Txhim kho cov dej tuav: HPMC tuaj yeem txhim kho cov dej tuav ntawm cov mortar. Kev noj tshuaj tsawg dua ntawm HPMC tuaj yeem txhim kho cov dej tuav ntawm mortar. Piv txwv li, thaum qhov ntau npaum li cas yog 0.02%, cov dej tuav tau nce ntawm 83% mus rau 88%; Thaum cov koob tshuaj yog 0.2%, cov dej tuav tau nce mus txog 97%. Cov dej tuav tau zoo ua kom muaj dej txaus ntawm cov cement thiab txhim kho lub zog thiab kav ntev ntawm mortar.
Txhim kho kev ua haujlwm: HPMC tuaj yeem ua rau cov mortar pom zoo dua nyob rau hauv qis shear quab yuam, ua kom yooj yim rau kev thov thiab qib; Thaum nyob rau hauv siab shear quab yuam, lub mortar qhia ntau dua viscosity, tiv thaiv sagging thiab ntws. . Qhov tshwj xeeb thixotropy no ua rau cov mortar smoother thaum lub sij hawm tsim kho, txo kev tsim kho nyuaj thiab kev siv zog.
Txhim kho kev ua haujlwm tawg: Los ntawm kev ua kom cov elastic modulus thiab toughness ntawm mortar, HPMC tuaj yeem txo qhov tshwm sim ntawm cov kab nrib pleb, txhim kho qhov tawg tsis kam ntawm mortar, thiab txuas ntxiv nws lub neej kev pab cuam.
Ua kom muaj zog flexural: HPMC nce lub zog flexural ntawm mortar los ntawm kev ntxiv dag zog rau cov matrix thiab txhim kho kev sib txuas ntawm cov khoom. Qhov no yuav ua rau kom muaj zog tiv thaiv sab nraud thiab ua kom muaj kev ruaj ntseg ntawm lub tsev.
Txhim kho kev sib raug zoo zog: HPMC tsim ib zaj duab xis nyias nyob ib ncig ntawm cov khoom, txhim kho kev sib cuam tshuam ntawm mortar thiab substrate. Qhov no txhim kho adhesion ua kom muaj kev sib raug zoo, txo qhov kev pheej hmoo ntawm delamination lossis tsis ua haujlwm.
Txhim kho durability: Qhov sib ntxiv ntawm HPMC tuaj yeem tsim cov khoom sib zog, nrog qhov hnyav ntawm 11.76%. Qhov tsis zoo no feem ntau pab nrog thermal rwb thaiv tsev, txo cov khoom siv hluav taws xob los ntawm 30% thaum tuav cov cua sov ntawm kwv yees li 49W thaum raug tib lub cua sov. Qhov tsis kam mus rau tshav kub hloov mus los ntawm lub vaj huam sib luag sib txawv nrog tus nqi ntawm HPMC ntxiv, nrog rau kev koom ua ke siab tshaj plaws ntawm cov khoom ntxiv uas ua rau 32.6% nce hauv thermal resistance piv rau cov ntaub ntawv sib xyaw.
Txo Shrinkage thiab Cracking: Shrinkage thiab cracking yog ib qho kev sib tw hauv kev siv tshuaj khib nyiab, ua rau muaj kev cuam tshuam ntev. HPMC tsim cov matrix hloov tau nyob rau hauv lub mortar, txo cov kev ntxhov siab sab hauv thiab txo qhov tshwm sim ntawm shrinkage tawg.
Txhim kho cov dej tsis kam thiab impermeability: Hauv cov phab ntsa qhuav thiab caulk, HPMC txhim kho cov dej tsis kam thiab impermeability, tswj kev ruaj ntseg hauv qhov chaw ntub dej thiab ncua lub neej ntawm cov khoom.
Txhim kho khov-thaw tsis kam: Vim nws cov dej tuav tau zoo thiab kev ua haujlwm tawg, HPMC tuaj yeem tswj xyuas kev ua haujlwm ruaj khov hauv qhov chaw huab cua, ua kom muaj kev tsim kho zoo thiab ua haujlwm ntawm mortar.
Txhim kho tensile bonding lub zog: HPMC kuj tseem tuaj yeem ua rau muaj zog-shear bonding zog ntawm mortar. Ntxiv 0.2% HPMC tuaj yeem ua kom lub zog sib txuas ntawm mortar los ntawm 0.72MPa rau 1.16MPa.
HPMC muaj cov txiaj ntsig tseem ceeb hauv kev txhim kho cov kav dej ntawm cov mortar. Nws tuaj yeem txhim kho cov dej tuav ntawm mortar, txhim kho kev ua haujlwm, txhim kho kev sib tsoo, txhim kho kev sib raug zoo, txhim kho durability, txo qis shrinkage thiab tawg, thiab txhim kho dej tsis kam thiab impermeability. khoom, txhim kho khov-thaw kuj thiab txhim kho tensile bonding zog. Cov khoom no ua rau HPMC yog ib qho tseem ceeb ntxiv rau kev txhim kho cov mortar durability.
