Hoʻohana
He hui organik ka 4,4'-Diamino-3,3'-dichlorodiphenylmethane (MOCA), a penei nā ala noi nui:
- Hana ʻia nā Mea Polyurethane: He mea hoʻolōʻihi kaulahao koʻikoʻi ʻo MOCA no nā elastomers polyurethane. I ka hana ʻana o ka polyurethane, pono nā prepolymers isocyanate e hana me nā mea hoʻolōʻihi kaulahao e hana i nā polymers polyurethane kaumaha molekala kiʻekiʻe. Loaʻa iā MOCA kahi reactivity kiʻekiʻe me nā isocyanates, hiki ke hoʻolōʻihi pono i ke kaulahao molekala polyurethane a hoʻomaikaʻi i ka paʻakikī, ka ikaika, ke kūpaʻa ʻana i ke komo ʻana, ke kūpaʻa ʻana i ka haehae a me nā waiwai ʻē aʻe o ka mea. Hoʻohana pinepine ʻia ia i ka hana ʻana i nā huahana elastomer polyurethane e halihali ana i nā ukana kiʻekiʻe, e like me nā papa sieve, nā wili rubber, nā sila, a me nā mea ʻē aʻe i hoʻohana ʻia i nā ʻoihana e like me ke kālai ʻana, ka metallurgy, a me ka petroleum. Pono kēia mau huahana i ke kūpaʻa ʻana i ke komo ʻana a me nā waiwai mechanical.
- ʻĀkena Hoʻōla no nā Resins Epoxy: Hiki ke hoʻohana ʻia ʻo MOCA ma ke ʻano he ʻākena hoʻōla no nā resins epoxy. Ke hele nei ia i kahi hopena hoʻopili ʻana me nā resins epoxy e hana i kahi ʻano pūnaewele ʻekolu-dimensional, no laila e hoʻōla ai i nā resins epoxy. Loaʻa i nā resins epoxy i hoʻōla ʻia nā waiwai mechanical maikaʻi, ke kūpaʻa i ka palaho kemika, a me ke kūpaʻa wela. Hoʻohana pinepine ʻia ia i ka hana ʻana o kekahi mau composites epoxy me nā koi hana kiʻekiʻe, e like me nā kahua o nā mea ipu uila a me nā uhi papahele. Pono nā mea ipu uila e pale i nā ʻāpana uila kūloko mai ke kaiapuni waho. Hiki i ka resin epoxy i hoʻōla ʻia me ke komo ʻana o MOCA ke hāʻawi i ka sila maikaʻi a me ka pale mechanical. Pono nā uhi papahele Epoxy i nā waiwai e like me ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa i ka palaho e hoʻokō i nā koi hoʻohana o nā wahi e like me nā hale hana ʻoihana a me nā wahi kaʻa.
ʻŌpala a me ka Hoʻouna ʻana
25KG/ʻeke a i ʻole e like me nā koi a ka mea kūʻai aku.
Hoʻouna: 6.1 ʻano waiwai weliweli a hiki ke hoʻouna ma ke kai.
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
