ʻO ka uhi ʻana i ka pauka Thermosetting no ka hoʻoheheʻe ʻana i ka electrostatic
ʻO ka wehewehe pōkole o ka uhi pauda
ʻOkoʻa loa ke ʻano o ka pauka pauka no ka ʻenehana hoʻoheheʻe electrostatic mai nā uhi maʻamau a aia ma ke ʻano o ka pauka maikaʻi. No ka mea ʻaʻohe mea hoʻoheheʻe, ua kapa ʻia lākou he pauka. ʻO nā hiʻohiʻona nui o nā uhi pauka: ʻaʻohe pōʻino, maikaʻi, mālama waiwai a pili i ke kaiapuni.
ʻO ka pauka Thermosetting kahi ʻano maʻamau o ka pauka electrostatic spraying a ʻo kekahi o nā mea mua e hoʻomohala ʻia a hoʻohana ʻia. He kiʻekiʻe ka paʻakikī, ke kūpaʻa kemika maikaʻi a me ke kūpaʻa kiʻekiʻe kiʻekiʻe, a hoʻohana nui ʻia i ka uhi ʻana i ka ʻoihana, ka hana ʻana, ke kūkulu ʻana a me nā māla ʻē aʻe. Hoʻohana maʻamau ia i nā pauka thermosetting me ka epoxy, polyester, acrylate a me ka polyether.
Hōʻike Huahana
Hoʻokaʻawale maʻamau
Hoʻokaʻawale ʻia nā ʻāpana pauka electrostatic spraying i ʻelua mau ʻāpana: thermoplastic powder coatings a me thermosetting powder coatings.
1. ʻO ka uhi ʻana i ka pauka Thermoplastic
ʻO ka uhi ʻana o Thermoplastic me ka thermoplastic, pigment, filler, binder a me stabilizer. ʻO nā mea hoʻoheheʻe Thermoplastic: polyethylene, polypropylene, polyester, PVC, chlorinated polyether, polyamide, cellulose, polyester a pēlā aku.
2. ʻO nā uhi pauka Thermosetting
ʻO ka uhi ʻana i ka pauka Thermosetting he resin thermosetting, curing agent, pigment, filler a me nā mea hoʻohui. ʻO ka uhi ʻana o ka pauka Thermosetting: epoxy resin, epoxy polyester, polyester, polyurethane, acrylic resin a pēlā aku.
Pono
Hiki ke hoʻokaʻawale ʻia ka pauka plastik i ka pauka thermoplastic a me ka pauka thermosetting; ka pauka waho a me ka pauka o loko; ka pauda kū'ē i ka wela a me ka pauda wela haʻahaʻa.
1. ʻO nā mea maikaʻi o ka pauka plastic thermoplastic he paʻakikī, kūlou maikaʻi, kūpaʻa kemika, a hiki ke hoʻopili ʻia i ka uhi ʻana o ke kiʻi ʻoniʻoni mānoanoa.
2. ʻO ka maikaʻi o ka pauka i loko, ʻoi aku ka nāwaliwali o ka hana ma mua o ka pauka o waho, hiki ke hoʻohana ʻia no ka uhi ʻana o ka mea hana i loko, ʻoi aku ke kumukūʻai.
3. Hiki i ka pauka wela kiʻekiʻe ke kū i ke kiʻekiʻe o 200 degere no ka manawa lōʻihi a ʻaʻole hoʻololi ke kala, nā ʻano kino a me nā mechanical o ka laulā i ʻae ʻia.
4. ʻO ka pauka Thermosetting ma ka lumi mahana ʻaʻole ia e palupalu a agglomeration, maikaʻi mechanical dispersion, maʻalahi e hana i kahi kiʻiʻoniʻoni palahalaha.
5. He kūpono ka pauka waho no ka uhi ʻana o ka mea hana o waho, me ka antioxidant, anti-ultraviolet ray, anti-acid a me ka noe alkali a me ka ua, ka hoʻonui ʻana i ka wela a me ka hana contraction.
6. Hiki i ka pauka haʻahaʻa haʻahaʻa ke pae i loko o ke kiʻi uhi ma 80-150 degere Celsius, a hiki ke hoʻohana ʻia ma ka lāʻau a me ka plastic.
