Tam sim no, txawv teb chaws txoj kev kos xim xim yog dej-raws li thiab tsim sai heev. Ntau tshaj 90% ntawm txoj kev kos duab xim hauv cov teb chaws tsim kho xws li Tebchaws Meskas, Lub Tebchaws Yelemees, Spain, Sweden, thiab Finland siv cov khoom siv dej. Vim thaum pib ntawm txoj kev txawv teb chaws txoj kev npav txheej thiab kev loj hlob sai ntawm kev siv tshuab, nanometer txoj kev npav txheej txheej, ob-txhim kho txoj kev npav txheej, xim-coated txoj kev npav txheej, thiab lwm yam tau tshwm sim.
Rosin glycerol resin yog cov khoom ntawm esterification ntawm rosin nrog glycerol. Nws yog cov pob tshab tsis tu ncua tom qab kho lub tshuab nqus tsev.
Ntu Ib: Peb Cov Khoom Siv Siab Siab Calcium Hlau Ntau Lawm Feem Ntau Txhua Xyoo Tso Tawm yog kwv yees li 1500 tuj hauv ib xyoos thiab qhov purity tuaj yeem ncav cuag 99.99%
Ethylene cracking C5 feem atmospheric siab rectification intercepts 45-75â ¢ isoprene enriched tivthaiv raws li raw khoom A; ethylene cracking C5 feem atmospheric siab rectification intercepts 25-45â º ̓ isoprene enriched tivthaiv raws li raw khoom B; Ethylene cracking C9 feem yog lub tshuab nqus tsev rectified nyob rau hauv 0.08ï½¢ 0.095MPa, Petroleum Resin thiab cov feem nrog boiling point ntawm 140ï½ ោង 180â ¢ 180â ¢ yog coj los ua cov khoom siv raw C. Cov khoom siv raw li A, B thiab C yog npaj raws li qhov loj piv ntawm 1: 1.5ï½ 3.0: 1.5ï½ 3.0 C5 / C9 roj av resin polymerization raw khoom D;
C5 roj av resin hloov mus rau hauv C5 hydrogenated petroleum resin los ntawm hydrogenation nyob rau hauv palladium bimetallic catalyst. Cov catalyst muaj alumina-titania composite carrier thiab hlau palladium thiab hlau molybdenum los yog hlau tungsten txhawb nqa ntawm cov cab kuj; Petroleum Resin Cov ntsiab lus yog 0.2-0.4% raws li qhov hnyav ntawm catalyst;
Nrog rau txoj kev loj hlob sai ntawm lub teb chaws kev lag luam, Roj av Resin tshwj xeeb tshaj yog kev loj hlob sai ntawm peb lub thoob roj, xws li Sinopec, ethylene peev tau maj mam nce, Roj av Resin thiab ntau thiab ntau C9 yog tawg. Yuav ua li cas siv ib feem ntawm cov peev txheej los tsim cov khoom lag luam hauv qab no ua rau tib neeg nyiam.
