Tiyeni tilandire Dicyclopentadiene kuti alankhule za banja lawo.
Dicyclopentadiene(DCPD)'s Self-introduction
Chaka chabwino chatsopano, dzina langa ndine Dicyclopentadiene, dzina langa lodziwika ndi DCPD.Ndimatchedwanso Dicyclopentadiene dimer.Ndine wamadzi owoneka bwino wopanda mtundu komanso wosavuta kuwunikira, wokhala ndi fungo la camphor. Aliyense m'banja la DCPD ali ndi chikhalidwe chofanana, ndipo ndicho ntchito mu chemistry.Kodi mukudziwa chifukwa chake?
Izi ndichifukwa choti molekyulu yathu imakhala ndi zomangira ziwiri zopanda unsaturated.Chifukwa cha izi, ndife otakataka komanso okonda mitundu yonse yamachitidwe a polymerization.Kenako zotumphukira zosiyanasiyana za Dicyclopentadiene (DCPD) zidawonekera.
M'malo mwa banja langa la Dicyclopentadiene (DCPD), ndikufunirani nonse Chaka Chatsopano chabwino.
Mbiri ndi Kubadwa kwa Dicyclopentadiene(DCPD).
Tinapezedwa ngati C10H12 hydrocarbon pakati pa zinthu za pyrolysis za phenol ndi Henry Roscoe, koma adangoganiza molondola kuti ife (DCPD) tinali dimer ya C5H6 hydrocarbon m'malo mozindikira kapangidwe kathu.Pambuyo pa zaka zambiri, kapangidwe ka dicyclopentadiene (DCPD) yathu idaganiziridwa kuti ili ndi mphete ya cyclobutane monga kuphatikizika pakati pa magulu awiriwa ndipo idapangidwa mu 1931 kudzera muzoyeserera za Alder ndi mnzake.
Tidachokera ku phula la malasha koyambirira pomwe achibale athu anali ochepa kwambiri kuposa pano.Ndi chitukuko cha makampani amafuta, ambiri mwa mamembala a m'banja la DCPD obadwa kuchokera ku kagawo kakang'ono ka C5, chopangidwa ndi mafuta opangira mafuta ku ethylene.Pochita izi, zopangidwa ndi zinthu zimakhala zambiri komanso zovuta, pakati pawo, isoprene (IP), cyclopentadiene (CPD) ndi m-pentadiene (PD) onse ali ndi mtengo wogwiritsa ntchito kwambiri komanso wokhutira, zomwe zimakhala pafupifupi 50% ya C5.
Dicyclopentadiene (DCPD) imapangidwa ndi dimerization ya cyclopentadiene(CPD) ndi Diels-Alder reaction mu solution.Gawo loyamba ndikutentha kumagwiritsidwa ntchito popolymerize cyclopentadiene(CPD) mu dicyclopentadiene(DCPD), dicyclopentadiene(DCPD) imasiyanitsidwa ndi zigawo zina zowala (kuwira mfundo <45°C) ndi distillation, ndiyeno zina zofunika dienes, monocyclopentadiene amalekanitsidwa ndi zosungunulira m'zigawo.Njirayi imapezerapo mwayi pamikhalidwe yomwe cyclopentadiene(CPD) ndiyosavuta kuyimitsa kuposa magawo ena a C5.Ndiyeno dicyclopentadiene(DCPD) imasiyanitsidwa ndi tizigawo ta C5 ndi distillation chifukwa malo athu otentha ndi apamwamba kwambiri kuposa ma C5 hydrocarbons ena.
Dicyclopentadiene (DCPD)'s Employment Directions
Ife(dicyclopentadiene/DCPD) timagwiritsa ntchito zida zopangira organic ndi zitsulo za polima.Sabata yatha, ndangopereka maphunziro owongolera ntchito kwa omaliza maphunziro omwe angayambe ntchito.Ana a m'banja la DCPD ali ndi zosankha zambiri za ntchito.Ambiri aiwo azigwira ntchito muzamankhwala, mankhwala ophera tizilombo, ma resin opangira, zonunkhira, mphira wopangira ndi zina.Akhoza kusinthidwa kukhala adamantane, 2-Chloro-5-chloromethylpyridine, metallocene, glutaraldehyde, carbamate, epoxy resin kuchiritsa wothandizira, flame retardant, dicyclopentadiene chloride (tizilombo), etc. Kusankha kumeneku kudzasintha maonekedwe awo ndi khalidwe lawo.
Anthu adapeza kuti utomoni wosinthidwa wa hydrocarbon wachulukitsa reactivity mu copolymerizations ndi mafuta owumitsa, ndikupanga utomoni wa utoto wokhala ndi mawonekedwe owuma bwino, gloss, ndi kuuma.kotero a DCPD ali ndi chisankho china.Atha kujowina kampani yosinthidwa ya hydrocarbon resins.Akamagwira ntchito imeneyi, adzagwira ntchito yaikulu pa inki, zomatira ndi utoto.
Tsogolo la Dicyclopentadiene(DCPD)
Ndife banja lomwe silinganyalanyazidwe pokhala ndi phindu lathu lachuma komanso chiyembekezo chachikulu cha chitukuko.Anthu padziko lonse lapansi amapanga kafukufuku wambiri pa DCPD ndikulemba zolemba.Mkhalidwe wathu wa ntchito ukuyenda bwino ndi kutentha, ndipo ndife osasiyanitsidwa ndi moyo waumunthu.
