Uri kuedza kutsvaga mapaipi woona "poly pipe" uye "HDPE pipe" zvichishandiswa mumashoko ekuratidza kuti zvinhu zviri mudata. Izvi zvinogadzira kusava nechokwadi, zvichiita kuti unetseke kana uri kuenzanisa zvigadzirwa zvakanaka kana kuti usina ruzivo rwakakosha.

Hapana musiyano wekushanda. "Poly pipe" izita remadunhurirwa rinozivikanwa, risiri repamutemo remapaipi eHDPE (High-Density Polyethylene). Kana mumwe munhu ari muindasitiri yemvura akati "poly pipe," anenge achireva mapaipi eHDPE anoshandiswa pakushandisa simba remagetsi semvura negasi.

Ndakanga ndiri pavhidhiyo ndichifonera nemutengesi mutsva muSurabaya, uye akaramba achibvunza nezvemitengo yedu ye "poly pipe" zvichienzaniswa nemitengo yedu ye "HDPE". Ndakamisa hurukuro ndikatsanangura kuti zvakafanana. Chiso chake chakaratidza kusununguka ipapo ipapo. Aifunga kuti akanga asisina chimwe chinhu chehunyanzvi. Iyi ipfungwa inowanzo vhiringidzika. "Poly" ingori izwi remutauro weslang riri nyore kutaura, nepo "HDPE" iri chinhu cheinjiniya chaicho. Funga nezvazvo seizvi: ungakumbira "Coke," asi chigadzirwa chacho pachacho iCoca-Cola. Kune chero chinangwa chebasa, tiri kutaura nezveHDPE, uye kazhinji giredhi rePE100.

Unogona kushandisa PVC fittings paHDPE pombi here?

Une zvinhu zvakawanda zvePVC uye pombi yeHDPE inoda kubatana. Kushandisa zvaunazvo kwaizokurumidza uye kwakachipa, asi zvakachengeteka here kana kuti zvinokwanisika?

Kwete, haugone kushandisa PVC fittings dzakajairwa paHDPE pombi. Zvinhu zvacho hazvienderane nemakemikari uye zvinoda nzira dzakasiyana zvachose dzekubatanidza. Kuedza kunamira PVC fitting paHDPE pombi kunoita kuti pave nejointi inovimbiswa kuti ichakundikana kana paine kumanikidzwa.

Iyi inyaya yakakosha yekuchengetedzeka uye kuvimbika. PVC neHDPE mhuri mbiri dzakasiyana zvachose dzepurasitiki. Zvigadziko zvePVC zvinobatanidzwa uchishandisa simende inonyungudutsa, inova mhando yeglue yemakemikari. Chigadziko ichi chinoshanda nekunyorovesa pamusoro pepombi yePVC nemakemikari, zvichivabvumira kubatana pamwe chete sezvo chigadziko chinopera. HDPE, kune rumwe rutivi, ipolyolefin. Ine pamusoro une wakisi, usina simba uyo pasina glue kana simende inonyungudutsa inogona kubatana nayo zvakanaka. Kana ukaedza kuzvinamira, waizogadzira chisimbiso chisina kusimba, chenguva pfupi chinoputika kana tambo yadzvanywa. Nzira chete chaiyo yekubatanidza sisitimu yePVC kune sisitimu yeHDPE ndeyekushandisa chigadziko chakakosha chekuchinja, sengeadapta yeflangekumativi ese akabatana pamwe chete, kana kuti kubatanidza kwakagadzirirwa kubatanidza zvinhu zviviri zvakasiyana.

Unonama here pombi yeHDPE?

Unofanira kubatanidza zvidimbu zviviri zvepaipi yeHDPE. NePVC, maitiro acho ari nyore: isa primer neglue. Izvi zvinoita kuti uzvibvunze kana paine namatidziro yakafanana neyapaipi yeHDPE.

Kwete, haumboshandisi guruu papombi yeHDPE. Kugadzirwa kwemakemikari kweHDPE kunoita kuti zvisaita kuti manamatisi agadzire chisungo chinogara kwenguva refu, chakasimba. Nzira chete yakakodzera yekubatanidza HDPE ndeyekubatanidza kupisa kwemuviri, uko kunonyungudutsa purasitiki pachayo kuti igadzire joinhi.

Chikonzero chinoita kuti urege kunamira HDPE imhaka yesainzi yayo yezvinhu. HDPE inekuramba kwakanyanya kumakemikari uye zvinonyungudutsa, inova imwe yezvakanakira zvayo zvikuru. Hunhu humwe chete uhwu hunoreva kuti manamati emakemikari, se simende inonyungudutsa inoshandiswa paPVC, haashande. Haagoni "kuruma" pamusoro pepurasitiki kuti agadzire weld. Kuedza kuwana "glue" yeHDPE chikanganiso chinowanzoitika kune mapoka matsva kune zvinhu izvi. Nzira chaiyo uye yega inogamuchirwa neindasitiri yekugadzira joint inogara iripo ndeye heat fusion. Maitiro aya anoshandisa chishandiso chekupisa chakasarudzika kunyungudutsa pamusoro pemapaipi kana fittings ari kubatanidzwa. Kana angonyunguduka, anosundwa pamwe chete uye anobatwa pasi pekumanikidzwa. Sezvo purasitiki ichitonhora, inobatanidzwa kuita chidimbu chimwe chete, chisina musono. Joint inobuda haisi chisimbiso chete; i weld yakazara ine monolithic yakasimba, kana kuti yakasimba, kupfuura pombi yekutanga pachayo.

