I-China Mica Flakes Iguqula Umhlahlandlela Ophelele Wemboni Yenjoloba Wezimboni Ezisebenza Kakhulu kanye nabaphakeli

I-Mica Flakes Iguqula Imboni Yenjoloba Umhlahlandlela Ophelele Wabagcwalisi Abasebenza Kakhulu

Incazelo emfushane:

Ama-Mica flakes, anesakhiwo sawo esihlukile se-lamellar, ukuzinza kwamakhemikhali okumangalisayo, kanye nokuhambisana okuphawulekayo nama-matrices erabha, azimise ngokuqinile njengezigcwalisi ezisebenzayo eziphezulu embonini yerabha. Ngokungafani nezigcwalisi ezivamile ezifana ne-carbon black noma i-calcium carbonate, ama-mica flakes anikeza inhlanganisela eyingqayizivele yokuqinisa imishini, ukumelana nesimo sezulu, kanye nokuqina kobukhulu, okwenza kube ukukhetha okuhle kwemikhiqizo yerabha esebenza ezindaweni ezinzima, kufaka phakathi izivalo zezimoto, amapayipi erabha ezimboni, kanye namabhande okuhambisa.

Emkhakheni wezimbobo zerabha zezimoto, okuhlanganisa izimbobo zomnyango, izimbobo zamafasitela, kanye nama-gasket enjini, ama-mica flakes adlala indima ebalulekile ekukhuliseni ukumelana nokudabuka kanye nokusebenza kwesethi yokucindezela. Lezi zimbobo zibhekana nokucindezeleka okuvamile komshini, ukushintshashintsha kwezinga lokushisa okukhulu okusukela ku--40°C kuya ku-120°C, kanye nokuchayeka isikhathi eside emisebeni ye-UV, izinto ezingabangela ukuthi izimbobo zerabha ezivamile ziqhekeke, ziqine, noma zilahlekelwe ukunwebeka ngokuhamba kwesikhathi.

Ukwengezwa kwama-mica flakes angu-8%-15% we-high aspect ratio, anosayizi wezinhlayiya ezingu-30-80 μm kanye ne-aspect ratio engu-≥100, erabheni le-ethylene-propylene-diene monomer (EPDM) kuveza imiphumela emihle kakhulu. Amandla okudabuka kwerabha anda ngo-40%-60%, kuyilapho izinga lokucindezela, elilinganiswa ngemva kwamahora angu-70 ku-100°C, lehla kakhulu lisuka ku-35% laya ku-15%. Umkhiqizi wezingxenye zezimoto ohamba phambili eJalimane wenze izivivinyo eziningi esebenzisa ama-mica flakes ethu ezivalweni zeminyango ze-EPDM. Imiphumela yayimangalisa: ama-seal agcina ukuqina kwawo nokusebenza kwawo kokuvala imijikelezo yokuvula nokuvala engu-500,000, uma kuqhathaniswa nemijikelezo engu-300,000 kuphela yama-seal angenawo ama-mica flakes. Lokhu kuphila kwesikhathi eside kwenkonzo akugcini nje ngokunciphisa izindleko zokulungisa zabanikazi bezimoto kodwa futhi kuthuthukisa ukuthembeka okuphelele kwemikhiqizo yezimoto.

Kumapayipi enjoloba ezimboni asetshenziswa ekudlulisweni kwamakhemikhali, uwoyela, namanzi, ama-mica flakes ayasiza kakhulu ekuthuthukiseni ukumelana kwamakhemikhali kanye nokumelana nengcindezi. Lawa mapayipi avame ukuxhumana nemidiya egqwalisayo futhi kumele amelane nengcindezi ephezulu yangaphakathi efinyelela ku-10 MPa. Ama-mica flakes, anesakhiwo sawo se-lamellar esingangenwa amanzi, akha isithiyo esisebenzayo ngaphakathi kwe-matrix yenjoloba, enciphisa ukungena kwamakhemikhali ngo-50%-70%.

Uma engezwa kumapayipi enjoloba ye-nitrile (NBR) ngomthamo ongu-10%-20%, ama-mica flakes akhulisa kakhulu ingcindezi yokuqhuma kwepayipi ngo-25%-35% futhi andise impilo yayo yokusebenza ekusetshenzisweni kokudlulisa uwoyela kusukela onyakeni owodwa kuya eminyakeni emi-2-3. Isitshalo samakhemikhali eNetherlands sivivinye amapayipi ethu e-NBR aqiniswe yi-mica ekudlulisweni kwe-20% ye-sulfuric acid egxilile. Imiphumela yayiqinisekile: ngemuva kwezinyanga eziyi-12 zokusetshenziswa okuqhubekayo, amapayipi awazange abonise zimpawu zokuvuvukala noma ukuvuza, kanti amapayipi e-NBR ajwayelekile ahluleka ngemva kwezinyanga ezi-4 kuphela. Ngaphezu kwalokho, ama-mica flakes athuthukisa ukuzinza kobukhulu bamapayipi enjoloba, anciphisa ukushwabana ngesikhathi sokuhlanganiswa kwe-vulcanization ngo-15%-25% futhi aqinisekise ukulingana okunembile nezixhumi.

