Kudzivirira kweChina Microsphere kwehunyanzvi - Magirazi madiki asina chinhu ekuzadza pendi - Kehui

Magirazi madiki madiki madiki egirazi ane huremu hushoma, huremu hushoma uye simba rakawanda. Nekuda kwehunhu hwayo hwemagirazi, kana ichienzaniswa nemagirazi akajairwa, ine hunhu hwehuremu hushoma, huremu hushoma uye kushanda zvakanaka kwekudzivirira kupisa. Nzira iyi inowedzerwa zvakananga kune system yekudzivirira, kuitira kuti firimu rekudzivirira rinoumbwa nekugadzika kwejira rive nehunhu hwekudzivirira kupisa. Pamusoro pekunyudzwa kwaro kwemafuta mashoma uye huremu hushoma, kuwedzera 5% (wt) kunogona kuwedzera chigadzirwa chakapedzwa ne25% kusvika 35%, nokudaro kusawedzera kana kutoderedza mutengo weyuniti yejira.
Magirazi madiki madiki madiki madiki, ayo anowedzerwa mujira rekudzivirira kuti agadzire makomba akawanda ekudzivirira kupisa akazvimirira, nokudaro zvichivandudza zvakanyanya kudzivirira kwefirimu rekudzivirira kupisa kubva pakupisa neruzha uye zvichiita basa rakanaka mukudzivirira kupisa nekuderedza ruzha. Ita kuti jasi rive risingapindi mvura, rinodzivirira kusvibiswa uye rinodzivirira ngura. Pamusoro pemajini madiki, ganda rinodzivirira ngura. Kana firimu raumbwa, zvidimbu zve magirazi madiki Zvakanyatsorongeka kuti zvigadzire porosity yakaderera, kuitira kuti pamusoro pechifukidziro paumbwe firimu rinodzivirira rine simba rekudzivirira hunyoro nemaayoni anoparadza, izvo zvinoita basa rakanaka mukudzivirira.

Maumbirwo egirazi rakatenderera anoita kuti rive nemhedzisiro yakanaka yekupararira kwesimba rekukanda uye kushushikana. Kuiisa pajira kunogona kuwedzera kusimba kwekukanda kwefirimu rekukanda uye kunogonawo kuderedza kuwedzera kwekupisa nekudzika kwejira rekukanda.

Kuchenesa uye kudzima zviri nani. Upfu huchena hune simba rekuchena kupfuura mavara akajairwa, zvichideredza huwandu hwezvimwe zvinozadza uye mavara anodhura (zvichienzaniswa netitanium dioxide, huwandu hwema microbeads hunongova 1/5 chete). Zvinowedzera kunamira kwe coating focus zvinobudirira. Hunhu hushoma hwekunwa mafuta hwe glass microbeads hunoita kuti resin yakawanda ikwanise kutora chikamu mukugadzirwa kwefirimu, nokudaro zvichiwedzera kunamira kwe coating nekatatu kusvika kana.

Kuwedzera 5% yema microbeads kunogona kuita kuti huwandu hwe coating huve kubva pa1.30 kusvika pasi pe1.0, zvichiita kuti huremu hwe coating huderere zvakanyanya uye kudzivirira chiitiko chekuti coating yemadziro inobviswa.

Ma microbeads ane simba rakanaka rekuratidza chiedza pamwaranzi ye ultraviolet, zvichidzivirira kuti chifukidziro chisatsvedzerere uye chisachembera.

Nzvimbo yakanyanya kunyunguduka yema microbeads inovandudza zvikuru kuramba kupisa kwe coatings uye inoita basa rakanaka mukudzivirira moto. Zvidimbu zve spherical zve microbeads zvinoita basa re bearing, uye simba rekukweshana diki, izvo zvinogona kuwedzera flow coatings ye coatings uye kuita kuti building ive nyore.

Zvinokurudzirwa pakushandisa: Huwandu hwekuwedzera huwandu i10% yehuremu hwese. Ma microbeads anogadziriswa pamusoro uye ane density yakaderera, izvo zvinoita kuti coating iwedzere viscosity uye ifambe panguva yekuchengetera. Tinokurudzira kuwedzera viscosity yekutanga ye coating (nekuwedzera huwandu hwe thickener hunodzora viscosity iri pamusoro pe140KU), muchiitiko ichi, chiitiko chekuyangarara hachizoitiki nekuti viscosity yakaderera, uye zvidimbu zvechinhu chimwe nechimwe mu system zvinodzikira mukushanda nekuda kwe viscosity yakakura, iyo inobatsira kudzora viscosity. Tinokurudzira zvakasimba nzira inotevera yekuwedzera: nekuti microbeads ine madziro matete uye resistance yakaderera ye shear, kuti ushandise zvizere hunhu hwema microbeads, zvinokurudzirwa kutora nzira yekupedzisira yekuwedzera, ndiko kuti, isa microbeads pakupera kwe. Kuwedzera kunoparadzirwa nekushandisa michina yekukurunga nekukurumidza kwakaderera uye simba shoma re shear zvakanyanya sezvinobvira. Nekuti chimiro che spherical che microbeads chine fluidity yakanaka uye kukweshana pakati pawo hakuna kukura, zviri nyore kupararira. Inogona kunyoroveswa zvachose munguva pfupi, ingowedzera nguva yekukurunga kuti ipararire zvakaenzana.

Ma microbeads haana makemikari uye haana chepfu. Zvisinei, nekuda kwehuremu hwawo hwakareruka, kungwarira kwakakosha kunodiwa pakuwedzera. Tinokurudzira nzira yekuwedzera nhanho nhanho, kureva kuti, huwandu hwekuwedzera kwega kwega ihafu ye microbeads dzasara, uye hunowedzera zvishoma nezvishoma, izvo zvinogona kudzivirira zviri nani microbeads kuti isayangarara mumhepo uye kuita kuti kupararira kwayo kuve kwakakwana.
