Cov hmoov polymer uas yaj tau dua tshiabyog cov khoom siv ntxiv tseem ceeb rau cov hmoov qhuav uas tau sib xyaw ua ke xws li cov cement lossis gypsum.
Cov hmoov latex uas tawg tau yog cov polymer emulsion uas tau txau thiab sib sau ua ke los ntawm 2um thawj zaug los ua cov khoom me me ntawm 80 ~ 120um. Vim tias cov nplaim ntawm cov khoom me me tau coated nrog cov hmoov inorganic, tawv-resistant-structure, peb tau txais cov hmoov polymer qhuav. Lawv yooj yim nchuav lossis hnab rau khaws cia hauv cov tsev rau khoom. Thaum cov hmoov sib xyaw nrog dej, cement lossis gypsum-based mortar, nws tuaj yeem tawg dua, thiab cov khoom me me (2um) hauv nws yuav rov ua dua rau lub xeev sib npaug rau cov latex thawj, yog li nws hu ua cov hmoov latex tawg tau.
Nws muaj kev tawg zoo dua, rov tawg ua emulsion thaum kov dej, thiab muaj cov khoom siv tshuaj zoo ib yam li cov emulsion qub. Los ntawm kev ntxiv cov hmoov polymer uas tawg tau dua rau hauv cov cement-based lossis gypsum-based dry powder ready-mixed mortar, ntau yam khoom ntawm mortar tuaj yeem txhim kho,
Kev siv hauv kev tsim kho
1 Lub Tshuab Rwb Thaiv Phab Ntsa Sab Nraud
Nws tuaj yeem ua kom muaj kev sib txuas zoo ntawm cov mortar thiab polystyrene board thiab lwm yam substrates, thiab nws tsis yooj yim rau hollow thiab poob tawm. Kev ywj pheej zoo dua, kev cuam tshuam tsis kam thiab txhim kho lub zog tawg.
2 daim nplaum pobzeb
Muab kev sib txuas lus zoo rau cov mortar, muab qhov yooj ywm txaus rau cov mortar kom nruj cov coefficients thermal expansion ntawm cov substrate thiab pobzeb.
3 lub caulk
Cov hmoov polymer uas tawg tau dua ua rau cov mortar tsis nkag tau thiab tiv thaiv dej kom tsis txhob nkag mus. Tib lub sijhawm, nws muaj kev sib txuas zoo nrog ntug ntawm cov pobzeb, tsis tshua muaj kev ntsws thiab yooj ywm.
4 lub interface mortar
Nws tuaj yeem kaw qhov sib txawv ntawm lub substrate zoo dua, txo qhov nqus dej ntawm phab ntsa, txhim kho lub zog ntawm lub substrate, thiab xyuas kom meej tias cov mortar lo rau.
5 Cov tshuaj nplaum hauv pem teb uas siv tau rau tus kheej
Txhim kho qhov tawg tsis kam ntawm tus kheej-leveling, nce lub zog sib txuas nrog cov txheej hauv qab, txhim kho qhov cohesion, tawg tsis kam thiab khoov lub zog ntawm cov mortar.
6 daim ntaub thaiv dej tsis muaj dej
Cov hmoov latex uas yaj tau dua tuaj yeem txhim kho kev ua haujlwm; ntxiv rau qhov ua kom dej khaws cia; txhim kho kev noo ntawm cov cement; txo qhov elastic modulus ntawm cov mortar thiab txhim kho kev sib raug zoo nrog cov txheej hauv paus. Txhim kho qhov ceev ntawm cov mortar, ua kom muaj kev ywj pheej, tiv thaiv kev tawg lossis muaj peev xwm txuas.
7 kho cov tshuaj khib
Xyuas kom cov mortar lo rau thiab ua kom qhov chaw kho kom ruaj khov. Qhov elastic modulus qis dua ua rau nws tiv taus kev ntxhov siab heev.
8 daim nplaum
Txo qhov elastic modulus ntawm cov mortar, txhim kho qhov sib xws nrog cov txheej hauv paus, ua rau muaj kev ywj pheej, tiv thaiv kev tawg, txhim kho qhov tsis kam rau cov hmoov poob, yog li ntawd cov putty muaj qee qhov tsis kam thiab tsis kam noo noo, uas tuaj yeem them rov qab qhov puas tsuaj ntawm kev ntxhov siab kub.
