Tungsten carbide strip inonyanya kugadzirwa neWC tungsten carbide uye Cobalt poda yakavhenganiswa nesimbi nzira nekuputika, kugaya bhora, kudzvanya uye sintering, iwo makuru alloy zvikamu WC uye Co, zvirimo muWC neCo mukushandiswa kwakasiyana kwetungsten carbide strip. hazvina kufanana, uye kushandiswa kwemhando yakakura kwazvo.
Chimwe chezvinhu zvakanyanya zve tungsten carbide mitsetse, inodanwa nekuda kwechimiro chayo chekona yemahwendefa (kana masikweya), anozivikanwawo se tungsten carbide strip/plates. Tungsten carbide strip ine kuomarara kwakanyanya, yakanaka kupfeka kuramba, yakakwira elastic modulus, yakakwirira compressive simba, yakanaka kugadzikana kwemakemikari (asidi, alkali, yakanyanya tembiricha oxidation kuramba), kusimba kwekushomeka, kuderera kwekuwedzera kwekuwedzera, kupisa uye magetsi conductivity yakafanana nesimbi uye yayo. alloys.
Ndezvipi zvikonzero zvedesolderingye tungsten carbide strips? Chuangrui carbide anopindura zvinotevera:
(1) Iyo tungsten carbide inopenya haina kuchekwa kana kukwenenzverwa isati yaiswa, uye iyo oxide layer iri pamusoro pebrazing inoderedza kunyorova kwesimbi yekubhuroka uye inonetesa kusimba kwekubatana kweweld.
(2)Desolderingichaitikawo kana iyo brazing agent isina kusarudzwa uye yakashandiswa zvisina kunaka, semuenzaniso, kana borax inoshandiswa seyakagadzika, iyo borax haigone kuita basa re deoxidizing nekuti iyo borax ine hunyoro hwakawanda, uye iyo brazing zvinhu haigone kunyorova. pamusoro pechiso chendarira, uyedesolderingchiitiko chinoitika.
(3) Tembiricha chaiyo yekubhura inofanira kunge iri 30 ~ 50 °C pamusoro penzvimbo inonyunguduka yesimbi inopenya, uyedesolderingzvichaitika kana tembiricha yakanyanya kana kuderera. Kupisa zvakanyanya kunogona kukonzera oxidation mune weld. Kushandisa zinc-ine brazing simbi ichapa weld ruvara rwebhuruu kana chena. Kana kupisa kwekupisa kwakanyanyisa, weld yakanyanyisa ichaumbwa, uye mukati meweld ichafukidzwa neporosity uye slag inclusions. Mamiriro maviri ari pamusoro apa achaderedza kusimba kweweld, uye zviri nyore kudhiza kana yakarodzwa kana kushandiswa.
(4) Muchigadziro chekugadzirisa, hapana nguva ye slag discharge kana kusakwana kwe slag discharge, kuitira kuti yakawanda ye brazing agent slag inoramba iri mu weld, iyo inoderedza simba re weld uye inokonzera.desoldering.
