Ho tloaelehile hore bareki ba bapise li-heaters tsa rabara tsa silicone le heater ea polyimide, e leng ho molemo?
Ho arabela potso ena, re hlophisitse lethathamo la litšobotsi tsa mefuta ena e 'meli ea li-heaters bakeng sa papiso, ka tšepo ea hore li ka u thusa:
A. Insulation layer le mocheso oa ho hanyetsa:
1. Licheso tsa rabara tsa silicone li na le lera la ho kenya letsoho le entsoeng ka likotoana tse peli tsa lesela la rabara la silicon le botenya bo fapaneng (hangata likotoana tse peli tsa 0.75mm) tse nang le mocheso o fapaneng oa ho hanyetsa. Lesela la rabara la silicone le tsoang kantle le ka mamella mocheso ho fihla ho likhato tse 250 tsa Celsius, ka ts'ebetso e tsoelang pele ho fihla ho likhato tse 200 tsa Celsius.
2. Letlapa la ho futhumatsa la polyimide le na le lesela la ho kenya letsoho le entsoeng ka likarolo tse peli tsa filimi ea polyimide e nang le botenya bo fapaneng (hangata likotoana tse peli tsa 0.05mm). Mocheso o tloaelehileng oa ho hanyetsa filimi ea polyimide o ka fihla likhato tse 300 tsa Celsius, empa sekhomaretsi sa resin sa silicone se koahetsoeng ka filimi ea polyimide se na le mocheso oa mocheso oa likhato tse 175 feela tsa Celsius. Ka hona, mocheso o phahameng oa ho hanyetsa mocheso oa polyimide ke likhato tse 175 tsa Celsius. Ho hanyetsa mocheso le mekhoa ea ho kenya le eona e ka fapana, kaha mofuta o khomaretsoeng o ka fihla feela ka har'a likhato tse 175 tsa Celsius, athe ho lokisa mochine ho ka ba holimo hanyenyane ho feta likhato tse 175 tsa Celsius.
B. Sebopeho sa ntho e futhumatsang ka hare:
1. Karolo ea ho futhumatsa ka hare ea li-heaters tsa rabara tsa silicone hangata li hlophisoa ka letsoho lithapo tsa nickel-chromium alloy. Ts'ebetso ena ea matsoho e ka etsa hore sebaka se se ke sa lekana, se ka bang le tšusumetso e itseng molemong oa ho futhumatsa. Boholo ba matla a matla ke 0.8W/square centimeter feela. Ho feta moo, terata e le 'ngoe ea nickel-chromium alloy e na le monyetla oa ho cha, e leng se etsang hore heater e felisoe e se na thuso. Mofuta o mong oa lisebelisoa tsa ho futhumatsa o entsoe ka software ea komporo, e pepesitsoe, 'me e kentsoe maqepheng a tšepe-chromium-aluminium alloy etched sheets. Mofuta ona oa ho futhumatsa o na le matla a tsitsitseng, phetoho e phahameng ea mocheso, mocheso o ts'oanang, le sebaka se batlang se lekana, se nang le matla a mangata a ho fihla ho 7.8W/square centimeter. Leha ho le joalo, e batla e tura.
2. Karolo e futhumatsang ea ka hare ea heater ea filimi ea polyimide hangata e entsoe ka software ea k'homphieutha, e pepesitsoe, 'me e kentsoe maqepheng a tšepe-chromium-aluminium alloy etched sheets.
C. Botenya:
1. Botenya bo tloaelehileng ba li-heaters tsa rabara tsa silicone 'marakeng ke 1.5mm, empa sena se ka fetoloa ho latela litlhoko tsa bareki. Botenya ba thinnest bo pota-potile 0.9mm, 'me botenya hangata bo pota-potile 1.8mm.
2. Botenya bo tloaelehileng ba polyimide futhumatsang pad ke 0.15mm, e ka boela ea fetoloa ho latela litlhoko tsa bareki.
D. Tlhahiso:
1. Li-heaters tsa rabara tsa silicone li ka etsoa ka sebōpeho leha e le sefe.
2. Polyimide heater ka kakaretso e bataletse, esita le haeba sehlahisoa se felileng se le sebopeho se seng, sebopeho sa sona sa pele se ntse se bataletse.
E. Litšobotsi tse tloaelehileng:
1. Mabala a ts'ebeliso ea mefuta e 'meli ea li-heaters a kopana, haholo-holo ho itšetlehile ka litlhoko tsa mosebedisi le ho nahana ka litšenyehelo ho fumana khetho e nepahetseng.
2. Mefuta e 'meli ea li-heaters ke lisebelisoa tsa ho futhumatsa tse tenyetsehang tse ka kobehang.
3. Mefuta e 'meli ea li-heaters e na le khanyetso e ntle ea ho apara, ho hanyetsa botsofali le thepa ea ho pata.
Ka kakaretso, li-heaters tsa rabara tsa silicone le heater ea polyimide li na le litšobotsi le melemo ea tsona. Bareki ba ka khetha heater e loketseng ka ho fetisisa ho latela litlhoko tsa bona tse khethehileng.
