Izizathu zokuthuthukiswa okusheshayo kwezinzinzisi ezintsha ze-calcium zinc ezinobungani nemvelo yilezi:
Uma sikhiqiza imikhiqizo yepulasitiki, sisebenzisa iziqinisi eziningi, phakathi kwazo iziqinisi ezihlanganisiwe ezisetshenziswa kakhulu. Ngisho noma iziqinisi zikasawoti we-lead zishibhile futhi zinokuqina okuhle kokushisa, ziye zasetshenziswa kabanzi. Kodwa-ke,...Funda kabanzi -
Amaphuzu abalulekile okulawula inqubo yomlawuli we-PVC foaming
Umlawuli we-PVC foam angasisiza ukuthi sithole izakhiwo ezinhle ngesikhathi sokukhiqizwa nokucutshungulwa kwe-PVC, okwenza ukusabela kwethu kuqhubeke kangcono futhi kukhiqize imikhiqizo esiyifunayo. Kodwa-ke, sidinga futhi ukunaka izingqinamba eziningana ezibalulekile zezimboni...Funda kabanzi -
Uyini umehluko phakathi kwezinsiza zokucubungula ze-PVC, ama-plasticizer, kanye nama-lubricant?
Ngenxa yokuthi izinsiza zokucubungula i-PVC ziyahambisana kakhulu ne-PVC futhi zinesisindo sama-molecule esiphezulu (cishe (1-2) × 105-2.5 × 106g/mol) futhi azinawo ufulawa wokumboza, ziyashiswa futhi zixutshwe ngesikhathi senqubo yokubumba. Ziqala zithambe futhi...Funda kabanzi -
Izinzuzo kanye nokungalungi kweziqinisi ze-calcium zinc
Ngesikhathi senqubo yokwenza ipulasitiki, iziqinisi ze-calcium zinc zine-electronegativity ephezulu, kanti ama-node abukhali e-PVC resin anobuhlobo obuthile, akha ama-complexes e-bond energy aqinile. Iziqinisi ze-calcium zinc zingahlukaniswa...Funda kabanzi -
Wonke umuntu uyazi ngezinsiza zokucubungula i-PVC. Yiziphi izinkinga ngezinsiza zokucubungula i-PVC embonini?
1. Ubuchwepheshe nentuthuko ye-MBS kuhamba kancane, futhi imakethe ibanzi, kodwa isabelo semakethe yemikhiqizo yasekhaya siphansi kakhulu. Nakuba isidlule iminyaka engaphezu kwengu-20 yentuthuko, imboni yasekhaya ye-MBS okwamanje...Funda kabanzi -
Yiziphi izici zeziqinisi ze-calcium zinc ezinobungani nemvelo:
Yiziphi izici zeziqinisi ze-calcium zinc ezinobungani nemvelo: Iziqinisi ze-calcium zinc ziyi-nitric oxide synthases ezakhiwe usawoti we-calcium zinc organic, ama-hypophosphite esters, ama-polyether polyols, ama-antioxidants, kanye nezinyibilikisi ze-organic. I-calcium zinc stabil...Funda kabanzi -

Indlela yokuhlola ukwengezwa kwezinto ezingaphili ezinsizakalweni zokucubungula i-ACR: Indlela yokuthola i-Ca2+: Amathuluzi okuhlola kanye nama-reagent: i-beaker; Ibhodlela elibunjwe ngekhoni; I-Funnel; i-burette; Isithando sikagesi; I-ethanol engenamanzi; I-Hydrochloric acid, isixazululo se-buffer se-NH3-NH4Cl, inkomba ye-calcium, i-0.02mol/L ...Funda kabanzi -
Ukuhlaziywa kwezinhlobo eziyinhloko zezinsiza zokucubungula i-ACR
1. Izinsiza zokucubungula ezibanzi: Izinsiza zokucubungula ze-Universal ACR zinganikeza amandla okuncibilika alinganiselayo kanye ne-viscosity yokuncibilika. Zisiza ukusheshisa ukuncibilika kwe-polyvinyl chloride futhi zinokuhlakazeka okuhle kakhulu ngaphansi kwezimo eziphansi zokusika. Ngemuva kokusetshenziswa, ibhalansi efanelekile kakhulu phakathi...Funda kabanzi -
Yiziphi izinkinga zombala ngemva kokuba iziqinisi ze-calcium zinc zithathe indawo kasawoti we-lead?
Ngemva kokuthi isiqinisi sishintshiwe kusuka kusawoti oholayo kuya ku-calcium zinc stabilizer, kulula ukuthola ukuthi umbala womkhiqizo uvame ukuba luhlaza okotshani, futhi kunzima ukufeza ushintsho lombala kusuka koluhlaza okotshani kuya kobomvu.
