Ubudlelwano phakathi kwe-HPMC ne-Tile Grout

1. Isingeniso se-Hydroxypropyll methylcellulose (HPMC)

I-Hydroxypropyl methylcellulose (HPMC)Ingabe i-ether engeyona eye-cellulose ether esetshenziswa kabanzi ezintweni zokwakha, umuthi, ukudla, amakhemikhali nsuku zonke nezinye izimboni. Kwenziwe ngezinto zemvelo ze-polymer ngokusebenzisa ukuguqulwa kwamakhemikhali futhi kune-solubility enhle yamanzi, ukuqina, ukugcinwa kwamanzi, ukuqina kwefilimu nokumiswa nokuqina. Emkhakheni wezinto zokwakha, i-HPMC isetshenziswa ikakhulukazi ku-fortar owomile, ithangiseli enamathela, i-putty powder, njll. Ukwenza ngcono ukusebenza kokwakha futhi kuthuthukise ikhwalithi yomkhiqizo wokugcina.

2. Umsebenzi nokwakheka kwe-tile grout

I-Tile Grout iyinto esetshenziselwa ukugcwalisa igebe phakathi kwamathayili, elinemisebenzi yokuthuthukisa ama-aesthetics, angangeni manzi, ukumelana isikhutha kanye nokumelana nokuqhekeka. Izici eziphambili ze-grout zifaka:
Usimende noma i-resin: njengezinto ezibophayo ezinkulu, ukunikeza amandla nobulukhuni;
Filler: njenge-quartz sand, calcium carbonate, njll.
Izengezo: njenge-HPMC, i-latex powder, i-pigment, njll.

3. Iqhaza le-HPMC in Tile Grout

Yize inani le-HPMC elingezwe ku-tile grout lincane, indima yayo ibalulekile, ikakhulukazi kuboniswa ezintweni ezilandelayo:

(1) Ukugcinwa kwamanzi

I-HPMC inomthamo omuhle kakhulu wokugcina amanzi. Ku-grout, kungabambezela ukuhwamuka kwamanzi, kuthuthukise ukusebenza kahle kwamanzi kasimende, i-hydrate ngokuphelele usimende, uthuthukise ukunamathela namandla we-grout, futhi unciphise ukuqhekeka okubangelwa ukulahleka kwamanzi okusheshayo.

(2) Thuthukisa ukusebenza kokwakha

I-HPMC ingathuthukisa i-Rheology ye-grout, yenza ama-slurry abe lula ukuvusa futhi asebenze, athuthukise ubushelelezi bokwakha, futhi agweme izinkinga ezinjenge-agglomeration kanye nokugcwala ngesikhathi sokwakha. Ngaphezu kwalokho, kunganweba isikhathi sokwakha, ukunikeza abasebenzi isikhathi esithe xaxa sokushintsha kanye nokwenza ngcono ikhwalithi yokwakha.

(3) Vikela ukuqhekeka nokuqhekeka

I-grout ithambekele ekunciphiseni nasekuqhekekeni ngenxa yokuhwamuka ngokushesha kwamanzi ngesikhathi senqubo enzima. Ukutholwa kokugcinwa kwamanzi kwe-HPMC kunganciphisa ngempumelelo le ngozi, qhubeka nokuqina kwe-grout, ukunciphisa isizukulwane sama-microcracks, futhi uthuthukise umphumela wokucophelela.

(4) Ngcono impahla elwa nokuhlanza

Ngesikhathi sokwakhiwa okuqondile (okufana nodonga lwe-caulking), i-ejenti ye-caulking ithambekele ekuswele phansi noma i-sag ngenxa yokudonsela phansi. I-HPMC ilungisa izakhiwo ze-bherologi ze-ejenti ye-caulking futhi ithuthukise i-thixotropy yayo, ukuze igcine ukubonwa okuphezulu esimweni esijwayelekile, futhi ibuyise i-fluonity ngesikhathi sokuvusa noma ukunciphisa inkinga ye-sag kanye nokwenza ngcono ukusebenza kwe-sag kanye nokwenza ngcono ukusebenza kwe-sag kanye nokwenza ngcono ukusebenza kokwakha.

(5) Thuthukisa ukumelana kwe-freeze-thaw kanye nokumelana nesimo sezulu

I-HPMC ingathuthukisa amandla e-caulking agent ukumelana nemijikelezo ye-freeze-thaw, ukuze ihlale izinzile ezindaweni eziphansi zokushisa futhi akulula ukuwela noma ukuwa. Ngasikhathi sinye, futhi kungathuthukisa ukumelana nesimo sezulu se-caulking agent, ukuze kusakwazi ukugcina ukusebenza okuhle ngaphansi kwezimo ezinzima njengemisebe nemisebe yayo ye-ultraviolet, futhi yandise imisebe yayo yesevisi.

4. Izici ezithinta ukusebenza kwe-HPMC

Amapharamitha anjengesisindo se-hpmc sika-HPMC, izinga lokufaka esikhundleni, futhi i-viscosity izothinta ukusebenza kokugcina kwe-ejenti ye-caulking. Ngokuvamile khuluma:
I-Vissesity ephezulu i-HPMC ingahlinzeka ngokuqina okuqinile nokugcinwa kwamanzi, kepha inganciphisa uxhaso;
Izinga elifanele lokufakwa esikhundleni (okufakwayo kwe-methoxy kanye ne-hydroxyproppy) lingathuthukisa i-solubity futhi liqinisekise ukufana kwe-ejenti ye-caulking;
Umthamo ofanelekile ungakhulisa ukusebenziseka nokuqina kwe-ejenti ye-caulking, kepha umthamo owedlulele kungaholela ekuvulekekeni ngokweqile, okuthinta ukwakhiwa nokuthuthukiswa kwamandla.

Njengomkhulu osemqoka kuma-tile caulking agents,I-HPMCKakhulu kuthuthukisa ikhwalithi yama-caulking agents ngokwenza ngcono ukugcinwa kwamanzi, ukwenza ngcono ukusebenza kokwakha, kanye nokwenza ngcono ukumelana nokuqina. Ukukhetha okunengqondo kwezinhlobo ze-HPMC nemithamo kungakhulisa ukusebenza kwama-caulking agents, kuqinisekisa ukwakhiwa okubushelelezi, futhi kuthuthukise imiphumela yokugcina yokuhlobisa nemivivo. Ngakho-ke, ekwakhiweni okwakhiwa kwama-tile caulking agents, ukukhethwa kanye nokusetshenziswa kwe-HPMC kubalulekile.
