Yadda ake zaɓar safar hannu na nitrile marasa halogen? Safofin hannu na nitrile marasa halogen na Lijiejing sune zaɓin da aka fi so.

Safofin Hannu na Lijiejing marasa Halogen suna cimma cikakken iko kan abun cikin halogen ta hanyar tsarin rufewa sau uku na "sarrafa zaɓin kayan tushe, sarrafa daidaiton tsarin samarwa, da kuma gwada daidaiton samfurin da aka gama." Matakan musamman sun haɗa da: Zaɓin Kayan Tushe: Kawar da gabatarwar halogen a matakin kayan ta hanyar zaɓar latex mai ƙarancin halogen/halogen, tabbatar da abun cikin halogen ≤150ppm. Kulawa Mai Tsauri na Zaɓin Ƙari: Duk ƙarin abubuwa, gami da wakilai masu lalata da masu hanzartawa, an zaɓe su ne daga nau'ikan da ba su da halogen, masu aminci ga muhalli, kamar tsarin vulcanization marasa halogen. Duk da cewa waɗannan ƙarin abubuwa masu kyau ga muhalli suna da farashi mai girma, suna hana shigar halogen a tushen. Kulawa Mai Daidaita Samarwa: Inganta hanyoyin polymerization a duk lokacin samarwa don rage ragowar halogen. Daidaita yanayin zafi, matsin lamba, da tsawon lokacin amsawa yayin polymerization na emulsion. Yin amfani da dabarun polymerization da aka tsara don rage samfuran hydrocarbon masu halogen - kodayake yana ƙara yawan amfani da makamashi, wannan yana rage yawan halogen sosai. Ingantaccen Wankewa da Tsaftacewa: Latex bayan an yi amfani da shi wajen haɗa ruwan wanke-wanke sau 3-5 da kuma rabuwar centrifugal. Ruwan da aka cire daga jiki yana cire sauran monomers da ƙarin halogen da suka rage sosai, wanda ya zarce ƙa'idar wanke-wanke ta 1-2 ga safar hannu ta yau da kullun. Ana amfani da fasahar busar da ƙananan zafin jiki (≤90°C) ko busar da injin tsotsa don hana lalacewar abu da samuwar halogen da ke haifar da yanayin zafi mai yawa, yana tabbatar da daidaiton ƙimar halogen. Daidaitaccen sarrafa siga na wanke-wanke na chlorine: Abubuwan da ke cikin sinadarin chlorine a cikin ruwan wanke-wanke an iyakance su ga 350-600 ppm, tare da sarrafa tsawon lokacin wankewa a minti 0.3-1, yana daidaita ingancin tsaftacewa tare da haɗarin halogen da ya rage. Gwaji Mai Daidaitawa: Sakin Biyayya na Rukunin-da-Rukunin Yana kafa tsarin gwaji mai inganci wanda aka sanye da chromatographs na ion, na'urorin auna haske na X-ray, da sauran kayan aiki. Yana gudanar da nazarin adadi na abubuwan da ke cikin chlorine (Cl) da bromine (Br) a cikin kowane rukuni, yana cimma iyakokin ganowa a matakin ppm ko ma gano alamun ppb. Bin ƙa'idodin ƙasashen duniya sosai yana tabbatar da bin ƙa'idodin IEC da RoHS: sinadarin chlorine (Cl) da bromine (Br) ƙasa da 900 ppm kowanne, jimillar sinadarin halogen ƙasa da 1500 ppm, tare da wasu samfuran da suka kai jimillar matakan halogen ƙasa da 50 ppm ko ƙasa da haka.