Ndeipi nzira yakanakisisa yekubatana neHDPE?

Uchiziva kuti haugone kushandisa guruu, unofanirwa kunzwisisa nzira chaiyo yehunyanzvi. Kusarudza nzira chaiyo kwakakosha kuti uve nechokwadi chekuti pombi yako yakasimba, haidonhe mvura, uye inogara kwemakumi emakore.

Nzira yakanakisisa yekubatanidza HDPE ndeyekubatanidza kupisa. Maitiro aya anogadzira joini inogara iripo, ine simba rakafanana nepombi pachayo. Nzira mbiri huru ndeidzikusangana kwemagaroyemapaipi makuru uyekusangana kwemasokisiyemapaipi madiki uye zvinosungirirwa.

Kubatanidza kupisa ndiyo nzira yakanakisisa yeHDPE nekuti inobvisa nzvimbo inowanzo kundikana mupaipi chero ipi zvayo: joini. Panzvimbo pekuvimba nechimwe chinhu chakasiyana senge gasket kana guruu, inoshandura magumo maviri kuita chidimbu chimwe chete chakasimba. Nzira chaiyo inoenderana nehukuru hwepaipi.

Kusanganiswa Kwemagaro

1. Magumo maviri emapaipi anosungirirwa mumuchina unovimbisa kurongeka kwakakwana.
2. Muchina wekucheka wakakosha unotarisa magumo, zvichiita kuti achene zvakakwana uye aenderane.
3. Chidziyo chekupisa chinodzora tembiricha chinoiswa pakati pemagumo, chichinyungudutsa kusvika pakadzika kwakati.
4. Purati yekupisa inobviswa, uye magumo akanyungudutswa anodzvinyirirwa pamwe chete nekumanikidzwa kwakadzorwa, zvichiita kuti pave nekunamira.

Kusanganiswa kweSocket

1. Chishandiso chekudziisa chine misoro yechirume neyechikadzi inoenderana chinodziisa kunze kwepombi nemukati mechinhu chinoiswa panguva imwe chete.
2. Kana changodziiswa, chishandiso chinobviswa, uye pombi inobva yangosundirwa musokisi yechinhu chinoiswa.
3. Zvikamu zvacho zvinochengetwa kwenguva pfupi yekutonhodza, zvichibvumira mapurasitiki kubatana zvachose.

Ndeipi nguva yekurarama kwepombi yeHDPE?

Uri kuisa mari yakawanda muzvivakwa zvako. Unofanira kuva nechokwadi chekuti zvinhu zvaunosarudza hazvizodi kugadziriswa kana kutsiviwa nemari yakawanda mumakore mashoma chete.

Pombi yeHDPE ine hupenyu hwekugadzira hunogara kwemakore makumi mashanu, asi fungidziro chaiyo uye zvidzidzo zvinoratidza kuti inogona kugara kwemakore zana kana kupfuura. Kugara kwayo kwenguva refu kunobva mukuramba kwayo ngura, kurwiswa nemakemikari, uye kuneta kwemuviri, zvichiita kuti ive nemutengo wakaderera wekuva nayo.

Kugara kwenguva refu kwepaipi yeHDPE hakusi kungotaura chete; imhedzisiro yehunhu hwayo hwezvinhu zvikuru. Izvi zvinoita kuti ive mari yenguva refu ine uchenjeri, inova chinhu chakakosha pakuongorora kwemutengi wekutenga. Pane zvikonzero zvakawanda zvinoita kuti igare kwenguva yakareba kudai:

• Hazvina Chemical Inert:HDPE haipedzi ngura kana kuora semapaipi esimbi. Inodzivirirawo zvakanyanya makemikari, maasidhi, uye maalkali anowanikwa muvhu nemvura, saka madziro epaipi haaparare nekufamba kwenguva.
• Inodzivirira kuneta:HDPE chinhu chinochinjika. Izvi zvinoita kuti ikwanise kunyudza kumanikidzwa, kudedera, uye kufamba kwepasi izvo zvinogona kukonzera kuti mapaipi akaomarara akadai sePVC kana simbi atsemuke okundikana.
• Inodzivirira Kukwenya:Chigadzirwa chacho chakasimba zvikuru uye chinogara zvakanaka pazvinhu zvinokwesha zvinogona kunge zvichiyerera mukati mepombi, zvakaita sejecha kana grit, izvo zvinowanikwa mune dzimwe nzvimbo dzemvura.
• Majoini Asingabudisi Mvura:Sezvatakakurukura, majoini akabatana nekupisa akasimba sepombi. Izvi zvinobvisa kurasikirwa nemvura kubva kumajoini anodonhedza mvura, iro riri dambudziko guru kwenguva refu nehurongwa hwekare hunoshandisa majoini ane gasketed kana bell-and-spigot.

Mhedziso

Pombi yePoly ingori zita remadunhurirwa reHDPE. Chinhu chakanaka kwazvo chakabatanidzwa nekubatana kwekupisa, kwete guruu, chinopa hupenyu hwekushanda hunosvika makore zana kana kupfuura.
