Ibyinshi mubikoresho fatizo byibikoresho byangiritse ni ibikoresho bya bismuth bitari plastike, kandi biragoye kubitunganya mubicuruzwa byarangije igice cyonyine.Kubwibyo, birakenewe gukoresha ibinyabuzima byo hanze cyangwa ibinyabuzima bidahuza cyangwa bivanze.Ibikoresho bitandukanye bidasanzwe byangirika bikorerwa muburyo bukomeye kandi bwuzuye kugirango bakore icyondo hamwe nogukwirakwiza ibice bimwe, gukwirakwiza amazi amwe, plastike imwe nimwe byoroshye gukora nibicuruzwa bitarangiye.Birakenewe gufata inzira yumusaruro hamwe nubushobozi buhanitse, kuvanga neza no kuvanga neza.
(1) Guhuza ibice
Bilet (icyondo) irashobora gukorwa mubicuruzwa bifite ubwinshi bwinshi muguhitamo ibice bifatika.Mu buryo bw'igitekerezo, urwego rumwe rufite ubunini bwa santimetero zitandukanye n'ibikoresho bitandukanye byarageragejwe, kandi ubwinshi bwinshi bwari bumwe.Ibyo ari byo byose, porosity yari 38% ± 1%.Kubwibyo, kumupira wubunini bumwe, ubwinshi bwubwinshi nubwinshi bwabyo ntibigenga ubunini bwumupira nibintu bifatika, kandi burigihe bishyirwa muburyo bwa mpande esheshatu hamwe numubare uhuza 8.
Uburyo bwo gutondekanya uburyo bwa tekinike imwe yingero imwe ifite cube, inkingi imwe ya oblique, inkingi ihuriweho, ishusho ya piramide, na tetrahedron.Uburyo butandukanye bwo gutondekanya ubunini bungana bwerekanwe ku gishushanyo cya 24. Isano iri hagati yuburyo bwo kubika uduce tumwe na tumwe twerekanwe mu mbonerahamwe ya 2-26.
Kugirango twongere ubwinshi bwibintu kandi bigabanye ubukana, hakoreshwa urwego rwubunini buke buke, ni ukuvuga, umubare runaka wimibumbe mito yongewe kumurongo munini kugirango wongere ibice bigize urwego, nubusabane hagati yubunini bufitwe numuzingi hamwe na porosity byerekanwe kumeza.2-27.
Hamwe nibikoresho bya clinker, ibice bitobito ni 4. 5 mm, ibice bigereranijwe ni mm 0,7, ibice byiza ni 0,09 mm, naho ihinduka ryimiterere ya clinker ryerekanwa kumashusho 2-5.
Kuva ku gishushanyo cya 2-5, ibice bito ni 55% ~ 65%, ibice byo hagati ni 10% ~ 30%, naho ifu nziza ni 15% ~ 30%.Ikigaragara kigaragara gishobora kugabanuka kugera kuri 15.5%.Birumvikana ko ibigize ibikoresho byihariye byo kwangara birashobora guhindurwa muburyo bukurikije imiterere yumubiri hamwe nuduce duto twibikoresho.
(2) Umukozi uhuza ibicuruzwa bidasanzwe
Ukurikije ubwoko bwibikoresho bidasanzwe byangiritse nuburyo bwo kubumba, binders zishobora gukoreshwa ni:
.
(2) Uburyo bwo gukanda, harimo amavuta, glycol,
Inzoga za polyvinyl, methyl selulose, krahisi, dextrin, maltose na glycerine.
.
.plasitike: polyethylene glycol, dioctane Acide Fosifori, dibutyl peroxide, nibindi.;imiti ikwirakwiza: glycerine, aside oleic;umusemburo: Ethanol, acetone, toluene, nibindi nkibyo.
.amavuta: aside stearic.
.
.sulfite pulp imyanda isukuye, methyl selulose, gum arabic, dextrin cyangwa imyunyu ngugu ya organic organique na organic organique, nka acide fosifori cyangwa fosifate.
(3) Ibivanze kubicuruzwa bidasanzwe byangiritse
Kugirango utezimbere ibintu bimwe na bimwe byihariye byo kuvunika ibintu, kugenzura imiterere ya kristu ihindura ingingo, kugabanya ubushyuhe bwumuriro wikintu, hanyuma wongereho umubare muto wivanga mubikoresho.Izi mvange ni cyane cyane oxyde yicyuma, oxyde itari ibyuma, oxyde yisi idasanzwe, fluoride, boride na fosifate.Kurugero, kongeramo 1% ~ 3% acide boric (H2BO3) kuri γ-Al2O3 birashobora guteza imbere ihinduka.Kwiyongera kwa 1% kugeza 2% TiO2 kuri Al2O3 birashobora kugabanya cyane ubushyuhe bwumuriro (hafi 1600 ° C).Kwiyongera kwa TiO2, Al2O3, ZiO2, na V2O5 kuri MgO biteza imbere imikurire ya cristobalite kandi bikagabanya ubushyuhe bwumuriro wibicuruzwa.Kwiyongera kwa CaO, MgO, Y2O3 nibindi byongerwaho ibikoresho bya ZrO2 birashobora gukorwa mubisubizo bya cubic zirconia bihamye kuva mubushyuhe bwicyumba kugeza 2000 ° C nyuma yo kuvura ubushyuhe bwinshi.
(4) Uburyo n'ibikoresho byo kuvanga
Uburyo bwumye bwo kuvanga
Ivangavanga rikomeye rivanze ryakozwe na Shandong Konyle rifite ubunini bwa 0.05 ~ 30m3, rikwiriye kuvanga ifu zitandukanye, granules, flake hamwe n’ibikoresho byo hasi cyane, kandi bifite ibikoresho byongeramo amazi kandi bitera.
