PE bututuyanzu suna kasuwa, kuma sun riga sun zama samfura da aka saba da su, musamman waɗanda ke cikin masana'antar.Lokacin da aka ambaci bututun PE, nan da nan suna tunanin juriya na lalacewa, juriya na matsa lamba, juriya na lalata da kuma tsawon rayuwar sabis.Akwai bututun PE da yawa.Nau'in, an raba kayan masara zuwa cikin nau'ikan, da aka samar da ingantaccen bayani, menene bambanci tsakanin ƙa'idodin bututun pe80 da pe100?
Kayan PE shine polyethylene, wanda shine nau'in kayan filastik iri-iri.Abu ne na polymer wanda aka haɗa daga polyethylene.
Ainihin kasu kashi biyu: ƙananan ƙarancin polyethylene LDPE (ƙananan ƙarfi);high yawa polyethylene HDPE.An raba kayan PE zuwa maki biyar bisa ga ƙa'idar haɗin kai ta duniya: PE32 grade, PE40 grade, PE63 grade, PE80 grade and PE100 grade.
Samar da bututun PE don bututun samar da ruwa shine polyethylene mai girma (HDPE), kuma makinsa sune PE80 da PE100 (bisa ga taƙaitaccen Ƙarfin da ake buƙata, MRS).MRS na PE80 ya kai 8MPa;MRS na PE100 ya kai 10MPa.MRS tana nufin ƙarfin damuwa na bututun hoop (ƙimar ƙididdigewa da aka gwada bisa ga ƙa'idodin ƙasashen duniya).
PE80 (8.00 ~ 9.99Mpa) babban batch ne tare da abun ciki na antimony trioxide na 80% akan polyethylene substrate, wanda za'a iya amfani dashi galibi wajen yin fim da yin fim a lokaci guda.Babban ƙwanƙwasa ce mai ƙura mara ƙura wanda ya fi aminci a samarwa fiye da foda na gargajiya, mai sauƙin sarrafa adadin, kuma ana ɗaukarsa a matsayin babban maƙasudi na gabaɗaya, wanda ke gudana kyauta a sigar granular.
PE100 (10.00 ~ 11.19Mpa) shine adadin maki da aka samu ta hanyar zagaye mafi ƙarancin ƙarfin da ake buƙata (MRS) na albarkatun kasa na polyethylene.A cewar GB / T18252, da hydrostatic ƙarfi na abu m 20 ℃, 50 shekaru da kuma annabta yiwuwa na 97.5% ne m bisa GB / T18252.σLPL, canza MRS, kuma ninka MRS ta 10 don samun lambar rarraba kayan.

1. Menene PE100 polyethylene bututu?
An gane haɓakar kayan bututun polyethylene kamar yadda aka raba su zuwa tsararraki uku, wato matakan haɓaka uku:
Ƙarni na farko, ƙananan polyethylene da kuma "nau'i na ɗaya" polyethylene mai girma, suna da mummunan aiki kuma suna daidai da kayan bututun polyethylene na yanzu a ƙasa PE63.
ƙarni na biyu, wanda ya bayyana a cikin 1960s, wani matsakaici-yawa polyethylene bututu abu tare da dogon lokacin da hydrostatic ƙarfi da tsaga juriya, wanda yanzu ake kira PE80 sa polyethylene bututu abu.
Ƙarni na uku, wanda ya bayyana a cikin 1980s, ana kiransa ƙarni na uku polyethylene bututu na musamman PE100.PE100 yana nufin cewa a 20 ° C, bututun polyethylene har yanzu yana iya kula da mafi ƙarancin ƙarfin da ake buƙata na MRS na 10MPa bayan shekaru 50, kuma yana da kyakkyawan juriya ga saurin fashewa.
2. Menene babban amfanin PE100 polyethylene bututu?
PE100 yana da duk kyawawan kaddarorin polyethylene, kuma kayan aikin injinsa sun inganta sosai, wanda ya sa PE100 yana da fa'idodi na musamman da yawa kuma ana amfani dashi a cikin ƙarin filayen.
2.1 Ƙarfin juriya mai ƙarfi
Saboda resin PE100 yana da ƙaramin ƙarfin da ake buƙata na 10MPa, yana da ƙarfi fiye da sauran polyethylene, kuma ana iya ɗaukar gas da ruwa a ƙarƙashin babban matsa lamba;
2.2 bangon bakin ciki
A ƙarƙashin matsin aiki na yau da kullun, bangon bututu da aka yi da kayan PE100 na iya zama bakin ciki sosai.Don manyan bututun ruwa na diamita, yin amfani da bututu na bakin ciki na iya adana kayan aiki da fadada yanki na yanki na yanki na bututu, don haka ƙara ƙarfin jigilar bututun.Idan ƙarfin isarwa ya kasance akai-akai, haɓakar sashin giciye yana haifar da raguwa a cikin ƙimar kwararar ruwa, ta yadda za'a iya fahimtar isar da isar da wutar lantarki ta ƙaramin famfo, amma ana adana farashin.
2.3 Matsayin aminci mafi girma
Idan bututu yana da girman ko kuma an ƙayyade matsi na aiki, ƙimar aminci wanda PE100 zai iya tabbatarwa yana da garantin a cikin jerin bututun polyethylene daban-daban na yau.
2.4 Babban taurin
PE100 abu yana da wani na roba modulus na 1250MPa, wanda shi ne mafi girma fiye da 950MPa na daidaitattun HDPE guduro, wanda ya sa PE100 bututu da mafi girma zobe stiffness.
3. Mechanical Properties na PE100 guduro
3.1 Ƙarfi Mai Dorewa
Ƙarfin ɗorewa an ƙaddara ta hanyar gwada gwajin layukan a yanayin zafi daban-daban (20°C, 40°C, 60°C da 80°C).A 20 ℃, PE100 guduro iya kula da ƙarfi na 10MPa bayan shekaru 50, (PE80 ne 8.0MPa).
3.2 Kyakkyawan juriya mai tsauri
PE100 polyethylene bututu na musamman abu yana da kyau juriya ga danniya fatattaka, jinkirta abin da ya faru na danniya fatattaka (> 10000 hours), kuma shi za a iya ko da a jinkirta fiye da shekaru 100 a karkashin yanayin 20 ℃.
3.3 Mahimmancin juriya ga saurin fashewar girma
Bukatar ikon yin tsayayya da saurin haɓakar fashe yana iyakance amfani da bututun polyethylene na gargajiya: don gas, iyakar matsa lamba shine 0.4MPa, kuma don isar da ruwa, shine 1.0MPa.Saboda iyawar PE100 mai ban mamaki don tsayayya da saurin haɓakar fashe, ƙimar matsin lamba a cikin hanyar sadarwar iskar gas ta ƙaru zuwa 1.0MPa (an yi amfani da 1.2MPa a Rasha da 1.6MPa a cikin hanyar sadarwar ruwa).A cikin kalma, aikace-aikacen PE100 polyethylene abu a cikin bututun zai tabbatar da cewa sigogin aikin na bututun samar da ruwa na pe100 a cikin hanyar sadarwar bututu sun fi aminci, mafi tattalin arziki kuma suna da tsawon rayuwar sabis.
