Tanthauzo la HDPE
HDPA ndi mawu omwe nthawi zambiri amagwiritsidwa ntchito kutanthauza kuchuluka kwa polyethylene. Timalankhulanso za pe, ldi kapena pe-hd. Polyethylene ndi zinthu za thermoplactic zomwe zili mbali ya banja la pulasitiki.
Pali mitundu yosiyanasiyana ya polythylenes. Kusiyana kumeneku kumafotokozedwa ndi njira zopangira zomwe zingachititse zosiyana. Tikulankhula za Polyethylene:
• Kuchulukitsa kotsika (ldpe)
• Kuchulukitsa kwambiri (hdpe)
• Kuchulukitsa kwapakati (pemd).
Kuphatikiza apo, pali mitundu ina ya polyethylene: chlorinated (pe-c), ndi kulemera kwambiri molemphuka.
Zidule zonsezi ndi mitundu ya zinthu zamitundu zimakhazikika pansi pa AEGIS za NF ENO 1043-1
HDPE ndiyotsatira chifukwa cha kuchuluka kwa kachulukidwe kakang'ono: Kuchulukitsa kwambiri polyethylene. Ndi izi, titha kupanga zoseweretsa za ana, matumba apulasitiki, komanso mapaipi omwe amagwiritsidwa ntchito ponyamula madzi!
Phukusi la HDPE limapangidwa kuchokera ku synthesis. Chifukwa chopanga, HDPE imakhudzanso zinthu zosiyanasiyana:
• Kulima
• Steam sharking
• polymerization
• Kukula
Pambuyo kusintha kumeneku, chinthucho ndi cha mkaka choyera, chosinthika. Ndiye kuti ndizosavuta kukhala ndi utoto kapena utoto.
HDPA imagwiritsa ntchito mafakitale
Chifukwa cha mikhalidwe yake ndi zabwino zake, hdpe imagwiritsidwa ntchito m'malo ambiri a mafakitale.
Amapezeka kulikonse kuzungulira ife m'moyo wathu watsiku ndi tsiku. Nawa zitsanzo:
Kupanga mabotolo apulasitiki ndi phukusi la pulasitiki
HDPE imadziwika bwino m'makampani azakudya, makamaka popanga mabotolo apulasitiki.
Ndi chidebe chabwino kwambiri cha chakudya kapena zakumwa kapena popanga zisoti zamabotolo. Palibe chiopsezo chowonongeka monga momwe pakhoza kukhala ndi galasi.
Kuphatikiza apo, phukusi la pulasitiki la HDPE lili ndi mwayi waukulu wokubwezerani.
Kuposa makampani azakudya, hdpe amapezeka m'malo ena a mafakitale onse:
• Kupanga zoseweretsa,
• Mabizinesi apulasitiki a ma 1
• mabokosi osungira
• Popanga maatoe-kayaks
• Kupanga zida za Beocton
• Ndi ena ambiri!
HDPA mu mafakitale ndi mankhwala
Mafakitale a mankhwala ndi mankhwala opangira mankhwala amagwiritsa ntchito HDPPA chifukwa imagwira ntchito zosagwirizana. Amanenedwa kuti ndi njira ya makilo.
Chifukwa chake, lidzakhala chidebe:
• kwa shampoos
• Zinthu zapakhomo zogwiritsidwa ntchito ndi chisamaliro
• kutsuka
• mafuta a injini
Amagwiritsidwanso ntchito ngati mabotolo amankhwala.
Kuphatikiza apo, tikuwona kuti mabotolo opangidwa ku Polypropylene ali ndi mphamvu kwambiri pakusunga zinthu zawo pomwe ali achikuda kapena kuphatikizidwa.
Hdpe ya opanga zomanga ndi zochita zamadzimadzi
Pomaliza, limodzi la madera ena omwe amagwiritsa ntchito HDPEPE ndiye gawo la poiping komanso gawo lomanga nthawi zambiri.
Ukhondo kapena akatswiri omanga amagwiritsa ntchito kuti amange ndikukhazikitsa mapaipi omwe adzagwiritsidwe ntchito kuyendetsa madzi (madzi, gasi).
Kuyambira m'ma 1950s, chitoliro cha HDPPA chalowa m'malo. Kutsogolera papang'onopang'ono kunali koletsedwa pang'onopang'ono chifukwa chosowa madzi.
Kuchulukitsa kwa polyethylene (HDPE) chitoliro, ndi chitoliro chomwe chimapangitsa kuti zitsimikizidwe kuti madzi akumwa: ndi amodzi mwa mapaipi amadzi akumwa kwambiri awa.
HDPPA imapereka mwayi wokana kutentha kwa madzi mu chitoliro, mosiyana ndi LLDPE (Matanthauzidwe a Polyethylene). Kuti mugawire madzi otentha oposa 60 °
HDP imapangitsanso kuti ithe kunyamula mpweya ndi chubu, kupanga ma ducts kapena mpweya wabwino mnyumba.
