Onyinye - bụ a pụrụ ịdabere na nchedo nke ngwá si aka ike na gburugburu

Ke eletriki injinịa, anyị na-emekarị na-ezute okwu "compound". Gịnị ka ọ bụ? Onyinye - bụ egbochi ihe compound na na oge nke na ojiji bụ a mmiri mmiri, na mgbe ahụ a gwọrọ ọrịa, ọ bụghị ya mejupụtara solvents. The compound anaghị ida ya Njirimara na a okpomọkụ nso si -50 ka +200 degrees Celsius, bụ eguzogide radieshon maka impregnation, agbapụtara ọnụ, redio akụkụ, eletriki nchebe maka ndị e biri ebi sekit mbadamba na ha mmiri megide mpụga mmetụta (n'ibu, kwes, chemical, vibration), karịsịa na ọjọọ gburugburu. Mgbe niile, ọnọdụ n'okpuru nke nwere iji rụọ ọrụ electronic na ọkụ na ngwaọrụ na apparatuses bụ anya site laabu. Nke a ala okpomọkụ nke Far North, na elu iru mmiri nke okpomọkụ, na-enweghị omume enyi na gburugburu ebe obibi nke ohere, na na na. D. All nke n'elu na-ese imewe engineer iji chebe-eji na a par na mmiri ọgwụ ọchụ coatings jikọtara ihe maka potting na encapsulation mmiri na akụrụngwa. Ọtụtụ mgbe na-eji maka nzube a abụọ-akụrụngwa mixtures.

Site Njirimara nke ogige na-ekewa n'ime:

- impregnation;

- eletriki;

- mgbatị;

- agbanwe;

- plasticized roba;

- a ala molekụla ibu plasticizer.

Impregnating compound - a compound na-eji maka impregnation nke windings nke Motors na ígwè ọrụ.

Egbochi ihe, n'aka nke ya, na-ekewa n'ime:

- thermoset (adịghị nro mgbe n'ịgwọ). Ndị a gụnyere epoxy, polyester na ndị ọzọ na resins;

- thermoplastic (nro n'elu kpo oku) - bitumens waxy dielectrics, thermoplastic Polymers (polystyrene, polyisobutylene).

Igbo compound - a mejupụtara n'ihi na ejuputa cavities cable igbe, nakwa dị ka oru na electric igwe na ngwaọrụ.

Egbochi ihe ngwakọta mere si methacrylic esters, na-eji dị ka ma ndị impregnation na nkedo. Ndị dị otú ahụ ogige mgbe agwọ na okpomọkụ nke 70-100 degrees Celsius (pụrụ iche hardener, a fọrọ lowered 20 degrees), na-thermosetting na ike ga-eji na okpomọkụ si -55 ka +105 degrees. Ha na-eji maka impregnation nke iche iche nke n'usoro ngwá (na eriri igwe asọfe Motors na al.) Nke na-enye irè nchedo electrocution.

Potting compound dabeere na bitumen na larịị nke okpomọkụ na-eguzogide (105 ° C) bụ nke klas "A". Ọ nwere kasị elu okpomọkụ na-eguzogide epoxy na silicone ogige.

Na-agbanwe plasticized roba mixtures hụrụ akpan akpan ngwa. Taa bụ nnọọ ewu ewu compound maka iche-iche. N'ihi na e mere ya na-agbanwe silicone Ebu nke dị iche iche configurations. The okpomọkụ ọchịchị nke compound esịmde a ịgba na + 200 ° C, ọ bụ kpụ ọkụ n'ọnụ karịrị 250 ° C na-atụ aro n'ihi na polima-ebibi linkages.

Ugbu a ọ na-arụpụta dị iche iche akara ule nke ogige, ọ bụla nke hụrụ ya akporo na nwere Njirimara na-ahụkarị nke ya.

Kasị ewu ewu ghọrọ epoxy compound - a polima na ala shrinkage, magburu onwe dielectric e ji mara na elu adhesion. Ọ bụ ike na-arụ ọrụ na ọnọdụ nke na-adịgide adịgide deformation. Epoxy resins na-n'ọtụtụ ebe dị iche iche na ngwá, nrụnye, owuwu. Ndị a mixtures na-dakọtara na ndị ọzọ oligomers ma mee ngwangwa ha hardening site agwakọta na ndị ọzọ ogige. The drawback nke epoxy resin bụ a ala ọrụ okpomọkụ, nke na-eme ka ọ ghara ikwe iji ya na a na Usoro na-arụ ọrụ na a kama njọ.

Chịkọta, anyị nwere ike ikwu na ojiji nke ogige enwekwu arụmọrụ pụrụ ịdabere na gbatịrị ọrụ ndụ nke na kọmputa ngwaọrụ na ọkụ na ngwá, ana achi achi ha akara na nchedo vibration, na-enyere chebe-eji ọkụ si eletrik.
