Zofunikira zaOgulitsa PCBmabwalo ozungulira

1.Kuthumba liyenera kukhala ndi thanzi labwino

Omwe amatchedwa Stonebialincelity amatanthauza magwiridwe antchito a alloy kuti zitsulo zikuluzikidwa ndipo wogulitsira amatha kupanga kuphatikiza bwino pa kutentha koyenera. Sikuti zitsulo zonse zimakhala ndi thanzi labwino. Zitsulo zina, monga Chromium, Molbdenum, tungsten, etc., alibe chidwi kwambiri; Zitsulo zina, monga mkuwa, mkuwa, etc., kukhala ndi thanzi labwino. Mukamacheza, kutentha kwakukulu kumayambitsa kanema wa oxide kuti apange pazinthu zachitsulo, zomwe zimakhudza kuthyika kwa zinthuzo. Pofuna kusintha wosuta fodya, kupanga timina tining, kugwiritsa ntchito siliva ndi njira zina kungagwiritsidwire ntchito kupewa maxianation.

2.Mupangiri uyenera kukhala woyera

Kuti mukwaniritse kuphatikiza bwino katswiri ndi makondedwe, kuwotcherera kumtunda kuyenera kukhala koyera. Ngakhale ma trodukitala othamanga, mafilimu okutira ndi mafilimu omwe amavulaza kunyowa amatha kunyowetsa pamwamba pa mafutawo chifukwa chosungira kapena kuipitsidwa. Kanema wa dothi uyenera kuchotsedwa asanatchere, apo ayi mtundu wotentha sungatsimikizidwe. Zovala zofatsa maxidi pamimba zachitsulo zitha kuchotsedwa ndi flux. Mitundu yazitsulo yokhala ndi makuti oxidation oyimitsa ayenera kuchotsedwa ndi njira zamakina kapena mankhwala, monga kusaka kapena kunyamula.

3.sezani flux yoyenera

Ntchito ya flux ndikuchotsa kanema wa oxide pamwamba pa mafutawo. Njira zotsirizira zosiyanasiyana zimafunikira ma fluxes osiyanasiyana, monga Nickel-chromium - chitsulo chosapanga dzimbiri, aluminiyamu ndi zinthu zina. Ndikosavuta kubzala popanda wodzipereka. Mukachedwa kupenda zinthu zamagetsi zamagetsi monga mabatani a madera osindikizidwa, kuti apangitse kuwotcha kodalirika komanso kokhazikika, nthiti yochokera ku Flux nthawi zambiri imagwiritsidwa ntchito. Nthawi zambiri, mowa umagwiritsidwa ntchito kusungunuka rosin mpaka ku Rosin.

4. Kutentha kuyenera kutentha kutentha

Mukamacheza, ntchito ya mafuta amafuta ndikusungunula wogula ndikuwotcha chinthucho, kuti ma atomu ndi otsogola amapeza mphamvu zokwanira kumetedwa. Ngati kutentha kwa kutentha kumakhala kotsika kwambiri, zidzakhala zowononga kale ku maatomu a msirikali, zomwe zimapangitsa kuti zikhale zosatheka kupanga cholocha, ndipo ndizosavuta kupanga mdani wabodza. Ngati kutentha kwa kutentha kumakhala kwakukulu kwambiri, wogulitsayo adzakhala m'malo osakhala a elutectic, akuthamangitsa kuwonongeka kwa chimfine, ndikupangitsa kuti msirikali aziwonongeka, komanso m'malo oopsa, amatha kuyambitsa mapepala osindikizira kuti agwe. Zomwe zimafunikira kuti zitsimikizidwe kuti si msilikali wokhayo amene ayenera kusungunuka kuti asungunuke, koma kufuluma kuyeneranso kutenthetsedwa ndi kutentha komwe kumatha kusungunula wogula.

5. Nthawi Yosachedwa

Nthawi yotentha imanena kuti nthawi yosintha mwakuthupi komanso yamankhwala nthawi yonse yolankhula. Zimaphatikizaponso nthawi yoti zitsulo ziwonekere kuti ifikire kutentha, nthawi yosungunuka ya msirikali, nthawi ya flux kuntchito komanso nthawi ya chitsulo chochita. Pambuyo potchera kutentha kumatsimikiziridwa, nthawi yovomerezeka iyenera kutsimikiziridwa molingana ndi mawonekedwe, chilengedwe, ndi mikhalidwe ya ziwalozo kuti ziwomeredwe. Ngati nthawi yolankhulayo ndi yayitali kwambiri, zigawo zikuluzikulu kapena magawo owuma aziwonongeka mosavuta; Ngati nthawi yolankhula ndi yochepa kwambiri, zofuna kuwotcha sizikwaniritsidwa. Nthawi zambiri, nthawi yayikulu ya msirikali yolumikizidwa kuti imeke sikumapitilira masekondi 5.
