Upfu hwe aluminium hydroxide hwakatsetseka hune mabasa akawanda akadai sekubvisa utsi nekuzadza, uye hunogona kugadzira simba rinodzivirira moto pamwe chete ne phosphorus nezvimwe zvinhu. Inodzivirira moto zvakanyanya mukuchengetedza zvakatipoteredza mumaindasitiri emagetsi, makemikari, tambo, mapurasitiki, rabha nedzimwe nzvimbo.
Aluminium hydroxide imhando yekuzadza isingasanganisike inodzivisa moto, kuti iwane mhedzisiro iri nani yekudzivisa moto, huwandu hwekuzadza hunofanirwa kupfuura 40% (huwandu hwese), humwe hwakakwira kusvika 60%, asi huwandu hwekuzadza hwakawanda hahungokanganisi zvakanyanya hunhu hwemuchina hwezvigadzirwa, asiwo hunoita kuti kubuda uye mashandiro ekugadzirisa zvinyanye kuipa.
Saka, kuti aruminiyamu hydroxide iite zvakanaka kwazvo, inogona kushandiswa zvakanyanya muzvinhu zvinodzora moto zvakaita sepolyolefin, inofanira kugadziriswa nealuminium hydroxide powder pamusoro, kuitira kuvandudza hunyanzvi hwemuviri nemakemikari pamusoro, kuwedzera super-fine aruminiyamu hydroxide powder uye substrate, organic polymer kana resin inoenderana uye kupararira kwayo mu organic substrate, kuitira kuvandudza simba remuchina wezvinhu uye kushanda kwayo kwakazara.
1. Chinogadzirisa pamusoro chinowanzo shandiswa pakugadzira aluminium hydroxide yakawanda
(1) mumiririri wekubatanidza silane
Kune marudzi anopfuura zana ezvishandiso zvekubatanidza silane, pakati pazvo chishandiso chekubatanidza silane cheboka rimwe chete ndicho chakasimba zvikuru. Kugadzikana kwechishandiso chekubatanidza silane cheboka chinoshanda chiri pakati pesimbi nesimbi. Pamusoro pekusimudzira hunhu hwemakanika hwezvigadzirwa, chishandiso chekubatanidza silane cheboka chinoshanda chinogonawo kuvandudza hunhu hwemagetsi uye kuramba hunyoro hwezvigadzirwa.
(2) mumiriri wekubatanidza zirconium
Kirasi yekubatanidza zirconium ine zirconium aluminate yakaderera molecule mass ye inorganic polymer muketani huru yemorekuru pamusoro pekuumbwa kwemhando mbiri dze organic ligand subunits, dentate ine coupling agent yakanaka hydroxyl kugadzikana, imwe dentate kune coupling agent yakanaka organic reactions, iyo aluminium hydroxide superfine aluminum hydroxide powder ine mhedzisiro yakanaka yakagadziriswa.
(3) mafuta akawanda nemunyu wawo
Muchimiro chemamorekuru emafatty acids akakwira nemunyu wawo, mugumo mumwe iboka realkyl refu, uye mumwe mugumo iboka recarboxyl nemunyu wayo wesimbi unogona kusangana nemapoka anoshanda ealuminium hydroxide pamusoro. Kurapa upfu hwealuminium hydroxide hwakanyanya nemafuta akawanda nemunyu wayo kunogona kuvandudza hukama huripo pakati peupfu hwealuminium hydroxide hwakanyanya nepolymer molecule, uye kuvandudza mashandiro emuchina uye ekugadzirisa chigadzirwa.
(4) maasidhi eorganic asina kuguta
Maasidhi asingasarudzwe eorganic anowanzo shandiswa ndeanoti: acrylic acid, methacrylic acid, cinnamic acid, nezvimwewo. Kazhinji, kana acid yakasimba, ndipo panobva paita ionic bond iri nyore kuumba, saka sarudza yakawanda: acrylic acid uye methacrylic acid.
Asidhi dzakasiyana-siyana dzeorganic dzinogona kushandiswa dzoga, dzinogona kushandiswawo zvakasanganiswa, kurapwa kwealkali metal ions dzine mineral ultrafine aruminiyamu hydroxide powder, mhedzisiro yacho iri nani.
(5) organosilicon
Macromolecule organosilicon, inozivikanwawo semafuta esilicon, imhando yepolymer yakabatana neboka reorganic paatomu yesilicon nesilicon oxygen bond chain (si-o-si) seskeleton. Inonyanya kushandiswa ihydrogen-containing polymethylsiloxane, hydroxyl-terminated polydimethylsiloxane, nezvimwewo.
2. Maitiro ekugadzirisa pamusoro pe ultra-fine aruminiyamu hydroxide
Parizvino, nzira dzekugadzirisa pamusoro peupfu hwe ultrafine aluminum hydroxide dzakanyanya kuoma uye kunyorova.
(1) kugadziriswa kwemvura yakaoma
Mukuita uku, upfu hwealuminium hydroxide hwakagadziriswa hunopiswa kusvika pakupisa kwakati, uye modifier inodonhedzwa zvishoma nezvishoma muupfu hwealuminium hydroxide hunokurumidza, uye chigadzirwa chinomiswa kuti chipakwe mushure mekusangana nenguva yakati.