Zonke izinhlayiya zethu ze-mica zihlangabezana nezindinganiso eziqinile zemboni ngokwezinkomba zobuchwepheshe ezibalulekile. Okuqukethwe komswakama kungu-≤0.3%, okuqukethwe komlotha kungu-0.5%, ukumuncwa kwamafutha kungu-≤25 mL/100g, futhi zibonisa ukumelana okuhle kakhulu nokushisa, zihlala zizinzile emazingeni okushisa afinyelela ku-600°C. Ngaphezu kwalokho, imikhiqizo yethu ihambisana ngokugcwele nemithethonqubo ye-RoHS kanye ne-REACH, ngokuqukethwe kwensimbi esindayo kungaphansi kakhulu kwemingcele yokuphepha yomhlaba wonke (i-lead ingu-0.0005%, i-arsenic ingu-0.0003%).

Uma kukhulunywa ngezokuthutha, sibeka phambili ikhwalithi nobuqotho bemikhiqizo yethu. Ama-mica flakes ethu apakishwe ezikhwameni ezingangeni umswakama (25 kg/isikhwama), anefilimu yangaphakathi ye-polyethylene kanye nesikhwama sephepha sangaphandle se-kraft ukuvimbela ukumuncwa komswakama ngesikhathi sokuthuthwa olwandle. Sesisungule ubudlelwano obuqinile nezinkampani ezihamba phambili zokuthumela njengeMaersk kanye ne-COSCO, siqinisekisa ukulethwa ngesikhathi kumakhasimende eYurophu, eNyakatho Melika, naseNingizimu-mpumalanga ye-Asia zingakapheli izinsuku ezingu-15-30.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

I-Mica yigama elijwayelekile lamaminerali eqembu le-mica. Iyi-aluminosilicate ye-potassium, i-aluminium, i-magnesium, i-iron, i-lithium nezinye izinsimbi, zonke ezibekwe ngezingqimba futhi zi-monoclinic. I-crystal iyi-pseudohexagonal lamellae noma efana ne-plate, ngezinye izikhathi i-columnar. Ukuqhekeka kwe-lamellar kuphelele kakhulu, kune-glass luster kanye ne-elastic sheet. Inkomba yokubuyisa ye-mica iyanda ngokwanda kokuqukethwe kwensimbi, kusukela ekuveleni okuphansi kuya ekuveleni okuphakathi. Uhlobo olungenayo insimbi alunambala ku-flake. Uma okuqukethwe kwensimbi kuphakeme, kulapho umbala uba mnyama khona, futhi kuba ne-polychromatic futhi kuncela kakhulu.

Usayizi we-Mica flake: 6-10mesh, 10-20mesh,
Impuphu ye-Mica: 200mesh, 325mesh, 600mesh, 800mesh, 1250mesh, 2000mesh, 3000mesh kanye ne-5000mesh.

Isicelo
Embonini, i-biotite isebenzisa kakhulu ukuvikela kwayo ukushisa, kanye nokumelana ne-asidi, ukumelana ne-alkali, ukumelana nokucindezelwa kanye nokumelana nokuxebuka, njengezinto zokuvikela imishini kagesi kanye nemishini kagesi; okwesibili, isetshenziselwa ukukhiqiza amafasitela nezingxenye zemishini zama-steam boilers kanye nezitofu zokuncibilikisa. Ama-Mica chips kanye ne-mica powder kungacutshungulwa kube yiphepha le-mica, futhi kungaphinde kuthathe indawo yeshidi le-mica ukuze kukhiqizwe izinto ezahlukahlukene zokuvikela ukushisa ezingabizi kakhulu nezifanayo.

I-Muscovite isetshenziswa kakhulu embonini, ilandelwe yi-phhlogopite. Isetshenziswa kabanzi embonini yezinto zokwakha, embonini yokulwa nomlilo, i-ejenti yokucima umlilo, induku yokushisela, ipulasitiki, ukufakelwa kukagesi, ukwenza iphepha, iphepha le-asphalt, irabha, i-pigment ye-pearlescent kanye neminye imboni yamakhemikhali.

Impuphu ye-mica ethambile kakhulu isetshenziswa njengesigcwalisi esisebenzayo sepulasitiki, upende, upende, irabha njalo njalo, okungathuthukisa amandla ayo okusebenza, kuthuthukise ukuqina, ukunamathela, ukumelana nokuguga kanye nokumelana nokugqwala.
