Nigute ushobora gukora ifu ya latex?

Ifu ya polymer polymer (RDP) nibikoresho byingenzi bikoreshwa cyane mubwubatsi, amatara, ahimbye nibindi bice. Yakozwe mugukama emulsion kandi ifite agaciro kandi igatangazwa.

1. Imyiteguro yibintu
Ibikoresho nyamukuru byifatizo byo gukora ifu ya latex ikubiyemo:
Equlmer Edulsion: nka Polyvinyl Inzoga (Pva), Evyle-vinyle acetate (eva), Styrene-acrylate (sa), nibindi
Protective colloid: such as polyvinyl alcohol, methyl cellulose, hydroxypropyl methyl cellulose, etc., used to prevent particles from sticking during the drying process.
DeFomer: Byakoreshejwe mu gukuraho ibibyimba mubikorwa, nka peteroli ya silico na polyetr.
Stabilizer: nka sodium dodecybenlbene sulfonate (SDB), sodium polyacrylate, nibindi, ikoreshwa mu gutuza sisitemu ya emulsion.

2. Kwitegura kwamugana
Hitamo monomers ikwiye ukurikije formulaire ya reaction ya polymeration kugirango utegure elulsion polymer hamwe nibiranga. Mugihe cyo gutegura EMULSION, intambwe zingenzi zikurikira zigomba kwitonderwa:
Guhitamo Monomer na Ratio: Hitamo monomers ikwiye, nka Ethylene, vinyl acetate, nibindi, ukurikije intego yibicuruzwa byanyuma, hanyuma umenye ibipimo byayo kugirango birebe imikorere ya emulision.
Amatwi menshi: Mubisanzwe umuvuduko ukabije wubusa ukoreshwa mugukandagura monomer muri elulmer polymer. Igitekerezo cyinshi gikeneye gukorwa mubihe bigenzurwa cyane, birimo ubushyuhe, umuvuduko ukabije, uwatangije kwiyongera kwiyongereyeho, nibindi
Ongeraho Colloid irinda kandi stabilizer: ongeramo umubare ukwiye kugirango ukingire hamwe na stabilizer kuri emulision kugirango wirinde emulision guhiga mugihe cyo gukama.

3. Kwitegura Emalion
Mbere yo gukama, emulsion igomba gutemwa, harimo cyane cyane nintambwe zikurikira:
Filtration: Kuraho umwanda muri emulsion unyuze muyungurura cyangwa kujya muke kugirango umenye neza ko emulision.
Kwibandaho: Witondere emulsion ibintu bihamye binyuze muri ibyo uhumeka cyangwa umuriro wa membrane kugirango utezimbere imikorere yumye.

4. Spray yumye
Spray yumye nigikorwa cyibanze cyo gukora ifu ya latex. Intambwe Zihariye ni izi zikurikira:
Guhitamo Spray umunara wumye: Hitamo ibikoresho byumye bitera ukurikije imiterere nibisohoka bya Emulision. Ibikoresho bikunze gukoreshwa birimo centrifugal spray umunara wumisha hamwe nigitutu cyatera umunara wumye.
Gushiraho ibipimo byumisha: Shiraho ubushyuhe bwikirere bwikirere, ubushyuhe bwikirere butemewe hamwe nigitutu cya spray. Mubisanzwe, ubushyuhe bwikirere bwindege bugenzurwa na 150-200 ℃, nubushyuhe bwikirere butemewe bugenzurwa na 60-80 ℃.
Gutera inzira yo kumisha: emulsion yateguwe yatoboye mubitonyanga byiza binyuze muburyo bworoshye, kandi ihuza byihuse numwuka ushushe mumunara wumye, kandi amazi ahumeka kugirango akore ifu yumye.
Icyegeranyo cya Powder: Ifu yumye ya lowx yakusanyijwe nigice cyumuyaga cyangwa akayunguruzo. Ifu yakusanyijwe ikusanyijwe igomba gukonjeshwa kandi ibice binini byakuweho kugirango ugenzure kugirango umenye neza ibicuruzwa.

5. Inyandiko yo gutunganya no gupakira
Ifu yumye itagaragara ya latex igomba gutoranya neza kugirango hategurwe imikorere ihamye nububiko butekanye. Kohereza ahanini birimo:
Kuvura no gutombora: Ongeramo abakozi barwanya imitekerereze (nka talcum dioxyde delicon) hejuru yifu ya latex kugirango wirinde ifu yo gukomera no gutwara abantu.
Gupakira: Ukurikije ubufasha bwabakiriya, ifu ya latex ipakiye mubushuhe-gihamya n'umukungugu utanga ivumbi cyangwa ingunguru. Ubushuhe bugomba kugenzurwa cyane mugihe cyo gupakira kugirango bumurinde ifu yo gukuramo ubushuhe.

6. Igenzura ryiza
Mugihe cyimikorere, kugenzura ubuziranenge birasabwa kugirango ibipimo ngenderwaho byifu ya latex yujuje ibisabwa. Ibintu bisanzwe byo kugenzura ubuziranenge birimo:
Ikwirakwizwa ryinshi: Ikwirakwizwa ryifu ryagaragaye numusesenguzi wa laser usesengura kugirango ugire uburinganire bwibicuruzwa.
Imbaraga zo gutanga: Gerageza imbaraga zo gupfusha ifu ya latex kuri substrate zitandukanye kugirango urebe imikorere yacyo.
Kureka: Kuvanga ifu ya latex n'amazi yo kureba niba ishobora gutatanya no gusubizwa muri leta ya emsion.

7. Gusaba no kwirinda
Ifu yongeye kuvugurura ifu ya latex ikoreshwa cyane mu kubaka minisiteri, tile imeza, sisitemu yo kugenzura urukuta rwinyuma nizindi nzego. Ingingo zikurikira zigomba kuboneka mugihe ukoresheje:

Imiterere yububiko: Ifu ya landx igomba kubikwa mubidukikije byumye kandi bikonje kugirango wirinde ubushyuhe bwinshi nubushuhe.
Ikigereranyo cyo gukoresha: Ukurikije ibisabwa byihariye byo gusaba, ongeramo ifu ya nyakwigendera kugirango ubone imikorere myiza.
Hamwe nizindi nguzanyo: Ifu yoroheje ya latex ikoreshwa cyane hamwe nizindi nguzanyo (nka selile ether, defomer) kugirango yongere imikorere yibikoresho.

Ifu yongeye kuvugurura ifu ya latex hamwe nibikorwa byiza birashobora kubyara neza. Mubyasaruro nyabyo, birakenewe muguhindura ukurikije umusaruro wihariye hamwe nibisabwa ibicuruzwa kugirango ubone ubuzima bwiza kandi bwizewe bwibicuruzwa byanyuma.
