Kupukutira msomali kwanthawi yayitali: ndi iti yomwe mungasankhe? Kanema
Kupukuta misomali, ndipo nthawi zambiri izi ndi momwe enamel ya pigment imatchedwa lero, mwinamwake, mkazi aliyense ali nawo. Wina amagwiritsa ntchito ma varnish owala, wina amakonda mitundu ya pastel, ndipo ena amagwiritsa ntchito ma varnish kuti alimbikitse misomali. Komabe, mosasamala kanthu za zolinga zawo, amayi amafuna kukhala ndi ma varnish apamwamba komanso olimba.
Kusankha msomali wabwino popanda chidziwitso cha chemistry sikophweka.
Varnish yabwino iyenera kukhala:
- dibutyl phthalate (mafuta a castor)
- kutulutsa magazi
- mowa wa butyl
- utomoni wopangidwa bwino
Mafuta a Castor, kapena dibutyl phthalate, ndi ma plasticizers omwe amalola varnish kutambasula ndikukhazikika. Amakhalanso ndi udindo wamakhalidwe amphamvu, chifukwa, pochita ndi ma resins, amapereka mlingo wofunikira wa adhesion (kuthekera kumamatira ku msomali). Akalimba, utomoniwo umapanga filimu yolimba yomwe ingakhale yolimba kwambiri komanso yosasunthika popanda mapulasitiki.
Nitrocellulose imayambitsanso mphamvu ndi kukana kwa varnish yowuma ku kuwonongeka kwa makina - polima yomwe, mwa zina, imapatsa ma varnish ndi gloss yokongola.
Ma butyl kapena ethyl alcohol ndi ocheperako omwe amakwaniritsa kusasunthika kwa ma varnishi. Ndizofunikira kudziwa kuti ngati muthira mowa mu vanishi yomwe yakonzeka kale kugwiritsidwa ntchito (ndiko kuti, yomwe ili ndi zigawo zonse), sikutheka kusungunula kapangidwe kake. Mowa umagwiritsidwa ntchito pamlingo wina wopangidwa; amawonjezeredwa ku kapangidwe ka nitrocellulose.
Zokwera mtengo sizikutanthauza khalidwe lapamwamba
Varnish yapamwamba sikuti ndiyokwera mtengo. Zigawo zomwe tafotokozazi zili ndi mtengo wotsika kwambiri, choncho kupanga ma varnish ndi bizinesi yopindulitsa yomwe sizinthu zamtengo wapatali, koma kuzindikira kwamtundu kumagwira ntchito yofunika kwambiri.
Musanapereke ndalama zogulira, yesani varnish: masulani kapu ya burashi ndikuyikweza pakhosi la thovu, ngati varnish itambasula kumbuyo kwa burashi, "imasewera", kukana kugula, popanga dimethyl ketone. amagwiritsidwa ntchito mopitirira muyeso - zosungunulira acetone.
Mu varnish yabwino, dontho lidzagwa kuchokera ku burashi, muyenera kusamala kuti zidzatenga nthawi yayitali bwanji. Ngati dontho likuyenda pansi nthawi yomweyo, zikutanthauza kuti varnish ndi madzi, chophimba pa msomali chidzakhala chosauka, ndi mikwingwirima. Ngati dontho limatenga masekondi 3-5, varnish ikhoza kugulidwa. Ngati dontho likuchedwa pa burashi, mawonekedwe ake mwina ayamba kale kuwuma. Mwa njira, ma varnish sayenera kuwuma m'masitolo, chifukwa popanga amadzaza m'njira yoti mpweya usalowe mu mpukutuwo.
Ngati mumapatsidwa varnish yokhuthala m'sitolo, dziwani: mwinamwake, zolembazo zakhala zikugwiritsidwa ntchito kale pamaso panu
Yesani kuyika enamel ku misomali yanu: varnish yapamwamba iyenera kukhala yolimba komanso yofanana kuyambira "kuthamanga" koyamba. Onetsetsani kuti mumagwiritsa ntchito gawo lachiwiri ndi lachitatu, varnish yotsika kwambiri iyamba kutuluka, ziphuphu pamtambo wa msomali.
Chifukwa chake, varnish wapamwamba komanso wolimba:
- zodzaza bwino
- ali ndi kufanana kwofananira
- molingana ndi wandiweyani lagona pa msomali
- sichikugudubuza ndi kufalikira
- amapanga filimu yamitundu yofanana
