Isisombululo sokulwa nokwaluphala sePolyamide (Nylon, PA)
I-Nylon (i-polyamide, i-PA) yiplastiki yobunjineli eneempawu ezibalaseleyo zoomatshini nezokucubungula, phakathi kwazo i-PA6 kunye ne-PA66 ziintlobo eziqhelekileyo ze-polyamide. Nangona kunjalo, inemida ekumelaneni nobushushu obuphezulu, ukuzinza kombala okungekho semgangathweni, kwaye ithambekele ekufunxeni umswakama kunye ne-hydrolysis. Ithatha...Funda ngokugqithisileyo -
Imakethi ye-Nucleating Agent yehlabathi iyanda ngokuthe chu: igxile kubaboneleli abasakhasayo baseTshayina
Kunyaka ophelileyo (2024), ngenxa yophuhliso lwamashishini afana neemoto kunye nokupakisha, ishishini le-polyolefin kwimimandla ye-Asia Pacific kunye ne-Middle East liye lakhula ngokuthe chu. Imfuno yee-arhente ze-nucleating iye yanda ngokufanayo. (Yintoni i-arhente ye-nucleating?) Ukuthatha iTshayina njenge ...Funda ngokugqithisileyo -
Ukumelana nemozulu okubi? Kukho into ekufuneka uyazi malunga ne-PVC
I-PVC yiplastiki eqhelekileyo edla ngokwenziwa ibe yimibhobho kunye nezinto zokufakelwa, amashiti kunye neefilimu, njl. Ixabiso layo liphantsi kwaye inokunyamezelana okuthile nezinye ii-asidi, ii-alkalis, iityuwa, kunye nezinyibilikisi, okwenza ukuba ifaneleke ngakumbi ekudibaneni nezinto ezinamafutha. Ingenziwa ibe yimbonakalo ecacileyo okanye engacacanga...Funda ngokugqithisileyo -
Ziziphi iindidi zee-Antistatic Agents? -Izisombululo ze-Antistatic ezenziwe ngokwezifiso ezivela kwi-NANJING REBORN
Ii-antistatic agents ziya zifuneka ngakumbi ukujongana nemiba efana nokufunxwa kwe-electrostatic kwiplastiki, ii-short circuits, kunye nokukhutshwa kwe-electrostatic kwi-electronics. Ngokweendlela ezahlukeneyo zokusetyenziswa, ii-antistatic agents zinokwahlulwa zibe ziindidi ezimbini: izongezo zangaphakathi kunye nezangaphandle...Funda ngokugqithisileyo -
UMKHUSELI WEPOLYMER: ISIFUMANI SE-UV
Ulwakhiwo lwemolekyuli yezifunxi ze-UV ludla ngokuba neebhondi ezimbini ezidityanisiweyo okanye iiringi ze-aromatic, ezinokufunxa imisebe ye-ultraviolet yee-wavelengths ezithile (ngokuyintloko i-UVA kunye ne-UVB). Xa imisebe ye-ultraviolet ikhanyisa iimolekyuli ezifunxayo, ii-elektroni ezikwiimolekyuli ziyaguquka ukusuka emhlabeni...Funda ngokugqithisileyo -
Ukwahlulahlula kunye neendawo zokusetyenziswa kweearhente zokulinganisa ungqimba
Iiarhente zokulinganisa ezisetyenziswa kwiingubo zihlala zahlulwe zibe zii-solvents ezixutyiweyo, i-acrylic acid, i-silicone, ii-fluorocarbon polymers kunye ne-cellulose acetate. Ngenxa yeempawu zayo zoxinzelelo oluphantsi lomphezulu, iiarhente zokulinganisa azinakunceda kuphela ukuba i-coating ifikelele kwinqanaba, kodwa zinokubangela neziphumo ebezingalindelekanga.
