A. polymerization:
Njirayi imayamba ndi emulsion polymerization ya monomers monga vinilu acetate ndi ethylene pamaso pa intiators ndi surfactants.Gawo ili limapanga kubalalitsidwa kwamadzi kwa tinthu ta polima.
b.Kuyanika utsi:
Kubalalitsa kwamadzi kumawumitsidwa, kusinthidwa kukhala madontho ndikuwumitsa mwachangu pogwiritsa ntchito mpweya wotentha.Chifukwa cha ufa chimakhala ndi ting'onoting'ono polima particles yokutidwa ndi colloid zoteteza.
C. Pambuyo pokonza:
Pambuyo pokonza njira ndiye kuti zitha kuchitidwa kuti muwonjezere mphamvu za ufa.Izi zingaphatikizepo kuyanika kwina, kusinthidwa pamwamba kapena kuwonjezera zowonjezera.
3. Zolemba:
Redispersible latex powder nthawi zambiri imakhala ndi izi:
Zomatira za polima: Chofunikira chachikulu nthawi zambiri chimakhala copolymer ya vinyl acetate ndi ethylene, yomwe imapereka mawonekedwe opanga mafilimu ndi kumamatira.
Zoteteza ma colloids: Zinthu izi zimalepheretsa kuphatikizika kwa tinthu ta polima panthawi yosungira ndikuonetsetsa kuti zikuyenda bwino.
Plasticizers: Kupititsa patsogolo kusinthasintha ndi kusinthika kwa chinthu chomaliza.
Dispersants: Thandizani ufa kumwazikana m'madzi ndikuthandizira kuphatikiza kwawo kukhala ma formula.
4. Kachitidwe ndi kachitidwe:
Redispersible latex ufa umapereka zinthu zingapo zofunika kuzimanga, kuphatikiza:
Kumamatira: Kumawonjezera mphamvu zomangira, makamaka kumatope ndi zomatira matailosi.
Kusinthasintha: Kumalimbitsa kukana kusweka ndi mapindikidwe, omwe ndi ofunikira kuti azitha kutchingira madzi nembanemba ndi caulk.
Kukanika kwa Madzi: Kumateteza ku chinyezi komanso kumapangitsa kulimba m'malo onyowa.
Processability: Kupititsa patsogolo kagwiridwe ndi kagwiritsidwe ntchito kakuphatikiza kowuma.
5. Kugwiritsa ntchito:
Redispersible latex ufa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana:
a.Pilira:
Ma Tile Adhesives ndi Grouts: Sinthani kumamatira ndi kusinthasintha pakuyika matayala.
Exterior Insulation and Finishing Systems (EIFS): Limbikitsani magwiridwe antchito a EIFS popereka kusinthasintha ndi kukana ming'alu.
Mitondo ndi pulasitala: Kupititsa patsogolo mphamvu zomangirira, kugwirira ntchito bwino komanso kusagwira madzi kwa matope a simenti ndi pulasitala.
Self-Leveling Compound: Imakulitsa kuyenda ndi kumamatira kwa zinthu zodzipangira zokha pansi.
b.Paints ndi Zopaka:
Amagwiritsidwa ntchito ngati filimu yakale komanso yomangirira mu utoto wokhala ndi madzi ndi zokutira kuti azitha kumamatira komanso kulimba.
C. Zomatira:
Imawongolera kumamatira ndi kulumikizana mumitundu yosiyanasiyana ya zomatira, kuphatikiza zomatira zamatabwa ndi zomatira zomangira.
6. Ubwino:
Kugwiritsa ntchito redispersible latex ufa kuli ndi izi:
Kupititsa patsogolo katundu: Kumawonjezera zofunikira za zipangizo zomangira monga zomatira, kusinthasintha ndi kukana madzi.
Zosiyanasiyana: Zoyenera kugwiritsidwa ntchito mosiyanasiyana kuyambira pamatope ndi zomatira mpaka utoto ndi zokutira.
Zosavuta kugwira: Monga ufa wowuma, ndizosavuta kunyamula, kusunga ndikugwira, ingowonjezerani madzi kuti mubalalitsenso.
Kusamalira chilengedwe: Mafomu opangidwa ndi madzi ndi okonda zachilengedwe kuposa njira zina zosungunulira.
Kugwiritsa Ntchito Ndalama: Imathandiza kukhathamiritsa kwa mapangidwe, kuchepetsa mtengo wazinthu, komanso kuwongolera magwiridwe antchito azinthu.
7. Tsogolo la Tsogolo:
The redispersible latex powder msika ikuyembekezeka kuchitira umboni kukula kosasunthika, motsogozedwa ndi chitukuko chokhazikika cha zomangamanga, kukula kwamatauni, komanso kukwera kwa kufunikira kwa zida zomangira zogwira ntchito kwambiri.Kupita patsogolo kwaukadaulo komwe kumafuna kupititsa patsogolo magwiridwe antchito azinthu komanso kukulitsa madera ogwiritsira ntchito kuyenera kupititsa patsogolo kukula kwa msika.Kuphatikiza apo, kuzindikira kokulirapo kwa njira zomangira zokhazikika kumatha kuyambitsa kukhazikitsidwa kwa njira zina zoteteza zachilengedwe, monga ma ufa a latex opangidwanso.
Redispersible latex ufa umagwira ntchito yofunika kwambiri pakuwongolera magwiridwe antchito a zida zomangira m'mafakitale osiyanasiyana.Makhalidwe ake apadera komanso kusinthika kwake kumapangitsa kuti ikhale yofunikira pakugwiritsa ntchito kuyambira zomatira matailosi ndi matope mpaka utoto ndi zokutira.Ndi kupitilira kwatsopano komanso kugogomezera kwambiri pakumanga kokhazikika, kufunikira kwa ufa wa latex wopangidwanso kukuyembekezeka kupitiliza kukula, ndikuyendetsa kafukufuku ndi chitukuko mderali.
