Magolovesi a nitrile amagawidwa makamaka malinga ndi kuyera kwa zipangizo zopangira, katundu weniweni, ukadaulo wopangira zinthu ndi zochitika zoyenera, ndi zina zotero. Njira zodziwika bwino zogawira ndi izi:
I. Yogawidwa malinga ndi chiyero cha zipangizo zopangira ndi kuchuluka kwa zinthu zodetsedwa
- Magolovesi a nitrile a mafakitale
◦ Mulingo wa nitrile mu zinthu zopangira ndi wochepa (nthawi zambiri 60%-80%), zodzaza zambiri, zofewetsa ndi zina zowonjezera zidzawonjezedwa, ndipo kuchuluka kwa zonyansa (monga ma ayoni achitsulo, ma monomers otsala) ndi okwera.
◦ Yoyenera kugwiritsidwa ntchito m'mafakitale (monga kukonza makina, kuyeretsa), yokhala ndi zofunikira zoyambira zolimbana ndi kupsinjika, kukana mafuta ndi dothi, koma osati ukhondo wofunikira kwambiri, chiopsezo cha ziwengo, ndi zina zotero.
- Magolovesi a Nitrile a Zachipatala/Chakudya Chokwera
◦ Kuyera kwambiri kwa mphira wa nitrile (≥80%), kuwongolera mosamalitsa mitundu ndi mlingo wa zowonjezera, palibe zowonjezera zomwe zimayambitsa khansa, komanso kuchuluka kochepa kwa zodetsa (monga zinthu zochotsedwa, ma index a tizilombo toyambitsa matenda mogwirizana ndi miyezo yoyenera, monga zofunikira za US FDA, EU CE).
◦ Kugwirizana bwino kwa zinthu zachilengedwe, sikumayambitsa ziwengo mosavuta, koyenera kuwunika kwachipatala, kukonza chakudya ndi zina zomwe zimafunikira kwambiri kuti munthu akhale waukhondo komanso wotetezeka.
Chachiwiri, malinga ndi zizindikiro za magwiridwe antchito
- Magolovesi a nitrile amphamvu wamba
◦ Mphamvu ya kung'ambika nthawi zambiri imakhala pakati pa 15-25kN/m, mphamvu yokoka 10-20MPa, kutalika 400%-600%, yoyenera kugwiritsidwa ntchito tsiku ndi tsiku (monga ntchito zapakhomo, ntchito zamafakitale zochepa).
- Magolovesi amphamvu a nitrile
◦ Mphamvu yong'ambika ≥25kN/m, mphamvu yokoka ≥20MPa, kutalika ≥600%, zinthu zina zimakonzedwa bwino pogwiritsa ntchito njira (monga kuwonjezera kuchuluka kwa ma cross-linking) kapena kapangidwe kokhuthala, kukana kukwawa ndi kukana kubowoka zimakonzedwa bwino kwambiri, zoyenera ntchito zamphamvu kwambiri monga zomangamanga, kupanga magalimoto ndi makampani opanga mankhwala.
III. Kugawidwa ndi ntchito yapadera ndi njira
- Magolovesi a nitrile opanda ufa
◦ Chotsani ufa pogwiritsa ntchito njira monga chithandizo cha maikulosikopu yamagetsi, kutsuka ndi chlorine, ndi zina zotero kuti mupewe kuipitsidwa ndi fumbi komanso chiopsezo cha ziwengo, pogwiritsa ntchito zinthu zapamwamba kwambiri, zomwe zimagwiritsidwa ntchito kwambiri m'malo oyera monga zamankhwala, zamagetsi, labotale, ndi zina zotero.
- Magolovesi a nitrile osagonjetsedwa ndi mankhwala
◦ Gwiritsani ntchito rabara ya nitrile yokhala ndi acrylonitrile yambiri (30%-40% ya acrylonitrile, kuchuluka kwake kukakhala kwakukulu, kukana mafuta kumakhala kolimba), kukana bwino zinthu zosungunulira zachilengedwe, ma acid ndi alkali ndi mankhwala ena, ndi gawo la zinthu zodzitetezera zaukadaulo.
- Magolovesi a nitrile oletsa kusinthasintha kwa mpweya/otulutsa mpweya
◦ Onjezani antistatic agent kapena conductive material, control surface resistance pa 10⁶-10¹¹Ω (antistatic) kapena 10⁴-10⁶Ω (conductive), yoyenera kupanga zamagetsi, semiconductors ndi zochitika zina zolondola zokhudzana ndi static, grade ya material iyenera kukwaniritsa muyezo wa antistatic (monga ISO 14644).
Chachinayi, malinga ndi gawo la satifiketi ya muyezo wa mafakitale - Kutsatira miyezo yachipatala (monga EN 455, ASTM D6319): kufunikira kupitilira mayeso a tizilombo toyambitsa matenda, kuyesa kwa cytotoxicity, ndi zina zotero, zofunikira pamlingo wazinthu ndizokhwima, kuti zitsimikizire chitetezo cha kukhudzana ndi thupi la munthu kapena zinthu zachipatala. - Kutsatira miyezo yokhudzana ndi chakudya (monga FDA 21 CFR 177.2600): Zowonjezera zoopsa ndizoletsedwa, ndipo kukana kusamuka kwa zinthuzo kumakwaniritsa muyezo, koyenera kukhudzana mwachindunji ndi chakudya. - Kutsatira miyezo yoteteza mafakitale (monga EN 374, ANSI/ISEA 105): kuyang'ana kwambiri kukana mankhwala, kukana kukanda, kukana kubowola, ndi zina zotero, ndikugawidwa m'magawo (monga magulu okana kukanda a Level 1-5) malinga ndi zosowa zosiyanasiyana za mafakitale. Mwachidule, mtundu wazinthu wa magolovesi a nitrile ndi chiwonetsero chokwanira cha "chiyero, magwiridwe antchito ndi chitetezo": mtundu wa mafakitale umayang'ana kwambiri kulimba koyambira, mtundu wa zamankhwala/chakudya umagogomezera kuyera ndi chitetezo, ndipo mtundu wapadera wa ntchito umalimbitsa magwiridwe antchito aukadaulo pazochitika zinazake. Posankha, ndikofunikira kufananiza mtundu wofanana wa zinthuzo malinga ndi momwe zimagwiritsidwira ntchito (monga ukhondo, chitetezo, anti-static, ndi zina zotero).
