Chifukwa cha Mooney viscometer na vulcanizer, nchamachitiko kuyezga vyose viŵiri vyakusakanizga na kusazgikana kwa labala nyengo yiliyose, mwakuti vileke kuwotcha vinthu vya labala .Mu kupanga kwa mafakitare gha labala ghakusakanizgika, palije kukhumbikwa kwa kuŵikapo mtima kwakukwana, kweni kuti mtundu wa labala ugwiriskike nchito na nthowa yakuŵikapo mtima {nthengwa {{{ {2}Pano nthowa yakuyileskera ku moto {{{{{;}}

Chakwamba, kuchepeskako unandi wa vulcanization accelerator, kweni ichi chizamupangiska kuti vinthu vyakuwoneka vya vinthu vya labala vichepe, nchakuzirwa chomene kupulikiska ichi, vulcanization accelerator iyo yikugwiriskirika nchito pera yikusoŵa, chomenechomene nkhugwiliskira ntchito viŵiri, vitatu vya accelerator na nthowa .panji pali suzgo na kukolerana, nchakusuzga kuleskera labala kuti uleke kuwotcha. Kumoza, nkhongono yikuru likugwiriskirika nchito pa labala wakumanyikwa chomene ni piritsi panji sulfonylamine chakukhozga . Chinthu chikuru icho chikukhozgera DM ni chinthu chakukhozga chomene .Chithandizo cha promoter M chili na kuchuluka kwapachanya, nangauli sulfonphthalein amine accelerator yili na scorchability, kweni chifukwa cha kuyamba kwakuchedwa kwa vulcanization, yikwenera kusankhika mwakuyana na ivyo vikukhumbikwa pa kugwiriskira ncito labala . Mususcle. kukhozgera kwakovwira.Mu nyengo ya kutentha kwapachanya pakati pa chilimwe, kukhozgera kwakovwira kuti kuchepeske unandi wa kugwiriskira ntchito, ndipo wakukhozgera mulara wali na mwaŵi wakuti waleke kuchepeska mlingo wake wa mlingo (6}}

Labala wakupangikaso wa 10-20 misa wakusazgikira mu labala wose, ndipo vinthu vya raba vikupangika na kusakanizga, ivyo vili na ntchito ya kuleskera kuwotcha .Kusazgirapo, kupanga kwakusazgapo kukwenera kughanaghanirika mu kapangidwe ka vinthu vyakusakanizga, ndipo kusintha kunyake kwakukhumbikwa kukwenera kupangika pa fundo ya kafukufuku pa katundu wakuwoneka wa coke na vulcanizates{{}}

Mu kukolerana na silica gel vinthu, kuti ŵasazgireko vyakurya vya vyakurya vya glycol, polyethylene glycol, polyethylene glycol, amine amine accelerator SL.Kweni, kusazgirapo kwa vinandi vya pachanya kuzamupangiskaso kuti munthu waŵe na coking, ntheura vikwenera kumanyikwa.Mlingo wakuzomerezgeka ukwenera kuŵa (wakupimika na mtundu wa carbon wakufipa) glycol glycol na polyethylene glycol (mzimu wa molecular 400) 60%, amine amine wakukhozgera SL 2.5%.

Mu chigaŵa cha kukolerana, nangauli nga umo vyayowoyekera pacanya apa, vikadumbiskana vinandi, kweni usange vingakwaniska yayi kuphika, vingasazgirako wovwiri wakulimbana na kuphika (vyakuchedweska vulcanization) . Vulcanization retarders ni vyakupangika vya phthalic acid na benzoic acid, vyakupangika na nitroso na phthalamines {2}Nitroso - diphenylamine yingagwiliskirika nchito yayi mu ungweru - mtundu wa labala wa mitundu chifukwa cha kufipiskika kwake .

Munthu uyo wakukanizga coke wakuchepeskaso vulcanization uku wakuchedweska vulcanization chifukwa wakuchepeska crosslinking, ntheura mungachigwiliskira ntchito yayi mu unandi .Mu ivyo ŵalembi ŵakukumana navyo, mlingo ukwenera yayi kuluska 0.4%.} Usange ukukhumbikwira kuluska 0.4%, unandi wa vulcanization accelerator ukwenera kuchepeskeka dankha.Mungagwiriskira ntchito yayi wakukhozgera chomene, wakulimbana na cooking nthowa.
