Sera imagwiritsidwa ntchito kale ngati zokutira ndi zowonjezera za inki, zomwe zimadziwika ndi kugwiritsa ntchito kosavuta.Pambuyo ❖ kuyanika yomanga, chifukwa volatilization zosungunulira, sera mu ❖ kuyanika precipitates, kupanga makhiristo zabwino, akuyandama padziko ❖ kuyanika filimu, amene amagwira ntchito zosiyanasiyana ntchito bwino ❖ kuyanika filimu.Tsopano, kuwonjezera pa phula la mchere wa polima, sera zachilengedwe sizigwiritsidwa ntchito kawirikawiri mu zokutira ndi inki.M'malo mwake, sera ya polima ndi zotuluka zake zosinthidwa zimagwiritsidwa ntchito.Amatha kupatsa filimuyo kukana kwamadzi bwino, chinyezi ndi kutentha, kukana kukanda, kutha, kuwononga anti, komanso kumva bwino kwa manja.Kukaniza kwawo kungathe kutha kwa mtundu wa pigment.Polypropylene serandi otsika molecular kulemera polypropylene homopolymer kapena copolymer kwambiri ntchito zokutira.

Ntchito yaphula la polypropylenezimadalira zinthu zotsatirazi: zosiyanasiyana ndi specifications polypropylene, fineness wa particles potsiriza anapanga ndi luso kusamukira padziko filimu, komanso zikuchokera ❖ kuyanika, katundu wa TACHIMATA gawo lapansi, zomangamanga ndi ntchito. njira, etc. Zotsatirazi zikufotokoza ntchito yake:
1. Kutha.
Sera zosiyanasiyana zimakhala ndi zotsatira zosiyana pa kung'anima kwa filimuyi: kuchokera kuzimiririka kwambiri mpaka kuwonjezereka kwa gloss ndikupanga mizere yonyezimira yosiyana ndi nyundo.Kumverera: zowonjezera sera zimapangitsa kuti ❖ kuyanika kumveke bwino, zomwe sizingatheke ndi othandizira ena.
2. Valani kukana.
Chimodzi mwazinthu zomwe zimathandizira kuti anti friction ndi anti scratch ndichepetse kugundana kwa malo okutira, kotero kuti chinthucho chikalumikizana ndi zokutira, kutsetsereka kumakhala kwakukulu kuposa kukanda.Pachifukwa ichi, ntchito ya sera ya polypropylene ikufanana ndi mafuta a silicone.Kusiyana ndi kuti wakale alipo pa ❖ kuyanika pamwamba mu mawonekedwe a particles zabwino omwazika.Zochepa zokha zimafunikira kuti mukwaniritse kukana zikande.Sera ya polypropylene, yowonjezeredwa ku zokutira, imatha kuchepetsa kwambiri chizolowezi chopukutira chifukwa cha mikangano, ndikusunga kulimba kwa gloss yotsika, yomwe nthawi zambiri imafunikira pakuyika.Mwachitsanzo, mu alkyd varnish, pamene mlingo wa sera ya polypropylene ndi 1.5%, mtengo wotsutsa-kuvala wa filimuyo umawirikiza kawiri, ndipo pamene mlingo uli 3%, mtengo wotsutsa-kuvala ukuwonjezeka ndi 5 nthawi.Zinthu zachitsulo zikamakhudzana ndi zinthu zokutidwa, nthawi zina zimasiya zikwangwani zakuda pafilimuyo.Kuonjezera sera ya polypropylene mufilimuyi kungachepetse chizolowezi ichi kapena kupangitsa kuti zizindikiro zikhale zosavuta kuzipukuta.Sera yaing'ono ya ufa imagwiritsidwa ntchito posindikiza inki kuti inki ikhale yolimba kwambiri.

3. Anti adhesion.
Zopangira zina, monga matabwa kapena zinthu zowonetsera golidi, nthawi zambiri zimafunika kuunikidwa pakangopita nthawi yochepa mutakutira.Kupita patsogolo kwa umisiri wosindikiza kumafunanso inki kuti apewe kuipitsa zinthu zosindikizidwa.Sera ya polyethylene imatha kupewa kumamatira ndi dothi chifukwa cha kuchulukana kwa zinthu zopangidwa kapena zosindikizira.
4. Anti sedimentation, anti sagging ndi thixotropy.
Kuyika kwa pigment zachitsulo.Sera ya polyethylene yomwazika mu zosungunulira zonunkhira komanso aliphatic imatha kukulitsa kukana kwa mpweya wa zokutira ndi inki.Zimasonyezanso mosiyanasiyana thixotropy, sagging kukana ndi udindo wa zitsulo inki.
Sera ya polyethylene ikhoza kuwonjezeredwa ku zokutira ndi inki m'njira zambiri
(1) Kukula ndi kukula yaying'ono ufa ndi pre omwazika mawonekedwe a polyethylene sera mu zosungunulira, amene ndi yabwino kuwonjezera.Micro powder ndiye mawonekedwe omwe amagwiritsidwa ntchito kwambiri.Mitundu yosiyanasiyana ya ufa wa sera ndi yoyenera zokutira ndi inki zamitundu yosiyanasiyana ndi zofunika.Iwo akhoza kusankhidwa molingana ndi thupi ndi mankhwala ntchito zolozera ndi tinthu kukula kugawa sera.Thupi ndi mankhwala katundu makamaka amanena za katundu wa sera palokha, monga kapangidwe mankhwala, maselo kulemera, malo osungunuka, malowedwe, asidi mtengo, etc.
2) Emulsion ndi kubalalitsidwa odzola ndi khola kupezeka mkhalidwe sera m'madzi, ndi tinthu kukula zambiri zosakwana 1m.Pansi pa 200 nm, nthawi zambiri imakhala yowonekera kapena yowonekera.The tinthu kukula m'munsimu 1m amatchedwa kubalalitsidwa kapena kusiyana kubalalitsidwa.Kubalalitsidwa kwamadzi kumapangitsa kugwiritsa ntchito sera ya polyethylene m'madzi acrylate ndi zokutira za polyurethane ndi inki zosavuta.
