Ibisobanuro bya HDPE
HDPE ni amagambo ahinnye akoreshwa cyane yerekeza kuri polyethylene yuzuye. Turavuga kandi ibyapa bya PE, LDPE cyangwa PE-HD. Polyethylene ni ibikoresho bya termoplastique bigize umuryango wa plastiki.
Hariho ubwoko butandukanye bwa polyethylene. Itandukaniro risobanurwa nuburyo bwo gukora buzatandukana. Turimo kuvuga kuri polyethylene:
• Ubucucike buke (LDPE)
Ubucucike buri hejuru (HDPE)
Ubucucike buciriritse (PEMD).
Mubyongeyeho, haracyari ubundi bwoko bwa polyethylene: chlorine (PE-C), hamwe nuburemere buke cyane.
Izi mpfunyapfunyo zose nubwoko bwibikoresho birasanzwe munsi ya NF EN ISO 1043-1
HDPE ni ibisubizo byukuri byuburyo bwinshi: Polyethylene yuzuye. Hamwe na hamwe, dushobora gukora ibikinisho byabana, imifuka ya pulasitike, hamwe nu miyoboro ikoreshwa mu gutwara amazi!
HDPE plastike ikorwa muri synthesis ya peteroli. Kubikorwa byayo, HDPE ikubiyemo intambwe zitandukanye:
• kubeshya
Kumeneka
• polymerisation
• granulation
Nyuma yo guhinduka, ibicuruzwa ni amata yera, byoroshye. Biroroshye cyane gushiraho cyangwa ibara.
HDPE koresha imanza mu nganda
Bitewe nimico nibyiza, HDPE ikoreshwa mubice byinshi byinganda.
Iboneka ahantu hose bidukikije mubuzima bwacu bwa buri munsi. Dore ingero zimwe:
Gukora amacupa ya plastike no gupakira plastike
HDPE izwi cyane mu nganda zibiribwa, cyane cyane mu gukora amacupa ya plastiki.
Nibikoresho byiza cyane byokurya cyangwa ibinyobwa cyangwa kurema amacupa. Nta ngaruka zo kumeneka kuko hashobora kubaho ikirahure.
Byongeye kandi, gupakira plastike ya HDPE bifite inyungu nini zo gukoreshwa neza.
Kurenga inganda zibiribwa, HDPE iboneka mubindi bice byinganda muri rusange:
• gukora ibikinisho,
• kurinda plastike kubitabo,
• agasanduku k'ububiko
• mugukora ubwato-kayaks
• kurema urumuri rwa buacon
• n'abandi benshi!
HDPE mu nganda zikora imiti n’imiti
Inganda zimiti n’imiti zikoresha HDPE kuko zifite imiti irwanya imiti. Bivugwa ko ari inimiti.
Rero, bizakora nka kontineri:
• kuri shampo
• ibicuruzwa byo murugo bigomba gukoreshwa ubwitonzi
Gukaraba
• amavuta ya moteri
Irakoreshwa kandi mukurema amacupa yimiti.
Mubyongeyeho, turabona ko amacupa yakozwe muri polypropilene afite imbaraga nyinshi mukubungabunga ibicuruzwa iyo bifite amabara cyangwa pigment.
HDPE kubikorwa byubwubatsi no gutwara amazi
Hanyuma, kamwe mu tundi turere dukoresha cyane HDPE ni umurima wo kuvoma hamwe n’ubwubatsi muri rusange.
Abashinzwe isuku cyangwa ubwubatsi barayikoresha mu kubaka no gushyiraho imiyoboro izakoreshwa mu gutwara amazi (amazi, gaze).
Kuva mu myaka ya za 1950, umuyoboro wa HDPE wasimbuye imiyoboro ya sisitemu. Buhoro buhoro imiyoboro yabujijwe kubera uburozi bwamazi yo kunywa.
Ku rundi ruhande, umuyoboro mwinshi wa polyethylene (HDPE), ni umuyoboro utuma bishoboka ko ikwirakwizwa ry’amazi yo kunywa: ni imwe mu miyoboro ikoreshwa cyane muri iki gikorwa cyo gutanga amazi yo kunywa.
HDPE itanga ibyiza byo kurwanya ubushyuhe bwubushyuhe bwamazi mu muyoboro, bitandukanye na LDPE (ibisobanuro bike polyethylene). Gukwirakwiza amazi ashyushye hejuru ya 60 °, tuzahitamo guhindukirira imiyoboro ya PERT (polyethylene irwanya ubushyuhe).
HDPE ituma kandi bishoboka gutwara gaze ukoresheje tube, gukora imiyoboro cyangwa ibintu bihumeka mu nyubako.
Ibyiza nibibi byo gukoresha HDPE kurubuga rwinganda
Kuki HDPE ikoreshwa byoroshye kurubuga rwinganda? Kandi muburyo bunyuranye, niyihe ngingo mbi zayo?
