Igisubizo

Barium sulfate ningirakamaro yingenzi ya chimique yibikoresho bitunganyirizwa mumabuye mbisi ya barite.Ntabwo ifite imikorere myiza ya optique gusa hamwe nubushakashatsi bwimiti, ariko ifite n'ibiranga umwihariko nkubunini, ingano ya kwant ndetse ningaruka za interineti.Kubwibyo, ikoreshwa cyane mubitambaro, plastike, impapuro, reberi, wino na pigment hamwe nizindi nzego.Nanometero barium sulfate ifite ibyiza byubuso bwihariye bwihariye, ibikorwa byinshi, gutatanya neza, nibindi birashobora kwerekana imikorere myiza iyo ikoreshejwe mubikoresho byinshi.HCMilling (Guilin Hongcheng) ni uruganda rukora umwugabariteurusyoimashini.Iwacubariteuruzigaurusyo imashini irashobora gusya 80-3000 mesh barite ifu.Ibikurikira nintangiriro yo gusaba imirima ya nano barium sulfate.

1. Inganda za plastiki - nyuma yo gutunganya hamwe bariteurusyoimashini

Ongeramo nano barium sulfate yatunganijwe na barite yo gusya imashini ya polymer kugirango ibone ibikoresho byimbaraga hamwe nimbaraga zikomeye byakwegereye abantu benshi.Kurugero, barium sulfate irashobora kongerwaho polyethylene (PE), polypropilene (PP), aside polylactique (PLA), polytetrafluoroethylene (PTFE) nibindi bikoresho.By'umwihariko, ubukanishi bwa barium sulfate bwatejwe imbere cyane nyuma yo guhindura ubuso.

Kubintu byinshi bya polymer, hamwe no kwiyongera kwinshi kwa modifier, imbaraga nubukomezi bwibikoresho byahujwe byiyongera mbere hanyuma bikagabanuka.Ibi ni ukubera ko ubwinshi bwibihindura bizaganisha kuri adsorption yumubiri itandukanye hejuru ya nano barium sulfate, itera agglomeration ikomeye muri polymer, bigira ingaruka kumiterere yibikoresho byibikoresho, kandi bikagorana gukina ibintu byiza biranga ibyuzuye;Umubare muto wo guhindura bizongera ubusembwa bwimikorere hagati ya nano barium sulfate na polymer, bikavamo kugabanuka kumiterere yimashini yibigize.

Usibye ingano yavuzwe haruguru yubuso bwo guhindura ibintu bigira ingaruka zikomeye kumiterere yubukorikori, ingano ya barium sulfate nayo ni ikintu cyingenzi.Ni ukubera ko imbaraga za nano barium sulfate nini cyane, zishobora kugira uruhare mukubyara iyo zongewe kuri compte, bityo bikabyara ingaruka zikomeye.Nyamara, iyo ibiri muri sulfate ya nano barium ari hejuru cyane (hejuru ya 4%), kubera agglomeration yayo muri compte hamwe no kongeramo uduce duto duto, inenge ya matrix iriyongera, bigatuma compte ikunda kuvunika, bityo bigatuma U imiterere ya mashini yibigize nabi.Kubwibyo, ingano yinyongera ya barium sulfate igomba kuba muburyo bukwiye bwa mashini.

2. Inganda zo gutwikira - nyuma yo gutunganya hamwebariteurusyoimashini

Nkubwoko bwa pigment, barium sulfate ikoreshwa cyane mugutwikiriye kandi igira uruhare runini mukuzamura umubyimba, kurwanya abrasion, kurwanya amazi, kurwanya ubushyuhe, ubukana bwubutaka no kurwanya ingaruka ziterwa.Byongeye kandi, kubera amavuta make yakira hamwe nubushobozi bwo kuzuza cyane, irashobora gukoreshwa mumazi ashingiye kumazi, primers, gutwikira hagati hamwe no gusiga amavuta kugirango igabanye ibiciro.Irashobora gusimbuza 10% ~ 25% ya dioxyde ya titanium mumazi ashingiye kumazi.Ibisubizo byerekana ko umweru utezimbere kandi imbaraga zo guhisha ntizigabanuka.

Ibiranga superumine barium sulfate yo gutwikira ni: 1) ingano yingirakamaro cyane nubunini bugabanijwe;2) Biragaragara iyo bitatanye mugisubizo cya resin;3) Gutandukana neza mubikoresho bifatika;4) Irashobora gukoreshwa nkumukozi ukwirakwiza hamwe na pigment organic;5) Irashobora kunoza imiterere yumubiri.

3. Inganda zimpapuro - nyuma yo gutunganywa na bariteuruzigaurusyo imashini

Barium sulfate ikoreshwa kenshi mu nganda zikora impapuro kubera ko ihagaze neza ku mubiri no mu miti, ubukana buringaniye, umweru munini, no kwinjiza imirase yangiza.

Kurugero, impapuro za karubone ni ibintu bisanzwe byigirwa nibikoresho byo mu biro, ariko ubuso bwayo bworoshye kurimbisha, bityo sulfate ya barium isabwa kugira agaciro gakomeye ko kwinjiza amavuta, bishobora kunoza irangi ryimpapuro;Ingano yingirakamaro ni ntoya kandi imwe, irashobora gutuma impapuro zireshya kandi bigatuma imyenda idashira.

4. Inganda za fibre chimique - nyuma yo gutunganywa na bariteuruzigaurusyo imashini

Fibre fibre, izwi kandi nka "ipamba yubukorikori", isa na fibre naturel ya kamere muri kamere, nka anti-static, kwinjiza neza neza, gusiga irangi byoroshye, no gutunganya imyenda byoroshye.Nano barium sulfate ifite ingaruka nziza nano.Nano barium sulfate / fibre yongeye kuvangwa ya selile ya selile ikozwe muri byombi nkibikoresho fatizo ni ubwoko bushya bwa fibre fibre, ishobora kugumana imiterere yihariye ya buri kintu.Byongeye kandi, binyuze muri "synergie" hagati yabo, irashobora kuzuza ibitagenda neza kubintu bimwe kandi ikerekana ibintu bishya byibikoresho.
