Isixazululo

I-Barium sulfate iyinto ebalulekile yamakhemikhali angaphili ecutshungulwa kusuka ku-ore eluhlaza ye-barite. Ayigcini nje ngokuba nokusebenza okuhle kokukhanya kanye nokuqina kwamakhemikhali, kodwa futhi inezici ezikhethekile ezifana nomthamo, usayizi we-quantum kanye nomphumela wesixhumi. Ngakho-ke, isetshenziswa kabanzi ekumbozweni, epulasitikini, ephepheni, erabha, kuyinki kanye nombala nakwezinye izinkambu. I-Nanometer barium sulfate inezinzuzo zendawo ephezulu ethile, umsebenzi ophezulu, ukuhlakazeka okuhle, njll. Ingabonisa ukusebenza okuhle kakhulu uma isetshenziswa ezintweni ezihlanganisiwe. I-HCMilling (Guilin Hongcheng) ingumkhiqizi ochwepheshe wei-bariteumshini wokugayaimishini. Yethui-baritei-roller eqondileumshini wokugaya Umshini ungagaya i-80-3000 mesh barite powder. Okulandelayo isingeniso emasimini okusetshenziswa kwe-nano barium sulfate.

1. Imboni yepulasitiki — ngemva kokucutshungulwa i-bariteumshini wokugayaumshini

Ukwengeza i-nano barium sulfate ecutshungulwa umshini wokugaya we-barite ku-polymer ukuze kutholakale izinto ezihlanganisiwe ezinamandla aphezulu nokuqina kuye kwadonsela ukunaka okwengeziwe. Isibonelo, i-barium sulfate ingangezwa ku-polyethylene (PE), i-polypropylene (PP), i-polylactic acid (PLA), i-polytetrafluoroethylene (PTFE) nezinye izinto. Ikakhulukazi, izakhiwo zemishini ze-barium sulfate zithuthukiswe kakhulu ngemva kokuguqulwa kwendawo.

Kwabaningi abaxube i-polymer, ngokwanda kwenani le-modifier, amandla nokuqina kwezinto ezihlanganisiwe kuyanda kuqala bese kwehla. Lokhu kungenxa yokuthi inani eliningi le-modifier lizoholela ekufakweni kwezinto ezibonakalayo ezingqimbeni eziningi ebusweni be-nano barium sulfate, okubangela ukuhlangana okukhulu kwe-polymer, okuthinta izakhiwo zemishini zezinto ezihlanganisiwe, futhi kwenze kube nzima ukudlala izici ezinhle kakhulu zezigcwalisi ezingaphili; Inani elincane le-modifier lizokwandisa amaphutha okuxhumana phakathi kwe-nano barium sulfate ne-polymer, okuholela ekunciphiseni kwezakhiwo zemishini ze-composite.

Ngaphezu kwenani elingenhla lokushintsha indawo kunomthelela omkhulu ezimpahleni zemishini zenhlanganisela, inani le-barium sulfate nalo liyisici esibalulekile. Lokhu kungenxa yokuthi amandla e-nano barium sulfate makhulu kakhulu, angadlala indima ekuthwaleni uma engezwa kunhlanganisela, ngaleyo ndlela kukhiqize umphumela othile wokuqinisa. Kodwa-ke, lapho okuqukethwe kwe-nano barium sulfate kuphezulu kakhulu (ngaphezu kuka-4%), ngenxa yokuhlangana kwayo kunhlanganisela kanye nokwengezwa kwezinhlayiya ezingaphili, amaphutha e-matrix ayanda, okwenza inhlanganisela ibe sengozini yokuqhekeka, ngaleyo ndlela yenze izakhiwo zemishini zenhlanganisela zibe zimbi kakhulu. Ngakho-ke, inani lokwengeza le-barium sulfate kumele libe ngaphakathi kwezakhiwo zayo zemishini ezifanele.

2. Imboni yokumboza — ngemva kokucutshungulwai-bariteumshini wokugayaumshini

Njengohlobo lwe-pigment, i-barium sulfate isetshenziswa kabanzi ekumbozweni futhi idlala indima ebalulekile ekuthuthukiseni ukujiya, ukumelana nokuklwebheka, ukumelana namanzi, ukumelana nokushisa, ubulukhuni bomphezulu kanye nokumelana nomthelela wezimbozo. Ngaphezu kwalokho, ngenxa yokumuncwa kwayo okuphansi kwamafutha kanye nomthamo ophezulu wokugcwalisa, ingasetshenziswa ezimbozweni ezisekelwe emanzini, kuma-primer, ezimbozweni eziphakathi kanye nasezimbozweni ezinamafutha ukunciphisa izindleko zezimbozo. Ingathatha indawo ka-10% ~ 25% we-titanium dioxide ezimbozweni ezisekelwe emanzini. Imiphumela ikhombisa ukuthi ubumhlophe buyathuthuka futhi amandla okufihla awancishisiwe.

Izici ze-superfine barium sulfate zokumboza yilezi: 1) usayizi wezinhlayiya ezincane kakhulu kanye nokusatshalaliswa kosayizi wezinhlayiya ezincane; 2) Ibonakala kahle uma isakazwa kusisombululo se-resin; 3) Ukuhlakazeka okuhle ezintweni eziyisisekelo zokumboza; 4) Ingasetshenziswa njenge-ejenti yokuhlakaza ihlanganiswe nombala we-organic; 5) Ingathuthukisa izakhiwo zomzimba.

3. Imboni yephepha — ngemva kokucutshungulwa ngu i-baritei-roller eqondileumshini wokugaya umshini

I-Barium sulfate ivame ukusetshenziswa embonini yokwenza amaphepha ngenxa yokuqina kwayo okuhle ngokomzimba nangokwekhemikhali, ubulukhuni obuphakathi, ubumhlophe obukhulu, kanye nokumuncwa kwemisebe eyingozi.

Isibonelo, iphepha lekhabhoni liyinto evamile yokufunda kanye nezinto zasehhovisi, kodwa ubuso balo kulula ukubushintsha umbala, ngakho-ke i-barium sulfate iyadingeka ukuze ibe nenani eliphezulu lokumuncwa kwamafutha, okungathuthukisa ukumuncwa kweyinki kwephepha; Usayizi wezinhlayiya mncane futhi uyafana, okungenza iphepha libe yisicaba futhi kubangele ukuguguleka okuncane emshinini.

4. Imboni yefayibha yamakhemikhali — ngemva kokucutshungulwa ngu i-baritei-roller eqondileumshini wokugaya umshini

I-Viscose fiber, eyaziwa nangokuthi “ukotini wokwenziwa”, ifana ne-cotton fiber yemvelo ngokwemvelo, njengokulwa nokungaguquguquki, ukumuncwa kahle komswakama, ukudaya okulula, kanye nokucutshungulwa kwendwangu okulula. I-nano barium sulfate inomphumela omuhle we-nano. I-nano barium sulfate/i-cellulose blend fiber eyenziwe ngezinto ezimbili njengezinto zokusetshenziswa iwuhlobo olusha lwe-composite fiber, olungagcina izakhiwo ezihlukile zengxenye ngayinye. Ngaphezu kwalokho, “ngokubambisana” phakathi kwazo, ingalungisa ukushiyeka kwezinto ezilodwa futhi ibonise izakhiwo ezintsha zezinto ezihlanganisiwe.
