1. Ụlọ ọrụ plastik - mgbe nhazi ya na bariteigwe ihe igweigwe

Ịgbakwunye nano barium sulfate nke a na-edozi site na barite igwe igwe igwe na-egweri na polymer iji nweta ihe mgbagwoju anya na ike dị elu adọtala nlebara anya karịa.Dịka ọmụmaatụ, enwere ike ịgbakwunye barium sulfate na polyethylene (PE), polypropylene (PP), polylactic acid (PLA), polytetrafluoroethylene (PTFE) na ihe ndị ọzọ.Karịsịa, ihe eji arụ ọrụ nke barium sulfate emeziwanye nke ọma mgbe emezigharịrị elu.

Maka ọtụtụ ihe mejupụtara polymer, na mmụba nke ọnụọgụ mgbanwe, ike na ike nke ihe mejupụtara na-ebu ụzọ na-abawanye wee belata.Nke a bụ n'ihi na oke ego nke modifier ga-eduga na multi-layer anụ ahụ adsorption n'elu nano barium sulfate, na-eme ka oké agglomeration na polymer, na-emetụta n'ibu Njirimara nke mejupụtara ihe, na-eme ka o siri ike na-egwu magburu onwe àgwà nke. inorganic fillers;Obere obere ihe ngbanwe ga-eme ka ntụpọ interface dị n'etiti nano barium sulfate na polymer, na-ebute mbelata n'ime ihe eji arụ ọrụ nke ihe mejupụtara.

Na mgbakwunye na ọnụ ọgụgụ dị n'elu nke ngbanwe elu na-enwe mmetụta dị ukwuu na ihe eji arụ ọrụ nke ihe mejupụtara ya, ọnụọgụ barium sulfate bụkwa ihe dị mkpa.Nke a bụ n'ihi na ike nke nano barium sulfate dị nnọọ ukwuu, nke nwere ike ịrụ ọrụ na-ebu mgbe agbakwunyere na ihe mejupụtara, si otú a na-emepụta mmetụta na-ewusi ike.Otú ọ dị, mgbe ọdịnaya nke nano barium sulfate dị oke elu (karịa 4%), n'ihi na ọ na-eme ka ọ dịkwuo elu na ihe mejupụtara ya na mgbakwunye nke ihe ndị na-emepụta ihe na-emepụta ihe, ntụpọ matriks na-abawanye, nke na-eme ka ihe mgbagwoju anya na-agbaji, si otú ahụ na-eme ka ọkpụkpụ ahụ dịkwuo elu. n'ibu Njirimara nke mejupụtara njọ.Ya mere, ego mgbakwunye barium sulfate ga-abụrịrị n'ime akụrụngwa ya kwesịrị ekwesị.

2. Ụlọ ọrụ mkpuchi - mgbe nhazi ya nabariteigwe ihe igweigwe

Dị ka ụdị pigmenti, a na-eji barium sulfate eme ihe n'ọtụtụ ebe na mkpuchi ma na-arụ ọrụ dị mkpa n'ịkwalite ọkpụkpụ, nkwụsị nke abrasion, mmiri na-eguzogide mmiri, nguzogide okpomọkụ, ike elu na mmetụta nkwụsị nke mkpuchi.Tụkwasị na nke ahụ, n'ihi na ọ na-enweta mmanụ dị ala na ikike njuputa dị elu, enwere ike iji ya na mkpuchi mmiri, primers, mkpuchi etiti na mmanu mmanu iji belata ọnụ ahịa mkpuchi.Ọ nwere ike dochie 10% ~ 25% nke titanium dioxide na mkpuchi mmiri.Nsonaazụ na-egosi na a na-emeziwanye ọcha na ike ezoro ezo adịghị ebelata.

The e ji mara superfine barium sulfate maka coatings bụ: 1) nnọọ mma urughuru size na warara urughuru size nkesa;2) Ọ na-apụta ìhè mgbe a gbasasịrị na ngwọta resin;3) Ezi dispersibility na mkpuchi isi ihe;4) Enwere ike iji ya dị ka onye na-ekesa ihe na-ejikọta ya na pigmenti organic;5) Ọ nwere ike melite akụrụngwa anụ ahụ.

3. Ụlọ ọrụ akwụkwọ - mgbe nhazi site na bariterola kwụ ọtọigwe nri igwe

A na-ejikarị Barium sulfate eme ihe na ụlọ ọrụ na-emepụta akwụkwọ n'ihi ezigbo nkwụsi ike anụ ahụ na kemịkal ya, ike siri ike na-agafeghị oke, nnukwu ọcha, na ịmịnye ụzarị ọkụ.

Dịka ọmụmaatụ, akwụkwọ carbon bụ ihe mmụta na ụlọ ọrụ a na-ahụkarị, ma elu ya dị mfe ịmegharị agba, ya mere a chọrọ barium sulfate ka ọ nwee uru mmanụ dị elu, nke nwere ike imeziwanye ink absorption nke akwụkwọ ahụ;Ogo urughuru dị obere na otu, nke nwere ike ime ka akwụkwọ ahụ dịkwuo larịị ma mee ka ọ ghara ịdị na-eyi igwe.

4. Chemical eriri ụlọ ọrụ - mgbe nhazi site bariterola kwụ ọtọigwe nri igwe

Fibre Viscose, nke a makwaara dị ka "owu artificial", yiri eriri owu eke na okike, dị ka mgbochi static, nnabata mmiri dị mma, ịcha agba dị mfe, na nhazi akwa dị mfe.Nano barium sulfate nwere mmetụta nano dị mma.Nano barium sulfate / cellulose mix fiber na-emezigharị site na abụọ dị ka ihe eji eme ihe bụ ụdị ọhụrụ nke eriri ihe mejupụtara, nke nwere ike ịnọgide na-enwe ihe pụrụ iche nke akụkụ ọ bụla.Ọzọkwa, site na "mmekọrịta" n'etiti ha, ọ nwere ike ime ka adịghị ike nke otu ihe ma gosipụta njirimara ọhụrụ nke ihe ndị mejupụtara.
