Ndi chitukuko cha chuma cha msika, mpikisano wamalonda ukukula kwambiri.Pomwe akupanga zinthu zabwino, mabizinesi amawonjezera ntchito zofananira zazinthu ndikuyesetsa kupanga zatsopano, zachilendo komanso kukongola.Yakhala njira yatsopano ya mpikisano wazinthu.Mafuta apulasitiki onunkhira ndi amodzi mwa iwo.
Ndiko kuwonjezerazonunkhirapomanga ndi kukonza zinthu, kuti pulasitiki ndi zinthu zina zitha kutulutsa fungo lonunkhira zikagwiritsidwa ntchito, zimapatsa anthu kumverera mwatsopano, momasuka komanso mwatsopano, ndikubisa fungo lachilendo lomwe limapezeka mu utomoni kapena wopangidwa pokonza.Kuchulukitsa mtengo wogwiritsa ntchito zinthu zapulasitiki kumatha kulimbikitsa chikhumbo cha makasitomala kugula, kuti akwaniritse cholinga chopambana modzidzimutsa pampikisano wowopsa wamsika.
Aromatic masterbatch ndi chisakanizo chokhala ndi mankhwala onunkhira ochuluka omwe amamwazikana mu thermoplastic resin base base.Mapulasitiki owongolera bwino kwambiri amapangidwa makamaka ndi utomoni wonyamulira, chowonjezera kukoma ndi zowonjezera.Kupyolera mu ukadaulo wina waukadaulo ndi kukonza, kukoma kwake kumamwazikana m'mapulasitiki onyamula.Pulasitiki ndi ma polima apamwamba kwambiri okhala ndi kulemera kwakukulu kwa mamolekyu komanso malo otalikirana ndi ma cell.M'maselo a mapulasitiki, pali zigawo za kristalo zomwe zimakhala ndi mamolekyu nthawi zonse, madera amorphous omwe ali ndi dongosolo losalongosoka, ndipo ena ali ndi magulu a polar, omwe amathandiza kuti alowetse zigawo zogwira mtima za zowonjezera zokoma mu mamolekyu apulasitiki pogwiritsa ntchito njira zakuthupi kapena zamankhwala kupanga multiphase ndi dongosolo lapafupi pakati pa zokometsera zowonjezera ndi ma polima.Chifukwa permeability ndi kusakhazikika kwa otsika maselo zinthu, Ndipo ngakhale, kutizonunkhiramu pulasitiki mosalekeza diffuses kuchokera mkulu ndende otsika ndende, ndiyeno volatilizes kuchokera pamwamba ku chilengedwe, limatulutsa fungo lonunkhira, kuti akwaniritse cholinga cha nthawi yaitali fungo kubalalitsidwa.
zonunkhirandiye chigawo chachikulu cha onunkhira pulasitiki masterbatch.Ndi chinthu chonunkhira chomwe chimagwiritsidwa ntchito kuonjezera kapena kukonza fungo la zinthu.Malinga ndi kapangidwe kake, imatha kugawidwa m'ma esters, ma alcohols, aldehydes ndi carboxylic acid.Chifukwa cha mitundu yosiyanasiyana, kukana kutentha ndi kugwirizana ndi utomoni kumasiyananso.The processing ndi akamaumba kutentha resins wamba ndi pamwamba 150 ° C. Choncho, ayenera kusankhidwa ndi kukana bwino kutentha, osati zosavuta kuchita ndi utomoni ndi zina zowonjezera, mlingo wochepa, palibe kawopsedwe, ndi kuyanjana kwina ndi utomoni m'munsi.
