Mulingo watsopano wa ASTM udzagwiritsidwa ntchito kuyesa mtundu wa silika, zopangira zomwe zimapanga maziko a matayala "obiriwira".Makampani a matayala ndi opanga silika adzakhala omwe adzagwiritse ntchito kwambiri muyeso watsopano (D8016, Njira Yoyesera ya Silika, Yopumira, Yothiridwa - Nambala ya Sears).Malinga ndi membala wa ASTM Jorge Lacayo-Pineda, ukadaulo wa silica umapangitsa kuti magwiridwe antchito azitha kugubuduza tayala popanda kuwonongeka kwa braking.Izi zimapangitsa kuti mafuta azigwira bwino ntchito, komanso kuchepetsa mpweya wa carbon dioxide m'galimoto.Makampani a mphira, omwe amagwiritsa ntchito kwambiri silika wamvula, amatha kuwongolera momwe amapangira ndikuwonetsetsa kuti zinthu zili bwino poyesa muyeso watsopano, akutero.Komiti yaying'ono ya ASTM yomwe idapanga D8016 ikukonzekera kuyesa kuyesa kwa robin kumapeto kwa masika kuti awone kulondola kwa muyezo watsopano.Ma lab amakampani a mphira, opanga silika ndi mabungwe ophunzira akulimbikitsidwa kuti alowe nawo.Otenga nawo mbali mu kafukufukuyu adzapatsidwa zitsanzo kuti azisanthula molingana ndi muyezo watsopano.
Kuchuluka kwa silika
Kumangirira, anti adhesion, anti caking, coagulation, kumasulidwa koyendetsedwa, chonyamulira, kuthandizira kuyenda, kuwongolera kusindikiza, kuchitapo kanthu kwamakina, zowonjezera zowonjezera za thermoplastic, kulimbikitsa, kuwongolera kwa rheological ndi kuyera.Silika ya Hydrophobic yopangidwa ndi kusinthidwa kwapamwamba imasungunuka mosavuta mumafuta.Ikagwiritsidwa ntchito ngati kulimbikitsa zodzaza mu mphira ndi mapulasitiki, mphamvu zamakina ndi kukana kugwetsa kwazinthu zake zimakhala bwino kwambiri.
Silika wa precipitated ali ndi ntchito zosiyanasiyana, ndipo zinthu zosiyanasiyana zimakhala ndi ntchito zosiyanasiyana.Monga chothandizira chabwino chothandizira mphira wopangira, kulimbitsa kwake kumakhala kwachiwiri kokha kwa wakuda wakuda, komanso kuposa mpweya wakuda pambuyo pa chithandizo chapamwamba komanso choyenera chapamwamba.Ndizoyenera kwambiri kupanga zoyera, zamtundu ndi zowala za rabara.Amagwiritsidwa ntchito ngati thickener kapena thickener, kusakaniza wothandizila wa kupanga mafuta ndi insulating utoto, dimming wothandizila utoto, thixotropic wothandizila zamagetsi chigawo ma CD zipangizo, precipitant wa phosphor pa fulorosenti chophimba ❖ kuyanika, filler wa mtundu kusindikiza mphira mbale ndi nkhungu kumasulidwa wothandizila kuponyera. .Kuphatikizira mu utomoni kumatha kupititsa patsogolo chitetezo cha chinyezi komanso kutchinjiriza kwa utomoni.Kudzaza zinthu zapulasitiki kumatha kukulitsa kukana kwa skid komanso kukana mafuta.
