Mortar additive HPMC

Hydroxypropylmethylcellulose (HPMC) yog ib qho tshuaj mortar additive hauv kev tsim kho.Nws yog hloov kho cellulose ether muab los ntawm ntuj polymers, feem ntau yog cellulose.Muaj nyob rau hauv hmoov daim ntawv, HPMC yog yooj yim dispersed nyob rau hauv dej los tsim ib tug colloidal tov.

Thaum ntxiv rau mortar lossis cement-based mixes, HPMC muaj ntau yam khoom muaj txiaj ntsig:

Kev tuav dej: HPMC ua raws li tus neeg saib xyuas dej, tso cai rau lub mortar khaws nws txoj haujlwm tau ntev dua.Qhov no yog tshwj xeeb tshaj yog pab tau nyob rau hauv kub thiab qhuav ib puag ncig uas ceev ceev evaporation ntawm noo noo yuav ua rau lub mortar kom qhuav ntxov ntxov.

Txhim Kho Kev Ua Haujlwm Zoo: Los ntawm kev ua kom zoo sib xws thiab cov yas ntawm cov tshuaj khib nyiab, HPMC txhim kho nws txoj kev ua haujlwm, ua kom yooj yim rau kev sib tov, sib kis thiab siv.Qhov no txhim kho tag nrho cov yam ntxwv tuav ntawm lub mortar.

Enhanced Adhesion: HPMC txhim kho qhov adhesion ntawm mortar thiab ntau yam substrates xws li pob zeb, cib thiab pobzeb.Qhov no txhawb kev sib raug zoo zoo dua thiab txo qhov kev pheej hmoo ntawm delamination lossis sib cais.

Txo Sag: HPMC pab tiv thaiv cov mortar los ntawm sagging los yog collapsing thaum siv rau ntawm ntsug nto, kom ntseeg tau zoo dua kev pab them nqi thiab txo qhov yuav tsum tau rau rework.

Lub Sijhawm Qhib Ntxiv: Qhov sib ntxiv ntawm HPMC ua rau lub sijhawm qhib ntawm lub mortar, yog li txuas ntxiv lub qhov rais ntawm lub sijhawm uas cov mortar tseem ua haujlwm tau zoo thiab sib koom ua ke.Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov haujlwm loj lossis cov haujlwm nyuaj uas xav tau sijhawm ntxiv los thov.

Txhim kho Durability: HPMC ua kom lub zog tag nrho ntawm cov mortar los ntawm kev txo qis, tawg thiab dej permeability.Nws txhim khu kev sib koom ua ke thiab kev ncaj ncees ntawm cov mortar, ua rau cov khoom kawg muaj zog thiab ruaj khov dua.

Tus nqi pes tsawg ntawm HPMC xav tau nyob rau hauv ib lub mortar formulation yuav txawv nyob ntawm seb yam xws li cov khoom xav tau, ib puag ncig thiab hom mortar siv.Nws raug nquahu kom ua raws li cov chaw tsim khoom cov lus qhia thiab cov ntaub ntawv qhia txog kev siv tshuaj thiab cov lus qhia siv.

Zuag qhia tag nrho, HPMC yog ib qho khoom siv ntau yam ntxiv uas txhim kho kev ua haujlwm ntawm cov mortar thiab cement-based mix, txhim kho kev ua haujlwm, adhesion thiab durability.
