Yassi kism 125 kengaitirilgan. Vertical kism 122 11-kismning vertical kism 112. Yani 11-kismning vertical kismi 121 va boshka kismning 12-vertical kismi 122 bir-biriga tegib turadi.
Terminalni oina sirtiga elektr kontakti sifatida kavshirlanganda oina va kashirlash kushimcha materialarini issyklikdan kengayish koieficienti turlicha bulganligi sababli kontakt vakt utishi bilan kucishi mumkin. Bu kamchilikni tuzatishni usullaridan biri kavshirlash materialarini tarkibini tadkikotlar asosida tugri tanlashdir.
Tadkikotlarni natijalaridan maylumki, kavshirlash sifati (degrodatsiyasiga) kullaniladigan flux tartibi va tarkibiga ham boglik. Flux bilan kaita ishlangan maidon 3 dan 20:1 nisbat munosabatida bulishi kerak. Bundan tashkent kavshrlashdan oldin surtilgan flux kavshirlashdan keyin tozalab tashlanmaidi. Kavshirlash natijalarini samaradorligiga kullanilaetgan flux tarkibiga ham boglik.
Kupchilik tadkikotlarni kursatisic kavshirlash kushimcha materiali sirt zichligi mikdori 0.18 dan 1.43 g/cm 2 oralikda yahshi natija beradi. Oina sirtiga terminalni kavshirlash temperaturasi 20-200°From oralikda buladi.
Yahshi natija bergan tadkikotlarda kavshirlash kushimcha materiali Sn-Zn (kalai-rukh) tarkibda Zn ulisha mass 8% ni tashkil etadi.
Misol uchun Sn-Zn soldering iron temperaturasi 260° C eki 320° C bulganda sifatli kavshirlash amalga oshadi. Metal chikish (electrode) 1 mis eki latun elementni oz ichiga oladi. Kavshirlash kushimcha materialini 113 va 123 sirtlarda sirt zichligi 1,18 g/cm 2 ni tashkil etadi.
Kavshirlash technolgiyasini oinaga tasirini aniklash maksadida mahsus ketma ketlikda tazhribadar utkazilgan.
Issyklik davri sinovi ҳar bir namuna uchun tsiklni takrorlash orkali amalga oshirildi, u 30 daka davomida -30° C da saklangan va keyin bir cycle sifatida 30 daka davomida 80° C da saklanadi. Bundan tashkari, tsiklni takrorlash zharaenida shisha taglikdagi yeriklar paydo bylishi bevosita kyz bilan kuzatilgan va yeriklar paydo bylishini kuzatishda yeriklar paydo bylishidan oldin takrorlangan tsiklar sonisoblangan.
2-zhadvalda ushbu ihtironing kavshirlash usuli bilan ishlab chikarilgan namunalar (misollar) va kiesiy misollar uchun isitish davri sinovining natijalari kyrsatilgan. Issyklik davrlari sony 300 dan kam bilgan va shisha tagida yeriklar paido bilgan ҳolat "X" bilan, thermal davrlar sony 300 va undan kyp bilgan ҳolat "◯" bilan kyrsatilgan.
2-zhadvaldan kirinib turibdiki, metal kyrgoshin materiali electrodi latun bilgan kiyoshi misolda, soldering ironing ҳarorati 310° C eki 260° C, flux maidoni nisbati 3 dan kam. Birlik uchun kavshirlash kushimcha materiali sirte zichligi 0,14 dan 1,18 g/cm 2 oraligida bilsa, barcha namunalar thermal cyclda 300 martadan kichik bulgan holdayek yerlib ketgan.
Ikkinchi tomondan, metal metal chikish electrodi latun bilgan namunadagi misolda, payalnikning ҳarorati 260° C eki 320° C, birlik maidoni uchun kotishma sirte zichligi 1,18 g / cm2, flux maidoni. 4,5, 18 va 20 nisbatlaring ҳar kandayida thermal davrlar sony 300 martadan oshdi va maҳsulot mukammal sifatga ega ekanligi tasdiklandi. Ainiksa, flux maidoni nisbati 20 ga teng bulgan namunali misolda, shisha taglik 3000 With eki undan ortik isitish davrlaridan keyin ҳam yerlib ketmaydi va sifati judah yahshi.
Hulosa. Keltirib utilgan takhlilii materiallardan hulosalash mumkinki, avtolarni oynalarini elektr energiyasi orkali kizdirish tizimini tashkil etish buyicha judah kup ilmiy izlanishlar olib borilgan. Bu ilmiy izlanish natijalari fakat ilmiy patentlar orkali mualliflashtirilgan. Ilmiy natijalar ochik ilmiy journalarda elon kilnmagan. Buning sababi, tadkikotlar mavzulari avtovil sanoatiga talukligi va mavzularni fakat hizmat foidalanishi ("chipboard" for service use) grifida bulganligidir.
Ilmiy tadkikotlar takhlili kursatadiki, metal kontaktlarni (terminallarni) but metal materiallarga kavshirlashda anik technologik talablarga etibor karatish lozim. Birinchi navbatda kavshirlash kushimcha materiali tarkibi keltiribulgan tarkibda bulishi, ikkinchidan kavshirlashda kavshirlash maidonini flux bilan kaita ishlash maidoni kashirlash maidonidan kamida 3 marotaba katta bulishi, uchinchidan kavshirlashni anik temperature intervalida amalga oshirilishi kerak.
