Umusaruro wuburyo bwa Redispersible Polymer Powder

Igikorwa cyo gukora ifu ya polymer isubirwamo (RPP) ikubiyemo ibyiciro byinshi, harimo polymerisation, kumisha spray, na nyuma yo gutunganywa. Dore incamake yuburyo busanzwe bwo gukora:

1. Polymerisation:

Inzira itangirana na polymerisation ya monomers kugirango itange polymer ihamye cyangwa emulsion. Guhitamo ba monomers biterwa nibintu byifuzwa hamwe nibisabwa bya RPP. Monomers isanzwe irimo vinyl acetate, Ethylene, butyl acrylate, na methyl methacrylate.

1. Gutegura Monomer: Monomers isukurwa ikavangwa n'amazi, abitangiza, nibindi byongerwaho mumitsi ya reaction.
2. Polymerisation: Uruvange rwa monomer ruhura na polymerisiyasi munsi yubushyuhe bugenzurwa, umuvuduko, hamwe nubushyuhe. Abatangije batangiza polymerisation reaction, biganisha kumurongo wa polymer.
3. Gutezimbere: Surfactants cyangwa emulisiferi yongeweho kugirango ihagarike gukwirakwiza polymer no gukumira coagulation cyangwa agglomeration ya polymer.

2. Gusasira Kuma:

Nyuma ya polymerizasiyo, gukwirakwiza polymer bikorerwa spray yumye kugirango ihindurwe ifu yumye. Kuma kumisha bikubiyemo atomisiyo yo gutatanya mumatonyanga meza, hanyuma akumishwa mumazi ashyushye.

1. Atomisiyoneri: Ikwirakwizwa rya polymer risunikwa kuri spray nozzle, aho ryinjizwa mu bitonyanga bito ukoresheje umwuka ucanye cyangwa atomizer ya centrifugal.
2. Kuma: Ibitonyanga byinjizwa mu cyumba cyumisha, aho bihurira n'umwuka ushushe (ubusanzwe ushyuha ku bushyuhe buri hagati ya 150 ° C na 250 ° C). Ihinduka ryihuse ryamazi ava mubitonyanga biganisha kumubiri.
3. Ikusanyirizo ry'ibice: Ibice byumye byakusanyirijwe mu cyumba cyumye ukoresheje cyclone cyangwa akayunguruzo. Ibice byiza birashobora gukurikiranwa kugirango bikureho ibice binini kandi byemeze ko ingano zingana.

3. Nyuma yo gutunganywa:

Nyuma yo kumisha spray, RPP ikora intambwe nyuma yo gutunganyirizwa kunoza imitungo yayo no kwemeza ibicuruzwa neza.

1. Gukonjesha: RPP yumye ikonjeshwa ubushyuhe bwicyumba kugirango wirinde kwinjiza neza no kwemeza ibicuruzwa neza.
2. Gupakira: RPP ikonje ipakirwa mumifuka cyangwa ibikoresho birinda ubushuhe kugirango birinde ubushuhe nubushuhe.
3. Kugenzura ubuziranenge: RPP ikorerwa igeragezwa ryubuziranenge kugirango igenzure imiterere yumubiri nu miti, harimo ingano y’ibice, ubwinshi bwinshi, ibirimo ubushuhe busigaye, hamwe na polymer.
4. Ububiko: RPP yapakiwe ibikwa ahantu hagenzuwe kugirango igumane ituze nubuzima bwayo kugeza igihe yoherejwe kubakiriya.

Umwanzuro:

Igikorwa cyo gukora ifu ya polymer isubirwamo ikubiyemo polymerisation ya monomers kugirango itange polymer ikwirakwizwa, hanyuma ikurikirwa no kumisha spray kugirango ihindurwe muburyo bwifu yumye. Intambwe nyuma yo gutunganya yemeza ibicuruzwa byiza, ituze, hamwe nububiko bwo kubika no gukwirakwiza. Ubu buryo butuma habaho gukora RPP zitandukanye kandi zikora cyane zikoreshwa munganda zitandukanye, zirimo ubwubatsi, amarangi hamwe nudusanduku, ibifatika, hamwe n imyenda.
