Sawubona, woza uzobonisana nemikhiqizo yethu!

Izinga elisha le-ASTM lisekela ukusetshenziswa kwe-silica ethayini, likhuthaza ukusimama

Kuzosetshenziswa izinga elisha le-ASTM ukuhlola ikhwalithi ye-silica, impahla eluhlaza eyenza isisekelo samasondo “aluhlaza”.Izinkampani zamathaya kanye nabakhiqizi be-silica kuzoba abasebenzisi abayinhloko bezinga elisha (i-D8016, Indlela Yokuhlola Ye-silica, I-Precipitated, Hydrated - Sears Number).Ngokusho kwelungu le-ASTM u-Jorge Lacayo-Pineda, ubuchwepheshe be-silica buthuthukisa ukusebenza ekuqineni kwamasondo ngaphandle kokonakala ekusebenzeni kwamabhuleki.Lokhu kuholela ekusebenzeni kahle kukaphethiloli, kanye nokuncipha kokuphuma kwe-carbon dioxide ezimotweni.Izinkampani zenjoloba, abasebenzisi abakhulu be-silica enciphile, zingathuthukisa imininingwane yazo futhi ziqinisekise ikhwalithi yomkhiqizo ngokuhlola izinga elisha, usho kanje.Ikomidi elincane le-ASTM elidale i-D8016 lihlela ukwenza ukuhlolwa kwe-robin nxazonke entwasahlobo ezayo ukuze lihlole ukunemba kwezinga elisha.Amalebhu ezinkampani zenjoloba, abakhiqizi be-silica nezikhungo zemfundo bayakhuthazwa ukuthi bajoyine.Abahlanganyeli ocwaningweni bazonikezwa amasampula ukuze bawahlaziye ngokwezinga elisha.

I-silica enciphile

I-Bonding, i-anti adhesion, i-anti caking, i-coagulation, ukukhululwa okulawulwayo, umthwali, usizo lokugeleza, ukuthuthukisa umphumela wokunyathelisa, isenzo somshini, izithasiselo ezikhethekile ze-thermoplastic, ukuqinisa, ukulawulwa kwe-rheological nokuba mhlophe.I-Hydrophobic silica ephathwa ngokuguqulwa kwendawo incibilika kalula emafutheni.Lapho isetshenziswa njenge-filler yokuqinisa ku-raber namapulasitiki, amandla emishini kanye nokumelana nezinyembezi kwemikhiqizo yayo kuzothuthukiswa kakhulu.

I-silica enciphayo inezinhlobonhlobo zokusetshenziswa, futhi imikhiqizo ehlukene inokusetshenziswa okuhlukile.Njenge-ejenti eqinisayo enhle yenjoloba yokwenziwa, ukusebenza kwayo okuqiniswayo kungokwesibili kuphela kumnyama wekhabhoni, futhi kungcono nakakhulu kunomnyama wekhabhoni ngemuva kokwelashwa okuphezulu nokufanelekile.Ifaneleka ngokukhethekile ukukhiqiza imikhiqizo yerabha emhlophe, umbala nombala okhanyayo.Isetshenziswa njenge-thickener noma i-thickener, i-ejenti ehlanganisayo kawoyela wokwenziwa kanye nopende wokuvikela, i-ejenti efiphala kapende, i-ejenti ye-thixotropic yezinto zokupakisha ze-electronic component, i-precipitant ye-phosphor ngesikhathi sokumbozwa kwesikrini se-fluorescent, isigcwalisi sepuleti lerabha eliphrinta umbala kanye ne-ejenti yokukhulula isikhunta ukuze kusakazwe. .Ukwengeza ku-resin kungathuthukisa izakhiwo zokuvikela umswakama kanye nokufakwa kwe-resin.Ukugcwalisa imikhiqizo yepulasitiki kungakhuphula ukumelana kwe-skid nokumelana nowoyela.
