Tsaug Mooney viscometer thiab vulcanizer, nws yog ua tau los ntsuas ob qho tib si tshiab cov khoom sib xyaw thiab tshiab xim roj hmab txhua lub sij hawm, li ntawd kom tsis txhob kub ntawm cov roj hmab cov ntaub ntawv.Qhov qhov ntau lawm ntawm cov khoom siv roj hmab sib xyaw roj hmab, tsis tas siv ib qho kev txiav txim siab, tsuas yog rau cov lus qhia kom paub meej rau cov roj hmab siv los ntawm ib txoj kev txiav txim siab.Ntawm no yog yuav ua li cas tiv thaiv nws los ntawm hlawv.

Ua ntej tshaj plaws, los txo tus nqi ntawm qhov siv accelerator, tab sis qhov no yuav ua rau lub zog ntawm cov khoom siv roj hmab poob qis, nws tseem ceeb heev kom nkag siab txog qhov no, tus nplaig nplawm siv ib leeg tsis tshua siv, feem ntau yog siv ob, peb lub zog thiab txoj kev.Thaum kawg muaj ib qho teeb meem nrog kev ua kom sib haum, nws tseem tsis tau kom tsis txhob rubber hlawv. Feem ntau, lub ntsiab stimulant siv rau roj hmab feem ntau yog cov ntsiav tshuaj los yog sulfoniline stimulant.Qhov ntsiab promoter DM yog ib tug universal promoter.Qhov txhawb M muaj lub siab scorchability, Txawm hais tias cov theem sulfonphthalein amine accelerator muaj cov scorchability, tab sis vim pib qeeb ceev ntawm vulcanization, nws yuav tsum tau xaiv raws li qhov yuav tsum tau siv cov roj hmab.Muscle thiab thiuram yog cov kws pab txhawb nqa.Nyob rau hauv lub caij kub siab hauv midsummer, pab txhawb nqa kom txo tau qhov siv, thiab cov neeg txhawb loj yog kom deb li deb ua tsis tau kom txo nws cov tshuaj.

Cov roj hmab siv dua 10-20 pawg ntxiv rau hauv cov roj hmab, thiab cov khoom siv roj hmab yog ua los ntawm blending, uas muaj cov kev tiv thaiv kev kub nyhiab. Ntxiv rau, cov tshuaj ntxiv rau yuav tsum muab xam rau hauv cov khoom tsim, thiab qee qhov tsim nyog Kev hloov kho yuav tsum tau ua raws li kev tshawb fawb ntawm lub cev nqaij tawv thiab cov ntxhuav.

Kev sib xyaw nrog silica gel khoom, ntxiv diethylene glycol, polyethylene glycol, organic amine accelerator SL.However, qhov sib ntxiv ntawm ntau ntau ntawm cov saum toj no yuav ua rau coking, yog li nws yuav tsum tau muab sau tseg.Qhov kev noj tshuaj yuav tsum yog (piv nrog dawb carbon dub) diethylene glycol thiab polyethylene glycol (molecular luj 400) 60%, organic amine promoter SL 2.5%.

Hauv kev ua kom sib haum, tab sis raws li tau hais los saum no, tau sib tham ntau, tab sis yog tseem tsis tuaj yeem tiv thaiv coking, ntxiv rau tus neeg sawv cev coking (tus sawv cev ntawm tus neeg laus dua) .Vulcanization retarders yog cov organic compounds ntawm anhydrous phthalic acid thiab benzoic acid, nitroso compounds thiab phthalamines.Nitroso - diphenylamine tsis tuaj yeem raug siv nyob rau hauv lub teeb - xim roj hmab cov khoom vim nws cov pa phem.

Tus coke inhibitor kuj ua rau kev quab yuam ua rau lub sijhawm hloov qis dua vim tias nws txo qhov kev sib tw, yog li tsis siv nws ua qhov loj. Nyob hauv kev sau ntawv, qhov ntau npaum li cas yuav tsum tsis pub tshaj 0.4% .Yog hais tias nws yuav tsum tau ntau tshaj 0.4%, tus nqi ntawm accelerator vulcanization yuav tsum tau txo thawj zaug.Tsis txhob siv cov neeg txhawb zog siab, tus cwj pwm coj cwj pwm ncaj qha.
