Epoxy Coated PC Steel Strand
Kenyelletso ea Sehlahisoa
Ts'ebetso ea mono-filament sprayed epoxy steel strand e kopana le litlhoko tsa GB/T25823-2010 "Mono-filament Coated Epoxy Coated Prestressed Steel Strand".
Ts'ebetso ea khoele ea tšepe e tlatsitsoeng ea epoxy e fihlela litlhoko tsa GB/T21073-2007 "Epoxy Coated Seven Wire Prestressed Steel Strand" le JT/T 737-2009 "Filled Epoxy Coated Steel Strand".
Ts'ebetso ea mafura a anti-corrosion: Tumellanong le JG 3007, e entsoe ka sesepa sa carp sa boemo bo phahameng ba lipid acid ho tefisa oli ea liminerale e hloekisitsoeng haholo, ho eketsa li-antioxidants, li-anti-rust agents, anti-corrosion le lisebelisoa tse ling, tse ntlafatsang ho khomarela, ho hanyetsa metsi, ho hanyetsa mafome le ho thibela ho bola ha mafura a anti-corrosion.
Hona joale, ho na le litekanyetso tse peli tsa machaba bakeng sa likhoele tsa tšepe tse koahetsoeng ka epoxy, e leng ASTM A 882/A 882M-02a le IS0 14655:1999 (E). Bakeng sa likhoele tsa tšepe tse koahetsoeng ka epoxy, mefuta e 'meli ea lihlahisoa e hlalositsoe: likhoele tse tlatsitsoeng ka epoxy le likhoele tsa tšepe tse koahetsoeng ka epoxy. Phetolelong ea 2002 ea standard ea ASTM, ho bohlokoa ho hlakisa likhoele tsa tšepe tse tlatsitsoeng ka epoxy, 'me likhoele tsa tšepe tse koahetsoeng ka epoxy ha li khothalletsoe; ISO 14655:1999 (E) e ipapisitse le ASTM A 882/A882M-96 mme ka hona e boloka melaoana ea lihlahisoa tsa likhoele tsa epoxy-coated, ke hore bakeng sa lihlahisoa ka bobeli.
Kaha likhoele tsa tšepe tse koahetsoeng ka epoxy ke sehlahisoa se nang le khanyetso e ntle ea kutu, ho na le melao e thata ea botenya ba ho roala le likoti holim'a maemo ka bobeli. ASTM A 882/A 882M-02a e totobatsa botenya ba ho roala ba 0.38 -1.14mm bakeng sa likhoele tse tlatsitsoeng ka epoxy. IS0 14655: 1999 (E) e bolela hore botenya ba ho roala ha tšepe ea epoxy e koahetsoeng ke 0.40-0.90mm; Botenya ba likhoele tse koahetsoeng ka epoxy ke 0.65 -1.15mm.
ASTM A882/A882M-02a le IS0 14655:1999 (E) ka bobeli li hlakisa hore ho ke ke ha e-ba le masoba a bolelele bo felletseng ba khoele ea tšepe e phethiloeng ka epoxy. Ka nako e ts'oanang, lihlahisoa tsa rona li finyella litlhoko tsa litekanyetso tse peli tsa machaba tsa ASTM A882 / A882M-02a le IS0 14655: 1999 (E) .
Likarolo tsa Sehlahisoa
Likhoele tsa tšepe tse koahetsoeng ka epoxy tse hlahisoang ke k'hamphani ea rona li na le thepa e ntle ea anti-corrosion,
1) Lekhalo pakeng tsa lithapo tsa tšepe tsa khoele ea tšepe li tlatsitsoe ka botlalo ke resin ea epoxy.
2) Sekoaelo sa epoxy resin holim'a khoele ea tšepe e nang le botenya bo lekaneng, 'me ha ho na pinhole bolelele bohle.
3) Resin e khethehileng ea epoxy e tlamahane ka thata le matrix ea tšepe ea tšepe ea tšepe, e atolohang ka mokhoa o ts'oanang 'me e se ke ea phunyeha nakong le ka mor'a tsitsipano.
Lisebelisoa tsa Sehlahisoa
Joalo ka mofuta o mocha oa lisebelisoa tse phahameng tse thibelang kutu, likhoele tsa tšepe tse koahetsoeng ka epoxy li sebelisoa haholo mafapheng a mangata a boenjiniere joalo ka likhoele tse lutseng ka thapo, likhoele tse kentsoeng ka thoko, likhoele tse kantle (ho kenyeletsoa le likhoele tse tlamang), likhoele tse ka hare, geotechnical. anchorage, joalo-joalo, United States, Europe, Japane, Australia le linaheng tse ling tsa Europe, Amerika le Asia-Pacific le libaka.
