Kugwiritsa Ntchito Mankhwala

MTHPA imagwiritsidwa ntchito makamaka ngati chothandizira kuchiritsa ma epoxy resins. Sichimakonda kuyamwa chinyezi kuchokera mumlengalenga ndipo sichimapanga mpweya woipa kwambiri ikasakanizidwa ndi ma accelerator a tertiary amine.

MTHPA ikhoza kusakanikirana mosavuta ndi ma resin osiyanasiyana amadzimadzi omwe amapereka chisakanizo chokhazikika, cholimba komanso chokhala ndi moyo wautali m'miphika.

Amagwiritsidwa ntchito kwambiri pa:

Kuponya/Kuphika m'mbale

- Kubereka mwana

− Kupaka utoto

Mu ntchito ya pulasitiki yolimbikitsidwa imagwiritsidwa ntchito popanga zinthu zomangira ulusi (mapaipi amafuta, mitengo ndi zinthu zamasewera), mapepala opangidwa ndi laminated, ma circuit board osindikizidwa, ma switch gear.

Chifukwa cha mphamvu zake zabwino zotetezera kutentha, MTHPA yapeza ntchito zambiri zopangira zida zamagetsi monga: ma capacitor, ma resistors, ma wiring parts transformers, ma ignition coils, ndi ma fly back transformers.

Methyltetrahydrophthalic anhydride (MTHPA) ndi mankhwala omwe ali m'gulu la ma cyclic anhydride. Amagwiritsidwa ntchito makamaka ngati chothandizira kuchiritsa mu ma epoxy resins. Nazi zina mwazabwino zazikulu za MTHPA:
1. Kapangidwe kake kochiritsa: MTHPA ndi mankhwala othandiza kwambiri ochiritsa ma epoxy resin, omwe amapereka kutentha kwabwino komanso kukana mankhwala. Amathandiza kusintha epoxy resin yamadzimadzi kukhala chinthu cholimba, cholimba, komanso chotenthetsera kutentha, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.
2. Kukhuthala Kochepa: MTHPA nthawi zambiri imakhala ndi kukhuthala kocheperako poyerekeza ndi zinthu zina zophikira, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito ndikusakaniza ndi ma epoxy resins, zomwe zimapangitsa kuti ntchito yake ikhale yabwino komanso yogwiritsidwa ntchito bwino.
3. Kukhazikika bwino kwa kutentha: Epoxy yokonzedwa bwino yokhala ndi MTHPA imakhazikika bwino pa kutentha, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito komwe kukana kutentha ndikofunikira.
4..Makhalidwe abwino amagetsi: Ma resini a epoxy okonzedwa okhala ndi MTHPA monga chothandizira kuchiritsa nthawi zambiri amakhala ndi magetsi abwino.

Kulongedza

Kupaka: ng'oma yokhala ndi galvanized yolemera makilogalamu 220 ngati mutapempha, pali njira ina yopaka.

Kusungirako: kuyenera kusungidwa kutali ndi malawi otseguka kapena malo ena oyatsira moto, ndipo kuyenera kutetezedwa ku chinyezi chifukwa, makamaka PI ndi mitundu 600, imauma mosavuta ikakhudzana ndi chinyezi cha mpweya. M'nyengo yozizira MTHPA imatha kuuma, imatha kusungunuka mosavuta pongotenthetsa.

Alumali moyo: miyezi 12 kuyambira tsiku lopanga.

Kusunga ndi Kuyendera Zinthu

Pokhapokha ngati patchulidwa mwanjira ina, zinthu za MTHPA ziyenera kusungidwa pamalo ouma, ozizira komanso osanyowa. Ndi bwino kugwiritsa ntchito mkati mwa miyezi 12 kuchokera tsiku lopangidwa. Ziyenera kukhalabe m'mapaketi awo oyambirira mpaka nthawi yoti zigwiritsidwe ntchito. Zinthuzo ndizoyenera kutumizidwa kudzera m'sitima, sitima, kapena galimoto.
