Ubale pakati pa HPMC ndi tile grout

1. Mau oyamba a Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl Methylcellulose (HPMC)ndi non-ionic cellulose ether yomwe imagwiritsidwa ntchito kwambiri pomanga, mankhwala, chakudya, mankhwala a tsiku ndi tsiku ndi mafakitale ena. Zimapangidwa ndi zinthu zachilengedwe za polima pogwiritsa ntchito kusintha kwa mankhwala ndipo zimakhala ndi madzi abwino kusungunuka, kukhuthala, kusunga madzi, kupanga mafilimu ndi kukhazikika kwa kuyimitsidwa. Pazinthu zomangira, HPMC imagwiritsidwa ntchito makamaka mumatope owuma, zomatira matailosi, ufa wa putty, grout, etc.

2. Ntchito ndi kapangidwe ka tile grout

Tile grout ndi zinthu zomwe zimagwiritsidwa ntchito kudzaza kusiyana pakati pa matailosi, omwe ali ndi ntchito zopititsa patsogolo kukongola, kutetezedwa kwa madzi, kukana mildew ndi kukana ming'alu. Zigawo zazikulu za grout ndi:
Simenti kapena utomoni: monga chinthu chachikulu chomangira, kupereka mphamvu ndi kuuma;
Zodzaza: monga mchenga wa quartz, calcium carbonate, ndi zina zotero, zomwe zimagwiritsidwa ntchito popititsa patsogolo kukana komanso kukhazikika kwa grout;
Zowonjezera: monga HPMC, latex powder, pigment, ndi zina zotero, zomwe zimapatsa grout ntchito yabwino yomanga, kusunga madzi, kukana kwa shrinkage ndi kulimba.

3. Udindo wa HPMC mu tile grout

Ngakhale kuchuluka kwa HPMC yowonjezeredwa ku tile grout ndi yaying'ono, udindo wake ndi wofunikira, makamaka ukuwonekera pazinthu izi:

(1) Kusunga madzi

HPMC ili ndi mphamvu yabwino yosungira madzi. Mu grout, imatha kuchedwetsa kutuluka kwamadzi, kupititsa patsogolo mphamvu ya simenti, kuthira madzi okwanira simenti, kumamatira komanso kulimba kwa gwero, komanso kuchepetsa kusweka ndi ufa chifukwa cha kutayika kwamadzi mwachangu.

(2) Kupititsa patsogolo ntchito yomanga

HPMC imatha kupititsa patsogolo rheology ya grout, kupanga slurry kukhala kosavuta kugwedezeka ndikuyika, kukonza kusalala kwa zomangamanga, ndikupewa zovuta monga kuphatikizika ndi kugwedera pakumanga. Kuphatikiza apo, imatha kukulitsa nthawi yomanga, kupatsa ogwira ntchito nthawi yochulukirapo kuti asinthe ndikuwongolera ntchito yomanga.

(3) Pewani kusweka ndi kuchepa

The grout sachedwa kung'ambika ndi kusweka chifukwa cha nthunzi yofulumira ya madzi panthawi yowumitsa. Mphamvu yosungira madzi ya HPMC imatha kuchepetsa ngoziyi, kusunga kukhazikika kwa grout, kuchepetsa kubadwa kwa ma microcracks, ndikuwongolera momwe ma grouting amagwirira ntchito.

(4) Limbikitsani katundu woletsa kugwa

Pakumanga koyima (monga kutsekereza khoma), chowongolera chimakhala chotsika kapena kugwa chifukwa cha mphamvu yokoka. HPMC imasintha rheological katundu wa caulking wothandizila ndi bwino thixotropy, kotero kuti amakhala mkulu mamasukidwe akayendedwe mu malo amodzi boma, ndi kubwezeretsa fluidity pa yogwira mtima kapena yomanga ntchito, potero kuchepetsa sag vuto ndi kuwongolera yomanga Mwachangu.

(5) Limbikitsani kukana kuzizira komanso kukana nyengo

HPMC ikhoza kupititsa patsogolo luso la caulking kukana kuzizira kozizira, kuti likhalebe lokhazikika m'malo otentha komanso kuti likhale losavuta kupukuta kapena kugwa. Panthawi imodzimodziyo, imatha kupititsa patsogolo kukana kwa nyengo ya caulking, kotero kuti ikhoza kukhalabe ndi ntchito yabwino pansi pa zovuta monga chinyezi ndi cheza cha ultraviolet, ndikuwonjezera moyo wake wautumiki.

4. Zinthu zomwe zimakhudza magwiridwe antchito a HPMC

Ma parameters monga HPMC's molecular weight, degree of substitution, ndi viscosity zidzakhudza ntchito yomaliza ya caulking agent. Nthawi zambiri:
Apamwamba mamasukidwe akayendedwe HPMC angapereke amphamvu thickening ndi kusunga madzi, koma kuchepetsa fluidity;
Mlingo woyenera wolowa m'malo (methoxy ndi hydroxypropyl zili) zitha kusintha kusungunuka ndikuwonetsetsa kufanana kwa woyambitsa;
Mlingo woyenera ukhoza kupititsa patsogolo ntchito ndi kulimba kwa wothandizira, koma mlingo wochuluka ukhoza kubweretsa kukhuthala kwakukulu, zomwe zimakhudza kumanga ndi kukula kwa mphamvu.

Monga chowonjezera chachikulu mu ma caulking agents,Mtengo wa HPMCmakamaka amawongolera mtundu wa ma caulking agents popititsa patsogolo kusungidwa kwa madzi, kupititsa patsogolo ntchito yomanga, komanso kukulitsa kulimba kwa shrinkage ndi kulimba. Kusankha koyenera kwa mitundu ndi Mlingo wa HPMC kumatha kukhathamiritsa magwiridwe antchito a ma caulking agents, kuonetsetsa kuti zomangamanga bwino, ndikuwonjezera kukongoletsa komaliza ndi chitetezo. Chifukwa chake, pakupanga mapangidwe a othandizira opangira matayala, kusankha ndi kugwiritsa ntchito HPMC ndikofunikira.
