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 -
Ukumelana Nesimo Sezulu Okubi? Kukhona okudingeka ukwazi nge-PVC
I-PVC iyipulasitiki evamile evame ukwenziwa ibe amapayipi nezinto zokufakelwa, amashidi namafilimu, njll. Ishibhile futhi iyakwazi ukubekezelela amanye ama-asidi, ama-alkali, usawoti, kanye nezinyibilikisi, okwenza ifaneleke kakhulu ukuthintana nezinto ezinamafutha. Ingenziwa ibe nokubukeka okusobala noma okungacacile...Funda kabanzi -
Yiziphi izinhlobo zama-Antistatic Agents? -Izixazululo ze-Antistatic ezenziwe ngokwezifiso ezivela ku-NANJING REBORN
Ama-antistatic agents aya ngokuya edingeka ukuze kuxazululwe izinkinga ezifana nokumuncwa kwe-electrostatic kupulasitiki, ama-short circuits, kanye nokukhishwa kwe-electrostatic kuma-electronics. Ngokwezindlela ezahlukene zokusebenzisa, ama-antistatic agents angahlukaniswa ngezigaba ezimbili: izithasiselo zangaphakathi kanye ne-external...Funda kabanzi -
ISIVIKELI SE-POLYMER: ISINYATHELI SE-UV
Isakhiwo sama-molecule sama-UV absorbers ngokuvamile siqukethe ama-double bond ahlanganisiwe noma ama-aromatic rings, angamunca imisebe ye-ultraviolet yama-wavelength athile (ikakhulukazi i-UVA ne-UVB). Lapho imisebe ye-ultraviolet ikhanyisa ama-molecule amuncayo, ama-electron kuma-molecule aguquka esuka emhlabathini...Funda kabanzi -
Ukuhlukaniswa kanye namaphuzu okusetshenziswa kwama-ejenti okulinganisa ukumboza
Ama-elevator asetshenziswa ekumbozweni ngokuvamile ahlukaniswa ngama-solvents axubile, i-acrylic acid, i-silicone, ama-polymer e-fluorocarbon kanye ne-cellulose acetate. Ngenxa yezici zayo zokucindezeleka okuphansi kobuso, ama-elevator awakwazi nje ukusiza ukumbozwa ukuthi kulingane, kodwa futhi angabangela imiphumela emibi. Ngesikhathi sokusetshenziswa, ...Funda kabanzi -
Iyini imfanelo yokulinganisa yezingubo?
Incazelo yokulinganisa Impahla yokulinganisa yengubo ichazwa njengekhono lengubo lokugeleza ngemva kokusetshenziswa, ngaleyo ndlela kukhulisa ukususwa kwanoma yikuphi ukungalingani kwendawo okubangelwa inqubo yokufaka. Ngokukhethekile, ngemva kokusetshenziswa kwengubo, kuba nenqubo yokugeleza kanye...Funda kabanzi -
Yini ethinta ukuhlanzwa kwezingubo?
Ukusula ifoam yikhono lokusula ifoam elikhiqizwa ngesikhathi sokukhiqiza kanye nenqubo yokusula.
