Dielectric - He aha ka mea? dielectric waiwai

Dielectric - he mea ole ka waiwai i kekahi, aole e hele uilaʻikena. Oia conductivity ua loaa no i ka mea uuku, o electrons a me ka Ion. Mau (particles) e hana i loko o ka ole-ana i lawelawe 'mea wale nō ka wā i ke kiʻekiʻe-mahana waiwai. Ka mea i like me ka insulator a e e kūkākūkā i loko o kēia 'atikala.

hōʻikeʻano

Kēlā me kēia lolouila a Radiotechnical alakaʻi mele, mea uholo uila a insulator hoopiiia hele ma ka uilaʻikena, akā, dielectric hiʻona i ka mea, a hiki ma kiʻekiʻe anakahi uila ma luna o 550 V e liu he uuku nui o kaʻikena. Uila pono i loko o ka insulator - ka mea, o ka noi o ka papa (particles) i loko o ka kekahi ao ao (e e maikaʻi 'ole io).

'ano o nā paialewa

Ma ka naau o ka dielectric conductivity mea:

• Omoʻikena -ʻikena i kahe ana i loko o ka dielectric ma kekahi mau pono a laila, a ka mea hiki i ka equilibrium moku'āina, hoʻololi kuhikuhi ana a me ka wā i ke kokuaia mai e anakahi uila i ka mea a me ka wā disconnecting. I ka alternatingʻikena pinepine 'i loko o ka dielectric e e noho i loko o laila i nā manawa, ia mea nō i loko o ka pila nui kahua.
• Electronic conductivity - e neʻe electrons ma lalo o ka aoao o ke kula.
• Ionic conductivity - ho i ka neʻeʻana o ka Ion. Ia ke aupuni 'o electrolyte pāʻoihana - paʻakai, nāʻakika, lye, e like me ka na dielectrics.
• Molionnaya conductivity - i ka neʻeʻana o ka papa (particles) kapa molionami. Ke aupuni 'o colloidal nenoai, emulsions a me ka Wehe' ia mai. Molionov kŰia o ka noi i loko o ka uila ke kahua ua kapaia electrophoresis.

Hō'īpale kumuhana i hoʻolaha ma ka moku'āina o aggregation a me Nine Inch ano. Ka mua puunaueia i paa, wai, gaseous oukou ae hoopaakiki hou. E like me ka mea Nine Inch ano e mahele ia i aloha, inorganics a me organometallic mea.

Conductivity dielectrics hākālia nō o ka aggregation:

• Conductivity kinoea. Ma ka gaseous waiwai i lawa uukuʻikena conduction. Ua hiki ana ma ke alo o ka noa i hoopiiia (particles), a ia lŘlŘ aie a hiki i ka aoao o ka mawaho, a na ionic a me ka lolouila aʻe: X-Ray pāhawewe a me radioactive? Ueony, hookui hookahe koko ana o nā lātoma, a kauoha mai (particles), thermal aʻe.
• Uila conductivity o ka dielectric loli. Mau panalaau: 'ole o ka lātoma, mahana, huikala, i ke alo o ka nui' āhewa 'ana o nā electrons a me ka Ion. Conductivity o ka wai a dielectrics hilinaʻi nui ma luna o ke alo o ka ona a me ka impurities. Conduction o ka uila ua hana hou Polar waiwai me ka wai a hiki i ka dissociated Ion. Ma ke kapakai a ka Polar a me ka ole-Polar fluids, he okoa lanakila ma mua conductivity i. Inā i ka wai a mea hala ole oe i impurities, ka mea e hoʻonui ai i ka ka ho'ēmiʻana o kona mākau waiwai. Me ka ulu ana o ka conductivity o ke kinowai waiwai, a me ka mahana kona emi kona (viscosity) i, i hiki aku ai i māhuahua ion ka hoʻoneʻe.
• Paa dielectrics. Lākou electroconductivity ua kena ae la, e like me ka neʻeʻana o ka papa dielectric (particles) a me impurities. I ka ikaika uila mahinaʻai ia akullaʻikena conductivity.

