Ungayikhetha kanjani impahla ye-mica board insulation yokukhiqiza abagibeli

Ibhodi le-commutator mica, elibizwa nangokuthi i-commutator mica board, ingenye yezinto ezibaluleke kakhulu zokuvikela ama-DC motors. Kunezinto ezimbili ezibalulekile zokukhiqiza ibhodi le-mica ye-commutator: eyodwa iyishidi le-mica lendawo encane, kanti enye iyi-powder mica paper. Ukuze wenze umkhiqizo ufinyelele ubukhulu obudingekayo, ipuleti le-mica elenziwe ngamashidi e-mica kufanele ligaywe noma lipholishwe. Uma ucindezela, izinhlangothi ezimbili zihlanganiswe nephepha elihlukile le-liner kanye ne-canvas, ukuze ubukhulu bufanane futhi ukuqina kwangaphakathi kufinyelelwe ngemva kokucindezela. Lapho i-powder mica paper isetshenziselwa ukwenza i-powder mica board, uma isimo sokucindezela sisihle, inqubo yokugaya noma yokugaya ingashiywa.

Ngaphezu kwalokho, ngokuya ngamazinga ahlukene wokufakwa kwemoto, kanye nezidingo zokumelana ne-arc kanye nomswakama, i-shellac, upende we-polyester, upende we-melamine polyacid, i-ammonium phosphate aqueous solution, i-cyclic resin glue noma upende oguquliwe we-silicone kusetshenziswa njengezinamatheliso. khiqiza Izinhlobo ezahlukene zamabhodi e-mica.

Ukusetshenziswa kwe-shellac kungakhiqiza amapuleti e-mica e-commutator angafinyelela izinga lokushisa lika-100 ° C nangaphezulu, kufaka phakathi amapuleti amafu e-commutator ama-motor anesivinini esikhulu. Kodwa okubi ukuthi ukusebenza kahle kokukhiqiza kuphansi.

Kungcono kune-shellac ukusebenzisa i-polyacid resin ehlanganiswe ku-ortho-jasmonic anhydride ne-glycerin. Kulula ukucwecwa nokunamathisela amashidi e-mica, futhi kungenza futhi inqubo yokunamathisela amashidi e-mica, ukuze inani elikhulu labanikazi bezindlu likwazi ukukhiqiza amabhodi e-mica e-commutator. . Kodwa-ke, okungalungile ukuthi kukhona i-resin e-unpolymerized ebhodini le-mica, futhi ukuchithwa kwe-resin ebhodini le-mica kuqiniswa ngaphansi kwethonya lokushisa eliphezulu nokucindezela okukhulu. ebusweni bomshayeli wemoto.

Uma usebenzisa ipuleti le-polyacid resin commutator mica njengenjini yokushisa okuphezulu ukuze kuvikelwe isihambisi se-traction crane noma injini enkulu, kufanele ishiselwe ngaphambi kokusetshenziswa. Ngemuva kokwenza kanjalo, lapho ucindezela i-commutator, ukuphuma kwe-resin kuzoncishiswa, okuqinisekisa nokuthembeka kwe-commutator ekusebenzeni.

Ukusetshenziswa kwe-Anfu powder njenge-adhesive kungenza ukusebenza kwebhodi le-commutator mica kungashintshi ngaphansi kwezimo zomswakama ophezulu kanye nezinga lokushisa (200 ℃ noma ngaphezulu). Izinga layo lokushwabana lincane kunamanye amabhodi e-mica, futhi ukumelana kwayo nezinga lokushisa eliphakeme lidlula ku-600 ℃. Ngakho-ke, ikhwalithi yayo ngokuvamile iphakeme kunamabhodi e-mica ashiwo ngenhla, futhi ububanzi bohlelo lokusebenza nalo lubanzi.

Ibhodi le-mica elenziwe nge-epoxy noma i-melamine ne-polyacid resin inokumelana okuhle kwe-arc futhi isetshenziswa kumamotho we-DC anesivinini esikhulu.

Ibhodi le-mica elenziwe nge-organic resin eguquliwe lingamelana nezinga lokushisa eliphakeme futhi lisetshenziswa kumamotho wokugeleza akhethekile.

I-NIDE ihlinzeka ngamabhodi e-mica ahlukahlukene kanye nabagibeli, asetshenziswa kakhulu emkhakheni wamathuluzi kagesi, ama-brushless motors, amamotho ezimoto zamandla amasha, izinto zasendlini, amatafula okuphakamisa, imibhede yemishini yezokwelapha kanye neminye imikhakha.
