Wobwezeretsedwa Polider Polyder (RDP)Ndi chinthu cha ufa chopangidwa ndi kuyanika polymer emulsion, yomwe imagwiritsidwa ntchito muzinthu monga zomanga, zomata, zomatira, ndi matae a tiles. Ntchito yake yayikulu ndikugulitsanso madzi, kupereka chotsatsa bwino, kututa madzi, kukana madzi, kutsutsana ndi nyengo.
Kuphatikizidwa kwa polimature polipper (RDP) kumatha kusanthulidwa kuchokera ku magawo angapo, makamaka kuphatikiza zigawo zotsatirazi:
1. Polymer Resin
Gawo la Core of Pollmer Polder ndi polymer resin, omwe nthawi zambiri amakhala polymer omwe amapezeka ndi emulsion polymerization. Maunitsi wamba polymer amaphatikizapo:
Mowa (PVE): ali ndi zotsatsa bwino komanso katundu wopanga mafilimu ndipo amagwiritsidwa ntchito kwambiri pomanga zida.
Ma polyacrylates (monga polyacrylate, polyirethas, ndi zina zambiri:
Polystyrene (PS) kapena ethylene-vinyl acetate Coptolmer (Eva): Nthawi zambiri amagwiritsidwa ntchito kukonza zinthu zopanga zamafadi, zimawonjezera madzi kukana, komanso kukana madzi.
Polymethyl Methacrylate (PMMA): PANODZI ili ndi ukalamba wabwino komanso ukalamba.
Makina owopa awa amalumikiza kudzera pakusintha kwa ma polymerization, kenako madzi mu emulsion amachotsedwa ndi kuyanika, kenako ndikuwuma ufa wa polder (RDP) mu mawonekedwe a ufa.
2. Zogwiritsa ntchito
Pofuna kukhalabe okhazikika pakati pa tinthu tating'onoting'ono ndikupewa kuphatikizika mu ufa, kuchuluka kwa okonda okonda kuwonjezeredwa pakupanga. Udindo wa okonda ndikuchepetsa umunthu pakati pa tinthu ndikuthandizira tinthu tating'onoting'ono. Zofananira ndizophatikizira:
Osakhala ogwiritsa ntchito (monga ma polytetes, polyethylene glycols, etc.).
Anionic surfactonts (monga mafuta a acid acid, alkyl sulfonites, etc.).
Izi zowonjezera zimatha kukulitsa kuperekera kwa polimatuko polima (RDP) s, kulola ufa waposachedwa kuti apange emulsion mutatha kuwonjezera madzi.
3.. Mafayilo ndi otsatsa
Pofuna kusintha magwiridwe antchito a matex a matex ndikuchepetsa mtengo, mafilimu ena ena amathanso kuwonjezeredwa pakupanga. Pali mitundu yambiri ya mafakitale, ndipo zofala zimaphatikizapo:
Calcium Carbonate: omwe amagwiritsidwa ntchito kawirikawiri omwe amagwiritsidwa ntchito kwambiri omwe angakulitse zomatira ndikusintha mphamvu.
Talc: imatha kuwonjezera madzi komanso kukana zinthuzo.
Mineral mchere: monga Bentonite, wokutira graphite, etc., amatha kukulitsa kukana ndi kukana kwa madzi.
Otsatsa amagwiritsidwa ntchito nthawi zambiri amasintha mafayilo a malonda kuti asinthire pazomanga zosiyanasiyana. Otsatsa ofala amaphatikizapo hydroxypropyl methylcellulose (hpmc) ndi mowa wa polyvinyl.
4.. Anti-Cating Edge
Pazinthu za ufa, pofuna kupewa kugwera panthawi yosungira ndi mayendedwe, othandizira otsutsa amathanso kuwonjezeredwa pakupanga. Anti-Caking Agets makamaka ndi zinthu zina zabwino kwambiri, monga aluminium silika, silc. Zinthu izi zitha kupanga filimu yoteteza tinthu toyambitsa tinthu toyambitsa matenda.
5. Zowonjezera zina
Wobwezeretsedwa Polider ufa (RDP) ikhozanso kukhala ndi zowonjezera zapadera kuti zithandizire mtundu wina:
Wothandizira Wogwiritsa Ntchito UV: Kuwongolera nyengo yolimbana ndi kutsutsa kwa nkhaniyo.
Antibacterial wothandizila: zimachepetsa kukula kwa tizilombo tating'onoting'ono, makamaka mukamagwiritsidwa ntchito m'malo otentha.
Phukusi: Kuwongolera kusinthasintha komanso kukana kukana kwa matex ufa.
Akanirfapt: Kuletsa zinthu kuti zisaukidwe m'malo otsika kutentha, kumakhudza ntchito ndi kugwiritsa ntchito zotsatira zake.
6. Chinyontho
Ngakhale atabwezedwa polima ufa (RDP) ili mu ufa wowuma, zimafunikiranso kuchuluka kwa chinyezi pa nthawi yopanga, ndipo chinyontho chimakhala cholamuliridwa pansipa 1%. Zokhala ndi chinyezi choyenera zimathandizira kukhalabe ndi madzi ambiri komanso kukhazikika kwakanthawi kwa ufa.
Udindo ndi magwiridwe antchito obwezeretsedwa polima (RDP)
UTHENGA WABWINO KWA Ufa wobwezeretsedwa (RDP) ndikuti ikhoza kubwezeretsedwanso kuti ipange emulsion mutawonjezera madzi, ndipo ali ndi machitidwe ofunikira:
Zotsatira zabwino: kupangitsa kuti luso la zopindulitsa ndi zomatira, ndikuwongolera kulimba mtima pakati pa zida zomangira.
Kuthana ndi kusinthasintha: kusintha kuchuluka kwa zokutira, kukulitsa kutsutsana kwake ndi kukana.
Kuthetsa Madzi: Kulimbana ndi madzi kukanazo, zoyenera kugwiritsa ntchito panja kapena malo achinyontho.
Kukana Kwambiri: Sinthani zakutha kwa UV, anti-ukalamba ndi zina, ndikuwonjezera moyo wake.
Kukana Kukana: Ili ndi kukana kwabwino ndipo ndioyenera kutsutsana ndi zofunikira zotsutsana nawo pantchito zomanga.
BDPimapangidwa ndi kusintha emulsion polmer kukhala ufa kudzera munjira yodabwitsa. Ili ndi zinthu zambiri zabwino ndipo zimagwiritsidwa ntchito kwambiri pomanga, zomatira, zomatira ndi minda ina. Kusankhidwa ndi kuchuluka kwa zosakaniza zake kumakhudza mwachindunji.
