Ihe ndị a bụ okwu mmalite maka ojiji nke nano barium sulfate.

1. Ụlọ ọrụ plastik — mgbe emechara ya bariteigwe igwe egweri iheigwe

Ịtinye nano barium sulfate nke igwe igwe barite na-akpụzi na polymer iji nweta ihe mejupụtara ya nwere ike na ike dị elu adọtala ọtụtụ mmadụ. Dịka ọmụmaatụ, enwere ike itinye barium sulfate na polyethylene (PE), polypropylene (PP), polylactic acid (PLA), polytetrafluoroethylene (PTFE) na ihe ndị ọzọ. Karịsịa, akụrụngwa nke barium sulfate emeziwanyela nke ukwuu mgbe emezigharịrị elu.

Maka ọtụtụ ngwakọta polima, ka ọnụọgụ nke ihe na-agbanwe agbanwe na-abawanye, ike na ike nke ihe ndị mejupụtara ya na-abawanye na mbụ wee belata. Nke a bụ n'ihi na oke nke ihe na-agbanwe agbanwe ga-eduga na mmịpụta anụ ahụ dị iche iche n'elu nano barium sulfate, na-akpata nnukwu mmịpụta na polima ahụ, na-emetụta ihe ndị mejupụtara ya, ma na-eme ka ọ sie ike igwu egwu dị mma nke ihe ndị na-ejupụtaghị ihe; obere obere ihe na-agbanwe agbanwe ga-eme ka ntụpọ njikọ dị n'etiti nano barium sulfate na polima dịkwuo elu, na-ebute mbelata na ihe ndị mejupụtara ya.

Tinyere ọnụọgụgụ ihe na-agbanwe elu dị n'elu nwere mmetụta dị ukwuu na njirimara igwe nke ihe mejupụtara ya, ọnụọgụgụ barium sulfate bụkwa ihe dị mkpa. Nke a bụ n'ihi na ike nke nano barium sulfate buru ibu nke ukwuu, nke nwere ike ịrụ ọrụ n'ịrụ ọrụ mgbe etinyere ya na ihe mejupụtara ya, si otú a na-emepụta mmetụta siri ike. Agbanyeghị, mgbe ọdịnaya nke nano barium sulfate dị oke elu (karịa 4%), n'ihi njikọta ya na ihe mejupụtara ya na mgbakwunye nke ihe ndị na-adịghị arụ ọrụ, ntụpọ matrix na-abawanye, nke na-eme ka ihe mejupụtara ahụ dịkwuo mfe ịgbaji, si otú a na-eme ka ihe mejupụtara ya ka njọ.

2. Ụlọ ọrụ mkpuchi — mgbe emechara nhazi ya nabariteigwe igwe egweri iheigwe

Dịka ụdị agba, a na-ejikarị barium sulfate eme ihe n'ihe mkpuchi ma na-arụ ọrụ dị mkpa n'ime ka ọkpụrụkpụ ya dịkwuo mma, iguzogide abrasion, iguzogide mmiri, iguzogide okpomọkụ, ike elu ya na iguzogide mmetụta nke ihe mkpuchi ahụ. Na mgbakwunye, n'ihi obere mmịpụta mmanụ ya na ikike njupụta ya dị elu, enwere ike iji ya mee ihe mkpuchi mmiri, praịma, mkpuchi etiti na mkpuchi mmanụ iji belata ọnụ ahịa mkpuchi ahụ. Ọ nwere ike dochie 10% ~ 25% nke titanium dioxide na mkpuchi mmiri. Nsonaazụ ya na-egosi na a na-eme ka ọcha ahụ ka mma ma a naghị ebelata ike nzuzo ya.

Àgwà nke superfine barium sulfate maka mkpuchi bụ: 1) nha obere ihe na nkesa nha obere ihe; 2) Ọ na-apụta ìhè mgbe a gbasasịrị ya na mmiri resin; 3) Ọ na-agbasa nke ọma na ihe mkpuchi isi; 4) Enwere ike iji ya dị ka ihe na-agbasa ya na njikọta ya na agba organic; 5) Ọ nwere ike imeziwanye ihe onwunwe anụ ahụ.

3. Ụlọ ọrụ akwụkwọ — mgbe nhazi ya gasịrị site na bariteihe mgbada kwụ ọtọigwe igwe igwe

A na-ejikarị Barium sulfate eme ihe n'ụlọ ọrụ mmepụta akwụkwọ n'ihi na ọ kwụsiri ike nke ọma n'anụ ahụ na kemịkalụ, ike ya dị oke elu, nnukwu ọcha, na ịmịkọrọ ụzarị ndị na-emerụ ahụ.

Dịka ọmụmaatụ, akwụkwọ carbon bụ ihe a na-ahụkarị n'ụlọ akwụkwọ na ihe ndị ọzọ dị n'ọfịs, mana elu ya dị mfe ịcha agba, yabụ achọrọ barium sulfate iji nweta uru nnabata mmanụ dị elu, nke nwere ike ime ka ink nke akwụkwọ ahụ ka mma; Nha nke ihe ndị ahụ dị obere ma dịkwa otu, nke nwere ike ime ka akwụkwọ ahụ dị larịị ma mee ka igwe ghara iyi ya nke ọma.

4. Ụlọ ọrụ eriri kemịkal — mgbe emechara ya site na nhazi ya bariteihe mgbada kwụ ọtọigwe igwe igwe
