Oyinza otya okulongoosa obuziyiza bw’ebbugumu mu kapiira?
Okuziyiza okukaddiwa kw’empewo okw’ebbugumu oba okukaddiwa kw’ebbugumu kweyongera okuba okw’omugaso naddala mu kukola mmotoka ng’ebitundu bya kapiira bisinga kukozesebwa mu bifo ebibikkiddwako ebbugumu eriri waggulu. Abakola mmotoka bawulira nga bongera okunyigirizibwa okwewaayo mu bulamu bw’obuweereza obw’ekiseera ekiwanvu olw’ebitundu byabwe ebya kapiira. Ebintu eby’okukaddiwa mu bbugumu eritali mu mukka n’eby’okukaddiwa kw’ebbugumu n’empewo bya njawulo. Omupiira gulina obuziyiza obulungi ebbugumu, naye guyinza okuba nga tegunnagumira kulumbibwa mukka gwa oxygen.
Weetegereze: Enkola zino ez’okugezesa eza bulijjo ziyinza obutakola ku buli musango ogw’enjawulo. Ekimu kyonna ku bintu ebikyukakyuka ebiyinza okulongoosa okuziyiza kw’empewo oba okuziyiza okukaddiwa kw’ebbugumu kijja kukosa ddala eby’obugagga ebirala, oba mu bulungi oba mu bubi.
1. Perfluoroelastomer .
Singa ekintu kya kapiira kyetaagisa okuba n’obuziyiza obulungi obw’ebbugumu, wandibadde olondawo akapiira akayitibwa perfluorinated rubber. Kigambibwa nti ebbugumu ly’okukozesa perfluoroelastomer liri ku 316°C.
2、 Omupiira gwa fluorine .
Fluorine Rubber FKM erina obuziyiza obulungi obw’ebbugumu, era esobola okukozesebwa ku bbugumu erituuka ku 260°C. Okusobola okwongera okunyweza obuziyiza bwa fluorine obw’ebbugumu eringi, olina okulonda ekikkiriza asidi omutuufu (acid absorbent), gamba nga low activity magnesium oxide, high activity magnesium oxide, calcium oxide, calcium hydroxide, zinc oxide, etc. Fluoroelastomer eziyiza okusannyalala kw’empewo nayo nnungi nnyo, era ebbugumu eriyinza okuba nga 2000 resistant peranceing performance is very good, era the use the as as as as as as 200 resistant resistant performance is as as as as as as as as 200 resistant resistant performance, is very good, and the the as as as as as as as 200) Nga olondawo bisphenol AF ng’enkola ya Vulcanization, okuziyiza okukaddiwa kw’ebbugumu kwa kapiira kujja kuba kusinga. Ekozesebwa mu mbeera ya woyiro wa yingini enkambwe, okuziyiza okukaddiwa kw’ebbugumu okwa ternary fluoroelastomer ekoleddwa mu vinylidene fluoride, tetrafluoroethylene ne propylene asinga general fluoroelastomer. Kino kiva ku kukyusa hexafluoropropylene nga propylene mu nkola ya polymerization.
3、 HNBR .
Diguli ya haidrojeni gyekoma okuba waggulu, n’obuziyiza bw’ebbugumu bwa HNBR gye bukoma okuba obulungi, kubanga kumpi tewali kiyungo kya mirundi ebiri ekitali kijjudde ku lujegere olukulu ekitali kinywevu. HNBR ezimu zikyayinza okufuulibwa vulcanized ne sulfur kubanga zikyalina unsaturated double bonds. Naye singa vulcanized ne peroxide, obuziyiza ebbugumu obw’ekirungo bujja kulongoosebwa. Ku HNBR rubber, TOTM esobola okuwa obuziyiza bw’ebbugumu okusinga DOP olw’okukyukakyuka okutono n’obuzito bwa molekyu obw’ebiziyiza bino ebya trioctyl.
