ʻO ke kiʻi pena o ka epoxy powder anticorrosive steel tube he paʻakikī, kūpaʻa wai a ʻaʻole ʻona.Paʻa ikaika, pili maikaʻi ma waena o ke kiʻi pena a me ke kiʻi pena.ʻOi aku ka maikaʻi o ka anti-rust a me ka pale wai, ka hoʻohana ʻana i nā mea anti-rust raw maikaʻi loa, e hōʻoia i kāna hana anti-rust.Loaʻa iā ia ka ikaika mechanical maikaʻi, ke kiʻi paʻakikī, ka pale abrasion a me ka hopena hopena.Maʻiʻo paʻa kiʻekiʻe, kiʻiʻoniʻoni mānoanoa.Hōʻike ʻia ka molecular structure o ka epoxy powder anticorrosive steel pipe e nā pūʻulu epoxy ikaika i ke kaulahao mole, hiki ke loaʻa ma ka hopena, waena a i ʻole ke apo o ke kaulahao mole.
Ma muli o nā pūʻulu epoxy ikaika i loko o ka molecular structure, hiki iā lākou ke crosslink me nā ʻano lāʻau lapaʻau like ʻole e hana i nā polymers insoluble a infusible me ka hoʻolālā pūnaewele ʻekolu ala.Hoʻohana nui ʻia nā ʻāpana pauka Thermosetting i nā ʻāina like ʻole: nā ʻāpana pauka epoxy, nā ʻāpana pauka epoxy phenolic, nā ʻāpana pauka polyester, nā ʻāpana pauka epoxy-polyester.I waena o lākou, ʻo ka epoxy powder coating ke ʻano o ka noi mua ʻana, ʻo ia hoʻi ka hana ʻana o ka pauka pauka i kēia manawa, hoʻohana nui ʻia i ke kaʻina hana electrostatic spraying, i ka hoʻonaninani hoʻonaninani ke kūlana koʻikoʻi;Ma muli o kona kūpaʻa kino kino kiʻekiʻe, hoʻohana nui ʻia ka epoxy phenolic powder coating no ka uhi anti-corrosion.
ʻO ka nui o nā uhi pauka Thermoplastic
ʻO ka uhi ʻana o ka pauka polyethylene, ka uhi ʻana o ka pauka POLYvinyl chloride, ka uhi ʻana o ka pauka polypropylene, ka uhi ʻana o ka pauka polyether chlorinated, ka uhi ʻana o ka nylon, ka uhi ʻana o ka pauka polyphenylene sulfide, a me nā mea ʻē aʻe.ʻOi aku ka maikaʻi o ka hoʻōla ʻana o nā plastic thermosetting ma muli o ko lākou kaumaha molekala liʻiliʻi, kahi e hoʻopili ikaika ai lākou i ke kino o ka paipu i ka wā e uhi ai i ka paipu kila, a hiki ke hana i ka paipu kila i uhi ʻia e loaʻa i kahi kiʻi ʻoniʻoni ʻoniʻoni.ʻO nā plastic thermosetting maʻamau: epoxy resin, phenolic resin, amino resin a pēlā aku.ʻO ka mānoanoa o ka pā uhi ma waena o 100 microns a me 500 microns, maʻamau 350 microns.
Ma waho o ka PE composite i uhi ʻia i ka paipu plastik, 1. ʻO ke olakino, ʻaʻohe mea ʻawaʻawa, ʻaʻohe scaling, ʻaʻohe hānau o nā microorganisms, e hōʻoia i ka maikaʻi o ka wai 2. 3. ʻO ke kaʻina hoʻonohonoho he oʻo, kūpono a wikiwiki hoʻi, a ʻo ka pilina me ka paipu galvanized maʻamau. ka mea like.4. Kūleʻa maikaʻi i ka wā.5. Paʻa paipu maʻemaʻe, hoʻomaikaʻi i ka lawe ʻana i ka pono, lōʻihi ke ola o ka lawelawe.
Ma waho o ka paipu plastik i uhi ʻia i ka PE, ke ʻano pili:pili pili: e hoʻohana i ka uea make manual a i ʻole ka mīkini lima uea uila e hana i ke kaula paipu, e hoʻolohe i ka hoʻoluʻu i ka wā e hana ai;Hoʻopili Flange, ana ma ka paena, kaha kiʻi paipu laina laina hoʻoheheʻe palapala palapala, ka uhi ʻana i ka uhi ʻana, ka lining plastic, a laila lawe ʻia i kahi hoʻonohonoho pūnaewele;Hiki ke ho'ohana 'ia ka paipu kila i ho'opa'a 'ole 'ia, a me ka paipu paipu ma ke kula, ka wiliwili flange, ka hui 'ana i ka pipeline, a laila wehe 'ia no ka uhi 'ana, ka ho'ohehe'e 'ia, a laila lawe 'ia i ka ho'okomo 'ana i ka paena;Pono e makemake ʻia nā mea hoʻopili paipu plastik i uhi ʻia i hoʻopau ʻia;E paʻiʻia nā'ōpuʻu e ka mīkini rolling groove, aʻo nā'auwaʻa e like me nā kūlana kūpono.
