Nigute ushobora guhitamo inyongeramusaruro mumazi ya polyurethane

Nigute ushobora guhitamo inyongeramusaruro muri polyurethane yo mu mazi? Hariho ubwoko bwinshi bwamazi ashingiye kumazi ya polyurethane, kandi urwego rwo gusaba ni rugari, ariko uburyo bwabafasha burigihe. 

01

Guhuza inyongeramusaruro nibicuruzwa nabyo nibintu byambere bigomba kwitabwaho muguhitamo inyongeramusaruro. Mubihe bisanzwe, abafasha nibikoresho basabwa guhuza (bisa mumiterere) kandi bihamye (nta generation nshya yibintu) mubikoresho, bitabaye ibyo biragoye gukina uruhare rwabafasha.

02

Inyongeramusaruro mubikoresho byongeweho igomba gukomeza imikorere yumwimerere yinyongera igihe kirekire idahindutse, kandi ubushobozi bwinyongera kugirango bugumane imikorere yumwimerere mubisabwa byitwa kuramba kwinyongera. Hariho uburyo butatu bwabafasha gutakaza imitungo yumwimerere: guhindagurika (uburemere bwa molekile), gukuramo (solubilité yibitangazamakuru bitandukanye), no kwimuka (solubility ya polymers zitandukanye). Muri icyo gihe, inyongeramusaruro igomba kugira amazi, kurwanya amavuta no kurwanya ibishishwa. 

03

Muburyo bwo gutunganya ibikoresho, inyongeramusaruro ntishobora guhindura imikorere yumwimerere kandi ntabwo izagira ingaruka mbi kubikorwa no gutunganya imashini nibikoresho byubaka.

04

Inyongeramusaruro zikoreshwa muguhuza ibicuruzwa, inyongeramusaruro zigomba kuba zujuje ibisabwa byihariye byibikoresho mugukoresha, cyane cyane uburozi bwinyongera.

05

Kugirango ubone ibisubizo byiza, ikoreshwa ryinyongera rivanze. Iyo uhisemo guhuza, hari ibintu bibiri: kimwe ni uguhuza porogaramu kugirango ubone ibisubizo byiza, naho ubundi ni kubwimpamvu zitandukanye, nko kutaringaniza gusa ahubwo no gusebanya, ntabwo byongeweho urumuri gusa ahubwo na antistatike. Ibi ni ukuzirikana: mubikoresho bimwe bizatanga imikoranire hagati yinyongeramusaruro (ingaruka zose zirenze igiteranyo cyingaruka zo gukoresha inshuro imwe), ingaruka ziyongera (ingaruka zose zingana ningaruka zingaruka zo gukoresha rimwe) na Ingaruka ya antagonistique (ingaruka zose ni munsi yumubare wingaruka zo gukoresha inshuro imwe), igihe cyiza rero cyo kubyara imbaraga, kugirango wirinde ingaruka mbi.

 

Mubikorwa byo kubyara polyurethane ishingiye kumazi kugirango hongerwemo ubwoko runaka bwinyongeramusaruro, birakenewe kwitondera uruhare rwayo mubyiciro bitandukanye byo kubika, kubaka, kubishyira mu bikorwa, no gusuzuma no gusuzuma uruhare n'ingaruka zayo mugice gikurikira. 

Kurugero, iyo irangi rya polyurethane rishingiye kumazi rikoreshejwe hamwe no gusasa no gukwirakwiza ibintu, bigira uruhare runini mububiko no kubaka, kandi nibyiza kumabara ya firime. Mubusanzwe hari ingaruka ziganje, kandi mugihe kimwe zitera urukurikirane rwingaruka nziza icyarimwe, nko gukoresha dioxyde de silicon, hari ingaruka zo kuzimangana, hamwe no kwinjiza amazi, kurwanya anti-adhesion hamwe nizindi ngaruka nziza.

Byongeye kandi, mugukoresha umukozi runaka birashobora kugira ingaruka mbi, nko kongeramo ibikoresho bya silicon birimo defoaming agent, ingaruka zayo zo gusebanya ni ngombwa, birashobora kubona ingaruka nziza, ariko kandi no gusuzuma niba hari umwobo ugabanuka. , ntabwo ari ibicu, ntabwo bigira ingaruka kuri recoating nibindi. Byose muri byose, ikoreshwa ryinyongera ni, mubisesengura ryanyuma, inzira ifatika, kandi igipimo cyonyine cyo gusuzuma kigomba kuba ireme ryibisubizo.
