Ubudlelwano phakathi kwe-HPMC ne-tile grout

1. Isingeniso se-Hydroxypropyl Methylcellulose (HPMC)

IHydroxypropyl Methylcellulose (HPMC)iyi-ether engeyona ionic cellulose esetshenziswa kabanzi ezintweni zokwakha, imithi, ukudla, amakhemikhali nsuku zonke nezinye izimboni. Yenziwe ngezinto ze-polymer zemvelo ngokuguqulwa kwamakhemikhali futhi inokuncibilika kahle kwamanzi, ukujiya, ukugcinwa kwamanzi, ukwakhiwa kwefilimu kanye nokuzinza kokumiswa. Emkhakheni wezinto zokwakha, i-HPMC isetshenziselwa ikakhulukazi udaka olomile, i-tile adhesive, i-putty powder, i-grout, njll. ukuthuthukisa ukusebenza kokwakhiwa nokuthuthukisa ikhwalithi yomkhiqizo wokugcina.

2. Umsebenzi nokubunjwa kwe-tile grout

I-tile grout yinto esetshenziselwa ukugcwalisa igebe phakathi kwamathayili, anemisebenzi yokuthuthukisa ubuhle, ukungangeni kwamanzi, ukumelana nesikhutha kanye nokumelana nokuqhekeka. Izingxenye eziyinhloko ze-grout zihlanganisa:
Usimende noma i-resin: njengento eyinhloko yokubopha, enikeza amandla nobulukhuni;
Isigcwalisi: njengesihlabathi se-quartz, i-calcium carbonate, njll., esetshenziselwa ukuthuthukisa ukumelana nokugqoka kanye nokuzinza kwesakhiwo se-grout;
Izengezo: ezifana ne-HPMC, i-latex powder, i-pigment, njll., enikeza i-grout ukusebenza kahle kokwakhiwa, ukugcinwa kwamanzi, ukumelana nokuncipha nokuqina.

3. Iqhaza le-HPMC ku-tile grout

Nakuba inani le-HPMC elingezwe ku-tile grout lincane, indima yalo ibalulekile, ibonakala ikakhulukazi kulezi zici ezilandelayo:

(1) Ukugcina amanzi

I-HPMC inomthamo omuhle kakhulu wokugcina amanzi. Ku-grout, ingabambezela ukuhwamuka kwamanzi, ithuthukise ukusebenza kahle kwe-hydration kasimende, i-hydrate ngokugcwele usimende, ithuthukise ukunamathela namandla e-grout, futhi inciphise ukuqhekeka kanye nempushana okubangelwa ukulahlekelwa kwamanzi ngokushesha.

(2) Thuthukisa ukusebenza komsebenzi wokwakha

I-HPMC ingathuthukisa i-rheology ye-grout, yenze i-slurry ibe lula ukuyinyakazisa futhi isetshenziswe, ithuthukise ukushelela kokwakhiwa, futhi igweme izinkinga ezifana nokuhlanganisa kanye nokugoqa ngesikhathi sokwakhiwa. Ngaphezu kwalokho, inganweba isikhathi sokwakha, inikeze izisebenzi isikhathi esengeziwe sokulungisa nokuthuthukisa izinga lokwakha.

(3) Vimbela ukuqhekeka nokushwabana

I-grout ijwayele ukushwabana nokuqhekeka ngenxa yokuhwamuka kwamanzi ngokushesha phakathi nenqubo yokuqina. Umthelela wokugcina amanzi we-HPMC unganciphisa ngempumelelo le ngozi, ulondoloze ukuzinza kwesakhiwo se-grout, unciphise ukukhiqizwa kwama-microcracks, futhi uthuthukise umphumela wokugaya.

(4) Thuthukisa impahla elwa nokucwila

Ngesikhathi sokwakhiwa okuqondile (okufana nokubhoboza odongeni), i-ejenti ye-caulking ijwayele ukushelela phansi noma ukucwila ngenxa yamandla adonsela phansi. I-HPMC ilungisa izakhiwo ze-rheological ze-ejenti ye-caulking futhi ithuthukise i-thixotropy yayo, ukuze igcine i-viscosity ephezulu esimweni esimile, futhi ibuyisele uketshezi ngesikhathi sokunyakaziswa noma ukwakhiwa kwemisebenzi, ngaleyo ndlela inciphise inkinga ye-sag futhi ithuthukise ukusebenza kahle kokwakhiwa.

(5) Thuthukisa ukumelana nokuncibilika kweqhwa kanye nokumelana nesimo sezulu

I-HPMC ingathuthukisa ikhono le-ejenti yokufaka i-caulking ukumelana nemijikelezo yokuncibilika kweqhwa, ukuze ihlale izinzile ezindaweni ezisezingeni eliphansi futhi akulula ukuthi ibe yimpuphu noma iwe. Ngesikhathi esifanayo, ingakwazi futhi ukuthuthukisa ukumelana nesimo sezulu se-agent caulking, ukuze ikwazi ukugcina ukusebenza kahle ngaphansi kwezimo ezinzima ezifana nomswakama kanye nemisebe ye-ultraviolet, futhi yandise impilo yayo yesevisi.

4. Izinto ezithinta ukusebenza kwe-HPMC

Amapharamitha afana nesisindo samangqamuzana e-HPMC, izinga lokushintsha, kanye ne-viscosity kuzothinta ukusebenza kokugcina kwe-ejenti yokukhohlakala. Ngokuvamile:
I-viscosity ephakeme i-HPMC inganikeza ukujiya okunamandla nokugcinwa kwamanzi, kodwa ingase inciphise uketshezi;
Izinga elifanele lokushintsha (okuqukethwe kwe-methoxy ne-hydroxypropyl) kungathuthukisa ukuncibilika futhi kuqinisekise ukufana kwe-agent caulking;
Umthamo ofanelekile ungathuthukisa ukusebenza kanye nokuqina kwe-ejenti ye-caulking, kodwa umthamo oweqile ungaholela ku-viscosity eyeqile, kuthinte ukwakhiwa nokuthuthukiswa kwamandla.

Njengesengezo esiyisihluthulelo kuma-ejenti we-caulking tile,I-HPMCikakhulukazi ithuthukisa ikhwalithi yama-agent e-caulking ngokwenza ngcono ukugcinwa kwamanzi, ukuthuthukisa ukusebenza kokwakhiwa, kanye nokuthuthukisa ukumelana nokuncipha nokuhlala isikhathi eside. Ukukhetha okunengqondo kwezinhlobo nemithamo ye-HPMC kungathuthukisa ukusebenza kwama-ejenti abambezelayo, kuqinisekise ukwakhiwa okushelelayo, futhi kuthuthukise imiphumela yokugcina yokuhlobisa neyokuvikela. Ngakho-ke, ekwakhiweni kokwakhiwa kwama-ejenti afaka amathayela, ukukhethwa nokusebenzisa i-HPMC kubalulekile.
