I. Omupiira ogw’obutonde .

Okunyiga amazzi: Okunyiga amazzi mu kapiira ak’obutonde kwawukana n’ekisengejjo ky’okuzimba (coagulation concentration) ekya latex, ekika ky’ekikuuma n’eky’okunywa, puleesa y’okunaaba n’embeera y’okukala mu nkola y’okukola emipiira, kale waliwo enjawulo ezeeyolese mu kunyiga amazzi mu bika by’ebintu eby’enjawulo.

II. Omupiira gwa Styrene butadiene .

Okunyiga amazzi: Okufaananako ne kapiira ak’obutonde.

iii. Butadiene Omupiira .

Okunyiga amazzi amatono: Okunyiga amazzi mu kapiira ka butadiene kuli wansi okusinga ku kapiira ka butadiene aka styrene ne kapiira ak’obutonde, akayinza okufuula akapiira ka butadiene akakozesebwa okuziyiza waya z’amasannyalaze n’ebintu ebirala eby’omu kapiira ebyetaaga okuziyiza amazzi.

iv. Butyl Omupiira .

Butyl rubber erina amazzi matono nnyo, amazzi agaziyiza obulungi mu bbugumu okutwalira awamu, ate omuwendo gw’okunyiga amazzi ku bbugumu erya bulijjo guba wansi emirundi 10-15 okusinga emipiira emirala. Omutindo guno omulungi ennyo ogwa butyl rubber kikulu nnyo mu kuyamba mu kuziyiza amasannyalaze. Butyl rubber enywezeddwa ne carbon black ne vulcanized ne resin esobola okufuna low water absorption performance wansi w’ebbugumu eringi n’embeera z’okubikkula ez’ekiseera ekiwanvu. Okusobola okusobozesa omupiira gwa butyl okubeera mu mazzi oba ebbugumu eringi okumala ebbanga eddene, bino wammanga birina okukolebwa mu nkola:

1, ekijjuza kirina okuba nga si kya hayinja era nga kya meta-electrolytic.

2, ebintu ebitabulwa mu mazzi eby’enkola ya Vulcanization birina okuba nga bitono nga bwe kisoboka .

.

V. Omupiira gwa ethylene propylene .

Amazzi agookya n’obuziyiza bw’omukka gw’amazzi. Ethylene propylene rubber erina obuziyiza bw’omukka obulungi, n’okusinga obuziyiza ebbugumu bwayo. Obuziyiza bwayo obw’omukka ogw’amaanyi (high-pressure steam resistance) businga butyl rubber ne general rubber. Ethylene propylene rubber nayo erina okuziyiza okulungi eri amazzi agookya, naye ekwatagana nnyo n’enkola ya Vulcanization ekozesebwa. Okukozesa enkola ya peroxide n’enkola ennungi ey’okufuula ethylene propylene rubber vulcanization rubber peroxide performance nnyo okusinga sulphur vulcanization ya ethylene propylene rubber oba butyl rubber, naye sulphur vulcanization of ethylene propylene rubber rubber performance is worse than the sulfur vulurization of butyyl rubber.

vi. Omupiira gwa Neoprene .

Okuziyiza amazzi kusinga kapiira akalala akakolebwa, okunywezebwa kwa ggaasi kukwata kyakubiri ku kapiira ka butyl.

Okuteekateeka kapiira akaziyiza amazzi ga neoprene, kulina okussaayo omwoyo ku nkola y’okulonda enkola ya vulcanization n’okujjuza. Enkola ya Vulcanization esinga okukozesa enkola ya lead oxide, okwewala okukozesa magnesium oxide, zinc oxide system. Lead oxide dosage Mu bitundu 20 oba wansi, waliwo omulimu mu kulongoosa obuziyiza bw’amazzi, naye omuwendo guyitiridde naye nga tegukola. Nga okozesa lead sulfide, okulonda okusinga okunyweza kaboni omuddugavu, kaboni omuddugavu mu nkola ya slot carbon black esinga, enkola y’ekikoomi Carbon Black y’ekwata ekyokubiri. Inorganic filler esinga kukozesa calcium silicate, n’eddirirwa barium sulfate, ebbumba, n’ebirala.Ebirungo byonna ebigonza amazzi tebirina kukozesebwa. Era tesaana kukozesa sulfur vulcanization. Okutwalira awamu omulimu gw’okwokya kwa kapiira oguziyiza amazzi guba mubi, gulina okwetegereza ng’ogulongoosa.

