Kodi mungatani kuti mukonzekere ufa wokwezedwa?

Kubwezeretsedwanso polima (RDP) ndi nkhani yofunika kwambiri yogwiritsidwa ntchito kwambiri pomanga, zomatira, zomatira ndi minda ina. Amapangidwa ndi utsi wowuma ndikupukusa bwino komanso kutsatsa.

1. Kukonzekera kwa zinthu
Zida zazikulu zopanga zotsekera posachedwa zimaphatikizapo:
Polimer emulsion: monga mowa wa polyvinyl (pva), ethylene-vanyl acetate (Eva), styrene-macrytet (st), etc.
Colloid Colloid: monga mowa wa polyvinyl, methyl cellulose, hydroxypropyl methyl celyl celyl cellouse, etc., imagwiritsidwa ntchito popewa tinthu tating'onoting'ono.
Defomer: Ankakonda kuchotsa chithovu popanga, monga mafuta a silika ndi Polyther decoamer.
Wokhazikika: monga sodium dodecylbene sulfonate (sdb), sodium polyacrylate, etc., omwe amagwiritsidwa ntchito kukhazikika.

2. Kukonzekera kwa Emulsion
Sankhani molomers yoyenera malinga ndi formula yomwe ikuwonetsa polymerization ikukonzekeretsa emulsion ndi malo ofunikira. Pakukonzekera emulsion, njira yotsatirayi idziwike:
Kusankhidwa kwa Monomeer ndi Vomeromer: Sankhani monomer oyenera, monga Ethylene, Vinyl Acetate Womaliza, ndi zina mwazomwezo kuti zitsimikizire kuti emulsion.
Emulsion Polymerization: Nthawi zambiri zaulere zaulere zimagwiritsidwa ntchito pollmerzer kukhala polimer emulsion. Kuchita kwa polymerization kumayenera kuchitika mokhazikika pamachitidwe olamulidwa mosamalitsa, kuphatikiza kutentha, liwiro losangalatsa, oyambitsa oyambitsa, etc.
Kuphatikiza kwa Colloid Colloid ndi Stateger: Onjezani kuchuluka koyenera ndi colloid yoteteza ndi emulsion kuti ilepheretse emulsion panjira yonyansa.

3.. Kudzitukumula kwa emulsion
Asanayikepo zopota, emulsion imayenera kukongoletsa, makamaka kuphatikiza njira zotsatirazi:
Kusefera: Chotsani zonyansa pa emulsion kudzera mu fyuluta kapena pentiyifuge kuti muwonetsetse kuti emuliri.
Kukhazikika kwa Emulsion ku zomwe zili m'malo olimba kudzera mu EvaPot kapena Field Filution kuti musinthe kuyanika.

4. Kuwuma
Kuwuma kopukutira ndi njira yolumikizira yobwezeretsera ufa. Malingaliro ake ali motere:
Kusankhidwa kwa nsanja youma Zipangizo zomwe zimagwiritsidwa ntchito zimakonda kuphatikizira tinthu tating'onoting'ono tomwe timathira nsanja komanso zopopera utsi.
Kukhazikitsa kwa magawo owuma: Khazikitsani kutentha koyenera kwa mpweya, kutentha kwa mpweya ndi ma swray. Nthawi zambiri, kutentha kwa mpweya kumawongoleredwa mu 150-200 ℃, ndipo kutentha kwa mpweya kumayendetsedwa pa 60-80 ℃.
Kuwuma: Kusintha kwa emulsion kumavomerezedwa kukhala madontho abwino kudzera mu sprayer, ndikulumikizana mwachangu ndi mpweya wotentha munsanja yowuma, ndipo madziwo amasinthidwa kuti apange tinthu tating'onoting'ono.
Kutolere pa ufa: ufa wouma wated Ufa wophatikizidwa wa latax umafunika kukhazikika ndipo tinthu tating'onoting'ono timachotsedwa ndi kuwunika kuti zitsimikizire kufanana kwa malonda.

5. Kusaka positi ndi kunyamula
Ufa wowuma wa latx wowuma umafunika kutumizidwa moyenera kuti awonetsetse kuti ali ndi magwiridwe ake okhazikika. Kukonzekera pambuyo pake kumaphatikizapo:
Chithandizo cha anti-Cating: Onjezani othandizira otsutsa (monga talcum ufa (anicon dioxide) mpaka pansi pa ufa kuchokera ku ufa kuchokera pakusungidwa ndi mayendedwe.
Kuyika: Malinga ndi zosowa za kasitomala, ufa wa latex umatsekeka mu chinyezi komanso zikwama kapena migolo yotsimikizika. Chinyezi chimayenera kulamulidwa mosamalitsa pakuyendetsa njira kuti mupewe ufa kuti usatenge chinyezi.

6. Control Control
Panthawi ya kupanga, kuwongolera koyenera kumafunikira kuti zitsimikizire kuti zisonyezo za magwiridwe antchito aposachedwa. Zinthu zodziwika bwino ndizophatikiza:
Kugawa kwa tinthu: tinthu tating'onoting'ono tofala kwa ufa kumadziwika ndi gawo la laser tinthur kuti muwonetsetse kuti pali kufanana kwa chinthucho.
Mphamvu yotsatsa: Yesani mphamvu yotsatsa ya cethex ufa wa magawo osiyanasiyana kuti atsimikizire mayendedwe ake.
Kukonzanso: Sakanizani ufa wa latx ndi madzi kuti muwone ngati ungabadwenso ndikubwezeretsedwanso ku dziko la emulsion.

7. Kugwiritsa Ntchito ndi Kusamala
Ufa wokwezeka wa latx umagwiritsidwa ntchito kwambiri pakumanga matope, matoma a matayala, khoma la khoma la zisudzo ndi minda ina. Malangizo otsatirawa akufunika kudziwa mukamagwiritsa ntchito:

Zosachedwa: ufa wa latedx uyenera kusungidwa m'malo owuma komanso ozizira kuti musamatenthe bwino komanso chinyezi.
Kugwiritsa ntchito: malinga ndi zofunika mwatsatanetsatane, onjezani utoto wa latx moyenera kuti mupeze magwiridwe antchito abwino.
Ndi zina zowonjezera: Kubwezeredwanso ufa nthawi zambiri kumagwiritsidwa ntchito ndi zowonjezera zina (monga ma cellulose ether, decomer) kuti apititse patsogolo momwe zinthu ziliri.

Kubwezeretsedwanso ndi ufa wosakhala ndi luso labwino kumatha kupangidwa bwino. Mukupanga, ndikofunikira kusintha malinga ndi momwe zinthu zopangira ndi zofunikira zopangira zotsimikizirika zokhazikika komanso zodalirika zomaliza.
