1. Natural Roj Hmab: Cov roj hmab ntuj yog muab rho tawm los ntawm cov kua txiv hmab txiv ntoo. Nws yog mos thiab muaj zoo elasticity. Vim nws cov vulcanization qeeb qeeb, ketone-amine accelerators feem ntau yog siv los ua kom cov txheej txheem vulcanization. Nyob rau tib lub sijhawm, cov cua sov ua haujlwm thiab kev laus ua haujlwm ntawm cov roj hmab ntuj tuaj yeem txhim kho nrog cov accelerators tsim nyog.
2. Butadiene Roj Hmab: Butadiene roj hmab yog ib hom roj hmab hluavtaws, dav siv hauv cov log tsheb thiab cov khau khau vim nws qhov zoo tiv thaiv thiab tsim kua muag. Thioamine accelerators feem ntau yog siv rau cov roj hmab butadiene thaum lub sij hawm vulcanization vim hais tias lawv muaj ib tug ruaj khov accelerating nyhuv ntawm kub dua.
3. Isoprene Roj Hmab: Isoprene roj hmab yog cov roj hmab hluavtaws uas muaj lub cev zoo heev, feem ntau yog siv los tsim cov raj sab hauv thiab cov ntsaws ruaj ruaj. Rau isoprene roj hmab, siv cov organic peroxides li accelerators tuaj yeem txhim kho nws cov thermal stability thiab kev laus tiv thaiv, thaum tseem ua kom cov uniformity thaum lub sij hawm vulcanization txheej txheem.
4. Styrene-butadiene roj hmab (SBR): SBR yog siv dav hauv kev lag luam tsheb thiab lub teeb. Nws cov huab cua tsis kam thiab kev puas tsuaj ua rau nws yog ib qho tseem ceeb hauv cov khau roj hmab thiab cov hlua. Los ntawm kev xaiv cov thioamine accelerators tsim nyog, lub cev lub cev ntawm SBR tuaj yeem txhim kho tau zoo.
5. Reclaimed rubber: Reclaimed rubber yog ib yam khoom tau los ntawm kev ua thiab rov ua dua cov roj hmab pov tseg. Nws muaj qhov zoo ntawm tus nqi qis thiab ua kev lag luam thiab ib puag ncig tus phooj ywg. Ntxiv cov roj hmab accelerators thaum lub sij hawm ua cov roj hmab reclaimed tsis tau tsuas yog txhim kho vulcanization efficiency tab sis kuj txhim kho kev ua tau zoo ntawm cov khoom kawg.
