Ubudlelwane phakathi kwe-HPMC kunye ne-tile grout

1. Intshayelelo ngeHydroxypropyl Methylcellulose (HPMC)

IHydroxypropyl Methylcellulose (HPMC)i-ether ye-cellulose engekho i-ionic esetyenziswa ngokubanzi kwizinto zokwakha, amayeza, ukutya, iikhemikhali zemihla ngemihla kunye namanye amashishini. Yenziwe ngezinto zepolymer zendalo ngokuguqulwa kweekhemikhali kwaye inokunyibilika kakuhle kwamanzi, ukutyeba, ukugcinwa kwamanzi, ukwenza ifilimu kunye nokuzinza kokumiswa. Kwintsimi yezinto zokwakha, i-HPMC isetyenziselwa kakhulu udaka olomileyo, i-tile adhesive, i-putty powder, i-grout, njl.

2. Umsebenzi kunye nokubunjwa kwe-tile grout

I-tile grout yimpahla esetyenziselwa ukuzalisa i-gap phakathi kweetayile, enemisebenzi yokuphucula i-aesthetics, i-waterproofness, ukumelana ne-mildew kunye ne-crack resistance. Amacandelo aphambili e-grout aquka:
I-samente okanye i-resin: njengeyona nto ibalulekileyo yokudibanisa, ukunika amandla kunye nobunzima;
Ukuzalisa: njengesanti ye-quartz, i-calcium carbonate, njl., esetyenziselwa ukuphucula ukunyanzeliswa kokugqoka kunye nokuzinza kwesakhiwo se-grout;
Izongezo: ezifana ne-HPMC, i-latex powder, i-pigment, njl., enika i-grout ukusebenza kakuhle kolwakhiwo, ukugcinwa kwamanzi, ukuxhathisa ukushwabana kunye nokuqina.

3. Indima ye-HPMC kwi-tile grout

Nangona isixa se-HPMC esongeziweyo kwi-tile grout sincinci, indima yayo ibalulekile, ikakhulu ibonakaliswa kule miba ilandelayo:

(1) Ukugcinwa kwamanzi

I-HPMC inomthamo ogqwesileyo wogcino lwamanzi. Kwi-grout, inokulibazisa ukukhuphuka kwamanzi, ukuphucula ukusebenza kakuhle kwe-samente, i-samente i-hydrate ngokupheleleyo, iphucule ukubambelela kunye namandla e-grout, kunye nokunciphisa ukuqhekeka kunye nomgubo obangelwa ukulahleka kwamanzi ngokukhawuleza.

(2) Ukuphucula ukusebenza kolwakhiwo

I-HPMC inokuphucula i-rheology ye-grout, yenza i-slurry ibe lula ukuyishukumisa kwaye ifake, iphucule ukuguda kolwakhiwo, kwaye iphephe iingxaki ezinje nge-agglomeration kunye ne-sagging ngexesha lokwakha. Ukongezelela, inokwandisa ixesha lokwakha, inike abasebenzi ixesha elingakumbi lokulungelelanisa nokuphucula umgangatho wokwakha.

(3) Thintela ukuqhekeka kunye nokuncipha

I-grout ixhomekeke kwi-shrinkage kunye nokuqhekeka ngenxa yokunyuka ngokukhawuleza kwamanzi ngexesha lenkqubo yokuqina. Umphumo wokugcinwa kwamanzi we-HPMC unokunciphisa ngokufanelekileyo lo mngcipheko, ugcine uzinzo lwesakhiwo se-grout, ukunciphisa ukuveliswa kwe-microcracks, kunye nokuphucula umphumo we-grouting.

(4) Ukuphucula ipropathi echasayo

Ngexesha lolwakhiwo oluthe nkqo (okufana ne-caulking eludongeni), i-agent ye-caulking ijwayele ukutyibilika phantsi okanye i-sag ngenxa yobunzima. I-HPMC ilungisa iimpawu ze-rheological ze-agent ye-caulking kwaye iphucula i-thixotropy yayo, ukwenzela ukuba igcine i-viscosity ephezulu kwi-static state, kwaye ibuyisela ulwelo ngexesha lokuvuselela okanye ukwakhiwa kwemisebenzi, ngaloo ndlela inciphisa ingxaki ye-sag kunye nokuphucula ukusebenza kakuhle kolwakhiwo.

(5) Phucula ukumelana nokunyibilika komkhenkce kunye nokumelana nemozulu

I-HPMC inokuphucula ukukwazi kwe-arhente ye-caulking ukuxhathisa imijikelo yokuqhaqha, ukuze ihlale izinzile kwiindawo eziphantsi zobushushu kwaye akukho lula ukuba ngumgubo okanye ukuwa. Kwangaxeshanye, inokwandisa ukumelana nemozulu ye-agent caulking, ukuze ikwazi ukugcina ukusebenza kakuhle phantsi kweemeko ezinzima ezifana nokufuma kunye nemitha ye-ultraviolet, kwaye yandise ubomi bayo benkonzo.

4. Izinto ezichaphazela ukusebenza kwe-HPMC

Iiparameters ezifana ne-HPMC ye-molecular weight, i-degree of substitution, kunye ne-viscosity iya kuchaphazela ukusebenza kokugqibela kwe-arhente ye-caulking. Ukuthetha jikelele:
I-viscosity ephezulu ye-HPMC inokubonelela ngokutyeba okunamandla kunye nokugcinwa kwamanzi, kodwa inokunciphisa ukumanzi;
Iqondo elifanelekileyo lokutshintshwa (i-methoxy kunye nomxholo we-hydroxypropyl) unokuphucula ukunyibilika kunye nokuqinisekisa ukufana kwe-agent agent;
Idosi efanelekileyo inokwandisa ukusebenza kunye nokuqina kwe-arhente ye-caulking, kodwa idosi egqithisileyo inokukhokelela kwi-viscosity egqithisileyo, echaphazela ukwakhiwa kunye nophuhliso lwamandla.

Njengesongezo esiphambili kwii-agent zokutshiza iithayile,HPMCubukhulu becala iphucula umgangatho we-caulking agents ngokuphucula ukugcinwa kwamanzi, ukuphucula ukusebenza kolwakhiwo, kunye nokuphucula ukuxhathisa kunye nokuqina. Ukukhetha okunengqiqo kweentlobo ze-HPMC kunye needosi kunokwandisa ukusebenza kwee-caulking agents, ukuqinisekisa ukwakhiwa okugudileyo, kunye nokuphucula iziphumo zokugqibela zokuhombisa kunye nokukhusela. Ngoko ke, ekuqulunqweni koyilo lwee-agent ze-tile caulking, ukukhethwa kunye nokusetyenziswa kwe-HPMC kubalulekile.
