Nigute ushobora kumenya ubwiza bwifu ya polymer isubirwamo?

mbere. Banza wumve icyo aricyoifu ya polymer isubirwamo.

Ifu ya polymer itatanye ni ifu ya polymers ikozwe muri emulisiyo ya polymer binyuze muburyo bwiza bwo kumisha spray (no guhitamo inyongeramusaruro zibereye). Ifu ya polymer yumye ihinduka emuliyoni iyo ihuye namazi, kandi irashobora kongera kubura umwuma mugihe coagulation no gukomera kwa minisiteri, kuburyo uduce twa polymer tugize imiterere yumubiri wa polymer muri minisiteri, bisa nkibikorwa bya polymer emuliyoni, ishobora guteza imbere sima. ingaruka zishingiye ku mibonano mpuzabitsina. Emulsion yumye ifu yahinduwe yiswe ifu yumye (nanone izwi nka minisiteri yumye ivanze, yumye ivanze). Kubera ko ifu yumye idakeneye gutekereza kumikorere ya emulsiyo no gutuza nka polymer emulisiyo, umubare muto wivanga urashobora gutuma minisiteri igera kubintu byifuzwa, kandi ifite ibyiza byo gupakira byoroshye, kubika, gutwara no gutanga kuruta emulisiyo, antifreeze na oya imikurire yibumba, Ikibazo cya bagiteri nzima, nibyiza ko ishobora gukorwa mubicuruzwa bimwe hamwe nibipfunyika byateguwe nka sima n'umucanga, kandi birashobora gukoreshwa nyuma yo kongeramo amazi.

Iyo usabye, vanga kandi upakire umucanga, sima, emulion yumye yifu nibindi byongeweho byunganira hakiri kare, kandi ukeneye gusa kongeramo amazi runaka mugihe cyo kubaka aho kugirango ifu yumye yumye kandi ikore neza. Intandaro yumusaruro wifu ya emulsiyo yumye nuko ibice bya polymer nyuma yo kugabanura ifu ya latex byerekana ingano yingingo cyangwa ingano yubunini busa nubwa emulioni yumwimerere ya polymer. Umubare munini wa colloid ikingira nka alcool ya polyvinyl igomba kongerwamo emulsiyo, kugirango ifu ya latex ishobore kongera gukwirakwizwa muri emuliyoni iyo ihuye namazi. Gusa hamwe no gutandukana kwiza birashobora guterwa ifu ya latex igera ku ngaruka nziza. . Ifu ya polymer ikwirakwizwa mubisanzwe ni ifu yera. Ibigize birimo:

Polymer resin: Iherereye mubice byibanze byifu ya rubber, kandi nigice cyingenzi cyifu ya polymer isubirwamo.

Inyongera (imbere): hamwe na resin, ikina uruhare rwo guhindura resin. Inyongeramusaruro (hanze): Ibikoresho byongeweho byongeweho kugirango turusheho kwagura imikorere yifu ya polymer itatanye.

Kurinda colloid: urwego rwibikoresho bya hydrophilique bipfunyitse hejuru yifu ya pisitori ya latx isubirwamo, colloid ikingira ifu ya latx isubirwamo cyane ni inzoga ya polyvinyl.

Umuti urwanya keke: wuzuza amabuye y'agaciro meza, ukoreshwa cyane cyane kugirango wirinde ifu ya reberi gutekera mugihe cyo kubika no gutwara no koroshya urujya n'uruza rw'ifu (rujugunywa mu mifuka cyangwa impapuro.)

Uburyo 1, uburyo bwivu

Fata urugero runaka rwifu ya redxersible latex, uyishyire mubikoresho byicyuma nyuma yo gupima, shyushya kugeza kuri dogere 500, nyuma yo gucumura mubushyuhe bwo hejuru bwa dogere 500, ukonje kugeza ubushyuhe bwicyumba, hanyuma wongere upime. Uburemere bworoshye kandi bwiza.

Uburyo bwa kabiri, uburyo bwo gusesa

Fata umubare munini wifu ya redxersible latex hanyuma uyishongeshe inshuro 5 ubwinshi bwamazi, koga neza hanyuma ureke ihagarare muminota 5 mbere yo kureba. Ihame, ibitagabanije bituye murwego rwo hasi, nibyiza ubuziranenge bwifu ya polymer. Ubu buryo buroroshye kandi bworoshye gukora.

Uburyo bwa gatatu, uburyo bwo gukora firime

Fata ubuziranenge bwifu ya latex isubirwamo, uyishongeshe inshuro 2 mumazi, uyunguruze neza, ureke ihagarare muminota 2, ongera uyongere, uyisukemo igisubizo kumirahuri isukuye neza, hanyuma ushire ikirahuri ahantu h'igicucu gihumeka. . Kuraho iyo byumye. Itegereze firime yakuweho. Gukorera mu mucyo no mu bwiza. Noneho gukurura mu buryo bushyize mu gaciro, hamwe na elastique nziza kandi nziza. Iyo firime yaciwemo ibice, yibizwa mu mazi, hanyuma igaragara nyuma yumunsi 1, ubwiza bwa firime ntibwashonga mumazi. Ubu buryo bufite intego
