Barium sulfate chinhu chakakosha chemakemikari asina kugadzirwa chinogadzirwa kubva muhari yebarite. Haingori chete nekushanda kwakanaka kwemaziso uye kugadzikana kwemakemikari, asiwo ine hunhu hwakakosha senge vhoriyamu, saizi yequantum uye mhedzisiro yeinterface. Saka, inoshandiswa zvakanyanya mukuputira, mapurasitiki, bepa, rabha, inki nepigment nedzimwe nzvimbo. Nanometer barium sulfate ine zvakanakira zvenzvimbo yepamusoro chaiyo, kushanda kwakanyanya, kupararira kwakanaka, nezvimwewo. Inogona kuratidza kushanda kwakanaka kana ikashandiswa pazvinhu zvakasanganiswa. HCMilling (Guilin Hongcheng) inyanzvi yekugadzirabaritechigayo chekukuyamichina Yedu.baritechitenderedza chakamirachigayo Muchina unogona kukuya upfu hwebarite hwe80-3000 mesh. Izvi zvinotevera ndiwo manyuko ekushandisa nano barium sulfate.

1. Indasitiri yepurasitiki — mushure mekugadzirisa ne baritechigayo chekukuyamuchina

Kuwedzera nano barium sulfate yakagadziriswa nemuchina wekukuya webarite kupolymer kuti zvinhu zvakagadzirwa zvine simba guru uye kusimba kwave kuchikwezva kutariswa kwakawanda. Semuenzaniso, barium sulfate inogona kuwedzerwa ku polyethylene (PE), polypropylene (PP), polylactic acid (PLA), polytetrafluoroethylene (PTFE) nezvimwe zvinhu. Kunyanya, hunhu hwemuchina hwebarium sulfate hwakavandudzwa zvakanyanya mushure mekugadziriswa kwenzvimbo.

Kune akawanda ma polymer composites, nekuwedzera kwehuwandu hwe modifier, simba nekusimba kwezvinhu zvakagadzirwa zvinotanga kuwedzera uye zvobva zvadzikira. Izvi zvinodaro nekuti huwandu hwakawanda hwe modifier huchaita kuti multi-layer physical adsorption ive pamusoro pe nano barium sulfate, zvichikonzera agglomeration yakakura mu polymer, zvichikanganisa hunhu hwe mechanical hwezvinhu zvakagadzirwa, uye zvichiita kuti zviome kutamba hunhu hwakanaka hwe inorganic fillers; huwandu hushoma hwe modifier hunowedzera kukanganisa kwe interface pakati pe nano barium sulfate ne polymer, zvichikonzera kudzikira kwehunhu hwe mechanical hwe composite.

Pamusoro pehuwandu hwepamusoro hwemugadziri wepamusoro hune simba guru pahunhu hwemugadziri wemusanganiswa, huwandu hwebarium sulfate chinhu chakakoshawo. Izvi zvinodaro nekuti simba re nano barium sulfate rakakura kwazvo, iro rinogona kuita basa rekutakura kana rawedzerwa kumusanganiswa, nokudaro richigadzira simba rakati. Zvisinei, kana huwandu hwe nano barium sulfate hwakawandisa (hunopfuura 4%), nekuda kwekuungana kwayo mumusanganiswa uye kuwedzerwa kwezvikamu zvisingawanikwe, zvikanganiso zvematrix zvinowedzera, izvo zvinoita kuti musanganiswa uve nyore kutyoka, zvichiita kuti hunhu hwemugadziri wemusanganiswa huwedzere kuipa. Nokudaro, huwandu hwekuwedzera hwebarium sulfate hunofanira kunge huri mukati mehunhu hwayo hwakakodzera hwemuchina.

2. Indasitiri yekumonera — mushure mekugadzirisa nebaritechigayo chekukuyamuchina

Semhando yepigment, barium sulfate inoshandiswa zvakanyanya mukuputira uye inoita basa rakakosha mukuvandudza ukobvu, kuramba kwekukwesha, kuramba mvura, kuramba kupisa, kuomarara pamusoro uye kuramba kukanganiswa kwekuputira. Pamusoro pezvo, nekuda kwekusapinza kwayo mafuta uye kugona kwayo kuzadza, inogona kushandiswa mukuputira kwakavakirwa mumvura, maprimer, machira epakati uye machira emafuta kuderedza mutengo wekuputira. Inogona kutsiva 10% ~ 25% yetitanium dioxide mukuputira kwakavakirwa mumvura. Mhedzisiro yacho inoratidza kuti kuchena kuri nani uye simba rekuviga haridziki.

Hunhu hwe superfine barium sulfate yekuisa machira ndeiyi: 1) saizi yezvikamu zvakapfava uye kupararira kwezvikamu zvidiki; 2) Inoonekera kana ikaparadzirwa mumushonga we resin; 3) Kupararira kwakanaka muzvinhu zvepasi pekuisa machira; 4) Inogona kushandiswa senzira yekupararira pamwe chete ne organic pigment; 5) Inogona kuvandudza hunhu hwemuviri.

3. Indasitiri yepepa — mushure mekugadziriswa na baritechitenderedza chakamirachigayo muchina

Barium sulfate inowanzoshandiswa muindasitiri yekugadzira mapepa nekuda kwekugadzikana kwayo kwakanaka mumuviri nemakemikari, kuoma kwayo kuri pakati nepakati, kuchena kukuru, uye kupinza mwaranzi inokuvadza.

Semuenzaniso, bepa rekabhoni chinhu chinowanzo shandiswa pakudzidza uye muhofisi, asi pamusoro paro panogona kucheneswa ruvara, saka barium sulfate inodiwa kuti ive nemafuta akawanda, izvo zvinogona kuvandudza kupinza kweinki mubepa; Saizi yechinhu ichi idiki uye yakafanana, izvo zvinogona kuita kuti bepa rive rakati sandara uye zvichiita kuti muchina usanyanya kupfeka.

4. Indasitiri yefayibha yemakemikari — mushure mekugadzirwa na baritechitenderedza chakamirachigayo muchina

Fiber yeViscose, inozivikanwawo se "donje rekugadzira", yakafanana nefayibha yedonje yechisikigo, senge anti-static, kunyudzwa kwehunyoro kwakanaka, kudhayiwa nyore, uye kugadziriswa kwemachira nyore. Nano barium sulfate ine nano effect yakanaka. Nano barium sulfate/regenerated cellulose blend fiber yakagadzirwa kubva muzvinhu zviviri izvi imhando itsva yefayibha yecomposite, iyo inogona kuchengetedza hunhu hwakasiyana hwechikamu chimwe nechimwe. Uyezve, kuburikidza ne "kubatana" pakati pavo, inogona kutsiva zvikanganiso zvechinhu chimwe chete uye kuratidza hunhu hutsva hwezvinhu zvakasanganiswa.
