Uri kuedza kusarudza pombi yakakodzera. Makodhi akaita sePE 80 nePE 100 anovhiringidza, uye kusarudza zvisiri izvo kunogona kukonzera kutadza kushanda kwesystem uye kugadzirisa kunodhura.

PE 100 ndiyo chizvarwa chechangobva kugadzirwa cheHigh-Density Polyethylene (HDPE). Iyo "100″ zvinoreva kuti ine Minimum Required Strength (MRS) ye10.0 MPa, zvichiita kuti ive yakasimba kupfuura zvinhu zvekare. Izvi zvinobvumira mapaipi ane madziro akatetepa anokwanisa kushivirira kumanikidzwa kwakanyanya.

Pandinotaura nevatungamiriri vekutenga vakaita saBudi, mubvunzo wekuti “PE 80 vs. PE 100"Zvinogara zvichibuda. Zvinoita semusiyano mudiki, asi nhamba iyoyo ndiyo kiyi yekushanda kwezvinhu. Inomiririra makumi emakore ekugadzira makemikari nekuvandudza. Kunzwisisa kupatsanura uku kuri nyore ndiyo nhanho yekutanga yekusarudza pombi yakavimbika uye inodhura zvishoma kune chero purojekiti. Ngationgororei zvinorehwa nenhamba idzodzo kubhizinesi renyu.

Ndeupi musiyano uripo pakati pePE 80 nePE 100?

Uri kuenzanisa mitengo uye ona mapaipi ePE 80 nePE 100. PE 80 yakachipa, asi yakasimba zvakakwana here? Kusarudza zvichibva pamutengo chete injodzi huru.

PE 100 ine Simba Rinodiwa (MRS) re10.0 MPa, nepo PE 80′s iri 8.0 MPa. Izvi zvinoita kuti PE 100 isimbe, zvichiita kuti ikwanise kubata kumanikidzwa kwakanyanya. Pakumanikidzwa kwakafanana, pombi yePE 100 inogona kuva nemadziro akatetepa, zvichichengetedza zvinhu uye huremu.

Nhamba iri muzita ndiyo inonyanya kukosha kunzwisisa. Harisi izwi rekushambadzira chete; asi iboka resainzi rakavakirwa pasimba renguva refu.Simba Rinodiwa (MRS)Zvinoonekwa nekuyedza chinhu ichi chiri pasi pekumanikidzwa kwenguva yakareba kuti zvifanotaura mashandiro acho kwemakore anopfuura makumi mashanu.

• PE 80:Ine MRS ye8.0 MPa. Iyi ndiyo yaive tsika kwemakore mazhinji uye ichiri chinhu chakanaka.
• PE 100:Ine MRS ye10.0 MPa. Uku kuwedzera kwesimba shoma ne25% kupfuura PE 80.

Simba iri rekuwedzera rinokupa mabhenefiti maviri makuru. Chekutanga, unogona kushandisa pombi yePE 100 kubata kumanikidzwa kwakanyanya kupfuura pombi yePE 80 ine ukobvu hwakafanana hwemadziro. Chechipiri, uye kazhinji, unogona kushandisa pombi yePE 100 ine madziro akatetepa kuti uwane chiyero chakafanana chekumanikidzwa. Rusvingo rwakatetepa runoreva zvinhu zvishoma, zvichiita kuti pombi ive yakareruka uye kazhinji isingadhuri. Zvinopawo pombi dhayamita yakakura yemukati, izvo zvinovandudza hunhu hwekuyerera kwemvura.

Chii chinonzi PE 100 grade papombi yeHDPE?

Unoona "PE 100 Grade" papepa remagadzirirwo. Zviri nyore kufuratira seimwe izwi rehunyanzvi, asi giredhi iri rinokanganisa zvakananga mashandiro epombi uye kuvimbika kwenguva refu.

Pombi ye "PE 100 grade" HDPE ine chitupa chekuti yakagadzirwa nePE 100 resin inoshanda zvakanaka. Izvi zvinovimbisa simba rayo guru (10.0 MPa MRS), kumanikidzwa kwayo kwakanyanya, uye kuramba kukura zvishoma nezvishoma, zvichiita kuti igare kwenguva refu.

