HALS UV-3853 ishoma molecular huremu inodzivirira amine photostabilizer, ine hunhu hwekuenderana kwakanaka, kuderera kuderera, kupararira kwakanaka uye kukurumidza kwemavara. Zviri nani kugadzikana kwechiedza, kuramba hupfu uye yero, isiri-chepfu uye yakaderera volatility; kugarisana kwakanaka; hapana ruvara rwepeji; hapana kutama. Iine yakakwira molecular uremu light stabilizer uye ultraviolet absorber, iyo synergistic mhedzisiro yakakosha.
Inonyanya kukodzera: PP, PE, PS, PU, ABS, TPO, POM, HIPs, zvigadzirwa zvinosanganisira: sandara sirika, jekiseni kuumba, kuvhuvhuta kuumba, etc., TPO uye styrene mapurasitiki.
Yakakurudzirwa kuwedzera huwandu: kazhinji 0.1-3.0%. Miedzo yakakodzera ichashandiswa kuona huwandu hwakakodzera hwakawedzerwa mukushandiswa kwacho.
Yakarongedzwa mu20kg kana 25 Kg / katoni. Kana kurongedzwa sezvinodiwa nevatengi.
Kuchengetedza:
Chengetedza muimba yekuchengetera inotonhorera, ine mhepo.
Tembiricha yekuchengetera haifanirwe kudarika 37°C.
Inofanira kuchengetwa zvakasiyana kubva kune oxidants uye makemikari anodyiwa, uye haafaniri kusanganiswa.
Chengetedza mudziyo wakavharwa.
Ramba kure nemoto nekupisa.
Midziyo yekudzivirira mheni inofanira kuiswa mudura.
Usashandise midziyo uye midziyo inogona kukonzera sparks.
Nzvimbo yekuchengetera inofanirwa kuve nemidziyo inobvinza yekukurumidzira yekurapa uye yakakodzera midziyo yekuchengetera.
Ndapota taura nesu kune chero magwaro ane hukama.
New Venture Enterprise yakazvipira kupa yepamusoro-mhando HALS kusangana nezvinodiwa zvakasiyana zvemaindasitiri aya, kutyaira hunyanzvi uye kusimba mukuvandudza zvigadzirwa, ndapota taura nesu:
