Ipulasitiki… Funda kabanzi
Isibonelo Sombuzo Wengxoxo Ngepulasitiki: Ukuhlola Izinzuzo Nemiphumela Yezinto Ezidumile Kakhulu Ipulasitiki, enye yezinto ezijwayelekile kakhulu ekuphileni kwethu kwansuku zonke, ilethe izinzuzo eziningi, kodwa futhi iphakamisa izinkinga eziningi ezibalulekile zemvelo. Kulesi sihloko, sizohlola ngokujulile ipulasitiki, siqonde izinzuzo zayo, sibukeze izinselele zemvelo ebhekene nazo, futhi sihlole umqondo... Funda kabanzi
Imibuzo Eyisibonelo Exoxa Ngobudlelwano Phakathi Kwesakhiwo Nezakhiwo Zama-Polymer Isingeniso Ama-polymer ayizinto eziyingqayizivele ezakhiwe ngamaketanga amade, aphindaphindayo ama-molecule abizwa ngokuthi ama-monomers. Izakhiwo zama-polymer zingahluka kakhulu, futhi lokhu kuhlukahluka kuthinta ngqo izakhiwo zazo zomzimba. Ukuqonda ukuthi isakhiwo sama-polymer sithinta kanjani izakhiwo zazo kubalulekile ezinhlobonhlobo zezicelo zobuchwepheshe nezimboni. Lesi sihloko… Funda kabanzi
Imibuzo Eyisibonelo kanye Nengxoxo Yezinhlobo Zama-Polymer I-polymer iyi-molecule enkulu eyakhiwe ngamayunithi amancane ama-molecule abizwa ngokuthi ama-monomers. Ama-polymer asetshenziswa ezinhlobonhlobo zezicelo, kusukela kumapulasitiki nerabha kuya kumafayibha okwenziwa nezinto zokwakha. Ukuqonda ama-polymer kubalulekile kumakhemikhali, isayensi yezinto zokwakha, kanye nezimboni ezahlukahlukene. Lesi sihloko sizoxoxa ngezinye ze... Funda kabanzi
Imibuzo Nengxoxo Ngesibonelo Sokwakheka Kwe-Condensation Polymerization Ukwakheka kwe-condensation polymerization uhlobo lokusabela kwe-polymerization olukhiqiza ama-polymer ngokuxhumanisa ama-monomer ngokususwa kwama-molecule amancane, njengamanzi, i-methanol, noma i-HCl.
