Hoʻohana ʻia ka varnish impregnation e hoʻopili i nā wili uila a me nā wili e hoʻopiha ai i nā āpau i loko, i hoʻopaʻa ʻia nā uea o nā coils a me nā uea a me nā mea insulating ʻē aʻe e hoʻomaikaʻi i ka ikaika uila, nā waiwai mechanical, conductivity thermal a me nā waiwai pale o ka uila. hoʻokuʻu wili. Hiki iā Ms. Can ke kūkākūkā pōkole me ʻoe e pili ana i ka impregnation varnish i kēia lā, me ka manaʻo e kōkua i ka hoʻoponopono ʻana i ka maikaʻi.
1 Nā koi kumu no ka uila coil impregnation varnish
● Haʻahaʻa viscosity a kiʻekiʻe paʻa maʻiʻo e hōʻoiaʻiʻo maikaʻi permeability a pena e kau ana ka nui;
● Paʻa maikaʻi i ka wā mālama a hoʻohana;
● Ho'ōla maikaʻi a hoʻomaloʻo i nā ʻano, hoʻōla wikiwiki, haʻahaʻa haʻahaʻa, maloʻo maikaʻi i loko;
● Ka ikaika hoʻopaʻa kiʻekiʻe, i hiki i nā mea uila ke kū i ka wikiwiki kiʻekiʻe a me ka hopena mechanical;
● Hoʻohālikelike me nā mea ʻāpana ʻē aʻe;
● Hana maikaʻi kaiapuni.
2 Hoʻohālikelike a me nā ʻano o ka impregnation varnish
● Solvent impregnation varnish. Loaʻa ka solvent impregnation varnish, a ʻo kona ʻike paʻa (mass fraction) ma waena o 40% a me 70%. Ua kapa ʻia ʻo Solvent impregnation varnish me kahi ʻike paʻa i ʻoi aku ma mua o 70% haʻahaʻa-solvent impregnation varnish.
ʻO Solvent impregnation varnish ka mālama paʻa maikaʻi, ka permeability maikaʻi a me nā waiwai hana kiʻiʻoniʻoni, a ʻoi aku ka liʻiliʻi, akā lōʻihi ka lōʻihi o ke kuʻi ʻana a me ka kuke ʻana, a ʻo ke koena o ka solvent ke kumu i nā āpau i loko o ka mea impregnated. ʻO ka mea hoʻoheheʻe maʻalahi hoʻi ka mea e hoʻohaumia ai i ke kaiapuni a me ka ʻōpala, a ua kaupalena ʻia kona hoʻohana ʻana. Hoʻohana nui ia no ka impregnation onā motika uila haʻahaʻaa me nā wili uila.
Hoʻokomo pinepine ʻia ka varnish impregnation solvent-free e ka hoʻoinu ʻana, a hiki ke hoʻohana pū ʻia ka impregnation a me ka hoʻoheheʻe ʻana i ka lepo.
Solvent-free impregnation varnish ho'ōla wikiwiki, he pōkole dipping a me ka baking manawa, aole ea āpau i loko o ka impregnated insulation, he maikai pono, a he kiʻekiʻe uila a me ka mechanical waiwai. Solvent-free impregnation varnish ua hoʻolaha nui ʻia a noi ʻia e hoʻololi i ka solvent-free impregnation varnish i nā mea hana kiʻekiʻe-voltage, nā motika, nā laina hana nui, wikiwiki wikiwiki, a me kekahi mau mīkini kūikawā a me nā mea uila. Eia naʻe, pōkole ka manawa mālama o ka solvent-free impregnation varnish. Hiki ke hoʻopili ʻia ka varnish impregnation me ka ʻole o ka solvent me ka hoʻoinu ʻana, ka hoʻomau mau ʻana, ka ʻōwili ʻia ʻana, ka hoʻoheheʻe ʻana a me ka hoʻopaʻa ʻia ʻana o ka wai.
3 ʻO ka mālama ʻana no ka hoʻohana ʻana i ka varnish impregnation
●Quality hooponopono o ka impregnation varnish i ka wā hoʻohana. ʻO ka pena solvent-free he mea hoʻohui resin polymerizable. ʻO nā ʻano like ʻole o ka solvent-free impregnating paints e polymerize iā ia iho i nā degere like ʻole i ka wā mālama a hoʻohana. ʻO ka hoʻokele pono ʻole e hoʻolalelale i kēia polymerization ponoʻī. I ka manawa e hana ai ka pena me ka solvent-free i loko o nā mea hana impregnation i ka gel, e paʻa koke ia a ʻoki ʻia i loko o 1 a 2 mau lā, e hoʻoulu ai i nā pōʻino nui a me nā poho. No laila, pono e mālama pono ʻia ka maikaʻi o ka pena impregnating solvent-free i hoʻohana ʻia, a pono e lawe ʻia nā ana e hōʻoia i ka paʻa o ka maikaʻi o ka pena.
(1) E nānā mau a nānā i ka maikaʻi o ka pena impregnating i hoʻohana ʻia. Hiki ke hoʻolālā ʻia nā mea nānā a me nā pōʻai nānā e like me ka pena impregnating i hoʻohana ʻia, nā mea hana impregnating a me nā hana hana. Loaʻa nā mea nānā i ka density, density, gel time, moisture content and active diluent content. Inā ʻoi aku ka helu o ka maikaʻi o ka pena i ka palena kiʻekiʻe o ka papa kuhikuhi mana o loko, pono e lawe koke ʻia ka pena hou a i ʻole nā hana ʻē aʻe e hoʻoponopono ai.
