganiswa anodzivirira kubuda kwemvurainopa kuvimbika kwepamusoro kwenguva refu. Majoini ePVC akasungirirwa kana kuti akaputirwa negasi anowanzova nzvimbo isina kusimba muhurongwa, dambudziko rinokonzerakusanganisa weldingzvinobvisa zvachose.

Kunyange zvazvo zvinhu zvose zviri zviviri zvakanaka kune mamwe mashandisirwo, musiyano wazvo mukuru unoonekwa mumamiriro ezvinhu akaoma. Chinhu chimwe chete chakanakira PE100 inzira yekubatanidza. Paunopisa fuse yepombi yeHDPE, jointi inova chidimbu chimwe chete, chakasimba chepurasitiki, chakasimba sepombi pachayo. Haigone kudonhedza mvura. Majointi ePVC, achivimba nesimende inonyungudutsa kana rabha gaskets, anounza mukana wekukundikana. Nekufamba kwenguva, kufamba kwevhu uye kuchinja kwekumanikidzwa zvinogona kukanganisa majointi aya. Kuchinjika kwePE100 kunobvumirawo kuiswa kwegomba risina gomba, izvo zvinogona kuderedza zvakanyanya nguva yekuvaka nemutengo, bhenefiti huru munzvimbo dzemaguta dzakazara vanhu. PVC, sezvo iri yakasimba, inoda kuchera kwetsika kwakavhurika kwemugero, izvo zvinokanganisa zvakanyanya uye zvinodhura.

Chii chiri musiyano uripo pakati pePE 80 nePE100?

Unoona mashoko maviri, rimwe repaipi rePE80 nerimwe rePE100. Nhamba dzacho dzinoita sedziri pedyo, asi kusarudza giredhi repasi kuchengetedza mari shoma kunogona kureva kuisa paipi isina kusimba.

Nhamba iyi inoreva Simba Rinodiwa (MRS) mushure memakore makumi mashanu. PE100 ine MRS ye10.0 MPa, nepo PE80 iri 8.0 MPa. Kuwedzera uku kwe25% musimba kunobvumira mapaipi ePE100 kuti ave nemadziro akatetepa ane chiyero chakafanana chekumanikidzwa.

IyoSimba Rinodiwa (MRS)ipfungwa inotsanangura simba renguva refu rechinhu chacho. Masayendisiti anoona izvi nekuisa pombi pasi pekumanikidzwa uye kuyera kuti zvinotora nguva yakareba sei kuti zvisashande, vozoshandisa data iroro kufanotaura simba rayo mumakore makumi mashanu ekushanda. Kana MRS yakakwira, chinhu chacho chinowedzera kusimba.

Iyi mukana wesimba re25% rePE100 kupfuura PE80 unokupa mabhenefiti maviri makuru. Chekutanga, papombi ine ukobvu hwakafanana, PE100 inogona kubata kumanikidzwa kwakanyanya. Chechipiri, uye chinonyanya kukosha pakuchengetedza mari, unogona kushandisaPombi yePE100 ine rusvingo rwakatetepakuti vawane kumanikidzwa kwakafanana nepombi yePE80 yakakora. Madziro akatetepa zvinoreva kuti hapana zvinhu zvakashandiswa, izvo zvinoita kuti pombi ive yakareruka uye isingadhuri zvakanyanya. Pombi yakareruka yakachipa kutakura uye iri nyore kubata panzvimbo yacho. Madziro akatetepa anogadzirawo dhayamita yakakura yemukati, iyo inovandudza kuyerera kwemvura uye inoderedza mitengo yekupomba mukati menguva yese yehurongwa.

Ndeipi iri nani, HDPE kana PE?

Mazwi ekuti PE neHDPE anowanzo shandiswa muhurukuro imwe chete. Izvi zvinogona kuvhiringa, zvichiita kuti ufunge kuti uri kuenzanisa zvinhu zviviri zvakasiyana zvachose iwe usingaenzanise.

