ISO 21809-1ikoreshwa ku miyoboro y'amazi itwikiriwe cyangwa iri munsi y'amazi mu nganda za peteroli na gaze kandi ikagaragaza ibisabwa kugira ngo habeho irangi ryo kurinda ingese ryo hanze3LPE na 3LPPkuriimiyoboro y'icyuma ishongeshejwe kandi idasobekeranye.
Hari ubwoko butatu bw'ibikoresho byo hejuru, bitewe n'ubwoko bw'ibikoresho byo hejuru:
A: LDPE (polyethylene ifite ubucucike buke);
B: MDPE/HDPE (polyethylene ifite ubucucike buringaniye)/(polyethylene ifite ubucucike bwinshi);
C: PP (Polypropylene).
Ibisabwa kuri buri gikoresho bisobanurwa birambuye mu gice gikurikira ku bisabwa kuri ibyo bikoresho bitatu fatizo.
| Isomo ryo gusiga | Ibikoresho byo hejuru | Ubushyuhe bw'igishushanyo (°C) |
| A | LDPE | -20 kugeza + 60 |
| B | MDPE/HDPE | -40 kugeza + 80 |
| C | PP | -20 kugeza + 110 |
Sisitemu yo gusiga igomba kuba igizwe n'ibice bitatu:
Icyiciro cya mbere: epoxy (amazi cyangwa ifu);
Icyiciro cya 2: kole;
Icyiciro cya gatatu: Icyiciro cyo hejuru cya PE/PP gishyirwamo hakoreshejwe extrusion.
Iyo bibaye ngombwa, ushobora gushyiramo agapira gakomeye kugira ngo wongere ubushobozi bwo kugwa. Cyane cyane aho bisaba ko habaho gufata neza no kugabanya ibyago byo kunyerera.
Ubunini bw'urutonde rwa Epoxy Resin
Ntarengwa 400 um
Ntarengwa: Liquid epoxу: byibuze 50um; FBE: byibuze125um.
Ubunini bw'urutonde rufatana
Nibura 150m ku gice cy'umuyoboro
Ubunini bwose bwo gutwikira
Ubunini bw'urwego rurwanya ingese buhinduka bitewe n'umutwaro w'aho hantu n'uburemere bw'umuyoboro,kandi urwego rw'ubugari bw'urwego rurwanya ingese rugomba gutoranywa hakurikijwe imiterere y'inyubako, uburyo bwo gushyiraho imiyoboro, imiterere y'ikoreshwa, n'ingano y'imiyoboro.
Pm ni uburemere bw'umuyoboro w'icyuma kuri metero imwe.
bishobora kubazwa ukoresheje uburyo bujyanye nabyoimbonerahamwe y'uburemere bw'umuyoboro w'icyuma gisanzwe, cyangwa ukurikije formula:
Pm=(DT)×T×0.02466
D ni umurambararo w'inyuma wavuzwe, ugaragazwa muri mm;
T ni ubugari bw'urukuta bwagaragajwe, bugaragazwa muri mm;
Ibisabwa ku bikoresho bya Epoxy
Ibisabwa ku bikoresho byo gufatana
Ibisabwa kuri PE/PP Top Layer
Uburyo bwo kurwanya ingese bushobora kugabanywamo ibice bikurikira:
1. Gutegura ubuso;
2. Gukoresha irangi
3. Gukonjesha
4. Kugabanya amafaranga
5. Gushyira ikimenyetso
6. Igenzura ry'ibicuruzwa byarangiye
1. Gutegura ubuso
Ibisabwa nk'ibyo biboneka mu mahame ya SSPC na NACE, kandi ibi bikurikira ni itumanaho rusange:
| ISO 8501-1 | NACE | SSPC-SP | Ishyirwa mu mwanya |
| Ku wa 2.5 | 2 | 10 | Gusukura ibyuma hafi y'umweru |
| Ku wa 3 | 1 | 5 | Gusukura ibyuma byera |
Menya ko ingaruka za Sa 2.5 zidahinduka bitewe n'ingano y'ubushyuhe bw'umuyoboro w'icyuma, ushyirwa mu byiciro A, B, C, na D, bihuye n'ingaruka 4.
2. Gukoresha irangi
Menya neza ko ubushyuhe bwo gushyushya mbere y'igihe n'umuvuduko w'umuyoboro w'icyuma mu gihe cyo gutwikira bikwiye kugira ngo ifu ikomeze neza kandi ifatanye neza n'igitambaro ndetse no kugenzura ubugari bw'igitambaro.
Ubunini bw'urwego rwo kurinda ingese nabwo bufitanye isano n'ibipimo by'ibikoresho byo gusiga.
3. Gukonjesha
Irangi rishyirwamo rigomba gukonjeshwa kugeza ku bushyuhe budatuma imikorere yaryo yangirika mu gihe cyo kurangiza no kugenzura bwa nyuma.
Muri rusange, ubushyuhe bwo gukonjesha bwa 3LPE ntiburenze 60°C, kandi ubushyuhe bwo gukonjesha bwa 3LPP buzaba buri hejuru gato.
