I-Resin Evimbela Amalangabi
Njengoba izindleko zokukhiqiza kanye nokuthuthukiswa kobuchwepheshe bokusetshenziswa kwe-resin kukhuphuka, izimboni eziningi ze-resin zisebenza ku-resin engashisi ilangabi ukuze zivumelane nesidingo samakhasimende. Ukwengeza i-ATH enqubweni yokukhiqiza i-resin kunganciphisa izindleko zokukhiqiza kanye nenqubo yeklayenti, kuthuthukise inani elengeziwe kanye nenzuzo yokukhiqiza yefektri ye-resin. Le nqubo yokukhiqiza inesidingo esikhulu solwazi lwe-ATH lwefektri ye-resin, ngoba idinga ukugwema imvula ye-ATH.
Imabula Yokwenziwa
I-aluminium hydroxide iyindlela engcono kakhulu yokugcwalisa imabula yokwenziwa, i-ATH kulula ukuyifinyelela indinganiso yokuvimbela ilangabi yemabula yokwenziwa ngoba ivimbela ilangabi kanye nempahla yokugcwalisa ephezulu. Izakhiwo ezihlukile zokukhanya (inkomba yokubuyisa: 1.57) zenza umkhiqizo ube ngokoqobo. Ukumelana namabala okuhle kakhulu kanye nokumelana nokuguga kwemabula yokwenziwa kubangela izakhiwo zamakhemikhali ezizinzile ze-ATH. Ingenza imabula yokwenziwa esezingeni eliphezulu ibe yinhle kunemabula yemvelo nge-cpmpound efanele yobukhulu bezinhlayiya, i-pigment, izithasiselo.
Ibhodi Yokuvimbela I-Rubber-Plastic
I-ATH ingavimbela ukubhema, amaconsi omlilo, ukwakheka kwengqimba ye-oxide eningi ngenkathi ishiswa. Futhi umphumela we-ATH wokubambisana nge-ejenti ye-foam wenza amabhamuza abe ngokugcwele.
Ibhodi Lokuvimbela Ukushisa
I-aluminium hydroxide yayisetshenziswe kakhulu ebhodini lokufaka i-tps. Ukusetshenziswa kobuchwepheshe be-microphase composite ku-TPS, kusetshenziswa i-gule yokuvimbela umlilo ukugoqa zonke izinhlayiya ze-foam eziphilayo. Ukumboza izinhlayiya ngayinye ene-foam nge-coating evimbela umlilo, i-foam kanye ne-compression molding. I-ATH iyisakhi esiyinhloko sokuvimbela umlilo se-colloid evimbela umlilo.
Isitini Somlilo
Izitini ezingashisi ezenziwe nge-alpha alumina ezinokumelana nokushisa okuphezulu zilula ngesisindo, amandla amakhulu angacindezeleki, ukuhanjiswa kokushisa okuphansi, ukuncishiswa kwevolumu encane, ukumelana nokushaqeka kokushisa okuphezulu. Isendlalelo Sokufudumeza semishini yokushisa ephezulu, isithando sisebenza ngqo elangeni, ulwelwesi lwemishini yokushisa enembile., asifanele ukuxhumana ngqo noketshezi lwesithando kanye ne-slag, ukuzinza okuphezulu ekunciphiseni umoya. Izinga lokushisa lokusebenza lomkhiqizo lingafinyelelwa ku-1650 ~ 1800℃ kuye ngobumsulwa.
Ucingo Nekhebula
Isinyathelo esibaluleke kakhulu ekwelashweni kwentambo nekhebula ngenxa yokushisa komlilo ukufaka i-filler eshisayo, izinga lokusha kwe-polymer lingancishiswa. Ngakho-ke, i-aluminium hydroxide enomsebenzi wokushisa komlilo, umsebenzi wokucindezela intuthu kanye ne-inertia yamakhemikhali, okungeyona into enobuthi sekuyindlela engcono kakhulu. Ukwengeza ama-filler angaphili kuzothinta izakhiwo zemishini ezifana namandla okudonsa ezinto zekhebula, kungancishiswa ngokusebenzisa imikhiqizo ephathwe phezulu.
Izinto Ezihlanganisiwe ze-SMC/BMC
Izinhlanganisela ze-SMC/BMC zisetshenziswa kabanzi kwizesekeli ezisebenzayo zesitimela esinejubane eliphezulu, izindlu zomoya opholile, izinkinobho zikagesi kanye neminye imikhakha. Zonke lezi zinsimu zidinga ukuvikelwa kwemvelo okuphezulu kanye nokubambezeleka komlilo kwezinhlanganisela, ukuvikelwa kwemvelo kanye nezakhiwo zokubambezeleka komlilo ze-aluminium hydroxide kwenza kube yinto eyinhloko yokubambezeleka komlilo ezintweni ezihlanganisiwe, ngemva kweminyaka eminingi yokuthuthukiswa, lolu hlelo lokusebenza seluvuthiwe kakhulu, ukukhetha usayizi wezinhlayiya ezifanele kungenza inani lokwengeza lifinyelele ngaphezu kwama-30% wekhwalithi iyonke.
Isigcwalisi Sokushisa Esiqhuba Ukushisa
I-alumina yokushisa okuphezulu inokumelana okuhle nokuguguleka, ukumelana nokushisa kanye nokufakwa kokushisa, ngesikhathi esifanayo inokuqhuba ukushisa, ukusebenza kahle okuphezulu uma kuqhathaniswa nezinye izigcwalisi zokushisa. Njengesigcwalisi sokushisa, isetshenziswa kabanzi ezintweni zokugcwalisa ze-elekthronikhi, ijeli ye-silica eqhuba ukushisa, i-Pad eshisayo. Ukuqhuba kwayo ukushisa kuhlobene nokuma kwezinhlayiya kanye nenani lokwengeza, ukuguquguquka okuphezulu kuyadingeka ukunciphisa umphumela ku-viscosity yesistimu. Uma isondele kakhulu ku-sphere, ukuguquguquka okuphezulu kanye nenani lokwengeza. Ukusetshenziswa okuhambisanayo nezinye izigcwalisi zokushisa kungafeza ukuqhuba ukushisa okuphumelelayo.
