Barium sulfate ni igikoresho cy'ingenzi cya shimi kidakoreshwa mu bimera biva mu mabuye y'agaciro ya barite. Ntabwo ifite imikorere myiza y'urumuri no kudahindagurika kwa shimi gusa, ahubwo inafite imiterere yihariye nk'ingano, ingano ya quantum n'ingaruka zacyo. Kubwibyo, ikoreshwa cyane mu gusiga, plastiki, impapuro, rubber, wino na pigment n'ibindi. Nanometer barium sulfate ifite ibyiza byo kuba ubuso bwihariye, imikorere myinshi, gukwirakwira neza, nibindi. Ishobora kugaragaza imikorere myiza iyo ikoreshejwe ku bikoresho bivanze. HCMilling (Guilin Hongcheng) ni uruganda rw'umwuga rwabariteuruganda rusyaimashini. Zacubariteumuzenguruko uhagazeurusyo Imashini ishobora gusya ifu ya barite ifite mesh 80-3000. Ibi bikurikira ni intangiriro y'ikoreshwa rya nano barium sulfate.

1. Inganda za pulasitiki — nyuma yo gutunganywa hakoreshejwe bariteuruganda rusyaimashini

Kongeramo nano barium sulfate itunganywa n'imashini isya barite muri polymer kugira ngo haboneke ibikoresho bivanze bifite imbaraga nyinshi kandi bikomeye byakuruye abantu benshi. Urugero, barium sulfate ishobora kongerwa muri polyethylene (PE), polypropylene (PP), aside polylactic (PLA), polytetrafluoroethylene (PTFE) n'ibindi bikoresho. Cyane cyane, imiterere ya barium sulfate yarushijeho kuba myiza nyuma yo guhindura ubuso.

Ku bintu byinshi bya polymer, iyo ingano ya modifier yiyongereye, imbaraga n'ubukomere by'ibikoresho bya polymer byiyongera mbere hanyuma bikagabanuka. Ibi biterwa nuko ingano irenze urugero ya modifier izatuma habaho kwinjizwa kw'ibintu byinshi ku buso bwa nano barium sulfate, bigatera kwegerana gukomeye muri polymer, bigira ingaruka ku miterere y'ibikoresho bya polymer, kandi bigatuma bigorana gukina imiterere myiza y'ibikoresho bidafite umwimerere; ingano nto ya modifier yongera inenge hagati ya nano barium sulfate na polymer, bigatuma imiterere ya mashini ya composite igabanuka.

Uretse ingano yavuzwe haruguru y’ubuhinduzi bw’ubuso igira ingaruka zikomeye ku miterere y’ubuhanga bw’ibice bivanze, ingano ya barium sulfate nayo ni ikintu cy’ingenzi. Ibi biterwa nuko imbaraga za nano barium sulfate ari nini cyane, zishobora kugira uruhare mu gutuma ibintu birushaho kuba byiza iyo zongewe kuri ibyo bice bivanze, bityo bigatanga imbaraga runaka. Ariko, iyo ingano ya nano barium sulfate ari nyinshi cyane (irenga 4%), bitewe n’ubwinshi bwayo mu bice bivanze no kongeramo uduce tudafite umwimerere, inenge za matrix ziriyongera, bigatuma ibyo bice bivanze birushaho kuvunika, bityo bigatuma imiterere y’ibice bivanze iba mibi kurushaho. Kubwibyo, ingano y’inyongera ya barium sulfate igomba kuba iri mu miterere yayo ikwiye y’ubuhanga.

2. Inganda zikora irangi — nyuma yo gutunganya hakoreshejwebariteuruganda rusyaimashini

Nk'ubwoko bw'ibara, barium sulfate ikoreshwa cyane mu gusiga kandi igira uruhare runini mu kunoza ubunini, kudashwanyagurika, kudashwanyagurika kw'amazi, kudashwanyagurika k'ubushyuhe, kudashwanyagurika k'ubuso no kudashwanyagurika kw'udupira. Byongeye kandi, kubera ko ifite amavuta make kandi ikaba ifite ubushobozi bwo kuzuza, ishobora gukoreshwa mu gusiga amavuta, primers, intermediate coatings n'amavuta kugira ngo igabanye ikiguzi cy'udupira. Ishobora gusimbura 10% ~ 25% bya dioxyde ya titanium mu gusiga amavuta. Ibisubizo bigaragaza ko umweru urushaho kwiyongera kandi imbaraga zo guhisha ntizigabanuka.

Ibiranga barium sulfate nziza cyane ku bitwikirizo ni ibi bikurikira: 1) ingano nto cyane y'uduce duto n'ingano nto y'uduce; 2) Irabonerana iyo ijugunywe mu gisubizo cya resin; 3) Ishobora gukwirakwira neza mu bikoresho by'ibanze byo gutwikirizo; 4) Ishobora gukoreshwa nk'ikintu gikwirakwiza hamwe n'ibara ry'umwimerere; 5) Ishobora kunoza imiterere y'umubiri.

3. Inganda z'impapuro — nyuma yo gutunganywa na bariteumuzenguruko uhagazeurusyo imashini

Barium sulfate ikunze gukoreshwa mu nganda zikora impapuro kubera ko ihamye neza mu mubiri no mu binyabutabire, ubukana buri ku rugero, umweru mwinshi, no kwinjiza imirasire yangiza.

Urugero, impapuro za karuboni ni ibikoresho bisanzwe byo kwigiramo no mu biro, ariko ubuso bwazo bworoshye guhindura ibara, bityo barium sulfate irakenewe kugira ngo igire agaciro gakomeye ko kwinjiza amavuta, ibi bikaba bishobora kongera uburyo wino ifata impapuro; Ingano y'uduce ni nto kandi ni imwe, ibi bikaba bishobora gutuma impapuro zirushaho kuba ndende kandi bigatuma imashini idasaza cyane.

4. Inganda z'ibinyabutabire - nyuma yo gutunganywa na bariteumuzenguruko uhagazeurusyo imashini

Fibre ya Viscose, izwi kandi nka "ipamba y'ubukorano", isa n'ipamba karemano mu miterere yayo, nko kurwanya static, gufata neza ubushuhe, gusiga irangi byoroshye, no gutunganya imyenda byoroshye. Nano barium sulfate ifite ingaruka nziza za nano. Fibre ya nano barium sulfate/cellulose blend fibre ikozwe muri ibyo byombi nk'ibikoresho fatizo ni ubwoko bushya bwa fibre ivanze, ishobora kugumana imiterere yihariye ya buri gice. Byongeye kandi, binyuze mu "guhuza" hagati yabyo, ishobora gukosora inenge z'ibikoresho bimwe no kwerekana imiterere mishya y'ibikoresho bivanze.
