Ndizodziwika kwa makasitomala kufanizira zotenthetsera za mphira za silikoni ndi chotenthetsera cha polyimide, chomwe chili bwino?
Poyankha funsoli, tapanga mndandanda wazinthu zamitundu iwiriyi ya ma heaters kuti tifananize, tikukhulupirira kuti izi zingakuthandizeni:
A. Insulation layer ndi kutentha kukana:
1. Zowotchera mphira za silikoni zimakhala ndi chotchinga chopangidwa ndi zidutswa ziwiri za nsalu za mphira za silicon zokhala ndi makulidwe osiyanasiyana (nthawi zambiri zidutswa ziwiri za 0.75mm) zomwe zimakhala ndi kutentha kosiyana. Nsalu ya rabara ya silikoni yotumizidwa kunja imatha kupirira kutentha mpaka madigiri 250 Celsius, ndikugwira ntchito mosalekeza mpaka madigiri 200 Celsius.
2. Poyimidi Kutenthetsa PAD ndi kutchinjiriza wosanjikiza wopangidwa ndi zidutswa ziwiri za polyimide filimu ndi makulidwe osiyana (nthawi zambiri zidutswa ziwiri za 0.05mm). Yachibadwa kutentha kukana wa polyimide filimu akhoza kufika madigiri 300 Celsius, koma silikoni utomoni zomatira TACHIMATA pa polyimide filimu ali ndi kutentha kukana yekha 175 digiri Celsius. Choncho, kutentha kwakukulu kwa kutentha kwa heater ya polyimide ndi madigiri 175 Celsius. Kukaniza kutentha ndi njira zoyikamo zithanso kusiyanasiyana, chifukwa mtundu wotsatiridwa umangofikira madigiri 175 Celsius, pomwe kukonza kwamakina kumatha kukhala kokwera pang'ono kuposa madigiri 175 Celsius.
B. Kapangidwe kazinthu zotenthetsera mkati:
1. Zomwe zimatenthetsa mkati mwazitsulo zopangira mphira za silicone nthawi zambiri zimakonzedwa pamanja mawaya a nickel-chromium alloy. Kugwiritsa ntchito pamanja kumeneku kungapangitse kuti pakhale kusiyana kosiyana, zomwe zingakhudze kutenthetsa mofanana. Kuchuluka kwamphamvu kwamphamvu ndi 0.8W/square centimita. Kuphatikiza apo, waya umodzi wa nickel-chromium alloy amatha kuyaka, zomwe zimapangitsa kuti chotenthetsera chonsecho chisagwire ntchito. Chinthu chinanso chotenthetsera chimapangidwa ndi mapulogalamu apakompyuta, owonekera, ndi okhazikika pamapepala a iron-chromium-aluminium alloy etched sheets. Kutentha kwamtunduwu kumakhala ndi mphamvu zokhazikika, kutembenuka kwamafuta ambiri, kutentha kwa yunifolomu, komanso malo otalikirana, okhala ndi mphamvu zambiri zofikira 7.8W/square centimeter. Komabe, ndi okwera mtengo.
2. Chotenthetsera chamkati cha polyimide filimu chotenthetsera nthawi zambiri chimapangidwa ndi mapulogalamu apakompyuta, owonekera, ndi kuzikika pazitsulo zachitsulo-chromium-aluminium alloy etched sheets.
C. Makulidwe:
1. Kuchuluka kwazitsulo zopangira mphira za silicone pamsika ndi 1.5mm, koma izi zikhoza kusinthidwa malinga ndi zofuna za makasitomala. Kukhuthala kwa thinnest kumakhala kozungulira 0.9mm, ndipo kukhuthala kumakhala pafupifupi 1.8mm.
2. The makulidwe muyezo wa polyimide Kutentha PAD ndi 0.15mm, amene angathenso kusintha malinga ndi zofuna za makasitomala.
D. Kupanga:
1. Zowotchera mphira za silicone zimatha kupangidwa mu mawonekedwe aliwonse.
2. Chotenthetsera cha polyimide nthawi zambiri chimakhala chathyathyathya, ngakhale chomalizidwacho chili mu mawonekedwe ena, mawonekedwe ake apachiyambi akadali athyathyathya.
E. Makhalidwe ofanana:
1. Magawo ogwiritsira ntchito mitundu yonse iwiri ya ma heaters amaphatikizana, makamaka malinga ndi zomwe wogwiritsa ntchito amafuna komanso mtengo wake kuti adziwe kusankha koyenera.
2. Mitundu yonse iwiri ya ma heaters ndi zinthu zotentha zomwe zimatha kupindika.
3. Mitundu yonse iwiri ya heaters ili ndi kukana kwabwino kovala, kukana kukalamba, komanso kutsekereza katundu.
Mwachidule, zotenthetsera mphira za silicone ndi chotenthetsera cha polyimide zili ndi mawonekedwe awo komanso zabwino zawo. Makasitomala amatha kusankha chotenthetsera choyenera kwambiri potengera zosowa zawo.