Ubwino ndi zovuta zokhudzana ndi HDPPA pa malo opanga mafakitale
Chifukwa chiyani HDPPA imagwiritsidwa ntchito mosavuta pamasamba opanga mafakitale? Ndipo m'malo mwake, kodi ndi ziti zomwe zingakhale zovuta zina?
Ubwino wa HDPE ngati nkhani
HDPA ndi zinthu zomwe zimakhala ndi zofunikira zingapo zomwe zimapangitsa kuti azigwiritsa ntchito m'mafakitale kapena machitidwe a madzi akupukutira.
HDPE ndi nthano yotsika mtengo kwa mtundu wachitsanzo chabwino. Zimakhala zolimba kwambiri (zosagwedezeka) pomwe kuwunika.
Itha kupirira michere yosiyanasiyana yopanga (yotsika komanso kutentha kwambiri: Kuchokera -30 ° C kwa + Ndipo pamapeto pake ndizolimbana ndi zosungunulira zomwe zingawonongeke. sag kapena kusintha.
Tiyeni tisanthule zina zabwino:
HDPA: Zinthu zosavuta
Chifukwa cha njira zopangira zomwe zimapanga hdpe, hdpe sagwirizana ndi kutentha kwambiri.
Pakapangidwe kake, ikafika pamfundo, zinthuzo zitha kutenga mawonekedwe apadera ndikusintha zofuna za opanga: ngati amapanga mabotolo azogulitsa pabanja kapena matope amalima madzi omwe amadzaza kutentha kwambiri.
Ichi ndichifukwa chake mapaipi a TIP amalimbana ndi kutukuka ndikukhazikika motsutsana ndi zomwe amakumana ndi mankhwala.
HDPA imagonjetsedwa kwambiri komanso yopanda madzi
Mwayi wina osati wocheperako, hdpe amalephera kwambiri!
• HDPA imagonjanso monga momwe imakhalira: chifukwa chake mapaipi omwe amayendetsa madzi ankhanza sangagonjere "kutumphuka". Sipadzakhala kusintha kwa chitoliro kapena kuchuluka kwa zolimbitsa pakapita nthawi.
• Kutsutsana ndi dothi lankhanza: munjira yomweyo, ngati dothi likakhala ndi ma pamoyo ndi ma pipi, mawonekedwe ake sayenera kusinthidwa
• HDPAnso yolimbanso ndi zovuta zakunja zomwe zingachitike: mphamvu zofalikira nthawi idzagwedezeka ndiye zimapangitsa kuwonongeka kwa gawo m'malo mododometsa kwake. Momwemonso, chiopsezo cha nyundo yamadzi chimachepetsedwa kwambiri ndi HDPE
Mapaipi a HDPA ndi opanda ungwiro: Kumadzi kapena mpweya. Ndi mu 1610 muyezo womwe umalola mwachitsanzo kuti ayesetse kulimba kwa chubu.
Pomaliza, pamene akuda wakuda, hdpe amatha kupirira UV
HDPA ndi yopepuka koma yamphamvu
Kwa masamba opangira mafakitale, kuunika kwa hdpe ndi mwayi wosatsutsika: Mapaipi a HDPA ndi osavuta kunyamula, kusuntha kapena kusungira.
Mwachitsanzo, polypropylene, mita imodzi ya chitoliro chokhala ndi mainchesi osakwana 300 zolemera:
• 5 kg mu hdpe
• 66 kg mu chitsulo
• 150 kg konkriti
M'malo mwake, pakuthana ndi kuchuluka, kukhazikitsa mapaipi a HDPPA kumatha kosavuta ndipo kumafunikira zida zopepuka.
Chitoliro cha HDPpe chimagonjetseka, chifukwa chimakhalapo nthawi kuyambira pomwe moyo wake ukhoza kukhala wautali kwambiri (makamaka HDPE 100).
Chitolirochi cha chitolirochi chimadalira zinthu zosiyanasiyana: kukula, kuthamanga kwamkati kapena kutentha kwa madzimadzi mkati. Tikulankhula zaka 50 mpaka 100 za moyo wautali.
Zoyipa zogwiritsa ntchito kwambiri polyethylene pa malo omanga
M'malo mwake, mavuto ogwiritsa ntchito chitoliro cha HDPPA alinso.
Titha kunena mwachitsanzo:
• Malo okhazikitsa panthawi yomanga ayenera kukhala osamala: Kuthana ndi anthu
• Sipangathe kugwiritsa ntchito galu kapena kuluma kuti mulumikizane mapaipi awiri a HDPE
• Pali chiopsezo cha mapaipi akati polumikizana ndi mapaipi awiri
• HDPA imayamwa kwambiri kuposa zinthu zina (monga kuponyera chitsulo), zomwe ndizovuta kudziwa
• Ndipo oyang'anira amataya. Njira zotsika mtengo kwambiri zimagwiritsidwa ntchito poyang'anira njira (hydrophone njira)
• Kukula kwa mafuta ndikofunikira ndi HDPE: Pupe ikhoza kusokoneza kutentha
• Ndikofunikira kulemekeza kutentha kogwiritsa ntchito malinga ndi mikhalidwe ya HDPE
