Tekinoroji yo gupakira Technology Ikoranabuhanga rya Pretreatment Technology Ibicuruzwa bya plastiki

Iriburiro: Igikorwa cyo gukora cyaibicuruzwa bya pulasitikiahanini ikubiyemo inzira enye zingenzi: gushiraho ibishushanyo, kuvura hejuru, gucapa, no guterana. Kuvura isura ni igice cyingenzi cyingenzi. Kugirango tunoze imbaraga zo guhuza igipfundikizo no gutanga umusingi mwiza wo kuyobora isahani, inzira yo kubanza kuvura ni ngombwa.

Kugaragara hejuru yibicuruzwa bya plastiki
Ahanini harimo kuvura ibifuniko no kuvura amasahani. Mubisanzwe, plastike ifite urwego runini rwa kristu, polarite ntoya cyangwa idafite polarite, nimbaraga nke zo hejuru, bizagira ingaruka kumyambarire. Kubera ko plastiki ari insuliranteri idakora, ntishobora gushyirwaho neza hejuru ya plastike ukurikije uburyo rusange bwo gukwirakwiza amashanyarazi. Kubwibyo, mbere yo kuvura hejuru, hakenewe gukorwa progaramu yo kwitegura kugirango hongerwe imbaraga zo guhuza igipfundikizo no gutanga urwego rwo hasi ruyobora hamwe nimbaraga nziza zo guhuza isahani.

Gutegura igifuniko

Kwirinda bikubiyemo kwangirika kwa plastike, ni ukuvuga koza amavuta no gusohora ibintu hejuru, no gukora plastike, kugirango tunonosore neza.

1 、 Gutesha agaciro
Gutesha agaciroibicuruzwa bya pulasitiki. Kimwe no kwangirika kwibicuruzwa byicyuma, gutesha agaciro ibicuruzwa bya pulasitike birashobora gukorwa mugusukura hamwe nudukoko twangiza cyangwa kugabanuka hamwe namazi yo mumazi ya alkaline arimo surfactants. Kugabanuka hamwe na solge organic ikwiranye nogusukura paraffine, ibishashara, ibinure nibindi byumwanda kama hejuru ya plastiki. Ifumbire mvaruganda ikoreshwa ntigomba gushonga, kubyimba cyangwa kumena plastike, kandi ifite aho itetse, irahindagurika, idafite uburozi kandi ntigicanwa. Amazi yo mu mazi ya alkaline arakwiriye kwangiza plastiki irwanya alkali. Igisubizo kirimo soda ya caustic, umunyu wa alkaline hamwe na surfactants zitandukanye. Ikintu gikunze gukoreshwa cyane ni urukurikirane rwa OP, ni ukuvuga alkylphenol polyoxyethylene ether, idakora ifuro kandi ntiguma hejuru ya plastiki.

2 activ Gukora neza
Uku gukora ni ukunoza imiterere yubuso bwa plastiki, ni ukuvuga kubyara amatsinda amwe ya polar hejuru yubuso bwa plastike cyangwa kuyikomeretsa kugirango igifuniko gishobore guhindurwa byoroshye kandi byamamajwe hejuru yakazi. Hariho uburyo bwinshi bwo kuvura ibikorwa byo hejuru, nka okiside ya chimique, okiside ya flame, ibicanwa biva mu kirere hamwe na okiside ya corona isohora. Uburyo bukoreshwa cyane ni uburyo bwo kuvura imiti ya kirisiti ya christal, ikoreshwa cyane mu kuvura amazi ya chromic aside, kandi amata asanzwe ni 4.5% ya potasiyumu dichromate, amazi 8.0%, na 87.5% yibanze kuri acide sulfurike (irenga 96%).

