Machubu otenthetsera kutentha amapangidwa ndi ma polima apamwamba kwambiri, omwe amapangidwa mwasayansi ndikusakanikirana mwamakina kukhala aloyi ya polima, kenako amawunikiridwa ndi accelerator ya elekitironi kuti alumikizane ndikukulitsa mosalekeza pambuyo pakuwumba.Mankhwalawa ali ndi ubwino wa chitetezo cha chilengedwe, chofewa, chowotcha moto, kuchepa mofulumira, kugwira ntchito mokhazikika ndi zina zotero.Amagwiritsidwa ntchito kwambiri polumikizana ndi mawaya, chitetezo cholumikizana ndi solder, malekezero a waya, ma waya ndi zida zamagetsi zoteteza ndi kutchinjiriza, waya ndi zolembera zina.
Pali njira zitatu zomwe zimagwiritsidwa ntchito kwambiri kutenthetsa machubu ocheperako: chopepuka, mfuti yotentha, ndi uvuni.
Choyamba ndi chopepuka.
Choyatsira ndi chida chathu chotenthetsera chomwe timakonda kugwiritsa ntchito, koma kutentha kwakunja kwalawi kumafika madigiri masauzande ambiri, komwe kumakhala kokulirapo kuposa kutentha kwa chubu chocheperako, chifukwa chake tiyenera kulabadira kusuntha uku ndi mtsogolo tikamagwiritsa ntchito. chopepuka kuphika, kotero kuti chubu chotenthetsera kutentha chitenthedwe mofanana lonse kuti chisawotche chubu chowotcha kutentha kapena kupanga mawonekedwe a chubu chowotcha kutentha kukhala choyipa.Koma zenizeni, nthawi zambiri sitingathe kuwongolera kutentha kwa choyatsira ndikuwotcha mosavuta chubu chocheperako, chifukwa chake tikulimbikitsidwa kugwiritsa ntchito zida zotenthetsera zaukadaulo.
Njira yachiwiri ndiyo kugwiritsa ntchito mfuti yamoto.
Mfuti yamoto ndi chida chotenthetsera chaukadaulo, koma kutentha kwamfuti komwe kumagwiritsidwa ntchito nthawi zambiri kumatha kufika 400 ℃, kugwiritsa ntchito mfuti yamoto sikungathe kuwotcha chubu chowotcha, koma tiyenera kupitiriza kugwedeza mfutiyo ndikubwerera. kupitirira, kotero kuti kutentha shrinkable chubu ndi wogawana kutentha lonse kuonetsetsa mawonekedwe a kutentha shrinkable chubu pambuyo kuchepa.Tsegulani kutentha mfuti, preheat gawo lonse la chinthu kukhala ndi kutentha shrinkable chubu, ndi Kutentha ayenera kukhala yunifolomu, kuti kutentha kwa chinthu ndi apamwamba kuposa yozungulira kutentha, pafupifupi 60 ℃;Ikani utali wokwanira wa manja pa chinthucho, ndipo valani magolovesi oteteza pamene mukugwira ntchito kuti musapse ndi kutentha.Gwiritsani ntchito mfuti yotenthetsera kutentha kwa chubu chowotcha, kutentha kuyenera kutenthedwa pang'onopang'ono komanso mofanana kuchokera kumapeto mpaka kumapeto, kapena kuchokera pakati mpaka malekezero onse awiri, ndikoletsedwa kutentha kuchokera ku malekezero onse mpaka pakati, kuti mupewe thovu. ndi bloating;Pakakhala kupindika pakuwotha, kupindika kwamkati kuyenera kutenthedwa poyamba, ndiyeno kupindika kwakunja kuyenera kutenthedwa, komwe kungapewe makwinya a chubu chotenthetsera kutentha komwe kumapindika;Potentha, mfuti yamoto iyenera kusuntha mofanana kuti casing ikhale yotentha, ndipo kutentha kwa m'deralo sikuyenera kukhala kwakukulu, zomwe zimachititsa kuti chubu chotenthetsera chitenthe kapena kuzizira;Mukatenthetsa, chubu chowotcha chikazizira, gwiritsani ntchito mpeni wamagetsi kuti muchepetse kutentha kwa chubu pamphuno ngati pakufunika, ndipo pojambula choyikapo, mphamvuyo isakhale yayikulu kwambiri kuti musawononge chinthucho.Pambuyo pokonza, ngati pali madontho pamwamba pa chubu chowotcha kutentha, chiyenera kupukuta ndi chiguduli cha mowa.
Chomaliza ndi uvuni.
Chiwerengero cha kutentha kutentha shrink machubu ndi lalikulu, ndipo tikulimbikitsidwa kugwiritsa ntchito uvuni.Kutentha kwabwino kwa shrinkage kwa machubu a shrinkage kuyenera kukhala 125 ± 5 ° C, pamwamba pa kutentha uku, ngati kusakaniza kosakhazikika kumayikidwa mu uvuni, pamakhala chiopsezo chomamatira ndikupangitsa kuti chinthucho chisweke.Choncho, powotcha ng'anjo, tcherani khutu ku makonzedwe a yunifolomu ndipo musaunjike pamodzi, kuti musayambitse mavuto omwe ali pamwambawa.Tsegulani uvuni, sinthani kutentha kukhala pafupifupi 60 °C ~ 70 °C, ndipo tenthetsani gawo lonse la chinthucho kuti chikhazikitsidwe ndi chubu chotenthetsera kutentha kwa mphindi zisanu;Chotsani chinthu chotenthetsera mu uvuni, ikani chubu chotenthetsera chautali woyenerera pa chinthucho, ndipo valani magolovesi oteteza pamene mukugwira ntchito kuti musawotche.Malinga ndi zomwe zimaperekedwa ndi kutentha shrinkable chubu wopanga, pambuyo kusankha yoyenera kutentha ndi Kutentha nthawi, ntchito ng'anjo kutentha kutentha shrinkable chubu, kulabadira zinthu anaika mu uvuni sayenera kudzaza kwambiri, kuti kupewa. kutentha shrinkable chubu kutentha kuchepetsa mphamvu chifukwa cha kutentha shrinkage zotsatira si zabwino;Kutentha kukatha, chubu lotha kutentha likazizira, gwiritsani ntchito mpeni wamagetsi kuti mudule chubu chomwe chimatha kutentha pamiyendo monga momwe mungafunire, ndipo pokanda choyikapo, mphamvuyo isakhale yayikulu kwambiri, kuti musawononge chinthu;Pambuyo pokonza, ngati pali madontho pamwamba pa chubu chowotcha kutentha, chiyenera kupukuta ndi chiguduli cha mowa.
