Kodi epoxy galasi fiber ndodo ili ndi poizoni?

Mapuloteni a epoxy ndi zomatira za epoxy resin siopanda poizoni, koma chifukwa chakuwonjezera kwa zosungunulira ndi zinthu zina za poizoni pokonzekera, ma resin ambiri a epoxy ndi “poizoni”. M’zaka zaposachedwa, makampani opanga epoxy resin akutengera kusinthidwa kwamadzi kuti apewe Kuphatikiza ndi njira zina zosungitsira utomoni wa epoxy “wopanda poizoni.” Pakadali pano, zokutira zambiri za epoxy resin ndizopangira zosungunulira, zomwe zimakhala ndi mankhwala osakanikirana ambiri (VOC), omwe ndi owopsa komanso oyaka moto, motero amawononga chilengedwe komanso thupi la munthu.

Utomoni wa epoxy umagwiritsidwa ntchito limodzi ndi zowonjezera kuti mupeze phindu. Zowonjezera zimatha kusankhidwa kutengera zolinga zosiyanasiyana. Zowonjezera zomwe amagwiritsidwa ntchito ndimatundu awa: (1) wothandizira; (2) kusintha; (3) kudzaza; (4) kuchepa; ena.

Kodi epoxy galasi fiber ndodo ili ndi poizoni? Mwa iwo, wothandizira wochiritsa ndi wowonjezera. Kaya imagwiritsidwa ntchito ngati zomatira, zokutira, kapena zotayika, ziyenera kuwonjezeredwa ndi wothandizira, apo ayi utomoni wa epoxy sungachiritsidwe. Mafinya a epoxy nthawi zambiri amatanthauza mankhwala opangidwa ndi ma polima omwe amakhala ndi magulu awiri kapena kupitilira apo a molekyulu. Kupatula owerengeka, kuchuluka kwawo kwama molekyulu sikokwanira. Kapangidwe ka maselo a epoxy resin amadziwika ndi gulu la epoxy lomwe limagwira ntchito mndende. Gulu la epoxy limatha kupezeka kumapeto, pakati kapena munthawi yazoyanjana zamagulu. Chifukwa mawonekedwe ake amakhala ndimagulu a epoxy, atha kulumikizana ndi mitundu ingapo yamankhwala ochiritsa kuti apange ma polima osasungunuka komanso osasunthika okhala ndi ma network atatu.

Magwiridwe ndi mawonekedwe a epoxy resin

1. Mitundu yosiyanasiyana. Ma resin osiyanasiyana, othandizira kuchiritsa, ndi makina osinthira amatha kusintha kutengera zofunikira zosiyanasiyana pafomuyi, ndipo mitunduyi imatha kukhala yochokera pa mamasukidwe akayendedwe otsika mpaka zolimba kwambiri.

2. Kuchiritsa bwino. Sankhani mitundu yosiyanasiyana ya othandizira akuchiritsa, dongosolo la epoxy resin limatha kuchiritsidwa pamatenthedwe a 0 ~ 180 ℃.

3. Kumangiriza mwamphamvu. Magulu abwinobwino a polar hydroxyl ndi ma ether omwe amakhala munthawi yamagulu a epoxy resin amawamatira kwambiri pazinthu zosiyanasiyana. Kuchepetsa kwa epoxy resin kumakhala kotsika pochiritsa, ndipo kupsinjika kwamkati komwe kumachitika ndikochepa, komwe kumathandizanso kukulitsa mphamvu yolumikizira.

4. Kutsika pang’ono. Zomwe zimachitika pakati pa epoxy resin ndi wothandizira omwe amagwiritsidwa ntchito zimachitika ndikuwonjezera mwachindunji kapena kutsegulira mphete magulu a epoxy mu molekyulu ya utomoni, ndipo palibe madzi kapena zinthu zina zosakhazikika zomwe zimatulutsidwa. Poyerekeza ndi ma resin a polyester osakwaniritsidwa komanso ma phenolic resins, amawonetsa kuchepa kwambiri (ochepera 2%) pakachiritsa.

5. Mawotchi katundu. Makina ochiritsidwa a epoxy resin ali ndi mawonekedwe abwino kwambiri.

6, magwiridwe antchito amagetsi. Makina ochiritsidwa a epoxy resin ndi zinthu zabwino kwambiri zotetezera zomwe zimakhala ndi ma dielectric okwera, kutayikira kwapamwamba, komanso kukana kwa arc.

7. Kukhazikika kwamankhwala. Nthawi zambiri, dongosolo lochiritsidwa la epoxy resin limakhala ndi kukana kwa alkali kwambiri, kukana kwa asidi ndi kukana zosungunulira. Monga zinthu zina za epoxy yochiritsidwa, kukhazikika kwamankhwala kumadaliranso ndi utomoni wosankhidwa ndi wothandizira. Kusankhidwa koyenera kwa epoxy resin ndi othandizira kuchiritsa kumatha kuyipangitsa kukhala ndi bata lapadera la mankhwala.

8. Kukhazikika kokhazikika. Kuphatikiza kwa zinthu zambiri pamwambapa kumapereka epoxy resin system kukhala yolimba komanso yolimba.

9, nkhungu kugonjetsedwa. Makina otetezedwa a epoxy resin amalimbana ndi nkhungu zambiri ndipo atha kugwiritsidwa ntchito m’malo otentha.