4. Kugabanya amafaranga
Uburebure runaka bw'igitambaro bugomba gukurwaho ku mpera zombi z'umuyoboro kandi urwego rwo kurinda ingese ntirugomba gushyirwa ku nguni irenga 30° kugira ngo hirindwe kwangirika kw'igitambaro cyo kurinda ingese mu gihe cyo gusudira.
5. Gushyira ikimenyetso
Gukurikiza amahame n'ibyo abakiriya bakeneye.
Ibi bimenyetso bigomba gusigwa cyangwa gusigwa irangi kugira ngo inyuguti zigaragare neza kandi zidashira.
6. Igenzura ry'ibicuruzwa ryarangiye
Igenzura ryimbitse ry'imiyoboro irwanya ingese irangiye kugira ngo huzuzwe ibisabwa na ISO 21809-1.
Porogaramu za 3LPE
Irangi rya 3LPE ritanga ubushobozi bwo kurwanya imiti myinshi, uburinzi bwiza bwa mekanike ndetse no kuramba neza, ndetse n'amafaranga make yo kubungabunga.
Ikwiriye imiyoboro itwikiriwe cyangwa iri munsi y'amazi ikenera kurwanya ingese nyinshi no kurindwa ikoranabuhanga mu butaka n'amazi.
Ikoreshwa cyane mu miyoboro y'amazi mu gutwara peteroli, gazi n'amazi.
Porogaramu za 3LPP
Irangi rya 3LPP rifite ubushobozi bwo kurwanya ubushyuhe bwinshi kandi rituma riguma neza kurusha polyethylene. Ariko, rishobora kwangirika iyo ubushyuhe buri hasi.
Bikwiriye ubushyuhe bwinshi n'ahantu hagoye cyane, nko gushyira imiyoboro mu duce dushyuha cyane cyangwa hafi y'inganda zitunganya imiti.
Ubusanzwe ikoreshwa mu miyoboro ya peteroli na gaze aho bisaba imikorere ijyanye n'ubushyuhe bwinshi.
DIN 30670: Irangi rya polyethylene ry'imiyoboro y'icyuma n'ibikoresho byayo.
Iyi ni ihame ry’inganda zo mu Budage ryihariye ku birebana n’amatafari ya polyethylene ku miyoboro y’icyuma n’ibikoresho byayo.

Sisitemu yo gusiga polypropylene by'umwihariko ku miyoboro y'icyuma.
GB/T 23257: Ibipimo ngenderwaho by'ikoranabuhanga ryo gusiga polyethylene ku muyoboro w'icyuma gipfundikiye.
Iri ni ihame ry’igihugu mu Bushinwa rijyanye n’ikoranabuhanga ryo gusiga polyethylene ku miyoboro y’ibyuma itwikiriwe.
CSA Z245.21: Irangi ryo hanze rikoreshwa mu bimera ku muyoboro w'icyuma.
Iri ni ihame ry’ishyirahamwe ry’ibipimo bya Kanada (CSA) rigena ibisabwa ku irangi rya polyethylene ryo hanze rikoreshwa mu kurinda imiyoboro y’icyuma.
Gukwirakwiza ibicuruzwa mu buryo bwuzuye: Dutanga amahitamo menshi y'imiyoboro y'icyuma cya karuboni kuva ku byuma bisanzwe kugeza ku byuma bigezweho kugira ngo bihuze n'ibyo ukeneye bitandukanye.
Ingwate y'ubuziranenge: Ibicuruzwa byose byubahiriza amahame mpuzamahanga y’ubuziranenge, nka ISO 21809-1, byagenewe by’umwihariko ibikenewe mu nganda za peteroli na gaze mu kurwanya ingese.
Serivisi yihariye: Ntabwo dutanga gusa ibicuruzwa bisanzwe, ahubwo bitewe n'ibisabwa n'umushinga n'imiterere y'ibidukikije, irangi ririnda ingese n'imiyoboro y'icyuma bishobora guhindurwa kugira ngo harebwe imikorere myiza kandi bigire akamaro ku giciro gito.
Ubufasha mu bya tekiniki na serivisi ku bakiliya: Itsinda ryacu ry'impuguke ritanga inama n'ubufasha mu bya tekiniki kugira ngo rifashe abakiriya guhitamo imiyoboro y'icyuma ikwiye n'ibisubizo birwanya ingese kugira ngo imishinga yabo ishyirwe mu bikorwa neza.
Gusubiza vuba no gutanga serivisi: Dufite ububiko bunini n'uburyo bwiza bwo gutwara ibintu, dushobora gusubiza vuba ibyo abakiriya bakeneye no kwemeza ko bitangwa ku gihe.
Twiteguye gukorana namwe mu gutanga imiyoboro y'icyuma myiza cyane hamwe n'ibisubizo byo kwirinda ingese ku mishinga yanyu. Twandikire kugira ngo ubone ibisobanuro birambuye ku bicuruzwa byanyu, twishimiye kubafasha kubona uburyo bwiza bwo gukoresha imiyoboro y'icyuma bujyanye n'ibyo mukeneye!
