Chifukwa cha kuchepa kwa mphamvu ndi nkhokwe zosungiramo zinthu, zombo zapaipi zimanyamula gasi wochulukirachulukira, phula ndi mafuta ena otsika kwambiri, ndipo ntchito yomanga mapaipi apanyanja ikukula mosalekeza. Chitukuko sichinasokonezedwe. M'munsimu muli mawu oyamba a matekinoloje ena.
Kutentha kwambiri kugonjetsedwa ndi 3pe anticorrosion
Chithandizo chapamtunda Kuwombera kwakunja mulingo wa 2.5, tattoo 60 microns. Pambuyo kuwombera kuphulika ndi kuchotsa dzimbiri, pamwamba pa chitoliro chachitsulo chimatsukidwa ndi phosphoric acid ndi chromate kuchotsa fumbi lomwe lili pamwamba pa chitoliro chachitsulo.
Wosanjikiza woyamba amagwiritsa ntchito FBE anti-corrosion epoxy powder m'malo mwa ufa wamba wa 3pe anti-corrosion, womwe umapangitsa kuti zinthu zizikhala bwino komanso zimathandizira kumamatira ndi FBE. Kutentha kwa magalasi a FBE kuli pakati pa 100-150 ° C, ndi Vicat kufewetsa zomatira Malo ochepetsetsa a HDPE ndi 124 ° C chifukwa cha kugawa kwake kocheperako kwa maselo, katundu wolimba komanso kukana kwambiri kuwonongeka kwa makina.
Gawo lachiwiri ndilofunika kwambiri. Kutentha kwapamwamba kwa 3pe kumadalira momwe zinthu ziliri. Pakadali pano, zida zopangira zida zapamwamba zodziyimira pawokha ndi Xinlong Anticorrosion zimatengera zomwe zidachokera kumakampani ogwiritsira ntchito. Kutentha kwa kutentha kwa zomatira kumachepetsedwa ndi 20 ° C, kutentha kwapamwamba kwambiri kwa 3pe anti-corrosion wosanjikiza kumapezedwa.
