Masamkele iDicyclopentadiene ukuba yenze intetho ngosapho lwabo.
I-Dicyclopentadiene(DCPD)'s Ukuzizisa
Unyaka omtsha owonwabileyo, igama lam ndinguDicyclopentadiene, igama lam le-DCPD.Ndikwabizwa ngokuba yiDicyclopentadiene dimer.Ndingulwelo olungenambala olucacileyo kwaye kulula ukukhazimla, kunye nevumba le-camphor.Wonke umntu kusapho lwe-DCPD unophawu oluqhelekileyo, kwaye ngumsebenzi kwikhemistri.Ngaba uyasazi isizathu?
Oku kungenxa yokuba imolekyuli yethu iqulethe iibhondi ezimbini ezingaxutywanga.Ngenxa yolu phawu, sisebenza kakhulu kwaye sityekele kuzo zonke iintlobo zokusabela kwepolymerization.Emva koko kwavela izinto ezahlukeneyo zeDicyclopentadiene (DCPD).
Egameni losapho lwam iDicyclopentadiene (DCPD), ndininqwenelela unyaka omtsha omnandi.
Imbali yeDicyclopentadiene(DCPD) kunye noKuzalwa
Sifunyenwe njenge-C10H12 hydrocarbon phakathi kweemveliso ze-pyrolysis ye-phenol ngu-Henry Roscoe, kodwa wayecinga ngokuchanekileyo ukuba thina (i-DCPD) sasiyi-dimer ye-C5H6 hydrocarbon endaweni yokuchonga isakhiwo sethu.Emva kweminyaka emininzi, ukwakhiwa kwe-dicyclopentadiene yethu (DCPD) kwakucatshangelwa ukuba ibonise indandatho ye-cyclobutane njenge-fusion phakathi kwee-subunits ezimbini kwaye ikhutshwe kwi-1931 ngemigudu ka-Alder kunye nomsebenzi osebenza naye.
Sasuka kwitela yamalahle kwasekuqaleni xa sasimbalwa kakhulu amalungu entsapho kunangoku.Ngophuhliso lweshishini leoli, uninzi lwamalungu kwintsapho ye-DCPD ezelwe kwiqhezu le-C5, imveliso ye-petroleum yokuqhekeka kwi-ethylene.Kule nkqubo, iimveliso zemveliso zininzi kwaye ziyinkimbinkimbi, phakathi kwazo, i-isoprene (IP), i-cyclopentadiene (CPD) kunye ne-m-pentadiene (PD) zonke zinexabiso eliphezulu lokusetyenziswa kunye nomxholo ophezulu, obangela malunga ne-50% ye-C5 iqhezu.
I-Dicyclopentadiene (DCPD) yenziwe yi-dimerization ye-cyclopentadiene (CPD) yi-Diels-Alder reaction in solution.Inyathelo lokuqala lokufudumeza lisetyenziselwa i-copolymerize cyclopentadiene (CPD) kwi-dicyclopentadiene (DCPD), i-dicyclopentadiene (DCPD) yahlulwe kwamanye amacandelo okukhanya (indawo yokubilisa <45 ° C) nge-distillation, kwaye ke enye i-dienes efunekayo, i-monocyclopentadiene ihlukaniswe ukutsalwa kwesinyibilikisi.Le ndlela ithatha inzuzo yeempawu ukuba i-cyclopentadiene (CPD) ilula ukuyinciphisa ngaphezu kwamanye amaqhezu e-C5.Kwaye ke i-dicyclopentadiene (DCPD) ihlukaniswe kwi-C5 i-fractions nge-distillation kuba indawo yethu yokubilisa iphezulu kakhulu kunezinye i-C5 hydrocarbons.
I-Dicyclopentadiene(DCPD)'s Employment Directions
Thina (dicyclopentadiene / DCPD) sibandakanyeka kwizinto ezisisiseko zemichiza ekrwada kunye nemathiriyeli yesinyithi yepolymer.Kule veki iphelileyo, bendisandula kunika iikhosi zokhokelo lwengqesho kwabo baphumeleleyo abaza kungena kwimarike yomsebenzi.Abantwana bosapho lwe-DCPD banokhetho oluninzi lwemisebenzi.Uninzi lwabo luya kusebenza kumayeza, amayeza okubulala izitshabalalisi, iirasi zokwenziwa, iziqholo, irabha eyenziweyo kunye namanye amasimi.Ziyakwazi ukutshintshwa kwi-adamantane, i-2-Chloro-5-chloromethylpyridine, i-metallocene, i-glutaraldehyde, i-carbamate, i-epoxy resin yokunyanga i-agent, i-flame retardant, i-dicyclopentadiene chloride (i-insecticide), njl. Olu khetho luya kutshintsha imbonakalo yabo kunye neempawu zabo.
Abantu bafumanise ukuba i-resins ye-hydrocarbon eguquliweyo inyuse ukusebenza kwakhona kwi-copolymerizations ngeoyile yokomisa, kwaye ivelise iireyini zepeyinti ezinomgangatho wokomisa ophuculweyo, iglosi kunye nobunzima.ngoko ke ii-DCPD zinolunye ukhetho.Banokujoyina inkampani ye-hydrocarbon resins elungisiweyo.Xa besebenza kule ntsimi, baya kudlala indima enkulu kwiinki, i-adhesives kunye neepeyinti.
Ikamva leDicyclopentadiene(DCPD).
Silusapho olungenakungahoywa ukuba singabanini bethu kwixabiso lezoqoqosho elinokubakho kunye namathemba abanzi ophuhliso.Abantu kwihlabathi jikelele benza uphando oluninzi kwi-DCPD kwaye babhale amanqaku.Imeko yethu yengqesho iya ibangcono kwaye ishushu, kwaye asohlukani nobomi bomntu.
