Kwiminyaka yakutshanje, izakhiwo eziphakamileyo zezakhiwo zikhule ngokukhawuleza kwaye zikhawuleze, kwaye zaphucuka kwekhonkrithi ineemfuno eziphezulu nezingaphezulu zokuhlambela, ukugcinwa kwamanzi kunye nozinzo kwikhonkrithi ebhalwe yekhonkrithi elandelwayo. Ukwenzela ukuba uhlangabezane neemfuno zokwakha zezakhiwo zokunyuka kwekhonkrithi ephezulu, ezilungisiweyo zekhonkrithi zinyanzelekile ukuba zibe neemfuno eziphezulu neziphezulu zekhonkrithi ezilandelwayo. Ke ngoko, kwiminyaka yakutshanje, ukusetyenziswa kweI-Polycarboadiye yaxhaphake ngakumbi, ixhaphake kakhulu, ngokuthe ngcembe isebenzisa isicelo se-Naphthalene. Nangona kunjalo, nangona kunjaloI-Polycarboadisombulula iimfuno zokunyuka okuphezulu kwempompo kunye nokuqina kwekhonkrithi elungele,I-PolycarboadInomdla kakhulu ekuqhubeni phambili ngezinto ezingafunekiyo zekhonkrithi kunye neemeko zokusingqongileyo, ezikhokelela kwiingxaki ezahlukeneyo ekwakhiweni kwekhonkrithi. Umzekelo, ukuthambeka kwekhonkrithi egxunyelweyo elungele inyuke, ngakumbi ebusika, le nto ixhaphakile, kwaye isikhululo sokudibana nomxube esingumxube sihlala sisonjululwe kakhulu.
Izizathu zihlalutywa ngolu hlobo lulandelayo:
1. Kugqitywe ngohlobo lwesakhiwo semolekyuli esisebenzayo seqela le-polycarbox Phantsi kwendalo yobushushu ephantsi, isantya sezinto ezibonakalayo ezibonakalayoI-PolycarboadAmaqela e-Molecular asebenza kancinci, kwaye ikhonkrithi ngaphandle komatshini ayinakubonisa ngokwenyani iI-Polycarboad. Emva kwexesha lokuhamba,I-PolycarboadUkudlala ngokugqibeleleyo indima, kukhokelela kwi-slump yekhonkrithi kwisiza ukwandisa okanye ukwahlulahlula;
2. Ebusika, i-steam okanye i-heatsion yombane isetyenziselwa ukufudumeza amanzi okuxuba ngexesha lemveliso kwisikhululo sokuxuba. Nangona kunjalo, inqanaba lokuhamba kwamanzi liyakhawuleza ngexesha lenkqubo yokuvelisa, kwaye amaqondo obushushu anyukayo amanzi ashushu awakwazi ukuqhubeka, okukhokelela kumaqondo omninzi kwiqondo lokuxuba langaphambili kunye nezingasemva, ezichaphazela ixesha le-adsen Iimolekyuli zokuncomela kunye neemolethi zesamente, kwaye ke zichaphazela utshintsho lwekhonkrithi;
3. Ngenxa yomthamo omkhulu wemveliso kwisikhululo sokuxuba, ukuze kuhlangatyezwane nemfuno yokuhambisa, ixesha lokuxuba lekhonkrithi lifinyezwe, kukhokelela kwikhonkrithi yekhonkrithi ngaphandle komatshini ayibonakali iI-Polycarbanded ye-Polycarbacker
Izisombululo:
(1) Yenza iimvavanyo zokuhambelanaI-Polycarboadkunye nezinto zesamente ezisetyenziselwa kwangaphambili ukuqinisekisa ukuba azihambelani neemfuno zokuncitshiswa kwamanzi kodwa nazo iimfuno ezifanelekileyo zekhonkrithi;
(2) Zama ukunciphisa ukutshintsha kobushushu bokuxuba kwamanzi asetyenzisiweyo kwisikhululo sokuxuba. Ukuba iimeko zemvume, zisete iitanki ezimbini zokutshisa ukufudumeza;
(3) Yongeza ixesha lokudibanisa ukuqinisekisa ukubaI-Polycarboadkunye nezixhobo zesamente zinamasuntswana aneleyo;

IXESHA LOKUQALA: FEB-19 ukuya ku-1525