(2) Kāohi i ka makū a me nā haumia ʻē aʻe mai ke komo ʻana i ka pena impregnating. ʻO ka epoxy a i ʻole ka polyester solvent-free impregnating pena ʻeleʻele loa i ka makū. ʻO kahi liʻiliʻi o ka wai e komo i ka ʻōnaehana e piʻi koke ka viscosity o ka pena. Pono e pale ʻia ka wai a me nā haumia mai ke komo ʻana i ka pena i ka wā o ka lawe ʻana, mālama a me ka hoʻohana ʻana i ka pena impregnating. Hiki ke hoʻoneʻe ʻia ka wai, ka ea a me nā molekala haʻahaʻa i hui ʻia i loko o ka pena e ka hoʻoheheʻe ʻana a me ka papa pena degassing, a hiki ke kānana ʻia ka wai pena e nā mea kānana. Hoʻopili mau ʻia ka sediment i loko o ka pena e mālama i ka resin maʻemaʻe.
(3) E koho pololei i ka wela o ka impregnation i hiki ai ka viscosity o ka pena i ka waiwai i kuhikuhi ʻia. Hiki ke koho ʻia kēia ma muli o ke kāʻei wela viscosity o ka pena, ʻoiai e noʻonoʻo ana i ka ʻokoʻa ma waena o nā mea hana anu a me nā mea hana wela. Inā kiʻekiʻe loa ka wela o ka luʻu ʻana, e loaʻa iā ia kahi hopena ʻino i ka paʻa viscosity o ka pena; inā haʻahaʻa loa ka wela o ka luʻu ʻana, ʻoi aku ka kiʻekiʻe o ka viscosity a maikaʻi ʻole ka hopena dipping.
(4) E kaapuni mau a hoʻoulu i ka wai pena e mālama i ka mahana o ka wai pena i loko o ka pahu pena a me ka pipeline i haʻahaʻa i hiki ke pale i ka wai pena i loko o ka paipu mai ka hoʻoheheʻe ʻana a me ka paʻa ʻana, kahi e ālai ai i ka paipu pena.
(5) Hoʻohui mau i ka pena hou. ʻO ka pōʻai hoʻohui a me ka nui e pili ana i ka hana hana a me ke ʻano o ka pena. Ma ka hoʻohui ʻana i ka pena hou ma lalo o nā hana hana maʻamau, hiki ke hoʻohana mau ʻia ka pena impregnation i loko o ka pahu pahu no ka manawa lōʻihi.
(6) ʻO ka mālama haʻahaʻa haʻahaʻa e hōʻemi i ka wikiwiki polymerization ponoʻī o ka pena. Hiki ke mālama ʻia ka mahana mālama ma lalo o 10 ° C. No nā manawa lōʻihi i hoʻohana ʻole ʻia a i ʻole nā kūlana kūlana, pono e haʻahaʻa ka mahana o ka mālama ʻana, e like me -5°C.
No ka pena impregnation solvent, ʻo ka manaʻo nui e nānā mau i ka mānoanoa a me ka viscosity o ka pena e mālama ai i loko o ka pae mana.
● ʻO ka hopena o nā haumia i ka hoʻōla ʻana o ka pena impregnation polyester unsaturated. Ua hōʻike ka hoʻomaʻamaʻa ʻana i nā mea e like me ke keleawe a me nā phenols he hopena lohi i ka hoʻōla ʻana o ka pena impregnation polyester unsaturated. ʻO kekahi mau mea ʻē aʻe, e like me ke kaula a me ka ʻaila enameled uea, e hoʻoheheʻe ʻia a pehu ʻia e ka styrene active monomer i loko o ka pena impregnation, e hoʻopili ai ka ʻili o ka mea hana impregnated.
● Pilikia pili. Pono e hoʻokō ʻia nā hoʻokolohua hoʻohālikelike e hōʻoia i ka paʻa piha ʻana o ka pena impregnation me nā mea constituent ʻē aʻe i ka ʻōnaehana insulation.
● pilikia kaʻina hana bakena. Loaʻa i nā varnish impregnation i hoʻokumu ʻia i ka solvent ka nui o nā solvents. ʻO ka maʻamau, hoʻohana ʻia ʻelua a ʻoi aʻe paha ka impregnation, ka kuke ʻana a me ka hoʻonui ʻana i ka mahana e hoʻonui ai i nā kaʻina hana baking no ka pale ʻana i nā pinholes a i ʻole nā āpau i ka kiʻi pena a hoʻomaikaʻi i ka hana a me ke ola o ka insulation coil. Pono e makaʻala ke kaʻina hana ʻana o ka solvent-free impregnation varnishes i mea e pale ai i ka kahe nui ʻana o ke kāpili. Hiki i ka Rotary baking ke hoemi pono i ke kahe o ke kala.
● Pilikia hoʻohaumia kaiapuni. Pono e lawe ʻia nā ʻano kūpono e hoʻomalu i ka mahu solvent a me ka styrene i hoʻokuʻu ʻia i ka wā o ka impregnation a me ke kaʻina hana baking i loko o ka laulā maʻiʻo i ʻae ʻia.
