Hoʻohana Huahana

Hoʻohana nui ʻia ka MTHPA ma ke ʻano he lāʻau lapaʻau no nā resins epoxy. He haʻahaʻa haʻahaʻa kona e hoʻomohu i ka makū mai ka lewa a me ka ʻole a i ʻole ka liʻiliʻi o ka hoʻokumu ʻana o carbon dioxide ke hui pū ʻia me nā amine accelerators tertiary.

Hiki ke hoʻohui maʻalahi ʻia ka MTHPA me nā resins wai like ʻole e hāʻawi ana i ka hui paʻa, haʻahaʻa haʻahaʻa a me ke ola o ka ipuhao lōʻihi.

Hoʻohana nui ia no:

− Ka hoolei ana

− Impregnation

− Lamina

Ma ke kahua o ka plastics i hoʻoikaika ʻia, hoʻohana ʻia ia no nā huahana ʻeha filament (paipu no ka aila, pole a me nā waiwai haʻuki), nā pepa laminated, nā papa kaapuni paʻi, nā mea hoʻololi.

Mahalo i kāna mau waiwai insulating maikaʻi loa, ua loaʻa iā MTHPA nā noi he nui no ka hana ʻana i nā ʻāpana uila e like me: capacitors, resistors, wiring parts transformers, ignition coils, fly back transformers.

ʻO ka Methyltetrahydrophthalic anhydride (MTHPA) he pūhui kemika i hāʻule ma lalo o ka māhele o nā anhydride cyclic. Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻōla i nā resins epoxy. Eia kekahi mau pono nui o MTHPA:
1.Curing waiwai: ʻO MTHPA kahi mea lapaʻau maikaʻi no nā resins epoxy, e hāʻawi ana i ka wela maikaʻi a me ke kū'ē kemika. Kōkua ia i ka hoʻololi ʻana i ka resin epoxy wai i mea paʻa, lōʻihi, a me ka thermoset, kūpono ia no nā noi like ʻole.
2.Low viscosity: ʻO ka MTHPA maʻamau ka haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me nā mea hoʻōla ʻē aʻe, e maʻalahi ai ka lawelawe ʻana a hui pū me nā resins epoxy, e hoʻomaikaʻi ana i ka hana ʻana a me nā hiʻohiʻona noi.
3. ʻO ke kūpaʻa wela maikaʻi: ʻO ka epoxy i hoʻōla ʻia me MTHPA e hōʻike ana i ke kūpaʻa wela maikaʻi, e kūpono ana i nā noi kahi e pono ai ke kūpaʻa wela.
4..Nā waiwai uila maikaʻi: ʻO nā resins epoxy i hoʻōla ʻia me MTHPA ʻoiai ʻo ka mea hoʻōla e loaʻa pinepine i ka uila makemake.

Hoʻopili

Packaging: pahu galvanized 220 kg nui ma ke noi ʻana i nā ʻano ʻāpana ʻē aʻe hiki ke loaʻa.

E mālama ʻia: pono e mālama ʻia mai nā lapalapa ahi a i ʻole nā ​​kumu hoʻāla ʻē aʻe, a pono e pale ʻia mai ka makū no ka mea, ʻoi aku ka PI a me 600 mana, maʻalahi ka crystallize i ka wā e hoʻopili ai me ka ea ea. I ke kau hoʻoilo hiki ke paʻa ka MTHPA, hiki ke hoʻoheheʻe ʻia me ka hoʻomehana wale ʻana.

Ola ola: 12 mahina mai ka lā hana.

Waihona Huahana a me ka halihali ana

Inā ʻaʻole i kuhikuhi ʻia, pono e mālama ʻia nā huahana MTHPA ma kahi maloʻo, ʻoluʻolu a me ka maʻa. Hoʻohana maikaʻi ʻia i loko o 12 mau mahina ma hope o ka lā hana. Pono lākou e noho i loko o kā lākou waihona mua a hiki i ka wā ma mua o ka hoʻohana ʻana. Kūpono nā huahana no ka lawe ʻana ma ke ala o ka moku, kaʻaahi, a kaʻa paha.
