I. Incazelo yezithasiselo zepulasitiki Ipulasitiki...Funda kabanzi -
Ukunciphisa Izindleko Nokuthuthukiswa Kokusebenza Kwe-Silica Ezimbozweni
Ukusetshenziswa kwe-silica ezimbozweni kuhilela kakhulu ukuthuthukisa ukunamathela, ukumelana nesimo sezulu, izakhiwo zokulwa nokuqina, kanye nokuthuthukisa i-thixotropy. Ifaneleka ezimbozweni zezakhiwo, ezimbozweni ezisekelwe emanzini, kanye nopende we-acrylic resin. ...Funda kabanzi -
Abakhiqizi Abaphezulu Be-Optical Brightener
Njengoba isidingo sokukhanyisa okukhanya sikhula (ama-ejenti okukhanyisa okukhanya), ukuze kube lula ukuthola abahlinzeki abafanelekile, sabelane ngabakhiqizi abaphezulu be-optical brighteners. Ama-optical brighteners (fluoresc...Funda kabanzi -
Kungani Sidinga Ama-Deactivator Ethusi?
Isivimbeli sethusi noma isivimbeli sethusi siyisengezo esisebenzayo esisetshenziswa ezintweni ze-polymer ezifana nepulasitiki nerabha. Umsebenzi waso oyinhloko ukuvimbela umphumela wokuguga wama-ion ethusi noma ethusi ezintweni, ukuvimbela ukuwohloka kwezinto, ukushintsha kombala, noma ukuwohloka kwempahla...Funda kabanzi -
Isayensi Yesikrini Sokuvikela Ilanga: Isivikelo Esibalulekile Emisebeni Ye-UV
Izifunda eziseduze ne-equator noma ezindaweni eziphakeme zinemisebe enamandla ye-ultraviolet. Ukuchayeka isikhathi eside emisebeni ye-ultraviolet kungaholela ezinkingeni ezifana nokushiswa yilanga kanye nokuguga kwesikhumba, ngakho-ke ukuvikelwa kwelanga kubaluleke kakhulu. I-sunscreen yamanje itholakala kakhulu ngokusebenzisa indlela yokumbozwa ngokomzimba noma ...Funda kabanzi -
Ukubuka Konke Kwezithasiselo Zokumboza
Incazelo kanye nencazelo Izithasiselo zokumboza ziyizithako ezingezwe ekumbozeni ngaphezu kwezinto eziyinhloko ezakha ifilimu, ama-pigment, ama-filler, kanye nezinyibilikisi. Ziyizinto ezingathuthukisa kakhulu isici esithile sefilimu yokumboza noma yokumboza. Zisetshenziswa ngenani elincane...Funda kabanzi -
Isixazululo Sokulwa Nokuguga se-Polyamide (Nylon, PA)
I-Nylon (i-polyamide, i-PA) iyipulasitiki yobunjiniyela enezakhiwo ezinhle kakhulu zomshini nezokucubungula, phakathi kwazo i-PA6 ne-PA66 kuyizinhlobo ezivamile ze-polyamide. Kodwa-ke, inemikhawulo yokumelana nokushisa okuphezulu, ukuqina kombala okungekuhle, futhi ithambekele ekumuncweni komswakama kanye ne-hydrolysis. I-Takin...Funda kabanzi -
Imakethe yomhlaba wonke ye-Nucleating Agent ikhula kancane kancane: igxile kubaphakeli abasafufusa baseShayina
Ngonyaka odlule (2024), ngenxa yentuthuko yezimboni ezifana nezimoto nokupakisha, imboni ye-polyolefin ezifundeni zase-Asia Pacific naseMpumalanga Ephakathi ikhule kancane kancane. Isidingo sama-nucleating agents sikhule ngokufanayo. (Kuyini i-nucleating agent?) Ukuthatha iShayina njenge ...Funda kabanzi -