VII. Omupiira gwa Nitrile .

Okuziyiza amazzi kulungi: Olw’okweyongera kw’ekirungo kya acrylonitrile, okuziyiza amazzi kweyongera.

VIII. Omupiira gwa silikoni .

Hydrophobicity: Amasoboza ag’okungulu ga silikoni ga wansi okusinga ebintu ebisinga ebiramu, n’olwekyo, birina okunyiga obunnyogovu obutono, okunnyika okw’ekiseera ekiwanvu mu mazzi, omuwendo gw’okunyiga amazzi gaakyo nga 1% zokka, eby’omubiri n’eby’ebyuma tebikendeera, okuziyiza kw’ekikuta kirungi.

ix. Omupiira gwa fluorine .

Omutindo ogutebenkedde ku mazzi agookya. Waliwo okuziyiza okulungi ennyo eri omukka ogw’ebbugumu eringi.

Fluorine rubber ku kifo ky’okunyweza amazzi agookya, tekoma ku kusinziira ku butonde bwa kapiira akabisi yennyini, naye era n’okusalibwawo ekintu kya kapiira nga kiriko. Ku kapiira ka fluorine, omulimu guno gusinga kusinziira ku nkola yaayo eya Vulcanization. Enkola ya peroxide vulcanization esinga amine, enkola ya bisphenol AF ekika kya vulcanization. 26 Ekika kya fluoroelastomer nga tukozesa enkola ya amine vulcanization Omutindo gwa kapiira mbi okusinga omupiira ogw’obutonde ogwa bulijjo nga ethylene propylene rubber, butyl rubber. G-type fluorine rubber Nga tukozesa peroxide vulcanization system, cross-linked bonds za vulcanized rubber okusinga amine, bisphenol AF type vulcanized rubber cross-linked bonds to hydrolysis stability esinga.

X. .

Ekimu ku binafu eby’enjawulo ebya polyurethane: obutaziyizibwa buziyiza bwa mazzi bubi naddala ku bbugumu erya waggulu katono oba okubeerawo kwa asidi ne alkali media hydrolysis mu bwangu.

XI. Chlorine Ether Omupiira .

homopolymerized chloroether rubber ne nitrile rubber zirina obuziyiza bw’amazzi obufaanagana, obuziyiza amazzi aga chloroether chloroether obuziyiza wakati wa nitrile rubber ne acrylate rubber. Ensengeka erina kinene ky’ekola ku kuziyiza amazzi, erimu okuziyiza amazzi ga kapiira ga PB3O4 kisingako, nga kirimu okuziyiza amazzi ga MGO nga kibi nnyo, okulongoosa ddiguli y’okufuuka vulcanization esobola okulongoosa okuziyiza amazzi.

XII. Omupiira gwa chlorosulfonated ogwa polyethylene .

Cross-linking chlorosulfonated polyethylene rubber ne epoxy resin oba ebitundu ebisukka mu 20 ebya lead monoxide bisobola okufuula vulcanized rubber okuba n’amazzi amalungi. Ekijjuza ekikozesebwa nga kwotadde ne calcium carbonate, ekijjuza ekya bulijjo okutonnyeza barium sulfate, ebbumba erikaluba n’ebbugumu erya thermal cracking carbon black lisinga okusaanira. Okugatta ku ekyo, okusobola okufuula akapiira akayitibwa vulcanized rubber okufuna obuziyiza amazzi amalungi, vulcanization ey’okumpi kikulu nnyo.

Ku lw’okubeera mu mazzi mu mazzi oba mu kiseera ekitono, okutwalira awamu barium oxide asangibwa nga vulcanizing agent, nga mu chlorosulfonated polyethylene rubber n’ebitundu nga 5 eby’amafuta ga silicone, olwo ne cross-linked ne magnesium oxide vulcanization rubber mu mazzi swelling rate ntono nnyo.

XIII. Acrylate Omupiira .

Olw’okuba ekibinja kya ester kyangu okufuuwa amazzi, okukola akapiira ka acrylate mu mazzi omuwendo gw’okuzimba kinene, BA type rubber mu 100 °C amazzi agabuguma oluvannyuma lw’okugejja 72h 15-25%, okugaziya volume ya 17-27%, okugumira omukka kisinga bubi kibi nnyo.
