Gutesha agaciro
1. Imikorere: Kuraho amavuta yibinure hamwe nundi mwanda kama hejuru yibikoresho kugirango ubone ingaruka nziza ya electroplating kandi wirinde umwanda mubikorwa bizakurikiraho.
2. Urwego rwo kugenzura ubushyuhe: 40 ~ 60 ℃
3. Uburyo bwibikorwa:
Hifashishijwe saponification na emulisation yumuti, intego yo gukuraho irangi ryamavuta irashobora kugerwaho.
Gukuraho amavuta yinyamanswa nimboga bishingiye cyane cyane kuri saponification reaction.Ibyo bita saponification ni inzira yo kuvura imiti hagati yamavuta na alkali mumazi yangirika kugirango itange isabune.Amavuta yari asanzwe adashonga mumazi aboramo isabune na glycerine zishonga mumazi, hanyuma bikavaho.
4. Ibintu bikeneye kwitabwaho:
1) Ultrasonic oscillation irashobora kongera ingaruka zo kwangirika.
2) Iyo kwibumbira hamwe kwifu yifu idahagije, ingaruka zo kugabanuka ntizishobora kugerwaho;mugihe kwibumbira hamwe ari byinshi, igihombo kizaba kinini kandi ikiguzi kiziyongera, bityo rero bigomba kugenzurwa murwego rushimishije.
3) Iyo ubushyuhe budahagije, ingaruka zo kugabanuka ntabwo ari nziza.Kongera ubushyuhe birashobora kugabanya ubuso bwibisubizo byumuti hamwe namavuta kandi byihutisha ingaruka mbi;iyo ubushyuhe buri hejuru cyane, ibikoresho bikunda guhinduka.Ubushyuhe bugomba kugenzurwa cyane mugihe gikora.
4) Nyuma yo gutesha agaciro, ubuso bwibikoresho bugomba kuba bwuzuye.Niba hari ukwanga kugaragara hagati yigitonyanga cyamazi nuburyo bugaragara, bivuze ko ibikorwa bitujuje ibisabwa.Subiramo imikorere hanyuma uhindure ibipimo mugihe.
Gutura
Uburyo bwibikorwa:
Umubyimba wagura ibikorwa kugirango ugere kuri micro-ruswa hejuru, mugihe woroshye ibintu ubwabyo, ukarekura imihangayiko itaringanijwe iterwa no guterwa inshinge cyangwa ibikoresho, kugirango inzira ikurikiraho ishobora kuba imwe kandi ikangirika neza.
Uburyo bwo kugenzura ibibazo byimbere yibikoresho bya electroplating bizaba bitandukanye kubikoresho bitandukanye.Kuri ABS, uburyo bwo kwibiza acide glacial acetic bukoreshwa muri rusange.
OCoarsening
1. Urwego rwo kugenzura ubushyuhe: 63 ~ 69 ℃
2. plastike ya ABS ni terpolymer ya acrylonitrile (A), butadiene (B) na styrene (S).Mugihe cyo gukomera, ibice bya pulasitike birimo gukora ibyobo, bigatuma hydrophobique yo hejuru ya hydrophilique, kuburyo igipande cyometseho gifata igice cya plastiki kandi kigafatanwa neza.
Icyitonderwa:
1) Umuti mwinshi wa chromium ufite gushonga byihuse no kwihuta hamwe no gufunga neza;ariko mugihe agaciro ka acide chromic na acide sulfurike irenze 800 g / L, igisubizo kizagwa, bityo rero birakenewe ko gazi ikomeza.
2) Iyo kwibandaho bidahagije, ingaruka mbi ni mbi;iyo kwibumbira hamwe ari byinshi, biroroshye kurenza urugero, kwangiza ibikoresho, no kuzana igihombo kinini no kongera ikiguzi.
3) Iyo ubushyuhe budahagije, ingaruka mbi ntizaba nziza, kandi iyo ubushyuhe buri hejuru cyane, ibikoresho bikunda guhinduka.
