Ukusebenza ngokugqwesileyo kwetape 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.

I-Mica tape ine-resistance ephezulu yeqondo lokushisa kunye nokuxhatshazwa komlilo. I-Mica tape inokuba bhetyebhetye okuhle phantsi kweemeko eziqhelekileyo kwaye ilungele ungqameko oluphambili lokuchasana nomlilo lweentambo ezahlukeneyo kunye nezintambo. Kuba iteyiphu ye-mica isebenzisa ipeyinti yokuncamathela kwe-silicone enentsebenzo egqwesileyo njengokubambelela, akukho bungozi bokuba ngumsi xa utshisiwe kwilangatye elivulekileyo. Ke ngoko, iteyiphu ye-mica ayisebenzi kuphela kwiingcingo ezingatshi emlilweni kunye neentambo, kodwa ikhuselekile kakhulu.

Iteyiphu ye-mica inokuhlangabezana neemfuno ezithile zokugquma kwee-motors eziphezulu, ngoko ke isetyenziswa ngokubanzi. Ngokunyuka kwenqanaba levolthi yemoto, ukuphuculwa okuqhubekayo komthamo kunye nokukhula okuqhubekayo kokusebenza okuphezulu, iimfuno zokugquma kweemoto nazo ziyaphuculwa ngokuqhubekekayo, kwaye nophando lwezixhobo zokugquma ezihambelanayo nazo ziyaqhubeka. Iteyiphu ye-mica yenziwe ngephepha le-mica njengezinto ezingavuthiyo, kwaye amacala aphindwe kabini okanye amacala abodwa ngokwahlukeneyo enziwe ngombala weglasi ongenanto ye-alkali kunye nefilimu ye-polyester okanye ifilimu ye-polyimide okanye ifilimu enganyangekiyo njengeziqinisa izinto ngenkqubo ekhethekileyo . Ngokwesakhiwo, yahlulwe: itape enamacala amabini, iteyiphu emacala-nye, iteyiphu emacala-mabini, itheyiphu yefilimu ephindwe kabini, iteyiphu enye yefilimu, njl. , i-phlogopite tape, kunye ne-muscovite tape.

Umlilo unokwenzeka naphi na, kodwa xa umlilo uvela kwindawo enabantu abaninzi kunye neemfuno eziphezulu zokhuseleko, kubaluleke kakhulu ukuqinisekisa ukuba amandla kunye neentambo zolwazi zigcina ukusebenza kwesiqhelo ixesha elaneleyo, kungenjalo kuya kubangela ingozi enkulu. Ke ngoko, iintambo ezingangenwa ngumlilo eziveliswa nge-mica tape zisetyenziswa kakhulu kwezi ndawo zilandelayo: amaqonga okumba i-oyile, izakhiwo eziphakamileyo, izitishi zamandla amakhulu, iindlela zangaphantsi, amashishini abalulekileyo emizi-mveliso kunye nezimbiwa, amaziko ekhompyuter, amaziko eenqwelo moya, amaziko olwazi onxibelelwano, amaziko ezomkhosi, kunye namashishini abalulekileyo amashishini kunye nezemigodi ahambelana nokhuseleko emlilweni kunye nokuhlangula umlilo. I-Mica tape inentsebenzo egqwesileyo kunye nokusetyenziswa okufanelekileyo kwaye iye yaba yinto yeentambo ezingatshiyo.
