zinthu

katundu wa mankhwala

Malinga ndi kapangidwe ka mankhwala osiyanasiyana, mtundu uwu wa mankhwala oyezera uli ndi magulu atatu akuluakulu: acrylic acid, organic silicon ndi fluorocarbon. Mankhwala oyezera ndi mankhwala othandizira omwe amagwiritsidwa ntchito kwambiri, omwe angapangitse kuti chophimbacho chikhale chosalala, chosalala komanso chofanana panthawi youma. Amachepetsa bwino kupsinjika kwa pamwamba pa madzi oyezera, kusintha kusinthasintha kwake ndi kufanana kwa gulu la zinthu. Angathandize kupititsa patsogolo kulowetsedwa kwa yankho lomaliza, kuchepetsa kuthekera kwa mawanga ndi zizindikiro potsuka, kuwonjezera kuphimba, ndikupanga filimuyo kukhala yofanana komanso yachilengedwe. Makamaka ma surfactants, organic solvents ndi zina zotero. Pali mitundu yambiri ya mankhwala oyezera, ndipo mitundu ya mankhwala oyezera omwe amagwiritsidwa ntchito m'mapepala osiyanasiyana si yofanana. Mankhwala oyezera okwera kwambiri kapena butyl cellulose angagwiritsidwe ntchito m'mapepala oyezera okhala ndi solvent. Mankhwala oyezera okhala ndi madzi okhala ndi ma surfactants kapena polyacrylic acid, carboxymethyl cellulose

Chiyambi cha malonda ndi zinthu zake

Zinthu zoyezera zimagawidwa m'magulu awiri. Choyamba ndi kusintha kukhuthala kwa filimu ndi nthawi yoyezera kuti igwire ntchito, mtundu uwu wa chinthu choyezera umakhala makamaka zinthu zina zosungunulira kapena zosakaniza za organic zomwe zimakhala ndi malo otentha kwambiri, monga isoporone, diacetone alcohol, Solvesso150; China ndi kusintha mawonekedwe a pamwamba pa filimu kuti igwire ntchito, anthu ambiri adati chinthu choyezera chimatanthauza mtundu uwu wa chinthu choyezera. Mtundu uwu wa chinthu choyezera umasamukira pamwamba pa filimu chifukwa chosagwirizana pang'ono, umakhudza mawonekedwe a pamwamba pa filimu monga INTERfacial tension, ndipo umapangitsa filimuyo kukhala yoyezera bwino.

gwiritsani ntchito

Ntchito yaikulu ya utoto ndi kukongoletsa ndi kuteteza, ngati pali zolakwika pakuyenda ndi kulinganiza, sizimangokhudza mawonekedwe okha, komanso zimawononga ntchito yoteteza. Monga kupangika kwa kufupika komwe kumachitika chifukwa cha makulidwe a filimu sikokwanira, kupangika kwa mabowo ang'onoang'ono kudzapangitsa kuti filimuyo isapitirire, izi zichepetsa chitetezo cha filimuyo. Pakupanga utoto ndi kupanga filimuyo, padzakhala kusintha kwakuthupi ndi kwamankhwala, kusinthaku ndi mtundu wa utotowo, zidzakhudza kwambiri kuyenda ndi kulinganiza kwa utotowo.
Pambuyo poti chophimbacho chagwiritsidwa ntchito, ma interface atsopano adzawonekera, nthawi zambiri mawonekedwe amadzimadzi/olimba pakati pa chophimbacho ndi substrate ndi mawonekedwe amadzimadzi/gasi pakati pa chophimbacho ndi mpweya. Ngati mphamvu ya INTERFAcial YA THE madzi/olimba pakati pa chophimbacho ndi substrate ili yokwera kuposa mphamvu yayikulu ya pamwamba pa substrate, chophimbacho sichidzatha kufalikira pa substrate, zomwe mwachibadwa zimapanga zolakwika monga mabowo a fisheye ndi shrinkage.
KUVUTA KWA CHINSINSI PA NTCHITO YOUMITSA filimuyi kudzapangitsa kuti kutentha, kuchulukana, ndi kusiyana kwa mphamvu ya pamwamba pa filimuyi kukhale pakati pa pamwamba ndi mkati mwa filimuyi. Kusiyana kumeneku kumabweretsa kuyenda kosasunthika mkati mwa filimuyi, ndikupanga chomwe chimatchedwa Benard vortex. Benard vortex imabweretsa khungu la lalanje; M'makina okhala ndi utoto woposa umodzi, ngati pali kusiyana kwina pakuyenda kwa tinthu ta utoto, Benard vortex ingayambitsenso mtundu ndi tsitsi loyandama, ndipo kapangidwe koyima kadzatsogolera ku mizere ya silika.
NJIRA YOUMITSA FILIMU YA UTOTO NTHAWI ZINA IMAPANGA tinthu tina ta COLLOIDAL tosasungunuka, kupanga tinthu ta COLLOIDAL tosasungunuka kumabweretsa kupangika kwa mphamvu ya pamwamba, nthawi zambiri kumabweretsa kupanga mabowo ocheperako mu filimu ya utoto. Mwachitsanzo, MU NJIRA YOTHANDIZA YOPHUNZITSA, KUMENE NJIRAYI ILI NDI RESIN YOPOSA IMODZI, utomoni wosasungunuka kwambiri ungapange tinthu ta colloidal tosasungunuka pamene chosungunulira chimasinthasintha panthawi yowumitsa filimu ya utoto. Kuphatikiza apo, mu kapangidwe kake kamene kali ndi surfactant, ngati surfactant sigwirizana ndi dongosololi, kapena mu njira yowumitsa ndi kusinthasintha kwa chosungunulira, kusintha kwa kuchuluka kwake kumabweretsa kusintha kwa kusungunuka, kupangika kwa madontho osagwirizana, kumapanganso kupsinjika kwa pamwamba. Izi zingayambitse kupanga mabowo ocheperako.
Pakupanga utoto ndi kupanga filimu, ngati pali zinthu zoipitsa zakunja, izi zingayambitsenso kuchepa kwa dzenje, kusowa kwa maso ndi zolakwika zina. Zinthu zoipitsazi nthawi zambiri zimachokera ku mpweya, zida zomangira ndi mafuta a substrate, fumbi, utoto, nthunzi ya madzi, ndi zina zotero.
Kapangidwe ka utoto wokha, monga kukhuthala kwa kapangidwe, nthawi youma, ndi zina zotero, zidzakhudzanso kwambiri kulinganiza komaliza kwa filimu ya utoto. Kukhuthala kwakukulu kwa kapangidwe ndi nthawi yochepa youma nthawi zambiri zimapangitsa kuti pamwamba pake pakhale kulinganiza koipa.
Chifukwa chake, ndikofunikira kuwonjezera choyezera, kudzera mu choyezera panthawi yomanga ndi kupanga filimu ya kusintha kwina ndi mawonekedwe a choyezera kuti zisinthe, kuti utoto ukhale wofanana bwino.

phukusi ndi mayendedwe

B. Chogulitsachi chingagwiritsidwe ntchito, 25KG, 200KG, 1000KG MABERE.
C. Sungani yotsekedwa m'nyumba pamalo ozizira, ouma komanso opumira mpweya. Zidebe ziyenera kutsekedwa bwino mukatha kugwiritsa ntchito nthawi iliyonse musanagwiritse ntchito.
D. Chogulitsachi chiyenera kutsekedwa bwino panthawi yonyamula kuti chisasakanikirane ndi chinyezi, alkali ndi asidi wamphamvu, mvula ndi zinyalala zina.
