I-Mica Flakes iguqula iShishini leRubber Isikhokelo esipheleleyo sabaGcwalisi beMisebenzi ePhakamileyo

Inkcazo emfutshane:

Iiflakes zeMica, ezinesakhiwo sazo esahlukileyo selamellar, uzinzo olukhethekileyo lweekhemikhali, kunye nokuhambelana okumangalisayo neematrices zerabha, ziye zazibonakalisa njengezizalisi ezisebenzayo eziphezulu kushishino lwerabha. Ngokungafaniyo nezizalisi zemveli ezifana ne-carbon black okanye i-calcium carbonate, iiflakes ze-mica zibonelela ngomxube owahlukileyo wokuqinisa oomatshini, ukumelana nemozulu, kunye nozinzo olulinganayo, okwenza zibe lolona khetho lufanelekileyo kwiimveliso zerabha ezisebenza kwiindawo ezinzima, kubandakanya izitywino zeemoto, iipayipi zerabha zoshishino, kunye neebhanti zokuhambisa.

Kwicandelo lee-seal zerabha zeemoto, kuquka ii-seal zomnyango, ii-seal zeefestile, kunye nee-gasket ze-injini, ii-mica flakes zidlala indima ebalulekileyo ekuphuculeni ukumelana nokukrazula kunye nokusebenza kwe-compression set. Ezi seal ziphantsi koxinzelelo oluqhelekileyo loomatshini, ukuguquguquka okukhulu kobushushu ukusuka kwi--40°C ukuya kwi-120°C, kunye nokuvezwa ixesha elide kwi-UV radiation, izinto ezinokubangela ukuba ii-seal zerabha eziqhelekileyo ziqhekeke, ziqine, okanye zilahlekelwe bukuqina ngokuhamba kwexesha.

Ukongezwa kwe-8%-15% yee-high aspect ratio mica flakes, ezinobukhulu be-particle obuyi-30-80 μm kunye ne-aspect ratio ye-≥100, kwirabha ye-ethylene-propylene-diene monomer (EPDM) kuvelisa iziphumo ezimangalisayo. Amandla okukrazula kwerabha anda nge-40%-60%, ngelixa izinga loxinzelelo, elilinganiswa emva kweeyure ezingama-70 kwi-100°C, lehla kakhulu ukusuka kwi-35% ukuya kwi-15%. Umenzi wezinto zeemoto ophambili eJamani wenze uvavanyo olubanzi esebenzisa ii-mica flakes zethu kwii-EPDM door seals. Iziphumo bezimangalisa: ii-seals zigcine ukuthamba kwazo kunye nokusebenza kokutywina kangange-500,000 yokuvula nokuvala, xa kuthelekiswa ne-300,000 kuphela yee-seals ezingenazo ii-mica flakes. Olu bomi benkonzo bude alunciphisi nje iindleko zokugcinwa kwabanini bezithuthi kodwa lukwaphucula ukuthembeka ngokubanzi kweemveliso zeemoto.

Kwimibhobho yerabha yemizi-mveliso esetyenziswa ekudluliseleni iikhemikhali, ioyile, kunye namanzi, ii-mica flakes zibalulekile ekwandiseni ukumelana neekhemikhali kunye nokumelana noxinzelelo. Ezi hoses zihlala zidibana ne-corrosive media kwaye kufuneka zimelane noxinzelelo lwangaphakathi oluphezulu olufikelela kwi-10 MPa. Ii-mica flakes, kunye nolwakhiwo lwazo lwe-lamellar olungenakungena, zenza umqobo osebenzayo ngaphakathi kwi-matrix yerabha, zinciphisa ukungena kweekhemikhali nge-50%-70%.

Xa zongezwa kwiipayipi zerabha ze-nitrile (NBR) ngedosi ye-10%-20%, ii-mica flakes zonyusa kakhulu uxinzelelo oluqhumayo lwepayipi nge-25%-35% kwaye zandisa ubomi bayo benkonzo kwizicelo zokudlulisa ioyile ukusuka kunyaka omnye ukuya kwiminyaka emi-2-3. Isityalo seekhemikhali eNetherlands sivavanye iipayipi zethu ze-mica-reinforced NBR ekudlulisweni kwe-20% ye-sulfuric acid exineneyo. Iziphumo beziqinisekile: emva kweenyanga ezili-12 zokusetyenziswa rhoqo, iipayipi azizange zibonise zimpawu zokudumba okanye ukuvuza, ngelixa iipayipi ze-NBR eziqhelekileyo zingasebenzi emva kweenyanga ezi-4 kuphela. Ukongeza, ii-mica flakes ziphucula uzinzo olulinganayo lweepayipi zerabha, zinciphisa ukushwabana ngexesha lokuxuba nge-15%-25% kwaye ziqinisekisa ukulingana ngokuchanekileyo nezihlanganisi.