Kana ukaona "Giredhi rePE 100"," ivimbiso yemhando yepamusoro uye mashandiro. Zvinoreva kuti pombi iyi haina kungogadzirwa nepurasitiki chete; yakagadzirwa neresin yakagadzirwa zvakananga uye yakaedzwa kuti isvike padanho repamusoro. Kunze kwesimba rayo rakakwirira, mhando iyi ine zvimwe zvakanakira zvakakosha. Chimwe chezvinhu zvinonyanya kukosha ndechekusagona kwayo kuidzivirira zvakanyanya.Kukura Kwekukanganisika Kunonoka (SCG). Panguva yekuisa, mapaipi anogona kukwenywa kana kukuvadzwa zvishoma. Muzvinhu zvisina kunaka, kusakwana uku kudiki kunogona kukura zvishoma nezvishoma kuita mutswe mukuru mumakore ekushanda kwesimba, zvichizopedzisira zvaita kuti paipi iparare. PE 100 yakagadzirirwa kudzivirira izvi, zvichiita kuti igare kwenguva refu uye iregerere mamiriro chaiwo ekuisa. Ndiyo sarudzo yakakodzera mapaipi achavigwa uye anofanira kugara kwemakumi emakore pasina matambudziko.

Sei modulus yekusimba kwePE 100 ichikosha?

Unoverenga "modulus of elasticity" papepa reruzivo wobva watarisa. Izwi iri rehunyanzvi rinoita serisina basa, asi rinotsanangura chimwe chezvakanakira zvikuru zvechinhu ichi.

Modulus yekusimba inoyera kuomarara. PE 100 ine modulus yakaderera, zvichiita kuti igone kuchinjika zvakanyanya. Izvi zvinobvumira pombi kukotama ichitenderedza zvipingamupinyi, kupihwa mu coil refu, uye kushandiswa munzira dzekuisa pasina trench, izvo zvinoderedza zvakanyanya mari yekuisa.

Zvakakosha kuti usavhiringidze kusimba nekuomarara. Chinhu chakaita segirazi chakaomarara, asi hachina kusimba kana charova nekuti hachina kusimba. PE 100 yakasimba uye inochinjika-chinjika. Kuchinjika uku mukana mukuru panguva yekuisa. Kune dhayamita diki, tinogona kupa pombi yacho mumakona marefu e100 metres kana kupfuura. Izvi zvinoreva kuti majoini mashoma anodiwa, izvo zvinochengetedza nguva yakawanda uye zvinobvisa nzvimbo dzisina kusimba dzinogona kuitika. Kune dhayamita hombe, kuchinjika uku kunobvumira pombi kushandiswa munzira dzemazuva ano dzekuisa sengeKuboorera Kwakanangana Nekutungamirira (HDD)Izvi zvinoita kuti vanoisa pombi vakweve pasi pevhu vasina kuchera mugero murefu, unoparadza. Izvi zvakanaka pakuyambuka nzizi, migwagwa, kana nzvimbo dzinokanganisa nharaunda. Munyika yakaita seIndonesia ine nzvimbo dzakasiyana-siyana, kuchinjika uku kunogona kuchengetedza mari yakawanda pamari yekuisa kana tichienzanisa nemapombi akaomarara.

Ko PE 100 ndiyo sarudzo iri nani pane PVC here?

PVC ipombi inoshandiswa zvakanyanya, uye pamwe unoiziva zvakanyanya. Inowanzova nemutengo wakaderera wekutanga, saka sei uchifanira kuchinja kuenda kuPE 100?

PE 100 inowanzo kuve nani kune mains akavigwa. Zvakanakira zvayo zvikuru kupfuura PVC ndezvekuti inochinjika, inodzivirira kukuvadzwa zvakanyanya, uye majoini akasanganiswa anodzivirira kubuda kwemvura. Majoini ePVC akasungirirwa kana kuti akaputirwa negasi anowanzova asina simba zvakanyanya musystem, dambudziko iro fusion welding inobvisa zvachose.

Kunyange zvazvo zvinhu zvose zvakanaka, zvakagadzirirwa simba rakasiyana. Chinhu chimwe chete chikuru chinobatsira chePE 100 inzira yekubatanidza.

Majoini ndiwo akakosha. Kana uchipisa fuse yepombi yePE 100, joini inova chidimbu chimwe chete, chinoenderera mberi chepurasitiki. Haigone kudonha. NePVC, unoshandisa weld yemakemikari inonyungudutsa kana rabha gasket. Majoini aya kazhinji ndiwo nzvimbo yekutanga iyo kudonha kunoitika kwenguva refu. Kune chero pombi yakavigwa uko kugadzirisa kwaizodhura uye kwakaoma, joini yePE 100 isingadonhedze mvura inoita kuti ive mari yakanaka kwenguva refu.

Mhedziso

PE 100 inopfuura nhamba chete. Simba rayo guru, kuchinjika kwayo, uye majoini ayo akabatana asingadonhedze mvura zvinoita kuti ive sarudzo yemazuva ano uye yakavimbika kune chero chirongwa chakakosha chekugadzira mapaipi kwenguva refu.
