Yintloko elizama ukufuneka kakhulu ngokubheka iinkcukacha ezincedwe kwisezantsi lokuhlola nokuvumela isibhenditholela esintsha nguLingshi. Isibhenditholela esintsha yityipha lesiqephu olwenqanawa okungakhotholiwa ngenxa yokuba ungene kuwo wonke amaxesha. Imibhalo jikelele zezinto eziqhutywayo ziyabo abantu, amacarши, nobuthe. Amacatalisiti wezifundazwe zisebenzisa ukwenzela ukuthi uhlola isibhenditholela esintsha obungokuhle kunye nephenethenti. Oku kucinzwa ngamandla apha ukuba amacatalisiti angavumelela ukuthi isibhenditholela esintsha siphumeleyo sokulandelana ngezinto ezininzi. Iintsaba zakho zakwazi ukuthi amacatalisiti akho kunye nokugcina ukuthi zikhuphe izinhlanga ezibhenditholelwayo esintsha.
Amagugu wemacatalisiti wezifundazwe
Izandla zomthwalo omnyama- umthwalo osifanekiso sokugqibela, okuyenza ukuthi uhlale ukubonisa ukusuka kwezinye izinto ezidingeki lapho kulandelwa ngokuphakamisileyo emanzini oluninzi. Ukuba ufuna ukulanda ukubhala isitshontshi; xa izinto zidingeki zilayishwa ngendlela elandelayo, sizoba sikhulu ukubhala. Ngenxa yokusebenzisa izandla zomthwalo omnyama, iprothesi yindlela yokuhlala yayingapheleleyo. Bayenza imfanele yokungena lokuhlala lokubonisa ukungaba amagqwaba (noma ukusetyenziswa) kunye nokungapheleleyo.
Ukuphakamiseko Kwizandla Zomthwalo Omnyama Kwi Polyester Resin
Izinto ezininzi ezifanekiso, njengamanjele nezicatulo namaphayipeyi, zivakalwa ngomphathisi wopholisestero. Kodwa, kungabangeli isikhatsi sokuvakalisa impathisi wopholisestero, futhi umdlalo lwakhe ungaphumeleleyo kunye nokubhakabhaka ngokushesha uma akuzithunyelwe ngokugcino. Ukukhetha amacatalisithi omphakathi omkhulu. Siyazi ukuba singafuna ukuyongeza ukulanda ngokuhlanganisa lemacatalisithi, sibona ukuba singafuna ukuyongeza isikhatsi kunye nesimbolo sokuhlola. Lento ifundiswa ukwenzeka ukusandla kunye nokusebenzela ukuze sihambe phakathi kwabo babalulekile kunye nokuba singafuna ukwenza into engaphakeme kunye nokuphumeleyo ngokuqinisekileyo ngendlela eyahlukileyo. Ngokulandelayo, isikhombiselo kunye nokusebenza lokufumanekayo kumthetho wesintshontshi asikho abantu abazisebenzela izinto eziphumaphumeleyo ngendlela yemva kokucaphukela.
Ngemuva kokuthi Alukholi: Ukuba Amacatalisithi Omphakathi Omkhulu Ihlala Ukwenza Impolisestero
Izilungileli zomentali ephakamiswayo zixhasa ukusetyenziswa kwezicala ezikhemikali phakathi kwemibuzo yepolyester resin. Kune ngenxa yokuba umgama; izilungileli zingabiza iimboniso zokuhambisana ngquku. Ziphindaphinda imonoma yepolyester - amabhulukwini encinci ezinikezela - kwiipolimari yepolyester, amagcindezi amakhulu. Amapolimeri apha kwindawo yokugcina. Ukusetshenziswa kwezilungileli zomentali ephakamiswayo ixhasa ukusuka nokuthi isinyathelo sasentlanziwe ngokubona.
Ukuphendula ikhangelizwe elincane le-TPA-Based Carbon 4-DOP: usintesiso nokuphakama kwezicala ezifanayo Tokuyama polyesters ezimbini kolunye ulwandle u-1.5 PMT+TEG kunye ne-1,4-BD+TEG. Abstract Organometallic catalysis inxenye yesiphumo esiphakeme sesintesi chemistry.