2. Uburyo bwo kuvanga amazi
Muburyo busanzwe bwo kuvanga amazi, ibigize ibikoresho bitandukanye bishyirwa mubivanga umubumbe ufite ibikoresho byo gukingira neza.Nyuma yo gukora ibishishwa, hongewemo plasitike nibindi bivanga kugirango hongerwe ubwinshi bwibyondo, kandi imvange ivangwa neza mumashanyarazi ya vertical shaft umubumbe wivanga, hanyuma ugahunika hanyuma ukumishwa mumashanyarazi ya spray.
Kuvanga umubumbe
3. Uburyo bwo guhuza plastike
Kugirango habeho uburyo bwo guhuza uburyo butandukanye bwo guhuza ibicuruzwa bidasanzwe byangiritse bikwiranye no gukora plastike cyangwa gukora silige.Muri ubu buryo, ibikoresho bitandukanye, ibivanze, plasitike, hamwe n’amavuta n'amazi bivangwa neza kuvanga umubumbe w’umubumbe, hanyuma bikavangwa hanyuma bikavangwa no kuvangavanga cyane cyane kugirango bivaneho ibyondo.Kugirango tunonosore plastike yicyondo, icyondo kivangwa nibikoresho bishaje, kandi icyondo gikorerwa kuvanga kabiri kumashini yibumba mbere yo kubumba.Koneile itanga umusaruro-mwinshi kandi uvanze nkuko bigaragara hano:
Kuvanga neza kandi bikomeye
Kuvangavanga
4. Uburyo bwo kuvanga igice cyumye
Birakwiye kuvanga uburyo nubushuhe buke.Gukoresha uburyo bwo kuvanga igice cyumye kirakenewe kubicuruzwa bidasanzwe bivunika bigizwe nimashini ikorwa na granulaire (coarse, medium and fine fine-etaire).Ibigize bikorerwa muvanga umucanga, urusyo rutose, kuvanga umubumbe cyangwa kuvanga ku gahato.
Uburyo bwo kuvanga ni ukubanza gukama kuvanga ibyiciro bitandukanye bya granules, ukongeramo igisubizo cyamazi kirimo binder (inorganic or organic), hanyuma ukongeramo ifu nziza ivanze (harimo infashanyo yo gutwika, ibikoresho byo kwagura, nibindi byongeweho).Intumwa) ivanze neza.Igihe cyo kuvanga muri rusange ni 20 ~ 30min.Icyondo kivanze kigomba gukumira gutandukanya ingano kandi amazi agomba kugabanwa neza.Nibiba ngombwa, ibyondo bigomba gufatwa neza mugihe cyo kubumba.
Ubushuhe bwibicuruzwa byakozwe mubinyamakuru byondo bigenzurwa kuri 2,5% kugeza 4%;ibirimo ubuhehere bwibicuruzwa bimeze nk'ibyondo bigenzurwa kuri 4.5% kugeza kuri 6.5%;hamwe nubushuhe bwibicuruzwa byanyeganyezwa bigenzurwa kuri 6% kugeza 8%.
(1) Imikorere ya tekinike ya CMP yuruhererekane rwingufu zivanga umubumbe wakozwe na Kone.
(2) Imikorere ya tekiniki yo kuvanga umucanga utose
5. Uburyo bwo kuvanga ibyondo
Uburyo bwo kuvanga ibyondo ni kubyaza umusaruro udasanzwe udasanzwe twa ceramic ceramic, cyane cyane icyondo cyo kubumba inshinge za gypsum, guteramo no gutera inshinge.Uburyo bwo gukora ni ukuvanga ibikoresho bitandukanye bibisi, imbaraga zongera imbaraga, guhagarika imiti, imvange hamwe na 30% kugeza 40% byamazi meza mumashini yumupira (kuvanga urusyo) hamwe nimirongo idashobora kwambara, hanyuma ukavanga no gusya nyuma yigihe runaka cya igihe., bikozwe mubyondo byo kubumba.Muburyo bwo gukora ibyondo, birakenewe kugenzura ubwinshi na pH byicyondo ukurikije ibiranga ibintu nibisabwa kugirango icyondo ubwacyo.
Kuvanga imbaraga zikomeye
Ibikoresho nyamukuru bikoreshwa muburyo bwo kuvanga ibyondo ni urusyo rwumupira, compressor yumuyaga, gukuramo ibyuma bitose, pompe yicyondo, vacuum deaerator, nibindi nkibyo.
6. Uburyo bwo kuvanga ubushyuhe
Paraffin na resin ishingiye ku bikoresho ni ibintu bikomeye (cyangwa viscous) ku bushyuhe busanzwe, kandi ntibishobora kuvangwa n'ubushyuhe bw'icyumba, kandi bigomba gushyuha no kuvangwa.
Paraffin ikoreshwa nka binder mugihe ukoresheje inzira ishyushye yo guta.Kubera ko gushonga ibishashara bya paraffine ari 60 ~ 80 ° C, ibishashara bya paraffin bishyuha hejuru ya 100 ° C mu kuvanga kandi bifite amazi meza.Noneho ifu nziza yibikoresho byongewe kuri paraffine yamazi, hanyuma nyuma yo kuvanga no kuvanga byuzuye, ibikoresho birategurwa.Igishashara gishashara gikozwe no gushyuha bishyushye.
Ibikoresho nyamukuru bivanga byo gushyushya imvange ni agiteri ishyushye.
