Isisombululo

I-Barium sulfate yinto ebalulekileyo yekhemikhali engafunekiyo ecutshungulwa kwi-barite raw ore. Ayinawo nje kuphela amandla okukhanya kunye nokuzinza kweekhemikhali, kodwa ikwanazo neempawu ezikhethekileyo ezifana nomthamo, ubungakanani be-quantum kunye nefuthe lojongano. Ke ngoko, isetyenziswa kakhulu kwiingubo, iiplastiki, iphepha, irabha, i-inki kunye ne-pigment kunye nezinye iindawo. I-Nanometer barium sulfate ineenzuzo zommandla othile ophezulu, umsebenzi ophezulu, ukusasazeka okuhle, njl. Ingabonisa ukusebenza okuhle kakhulu xa isetyenziswa kwizinto ezidityanisiweyo. I-HCMilling (Guilin Hongcheng) ngumvelisi ochwephesha wei-bariteumsi wokugayaoomatshini bethu.i-bariteirola ethe nkqoumsilo Umatshini ungagaya umgubo we-barite one-mesh engama-80-3000. Oku kulandelayo kukwazisa ngeendawo zokusetyenziswa kwe-nano barium sulfate.

1. Ishishini leplastiki — emva kokulungiswa nge i-bariteumsi wokugayaumatshini

Ukongeza i-nano barium sulfate ecutshungulwa ngumatshini wokugaya i-barite kwi-polymer ukuze kufunyanwe izinto ezidityanisiweyo ezinamandla aphezulu kunye nokuqina kuye kwatsala ingqalelo engakumbi. Umzekelo, i-barium sulfate ingongezwa kwi-polyethylene (PE), i-polypropylene (PP), i-polylactic acid (PLA), i-polytetrafluoroethylene (PTFE) kunye nezinye izinto. Ingakumbi, iipropati zoomatshini ze-barium sulfate ziphuculwe kakhulu emva kokuguqulwa komphezulu.

Kwinkoliso yee-polymer composites, ngokwanda kobuninzi be-modifier, amandla kunye nokuqina kwezinto ezidityanisiweyo kuya kunyuka kuqala kuze kunciphe. Oku kungenxa yokuba ubungakanani obugqithisileyo be-modifier buya kukhokelela kwi-multi-layer physical adsorption kumphezulu we-nano barium sulfate, nto leyo ebangela i-agglomeration enkulu kwi-polymer, echaphazela iipropati ze-mechanical zezinto ezidityanisiweyo, kwaye yenze kube nzima ukudlala iimpawu ezintle ze-inorganic fillers; Inani elincinci le-modifier liya kwandisa iziphene zomdibaniso phakathi kwe-nano barium sulfate kunye ne-polymer, nto leyo ebangela ukwehla kweempawu ze-mechanical ze-composite.

Ukongeza kwisixa esingentla se-surface modifier sinempembelelo enkulu kwiimpawu zoomatshini ze-composite, ubungakanani be-barium sulfate nabo buyinto ebalulekileyo. Oku kungenxa yokuba amandla e-nano barium sulfate makhulu kakhulu, anokudlala indima ekuthwaleni xa efakwa kwi-composite, ngaloo ndlela evelisa isiphumo esithile sokuqinisa. Nangona kunjalo, xa umxholo we-nano barium sulfate uphezulu kakhulu (ngaphezulu kwe-4%), ngenxa yokuhlangana kwayo kwi-composite kunye nokongezwa kwamasuntswana angaphiliyo, iziphene ze-matrix ziyanda, nto leyo eyenza i-composite ibe lula ukuqhekeka, ngaloo ndlela yenza iimpawu zoomatshini ze-composite zibe zimbi kakhulu. Ke ngoko, isixa esongeziweyo se-barium sulfate kufuneka sibe ngaphakathi kweempawu zayo zoomatshini ezifanelekileyo.

2. Ishishini lokugquma — emva kokucutshungulwa ngei-bariteumsi wokugayaumatshini

Njengohlobo lwe-pigment, i-barium sulfate isetyenziswa kakhulu kwiingubo kwaye idlala indima ebalulekileyo ekuphuculeni ubukhulu, ukumelana nokukruquka, ukumelana namanzi, ukumelana nobushushu, ubulukhuni bomphezulu kunye nokumelana nempembelelo kweengubo. Ukongeza, ngenxa yokufunxwa kwayo yioyile ephantsi kunye nomthamo ophezulu wokuzalisa, ingasetyenziswa kwiingubo ezisekelwe emanzini, ii-primers, iingubo eziphakathi kunye neengubo ezinamafutha ukunciphisa iindleko zeengubo. Ingathatha indawo ye-10% ~ 25% ye-titanium dioxide kwiingubo ezisekelwe emanzini. Iziphumo zibonisa ukuba ubumhlophe buphucukile kwaye amandla okufihla awancitshiswa.

Iimpawu ze-superfine barium sulfate kwiingubo zezi: 1) ubungakanani besuntswana obucolekileyo kakhulu kunye nokusasazwa kobukhulu besuntswana obuncinci; 2) Ibonakala ngokucacileyo xa isasazwa kwisisombululo se-resin; 3) Ukusasazeka kakuhle kwizinto ezisisiseko zokugquma; 4) Ingasetyenziswa njenge-arhente yokusasazeka xa idibene ne-pigment yendalo; 5) Ingaphucula iimpawu zomzimba.

3. Ishishini lephepha — emva kokuba lisetyenzisiwe i-bariteirola ethe nkqoumsilo umatshini

I-Barium sulfate isetyenziswa rhoqo kwishishini lokwenza iphepha ngenxa yozinzo lwayo oluhle ngokwasemzimbeni nangokweekhemikhali, ubulukhuni obuphakathi, ubumhlophe obukhulu, kunye nokufunxwa kwemisebe eyingozi.

Umzekelo, iphepha lekhabhoni lisetyenziswa kakhulu ekufundeni nasekusebenziseni izinto zaseofisini, kodwa umphezulu walo kulula ukuwutshintsha umbala, ngoko ke i-barium sulfate iyadingeka ukuze ibe nexabiso eliphezulu lokufunxa ioyile, nto leyo enokuphucula ukufunxa kwe-inki kwiphepha; Ubungakanani bamasuntswana buncinci kwaye buyafana, nto leyo enokwenza iphepha libe tyaba ngakumbi kwaye ibangele ukungonakali kancinci kumatshini.

4. Ishishini leefayibha zekhemikhali — emva kokucutshungulwa yi i-bariteirola ethe nkqoumsilo umatshini

I-Viscose fiber, eyaziwa ngokuba yi-"artificial cotton", ifana ne-cotton fiber yendalo kwindalo, efana ne-anti-static, ukufunxwa kakuhle komswakama, ukudaya lula, kunye nokucutshungulwa kwelaphu okulula. I-nano barium sulfate ine-nano effect entle. I-nano barium sulfate/regenerated cellulose blend fiber eyenziwe ngezi zinto zimbini njengezinto eziluhlaza luhlobo olutsha lwe-composite fiber, enokugcina iipropati ezizodwa zecandelo ngalinye. Ngaphezu koko, "ngokubambisana" phakathi kwazo, inokulungisa iintsilelo zezinto ezingenanto kwaye ibonise iipropati ezintsha zezinto ezidibeneyo.
