Ungasarudza sei magirovhosi asina halogen? Magirovhosi eLijiejing asina halogen ndiwo anonyanya kufarirwa.

Magorovhosi eLijiejing Halogen-Free Nitrile anowana kudzora kwakasimba kwezviri mukati mehalogen kuburikidza nehurongwa hwe "kudzora kusarudzwa kwezvinhu zvinobva, kudzora maitiro ekugadzira, uye kuyedzwa kwakarurama kwechigadzirwa." Matanho chaiwo anosanganisira: Kusarudzwa kweZvinhu Kubva: Bvisa kuiswa kwehalogen pachidanho chezvinhu zvisina kugadzirwa nekusarudza low-halogen/halogen-free nitrile latex, kuve nechokwadi chekuti huwandu hwehalogen huri ≤150ppm. Kudzora Kwakasimba kweKusarudzwa kweKuwedzera: Zvese zvinowedzerwa, kusanganisira zvinokuvadza uye zvinomhanyisa, zvinosarudzwa kubva kumhando dzisina halogen, dzine hushamwari nenharaunda, dzakadai semasisitimu evulcanization asina halogen. Kunyange zvazvo izvi zvinowedzerwa zvine hushamwari nezvakatipoteredza zvine mitengo yakakwira, zvinodzivirira kuiswa kwehalogen pachinobva. Kudzora Kwakanaka Kwekugadzira: Kugadzirisa maitiro epolymerization mukati mekugadzirwa kwese kuderedza masara ehalogen. Kudzora tembiricha, kumanikidzwa, uye nguva yekuita panguva ye emulsion polymerization. Kushandisa nzira dzepolymerization dzakarongwa kuderedza halogen hydrocarbon byproducts - kunyangwe zvichiwedzera kushandiswa kwesimba, izvi zvinoderedza zvakanyanya huwandu hwehalogen. Kushambidzwa Kwakawedzerwa uye Kucheneswa: Latex yePost-polymerization inosangana nenzira yakabatana yekushambidzwa kwemvura kwematanho matatu kusvika mashanu + kupatsanurwa kwecentrifugal. Mvura yakabviswa ion inobvisa zvakakwana mamonomer e halogen akasara uye zvimwe zvinowedzera, zvichipfuura mwero wekushambidzwa we1-2 wemagirovhosi akajairwa. Tekinoroji yekuomesa yakaderera (≤90°C) kana kuomesa vacuum inoshandiswa kudzivirira kuora kwezvinhu uye kuumbwa kwe halogen compound kunokonzerwa nekupisa kwakanyanya, zvichiita kuti halogen ive yakasimba. Kudzora kwakaringana kwe chlorine washing parameter: Chlorine iri mumushonga wekushambidza inogumira pa350-600 ppm, uye nguva yekushambidza inodzorwa pa0.3-1 miniti, ichienzanisa kushanda kwekuchenesa nengozi ye halogen yakasara. Kuedza Kwakaringana: Kuburitswa Kwemitemo yeBatch-by-Batch Kugadzira sisitimu yekuyedza yakanyatsonaka ine ma ion chromatographs, X-ray fluorescence spectrometers, nezvimwe zvishandiso. Inoita ongororo yehuwandu hwe chlorine (Cl) uye bromine (Br) mubatch yega yega, ichiwana miganhu yekuona pa ppm level kana kunyange ppb-level trace identification. Kunyatsotevedzera mitemo yepasi rose kunovimbisa kutevedzera mirairo yeIEC neRoHS: huwandu hwechlorine (Cl) nebromine (Br) huri pasi pe900 ppm imwe neimwe, huwandu hwehalogen huri pasi pe1500 ppm, zvigadzirwa zvakasarudzwa zvichisvika huwandu hwehalogen hwakaderera se50 ppm kana pasi.
