Zinthu zopangidwa ndi ufa wa polymer zomwe zimasungunukanso ndi ufa wosungunukanso m'madzi, womwe umagawidwa m'magulu awiri: ethylene/vinyl acetate copolymers, vinyl acetate/tertiary ethylene carbonate copolymers, acrylic copolymers, ndi zina zotero, ndi polyvinyl alcohol ngati colloid yoteteza. Ufa uwu ukhoza kusungunukanso mwachangu kukhala emulsion mutakhudzana ndi madzi. Chifukwa cha mphamvu yayikulu yomangirira komanso mawonekedwe apadera a ufa wa polymer womwe umasungunukanso, monga: kukana madzi, kapangidwe kake ndi kutentha, ndi zina zotero, mitundu yosiyanasiyana ya ntchito zawo ndi yayikulu kwambiri.
Makhalidwe a magwiridwe antchito
Ili ndi mphamvu yolimba kwambiri yolumikizirana, imawongolera kusinthasintha kwa matope ndipo imakhala ndi nthawi yayitali yotsegulira, imapatsa matopewo mphamvu yabwino kwambiri yolimbana ndi alkali, komanso imawongolera kuuma, mphamvu yopindika, kukana madzi, kusinthasintha komanso kukana kuwonongeka kwa matope. Kuwonjezera pa kapangidwe kake, ili ndi kusinthasintha kwakukulu mu matope opindika oletsa ming'alu.
Munda wofunsira
1. Dongosolo loteteza kutentha kwa khoma lakunja: Dothi loteteza: Onetsetsani kuti dothilo limalumikiza khoma ndi bolodi la EPS mwamphamvu. Konzani mphamvu ya ma bond. Kupaka pulasitala: kuonetsetsa kuti makina ali olimba, kukana ming'alu ndi kulimba kwa dongosolo loteteza kutentha, komanso kukana kugunda.
2. Chomatira cha matailosi ndi chothandizira kutsekereza matailosi: Chomatira cha matailosi: Chimapereka mphamvu yolimba kwambiri pa matope, ndipo chimapereka kusinthasintha kokwanira kuti chichepetse kutentha kwa ma coefficients osiyanasiyana a substrate ndi matailosi a ceramic. Chodzaza: Chimapangitsa kuti matope asalowerere ndikuletsa kulowerera kwa madzi. Nthawi yomweyo, chimakhala chomatira bwino m'mphepete mwa matope, kuchepa pang'ono komanso kusinthasintha.
3. Kukonzanso matailosi ndi putty yopaka matabwa: Kuonjezera kulimba kwa putty ndi mphamvu yomangirira pa zinthu zapadera (monga malo a matailosi, mosaic, plywood ndi malo ena osalala), ndikuwonetsetsa kuti puttyyo ili ndi kusinthasintha kwabwino kuti ichepetse kuchuluka kwa madzi ofunikira.
Chachinayi, putty yamkati ndi yakunja ya khoma: onjezerani mphamvu yolumikizirana ya putty kuti muwonetsetse kuti putty ili ndi kusinthasintha kwina kuti iteteze zotsatira za kupsinjika kosiyanasiyana kwa kukula ndi kupindika komwe kumachitika chifukwa cha zigawo zosiyanasiyana za maziko. Onetsetsani kuti putty ili ndi kukana kukalamba, kukana kuzizira komanso kukana chinyezi.
5. Sitima yodziyimira payokha: onetsetsani kuti simenti yolimba ya sitimayo ikufanana komanso kuti siikugwedezeka ndi kusweka. Sinthani kukana kutopa, mphamvu yomangira, komanso mgwirizano wa sitimayo.
6. Cholumikizira cholumikizira: onjezerani mphamvu pamwamba pa chogwirira ndikuwonetsetsa kuti chogwiriracho chikugwirizana.
7. Mtondo wosalowa madzi wochokera ku simenti: onetsetsani kuti chophimba cha matope chikugwira ntchito bwino popanda madzi, ndipo nthawi yomweyo khalani ndi khoma labwino pamwamba pa nthaka kuti muwongolere mphamvu yopondereza ndi yopindika ya matope.
8. Konzani matope: onetsetsani kuti kuchuluka kwa matope ndi zinthu zoyambira zikugwirizana, ndikuchepetsa kuchuluka kwa elasticity ya matope. Onetsetsani kuti matopewo ali ndi mphamvu yotha kuletsa madzi, mpweya wabwino komanso kumatirira mokwanira.
9. Simenti yopaka pulasitala: imathandiza kusunga madzi. Imachepetsa kutaya madzi ku zinthu zofewa. Imathandiza kuti ntchito yomanga ikhale yosavuta komanso imathandiza kuti ntchito iyende bwino.
Ubwino
Sichifunika kusungidwa ndi kunyamulidwa ndi madzi, zomwe zimachepetsa ndalama zoyendera; nthawi yayitali yosungira, antifreeze, yosavuta kusunga; kulongedza pang'ono, kulemera kopepuka, kosavuta kugwiritsa ntchito; ikhoza kusakanizidwa ndi ma hydraulic binders kuti apange utomoni wopangidwa wosinthidwa. Chosakaniza choyambirira chingagwiritsidwe ntchito powonjezera madzi okha, zomwe sizimangopewa zolakwika pakusakaniza pamalo omanga, komanso zimathandizira chitetezo cha magwiridwe antchito a chinthucho.
