Pambuyo pa zaka zoposa makumi awiri ndi zisanu ndikugwira ntchito ndi zokutira, inki, zomatira, ndi njira zamakampani, Ndaphunzira kuti thovu ndi limodzi mwamavuto omwe nthawi zambiri salandira chisamaliro chomwe chimayenera kuperekedwa mpaka itasiya kupanga.. Chithovu chaching'ono pakusakaniza chikhoza kuwoneka chopanda vuto, koma ikapitirira mpaka ku chinthu chomalizidwa, mukhoza kumaliza ndi pinholes, makola, kusayenda bwino, gloss yafupika, kapenanso magulu okanidwa. Defoamer ndizowonjezera zomwe zimachita mwakachetechete ndi izi, ndipo muzochitika zanga nthawi zambiri amapanga kusiyana pakati pa mzere woyenda bwino ndi kuyatsa moto kosalekeza.
Nkhovu zimapangika pamene mpweya watsekeredwa mumadzimadzi ndipo thovulo limakhazikika ndi zinthu zogwira ntchito pamwamba. Mu utoto ndi zokutira machitidwe, zokhazikikazo nthawi zambiri zimakhala zotulutsa ndi zonyowetsa zomwe zimafunikira kuti ma pigment asakhazikike. Panthawi yobalalika kwambiri kapena kupopera, mpweya wambiri umagwiritsidwa ntchito. Ngati kuwira makoma olimba mokwanira, chithovu sichimaswa chokha. Zomwezo zimachitikanso pakuyeretsa madzi oyipa, zomatira kusakaniza, kapenanso njira zina za chakudya. Yasiyidwa osasankhidwa, amachepetsa mphamvu, zimapanga zovuta zachitetezo pansi, ndipo zimakhudza khalidwe lomaliza.
Defoamer imagwira ntchito posagwirizana pang'ono ndi dongosololi m'njira yoyendetsedwa. Zabwino zambiri zimakhala ndi kupsinjika kochepa kwambiri, kotero iwo anafalikira mofulumira pamwamba pa kuwira. Kamodzi kumeneko, amachotsa zinthu zokhazikika ndikuwonda filimu yamadzimadzi mozungulira kuwirako mpaka kuphulika.. Ma defoamers ambiri amakono alinso ndi tinthu tating'ono ta hydrophobic - silika kapena sera - zomwe zimathandiza kuboola khoma kuchokera mkati.. Cholinga sikungogwetsa thovu lomwe lilipo koma kuti chithovu chatsopano zisapangike panthawi yonseyi.
Pali mabanja angapo akuluakulu, ndipo chilichonse chili ndi malo ake. Mafuta opangira mafuta a mchere amagwiritsidwabe ntchito kwambiri chifukwa ndi othandiza komanso otsika mtengo. Amagwira ntchito bwino m'makina ambiri a solventborne komanso m'madzi, ngakhale nthawi zina amatha kuyambitsa chifunga kapena kukhudza recoatability ngati overdose. Zopangidwa ndi silicone, nthawi zambiri amasinthidwa ma polydimethylsiloxanes, ndizothandiza kwambiri komanso zodziwika bwino pamapangidwe opangidwa ndimadzi ndi mafakitale. Iwo akhoza kugwira ntchito pa mlingo wochepa, koma amafunikira kuyezetsa mosamala chifukwa kuchulukira kapena kusagwirizana kungayambitse maso a nsomba kapena ma craters, makamaka mu zomaliza zowala kwambiri. Mzaka zaposachedwa, Zosankha zopangidwa ndi polima ndi silicone zakhala zofala kwambiri, makamaka kumene zofunikira zachilengedwe kapena zowongolera zimaletsa ma silicones achikhalidwe. Izi nthawi zambiri zimapereka kulinganiza bwino pakati pa magwiridwe antchito ndi kukhudzidwa kochepa pazinthu zina zamakanema.
Kusankha defoamer yoyenera sikophweka ngati kusankha imodzi pamndandanda. Gawo limene thovu limawonekera limapanga kusiyana kwakukulu. Ngati vuto makamaka mu millbase pa pigment akupera, nthawi zambiri umafunika wamphamvu, zambiri kulimbikira mankhwala. Ngati chithovu chikuwonekera pambuyo pake panthawi yotsitsa kapena penti yomalizidwa, chotsitsa chotsitsa pang'ono chomwe chimawonjezeredwa panthawiyo nthawi zambiri chimagwira ntchito bwino. Ndawonapo nthawi zambiri pomwe kugawa kowonjezera - theka pogaya ndi theka pakugwetsa - kunapereka zotsatira zoyera kuposa kuyika chilichonse poyambira..
Kuyesa ndikofunikira ndipo sikungalumphe. Mayeso osavuta ogwedeza mu labu amapereka lingaliro lachangu, koma samaneneratu nthawi zonse zomwe zidzachitike pansi pa chomera kapena panthawi yogwiritsira ntchito ndi roller kapena spray. Cheke chabwino ndikadali kupanga gulu laling'ono loyeserera, igwiritseni ntchito momwe kasitomala angachitire, ndipo yang'anani filimu yowuma pansi pa kuyatsa bwino kwa zolakwika. Ndikofunikiranso kutsimikizira kuti defoamer sikuvulaza gloss, kumamatira, kukhazikika kosungirako, kapena katundu wina uliwonse wofunikira.
Kuchulukitsa ndi chimodzi mwa zolakwika zomwe ndimawona. Kuwonjezera defoamer zambiri sikuthetsa vutoli nthawi zonse ndipo kumatha kupanga zatsopano - zolakwika zapamtunda, kuchepa kwachangu pakapita nthawi, kapena chithovu chochulukirapo nthawi zina. Kuchepetsa mlingo kumasiya nkhaniyo itathetsedwa theka. Mfundo ina yothandiza ndi yogwirizana ndi zolembedwa zonse. Chogulitsa chomwe chimagwira ntchito bwino mu utomoni umodzi chimatha kulephera china chifukwa cha kusiyana kwa polarity kapena phukusi la surfactant lomwe lilipo kale..
Kuchokera pa zomwe zinachitikira, maopareshoni omwe ali ndi zovuta zochepa kwambiri zokhudzana ndi thovu ndi omwe amasankha kusankha kwa defoamer ngati gawo la ntchito yokhazikika m'malo mongoganizira motsatira.. Amasunga zolemba zomwe zimagwira ntchito ndi zida zawo zenizeni ndikuyesanso chilichonse chikasintha. Amasamalanso momwe defoamer imawonjezeredwa ndikusakanikirana - kuwonjezera mwachangu popanda kusokonezeka koyenera kumatha kupanga thovu lochulukirapo poyamba..
Pomaliza pake, defoamer wabwino amachita zambiri kuposa kungochotsa thovu. Zimathandiza kuti kupanga kukhale kosasintha, amachepetsa zinyalala, ndikusintha mawonekedwe omaliza a chinthucho. Pamene china chirichonse mu chiphunzitso chikugwira ntchito bwino koma filimuyo imasonyezabe zolakwika, defoamer nthawi zambiri ndi chidutswa chomwe chimafunika kusintha. Palibe chinthu chimodzi chomwe chimathetsa vuto lililonse la thovu, chifukwa chake kuyezetsa kothandiza ndi zokumana nazo zikadali zofunika kwambiri kuposa malingaliro aliwonse ogulitsa okha. Pamene defoamer yoyenera ili pamalo oyenera pa mlingo woyenera, anthu ambiri samazindikira nkomwe kuti ilipo - ndipo ndi momwe ziyenera kukhalira.
