Tshebetso e tsoileng matsoho ea theipi ea mica

As the main raw material of fire-resistant cables, mica tape should have its product standards. The technical conditions for the specified performance indicators and test methods of mica tape products fully reflect the objective and practical needs. It is necessary for the electrical performance of mica tape to be assessed at the same time by the two indicators of insulation resistance value and withstand voltage at high temperature. Due to the large variety of fire-resistant cables, the entire insulation system (including conductor-to-conductor and conductor-to-shielding systems) ) There are certain requirements. When the insulation resistance drops to a certain value, even if there is no insulation breakdown, the entire circuit system will lose its normal operation function. For the quality of fire-resistant cables, the quality of mica tape is the key to its “fire-resistant” function.

Mica theipi e na le mocheso o phahameng oa ho hanyetsa mocheso le ho hanyetsa mollo. Mica theipi e na le maemo a matle tlasa maemo a tloaelehileng mme e loketse moalo o ka sehloohong o sa keneleng mollo oa likhoele le mehala e sa keneleng mollo. Kaha theipi ea mica e sebelisa pente e khomarelang ea silicone e nang le tšebetso e ntle haholo joalo ka sekgomaretsi, ha ho na mosili o kotsi ha o chesoa mollong o bulehileng. Ka hona, theipi ea mica ha e sebetse feela bakeng sa lithapo le likhoele tse sa keneleng mollo, empa hape e bolokehile haholo.

theipi ea mica e ka fihlela tse ling tsa litlhoko tsa ho kenya motlakase oa li-motor tse nang le matla a phahameng haholo, ka hona e sebelisoa haholo. Ka keketseho ea boemo ba motlakase oa makoloi, ntlafatso e tsoelang pele ea bokhoni le nts’etsopele e tsoelang pele ea ts’ebetso e phahameng, litlhokahalo tsa ho kenya motlakase oa koloi le tsona li ntlafalitsoe khafetsa, mme lipatlisiso mabapi le lisebelisoa tse tsamaellanang le tsona li ntse li tsoela pele. Theipi ea mica e entsoe ka pampiri ea mica joalo ka lihlahisoa tse tala, ‘me mahlakore a mabeli kapa a le’ ngoe a entsoe ka lesela la motlakase le nang le alkali le filimi ea polyester kapa filimi ea polyimide kapa filimi e hananang le corona joalo ka lisebelisoa tse matlafatsang . Ho latela sebopeho, e arotsoe ka: theipi ea mahlakore a mabeli, theipi e sekametseng lehlakoreng le le leng, theipi e le ‘ngoe, theipi e habeli ea filimi, theipi ea filimi e le’ ngoe, jj Ho latela mica, e ka aroloa ka: theipi ea maiketsetso ea mica , theipi ea phlogopite, le theipi ea muscovite.

Mollo o ka etsahala kae kapa kae, empa ha mollo o hlaha sebakeng se nang le baahi ba bangata le litlhoko tse phahameng tsa polokeho, ho bohlokoa haholo ho netefatsa hore likhoele tsa motlakase le tlhaiso-leseling li boloka ts’ebetso e tloaelehileng bakeng sa nako e lekaneng, ho seng joalo e tla baka kotsi e kholo. Ka hona, likhoele tse sa cheng mollo tse hlahisitsoeng ka theipi ea mica li sebelisoa haholo libakeng tse latelang: liforomo tsa ho cheka oli, meaho e phahameng, liteishene tse kholo tsa motlakase, literene tse tsamaeang ka tlas’a lefatše, likhoebo tsa bohlokoa tsa indasteri le tsa meepo, litsi tsa likhomphutha, litsi tsa lifofane, litsi tsa tlhaiso-leseling ea puisano, lits’ebeletso tsa sesole, le likhoebo tsa bohlokoa tsa indasteri le tsa merafo Tse amanang le polokeho ea mollo le pholoso ea mollo. Mica theipi e na le ts’ebetso e ntle haholo le ts’ebeliso e bonolo ebile e fetohile sesebelisoa sa likhoele tse sa cheng.