Zvakanakira zvekugadzirisa zvinhu zvakaoma ndezvekuti michina haidiwi zvakanyanya uye mashandiro ari nyore. Dambudziko nderekuti vashandi vakawanda, uye mwero wekufukidza upfu hwealuminium hydroxide wakaderera.
(2) kugadziriswa kwemvura
Kugadziriswa kwemvura kunoitika mukugadzirwa kweupfu hwealuminium hydroxide hwakatsetseka, kugadzirwa kwealuminium hydroxide slurry mushure mekusefa, kusukwa, kusveta keke, mune imwe tembiricha yeslurry mushure mekuwedzera modifier, kusanganisa kwenguva yakati, kusefa, kuomesa uye kusveta packaging.
Zvakanakira zvekugadzirisa zvinhu zvakanyorova ndezvekuti simba rekushanda rakaderera, hapana kusvibiswa kweguruva, kushanda zvakanaka kwekugadzira zvinhu, mwero wekufukidza hupfu hwealuminium hydroxide, 20-30%, mhedzisiro yekushandura zvinhu yakakura uye yakagadzikana. Kana ichienzaniswa nekugadzirisa zvinhu zvakaoma, kugadzirisa zvinhu zvakanyorova kune maitiro akareba uye zvinodiwa zvakanyanya pamidziyo. Nekuda kwezvakanakira zvekugadzirisa zvinhu zvakanyorova, zviri kutsiva zvishoma nezvishoma nzira yekugadzira zvinhu zvakaoma.
3. Nzira yekuongorora yekuchinja pamusoro pemhedzisiro ye ultrafine aruminiyamu hydroxide
(1) bvunzo yekuyerwa kwemafuta
Mwero wekunyudzwa kwemafuta unonyanya kushandiswa kuyera huwandu hwemafuta emuorivhi anodiwa kana huwandu hwakati hweAl (OH) 3 huchingosvika pakuzara, uye hunoshandiswa kuyera huwandu hweresin hunodiwa kana huwandu hwakati hweAl (OH) 3 huchingosvika pakuzara.
Nzira yekuona nayo ndeiyi inotevera: upfu hwealumina hydroxide hwakatsetseka hunoyerwa uye sampuro yakaomeswa inosvika 10g, yoiswa mubeaker, yodonhedza castor oil neburette, yosanganiswa zvinyoro nyoro negirazi rod kuti mafuta ecastor oil uye sampuro yacho ipinde zvakaenzana mubhora. Huwandu hwemafuta ecastor anonyungudutswa pa100g yealuminium hydroxide hwakaverengerwa, kureva kuti, mwero wekunyudzwa kwemafuta eupfu hwealuminum hydroxide hwakatsetseka.
Mushure mekugadziriswa kweupfu hwealuminium hydroxide pamusoro, mwero wekunyudzwa kwemafuta uchachinja kusvika pamwero wakati. Kana upfu hwealuminium hydroxide hwakapfava hwakagadziriswa ne silane coupling agent, mwero wekunyudzwa kwemafuta uchaderera neinenge 10%.
(2) Bvunzo yeSEM
Maumbirwo eupfu hwe ultrafine aluminum hydroxide usati wachinja uye wachinja akaonekwa ne electron microscope. Kupararira kweupfu hwakagadziriswa mu matrix kwaive kuri nani pane kwechinhu chisina kuchinjwa.
(3) Kuedzwa kweFTIR
Fourier infrared spectroscopy (ftir) yakashandiswa kuongorora mapoka ari pamusoro pechigadzirwa. Semuenzaniso, huwandu hwevinyl - Vi na - Si hunogona kuonekwa ne ir spectra yealuminium hydroxide powder ne wet surface modification ye methyl vinyl silane.
(4) kusarudzwa kwehunhu hwechigadzirwa
Upfu hwealuminium hydroxide hwakagadziriswa uye husina kugadziriswa hwakashandiswa kuyedza ma "cable indexes" akadai se oxygen index, tensile strength uye length panguva yekudonha. Nekuenzanisa, zvinogona kuwanikwa kuti hunhu hwemoto hunodzora moto uye hwemakanika hwezvigadzirwa zvakagadziriswa hwavandudzwa.
(5) indekisi yekushanda
Activation index inhamba yekuongorora mhedzisiro yekuchinja kwemvura nekuyera huwandu hwearuminiyamu hydroxide inoyangarara pamusoro pemvura kusvika pahuwandu hwearuminiyamu hydroxide mushure mekugadzirisa. Nekuda kwemhando dzakasiyana dzekugadzirisa pamusoro uye nzira dzakasiyana dzekurapa dzeupfu hwearuminiyamu hydroxide hwakatsetseka, humwe hupfu hwakagadziriswa huchayangarara pamusoro pemvura uye humwe huchanyura.
Zvakadai se sodium stearate, titanate wet modification, hydrophobic silane dry modification mushure me ultrafine aluminum hydroxide powder, activation index inogona kushandiswa kuongorora modification effect; Zvisinei, hydrophilic silane yakagadziriswa nenzira yakaoma, uye ultrafine aluminum hydroxide powder yakagadziriswa nenzira ye silane wet yaizonyura mumvura, saka modification effect yaisagona kuongororwa ne activation index, uye nzira chaiyo yekuongorora yaive infrared spectroscopy.
