Mu gihe cyo gutunganya no gukoresha filime za pulasitiki, kugira ngo hongerwe imiterere ya resin cyangwa filime zimwe na zimwe zidahuye n'ibisabwa mu ikoranabuhanga ryazo ryo gutunganya, ni ngombwa kongeramo inyongera za pulasitiki zishobora guhindura imiterere yazo kugira ngo zihindure imikorere y'umusaruro. Nk'imwe mu nyongera zikenewe kuri filime ishyushye, hepfo hari uburyo burambuye bwo gushyiraho icyuma gikingira pulasitiki. Hariho ibintu bitatu bikunze gukoreshwa mu kurwanya slippery agent: oleic amide, erucamide, silicon dioxide; Uretse inyongera, hari n'inyongera zikora nka masterbatches zifunguye na masterbatches ziroroshye.
1. Umuti utemba
Kongeramo ikintu cyoroshye mu gupfunyika nko kongeramo urwego rw'amazi hagati y'ibirahure bibiri, bigatuma gupfunyika kwa plastiki byoroha gupfunyika ibirahure bibiri ariko bikagorana kubitandukanya.
2. Ikoreshwa mu gufungura umunwa
Kongeramo agakoresho ko gufungura cyangwa gukoresha masterbatch kuri firime nko gukoresha sandpaper kugira ngo uhindure ubuso hagati y'ibirahuri bibiri, ku buryo byoroshye gutandukanya ibice bibiri bya firime, ariko bigoye kuyinyerera.
3. Fungura masterbatch
Ibikubiye muri iyo mvange ni silika (inorganic)
4. Masterbatch yoroshye
Ibikoresho: amide (organic). Shyiramo amide n'umuti urwanya impanuka muri masterbatch kugira ngo bibe ingano ya 20-30%.
5. Guhitamo umukozi ufungura
Muri masterbatch ifunguye neza, guhitamo amide na silica ni ingenzi cyane. Ubwiza bwa amide ntibungana, bigatuma masterbatch igira ingaruka ku ruhu rimwe na rimwe, nko kuryoha gukomeye, utudomo tw'umukara nibindi, byose biterwa n'umwanda mwinshi n'ingano y'amavuta y'inyamaswa yanduye. Mu guhitamo, bigomba kugenwa hakurikijwe isuzuma ry'imikorere n'ikoreshwa rya amide. Guhitamo silica ni ingenzi cyane, kandi bigomba gusuzumwa mu bintu byinshi nko mu bunini bw'uduce, ubuso bwihariye, ingano y'amazi, gutunganya ubuso, nibindi, bigira ingaruka zikomeye ku ikorwa rya masterbatch no mu nzira yo kurekura filime.
