Isisombululo

I-Barium sulfate yimathiriyeli ebalulekileyo ye-inorganic chemical ekrwada esetyenzwa kwi-barite ore ekrwada.Ayinayo nje ukusebenza kakuhle kwe-optical kunye nokuzinza kweekhemikhali, kodwa ineempawu ezikhethekileyo ezifana nomthamo, ubungakanani be-quantum kunye ne-interface effect.Ngoko ke, isetyenziswa ngokubanzi kwiingubo, iiplastiki, iphepha, irabha, i-inki kunye ne-pigment kunye nezinye iindawo.I-Nanometer barium sulfate ineenzuzo zendawo ethile ephezulu, umsebenzi ophezulu, ukusabalalisa okulungileyo, njl.I-HCMilling(Guilin Hongcheng) ngumvelisi oqeqeshiweyo webariteilitye lokusilaoomatshini.Yethubariteumqengqeleki othe nkqoilitye lokusila umatshini unokusila i-80-3000 mesh barite powder.Oku kulandelayo kukwaziswa kwiinkalo zesicelo se-nano barium sulfate.

1. Ishishini lePlastiki - emva kokucubungula kunye bariteilitye lokusilaumatshini

Ukongeza i-nano barium sulfate ecutshungulwa ngumatshini wokusila we-barite kwi-polymer ukufumana izinto ezihlanganisiweyo ezinamandla aphezulu kunye nokuqina kuye kwatsala ingqalelo ngakumbi nangakumbi.Ngokomzekelo, i-barium sulfate inokongezwa kwi-polyethylene (PE), i-polypropylene (PP), i-polylactic acid (PLA), i-polytetrafluoroethylene (PTFE) kunye nezinye izinto.Ngokukodwa, iimpawu zomatshini ze-barium sulfate ziphuculwe kakhulu emva kokuguqulwa komhlaba.

Uninzi lwee-polymer composites, kunye nokunyuka kwexabiso le-modifier, amandla kunye nokuqina kwezixhobo ezidibeneyo zonyuka kuqala kwaye ziyancipha.Oku kungenxa yokuba isixa esigqithileyo sesilungisi siya kukhokelela kwi-adsorption ye-multi-layer ebonakalayo kumphezulu we-nano barium sulfate, nto leyo ebangela i-agglomeration enzulu kwipolymer, echaphazela iipropathi zoomatshini zemathiriyeli edibeneyo, kwaye yenze kube nzima ukudlala iimpawu ezibalaseleyo ze-polymer. izihluzi ze-inorganic;Umlinganiselo omncinci we-modifier uya kwandisa iziphene ze-interface phakathi kwe-nano barium sulfate kunye ne-polymer, okubangelwa ukuhla kweempawu zomatshini we-composite.

Ukongeza kwixabiso elingentla apha le-surface modifier inempembelelo enkulu kwiipropati zomatshini we-composite, inani le-barium sulfate liyinto ebalulekileyo.Oku kungenxa yokuba amandla e-nano barium sulfate inkulu kakhulu, enokuthi idlale indima ekuthwaleni xa ifakwe kwi-composite, ngaloo ndlela ivelise umphumo othile wokuqinisa.Nangona kunjalo, xa umxholo we-nano barium sulfate uphezulu kakhulu (ngaphezu kwe-4%), ngenxa ye-agglomeration yayo kwi-composite kunye nokongezwa kwamasuntswana e-inorganic, iziphene ze-matrix zanda, okwenza ukuba i-composite ikwazi ukuphuka, ngaloo ndlela yenza iimpawu zomatshini we-composite embi.Ngoko ke, inani elongezelelweyo le-barium sulfate kufuneka libe ngaphakathi kweempawu zayo ezifanelekileyo zomatshini.

2. Ishishini lokugquma - emva kokucubungula kunyebariteilitye lokusilaumatshini

Njengohlobo lwe-pigment, i-barium sulfate isetyenziswa ngokubanzi kwiingubo kwaye idlala indima ebalulekileyo ekuphuculeni ubukhulu, ukuxhatshazwa kwe-abrasion, ukuxhathisa kwamanzi, ukumelana nobushushu, ubunzima bomhlaba kunye nokuchasana kwempembelelo yeengubo.Ukongezelela, ngenxa yokutshatyalaliswa kweoli ephantsi kunye nomthamo ophezulu wokuzalisa, ingasetyenziselwa ukugubungela ngamanzi, ii-primers, iingqungquthela eziphakathi kunye neengubo ezinamafutha ukunciphisa iindleko zokugubungela.Ingathatha indawo ye-10% ~ 25% ye-titanium dioxide kwiingubo ezisekelwe emanzini.Iziphumo zibonisa ukuba ubumhlophe buphuculwe kwaye amandla okufihla awancitshiswa.

Iimpawu ze-superfine barium sulfate zokwaleka zezi: 1) ubungakanani obuhle kakhulu kunye nokusabalalisa ubungakanani be-particle;2) Icacile xa ihlakazwe kwisisombululo se-resin;3) I-dispersibility efanelekileyo kwizinto ezisisiseko zokugquma;4) Ingasetyenziselwa njenge-arhente yokusabalalisa ngokudibanisa ne-organic pigment;5) Inokuphucula iimpawu zomzimba.

3. Ishishini lephepha - emva kokulungiswa ngu bariteumqengqeleki othe nkqoilitye lokusila umatshini

I-Barium sulfate isoloko isetyenziswa kwishishini lokwenza iphepha ngenxa yokuzinza kwayo kakuhle ngokomzimba nangokwekhemikhali, ubulukhuni obuphakathi, ubumhlophe obukhulu, kunye nokufunxa imitha eyingozi.

Ngokomzekelo, iphepha lekhabhoni liyinto eqhelekileyo yokufunda kunye neofisi, kodwa ubuso bayo bulula ukuchithwa, ngoko ke i-barium sulfate iyadingeka ukuba ibe nexabiso eliphezulu lokufunxa ioli, elinokuphucula ukuxutywa kwe-inki yephepha;Ubungakanani be-particle buncinci kwaye bufanayo, obunokwenza iphepha libe licwecwe kwaye libangele ukugqoka okuncinci kumatshini.

4. Ishishini lemichiza yefayibha - emva kokulungiswa ngu bariteumqengqeleki othe nkqoilitye lokusila umatshini

Ifayibha yeViscose, ekwabizwa ngokuba “yi-cotton eyenziweyo”, iyafana nefayibha yomqhaphu yendalo ngokwendalo, efana ne-anti-static, ukufunxwa kakuhle kokufuma, ukudaya ngokulula, kunye nokusetyenzwa lula kwamalaphu.I-nano barium sulfate inefuthe elihle le-nano.I-nano barium sulfate / i-cellulose ehlaziyiweyo yokudibanisa i-fiber eyenziwe kwizinto ezimbini njengezinto eziluhlaza luhlobo olutsha lwefiber edibeneyo, enokugcina iimpawu ezizodwa zecandelo ngalinye.Ngaphezu koko, ngokusebenzisa "i-synergy" phakathi kwabo, inokwenza iintsilelo zento enye kwaye ibonise iimpawu ezintsha zezinto ezidibeneyo.
