Itandukaniro hagati yamazi ashingiye kuri Polyurethane hamwe namavuta ashingiye kuri Polyurethane
Amazi ashingiye ku mazi ya polyurethane adasukuye amazi ni ibidukikije byangiza ibidukikije cyane-polymer polymer elastique idafite amazi kandi bifata neza kandi bidashoboka. Ifite neza neza isima ishingiye kuri sima nka beto n'amabuye n'ibicuruzwa. Igicuruzwa gifite imiti ihamye kandi irashobora kwihanganira igihe kirekire cyizuba. Ifite ibiranga elastique nziza no kuramba.
Ibiranga ibicuruzwa
1. Kugaragara: Igicuruzwa kigomba kuba kitarimo ibibyimba nyuma yo gukurura no muburyo bumwe.
2. Ifite imbaraga zingana cyane, kuramba cyane, elastique nziza, imikorere myiza mubushyuhe bwo hejuru kandi buke, hamwe no guhuza neza no kugabanuka, guturika, no guhindura imiterere ya substrate.
3. Kwizirika kwayo nibyiza, kandi nta primaire isabwa kuri substrate zitandukanye zujuje ibisabwa.
4. Igifuniko cyumye kandi kigakora firime nyuma yacyo irwanya amazi, irwanya ruswa, irwanya ifu, kandi irwanya umunaniro.
5. Imikorere y’ibidukikije ni nziza, kuko idafite ibice bya benzene cyangwa amakara y’amakara, kandi nta yandi mashanyarazi asabwa mu gihe cyo kubaka.
6. Nibintu bimwe, ibicuruzwa bikonje bikoreshwa byoroshye gukoresha no kubishyira mubikorwa.
Ingano yo gusaba ibicuruzwa
1. Bikwiranye n'ibyumba byo munsi y'ubutaka, parikingi yo munsi y'ubutaka, metero zaciwe na metero
2. Igikoni, ubwiherero, ibisate hasi, balkoni, ibisenge bitagaragara.
3. Kwirinda amazi neza no kwirinda amazi yinguni, ingingo nibindi bisobanuro byiza, hamwe no gufunga ingingo zidafite amazi.
4. Kurinda amazi kubidendezi byo koga, amasoko yubukorikori, ibigega byamazi, hamwe numuyoboro wo kuhira.
5. Kwirinda amazi kuri parikingi no hejuru yinzu.
Amavuta ashingiye ku mavuta ya polyurethane atagira amazi ni marekile yo hejuru yamazi adafite amazi yumye kandi akomera hejuru. Ikozwe muri isocyanates na polyole nkibikoresho byingenzi, hamwe nibikoresho bitandukanye byingirakamaro nko kuvanga ibyuma byihishe hamwe na plasitike, kandi bikozwe nuburyo bwihariye bwo kubura ubushyuhe bwo hejuru hamwe na polymerisiyasi. Iyo ikoreshejwe, ikoreshwa kuri substrate idafite amazi, hanyuma firime ikomeye, yoroheje kandi idafite kashe ya polyurethane itagira amazi ikorwa hejuru yubutaka hamwe nubushakashatsi bwimiti hagati yitsinda rya -NCO ryanyuma rya polyurethane prepolymer nubushuhe bwikirere.
Ibiranga ibicuruzwa
1. Kugaragara: Igicuruzwa numubiri umwe wijimye utagira gel hamwe nibibyimba.
2. Igice kimwe, cyiteguye gukoreshwa kurubuga, kubaka imbeho, byoroshye gukoresha, kandi nibisabwa kubushuhe bwa substrate ntabwo bikomeye.
3. Gufatanya gukomeye: Kwizirika neza kuri beto, minisiteri, ububumbyi, plasta, ibiti, nibindi bikoresho byubaka, guhuza neza no kugabanuka, guturika no guhindura substrate.
4. Firime idafite kashe: Gufatanya neza, nta mpamvu yo gukoresha primer kuri substrate zitandukanye zujuje ibisabwa.
5. Imbaraga zingana za firime, igipimo kinini cyo kuramba, elastique nziza, guhuza neza no kugabanuka no guhindura imiterere ya substrate.
6. Kurwanya imiti, kurwanya ubushyuhe buke, kurwanya gusaza, kurwanya ibumba, gukora neza bitarimo amazi. Ingano yo gusaba ibicuruzwa
Amavuta ashingiye ku mavuta ya polyurethane arashobora gukoreshwa mu kubaka amazi y’inyubako nshya kandi zishaje, ibisenge, hasi, ubwiherero, ibidengeri byo koga, imishinga yo kurengera abaturage, n'ibindi.
Itandukaniro hagati ya polyurethane ishingiye kumavuta na polyurethane ishingiye kumazi:
Polyurethane ishingiye ku mavuta ifite ibintu byinshi bikomeye kuruta polyurethane ishingiye ku mazi, ariko ikozwe muri isocyanate, polyether, hamwe n’ibikoresho bitandukanye bifasha nka miti ivanze yihishe hamwe na plasitike, byateguwe nuburyo budasanzwe ku bushyuhe bwinshi, nko kuvanaho amazi na polymerisation reaction. Ifite umwanda mwinshi, ugereranije na polyurethane ishingiye ku mazi, ikaba ari icyatsi kibisi kandi cyangiza ibidukikije nta mwanda. Irakwiriye gukoreshwa mu nzu, nk'igikoni n'ubwiherero.
