Imyambaro n'imiringoti bya Epoxy byashyizwemo imiyoboro y'amazi y'icyuma

Iri ni itegeko ry’ishyirahamwe ry’Abanyamerika rishinzwe amazi (AWWA). Irangi rya FBE rikoreshwa cyane cyane ku miyoboro y’amazi y’icyuma n’ibikoresho byayo, urugero nk’imiyoboro ya SSAW, imiyoboro ya ERW, imiyoboro ya LSAW idakora neza, inkokora, imigozi, ibinini bigabanya ubushyuhe n’ibindi mu rwego rwo kurinda ingese.

Imyambaro ya epoxy ifatanye na fusion ni imwe mu myambaro ya thermosetting y'ifu yumye, iyo ubushyuhe butangiye gukora, ikora reaction ya shimi ku buso bw'umuyoboro w'icyuma mu gihe ikomeza gukora neza. Kuva mu 1960, ikoreshwa ryagiye rigera ku ngano nini y'imiyoboro nk'imyambaro yo imbere n'inyuma yo gukoresha gazi, peteroli, amazi n'amazi yanduye.

Ibirango by'ibicuruzwa

Imiterere ifatika y'ibikoresho by'ifu ya epoxy

Uburemere bwihariye kuri 23℃: nibura 1.2 na ntarengwa 1.8
Isesengura ry'urusenda: ntarengwa 2.0
Igihe cya jeli kuri 200 ℃: munsi ya 120s

Gusukura ibisasu bivanze n'umuriro

Ubuso bw'icyuma cyambaye ubusa bugomba gusukurwa nk'uko bivugwa muri SSPC-SP10/NACE No. 2 keretse iyo umuguzi yabigennye ukundi. Ishusho y'icyuma cyasashe cyangwa ubujyakuzimu bw'urumuri bigomba kuba hagati ya 1.5 mil kugeza 4.0 mil (38 µm kugeza 102 µm) hakurikijwe ASTM D4417.

Gushyushya

Umuyoboro usukuye ugomba gushyushya ubushyuhe buri munsi ya dogere 260, isoko y'ubushyuhe ntigomba kwanduza ubuso bw'umuyoboro.

Ubunini

Ifu yo gusiga igomba gushyirwa ku muyoboro ushyushye ku bugari bungana bwa 305μm (12 mils) inyuma cyangwa imbere. Ubugari ntarengwa ntibugomba kurenza 406μm keretse iyo byasabwe n'uwakoze cyangwa uwabiguze.

Gupima imikorere ya epoxy nta yandi mahitamo

Umuguzi ashobora gushyiraho isuzuma ryinyongera kugira ngo amenye imikorere ya epoxy. Uburyo bukurikira bwo gupima, bwose bugomba gukorwa ku mpeta zo gupima imiyoboro, bushobora kugaragazwa:
1. Ubushobozi bwo gupfundika ibice.
2. Uburyo bwo gupima aho umurongo uherereye.
3. Isesengura ry'ubushyuhe (DSC).
4. Gukomereka burundu (guhindagurika).
5. Kuroba mu mazi.
6. Ingaruka.
7. Ikizamini cyo gusenyuka kwa Cathodic.

Ibanjirije iyi: Umuyoboro w'Ubushinwa w'Umwuga wo Guteramo Imbunda - Imiyoboro ikonje, EN10219 S235JRH, S235J0H, S355JRH, S355J0H - Izunguruka

Ibikurikira: Imiyoboro ya Api 5l y'umurongo iva kuri grade B kugeza kuri X70 Od kuva kuri 219mm kugeza kuri 3500mm

Andika ubutumwa bwawe hano hanyuma ubwoherereze
