1.3 Ike ndọda kpọmkwem: 1.2
1.4 Mmiri Na-agbaze: Na-agbaze na benzene, ether na acetone. Na-agbaze ntakịrị na ethanol. A naghị agbaze na mmiri.
1.5 Ebe esi mmiri: 220-225℃, 0.5mmHg
1.6 Nkwụsi ike na mmeghachi omume: Ọ na-ere ọkụ. Mgbe ikuku ma ọ bụ anwụ na-acha, ngwaahịa ahụ ga-agbaze ma gbanwee agba ya. Mgbe etinyere ya na acid hydrochloric dị ọkụ, ọ na-aghọ akwụkwọ ndụ akwụkwọ ndụ.
1.7 Njirimara: Oxidation nke latex na roba na-adabere n'ụdị polima dị na ya. Nsogbu ndị a gụnyere mgbanwe agba na-adịghị mma, enweghị mgbanwe, mfu nke ike nrụgide na mbelata iguzogide mmetụta, ịka nká, mgbawa na mmebi elu ndị ọzọ. Oxidation nke rọba na-enye arụmọrụ na nchebe dị mkpa na ngwa dịka roba na plastik, na-echebe polima site na mbibi oxidative n'ihi okpomọkụ, ìhè, gas na-ada ada, peroxides, shear, na ihe ndị ọzọ na-agbanwe agbanwe. Oxidation DPPD H na-enye nkwụsi ike okpomọkụ ogologo oge na nkwụsi ike agba; ọ dị irè na ihe nkiri, eriri, na ihe ndị dị arọ; ọ na-arụkwa ọrụ nke ọma na sistemụ jupụtara.

Enwere ike iji ọgwụ mgbochi oxidant H/DPPD dị ka ihe na-egbochi oxidant n'ime ihe siri ike iji melite nchekwa nke ngwaahịa ahụ. Ejirila ya maka styrene-butadiene, acrylonitrile-butadiene, butadiene, butyl, hydroxyl, na polyisoprene roba iji nwee arụmọrụ dị ka ezigbo ndụ flex na ọchịchọ maka ime ka modulus tensile dịkwuo mma, na-eme ka ọrụ nchebe sie ike ruo na hot-oxygen, ozone na ụfọdụ ọla ndị na-emerụ ahụ dị ka ọla kọpa, manganese na-enweghị mmetụta na vulcanization nke roba ndị ahụ. Ọ nwere ike idozi nsogbu ịka nká dị na ngwaahịa roba agba miri emi ebe a na-eji antioxidant H yana antioxidant D. Ọzọkwa, enwere ike iji ya dị ka ihe na-eme ka oxygen sie ike maka ndị na-emepụta plastik dịka polyethylene, polypropylene, polyamide, na polyformaldehyde iji melite arụmọrụ ha na-eguzogide ihu igwe.
Ojiji: 1) A na-eji ọgwụ mgbochi oxidant H/DPPD (N,N'-Diphenyl-p-phenylenediamine) eme ihe dị ka ihe na-egbochi oxidant na ihe na-eme ka ọ kwụsie ike maka rọba, mmanụ mmanụ na ihe ndị na-edozi ahụ. A na-ejikwa ya dị ka ihe na-egbochi polymerization na ihe na-egbochi ire ere ọla kọpa. Ọ bụ ihe dị n'etiti kemịkalụ iji mee agba, ọgwụ, plastik, na ihe mgbakwunye ncha.
2) A na-ejikwa H/DPPD nke na-egbochi oxidation eme ihe n'imepụta polyolefins na-enweghị agba yana ihe nkiri PVC na PVB.
3) A na-ejikarị H/DPPD nke na-egbochi oxidation eme ihe n'ọtụtụ ihe ndị e ji eke na nke e ji aka mee na roba.
Nkwakọba:Akpa e ji akpa plastik kpuchie akpa ahụ, nke dị kilogram iri abụọ n'otu akpa.
Nchekwa:A na-echekwa ya n'ebe dị jụụ ma nwee ikuku. Ndụ nchekwa ya bụ ọnwa iri na abụọ mgbe ụbọchị nrụpụta gasịrị. Ọ ka dị ma ọ bụrụ na a nwalee ya ọzọ mgbe ụbọchị njedebe gasịrị.
Ntuziaka nchekwa:Nsí. A ga-eji uwe aka rọba, ihe na-eku ume na ihe nchebe anya mgbe a na-awa ahụ ma ọ bụrụ na akpụkpọ ahụ metụ ya aka, ma ọ bụ na anya ya metụ ya aka.
Njem:Zere mmiri ozuzo, ikpughe, na oke okpomọkụ.
