1.3 Ke kaumaha kikoʻī: 1.2
1.4 Hoʻoheheʻe ʻia: Hoʻoheheʻe ʻia i loko o ka benzene, ether a me ka acetone. Hoʻoheheʻe iki ʻia i loko o ka ethanol. ʻAʻole hoʻoheheʻe ʻia i ka wai.
1.5 Kikowaena paila: 220-225 ℃, 0.5mmHg
1.6 Paʻa a me ka pane ʻana: Hiki ke lapalapa. Ke hōʻike ʻia i ka lewa a i ʻole ka lā, e hoʻopau ʻia ka huahana a hoʻololi i kona kala. Ke hoʻopili ʻia me ka waikawa hydrochloric wela, lilo ia i ʻōmaʻomaʻo.
1.7 Nā Waiwai: ʻO ka oxidation o nā hui latex a me ka rubber e pili ana i ke ʻano o ka polymer i komo. ʻO nā pilikia e pili ana i nā loli kala maikaʻi ʻole, ka nalowale o ka maʻalahi, ka nalowale o ka ikaika tensile a me ka emi ʻana o ke kūpaʻa hopena, ka ʻelemakule, ka haki ʻana a me nā ʻino ʻili ʻē aʻe. Hāʻawi nā antioxidants Rubber i ka hana koʻikoʻi a me ka pale ʻana i nā noi e like me ka rubber a me nā plastics, e pale ana i nā polymers mai ka hoʻohaʻahaʻa oxidative ma muli o ka wela, ka mālamalama, ka mae ʻana o ke kinoea, nā peroxides, ka shear, a me nā mea hoʻololi ʻē aʻe. Hāʻawi ka DPPD antioxidant H i ka paʻa wela lōʻihi a me ke kūpaʻa kala; he pono ia i ka ʻiliʻili, fiber, a me nā ʻāpana ʻāpana mānoanoa; a hana maikaʻi i nā ʻōnaehana i hoʻopiha ʻia.

Hiki ke hoʻohana ʻia ka Antioxidant H/DPPD ma ke ʻano he antioxidant i loko o ka propellant paʻa e hoʻomaikaʻi i ke kūpaʻa o ka mālama ʻana o ka huahana. Ua hoʻohana ʻia no kēlā mau mea kūlohelohe, styrene-butadiene, acrylonitrile-butadiene, butadiene, butyl, hydroxyl, polyisoprene rubber e loaʻa ka hana e like me ke ola flex maikaʻi a me ka crazing no ka hoʻonui ʻana i ka modulus tensile, hoʻoikaika i ka hana pale i ka oxygen wela, ozone a me kekahi mau metala ʻino e like me ke keleawe, manganese me ka ʻole o ka mana i ka vulcanization o kēlā mau rubbers. Hiki iā ia ke hoʻoponopono i ka pilikia ʻelemakule e kū nei i loko o nā huahana rubber hohonu-kala ʻoiai e hoʻohana ʻia ka antioxidant H me ka antioxidant D. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa oxygen wela no kēlā mau plastics ʻenekinia e like me ka polyethylene, polypropylene, polyamide, polyformaldehyde e hoʻomaikaʻi i kā lākou hana kū i ke aniau.
Hoʻohana: 1) Hoʻohana ʻia ka Antioxidant H/DPPD (N,N'-Diphenyl-p-phenylenediamine) ma ke ʻano he antioxidant a me ka mea hoʻopaʻa no ka laholio, nā aila petroleum a me nā mea hānai. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea hoʻopaʻa polymerization a me kahi mea pale i ka hoʻohaʻahaʻa keleawe. He mea hoʻohui kemika ia e hana i nā dyes, nā lāʻau lapaʻau, nā plastics, a me nā mea hoʻohui detergent.
2) Hoʻohana pū ʻia ka Antioxidant H/DPPD i ka hana ʻana o nā polyolefins paʻa kala ʻole a me nā kiʻiʻoniʻoni PVC a me PVB.
3) Hoʻohana nui ʻia ka Antioxidant H/DPPD i ka hapa nui o nā lattices a me nā rubbers kūlohelohe a me synthetic.
Hoʻopili ʻana:ʻEke ulana i uhi ʻia me ka ʻeke palakiko, ʻo ke kaumaha ʻupena he 20 kg/ʻeke.
Ka mālama ʻana:Mālama ʻia i kahi wahi anuanu a ea. ʻO ke ola o ka papa he 12 mau mahina ma hope o ka lā hana. Loaʻa nō ia inā kūpono ka hopena o ka hoʻāʻo hou ʻana ma hope o ka lā pau
Nā kuhikuhi palekana:ʻAihue. Pono e hoʻohana i nā mīkina lima laholio, ka mea hanu a me ka pale maka i ka wā o nā hana inā pili ka ʻili, pili nā maka.
Ka halihali:E pale i ka ua, ka ʻike ʻana, ke kiʻekiʻe o ka mahana.
