I-ejenti yokuhlanza esekelwe emanzini ST-300.
incazelo yomkhiqizo
Sethula i-ST-300 yokuhlanza amanzi evumelana nemvelo, isisombululo esiguquguqukayo semboni yezogesi. Le ejenti yokuhlanza enamandla ayifani nanoma iyiphi enye emakethe, njengoba ayinazo izincibilikisi ezinobuthi ezinobuthi noma ama-asidi angaphili ne-alkali. Eqinisweni, icishe ingathathi hlangothi, okuyenza ibe inketho ephephile futhi ezinzile yezidingo zokuhlanza izimboni.
I-ejenti yokuhlanza i-ST-300 yakhiwe ngama-surfactants akhethekile ahlukahlukene, okuyenza ibe enye yezindlela ezingcono kakhulu zama-agent okuhlanza asekelwe ku-solvent evame ukusetshenziswa embonini ye-electronics. Akugcini nje ngokuhlinzeka ngomphumela omuhle kakhulu wokuhlanza ezinsalela ze-flux kanye ne-solder paste, kodwa futhi ingasetshenziswa ukuhlanza amaketanga e-wave soldering, izinto ezilungiswayo, insimbi yensimbi, nokuningi. Le ejenti yokuhlanza enemisebenzi eminingi ishintsha umdlalo ezinkampanini ezifuna ukuthuthukisa izinqubo zazo zokuhlanza kuyilapho zehlisa umthelela wazo kwezemvelo.
Esinye sezici ezibalulekile ze-ejenti yokuhlanza i-ST-300 iphunga layo eliphansi, okuwushintsho olwamukelekayo kubasebenzi abavame ukubhekana nephunga lamakhemikhali elinokhahlo ezindaweni zezimboni. Lokhu kwenza indawo yokusebenza ibe mnandi futhi enethezekile, kuyilapho iletha ukusebenza okukhethekile kokuhlanza.
Ngaphezu kwalokho, i-ejenti yokuhlanza i-ST-300 iqhosha ngomthwalo ophezulu wokuhlanza, okusho ukuthi ingabhekana ngokuphumelelayo nemisebenzi yokuhlanza enzima ngaphandle kokudinga ukushintshwa njalo. Lokhu akugcini nje kongi isikhathi nemali kodwa futhi kunciphisa imfucuza, kukwenze kube ukukhetha okusimeme emabhizinisini athintekayo mayelana nendawo yawo yemvelo.
Ngaphezu kwalokho, impilo ende yesevisi ye-ejenti yokuhlanza i-ST-300 isho ukuthi izinkampani zingathembela kuyo ekuhlanzeni okungaguquki, okusezingeni eliphezulu esikhathini eside. Lokhu kunciphisa isidingo sokushintshwa kwemikhiqizo njalo, kuyenze ibe yisixazululo esingabizi kakhulu samabhizinisi abo bonke osayizi.
Sekukonke, i-ejenti ye-ST-300 yokuhlanza amanzi evumelana nemvelo iyindlela ehlukile kuneyendabuko yokuhlanza esekelwe ku-solvent. Amandla ayo okuhlanza anamandla, ahlanganiswe nephunga layo eliphansi, umthamo womthwalo wokuhlanza ophezulu, nokuphila kwesevisi ende, akwenza kube ukukhetha okuhle ezinkampanini ezifuna ukuthuthukisa izinqubo zazo zokuhlanza kuyilapho zibeka phambili ukusimama kwemvelo.
Kungakhathaliseki ukuthi ukumboni yezogesi noma esinye isilungiselelo semboni esidinga ukusebenza kokuhlanza okuphezulu, i-ejenti yokuhlanza ye-ST-300 ishintsha igeyimu. Valelisa iphunga lamakhemikhali elinamandla nezithako ezinobuthi, futhi sawubona ikusasa elihlanzekile, eliluhlaza ngesisebenzeli sokuhlanza se-ST-300.

Ukusetshenziswa kanye Nokugcinwa
1. Isetshenziselwa kakhulu ukuhlanza i-residual soldering flux kumabhodi e-PCB, amaketanga e-wave soldering, izinto ezilungiswayo, ukuhlanzwa kwe-steel mesh solder paste, njll.
2. Kungcono kakhulu ukusebenzisa ukushisa kwe-ultrasonic kuya ku-45-80℃ ukuze uthole imiphumela engcono.
3. Ngemva kokuhlanza nge-ST-300, kungcono ukugeza kahle ngamanzi.
