Mukuyang'ana ma specifications a paipi ndipo mukuwona ma code monga PE80 ndi PE100. Mawu aukadaulo awa ndi osokoneza, ndipo kusankha mtundu wolakwika kungawononge umphumphu wa polojekiti yanu kwa nthawi yayitali.

PE100 imatanthauza kuti chitolirochi chapangidwa kuchokera ku mbadwo waposachedwa wa High-Density Polyethylene (HDPE). "100" imatanthauza Mphamvu Yochepa Yofunikira (MRS) ya 10.0 MPa. Izi zimapangitsa kuti chikhale cholimba komanso cholimba chomwe chimalola makoma a chitoliro kukhala opyapyala pamlingo womwewo.

Ndikamalankhula ndi oyang'anira kugula zinthu monga Budi, nkhani zokhudza zinthuzi nthawi zambiri zimakambidwa. N'zosavuta kuziona ngati manambala okha, koma “PE100” ikuyimira zaka zambiri za kupita patsogolo kwa sayansi ya zinthuzi. Ndi lonjezo la mphamvu, kudalirika, komanso kugwira ntchito kwa nthawi yayitali. Kumvetsetsa tanthauzo la code yosavuta iyi ndi chinsinsi chopanga chisankho chanzeru chogula chomwe chimatsimikizira kupambana kwa njira zanu zoyendetsera madzi kwa zaka zikubwerazi. Tiyeni tifotokoze tanthauzo la giredi iyi pa ntchito zanu.

Kodi PE100 ndi yabwino kuposa PVC?

PVC ndi chinthu chodziwika bwino ndipo nthawi zambiri chimakhala ndi mtengo wotsika. Izi zimapangitsa kuti zikhale zosavuta kusankha, koma kulimba kwake komanso njira yake yolumikizirana ingayambitse mavuto mtsogolo komanso ndalama zambiri.

Pa mapayipi olowera m'madzi obisika, PE100 nthawi zambiri imakhala yabwino. Imasinthasintha mosavuta, imakana kugwedezeka kwambiri, komansomalo olumikizirana osatulutsa madziamapereka kudalirika kwabwino kwa nthawi yayitali. Malumikizidwe a PVC opangidwa ndi zosungunulira kapena zopindika nthawi zambiri amakhala malo ofooka kwambiri mu dongosolo, vuto lomwekuwotcherera kosakanikiranaamachotsa kwathunthu.

Ngakhale kuti zipangizo zonsezi ndi zabwino pa ntchito zina, kusiyana kwawo kwakukulu kumaonekera bwino pazochitika zovuta. Ubwino waukulu wa PE100 ndi njira yolumikizirana. Mukatenthetsa chitoliro cha HDPE, cholumikiziracho chimakhala pulasitiki imodzi, yolimba, yolimba ngati chitolirocho. Sichingathe kutuluka madzi. Zolumikizira za PVC, zomwe zimadalira simenti yosungunulira kapena ma gasket a rabara, zimayambitsa malo omwe angagwe. Pakapita nthawi, kuyenda kwa nthaka ndi kusintha kwa kuthamanga kwa mpweya kungawononge zolumikizirazi. Kusinthasintha kwa PE100 kumalolanso kuyika popanda ngalande, komwe kungachepetse kwambiri nthawi yomanga ndi ndalama, phindu lalikulu m'mizinda yodzaza anthu. PVC, popeza ndi yolimba, imafuna kukumba ngalande zotseguka, zomwe zimakhala zosokoneza komanso zodula.

Kodi kusiyana pakati pa PE 80 ndi PE100 ndi kotani?

Mukuwona mitengo iwiri, imodzi ya chitoliro cha PE80 ndi imodzi ya PE100. Manambalawa akuoneka ngati ofanana, koma kusankha chitoliro chotsika kuti musunge ndalama pang'ono kungatanthauze kukhazikitsa chitoliro chofooka.

Nambalayi ikutanthauza Mphamvu Yochepa Yofunikira (MRS) patatha zaka 50. PE100 ili ndi MRS ya 10.0 MPa, pomwe PE80 ndi 8.0 MPa. Kuwonjezeka kwa 25% kumeneku kwa mphamvu kumalola mapaipi a PE100 kukhala ndi makoma opyapyala kuti azitha kupanikizika mofanana.

TheMphamvu Yochepa Yofunikira (MRS)ndi mtengo womwe umafotokoza mphamvu ya nthawi yayitali ya chinthucho. Asayansi amachizindikira mwa kuyika chitoliro pansi pa kupanikizika ndikuyesa nthawi yomwe chimatenga kuti chilephereke, kenako nkugwiritsa ntchito detayo kulosera mphamvu yake pa moyo wautumiki wa zaka 50. MRS ikakwera, chinthucho chimakhala cholimba.

Ubwino wa 25% wa mphamvu ya PE100 kuposa PE80 ukukupatsani maubwino awiri akuluakulu. Choyamba, pa chitoliro chokhala ndi makulidwe ofanana, PE100 imatha kuthana ndi kupanikizika kwakukulu. Chachiwiri, komanso chofunika kwambiri kuti musunge ndalama, mutha kugwiritsa ntchitoChitoliro cha PE100 chokhala ndi khoma lopyapyalakuti akwaniritse kupanikizika komweko monga chitoliro chokhuthala cha PE80. Khoma lochepa limatanthauza kuti sipagwiritsidwa ntchito zinthu zopangira zambiri, zomwe zimapangitsa kuti chitolirocho chikhale chopepuka komanso chotsika mtengo. Chitoliro chopepuka ndi chotsika mtengo kunyamula komanso chosavuta kuchigwira pamalopo. Khoma lochepa limapanganso kukula kwamkati, komwe kumathandizira kuyenda kwa madzi ndikuchepetsa ndalama zopopera nthawi yonse ya dongosololi.

