Ekunze machira anoita basa rakakosha mukudzivirira zvivakwa kubva kune zvakatipoteredza, zvichipa aesthetic kukwezva uye kuve nechokwadi chekugara kwenguva refu.Isu tinoongorora zvimiro zve cellulose ethers, basa rawo semakobvu uye rheology modhifita, uye mabatiro ezvekuwedzera pazvivakwa zvakaita sekunamira, mamiriro ekunze, uye kusimba kwekupfeka kwese.Kune vanogadzira uye vagadziri vanovavarira kuvandudza emhando yepamusoro yekupfeka ekunze, kunzwisisa kuzere kweizvi zvinongedzo kwakakosha.
suma:
Kuvhara kwekunze kwakakosha mukudzivirira zvivakwa kubva kune yakaoma mamiriro ekunze, UV mwaranzi, zvinosvibisa uye zvimwe zvakatipoteredza.Cellulose ethers inotorwa kubva kune yakasikwa cellulose masosi uye huwandu hwekuwedzera hunobatsira zvakanyanya mukusimudzirwa kweaya machira.
Cellulose ethers mune ekunze madziro machira:
2.1.Mhedziso ye cellulose ethers:
Cellulose ethers inosanganisira methylcellulose (MC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), carboxymethylcellulose (CMC), nezvimwewo, iyo inoshandiswa zvakanyanya mumashandisirwo ekunze nekuda kwekusiyana kwawo.Mumadziro pendi.Aya mapolymers anoita seanokora, mabhainda, uye rheology modhifita, achipa mapeji maitiro avo akakosha.
2.2.Kukora zvinhu:
Cellulose ethers anobudirira thickeners anowedzera viscosity yekuputira, inosimudzira zvirinani kushandiswa uye kuderedza sagging.Iyo molecular chimiro che cellulose ethers inochengetedza mvura, inova nechokwadi chepamusoro viscosity uye kushandiswa kunoenderana.
2.3.Rheological shanduko:
Kudzora maitiro e rheological ekunze kwekupfeka kwakakosha kuti uwane iyo inodiwa application zvivakwa.Cellulose ethers inoita basa rakakosha mukushandura rheology yejasi, kuvandudza kuyerera kwavo uye kuyera zvivakwa.Izvi zvinowedzera kusununguka kwekushandisa uye zvinoguma mukukobvu kwekupfeka kweyunifomu.
Zviwedzerwa zvekuvandudza pendi yekunze:
3.1.Adhesion promoter:
Adhesion chinhu chakakosha chinokanganisa kushanda kwekunze kwemadziro machira.Akasiyana-siyana ekuwedzera, senge silanes uye acrylic polymers, anonamira kunamatira nekusimudzira chisungo chakasimba pakati pejasi uye substrate.Izvi zvinogonesa kusimba kwenguva refu uye kuramba kubheuka kana kuputika.
3.2.Weathering additives:
Pendi yekunze inoratidzwa kune akasiyana mamiriro ekunze, anosanganisira chiedza chezuva, mvura, uye kushanduka kwekushisa.UV stabilizer, inodzivirira amine light stabilizers (HALS), uye zvimwe zvinowedzera mamiriro ekunze zvinodzivirira machira kubva mukuora kunokonzerwa neiyo UV radiation uye oxidation maitiro, nekudaro vachiwedzera hupenyu hwavo hwesevhisi.
3.3.Antifungal uye antimicrobial agents:
Kunze kwekunze kunokanganisa kukura kwebiological, kusanganisira mold uye algae.Kuwedzerwa kweantifungal uye antibacterial agents (zvakadai sebiocides) kunodzivirira kukura kwe microorganisms uye kuchengetedza kutaridzika uye kusimba kwekuputira.
3.4.Waterproofing agent:
Mapurisa ekudzivirira mvura akakosha kune pendi yekunze kudzivirira kupinda kwemvura, izvo zvinogona kutungamirira mukuderera kwekuita uye kurasikirwa.Silicones, silanes uye fluorinated makomisheni anowanzo shandiswa zvinodzoreredza mvura izvo zvinogadzira hydrophobic chipingamupinyi uye chinowedzera kupotera kwekudzivirira kukuvadzwa kwemvura.
3.5.Impact resistance enhancer:
Nzvimbo dzekunze dzinokwanisa kukuvara kubva kwakasiyana siyana, kusanganisira chimvuramabwe kana kubata kumeso.Kuwedzerwa kwemaitiro-resistant ekuwedzera, senge elastomeric polymers kana microspheres, inogona kuvandudza kugona kwejasi kutsungirira kushushikana kwemagetsi uye kuchengetedza zvidziviriro zvayo.
Synergy pakati pe cellulose ethers uye additives:
Iko kusanganiswa kwe cellulose ethers uye zvinowedzera mune zvekunze pendi zvinowanzogadzira synergistic mhedzisiro inovandudza kuita kwese.Iyo thixotropic chimiro che cellulose ethers inozadzisa kuparadzira uye kudzikamisa zvimiro zvezvimwe zvinowedzera, kuvandudza mashandisirwo uye firimu kuumbwa.
Zvidzidzo uye mienzaniso:
Ichi chikamu chinopa mienzaniso yepasirese yeakabudirira ekunze pendi maumbirwo achibatanidza cellulose ether uye akasiyana ekuwedzera.Zvidzidzo zvenyaya zvinosimbisa matambudziko akatariswa, kuvandudzwa kwaitwa, uye kubudirira kwese kwekugadzira pasi pemamiriro ekunze akasiyana.
Ramangwana mafambiro uye zvitsva:
Sezvo kudiwa kwepamusoro-kushanda kwekunze kwekupfeka kuri kuramba kuchikura, indasitiri iri kupupurira kuenderera mberi kwekutsvaga nekusimudzira.Mafambiro emangwana anogona kusanganisira kubatanidzwa kweakangwara coatings, advanced nanomaterials uye inogoneka yekuwedzera kuti uwedzere kuvandudza kusimba, hushamwari hwezvakatipoteredza uye kushanda nesimba.
mukupedzisa:
Cellulose ethers uye additives inoita basa rakakosha mukuvandudza kushanda kwekunze kwekunze.Kunyatsonzwisisa kwezvivakwa zvavo uye kudyidzana kwakakosha kune vanogadzira uye vagadziri vari kutsvaga kugadzira machira ane kusimba kwakasimba, adhesion, mamiriro ekunze uye mhando yese.Kuenderera mberi kwekuvandudzwa kwezvinhu uye matekinoroji munzvimbo ino kunopa tariro yekuenderera mberi kufambira mberi mumachira ekunze eindasitiri yekuvaka.
