Umgubo weMicrospheres yoYilo olutsha lwaseTshayina ka-2021 weCement Slurries - IiMicrospheres zeglasi ezingenanto zokuzalisa ipeyinti – Kehui

Ii-microspheres zeglasi ezingenanto zi-microspheres zeglasi ezinobunzima obuphantsi, ubunzima obuphantsi kunye namandla aphezulu. Ngenxa yeempawu ezingenanto, xa kuthelekiswa nee-beads zeglasi eziqhelekileyo, ineempawu zobunzima obuphantsi, ubunzima obuphantsi kunye nokusebenza kakuhle kobushushu. Le ndlela yongezwa ngokuthe ngqo kwinkqubo yokubopha, ukuze ifilimu yokubopha eyenziwe ngokucocwa kwengubo ibe neepropati zobushushu. Ukongeza ekufunxeni kwayo i-oyile ephantsi kunye nobunzima obuphantsi, ukongeza i-5% (wt) kunokunyusa imveliso egqityiweyo ngama-25% ukuya kuma-35%, ngaloo ndlela kunganyusi okanye kunciphise ixabiso leyunithi yobungakanani bengubo.
Iimicrospheres zeglasi ezingenanto ziindawo ezivaliweyo ezingenanto, ezongezwa kwi-coating ukuze zenze ii-microscopic independent thermal insulation cavities ezininzi, ngaloo ndlela ziphucula kakhulu i-insulation yefilimu ye-coating nxamnye nobushushu nesandi kwaye zidlala indima entle eku-insulation yobushushu kunye ne-ingxolo. Yenza i-coating ibe ne-waterproof engaphezulu, i-anti-fruiting kunye ne-anti-corrosion properties. Umphezulu we-microbeads ongenazikhemikhali uyamelana ne-corrosion yekhemikhali. Xa ifilimu yenziwe, amasuntswana e- iiglasi ezincinci Zilungelelaniswe ngokusondeleyo ukuze zenze i-porosity ephantsi, ukuze umphezulu wogquma wenze ifilimu ekhuselayo enefuthe lokuthintela ukufuma kunye nee-ion ezirhabaxa, ezidlala indima entle ekukhuseleni.

Ulwakhiwo olungqukuva lweentsimbi zeglasi ezingenanto luyenza ibe nefuthe elihle lokusasazeka kumandla okuchaphazeleka kunye noxinzelelo. Ukuyifaka kwingubo kunokuphucula ukumelana nokuchaphazeleka kwefilimu yokugquma kwaye kunokunciphisa ukwanda kobushushu kunye nokuqhekeka kwengubo.

Isiphumo esingcono sokuba mhlophe kunye nomthunzi. Umgubo omhlophe unesiphumo esingcono sokuba mhlophe kuneepigment eziqhelekileyo, nto leyo enciphisa ngempumelelo inani lezinye izizalisi kunye neepigment ezibizayo (xa kuthelekiswa ne-titanium dioxide, ixabiso lomthamo wee-microbeads limalunga ne-1/5 kuphela) Iphucula ngokufanelekileyo ukunamathela kwengqwalasela yokugquma. Iimpawu eziphantsi zokufunxa ioyile zee-microbeads zeglasi zivumela i-resin engaphezulu ukuba ithathe inxaxheba ekwakhiweni kwefilimu, ngaloo ndlela inyusa ukunamathela kwengubo ngokuphindwe kathathu ukuya kane.

Ukongeza i-5% yee-microbeads kunokwenza uxinano lwe-coating ukusuka kwi-1.30 ukuya ngaphantsi kwe-1.0, ngaloo ndlela kunciphisa kakhulu ubunzima be-coating kwaye kuthintelwe ukuba i-coating yodonga ikhubeke.

Ii-microbeads zinefuthe elihle lokubonakalisa kwimitha ye-ultraviolet, zithintela ulusu ukuba lungaphuphuki kwaye lungagugi.

Iqondo eliphezulu lokunyibilika kwee-microbeads liphucula kakhulu ukumelana nobushushu bengubo kwaye lidlala indima entle kakhulu ekuthinteleni umlilo. Amasuntswana angqukuva ee-microbeads adlala indima yeebheringi, kwaye amandla okungqubana mancinci, nto leyo enokuphucula ukusebenza kwengubo yokuhambahamba kwaye yenze ulwakhiwo lube lula ngakumbi.

Iingcebiso zokusetyenziswa: Isixa esiqhelekileyo sokongeza yi-10% yobunzima obupheleleyo. Ii-microbeads zilungiswa phezu komhlaba kwaye zinobunzima obuphantsi, nto leyo eyenza ukuba i-coating ithambekele ekwandeni kwe-viscosity kunye ne-float ngexesha lokugcina. Sicebisa ukwandisa i-viscosity yokuqala ye-coating (ngokwandisa i-viscosity engaphezulu kwe-140KU), kule meko, into edadayo ayiyi kwenzeka kuba i-viscosity iphantsi kakhulu, kwaye amasuntswana ento nganye kwinkqubo ancitshiswa ngumsebenzi ngenxa ye-viscosity ephezulu, eluncedo ekulawuleni i-viscosity. Sicebisa kakhulu le ndlela ilandelayo yokongeza: kuba ii-microbeads zinodonga oluncinci lwe-particle kunye nokumelana okuphantsi kwe-shear, ukuze kusetyenziswe ngokupheleleyo iimpawu ezingenanto ze-microbeads, kucetyiswa ukuba kuthathwe indlela yokugqibela yokongeza, oko kukuthi, beka ii-microbeads ekupheleni kwe-. Ukongeza kusasazeka ngezixhobo zokuxubha ngesantya esiphantsi kunye namandla aphantsi e-shear kangangoko kunokwenzeka. Ngenxa yokuba imo ye-spherical yee-microbeads inokuguquguquka okuhle kwaye ukungqubana phakathi kwazo akukukhulu, kulula ukusasazeka. Ingafunxwa ngokupheleleyo ngexesha elifutshane, yongeza ixesha lokuxukuxa ukuze isasazeke ngokulinganayo.

Ii-microbeads azinazo iikhemikhali kwaye azinabungozi. Nangona kunjalo, ngenxa yobunzima bazo obulula kakhulu, kufuneka unonophelo olukhethekileyo xa zifakwa. Sicebisa indlela yokongeza inyathelo ngenyathelo, oko kukuthi, ubungakanani bokongeza ngakunye yi-1/2 yee-microbeads eziseleyo, kwaye zongezwe kancinci kancinci, nto leyo enokuthintela ngcono ii-microbeads ukuba zingadada emoyeni kwaye zenze ukusasazeka kwazo kuphelele.