Uyu mubvunzo unonetsa, sezvo HDPE (High-Density Polyethylene) iri mubvunzo chaiwomhandoyePE (Polyethylene). PE izita remhuri rakakura. Pamapaipi ekumanikidza emvura negesi, HDPE ndiyo sarudzo chaiyo uye yepamusoro nekuda kwesimba rayo uye kugara kwenguva refu.

Funga nezve "Polyethylene" (PE) sezita remhuri yeboka rese remapurasitiki. Mumhuri iyi, mune mhando dzakasiyana-siyana zvichienderana nehuwandu hwavo hwemamorekuru, izvo zvinosarudza hunhu hwavo hwepanyama.

• PE (Polyethylene):Chikamu chose.
• LDPE (Polyethylene Yakaderera):Inochinjika zvikuru, inoshandiswa pazvinhu zvakaita semabhegi epurasitiki nemafirimu. Haina kukodzera mapaipi ekumanikidza.
• HDPE (High-Density Polyethylene):Yakasimba zvikuru, yakaoma, uye yakasimba. Iyi ndiyo midziyo inoshandiswa pakushandisa mapaipi ekumanikidza anoshandiswa mukupa mvura, kugoverwa kwegasi, uye kushandiswa mumaindasitiri.

Saka, patinotaura nezvemapaipi ePE panyaya yekutarisira mvura, tinenge tichitaura nezvemapaipi eHDPE. Magiredhi atakataura kare, PE80 nePE100, ndiwo magadzirirwo chaiwo eHDPE resin. Saka, mubvunzo hausi wekuti “HDPE kana PE?” asi kuti, “Ndeipi giredhi reHDPE rakakodzera purojekiti yangu?”. Kune chero kuiswa kutsva, PE100 giredhi HDPE ndiyo sarudzo yakanakisisa.

Unogona here kusanganisa PE80 nePE100?

Unofanira kugadzirisa tambo yekare yemvura yakagadzirwa nePE80. Chinhu chako chitsva chose iPE100. Kusashanda zvakanaka kwesimbi pakati pezvinhu zviviri izvi kunogona kukonzera nyonganyonga huru yebasa.

Ehe, unogona kusundira PE80 zvakananga kuPE100. Nekuti ese ari maviri anobva mumhuri yepolyethylene, mapurasitiki awo anozobatana. Zvisinei, unofanira kushandisa maparamita ekusundira ePE80 yepasi, uye jira racho richange rakasimba sejira rePE80.

Uyu mubvunzo unokosha zvikuru pakugadzirisa nekugadzirisa. Kukwanisa kubatanidza magiredhi akasiyana mukana mukuru weHDPE. Nekuti zvese PE80 nePE100 zvakagadzirwa kubva kupolymer imwechete, maumbirwo azvo emamorekuru anoenderana uye anozobatana pamwe chete panguva yekupisa kuti pave nechisungo chakasimba, chisingaperi.

Zvisinei, pane mutemo mumwe chete wakakosha waunofanira kutevedzera:Gara uchishandisa maparamita ekuwelding (tembiricha, nguva, uye kumanikidzwa) akatarwa kune zvinhu zvemhando yepasi.PE80 nePE100 zvinogona kuva nemaitiro akasiyana ekunyunguduka, uye kushandisa marongero ePE100 kunogona kupisa zvakanyanya kana kukuvadza mugumo wepombi yePE80, zvichikonzera joini isina simba. Chinhu chechipiri chekurangarira ndechekuti sisitimu yacho yakasimba chete sekubatana kwayo kusina simba. Joini yakasungirirwa pamwe nechikamu chose chepombi zvichave nechiyero chekumanikidzwa uye hunhu hwekushanda kwepombi yePE80, kwete PE100. Kunyange zvazvo kumapurojekiti matsva tichigara tichikurudzira PE100, kuenderana uku kwakanakira kuwedzera kana kugadzirisa zvivakwa zvekare.

Mhedziso

PE100haisi kodhi chete; imhando yeHDPE inoshanda zvakanyanya. Simba rayo guru uye kuvimbika kwayo zvinoita kuti ive chiyero chemazuva ano chekuvaka mapaipi emvura akachengeteka uye anogara kwenguva refu.
