Mawu oyamba:Zovala zokutira zokutira zomata, zomwe zimadziwikanso kuti zokutira zomatira, ndi mtundu wa polima wokutidwa mofanana pamwamba pa nsalu.Zimapanga filimu imodzi kapena zingapo pamwamba pa nsalu pogwiritsa ntchito adhesion, zomwe sizingangowonjezera maonekedwe ndi mawonekedwe a nsalu, komanso kuwonjezera ntchito ya nsalu, kotero kuti nsaluyo imakhala ndi ntchito zapadera monga kukana madzi. , kukana kuthamanga kwa madzi, mpweya wabwino ndi kutsekemera kwa chinyezi, kuchedwa kwa lawi ndi kuteteza kuipitsidwa, kuteteza kuwala ndi kusinkhasinkha.
Mbiri yachitukuko
Zaka zoposa 2000 zapitazo
Kale ku China, zomatira zomatira zinali kale kugwiritsidwa ntchito pamwamba pa nsalu.Panthawiyo, anali makamaka mankhwala achilengedwe monga lacquer ndi mafuta a tung, omwe ankagwiritsidwa ntchito makamaka popanga nsalu zopanda madzi.
zamakono
Zomatira zomatira za polima zosiyanasiyana zopanga zokhala ndi ntchito yabwino zatulukira.Chopangidwa choyambiriracho chinali ndi vuto loti zisalowe madzi koma osalowa chinyezi.Nsalu yophimbidwayo inkamveka yotsekera komanso yotentha ikagwiritsidwa ntchito, ndipo chitonthozo chake sichinali bwino.
Kuyambira 1970s
Ochita kafukufuku apanga zomatira zomatira zopanda madzi ndi chinyezi zomwe zimatha kulowa munsalu posintha kapangidwe kake kazinthu zomatira ndikusintha njira zopangira zokutira.
Mzaka zaposachedwa
Zomatira zomata zogwirira ntchito ndi zomatira zomata zophatikizika zapita patsogolo kwambiri
Kugawa ndi kapangidwe ka mankhwala
1. Polyacrylate (PA):
Imadziwikanso kuti zokutira zomatira za AC, ndiye zokutira zodziwika bwino komanso zodziwika bwino pakadali pano.Pambuyo zokutira, zimatha kuwonjezera kumverera kwa manja, mphepo yamkuntho ndi kugwedezeka.
PA zomatira zoyera zoyera, ndiko kuti, kuvala utomoni wonyezimira wa acrylic pamwamba pa nsaluyo, kumatha kuwonjezera kuphimba kwa nsalu, kupangitsa kuti ikhale yowoneka bwino, ndikupangitsa kuti utoto wa nsalu ukhale wowala kwambiri.
PA siliva guluu ❖ kuyanika, ndiko kuti, wosanjikiza siliva guluu woyera yokutidwa pamwamba pa nsalu, kotero kuti nsalu ali ndi ntchito yoteteza kuwala ndi ma radiation.Nthawi zambiri amagwiritsidwa ntchito ngati makatani, mahema ndi zovala.
2. Polyurethane (PU):
Pambuyo pakupaka, nsaluyo imamva kuti imakhala yochuluka komanso yotanuka, ndipo pamwamba pake imakhala ndi filimu.
Pu white glue wokutira, ndiye kuti, utomoni woyera wa polyurethane umakutidwa pamwamba pa nsaluyo, ndipo ntchito yake imakhala yofanana ndi ya guluu wa PA woyera, koma zokutira zomatira za Pu zoyera zimamveka bwino, zimamveka bwino. ndi kufulumira kwabwinoko.
Pu silver guluu ❖ kuyanika ali ndi ntchito yofanana ndi PA siliva glue.Komabe, nsalu ya siliva ya Pu imakhala ndi kukhazikika bwino komanso kufulumira.Kwa mahema ndi nsalu zina zomwe zimafuna kuthamanga kwamadzi kwambiri, nsalu ya siliva ya Pu ndi yabwino kuposa nsalu ya siliva ya PA.
3.Polyvinyl chloride (PVC):
Amapangidwa ndi nsalu ya galasi fiber, galasi thonje nsalu ndi mankhwala CHIKWANGWANI nsalu ndi yokutidwa ndi ndondomeko yapadera.Zochita zake zazikuluzikulu ndizo: kusalowa madzi, kuletsa moto, kutsimikizira mildew, umboni wozizira komanso umboni wa dzimbiri (zomwe zimatchedwa "nsalu zotsimikizira katatu" ndi "nsalu zotsimikizira zisanu");Kukana kukalamba;Chitetezo cha UV;Zosavuta kuyeretsa;Kukana kutentha kwakukulu (180 ℃) ndi kutchinjiriza kwabwino kwamafuta.
4. Silicone:
Silicone high elasticity coating, yomwe imadziwikanso kuti kupaka mapepala.Thonje woonda ndi woyenera kwambiri kupanga nsalu ya malaya.Imamveka yodzaza, yofewa komanso yotanuka, yokhala ndi mphamvu zolimba komanso kukana makwinya.Kwa nsalu zowirira, zimakhala ndi elasticity komanso kufulumira.
5. Rabara yopangira (monga neoprene).
Kuphatikiza apo, pali polytetrafluoroethylene, polyamide, polyester, polyethylene, polypropylene ndi mapuloteni.
Pakali pano, polyacrylates ndi polyurethanes amagwiritsidwa ntchito makamaka.
