Compound - kuyisivikelo onokwethenjelwa imishini kusuka ezindaweni nokhahlo

Ngo ubunjiniyela kagesi, sivamile nazo elithi "kwakwakhe". Kuyini lokhu? Compound - kuyinto kwakwakhe nangokuvikela ukuthi ngesikhathi ukusetshenziswa uketshezi, bese belashwa alikho ngezithako zawo yokususa ingcekeza elenkani. Egcekeni akaphelelwa impahla yayo at lokushisa kusuka -50 kuya +200 degrees Celsius, linamandla emisebeni for impregnation, isizinda ethela, izingxenye umsakazo, Ukuvikelwa kagesi ngoba wesifunda amabhodi ephrintiwe futhi izingxenye zazo ukuze simelane namathonya zangaphandle (mechanical, ezishisayo, zamakhemikhali, vibration), ikakhulukazi ezindaweni nobutha. Phela, izimo babe ngaphansi okufanele isebenze zobuchwepheshe kagesi kanye kanye apparatuses zikude elabhorethri. Lokhu lokushisa ongaphakeme eNyakatho Ekude, kanye nomswakama high we kushisa bhé, futhi esimweni esishubile isikhala, nokunye. D. Konke okungenhla uphika design onjiniyela ukuvikela ukusetshenziswa belingana umswakama oxosha ezinengilazi wawuhlanganisa zokwakha potting kanye encapsulation izingxenye kanye nemishini. Ngokuvamile asetshenziselwe le nhloso ezimbili ingxenye Izingxube.

Ngu property compounds zihlukaniswe zibe:

- impregnation;

- kagesi;

- Ukusakaza;

- Nokunwebeka;

- iraba plasticized;

- ephansi yamangqamuzana isisindo plasticizer.

Bakhulelisa kwakwakhe - ekhuthaza ukuthi isetshenziselwa impregnation ka Windings izinjini futhi imishini.

Ekuvikeleni, esikhundleni salokho, zihlukaniswe zibe:

- thermoset (akasilulazi ngemva kokuphulukisa). Lezi zihlanganisa epoxy, i-polyester nezinye inhlaka;

- Thermoplastic (isihe lapho Ukushisa) - bitumens dielectrics waxy, polymers Thermoplastic (polystyrene, polyisobutylene).

Ukugcwalisa kwakwakhe - laqanjwa ngenxa zokuvala amazinyo anezimbobo ikhebula amabhokisi, kanye uphawu imishini kagesi kanye namadivayisi.

Nangokuvikela ingxube owenziwe kusukela esters methacrylic, asetshenziswa njengoba kokubili impregnation kanye ekusakazeni. compounds ezinjalo ngemva kokuphulukisa ezingeni lokushisa 70-100 degrees Celsius (nge hardener ekhethekile, lokhu embundwini is sehliselwe degrees 20), kuthiwa thermosetting futhi ingasetshenziswa okushisa kusuka degrees -55 kuya +105. Zisetshenziswa ngokuba impregnation izinhlobo ezahlukene imishini ujikelezisa (womhlabathi kanye lekhoyili emazombezombe izinjini futhi al.) Yikuphi ikunika ngesivikelo esiphumelelayo ekuvimbeleni electrocution.

Potting kwakwakhe okusekelwe ibitume ezingeni ukushisa ukumelana (105 ° C) kungokwalabo isigaba "A". It inenani ukushisa ukumelana epoxy futhi abicah compounds.

Izingxube iraba Nokunwebeka plasticized bathole isicelo esithile. Namhlanje kwakwakhe ethandwa kakhulu izinhlobo. Ngoba kwenziwa nezimo abicah isikhunta ukucupha ezahlukene. Umbuso lokushisa enkompolo ifinyelela umkhawulo kuya + 200 ° C, kuba evuthayo 250 ° C akunconywa ngoba polymer libhujiswa ukuxhumana.

Okwamanje uveza amamaki ezahlukene compounds, ngalinye elikwazi ithole nobukhulu bayo possesses izakhiwo ejwayelekile ngakho.

Adume kakhulu baba epoxy kwakwakhe - polymer ukuncipha ongaphakeme, kakhulu Kwe-dielectric Heating izici adhesion okusezingeni eliphezulu. Kuyinto bakwazi ukusebenza nemibandela ukusonteka unomphela. Epoxy inhlaka kabanzi ezihlukahlukene imishini, ukufaka, izakhiwo. Lezi zithako kukhona iyahambisana nezinye oligomers futhi ukusheshisa ukuqina yabo ngokuxuba nezinye izingxube zamakhemikhali. I ethile ye epoxy resin kuyinto yokusebenza lokushisa ongaphakeme, okuyinto eyenza kungenzeki ukuziyisa ukuyisebenzisa inqubo esebenza ngendlela izimo kunalokho nokhahlo.

Finyeta, singasho ukuthi ukusetshenziswa compounds kwandisa nokwethenjelwa tekusebenta futhi usinika ukuphila service of zobuchwepheshe futhi zikagesi, kuqinisekisa kubekwe uphawu futhi isivikelo vibration zabo, kusiza ukuvikela abathengi kusukela kagesi.