④Kutabogama (igice nyamukuru ni aside hydrochloric)
1. Imikorere: Sukura chromium ya hexavalent isigaye muri micropores yibikoresho nyuma yo gukomera no kwangirika kugirango wirinde kwanduza inzira ikurikira.
2. Uburyo bwibikorwa: Mugihe cyo gukomera, ibice bya reberi yibikoresho bishonga, bigakora ibyobo, kandi hazaba hasigaye amazi yimbere.Kuberako ioni ya chromium ion mumazi ya roughening ifite ibintu bikomeye bya okiside, bizanduza inzira ikurikira.Acide Hydrochloric irashobora kugabanya kugabanuka kwa chromium ion, bityo igatakaza ibintu bya okiside.
3. Ibintu bikeneye kwitabwaho:
1) Acide Hydrochloric iroroshye guhindagurika, gukurura gaze birashobora kongera imbaraga zo kutabogama no gukora isuku, ariko umwuka wo mu kirere ntiworoshye kuba munini cyane, kugirango wirinde gutakaza aside irike ya hydrochlorike.
2) Iyo kwibandaho bidahagije, ingaruka zo gukora isuku ni mbi;iyo kwibumbira hamwe ari byinshi, igihombo cyo gukora ni kinini kandi igiciro kiriyongera.
3) Ubwiyongere bwubushyuhe burashobora kongera ingaruka zogusukura.Iyo ubushyuhe buri hejuru cyane, igihombo cya volatilisation kizaba kinini, bizamura ibiciro kandi bihumanya ikirere.
4) Mugihe cyo gukoresha, ioni ya chromium ion izegeranya kandi yiyongere.Iyo amazi yijimye icyatsi kibisi, bivuze ko hariho ioni nyinshi za chromium kandi zigomba gusimburwa buri gihe.
Gukora (catalysis)
1. Imikorere: Shira urwego rwa pallodium ya colloidal hamwe nibikorwa bya catalitiki hejuru yibikoresho.
2. Uburyo bwibikorwa: polymers zirimo amatsinda akora zirashobora gukora inganda hamwe nicyuma cyagaciro.
3. Icyitonderwa:
1) Ntukangure amazi akora, bitabaye ibyo bizatera umurwanashyaka kubora.
2) Ubwiyongere bwubushyuhe burashobora kongera ingaruka zo kurohama kwa palladium.Iyo ubushyuhe buri hejuru cyane, uyikora azabora.
3) Iyo kwibumbira hamwe kwa activate bidahagije, ingaruka yimvura ya palladium ntabwo iba ihagije;iyo kwibumbira hamwe ari byinshi, igihombo cyo gukora ni kinini kandi igiciro kiriyongera.
Nikel
1. Igenzura ry'ubushyuhe: 25 ~ 40 ℃
2. Imikorere: Shira icyuma kimwe kumurongo hejuru yibikoresho, kugirango ibikoresho bihinduke bivuye kubatayobora bikayobora.
3. Ibintu bikeneye kwitabwaho:
1) Acide Hypophosphorous nikintu kigabanya nikel.Iyo ibirimo ari byinshi, umuvuduko wo kubitsa uziyongera kandi igipande cya plaque kizaba cyijimye, ariko ituze ryumuti wibisahani uzaba muke, kandi bizihutisha umuvuduko wibisekuruza bya hypophosphite radicals, kandi igisubizo cyo kubumba kizoroha kubora.
2) Mugihe ubushyuhe bwiyongera, igipimo cyo guta igisubizo cya plaque kiriyongera.Iyo ubushyuhe buri hejuru cyane, kubera ko igipimo cyo kubitsa cyihuta cyane, igisubizo cyisahani gikunda kwangirika kandi igisubizo cyubuzima kigufi.
3) Agaciro pH kari hasi, umuvuduko wibisubizo byumuvuduko uratinda, kandi umuvuduko wibimera wiyongera iyo pH yiyongereye.Iyo agaciro ka PH kari hejuru cyane, igipfundikizo kibitswe vuba kandi ntigicye bihagije, kandi ibice bikunda kubyara.
