Latex ufa-Sinthani kusasinthasintha ndi kuterera kwa dongosolo mumkhalidwe wosakanikirana wonyowa. Chifukwa cha makhalidwe a polima, kugwirizana kwa zinthu zosakaniza zonyowa kumapangidwira bwino, zomwe zimathandiza kwambiri kuti zitheke; mutatha kuyanika, imapereka kumamatira kumtunda wosalala komanso wandiweyani. Relay, sinthani mawonekedwe a mchenga, miyala, ndi pores. Pansi pa malo owonetsetsa kuchuluka kwa kuonjezera, akhoza kupindula mu filimu pa mawonekedwe, kotero kuti zomatira za matayala zimakhala ndi kusinthasintha kwina, zimachepetsa modulus zotanuka, ndipo zimatengera kupsinjika kwa kutentha kwa kutentha kwakukulu. Pankhani ya kumizidwa m'madzi pambuyo pake, padzakhala zopsinjika monga kukana madzi, kutentha kwa bafa, ndi kusinthika kwa zinthu zosagwirizana (matayilo opindika kokwanira 6 × 10-6/℃, konkire ya simenti yopindika 10 × 10-6 / ℃), ndikuwongolera kukana kwanyengo. Hydroxypropyl Methyl Cellulose HPMC-Kupereka madzi osungika bwino komanso kugwira ntchito kwamatope atsopano, makamaka pamalo onyowa. Pofuna kuonetsetsa kuti ma hydration akuyenda bwino, amatha kuteteza gawo lapansi kuti lisamalowe m'madzi ambiri komanso kuti asasunthike. Chifukwa cha malo ake opangira mpweya (1900g/L—-1400g/LPO400 mchenga 600HPMC2), kachulukidwe ka zomatira matailosi kumachepetsedwa, kupulumutsa zida ndikuchepetsa zotanuka zamatope olimba.
Tile adhesive redispersible latex ufa ndi wobiriwira, wokonda zachilengedwe, womangamanga wopulumutsa mphamvu, wapamwamba kwambiri wopangira ufa wopangira zinthu zambiri, ndipo ndizofunikira komanso zofunikira zowonjezera zowonjezera pamatope osakaniza owuma. Ikhoza kupititsa patsogolo ntchito ya matope, kuonjezera mphamvu ya matope, kuonjezera mphamvu zomangirira pakati pa matope ndi magawo osiyanasiyana, kupititsa patsogolo kusinthasintha ndi kugwira ntchito, mphamvu zopondereza, mphamvu zosinthika, kukana kuvala, kulimba, ndi kukhuthala kwamatope. Relay ndi mphamvu posungira madzi, constructability. Magwiridwe a matailosi omatira opangidwanso ndi latex ufa ndi amphamvu, ndipo zomatira zomatira za latex ufa zimakhala ndi kuthekera kwakukulu kolumikizana komanso mawonekedwe apadera. Choncho, ntchito yawo ndi yotakata kwambiri. Udindo wa hydroxypropyl methylcellulose amatenga gawo la kusunga madzi, thickening ndi ntchito yomanga kumayambiriro siteji, ndi redispersible latex ufa wa zomatira matailosi amasewera mbali ya mphamvu mu siteji yotsatira, amene amatenga mbali zabwino kwambiri mu kulimba, asidi ndi alkali kukana ntchito. Zotsatira za matailosi zomatira redispersible ufa ufa pamatope atsopano: kutalikitsa nthawi yogwira ntchito ndikusintha nthawi kuti apititse patsogolo ntchito yosungira madzi, kuti atsimikizire kuti simenti imatenthedwa bwino ndikuwongolera kukana kwa sag (wapadera kusinthidwa mphira ufa) ndikuwongolera magwiridwe antchito (osavuta kugwiritsa ntchito gawo lapansi ndi zomangamanga zapamwamba, zosavuta kukanikiza matailosi mu zomatira zomatira, zomatira, kuphatikiza zomatira zabwino, zomatira, kuphatikiza zomatira zabwino) pulasitala, matabwa, matailosi akale, PVC ngakhale nyengo zosiyanasiyana nyengo , ali wabwino mapindikidwe luso.
