Umuyoboro w'Imboro :
Umuyoboro ufatwa nk'uwambaye ubusa iyo udafite agapfundikizo kawufasheho. Ubusanzwe, iyo umaze kuzunguruka ku ruganda rw'icyuma, ibikoresho byambaye ubusa byoherezwa ahantu hagenewe kurinda cyangwa gusiga igipfundikizo cyifuzwa (biterwa n'imiterere y'ubutaka bw'aho ibikoresho bikoreshwa). Umuyoboro wambaye ubusa ni wo bwoko bw'imiyoboro ikoreshwa cyane mu nganda zikora ibipfundikizo kandi akenshi ushyirwa mu butaka kugira ngo ukoreshwe mu nyubako. Nubwo nta bushakashatsi bufatika bwakozwe bwerekana ko umuyoboro wambaye ubusa uhamye kurusha umuyoboro wambaye ubusa wo gushyiramo ibipfundikizo, umuyoboro wambaye ubusa ni wo usanzwe ku nganda zikora ibipfundikizo.
Umuyoboro wo gusakaza ibyuma :
Gushyira galvanizing cyangwa galvanizing ni bumwe mu bwoko buzwi cyane bwo gusiga imiyoboro y'icyuma. Nubwo icyuma ubwacyo gifite imiterere myiza mu bijyanye no kurwanya ingese no gukomera kw'imitsi, kigomba gusigwa zinc kugira ngo gikore neza. Gushyira galvanizing bishobora gukorwa mu buryo butandukanye, bitewe n'uko uburyo buhari. Ariko, uburyo buzwi cyane ni ugushyira galvanizing mu mazi ashyushye cyangwa mu mazi ashyushye, aho umuyoboro w'icyuma ushyirwa mu mazi ashongeshejwe. Uburyo bwo gukora ibyuma bukorwa n'icyuma gikozwe mu cyuma gikozwe mu cyuma gikozwe mu cyuma na zinc butuma icyuma gishyirwa ku buso bw'icyuma, bigatuma icyuma kidahura n'ingese kitari cyarigeze kibaho mbere. Indi nyungu yo gushyira galvanizing ni inyungu ku giciro. Kubera ko inzira yoroshye kandi idasaba ibikorwa byinshi bya kabiri no gutunganya nyuma yo kuyitunganya, yabaye amahitamo meza ku nganda nyinshi n'inganda.
FBE - Umuyoboro wo gusiga ifu ya Epoxy ivanze na Fusion Bonded :
Iyi miyoboro itanga uburinzi bwiza ku miyoboro mito kugeza kuri minini ifite ubushyuhe buringaniye (-30C kugeza 100C). Ikoreshwa ryayo rikunze gukoreshwa ku miyoboro ya peteroli, gaze, cyangwa amazi. Uburyo bwiza bwo gufatana butuma umuyoboro udashobora kwangirika no kurengera ingese mu gihe kirekire. FBE ishobora gukoreshwa nk'urwego rubiri rutanga imiterere ikomeye igabanya kwangirika mu gihe cyo kuwutwara, kuwutwara, kuwushyiraho no kuwukoresha.
Umuyoboro umwe urwanya kubora: Ingufu zikoreshwa n'amashanyarazi;
Umuyoboro wa Epoxy Irwanya Ubukonje: Ifu ya epoxy yo hasi, hanyuma ifu ya epoxy yo hejuru.
Umuyoboro wo gusigaho Epoxy wa 3PE :
Umuyoboro w'icyuma wa 3PE Epoxy ufite irangi ry'ibice bitatu, icya mbere ni irangi rya FBE, hagati ni irangi rya kole, inyuma ni irangi rya polyethylene. Umuyoboro wa 3PE ni ikindi gicuruzwa gishya cyakozwe ku irangi rya FBE kuva mu myaka ya 1980, kirimo irangi rya PE (polyethylene). 3PE ishobora kongera imiterere y'imiyoboro, irwanya amashanyarazi menshi, idapfa amazi, irashobora kwambarwa, kandi irwanya gusaza.
Kuri urwego rwa mbere ni epoxy ifatanye, ubunini bwayo bukaba burenga 100μm. (FBE ＞ 100μm）
Icyiciro cya kabiri ni ugufatana, ibyo bikaba ari uguhuza epoxy na PE layers. (AD: 170~250μm)
Ibyiciro bya gatatu ni PE layers aribyo polyethylene bifite akamaro ko kurwanya amazi, kurwanya amashanyarazi no kurwanya kwangirika kwa mekanike. (φ300-φ1020mm)
Bityo, umuyoboro wa 3PE wahujwe n'ibyiza bya FBE na PE. Ibyo bikaba birushaho gukoreshwa cyane mu gutwara amazi, gazi na peteroli mu miyoboro itwikiriwe.