4. Neoprene .
W-type neoprene erina obuziyiza obulungi obw’ebbugumu okusinga neoprene ow’ekika kya G. Diphenylamine octanoate ye antioxidant esinga obulungi ku neoprene, ekiyinza obulungi okulongoosa obuziyiza ebbugumu.
5、 EPDM .
EPDM ejja kuba ekyalina obuzibu obulungi obw’ebbugumu ku 125°C oluvannyuma lw’okutuuka obulungi. Okukozesa peroxide vulcanized EPDM, kiyinza okufuula omupiira okuba n’ebbugumu erisinga obulungi.
6、 low viscosity omukka ogw'omutendera enkola EPDM .
Ebirungo bya ethylene ebingi ne ultra-low viscosity vapor phase EPDM, bisobola okujjula omuwendo omunene ogw’ebijjuza, olw’ebirungo bya ethylene ebingi, okulongoosa tekyetaagisa kugatta kukola ku kukaddiwa kw’empewo okugumira ebbugumu okutali kwa bulungi era resin, kukyayinza okufuula omupiira n’ebintu ebirungi eby’okukola, kale okuziyiza ebbugumu okwennyini okwa kapiira ne kulongoosebwa.
7、 Weewale okukozesa resin ya styrene enkulu .
Weewale okuteeka resin ya styrene enkulu mu kapiira akakozesebwa mu bbugumu erya waggulu.
8、 Pawuda wa talcum .
Mu EPDM hose rubber, zzaawo ebitundu 40% ku kaboni omuddugavu osseeko butto wa talcum, ekiyinza okulongoosa obuziyiza bw’ebbugumu eri okukaddiwa kwa kapiira. Ebika ebimu ebya talcum powder birina ebirungi eby’enjawulo okusinga ebbumba erijjanjabiddwa oba eritajjanjabiddwa mu nsonga eno.
9、 Ekirungo ekiziyiza obuzito (high viscosity)
Mu buveera, obuveera bwa viscosity obw’amaanyi busobola okuwa ebbugumu erikaddiwa obulungi okusinga obuveera obutono obw’obuzito bwa viscosity. Olw’okuba ekiveera ekizitowa ennyo kitera okuba n’obuzito bwa molekyu obw’amaanyi, si kyangu kukyusakyusa, bwe kityo okutebenkera okulungi n’okuziyiza ebbugumu okulungi.
10、Amafuta g'ensigo z'okufumba ku neoprene .
Okusobola okukola neoprene okuba n’obugumu obulungi, woyiro wa canola yeetaagibwa kubanga alina viscosity entono, ekifuula omupiira okuba ne hysteresis entono n’okukyukakyuka okutono, ekiyinza okufuula omupiira okuba n’obuziyiza obulungi okukaddiwa.
11、Enkola ya EV/semi-effective Sev Vulcanization .
In the effective or semi-effective vulcanization system, the ratio of accelerator and sulfur is high, that is, 'high promotion and low sulfur' system, with 'sulfur to the body' instead of single sulfur, in this vulcanization system, the proportion of single sulfur bond and double sulfur bond in the vulcanized rubber is higher, because of its stability In this vulcanization system, the ratio of single sulfur bond Era ekiyungo kya sulphur eky’emirundi ebiri kiri waggulu okusinga eky’ekiyungo kya sulfur multi-sulfur, n’olwekyo, obutebenkevu bw’obuziyiza bw’ebbugumu bwa kapiira bulongooseddwa era obuziyiza okukaddiwa kw’ebbugumu bulongoosebwa.
12、zinc oxide .
Vulcanization / sub-sulfuramide vulcanization system of the rubber, ejjude zinc oxide omungi, esobola okuwa omupiira ebbugumu okukaddiwa obulungi n’okuziyiza obulungi oluvannyuma lwa sulfur.
13、Peroxide Vulcanized EPDM Omupiira .
Mu kirungo kya EPDM ekifuuse perokisayidi, ZMTI elonda nga antioxidant, ekiyinza okuwa ekirungo modulus esingako n’obuziyiza bw’okukaddiwa kw’ebbugumu.
