Izizathu zokuthuthukiswa okusheshayo kweziqinisi ezintsha ze-calcium zinc ezinobungani bemvelo ziyi
Lapho sikhiqiza imikhiqizo yepulasitiki, sisebenzisa ama-stabilizers amaningi, phakathi kwawo ama-stabilizer ahlanganisiwe asetshenziswa kakhulu. Ngisho noma izithasiselo zikasawoti omthofu zingabizi futhi zinokuzinza okuhle kokushisa, ziye zasetshenziswa kabanzi. Nokho, i...Funda kabanzi -
Amaphuzu abalulekile okulawula inqubo yesilawuli esigwebulile se-PVC
Isilawuli sokukhihliza amagwebu se-PVC singasisiza silethe izakhiwo ezinhle ngesikhathi sokukhiqiza nokucubungula i-PVC, senze ukusabela kwethu kuqhubeke kangcono futhi sikhiqize imikhiqizo esiyifunayo. Kodwa-ke, sidinga futhi ukunaka izivumelwano ezimbalwa ezibalulekile zezimboni ...Funda kabanzi -
Uyini umehluko phakathi kwezinsiza zokucubungula ze-PVC, ama-plasticizers, nezinto zokuthambisa?
Ngenxa yokuthi izinsiza zokucubungula i-PVC zihambisana kakhulu ne-PVC futhi zinesisindo esilinganiselwe samangqamuzana (cishe (1-2) × 105-2.5 × 106g / mol) futhi ayikho i-powder yokugqoka, zingaphansi kokushisa nokuxuba ngesikhathi sokubumba. Baqale bathambe futhi...Funda kabanzi -
Izinzuzo kanye nokubi kwe-calcium zinc stabilizers
Phakathi nenqubo ye-plasticization, i-calcium zinc stabilizers ine-electronegativity ephezulu, futhi ama-node acute we-PVC resin anobudlelwane obuthile, akha ama-bond energy complexes aqinile. Iziqinisi ze-calcium zinc zingahlukaniswa zibe...Funda kabanzi -
Wonke umuntu uyazi ngezinsiza zokucubungula ze-PVC. Yiziphi izinkinga ngezinsiza zokucubungula ze-PVC embonini?
1. Ubuchwepheshe be-MBS nokuthuthukiswa kuhamba kancane, futhi imakethe ibanzi, kodwa isabelo semakethe semikhiqizo yasekhaya siphansi. Nakuba sekudlule iminyaka engaphezu kwengu-20 yentuthuko, imboni yasekhaya ye-MBS njengamanje ...Funda kabanzi -
