Hollow glass microspheres igirazi microspheres ine yakaderera density, huremu huremu uye yakakwirira simba. Nekuda kwehunhu hwakakomba, zvichienzaniswa neakajairwa magirazi mabhedhi, ine hunhu hwehuremu huremu, kuderera kwehuremu uye kuita kwakanaka kwekushisa kwekushisa. Nzira yacho yakawedzerwa zvakananga kune hurongwa hwekuputira, kuitira kuti firimu yekuputira inoumbwa nekuporeswa kwechifukidzo ine thermal insulation properties. Kuwedzera kune yakaderera kunyudzwa kwemafuta uye kushomeka kwehuwandu, kuwedzera 5% (wt) kunogona kuwedzera chigadzirwa chakapedzwa ne25% kusvika 35%, nekudaro kusawedzera kana kudzikisa mutengo weyuniti yejasi.
Hollow girazi microspheres yakavharwa mativi mativi, ayo anowedzerwa mukati mekuputira kuti aumbe akawanda microscopic akazvimirira ega ega ega ega ega, nekudaro anovandudza zvakanyanya kuvharirwa kweiyo firimu rekuputira kubva pakupisa uye ruzha uye kutamba basa rakanaka mukudzivirira kupisa uye kuderedza ruzha. Ita kuti iyo yekuputira iwedzere kusapinda mvura, anti-fouling uye anti-corrosion zvivakwa. Iyo makemikari inert pamusoro peiyo microbeads inoshingirira mukuora kwemakemikari. Kana iyo firimu inoumbwa, zvikamu zvegirazi microbeads yakanyatsorongeka kuti iite yakaderera porosity, kuitira kuti chifukidzo chepamusoro chigadzire firimu rinodzivirira rine simba rekuvhara pamvura uye ions inoparadza, iyo inoita basa rakanaka mukudzivirira. effect.
Iyo spherical chimiro chehollow magirazi mabhedhi anoita kuti ive yakanaka yekuparadzira mhedzisiro pane simba rekuita uye kushushikana. Kuiwedzera pakuputira kunogona kuvandudza kupikisa kweiyo bhaisikopo rekuvhara uye zvakare kunogona kuderedza kuwedzera kwekupisa uye kuputika kwejasi. yestress cracking.
Zvirinani kuchena uye shading maitiro. Iyo chena poda ine zvirinani kuchena mhedzisiro pane akajairwa pigments, zvinobudirira kuderedza huwandu hwemamwe anodhura mafirita uye pigment (ichienzaniswa netitanium dioxide, iyo vhoriyamu mutengo we microbeads ingori 1/5) Zvinobudirira kusimudzira kunamatira kwekunamira kwekutarisa. Iyo yakaderera mafuta yekunyudza maitiro egirazi microbeads inobvumira yakawanda resin kutora chikamu mukuumbwa kwefirimu, nekudaro ichiwedzera kunamatira kwekuputira ne3 kusvika ku4 nguva.
Kuwedzera 5% yemicrobeads kunogona kuita kuti kunyura kweawande kubva pa1.30 kusvika pazasi 1.0, nekudaro kudzikisa huremu hwekupotera zvakanyanya uye kudzivirira chiitiko chekuvhara madziro.
Microbeads ine yakanaka reflection mhedzisiro pamirayi ye ultraviolet, inodzivirira kuvhara kubva pakutsvuka uye kuchembera.
Iyo yakakwira yekunyungudika kweiyo microbead inovandudza zvakanyanya kupisa kwekushisa kwejasi uye inoita basa rakanaka kwazvo mukudzivirira moto. Iyo spherical particles ye microbeads inotamba basa remabheya, uye simba rekukwenya idiki, iro rinogona kuwedzera kuyerera kwekuvhara kwekuita kwejasi uye kuita kuti kuvaka kuve nyore.
Zvinokurudzirwa zvekushandisa: Huwandu hwekuwedzera huwandu i10% yehuremu hwese. Iwo ma microbeads anorapwa pamusoro uye ane yakaderera density, izvo zvinoita kuti iyo coating iwedzere kuwedzera viscosity uye kuyangarara panguva yekuchengetedza. Isu tinokurudzira kuwedzera iyo yekutanga viscosity yekupfeka (nekuwedzera iyo The yakawedzerwa huwandu hwehupfu hunodzora viscosity pamusoro pe140KU), muchiitiko ichi, chiitiko chinoyangarara hachizoitika nekuti viscosity yakanyanya kuderera, uye zvimedu zvechimwe nechimwe chinhu mu sisitimu inoderedzwa mukuita nekuda kweiyo yakakwira viscosity, iyo inobatsira kudzora viscosity. kugadzikana. Isu tinokurudzira nzira inotevera yekuwedzera: nekuti ma microbead ane akatetepa madziro madziro uye yakaderera shear kuramba, kuti ushandise zvizere maburi maitiro eiyo microbeads, zvinokurudzirwa kutora yekupedzisira nzira yekuwedzera, kureva, kuisa microbeads kuguma kweKuwedzera kunoparadzirwa nekukurudzira midziyo ine yakaderera kasi uye yakaderera shear simba zvakanyanya sezvinobvira. Nekuti denderedzwa rema microbeads ane fluidity yakanaka uye kupokana kuri pakati pawo hakuna kukura, zviri nyore kuparadzira. Inogona kunyoroveswa zvachose munguva pfupi, kungowedzera nguva yekukurudzira kuti uwane kupararira kwakafanana.
Microbeads ikemikari inert uye haina chepfu. Nekudaro, nekuda kwehuremu hwayo hwakareruka, kutarisirwa kwakakosha kunodiwa pakuiwedzera. Isu tinokurudzira nhanho-ne-nhanho nzira yekuwedzera, ndiko kuti, huwandu hwechimwe nechimwe chekuwedzera ndeye 1/2 yeasara mamicrobeads, uye zvishoma nezvishoma akawedzera, izvo zvinogona kudzivirira zvirinani ma microbeads kuti asayangarara mumhepo uye kuita kuti kupararira kukwane.
