Choyamba, pamwamba pa kulondola kwapamwambachubu chamkuwaidzapanga nsanjika yolimba yoteteza, mosasamala kanthu kuti ndi mafuta, ma carbohydrate, mabakiteriya ndi majeremusi, zamadzimadzi zovulaza, mpweya wa okosijeni kapena cheza cha ultraviolet, sichingadutsemo, komanso sichingakokoloke kuti iipitse madzi abwino, ndipo tizilombo toyambitsa matenda sitingathe kudutsamo.Sizingakhale pamwamba pa mipope yamkuwa kuti iwafewetse.Machubu amkuwa olondola kwambiri ndi olimba kuposa machubu apulasitiki, osinthika kwambiri kuposa zitsulo wamba, osavuta kukonza, komanso amalimbana ndi chisanu.Chubu chamkuwa chapamwamba kwambiri chimakhala ndi kukana kwamphamvu, zomwe zimatsimikizira kuti zimatha kugwira ntchito bwino ngakhale pansi pazovuta kwambiri popanda kupunduka kapena kusweka.
Njira yowotcherera yamkuwa nthawi zambiri imakhala kuwotcherera gasi, waya wowotcherera wamkuwa, borax.Samalani kukula kwa lawi pamene kuwotcherera.Choyamba ntchito kuwotcherera gasi kuwotcha chitoliro chamkuwa chofiira.Panthawiyi, tcherani khutu ku moto wa buluu pakati pokonza motowo, ndikusintha kuti ukhale wautali, mwinamwake kutentha kudzakhala kwakukulu ngati kuli kochepa.Onjezani borax, ndi kuwonjezera waya wowotcherera wamkuwa pambuyo poti borax itasungunuka.
Masitepe a Brass Soldering
1. Panthawi yowotcherera, nthawi zonse sungani moto wophimba mafupa kuti mpweya usalowe;
2. Madziwo adzauma, ndipo chinyezi chidzasungunuka pa 100 ° C, ndipo kutuluka kwake kudzakhala koyera ngati mkaka.
3. Flux ichita thovu pa 316 ° C.
4. Flux imakhala phala pa 427°C
5. Kuthamanga kumakhala madzimadzi pa 593 ° C, yomwe ili pafupi ndi kutentha kwa moto.
6. Solder yokhala ndi 35% -40% siliva imasungunuka pa 604 ° C ndipo imayenda pa 618 ° C.
7. Dziwani kuti zinthu ziwiri zowotcherera ziyenera kutenthedwa ndi nyali yowotcherera.
8. Mutha kuwona ngati kutentha kuli koyenera ndi mtundu wamoto.Kutentha kukafika pa kutentha kwa moto, lawi lamoto lidzawoneka lobiriwira, ndipo lawi lobiriwira lidzasonyeza kuti kutentha kuli koyenera kukafika kutentha kwa siliva.
9. Kuwotchera chitoliro chamkuwa ndi chitoliro chachitsulo kwa wina ndi mzake, chitoliro chamkuwa chiyenera kutenthedwa choyamba (chifukwa chitoliro chamkuwa chimatentha mofulumira ndipo chimafuna kutentha kwakukulu).
10. Panthawi yowotcha, nyali yowotcherera sayenera kuyima nthawi zonse, koma ikhoza kusuntha mu chithunzi chachisanu ndi chitatu.
11. Ndibwino kuti mugwiritse ntchito nyali yaikulu, kotero kuti kutentha kwakukulu kungapezeke ndi moto wofewa popanda kupanikizika kwambiri kapena "kuwomba", makamaka ndi kuwala pang'ono pamoto wamkati wa conical.