Kuphatikizika kwa ufa wa latex wopangidwanso kwa zomatira za matailosi kumakhala ndi zotsatira zoonekeratu pakuwongolera magwiridwe antchito a zomatira za simenti, ndipo zimakhudza kwambiri mphamvu yomangirira, kukana madzi, komanso kukana kukalamba kwa zomatira. Pakali pano, pali mitundu yambiri ya redispersible latex ufa kwa zomatira matailosi pa msika, monga akiliriki redispersible latex ufa, styrene-acrylic ufa, vinilu acetate-ethylene copolymers, etc. Nthawi zambiri, zomatira matailosi ntchito matailosi zomatira pa msika Ambiri redispersible latex acepolymers.
(1) Pamene kuchuluka kwa simenti kumawonjezeka, mphamvu yapachiyambi ya ufa wa latex wopangidwanso wowonjezera matailosi imawonjezeka, ndipo nthawi yomweyo, mphamvu zomatira zomata pambuyo pa kumizidwa m'madzi ndi mphamvu zomatira pambuyo pa ukalamba wa kutentha zimawonjezeka.
(2) Ndi kuwonjezeka kwa kuchuluka kwa ufa wa latex wopangidwanso wopangira zomatira matailosi, mphamvu yomangika ya latex yopangidwanso ndi zomatira zomatira m'madzi pambuyo pa kumizidwa m'madzi ndi mphamvu yomangirira pambuyo pa ukalamba wotentha idakula molingana, koma kukalamba kwamafuta Pambuyo pake, mphamvu yomangira yolimba idakula kwambiri.
Chifukwa cha zokongoletsa zake zabwino komanso zogwira ntchito monga kukhazikika, kukana madzi ndi kuyeretsa kosavuta, matayala a ceramic amagwiritsidwa ntchito kwambiri: kuphatikizapo makoma, pansi, denga ndi maiwe osambira, etc., ndipo angagwiritsidwe ntchito m'nyumba ndi kunja. Njira yophatikizira matailosi ndi njira yomangira yokhuthala, ndiye kuti, choyamba ikani matope wamba kumbuyo kwa matailosi, kenako ndikusindikiza matailosi kumunsi. Makulidwe a matope wosanjikiza ndi pafupifupi 10 mpaka 30mm. Ngakhale kuti njirayi ndi yabwino kwambiri pomanga pazitsulo zosagwirizana, kuipa kwake ndi kutsika kwa matayala a matailosi, zofunika kwambiri za luso la ogwira ntchito, kuwonjezeka kwa chiwopsezo cha kugwa chifukwa cha kusasinthasintha kwamatope, komanso kuvutika kukonza matope pamalo omanga. Ubwino umayendetsedwa mosamalitsa. Njirayi ndi yoyenera kwa matailosi okhala ndi kuchuluka kwa mayamwidwe amadzi. Musanaphatikize matailosi, matailosi ayenera kuviikidwa m'madzi kuti apeze mphamvu zokwanira zomangira.
Pakalipano, njira yopangira matayala yomwe imagwiritsidwa ntchito kwambiri ku Ulaya ndi njira yotchedwa woonda-wosanjikiza njira yomamatira, ndiko kuti, gulu la zomatira lopangidwa ndi polima lopangidwa ndi polima limaphwanyidwa pamwamba pazitsulo zoyambira kuti zimangidwe pasadakhale ndi spatula yokhala ndi mano kuti apange mikwingwirima yokwezeka. Ndipo matope wosanjikiza wa makulidwe a yunifolomu, ndiye akanikizire matailosi pamenepo ndikupotoza pang'ono, makulidwe a matope wosanjikiza amakhala pafupifupi 2 mpaka 4mm. Chifukwa cha kusinthidwa kwa cellulose ether ndi redispersible latex ufa, kugwiritsa ntchito zomatira za matailosizi zimakhala ndi ntchito yabwino yolumikizira mitundu yosiyanasiyana ya zigawo zoyambira ndi zigawo zapansi, kuphatikiza matailosi opangidwa ndi vitrified ndi mayamwidwe otsika kwambiri, ndipo amakhala ndi kusinthasintha kwabwino, kuti athane ndi kupsinjika komwe kumabwera chifukwa cha kusiyana kwa kutentha, komanso kukhazikika kwabwino kwambiri, kulimba kwanthawi yayitali, kutsekeka kwanthawi yayitali, kutseguka kwanthawi yayitali, kutsekeka kwanthawi yayitali, kutsekeka kwanthawi yayitali, kutsekeka kwanthawi yayitali, kutsekereza nthawi yayitali komanso yocheperako. palibe chifukwa chonyowetsa matailosi m'madzi. Njira yomangayi ndiyosavuta kugwiritsa ntchito komanso yosavuta kuwongolera pakuwongolera kwabwino pamalowo.
