Ifu ya polymer isubirwamo (RDPs) igira uruhare runini mubikorwa bitandukanye, harimo ubwubatsi, ibifata, hamwe nububiko.Iyi fu ikoreshwa cyane mugutezimbere ibikoresho bya sima, kongera imbaraga, guhinduka, no kuramba.Gusobanukirwa inzira yumusaruro wa RDP ningirakamaro kubabikora kugirango ibicuruzwa byujuje ubuziranenge.
Ibikoresho bibisi:
Umusaruro wifu ya polymer isubirwamo utangirana no guhitamo neza ibikoresho fatizo bigira ingaruka kumiterere yibicuruzwa byanyuma.Ibice byibanze birimo polymer resin, colloide ikingira, plasitike, ninyongeramusaruro zitandukanye.
Polymer Resins: Ethylene-vinyl acetate (EVA), vinyl acetate-Ethylene (VAE), hamwe na polymers ya acrylic bikoreshwa cyane nkibikoresho bya polymer nyamukuru.Ibisigarira bitanga guhuza, guhinduka, no kurwanya amazi kuri RDPs.
Kurinda ibiyobya bwenge: Hydrophilic irinda colloide nka alcool ya polyvinyl (PVA) cyangwa ethers ya selile yongeweho kugirango ihagarike ibice bya polymer mugihe cyo kumisha no kubika, birinda guteranya.
Plastiseri: Plastiseri itezimbere imiterere n'imikorere ya RDPs.Amashanyarazi asanzwe arimo glycol ethers cyangwa polyethylene glycol.
Inyongeramusaruro: Inyongeramusaruro zitandukanye nko gutatanya, kubyimbye, hamwe no guhuza ibikorwa bishobora gushyirwaho kugirango byongere imitungo yihariye nko gutandukana, imvugo, cyangwa imbaraga za mashini.
Uburyo bwo gutunganya:
Gukora ifu ya polymer isubirwamo ikubiyemo intambwe nyinshi zitoroshye zo gutunganya, harimo na emulion polymerisation, kumisha spray, hamwe nuburyo bwo kuvura.
Emulsion Polymerisation:
Inzira itangirana na emulion polymerisation, aho monomers, amazi, emulisiferi, hamwe nababitangije bivangwa mumashanyarazi mugihe cyubushyuhe nubushyuhe.Monomers polymerize kugirango ibe latex ibice bitatanye mumazi.Guhitamo ba monomers nibisubizo byerekana polymer yibigize hamwe nimiterere.
Gutuza no Kwishyira hamwe:
Nyuma ya polymerisiyonike, latex ihura noguhindura wongeyeho colloide ikingira hamwe na stabilisateur.Iyi ntambwe irinda uduce duto duto kandi ikanemeza ituze rya latex.Ibikoresho bya coagulation birashobora gutangizwa kugirango bitume coagulation igenzurwa nuduce duto twa latx, ikora coagulum ihamye.
Gusasira Kuma:
Ikwirakwizwa rya latex itajegajega noneho igaburirwa mumashanyarazi.Mu cyumba cyo kumisha spray, gutatanya byinjijwe mu bitonyanga bito ukoresheje umuvuduko mwinshi.Umwuka ushyushye utangirwa icyarimwe kugirango uhumeke amazi, hasigare uduce duto twa polymer.Imiterere yumye, harimo ubushyuhe bwikirere bwinjira, igihe cyo gutura, nigipimo cyumuyaga, bigira ingaruka kumiterere ya morphologie hamwe nifu yifu.
Nyuma yo kuvurwa:
Nyuma yo kumisha spray, ifu ya polymer yavuyemo ikora nyuma yubuvuzi kugirango itezimbere imikorere nububiko buhamye.Izi nzira zishobora kubamo guhindura isura, granulation, hamwe no gupakira.
a.Guhindura Ubuso: Ibikoresho bikora hejuru cyangwa guhuza ibikorwa bishobora gukoreshwa kugirango uhindure imiterere yubuso bwa polymer, byongerera imbaraga no guhuza nibindi bikoresho.
b.Granulation: Kunoza imikorere no gutatana, ifu ya polymer irashobora gukorerwa granulation kugirango itange ingano nini kandi igabanye ivumbi.
c.Gupakira: RDPs zanyuma zapakiwe mubintu bidashobora kwihanganira ubushuhe kugirango birinde kwangirika no gukomeza guhagarara neza mugihe cyo kubika no gutwara.
Ingamba zo kugenzura ubuziranenge:
Kugenzura ubuziranenge nibyingenzi mubikorwa byose kugirango habeho guhuza no kwizerwa mumiterere yifu ya polymer.Ibice byinshi byingenzi bikurikiranwa kandi bigenzurwa mubyiciro bitandukanye:
Ubwiza bwibikoresho fatizo: Kugenzura neza no kugerageza ibikoresho fatizo, harimo polymers, colloide, ninyongeramusaruro, bikorwa kugirango hamenyekane ubwiza bwabyo, ubuziranenge, hamwe nibihuza nibisabwa.
Gukurikirana Ibikorwa: Ibipimo byingenzi byubushyuhe nkubushyuhe bwa reaction, umuvuduko, igipimo cyibiryo bya monomer, hamwe nuburyo bwumye bikurikiranwa kandi bigahinduka kugirango ibicuruzwa bibe byiza kandi bihamye.
Ibiranga Ibice: Gukwirakwiza ingano yubunini, morphologie, hamwe nubuso bwimiterere ya puderi ya polymer isesengurwa hakoreshejwe tekinike nka diffaction ya laser, microscopi electron, hamwe nisesengura ryubutaka.
Kwipimisha Imikorere: Ifu ya polymer isubirwamo ikorerwa ibizamini byinshi kugirango isuzume imbaraga zifatika, imiterere ya firime, kurwanya amazi, hamwe nubukanishi ukurikije amahame yinganda nibisabwa nabakiriya.
Ikizamini gihamye: Byihuse ibizamini byo gusaza hamwe nubushakashatsi buhamye bukorwa kugirango harebwe igihe kirekire RDPs ihagaze neza mububiko butandukanye, harimo ubushyuhe nubushyuhe butandukanye.
Umusaruro wifu ya polymer isubirwamo urimo urukurikirane rwintambwe, kuva emulion polymerisation kugeza gutera kumisha hamwe na nyuma yubuvuzi.Mugucunga neza ibikoresho fatizo, ibipimo byo gutunganya, hamwe ningamba zo kugenzura ubuziranenge, ababikora barashobora kwemeza ubuziranenge n’imikorere ya RDPs kubikorwa bitandukanye mubikorwa byubwubatsi, ibifata, hamwe ninganda.Gusobanukirwa nubuhanga bwibikorwa byumusaruro ningirakamaro mugutezimbere ibicuruzwa no guhuza ibikenerwa byabakiriya ku isoko.