Ibicuruzwa bimwe na bimwe bya pulasitike, nka polystirene na plastiki ya ABS, birashobora gutwikirwa mu buryo butaziguye hakoreshejwe imiti ya okiside. Kugirango ubone igifuniko cyiza, hakoreshwa kandi imiti ya okiside ya chimique. Kurugero, nyuma yo kwangirika, plastike ya ABS irashobora gushiramo amazi ya chromic acide ivanze. Uburyo busanzwe bwo kuvura ni 420g / L acide chromic na 200ml / L aside sulfurike (uburemere bwihariye 1.83). Uburyo busanzwe bwo kuvura ni 65 ℃ 70 ℃ / 5min10min, gukaraba amazi, no gukama. Ibyiza byo gushira hamwe na chromic acide ivura amazi ni uko nubwo imiterere yibicuruzwa bya plastike yaba igoye gute, irashobora kuvurwa neza. Ikibi nuko imikorere iteje akaga kandi hari ibibazo byumwanda.
Gutegura igifuniko

Intego yo kwitegura gutwikira igipfundikizo ni ugutezimbere ifatizo ryubuso hejuru ya plastiki no gukora icyuma cyo hasi cyicyuma hejuru ya plastiki. Igikorwa cyo kwitegura kirimo ahanini: gukanika imashini, kwangiza imiti, kuvura imiti, kuvura ubukangurambaga, kuvura ibikorwa, kugabanya imiti no gufata imiti. Ibintu bitatu byambere ni ugutezimbere igifuniko, naho ibintu bine byanyuma bigomba gukora icyuma cyo hasi.

1 、 Gukanika imashini hamwe na chimique
Gukoresha imashini no kuvura imiti ni ugukora ubuso bwa plastike hakoreshejwe uburyo bwa mashini hamwe nuburyo bwa chimique kugirango hongerwe aho uhurira hagati ya coater na substrate. Muri rusange abantu bemeza ko imbaraga zihuza zishobora kugerwaho no gukanika imashini zingana na 10% gusa byimbaraga za chimique.

2 asing Kwangiza imiti
Uburyo bwo gutesha agaciro kwifata hejuru ya plastike ni kimwe nuburyo bwo gutesha agaciro kwifata.

3 、 Gukangurira
Gukangurira ni ukwamamaza ibintu bimwe na bimwe byoroshye okiside, nka tin dichloride, titanium trichloride, nibindi, hejuru ya plastiki ifite ubushobozi bwa adsorption. Ibi byongeweho byoroshye okiside byoroshye mugihe cyo kuvura ibikorwa, hanyuma uyikora igabanuka kuri catalitiki ya kirisiti nuclei kandi iguma hejuru yibicuruzwa. Uruhare rwo gukangurira ni ugushiraho urufatiro rw'icyuma gikurikiraho.

4 、 Gukora
Gukora ni ukuvura hejuru yubukangurambaga hifashishijwe igisubizo cyibikoresho bya catalitiki ikora. Intego yacyo ni ugucengera ibicuruzwa byamamajwe hamwe nigabanuka ryamazi mugisubizo cyamazi kirimo okiside yumunyu wicyuma cyigiciro cyinshi, kuburyo ion zicyuma cyagaciro zagabanutse na S2 + n nka okiside, kandi ibyuma byagabanutse bigashyirwa kuri ubuso bwibicuruzwa muburyo bwa colloidal ibice, bifite ibikorwa bikomeye bya catalitiki. Iyo ubu buso bwinjijwe mumuti wibikoresho bya shimi, ibyo bice bihinduka ibigo bya catalitiki, byihutisha umuvuduko wibikorwa bya plaque.

5 treatment Kugabanya imiti
Mbere yo gusya imiti, ibicuruzwa byakorewe kandi byogejwe namazi meza byinjizwa mumurongo runaka wo kugabanya igisubizo cyumuti ukoreshwa mumasahani yimiti kugirango ugabanye kandi ukureho moteri idakarabye. Ibi bita kuvura kugabanya. Iyo umuringa wa shimi ushyizwemo, igisubizo cya fordedehide gikoreshwa mukugabanya imiti, kandi iyo nikel ya shimi yashizwemo, umuti wa sodium hypophosphite ukoreshwa mukugabanya imiti.

6 ating Isahani
Intego yo gusya imiti nugukora firime yicyuma ikora hejuru yibicuruzwa bya pulasitike kugirango habeho uburyo bwo gukwirakwiza amashanyarazi yicyuma cyibicuruzwa bya plastiki. Kubwibyo, isahani yimiti nintambwe yingenzi mumashanyarazi ya plastike.
