Zotchingira zakunja zimagwira ntchito yofunika kwambiri poteteza nyumba kuzinthu zachilengedwe, kupereka zokongola komanso kuonetsetsa kuti zizikhala zolimba.Timafufuza za ma cellulose ethers, ntchito yawo ngati zonenepa ndi zosintha za rheology, komanso momwe zowonjezera zimakhudzira zinthu monga kumamatira, kusinthasintha kwanyengo, komanso kulimba kwa zokutira.Kwa opanga ma formula ndi opanga omwe akufuna kupanga zokutira zakunja zapamwamba kwambiri, kumvetsetsa kwathunthu kwazinthu izi ndikofunikira.
dziwitsani:
Zovala zakunja ndizofunikira kwambiri poteteza nyumba ku nyengo yoyipa, ma radiation a UV, zowononga ndi zina zachilengedwe.Ma cellulose ether omwe amachokera ku magwero a cellulose achilengedwe komanso zowonjezera zambiri zimathandizira kwambiri kukulitsa zokutira izi.
Ma cellulose ethers mu zokutira kunja kwa khoma:
2.1.Chidule cha ma cellulose ethers:
Ma cellulose ethers akuphatikizapo methylcellulose (MC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), carboxymethylcellulose (CMC), ndi zina zotero, zomwe zimagwiritsidwa ntchito kwambiri panja chifukwa cha katundu wawo wapadera.Mu utoto penti.Ma polima awa amakhala ngati zokhuthala, zomangira, ndi zosintha za rheology, zomwe zimapatsa zokutira zomwe zili zofunika.
2.2.Makulidwe katundu:
Ma cellulose ethers ndi zokhuthala bwino zomwe zimawonjezera kukhuthala kwa zokutira, kulimbikitsa kugwiritsa ntchito bwino komanso kuchepetsa kugwa.Mapangidwe a maselo a cellulose ethers amasunga madzi, kuwonetsetsa kukhuthala koyenera komanso kusasinthika kwa ntchito.
2.3.Kusintha kwa Rheological:
Kuwongolera machitidwe a rheological a zokutira zakunja ndikofunikira kuti mukwaniritse zomwe mukufuna kugwiritsa ntchito.Ma cellulose ethers amagwira ntchito yofunika kwambiri pakusintha kamvekedwe ka zokutira, kuwongolera kuyenda kwawo komanso kusanja.Izi zimapangitsa kuti ntchito ikhale yosavuta komanso imapangitsa kuti makulidwe a yunifolomu apangidwe.
Zowonjezera zowonjezera utoto wakunja:
3.1.Wothandizira Adhesion:
Adhesion ndi chinthu chofunikira kwambiri chomwe chimakhudza magwiridwe antchito akunja kwa khoma.Zowonjezera zosiyanasiyana, monga ma silanes ndi ma polima a acrylic, zimakulitsa kumamatira polimbikitsa mgwirizano wolimba pakati pa zokutira ndi gawo lapansi.Izi zimatsimikizira kulimba kwa nthawi yayitali komanso kukana kupukuta kapena matuza.
3.2.Weathering zowonjezera:
Utoto wakunja umakhudzidwa ndi nyengo zosiyanasiyana, monga kuwala kwa dzuwa, mvula, ndi kusinthasintha kwa kutentha.Zolimbitsa thupi za UV, zolepheretsa kuwala kwa amine (HALS), ndi zina zowonjezera nyengo zimateteza zokutira kuti zisawonongeke chifukwa cha ma radiation a UV ndi ma oxidation, potero amakulitsa moyo wawo wautumiki.
3.3.Antifungal ndi antimicrobial agents:
Kunja kumatengera kukula kwachilengedwe, kuphatikiza nkhungu ndi algae.Kuphatikiza kwa antifungal ndi antibacterial agents (monga biocides) kumalepheretsa kukula kwa tizilombo toyambitsa matenda ndikusunga mawonekedwe ndi kulimba kwa zokutira.
3.4.Woletsa madzi:
Zida zoteteza madzi ndizofunikira kuti utoto wakunja uteteze kulowa kwa madzi, zomwe zingayambitse kuwonongeka kwa ntchito ndi kutayika.Silicones, silanes ndi fluorinated compounds amagwiritsidwa ntchito kawirikawiri zothamangitsa madzi zomwe zimapanga chotchinga cha hydrophobic ndikuwonjezera kukana kwa zokutira ku kuwonongeka kwa madzi.
3.5.Impact resistance enhancer:
Kunja kungathe kuwonongeka kuchokera kuzinthu zosiyanasiyana, kuphatikizapo matalala kapena kukhudzana.Kuphatikizika kwa zowonjezera zolimbana ndi mphamvu, monga ma polima a elastomeric kapena ma microspheres, kumatha kupititsa patsogolo luso la zokutira kuti lipirire kupsinjika kwamakina ndikusunga zoteteza.
Kugwirizana pakati pa cellulose ethers ndi zowonjezera:
Kuphatikiza kwa ma cellulose ethers ndi zowonjezera mu utoto wakunja nthawi zambiri kumapangitsa kuti pakhale mgwirizano womwe umapangitsa magwiridwe antchito onse.Chikhalidwe cha thixotropic cha cellulose ethers chimakwaniritsa dispersing ndi stabilizing katundu wa zina zina, kusintha ntchito ndi filimu mapangidwe.
Maphunziro ndi zitsanzo:
Gawoli limapereka zitsanzo zenizeni za kupangidwa bwino kwa utoto wakunja kuphatikiza ma cellulose ether ndi zowonjezera zosiyanasiyana.Kafukufuku akuwonetsa zovuta zomwe zayankhidwa, kuwongolera komwe kwachitika, komanso kupambana konse kwa kapangidwe kazinthu zosiyanasiyana zachilengedwe.
Zam'tsogolo ndi zatsopano:
Pomwe kufunikira kwa zokutira zakunja zogwira ntchito kwambiri kukupitilira kukula, makampani akuchitira umboni kupitiliza kufufuza ndi chitukuko.Zomwe zikuchitika m'tsogolomu zingaphatikizepo kuphatikiza zokutira zanzeru, ma nanomatadium apamwamba ndi zowonjezera zokhazikika kuti zipititse patsogolo kulimba, kusamala zachilengedwe komanso kugwiritsa ntchito mphamvu.
Pomaliza:
Ma cellulose ethers ndi zowonjezera zimagwira ntchito yofunika kwambiri pakuwongolera magwiridwe antchito akunja.Kumvetsetsa bwino za katundu wawo ndi kuyanjana kwawo ndikofunikira kwa opanga ndi opanga omwe akufuna kupanga zokutira zomwe zimakhala zolimba, zomatira, zanyengo komanso mtundu wonse.Kupitilizidwa kwa zida ndi matekinoloje m'derali kumapereka chiyembekezo chakupita patsogolo kwa zokutira zakunja zamakampani omanga.
