Iyini i-Diethyl Methyl Toluene Diamine Esetshenziselwa Ezinhlelweni Zanamuhla ze-Polyurethane?
Wake wazibuza ukuthi yini eyenza amapulasitiki athile aqine, aguquguquke, futhi ahlale isikhathi eside? Impendulo ivame ukutholakala ku-chemistry ngemuva kwezinto. Ikhemikhali eyodwa ebalulekile ezinhlelweni ze-polyurethane i-Diethyl Methyl Toluene Diamine (evame ukubizwa nge-DETDA). Nakuba kungase kuzwakale kuyinkimbinkimbi, lo mdlalo oyinhlanganisela...Funda kabanzi -
Ukulwa nezinduna ngeMagnesium Ascorbyl Phosphate
Izinduna kungaba inkinga yesikhumba ekhungathekisayo futhi eqhubekayo, ethinta abantu babo bonke ubudala. Nakuba ukwelapha kwezinduna zendabuko kuvame ukugxila ekomisweni kwesikhumba noma ekusebenziseni amakhemikhali anokhahlo, kunesinye isithako esithola ukunakwa ngenxa yekhono laso lokwelapha izinduna kuyilapho kukhanyisa i-comp...Funda kabanzi -
I-Ethyl Silicate vs. I-Tetraethyl Silicate: Umehluko Obalulekile
Ezweni lezinhlanganisela zamakhemikhali, i-ethyl silicate ne-tetraethyl silicate zivame ukukhulunywa ngazo ngokusetshenziswa kwazo okuhlukahlukene kanye nezakhiwo eziyingqayizivele. Yize zingase zibonakale zifana, izici zazo ezihlukene kanye nokusetshenziswa kwazo kwenza ukuqonda umehluko ube ubalulekile kunoma ubani osebenza nabo ...Funda kabanzi -
Ukuncibilika kwe-Tetraethyl Silicate Emanzini naseziNxulwini
Ukuqonda izici zokuncibilika kwe-tetraethyl silicate (TES) kubalulekile ezimbonini ezisebenzisa le nhlanganisela eguquguqukayo embotsheni, ezintweni ezinamathelayo, ezitsheni zobumba, nasezintweni zikagesi. I-TES, eyaziwa nangokuthi i-ethyl silicate, isandulela se-silica esivame ukusetshenziswa esiziphatha ngendlela ehlukile kuzincibilikisi ezihlukahlukene. Ngi...Funda kabanzi -
Ukusetshenziswa Okuphezulu Oku-5 Kwe-Tetraethyl Silicate Okufanele Ukwazi
Emhlabeni wamakhemikhali ezimboni, i-tetraethyl silicate (TES) iyinhlanganisela eguquguqukayo kakhulu esetshenziswa ezimbonini ezahlukahlukene. Eyaziwa nangokuthi i-ethyl silicate, ivamise ukusetshenziswa njenge-ejenti exhumanisayo, i-binder, kanye nesandulela sezinto ezisekelwe ku-silica. Izakhiwo zayo ezihlukile ziyenza ibaluleke...Funda kabanzi -
I-Diethyl Methyl Toluene Diamine: ikhemikhali eguquguqukayo enezinhlobonhlobo zezinhlelo zokusebenza
I-China Fortune Chemical, umkhiqizi ohamba phambili wamakhemikhali amahle, yenze ezibukwayo embonini ngekhwalithi ephezulu ye-Diethyl Methyl Toluene Diamine (DMTD). Le khemikhali enemisebenzi eminingi ikhiqizwa ngenqubo eqinile eqinisekisa ubumsulwa nokusebenza kwayo. Ukukhiqizwa kwe-DMTD kuyaqala ...Funda kabanzi -
Umoya onamandla wokuvikelwa kwemvelo, njengokuvinjelwa kokukhiqiza ngenkathi yokushisa, wahlukumeza kakhulu izimboni eziningi ezifana nensimbi.
Umoya onamandla wokuvikelwa kwemvelo, njengokuvinjelwa kokukhiqiza ngenkathi yokushisisa, wahlukumeza kakhulu izimboni eziningi ezifana nensimbi, imboni yamakhemikhali, usimende, i-electrolytic aluminium, njll. Abangaphakathi kwemboni bakholelwa ukuthi ukuphela konyaka imakethe yensimbi izoba esinye isiyaluyalu, izintengo noma...Funda kabanzi -
Ushukela oluhlaza ushaqisa ukwesekwa kwenselelo yasekhaya
Ushukela omhlophe Ushukela oluhlaza ushaqisa inselele yasekhaya ukwesekwa Ushukela ongakaphekiwe uguquguquke kancane izolo, okukhuliswe okulindeleke ukuthi kube nokwehla kokukhiqizwa kukashukela waseBrazil. Inkontileka eyinhloko ifinyelele ku-14.77 cents iphawundi futhi yehle yafika ku-14.54 cents ngephawundi. Intengo yokugcina yokuvala yenkontileka enkulu yenyuka...Funda kabanzi -
Amandla amasha okuqhuba uguquko nokuthuthukiswa kwezimboni
Ezigabeni ezintathu zokuqala, umnotho omkhulu wasekhaya wawusebenza kahle, hhayi nje ukufeza umgomo wokufika endaweni ethambile, kodwa futhi nokugcina inqubomgomo yezimali ephusile kanye nokusebenzisa zonke izinqubomgomo zokulungiswa kwesakhiwo, izinga lokukhula kwe-GDP liye lasimama kancane.
