Cov khoom
Dawb los yog lub teeb grey hmoov (granule). Qhov ntom ntom 1.29. Soluble hauv chloroform, acetone, benzene, CS2; ib nrab soluble hauv cawv, diethyl ethyl ether, CCL4, insoluble hauv dej, roj av thiab alkali nrog qis concentration. Ua rhiab rau ntawm daim tawv nqaij thiab peogaster.
Daim ntawv thov
Nws tuaj yeem siv los ua ib qho accelerator, ua tus accelerator thib ob lossis ua tus neeg muab cov sulfur nyob rau hauv feem ntau cov sulfur- kho elastomers. Scorchy thiab muab ceev kho tus nqi. Ua tau zoo heev vulcanisation toj siab nrog zoo tshav kub laus thiab compression teeb kuj. Nyob rau hauv sulfurless thiab EV kho tshuab. Kev tuav xim zoo yog tau txais tsis yog -vulcanisation dub. Ib qho tseem ceeb thib ob accelerator rau EPDM. Tej zaum yuav siv tau los ua ib qho retarder nyob rau hauv vulcanisation ntawm polychloroprene roj hmab nrog Accelerator ETU thiab kuj yuav siv tau raws li bactericide thiab tshuaj tua kab.

Cia
Khaws lub thawv kaw kom nruj rau hauv qhov chaw txias, zoo - qhov cua. Awaiting raug cov khoom ntim rau lub hnub ncaj qha. Qhov kev pom zoo siab tshaj plaws cia lub neej yog 2 xyoos thaum khaws cia hauv ib txwm muaj.
Thawj cov dej khib nyiab ntawm cov roj hmab ntuj muaj ntau cov tetramethylcyclodisulfide (TMTD). Kev tso tawm ntawm cov roj hmab ntxuav cov dej khib nyiab yog ib qho tseem ceeb ntawm TMTD cov pa phem nyob rau hauv cov av ib puag ncig ntawm cov chaw tsim khoom siv roj hmab. Ib qho degradation strain Enterobacter bugandensis raug cais tawm ntawm cov av tsis huv, uas tuaj yeem ua rau TMTD zoo.
