Chinese chitoliro kutchinjiriza zitsulo chitoliro wopanga
1. 3PE chitetezo cha dzimbiri
Zitatu wosanjikiza Pe odana dzimbiri dongosolo payipi: woyamba wosanjikiza wa ufa epoxy (FBE> 100um), wachiwiri wosanjikiza zomatira (AD) 170 ~ 250um, ndi wachitatu wosanjikiza wa polyethylene (PE) 2.5 ~ 3.7mm. Zida zitatuzi zikuphatikizidwa ndikuphatikizidwa molimba ndi chitoliro chachitsulo kuti apange chophimba chabwino kwambiri chotsutsana ndi dzimbiri.
M'mimba mwake wa chitoliro Φ 60～ Φ chikwi chimodzi mazana anayi mphambu makumi awiri
2. 2PE anticorrosive zitsulo chitoliro
Zigawo ziwiri za PE anticorrosive kapangidwe kwa payipi, woyamba wosanjikiza zomatira (AD) ndi wachiwiri wosanjikiza wa polyethylene (PE), zida ziwirizo zimaphatikizidwa, ndipo makulidwe amtundu uliwonse ndi wofanana ndi wachitatu wa PE.
Standard: SY / t0413-2002 luso muyezo polyethylene anticorrosive ❖ kuyanika payipi m'manda zitsulo
GB / t23257-2009 luso muyezo polyethylene anticorrosive ❖ kuyanika payipi m'manda zitsulo
3. Single PE anticorrosive zitsulo chitoliro
Kuyerekeza pakati pa polyethylene wosanjikiza umodzi ndi polyethylene yamitundu itatu
Kuyerekeza pakati pa polyethylene wosanjikiza umodzi ndi polyethylene yamitundu itatu
Chitoliro chachitsulo chosanjikiza chimodzi cha PE chimatenga njira yopopera (yomwe imadziwikanso kuti njira yotchinga) kuti izungulire chitoliro chachitsulo chotenthedwa ndi pafupipafupi. Pamwamba pa chitoliro chachitsulo ndi chidebe chokhala ndi ufa wa polyethylene, womwe umapopera pamwamba pa khoma lakunja la chitoliro chachitsulo kuti apange zokutira za polyethylene. Executive muyezo CJ / t120-2008 pulasitiki yokutidwa gulu zitsulo chitoliro kwa madzi.
1. Mapangidwe
Zogulitsazo zimakonzedwa kuchokera ku epoxy resin, phula la malasha, antirust pigment, zowonjezera ndi amine yosinthidwa. Mankhwalawa ali ndi ubwino wowumitsa mofulumira, kumamatira kwabwino, kusinthasintha kwabwino, kulongedza magawo awiri ndi kumanga kosavuta. Ili ndi mawonekedwe a asidi, alkali, mchere, madzi ndi kukana mafuta.
2. Makhalidwe ndi ntchito
Utoto umaphatikiza mawonekedwe amphamvu yamakina apamwamba, mphamvu yayikulu yomatira, kukana kwamadzimadzi kwa epoxy resin ndi kukana madzi, kukana kwa tizilombo komanso kukana mizu ya phula. Ndilo chotchingira choletsa dzimbiri chogwira ntchito kwambiri. Mankhwalawa ali ndi kukana kwamankhwala abwino komanso kukana madzi.
Imagwiritsidwa ntchito poletsa kuwonongeka kwa mapaipi amafuta, gasi ndi madzi, madzi apampopi, gasi, mapaipi, zoyenga mafuta, zopangira mankhwala ndi zimbudzi. Itha kugwiritsidwanso ntchito ngati anti-corrosion of the offshore oil popping platforms and underwater parts of ships, komanso anti-corrosion of migodi ndi zida zapansi panthaka.
High kachulukidwe polyethylene jekete odana ndi dzimbiri dongosolo: chitsulo chitoliro wokutidwa ndi mkulu-kachulukidwe polyethylene chuma, amene ali mkulu mawotchi mphamvu ndi kukana dzimbiri bwino, ndipo angateteze chitoliro zitsulo ku kuwonongeka chifukwa cha zinthu kunja pa kayendedwe, unsembe ndi ntchito. Antioxidant, ultraviolet stabilizer, carbon black, ndi zina zotero zidzawonjezedwa popanga manja akunja. Manja akunja a polyethylene ndi osavuta kukalamba. Ngati yasungidwa panja, iyenera kuphimbidwa ndi tarpaulin ndi zinthu zina. Malo osungiramo zinthu ayenera kukhala kutali ndi gwero la kutentha kwakukulu ndi gwero la moto. Pambuyo popanga chitoliro chachitsulo chotsutsana ndi dzimbiri, ndizoletsedwa kuti ziwonekere padzuwa ndikuzimitsidwa, mwinamwake manja akunja a polyethylene ndi osavuta kusweka ndi kukhudza ntchito ya mankhwala ndi moyo wautumiki.
Epoxy ufa wakhala wokutidwa ndi electrostatic kupopera njira. Chifukwa cha vuto lomamatira la epoxy powder impregnation process, kulowetsedwa kwa epoxy ufa sikunatchulidwe. Pakalipano, ndi chitukuko chapadera cha phosphating yankho la epoxy powder impregnation ya Sanye, vuto la adhesion la epoxy powder impregnation ndondomeko yagonjetsedwa kwa nthawi yoyamba, ndipo njira yomwe ikubwera ya epoxy powder impregnation yayamba kuonekera.
Zida zoyambira zamapaipi achitsulo odana ndi dzimbiri zimaphatikizapo mapaipi ozungulira, mipope yowongoka, mapaipi opanda msoko, ndi zina zambiri ku China, amagwiritsidwa ntchito kwambiri m'magawo aukadaulo wamapaipi monga kutumizira madzi mtunda wautali, mafuta, makampani opanga mankhwala, gasi, kutentha. , kuyeretsa zimbudzi, gwero la madzi, mlatho, kapangidwe kazitsulo, kutumizira madzi am'madzi ndikuyika mulu.
