Isixazululo se-reagent "inkemba esika nhlangothi zombili", futhi ibhodlela lebhodlela lokuphepha lakha isivikelo
Izinyibilikisi ezisebenza ngamandla zingamathuluzi abasebenzi baselabhorethri futhi ziwumthombo wezingozi zokuphepha. Isimo selabhorethri: 1. Ukusetshenziswa kwenani elikhulu lezincibilikisi eziphilayo kubangela ukuguquguquka kwe-solvent; 2. Azikho izindlela zokuvikela ukuphepha, iphunga linamandla, futhi lithinta impilo yezisebenzi; 3. I...Funda kabanzi -
Ama-reagents aselabhorethri ayi-17 anobuthi kakhulu, ungadeleli!
I-DMSO DMSO i-dimethyl sulfoxide, enezinhlobonhlobo zokusetshenziswa. Isetshenziswa njenge-solvent ye-acetylene, ama-hydrocarbons anephunga elimnandi, i-sulphur dioxide namanye amagesi, kanye ne-solvent ye-acrylic fiber spinning. Kuyi-solvent ye-polar engeyona i-protonic ebaluleke kakhulu encibilika kuyo yomibili ...Funda kabanzi -
Umehluko Phakathi Kwenayiloni 6 neNyiloni 66
Iyini inayiloni 6 nenayiloni 66 Inayiloni 6 kanye nenayiloni 66 yimikhiqizo esemqoka yenayiloni. Inayiloni iqinile futhi ayigugi, futhi amandla ayo angaqhathaniswa ngisho nalawo ocingo lwensimbi oluwugqinsi olufanayo; Inayiloni engu-15% ehlanganiswe novolo ingakhuphula ukumelana kwayo nokugqoka izikhathi ezingu-3.5; ngaphandle kwe-polypropylene ...Funda kabanzi -
Ukusetshenziswa okulungile kanye nezinyathelo ze-volumetric flask
Ama-flasks e-Volumetric asetshenziselwa ngokuyinhloko ukulungisa ngokunembile izixazululo zokuhlushwa okuthile. Ziyibhodlela lengilazi elincanyana, elimise okwepheya, eliyisicaba elinesivalo esiphansi. Kukhona uphawu entanyeni yebhodlela. Lapho uketshezi olusebhodleleni lufinyelela uphawu ezingeni lokushisa elishiwo,...Funda kabanzi -
