Isixazululo

I-Barium sulfate iyi-inorganic chemical material eluhlaza ecutshungulwa ku-barite ore eluhlaza.Ayigcini nje ngokusebenza kahle kwe-optical kanye nokuzinza kwamakhemikhali, kodwa futhi inezici ezikhethekile ezifana nevolumu, usayizi we-quantum kanye nomphumela wokuxhumana.Ngakho-ke, isetshenziswa kabanzi kuma-coatings, amapulasitiki, amaphepha, irabha, uyinki nombala kanye neminye imikhakha.I-Nanometer barium sulfate inezinzuzo zendawo ethile ephezulu, umsebenzi ophezulu, ukuhlakazeka okuhle, njll. Ingabonisa ukusebenza okuhle kakhulu uma isetshenziselwa izinto ezihlanganisiwe.I-HCMilling(Guilin Hongcheng) ingumkhiqizi ochwepheshe webariteumshini wokugayaimishini.Eyethubaritei-roller eqondileisigayo umshini ungagaya i-80-3000 mesh barite powder.Okulandelayo yisingeniso emikhakheni yesicelo se-nano barium sulfate.

1. Imboni yePlastiki - ngemva kokucubungula nge bariteumshini wokugayaumshini

Ukwengeza i-nano barium sulfate ecutshungulwe umshini wokugaya i-barite ku-polymer ukuze kutholwe izinto eziyinhlanganisela ezinamandla nokuqina kudonse ukunakwa okwengeziwe.Isibonelo, i-barium sulfate ingafakwa ku-polyethylene (PE), i-polypropylene (PP), i-polylactic acid (PLA), i-polytetrafluoroethylene (PTFE) nezinye izinto.Ikakhulukazi, izakhiwo zemishini ye-barium sulfate ziye zathuthukiswa kakhulu ngemva kokuguqulwa kwendawo.

Ezinhlanganisela eziningi ze-polymer, ngokwanda kwenani lesilungisi, amandla kanye nokuqina kwezinto ezihlanganisiwe kuyanda kuqala bese kuncipha.Lokhu kungenxa yokuthi inani eleqile lesiguquli lizoholela ekukhangiseni okunezingqimba eziningi ebusweni be-nano barium sulfate, kubangele ukuhlangana okukhulu ku-polymer, kuthinte izakhiwo zemishini yezinto eziyinhlanganisela, futhi kwenze kube nzima ukudlala izici ezinhle kakhulu ze-polymer. ama-inorganic fillers;Inani elincane lesilungisi lizokwandisa amaphutha esixhumi esibonakalayo phakathi kwe-nano barium sulfate kanye ne-polymer, okuholela ekwehleni kwezakhiwo zemishini zenhlanganisela.

Ngaphezu kwenani elingenhla le-surface modifier linomthelela omkhulu ezintweni zemishini yenhlanganisela, inani le-barium sulfate nalo liyisici esibalulekile.Lokhu kungenxa yokuthi amandla e-nano barium sulfate makhulu kakhulu, angadlala indima ekuthwaleni lapho engezwa ku-composite, ngaleyo ndlela akhiqize umphumela othile wokuqinisa.Kodwa-ke, lapho okuqukethwe kwe-nano barium sulfate kuphezulu kakhulu (ngaphezu kuka-4%), ngenxa yokuhlanganiswa kwayo kuyinhlanganisela kanye nokwengezwa kwezinhlayiya ezingaphili, ukukhubazeka kwe-matrix kuyanda, okwenza inhlanganisela ijwayele ukuphuka, ngaleyo ndlela yenza izakhiwo mechanical of the composite sibi.Ngakho-ke, inani elingeziwe le-barium sulfate kufanele libe ngaphakathi kwezakhiwo zayo ezifanele zemishini.

2. Imboni yokugqoka - ngemva kokucubungula ngebariteumshini wokugayaumshini

Njengohlobo lwe-pigment, i-barium sulfate isetshenziswa kabanzi ekugqokeni futhi idlala indima ebalulekile ekuthuthukiseni ukushuba, ukumelana nokulimala, ukumelana namanzi, ukumelana nokushisa, ubulukhuni bobuso kanye nokumelana nomthelela wezingubo.Ukwengeza, ngenxa yokumuncwa kwayo okuphansi kwamafutha kanye nomthamo omkhulu wokugcwalisa, ingasetshenziswa emanzini asekelwe emanzini, ama-primers, ama-coating aphakathi nendawo kanye nama-oily coatings ukuze kuncishiswe izindleko zokugqoka.Ingangena esikhundleni se-10% ~ 25% ye-titanium dioxide ezimbotsheni ezisekelwe emanzini.Imiphumela ibonisa ukuthi ubumhlophe buyathuthukiswa futhi amandla okucasha awancishisiwe.

Izici ze-superfine barium sulfate zokumboza yilezi: 1) usayizi wezinhlayiyana ezinhle kakhulu kanye nokusabalalisa usayizi wezinhlayiyana ezincane;2) Isobala lapho ihlakazekile kusixazululo se-resin;3) I-dispersibility enhle ekuhlanganiseni okuyisisekelo;4) Ingasetshenziswa njenge-ejenti ehlakazayo ngokuhlanganiswa nombala wemvelo;5) Ingathuthukisa izakhiwo zomzimba.

3. Imboni yamaphepha - ngemva kokucubungula ngo baritei-roller eqondileisigayo umshini

I-Barium sulfate ivame ukusetshenziswa embonini yokwenza iphepha ngenxa yokusimama kwayo okuhle ngokomzimba namakhemikhali, ubulukhuni obusesilinganisweni, ubumhlophe obukhulu, nokumuncwa kwemisebe eyingozi.

Isibonelo, i-carbon paper iwukufunda okuvamile kanye nezinsiza zehhovisi, kodwa ubuso bayo bulula ukuchithwa, ngakho-ke i-barium sulfate iyadingeka ukuze ibe nenani eliphakeme lokumuncwa kwamafutha, elingathuthukisa ukumuncwa kwe-inki kwephepha;Usayizi wezinhlayiyana mncane futhi umfaniswano, ongenza iphepha libe flat futhi libangele ukuguga okuncane emshinini.

4. Chemical fiber industry - ngemva kokucubungula by baritei-roller eqondileisigayo umshini

I-Viscose fiber, eyaziwa nangokuthi “ukotini wokwenziwa”, ifana nefayibha kakotini yemvelo ngokwemvelo, njenge-anti-static, ukumuncwa kahle komswakama, ukudaya okulula, nokucubungula kwezindwangu kalula.I-nano barium sulfate inomphumela omuhle we-nano.I-nano barium sulfate/evuselelwe kabusha i-cellulose blend fiber eyenziwe kusuka kokubili njengezisetshenziswa zokusetshenziswa iwuhlobo olusha lwefiber ehlanganisiwe, engagcina izakhiwo eziyingqayizivele zengxenye ngayinye.Ngaphezu kwalokho, ngokusebenzisa "i-synergy" phakathi kwabo, ingakwazi ukubuyisela ukushiyeka kwento eyodwa futhi ibonise izakhiwo ezintsha zezinto ezihlanganisiwe.
