Uburyo bwo gukora ifu ya polymer ishobora kongera gushonga

Ifu ya polymer ishobora kongera gushonga (RDP)ni ifu itemba neza ikorwa no gusukura polymer ya emulsion. Ikoreshwa cyane mu bikoresho by'ubwubatsi nka mortier yumye, kole y'amatafari, ifu ya putty, kwipima, no gukingira inkuta inyuma. Ikiranga cyayo cy'ingenzi ni ubushobozi bwayo bwo kongera gushonga mu mazi, ikayisubiza muri latex ya polymer ifite imiterere ya emulsion yayo y'umwimerere, bityo igatanga uburyo bwiza bwo gufatana, kworoha, no kudakoresha amazi ku bikoresho. Inzira yo gukora RDP ikubiyemo intambwe nyinshi z'ingenzi, kuva ku guhitamo ibikoresho fatizo kugeza ku gupakira ibicuruzwa byarangiye. Ibi bikurikira bizasobanura neza inzira rusange, ibintu by'ingenzi bya tekiniki, no kugenzura ubuziranenge.

1. Guhitamo ibikoresho fatizo no gutegura Emulsion

Umusaruro wa RDP ushingiye kuri polymer za emulsion. Sisitemu zisanzwe za polymer zirimo vinyl acetate-ethylene copolymer (VAE), acrylic esters, na styrene-acrylic esters. Sisitemu zitandukanye za polymer zigena imikorere ya RDP. Urugero, sisitemu za VAE zitanga ubworoherane bwiza no gufatana, bigatuma zikoreshwa neza mu gufunga amatafari na sisitemu zo gukingira; mu gihe sisitemu za emulsion za acrylic zonyine zitanga ubudahangarwa bw'ikirere no kudahangana n'imirasire ya UV, bigatuma zikoreshwa cyane mu gupfuka inkuta cyangwa gutwikira inyuma.

Emulsions zikunze gutegurwa hakoreshejwe uburyo bwa emulsion polymerization. Hakoreshejwe amazi nk'uburyo bwo gutatanya, emulsifiers, initiators, na control of expansion, monomers zikorerwa polymerization kugira ngo zikore emulsion ya polymer ihamye. Iyi ntambwe isaba kugenzura neza ingano y'uduce, ingano y'ibintu bikomeye, n'ubushyuhe kugira ngo hamenyekane ko umusaruro wa nyuma uhamye kandi utunganye.

2. Uburyo bwo kumisha spray

Nyuma yo gutegura emulsion, ihinduka ifu binyuze mu kumisha spray, ikaba ari intambwe y'ingenzi mu gukora RDP. Intambwe z'iyi gahunda zirimo:

Atomization yo gutera: Emulsion ishyirwamo atome nto cyane hakoreshejwe umunwa w'umuvuduko mwinshi cyangwa atomizer ya centrifugal. Ubusanzwe umurambararo w'amatome ugenzurwa kugeza kuri mikoroni icumi kugira ngo hume neza kandi ifu ihuze neza.

Kumisha umwuka ushyushye: Ibitonyanga bya atome bihura n'umwuka ushyushye ushyushye cyane (hafi 120-180°C), bigahita bihindura amazi umwuka vuba kandi bikamisha uduce twa emulsion mu turemangingo duto. Iyi gahunda isaba ubushyuhe buringaniye n'igihe kugira ngo hirindwe ubushyuhe bukabije bushobora gutuma polymer ishonga cyangwa ibora.

Gusiga hejuru no kuvura uduti: Kubera ko uduce twa polymer dushobora gufatana, colloid irinda, nka polyvinyl alcohol (PVA), ikunze kongerwamo mu gihe cyo kumisha kugira ngo habeho agace karinda. Ibi bibuza ifu gufungana kandi bigafasha kongera gushonga vuba mu mazi.

Gushyira mu byiciro no gukusanya umwuka: Nyuma yo kumisha, ifu irangiye ikusanywa hakoreshejwe agakoresho ko gutandukanya inkubi y'umuyaga n'akayunguruzo k'umufuka kugira ngo hamenyekane ko uduce dukwirakwira neza kandi ikureho umukungugu muto.

3. Igenzura ry'Ubuziranenge n'Impinduka

Igenzura ry'ubuziranenge ni ingenzi mu gikorwa cyose cyo gukora. Ibipimo by'ingenzi by'ibizamini birimo:
Ingano y'uduce duto n'uburyo tworoshye gutemba: Menya neza ko ifu ikwirakwira mu mvange yumye, wirinde ko iterana.
Ubushuhe busigaye: Muri rusange bugenzurwa hagati ya 1% na 2% kugira ngo hirindwe ubushuhe n'iterana ry'ibimera mu gihe cyo kubibika.

Kongera gushonga: Ibi bipima igipimo cy'isukari y'ifu n'ingano y'uturemangingo mu mazi, ibyo bikaba ari ibipimo by'ingenzi byo gusuzuma ubwiza bwa RDP.

Ingufu zo gufata no koroherana: Ibi bigeragezwa binyuze mu igerageza rya sima za mortiweri kugira ngo harebwe ingaruka zabyo mu kunoza imikorere y'ibikoresho by'ubwubatsi.

Hari n'ibindi bicuruzwa bihinduka mu mikorere, nko kongeramo ikintu gitera amazi kudafata neza cyangwa gushyiraho monomer ihindura imiterere kugira ngo yongere ubushobozi bwo kudafata neza imyanda. Izi mpinduka zituma RDP ihura n'ibikenewe mu nyubako zitandukanye.

4. Gupakira no Kubika

Ibikoresho bya RDP bikunze gupakirwa mu mifuka myinshi y’impapuro iriho agapapuro karinda ubushuhe, gafite ingano isanzwe ya kg 20 kuri buri mufuka. Ububiko bugomba kubikwa kure y’ubushuhe n’izuba ryinshi, kandi ubushyuhe bw’ububiko bugomba kuguma hagati ya dogere selisiyusi 5 na 35. Gupakira no kubika neza ni ingenzi kugira ngo RDP ikomeze igihe cyayo cyo kubika (ubusanzwe amezi 12).

Uburyo bwo gukora ifu ya polymer ishobora kongera gushongani ikoranabuhanga risesuye rihuza ikoranabuhanga rya polymer, polymerization ya emulsion, kumisha spray, no gukora ifu. Binyuze mu kugenzura neza ubuziranenge mu gikorwa cyose, harimo guhitamo ibikoresho fatizo, gutegura emulsion, kumisha spray, no kugenzura ubuziranenge, dukora ibicuruzwa bya RDP bifite ubushobozi bwo gukwirakwira no gukoreshwa neza. Ikoreshwa ryayo mu bikoresho by'ubwubatsi bigezweho ntiryongera imikorere y'ubwubatsi gusa ahubwo rinateza imbere iterambere ry'ibikoresho by'ubwubatsi bitujuje ubuziranenge.
