Kodi mungasankhe bwanji magolovesi a nitrile opanda halogen? Magolovesi a nitrile opanda halogen a Lijiejing ndi omwe amakondedwa kwambiri.

Magolovesi a Lijiejing Halogen-Free Nitrile amakwaniritsa kulamulira kolimba kwa zinthu za halogen kudzera mu dongosolo lotsekedwa katatu la "kuwongolera kusankha zinthu zomwe zimachokera, kuwongolera molondola njira zopangira, ndi kuyesa kolondola kwa zinthu zomwe zatsirizidwa." Njira zinazake ndi izi: Kusankha Zinthu Zomwe Zimachokera: Kuchotsa kuyambitsa kwa halogen pagawo la zopangira posankha latex ya halogen yopanda halogen/halogen, kuonetsetsa kuti kuchuluka kwa halogen kuli ≤150ppm. Kuwongolera Kolimba kwa Kusankha Zowonjezera: Zowonjezera zonse, kuphatikiza zinthu zovulcanizing ndi zothamangitsa, zimasankhidwa kuchokera ku mitundu yopanda halogen, yosamalira chilengedwe, monga machitidwe a halogen opanda vulcanization. Ngakhale zowonjezerazi zachilengedwe zimakhala ndi ndalama zambiri, zimaletsa kuyambitsa kwa halogen pa gwero. Kuwongolera Kolondola kwa Kupanga: Kukonza njira zopopera polima panthawi yonse yopanga kuti muchepetse zotsalira za halogen. Kuwongolera bwino kutentha, kuthamanga, ndi nthawi yochitapo kanthu panthawi ya emulsion polymerization. Kugwiritsa ntchito njira zopopera polima zokhazikika kuti muchepetse zinthu za halogen zomwe zimapangidwa ndi hydrocarbon - ngakhale zikuwonjezera kugwiritsa ntchito mphamvu, izi zimachepetsa kwambiri kuchuluka kwa halogen. Kutsuka ndi Kuyeretsa Kowonjezereka: Latex yopangidwa pambuyo pa polymerization imadutsa mu njira yophatikizana ya kutsuka madzi kwa magawo atatu mpaka asanu + kulekanitsidwa kwa centrifugal. Madzi oyeretsedwa amachotsa bwino ma halogen monomers otsala ndi zowonjezera, zomwe zimaposa muyezo wa kutsuka wa 1-2 wa magolovesi wamba. Ukadaulo wouma wotentha pang'ono (≤90°C) kapena kuumitsa vacuum umagwiritsidwa ntchito popewa kuwonongeka kwa zinthu ndi kupanga kwa halogen komwe kumachitika chifukwa cha kutentha kwambiri, kuonetsetsa kuti halogen imakhala yokhazikika. Kuwongolera kolondola kwa magawo otsukira a chlorine: Kuchuluka kwa chlorine mu yankho lotsukira kumakhala kochepera 350-600 ppm, ndipo nthawi yotsuka imayendetsedwa pa mphindi 0.3-1, kulinganiza bwino kuyeretsa ndi chiopsezo chotsalira cha halogen. Kuyesa Kolondola: Kutulutsidwa kwa Batch-by-Batch Compliance Kukhazikitsa njira yoyesera yolondola kwambiri yokhala ndi ma ion chromatographs, ma X-ray fluorescence spectrometers, ndi zida zina. Amachita kusanthula kuchuluka kwa chlorine (Cl) ndi bromine (Br) mu gulu lililonse, kukwaniritsa malire ozindikira pamlingo wa ppm kapena ngakhale kuzindikira kwa ppb-level trace. Kutsatira kwambiri miyezo yapadziko lonse lapansi kumaonetsetsa kuti zinthu zonse za chlorine (Cl) ndi bromine (Br) zikutsatira malangizo a IEC ndi RoHS: chlorine (Cl) ndi bromine (Br) zili pansi pa 900 ppm iliyonse, halogen yonse ili pansi pa 1500 ppm, ndipo zinthu zina zomwe zasankhidwa zimafika pa 50 ppm kapena kuchepera.
