Iimicrosphere zeglasi ezingenanto ziimicrospheres zeglasi ezinoxinano oluphantsi, ubunzima obukhanyayo kunye namandla aphezulu. Ngenxa yeempawu ezingenanto, xa kuthelekiswa neentsimbi eziqhelekileyo zeglasi, ineempawu zobunzima bokukhanya, ubuninzi obuphantsi kunye nokusebenza kakuhle kwe-thermal insulation. Indlela yongezwa ngokuthe ngqo kwinkqubo yokugqoka, ukwenzela ukuba ifilimu yokugqoka eyenziwe ngokunyangwa kwengubo ineempawu zokushisa i-thermal. Ukongeza kwi-oyile ephantsi yokufunxa kunye noxinzelelo oluphantsi, ukongeza i-5% (wt) inokunyusa imveliso egqityiweyo nge-25% ukuya kwi-35%, ngaloo ndlela inganyuki okanye inciphise ixabiso lexabiso leyunithi yokugquma.
Iimicrosphere zeglasi eHollow zivaliwe zingqukuva, ezidityaniswe kwi-coating ukuze zenze imingxunya emininzi ezimeleyo yokugquma i-thermal, ngaloo ndlela iphucula kakhulu ukugqunyelelwa kwefilimu yokwambathisa ngokuchasene nobushushu kunye nesandi kwaye idlala indima entle ekugqumeni ubushushu kunye nokunciphisa ingxolo. Yenza i-coating ingabi namanzi ngakumbi, i-anti-fouling kunye ne-anti-corrosion properties. Umphezulu ongasebenziyo ngokwekhemikhali we-microbeads awuxhathisi kukonakala kweekhemikhali. Xa ifilimu yenziwe, iinqununu zeiglasi microbeads zicwangciswe ngokusondeleyo ukuze zenze i-porosity ephantsi, ukwenzela ukuba i-coating surface yenze ifilimu ekhuselayo enefuthe lokuthintela kumswakama kunye ne-ion e-corrosion, edlala indima enhle ekukhuseleni. isiphumo.
Ulwakhiwo olungqukuva lwamaso eglasi angenanto luyenza ibenesiphumo esihle sokusasazwa kumandla empembelelo kunye noxinzelelo. Ukuyongeza kwi-coating kunokuphucula ukuchasana kwempembelelo yefilimu yokugqoka kwaye kunokunciphisa ukwandiswa kwe-thermal kunye nokunciphisa i-coating. yokuqhekeka koxinzelelo.
Ubumhlophe obungcono kunye nefuthe le-shading. I-powder emhlophe inefuthe elimhlophe elingcono kunee-pigments eziqhelekileyo, ukunciphisa ngokufanelekileyo inani lezinye iifayili ezibiza kakhulu kunye ne-pigments (xa kuthelekiswa ne-titanium dioxide, ixabiso lexabiso le-microbeads limalunga ne-1/5 kuphela) Ukuphucula ngokufanelekileyo ukubambelela kokugxilwa kokugubungela. Iimpawu ze-oyile eziphantsi ze-microbeads zeglasi zivumela i-resin engaphezulu ukuba ithathe inxaxheba ekubunjweni kwefilimu, ngaloo ndlela ikhulise ukunamathela kwengubo ngama-3 ukuya kuma-4 amaxesha.
Ukongeza i-5% yemicrobeadsinokwenza ukuxinana kwe-coating ukusuka kwi-1.30 ukuya ngaphantsi kwe-1.0, ngaloo ndlela kuncitshiswe kakhulu ubunzima bokugquma kunye nokuphepha isenzeko sodonga lwe-coating.
I-Microbeads inefuthe elihle lokubonisa kwimisebe ye-ultraviolet, ukuthintela ukugquma kwe-yellowing kunye nokuguga.
Iqondo eliphezulu lokunyibilika kwe-microbeads liphucula kakhulu ukuchasana kweqondo lokushisa kwengubo kwaye lidlala indima enhle kakhulu ekukhuseleni umlilo. Iincinci ze-spherical ze-microbeads zidlala indima yeebheringi, kwaye i-friction force incinci, enokuthi iphucule ukusebenza kwe-coating ye-coating kunye nokwenza ukwakhiwa kube lula ngakumbi.
Izindululo zokusetyenziswa: Imali eyongeziweyo ngokubanzi yi-10% yobunzima bubonke. I-microbeads ziphathwe ngomphezulu kwaye zine-low density, eyenza i-coating ithande ukunyuka kwi-viscosity kwaye idada ngexesha lokugcina. Sincoma ukwandisa i-viscosity yokuqala yokugquma (ngokwandisa inani elongezelelweyo le-thickener lilawula i-viscosity ngaphezu kwe-140KU), kulo mzekelo, into edadayo ayiyi kwenzeka ngenxa yokuba i-viscosity iphantsi kakhulu, kunye namasuntswana ezinto eziphathekayo inkqubo iyancipha kumsebenzi ngenxa ye-viscosity ephezulu, enenzuzo yokulawula i-viscosity. uzinzo. Sicebisa ngamandla le ndlela yokongeza ilandelayo: ngenxa yokuba i-microbeads zineendonga ezinqabileyo ezinqabileyo kunye nokumelana okuphantsi kwe-chear, ukuze kusetyenziswe ngokupheleleyo iimpawu ezingenanto ze-microbeads, kuyacetyiswa ukuba kuthathwe indlela yokongeza okokugqibela, oko kukuthi, ukubeka i-microbeads kwindawo. ukuphela kwe Ukongezwa kuchithwa ngokuxhokonxa izixhobo ezinesantya esiphantsi kunye namandla okucheba aphantsi kangangoko kunokwenzeka. Ngenxa yokuba imilo engqukuva yee-microbeads inomanzi kwaye ingxabano phakathi kwazo ayinkulu, kulula ukuyichithachitha. Inokunyakanyiswa ngokupheleleyo ngexesha elifutshane, yongeza nje ixesha lokuvuselela ukufezekisa ukusasazwa okufanayo.
Ii-Microbeads zi-inert ngokwekhemikhali kwaye aziyiyo ityhefu. Nangona kunjalo, ngenxa yobunzima bayo obulula kakhulu, ukhathalelo olulodwa luyafuneka xa usongezwa. Sincoma indlela yokongeza inyathelo ngenyathelo, oko kukuthi, inani lokongezwa nganye yi-1/2 ye-microbeads eseleyo, kwaye yongezwa ngokuthe ngcembe, enokuthi ithintele ngcono i-microbeads ukuba idada emoyeni kwaye yenza ukusasazwa kugqibelele.
