Okulongoosa mu buziyiza bwa ozone obw’amaanyi obwa chloroprene rubber .

Mu myaka egiyise, eby’obugagga eby’amaanyi ebya kapiira naddala obuziyiza bwa ozone obw’amaanyi bweyongera okusaba. Okulonda obuziyiza bwa ozone obulungi ennyo obwa kapiira n’ekirungo ekiziyiza obuwuka obuleeta obulwadde, oba kapiira era nga kitundu ku ngeri y’okugonjoolamu ebizibu bino. Chloroprene rubber (CR) is made of chloroprene as a monomer emulsion polymerization of polymers, since the twentieth century, 30 years by the United States DuPont developed successfully, first used in the shoe industry, because it is inexpensive, strong adhesive force, adhesive time is long, the activation temperature is low, not only to adapt to automated large-scale production, but also suitable for manual work, and quickly gained wide okusaba. Chloroprene rubber erina okuziyiza okulungi ennyo eri oxygen ne ozone, non-flammable, self-extinguishing oluvannyuma lw’omuliro, okuziyiza amafuta, okuziyiza solvent, asidi ne alkali okuziyiza n’okuziyiza empewo okutambula obulungi. Omulimu oguliwo kati kwe kukozesa chloroprene rubber nga omupiira omukulu, era okusinziira ku kukyusibwa kwayo, okusobola okufuna obuziyiza bwa ozone obukyukakyuka obulungi.

I. Ebivuddemu n’Okukubaganya ebirowoozo .

1. Okulongoosa obuziyiza bwa ozone obukyukakyuka obwa chloroprene rubber nga bikozesebwa antioxidants .

Oluvannyuma lw’okugattako RD eziyiza obuwuka obuleeta obulwadde, obuziyiza bw’okukyukakyuka kw’okunyigirizibwa n’okuziyiza ozone ebya kapiira akayitibwa vulcanized rubber byalongoosebwa okutuuka ku diguli ez’enjawulo, ate eby’omubiri ebirala tebyakyuka nnyo. Bwe ddoozi ya antioxidant RD bwe yayongezebwa okuva ku bitundu 0 okutuuka ku 2, obudde bwa ozone obw’okukutuka kwa Cr vulcanized rubber bwayongezebwa okuva ku 120h okutuuka ku 408h, kale kiyinza okulabibwa nti quinoline antioxidant RD esobola okulongoosa ennyo amaanyi ga dynamic ozone okukaddiwa kwa CR vulcanized rubber, naye tekosa cr physical rubbers physical physical physical rubber.

2.EPDM / Cr era olongoose obuziyiza bwa ozone obukyukakyuka obwa chloroprene rubber .

Chloroprene rubber Okukola cable protective sheath rubber formulation, tekwata ku aniline antioxidants ne quinoline antioxidants, okulongoosa dynamic ozone resistance yaayo esobola okukozesebwa nga ekwatagana ne EPDM ne chloroprene rubber. Okuva ku data y’okugezesa eyinza okulabibwa oluvannyuma lw’okugattako EPDM, obuziyiza bwa ozone obukyukakyuka obwa vulcanized rubber okusinga ensengekera eyasooka okulongoosa omulimu kumpi emirundi 10, nga kwotadde n’okweyongera okutono mu kunyigiriza okukyukakyuka, eby’obutonde ebirala okusinga bisobola okulabirira ku ddaala eryasooka. Chloroprene Rubber ne EPDM rubber, zisobola okulongoosa ennyo obuziyiza bwa ozone obw’amaanyi obwa vulcanized rubber.

II. Ebimalirizibwa .

1. Ku hoosi ezimu eza chloroprene rubber, okusobola okulongoosa obuziyiza bwayo obw’okukaddiwa kwa ozone obukyukakyuka awatali kukosa nkola yaayo ey’omubiri okutwalira awamu, osobola okukozesa antioxidants ezesigamiziddwa ku aniline n’ebirungo ebiziyiza obuwuka obuleeta obulwadde bwa quinoline obutasukka bitundu bibiri ebya RD era osobola okulongoosa obulungi obuziyiza bwa ozone obukyukakyuka obwa kapiira akayitibwa vulcanized rubber, emirundi egisukka mu esatu.

. Ebigezo bikakasizza nti, awatali kukosa nnyo nkola ya mubiri enzijuvu ey’ensengekera eyasooka wansi w’ensonga y’ekitundu ekituufu ekya ethylene propylene diene monomer ) (EPDM) ne chloroprene rubber (Crc) era zisobola okulongoosa ennyo obuziyiza bwa ozone obw’amaanyi obw’okukaddiwa kwa vulcanized rubber.
