Imikoreshereze
Pentaerythritol ikoreshwa cyane cyane mu nganda zikora irangi. Ishobora gukoreshwa mu gukora irangi rya alkyd resin, rishobora kunoza ubukana, ububengerane n'ubudahangarwa bwa firime ikora irangi. Ikoreshwa kandi nk'ibikoresho fatizo bya rosin esters zikenewe mu irangi, varnish na wino zicapa, kandi ishobora gukoreshwa mu gukora amavuta yumisha, irangi rifumba n'amavuta yo mu kirere. Byongeye kandi, ikoreshwa no mu gukora imiti, imiti yica udukoko n'ibindi bicuruzwa. Molekile ya pentaerythritol irimo amatsinda ane ya hydroxymethyl angana kandi ifite urwego rwo hejuru rw'ubusumbane. Kubwibyo, ikunze gukoreshwa nk'ibikoresho fatizo mu gutegura imvange y'ibintu bifatika. Nitrification yayo ishobora gukora pentaerythritol tetranitrate, ikaba ari iturika rikomeye; esterification ishobora kubona pentaerythritol triacrylate, ikoreshwa nk'irangi. Ishobora kandi gukoreshwa nk'itangiza umuriro ku biti. Iyo ihujwe na ammonium polyphosphate, haboneka itarangiza umuriro rishobora kuboneka. Ikoreshwa kandi nk'igikoresho gihuza polyurethane kugira ngo itange iminyururu y'amashami muri polyurethane.
Gupakira no Kohereza
Gupakira: 25/kg,Amapaki apfunyitse muri pulasitiki cyangwa amasakoshi y'impapuro z'ubudodo cyangwa hakurikijwe ibyo umukiriya akeneye.
Kohereza: ni imiti isanzwe kandi ishobora gutangwa hakoreshejwe gari ya moshi, inyanja n'ikirere.
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