Ndi chiyani chabwino, HDPE kapena PE?

Mawu akuti PE ndi HDPE nthawi zambiri amagwiritsidwa ntchito mu zokambirana zomwezo. Izi zitha kukhala zosokoneza, zomwe zingakupangitseni kuganiza kuti mukuyerekeza zinthu ziwiri zosiyana kwambiri pomwe simukuyerekeza.

Funso ili ndi lovuta, chifukwa HDPE (High-Density Polyethylene) ndi chinthu chapadera.mtunduya PE (Polyethylene). PE ndi dzina lalikulu la banja. Pa mapaipi opondereza madzi ndi gasi, HDPE ndiye chisankho choyenera komanso chapamwamba chifukwa cha mphamvu zake komanso kulimba kwake.

Ganizirani za “Polyethylene” (PE) ngati dzina la banja lonse la mapulasitiki. M'banjali, pali mitundu yosiyanasiyana kutengera kuchuluka kwa mamolekyu awo, zomwe zimatsimikizira mawonekedwe awo enieni.

• PE (Polyethylene):Gulu lonse.
• LDPE (Polyethylene Yochepa Kwambiri):Yosinthasintha kwambiri, imagwiritsidwa ntchito pazinthu monga matumba apulasitiki ndi mafilimu. Siyoyenera mapaipi opondereza.
• HDPE (Polyethylene Yokhala ndi Kachulukidwe Kakakulu):Yamphamvu kwambiri, yolimba, komanso yolimba. Ichi ndi chipangizo chokhazikika cha mapaipi opanikizika omwe amagwiritsidwa ntchito popereka madzi, kugawa gasi, komanso ntchito zamafakitale.

Kotero, tikamalankhula za chitoliro cha PE pankhani yosamalira madzi, nthawi zambiri timakhala tikulankhula za chitoliro cha HDPE. Magiredi omwe tidakambirana kale, PE80 ndi PE100, ndi magulu enieni a magwiridwe antchito a utomoni wa HDPE. Chifukwa chake, funso si "HDPE kapena PE?" koma m'malo mwake, "Ndi mtundu uti wa HDPE womwe uli woyenera pulojekiti yanga?". Pa kukhazikitsa kulikonse kwatsopano, PE100 grade HDPE ndiye chisankho chabwino kwambiri.

Kodi mungathe kulumikiza PE80 ku PE100?

Muyenera kukonza chingwe chakale cha madzi chopangidwa ndi PE80. Chida chanu chatsopano ndi PE100. Kulephera kwa weld pakati pa zipangizo ziwirizi kungayambitse chisokonezo chachikulu pa ntchito.

Inde, mutha kulumikiza PE80 mwachindunji ku PE100. Popeza onsewa ndi a m'banja la polyethylene, mapulasitiki awo adzalumikizana. Komabe, muyenera kugwiritsa ntchito njira zolumikizirana za PE80 yotsika, ndipo cholumikiziracho chidzakhala cholimba ngati cholumikizira cha PE80.

Funso ili ndi lofunika kwambiri pa ntchito yokonza ndi kukonza. Kutha kulumikizana ndi mitundu yosiyanasiyana ndi mwayi waukulu wa HDPE. Chifukwa PE80 ndi PE100 zonse zimapangidwa kuchokera ku polima imodzi yoyambira, kapangidwe ka mamolekyu awo ndi kogwirizana ndipo zimalumikizana panthawi yotenthetsera kutentha kuti apange mgwirizano wolimba komanso wokhazikika.

Komabe, pali lamulo limodzi lofunika kwambiri lomwe muyenera kutsatira:nthawi zonse gwiritsani ntchito magawo olumikizira (kutentha, nthawi, ndi kupanikizika) omwe afotokozedwa pazinthu zotsika.PE80 ndi PE100 zimatha kukhala ndi machitidwe osiyana pang'ono osungunula, ndipo kugwiritsa ntchito makonda a PE100 kumatha kutentha kwambiri kapena kuwononga mapeto a chitoliro cha PE80, zomwe zimapangitsa kuti cholumikiziracho chikhale chofooka. Chinthu chachiwiri choyenera kukumbukira ndichakuti dongosololi limakhala lolimba ngati cholumikizira chake chofooka kwambiri. Cholumikiziracho cholumikizidwa ndi gawo lonse la chitolirocho chidzakhala ndi kupanikizika ndi magwiridwe antchito a chitoliro cha PE80, osati PE100. Ngakhale kuti pa ntchito zatsopano nthawi zonse timalimbikitsa PE100, kugwirizana kumeneku ndi kwabwino kwambiri pakukulitsa kapena kukonza zomangamanga zakale.

Mapeto

PE100si code yokha; ndi giredi ya HDPE yogwira ntchito bwino kwambiri. Mphamvu yake yapamwamba komanso kudalirika kwake zimapangitsa kuti ikhale muyezo wamakono womangira mapaipi amadzi otetezeka komanso okhalitsa.