Ke physical waiwai o dielectrics

A hiki i ka resistivity o ka mea like no ka emi o 10-5 Ohm * m + hiki e wahi ana i na conductors. Inā oi aku 108 Ohm * ka m - i ka dielectrics. Aia nā hihia ma ka resistivity mea mau manawa oi aku ma mua o ka ia'ku o ke alakaʻi mele. Ma ka laulā o 10-5-108 ohm * m + mea he mea uholo uila. Mea hao mea - he alakaʻi mele maikaʻi o ka uilaʻikena.

O ka holoʻokoʻa papa'āweʻaweʻa kemika papa o ka oihana mua, 25 wale nō ole-ke hooheheeia, a me 12 o ka ia e paha e me ka mea uholo uila waiwai. Akā, o ka papa, koe wale no o ka papa o ka 'ona, he mea nō nui oka a, mele a Nine Inch i huiʻia me ka alakaʻi mele waiwai, mea uholo uila a me dielectric. Alaila, ia mea paakiki e lawe mai i kekahi mau kekahi mau waiwai e paa ana o ko lākou mau ia'ku. No ka laʻana, ma ka ho'ēmi i kā wela ololi mea uholo uila, e hele e like dielectric.

palapala noi

Ka hoʻohana a non-i lawelawe 'ia lako ka loa nui, ka mea, o kekahi o ka popularly hoʻohana papa o ka pou eiiiiiaiou. Ua Ua lilo'ākeʻakeʻa i ka mea hiki ke hoʻohana 'ia e ka waiwai o ka hana a me ka OE ano.

Ma ka OE palapala dielectric waiwai i hoʻohana no ka palapala noi i ka uila hō'īpale mea.

Ma kaʻeleu palapala, e ia ka mea, i loko o ka ferroelectric, a me ka 'ike loea hou noi no ka kukuna emitters.

He aha mea he dielectric wai?

Ke polarization o kēia 'ano ia lŘlŘ i loko o ke kula o ka pilaʻikena. Ke kinowai ai ole-lawelawe mea hoʻohana ma o ka akamai no ka hoolei ana a me impregnating kumuhana. Aia i 3 papa o ka wai a dielectrics:

ʻaila kā mea kāhinu, - i haʻahaʻa-(viscosity), aʻano nui 'ole-Polar. Ua pinepine ia i loko o kiʻekiʻe-anakahi uila lako a pan: mea hoʻololi uila aila, kiʻekiʻe wai. Mea hoʻololi uila aila - he pili-Polar dielectric. Uwea aila i ua hoʻohana ma o ka impregnation o hō'īpale pepa-anakahi uila kaula ia ia i ai i 40 kV, a me ka mea hiki ke hooheheeia-ma muli ka penaʻana i ka papa o ka oi aku 120 kV. Mea hoʻololi uila aila i like i ka mea pihana i ka upena 'ole. Kēiaʻano o ka insulator ua hoʻomano hoʻohana 'ia i loko o? Iecaianoaaiiuo, hoʻowahāwahā ke kiʻekiʻe kāki hoʻohālikelike me Analog waiwai a me nāʻano makelia hou.

He aha mea he kemikala insulator? I keia manawa, aneane na wahi a hoole aku la oia, no ka mai o ke kaʻawahia kiʻekiʻe i ua i ma luna o ka muli o chlorinated kalapona. A dielectric wai, ma muli o ka ke aloha silikone, Ua palekana a me ka environmentally aloha. Kēiaʻano Aʻole ole i mea hiki ke hooheheeia ka popopo, a i ka waiwai o ka haʻahaʻa hygroscopicity. Aia thinned insulator ec organofluorine hui i mea pakahi aku la ia mahalo no o ko lākou incombustibility, thermal waiwai a me ka oxidative kumupaʻa.

One hope nānā, ia nō hoʻi mea kāhinu,. Ka mea, e weakly Polar dielectrics, kēia nā linseed, o Diosekouro ka, tung, sesame. O Diosekouro kaʻaila ka loa wela, a ua hoʻohana 'ia ma ka pepa capacitors. Ka aila koena - yiaeaiiacaaeneiie. Omoāea loko o laila ua kena ae la ole maoli omoāea, he Nine Inch naoh i kapaia polymerization. 'Imi hoʻohana ma enamels a me ka pena.