Zonke ii-mica flakes zethu zihlangabezana nemigangatho engqongqo yoshishino ngokweempawu eziphambili zobugcisa. Umxholo wokufuma yi-≤0.3%, umxholo wothuthu yi-≤0.5%, ukufunxwa kweoyile yi-≤25 mL/100g, kwaye zimelana kakuhle nobushushu, zihlala zizinzile kumaqondo obushushu afikelela kwi-600°C. Ngaphezu koko, iimveliso zethu zithobela ngokupheleleyo imigaqo ye-RoHS kunye ne-REACH, kunye nomxholo wesinyithi esinzima ongaphantsi kakhulu kwimida yokhuseleko lwehlabathi (i-lead yi-≤0.0005%, i-arsenic yi-≤0.0003%).

Xa kufikwa kwimicimbi yezothutho, sibeka phambili umgangatho kunye nokuthembeka kweemveliso zethu. Iiflakes zethu ze-mica zipakishwe kwiingxowa ezingangenisi manzi (25 kg/ibhegi), ezinefilimu yangaphakathi ye-polyethylene kunye nebhegi yangaphandle yephepha le-kraft ukuthintela ukufunxwa komswakama ngexesha lokuthuthwa elwandle. Siye saseka ubudlelwane obuqinileyo neenkampani eziphambili zokuhambisa imikhumbi ezifana neMaersk kunye neCOSCO, siqinisekisa ukuhanjiswa ngexesha elifanelekileyo kubathengi eYurophu, eMntla Melika, nakuMzantsi-mpuma we-Asia kwiintsuku ezili-15-30.

Iinkcukacha zeMveliso

Iithegi zeMveliso

I-Mica ligama eliqhelekileyo leeminerali zeqela le-mica. Yi-aluminosilicate ye-potassium, i-aluminium, i-magnesium, i-iron, i-lithium kunye nezinye iimetali, zonke ezibekwe ngokwee-layers kwaye zi-monoclinic. I-crystal ifana ne-pseudohexagonal lamellae okanye i-plate efana ne-pseudohexagonal, ngamanye amaxesha i-columnar. I-lamellar cleavage igqibelele kakhulu, ine-glass luster kunye ne-elastic sheet. I-refractive index ye-mica iyanda ngokunyuka komxholo we-iron, ukusuka kwi-protrusion ephantsi ukuya kwi-protrusion ephakathi. Uhlobo olungenayo i-iron alunambala kwi-flake. Okukhona umxholo we-iron uphezulu, kokukhona umbala umnyama, kwaye kokukhona i-polychromatic kunye ne-absorptive.

Ubungakanani be-Mica flake: 6-10mesh, 10-20mesh,
Umgubo weMica: 200mesh, 325mesh, 600mesh, 800mesh, 1250mesh, 2000mesh, 3000mesh kunye ne-5000mesh.

Isicelo
Kwishishini, i-biotite isebenzisa kakhulu i-insulation yayo kunye nokumelana nobushushu, kunye nokumelana ne-asidi, ukumelana ne-alkali, ukumelana nokucinezelwa kunye nokumelana nokuxobuka, njengezinto zokuthintela izixhobo zombane kunye nezixhobo zombane; okwesibini, isetyenziselwa ukuvelisa iifestile kunye neendawo zoomatshini zeebhoyila zomphunga kunye nee-furniture zokunyibilikisa. Iitships ze-Mica kunye nomgubo we-mica zinokucutshungulwa zibe liphepha le-mica, kwaye zinokuthatha indawo yephepha le-mica ukuvelisa izinto ezahlukeneyo zokukhusela ezinobukhulu obuphantsi nezilinganayo.

IMuscovite yeyona isetyenziswa kakhulu kushishino, ilandelwa yi-phhlogopite. Isetyenziswa kakhulu kushishino lwezixhobo zokwakha, kushishino lokucima umlilo, kwiarhente yokucima umlilo, kwintonga yokuwelda, kwiplastiki, ekugqumeni umbane, ekwenzeni iphepha, kwiphepha le-asphalt, kwirabha, kwi-pigment ye-pearlescent nakwezinye iikhemikhali.

Umgubo we-mica ocoliweyo kakhulu usetyenziswa njengesizalisi esisebenzayo kwiplastiki, ipeyinti, ipeyinti, irabha njalo njalo, nto leyo enokuphucula amandla ayo oomatshini, yonyuse ukuqina, ukunamathela, ukulwa nokwaluphala kunye nokumelana nokugqwala.