Ibyiza bya HDPE nkibikoresho
HDPE ni ibikoresho bifite ibintu byinshi byiza byerekana imikoreshereze yabyo mu nganda cyangwa imyitwarire y'amazi mu miyoboro.
HDPE ni ibikoresho bihenze kubwiza bw'intangarugero. Birakomeye cyane (bitavunika) mugihe hasigaye urumuri.
Irashobora kwihanganira ubushyuhe butandukanye bitewe nuburyo bukora (ubushyuhe buke nubushyuhe bwo hejuru: kuva kuri 30 ° C kugeza kuri +100 ° C) hanyuma amaherezo ikarwanya aside aside nyinshi ishobora kuba irimo itarangiritse. sag cyangwa guhindura.
Reka dusobanure bimwe mubyiza byayo:
HDPE: ibikoresho byoroshye
Nkesha inzira yo gukora ikora HDPE, HDPE irwanya ubushyuhe bwinshi cyane.
Mugihe cyibikorwa byo gukora, iyo bigeze aho bishonga, ibikoresho birashobora noneho gufata imiterere yihariye kandi bigahuza nibyifuzo byabayikora: haba gukora amacupa yibicuruzwa byo murugo cyangwa gutanga imiyoboro y'amazi izahanganira ubushyuhe bwinshi cyane.
Niyo mpamvu imiyoboro ya PE irwanya ruswa kandi ihamye kurwanya imiti myinshi.
HDPE irwanya cyane kandi idafite amazi
Iyindi nyungu kandi itari mike, HDPE irwanya cyane!
• HDPE irwanya ruswa: bityo imiyoboro itwara amazi yibasiwe ntishobora gukorerwa "ruswa". Ntabwo hazabaho impinduka mubyimbye cyangwa ubwiza bwa fitingi mugihe.
• Kurwanya ubutaka bukaze: muburyo bumwe, niba ubutaka ari aside kandi umuyoboro ushyinguwe, imiterere yacyo ntabwo ishobora guhinduka.
• HDPE nayo irwanya cyane ihungabana ryo hanze rishobora kubaho: ingufu zitangwa mugihe cyo guhungabana zizatera ihinduka ryigice aho kwangirika. Mu buryo nk'ubwo, ibyago byo kuba inyundo y'amazi bigabanuka cyane hamwe na HDPE
Imiyoboro ya HDPE ntishobora kwemerwa: haba kuvomera cyangwa guhumeka neza. Nibisanzwe NF EN 1610 yemerera kurugero rwo kugerageza ubukana bwigituba.
Hanyuma, iyo ibara ryirabura, HDPE irashobora kwihanganira UV
HDPE iroroshye ariko irakomeye
Ku mbuga zikoreshwa mu nganda, urumuri rwa HDPE ninyungu zidashidikanywaho: Imiyoboro ya HDPE iroroshye gutwara, kwimuka cyangwa kubika.
Kurugero, Polypropilene, metero imwe yumuyoboro ufite diameter iri munsi ya 300 ipima:
• kg 5 muri HDPE
• kg 66 mu byuma
• kg 150 beto
Mubyukuri, mugukemura muri rusange, kwishyiriraho imiyoboro ya HDPE byoroshe kandi bisaba ibikoresho byoroshye.
Umuyoboro wa HDPE nawo urwanya, kuko umara igihe kuko igihe cyacyo gishobora kuba kirekire (cyane cyane HDPE 100).
Igihe cyo kubaho cyumuyoboro kizaterwa nibintu bitandukanye: ubunini, umuvuduko wimbere cyangwa ubushyuhe bwamazi imbere. Turimo kuvuga imyaka 50 kugeza 100 yo kuramba.
Ingaruka zo gukoresha polyethylene yuzuye cyane ahubakwa
Ibinyuranye, ibibi byo gukoresha umuyoboro wa HDPE nabyo birahari.
Turashobora gutanga urugero:
• uburyo bwo kwishyiriraho mugihe cyubwubatsi bugomba kuba bwitondewe: gufata nabi bishobora kwica
• ntibishoboka gukoresha kole cyangwa screw kugirango uhuze imiyoboro ibiri ya HDPE
• harikibazo cyo gukuramo imiyoboro iyo uhujije imiyoboro ibiri
• HDPE ikurura amajwi kuruta ibindi bikoresho (nk'icyuma), bigoye kuyimenya
• bityo ukurikirane ibimeneka. Inzira zihenze cyane noneho zikoreshwa mugukurikirana urusobe (uburyo bwa hydrophone)
Kwagura ubushyuhe ni ngombwa hamwe na HDPE: umuyoboro urashobora guhinduka bitewe n'ubushyuhe
• ni ngombwa kubahiriza ubushyuhe ntarengwa bwo gukora ukurikije imiterere ya HDPE
