Dibutyl phthalate (DBP)
Dibutyl phthalate ni pulasitiki ifite ubushobozi bwo gushonga cyane kuri pulasitiki nyinshi. Ikoreshwa mu gutunganya PVC, ishobora gutuma ibicuruzwa byoroha neza. Ishobora kandi gukoreshwa mu gupfuka nitrocellulose. Ifite ubushobozi bwo gushonga neza, gushonga neza, gufatana no kudakoresha amazi. Ishobora kandi kongera ubushobozi bwo gushonga, kudahinduka, kudahinduka, no gukora neza kwa pulasitiki. Ifite ubushobozi bwo guhuza neza kandi ni pulasitiki ikoreshwa cyane ku isoko. Ikwiriye amabara atandukanye, cellulose butyl acetate, ethyl cellulose polyacetate, vinyl ester n'izindi resins zikoze nk'ipulasitiki. Ishobora kandi gukoreshwa mu gukora irangi, ibikoresho byo kwandikamo, uruhu rw'ubukorano, wino icapa, ikirahure cy'umutekano, cellophane, lisansi, imiti yica udukoko, impumuro nziza, amavuta yo kwisiga n'imashini yoroshya imyenda, n'ibindi.

Porogaramu
Ikoreshwa nk'inyongera mu gusiga irangi riva mu mazi kugira ngo yihutishe ikorwa rya firime
Imikorere
Inyongeramusaruro zikora filime, pulasitiki, ntizihumanya kandi ntiziryoha
1. Ibisobanuro:
Muri rusange, emulsion igira ubushyuhe butuma ikora firime, Iyo ubushyuhe buri hasi y’ubushyuhe butuma ikora firime ya emulsion, firime ya emulsion irashobora kunoza imashini ikora firime ya emulsion no gufasha gukora firime. Nyuma yo gukora firime, firime ikora firime irahindagurika, ibyo ntibizagira ingaruka ku miterere ya firime. Iyi firime ifite ubushyuhe bwinshi, imikorere myiza mu bidukikije, ihindagurika neza, kandi byoroshye kuyinjizamo uduce twa latex. Ishobora gukora firime nziza ikomeza. Ni ibikoresho bikora firime bifite imikorere myiza mu irangi rya latex, bishobora kunoza cyane imikorere ya latex. Ntabwo ikora gusa kuri acrylic, styrene-acrylic, acrylic acetate emulsion, ahubwo inakora no kuri vinyl acetate emulsion. Uretse kugabanya cyane ubushyuhe buke bw’irangi rya latex, ishobora no kunoza uburyo ikora, kurwanya ikirere, kurwanya gukaraba no gukura kw’amabara y’irangi rya latex, kugira ngo firime igire uburyo bwiza bwo kubika.
2. Ahantu ho gushyiramo porogaramu:
A. Gusiga irangi mu nyubako, gusiga irangi mu modoka nziza no gusana, gusiga irangi rizunguruka
B. Umusemburo w'imyenda ukoresha uburyo bwo gucapa no gusiga irangi mu buryo butangiza ibidukikije
C, ikoreshwa mu gukora wino, ikoreshwa mu gukuraho irangi, kole, ikoreshwa mu gusukura n'izindi nganda
3. Kubika no gupfunyika:
A. Emulsions/inyongeramusaruro zose zishingiye ku mazi kandi nta ngaruka zo guturika iyo zitwarwa.
B. 200 kg/icyuma/ingofero ya pulasitiki. 1000 kg/ipaki.
C. Gupfunyika byoroshye bikwiranye n'agasanduku ka metero 20 ni amahitamo.
D. Iki gicuruzwa kigomba kubikwa ahantu hakonje kandi humutse, hirindwa ubushuhe n'imvura. Ubushyuhe bwo kubikwa ni 5 ~ 40℃, kandi igihe cyo kubikwa ni amezi agera kuri 24.
