IHydroxypropylmethylcellulose (HPMC) yipolymer eguquguqukayo esetyenziswa kakhulu kushishino lokwakha. Yimathiriyeli engeyotyhefu, engenavumba, i-pH ezinzileyo eyenziwe ngokuzisa i-hydroxypropyl kunye namaqela e-methyl kwiselulosi yendalo. I-HPMC ifumaneka kwiindidi ngeendidi zamabakala kunye ne-viscosities eyahluka-hlukeneyo, ubungakanani bamasuntswana kunye namaqondo okutshintshwa. I-polymer e-soluble yamanzi enokuthi yenze i-gels kwiindawo eziphezulu kodwa ibe nefuthe elincinci okanye elingenalo kwi-rheology yamanzi kwiindawo eziphantsi. Eli nqaku lixoxa ngokusetyenziswa kwe-HPMC kwizinto ezahlukeneyo zokwakha.
Ukusetyenziswa kweHPMC ekutyatyekeni nasekunikezeleni
Ukwakhiwa kwezakhiwo kufuna iipropati eziphuculweyo zomgangatho weendonga, imigangatho kunye neesilingi. I-HPMC yongezwa kwi-gypsum kunye nezinto zokutyabeka ukunyusa ukusebenza kwazo kunye nokunamathela. I-HPMC iphucula ukuguda kunye nokuhambelana kodaka kunye nezixhobo zokutyabeka. Yandisa amandla okugcina amanzi emixube, evumela ukuba banamathele bhetele eludongeni okanye kwiindawo eziphantsi. I-HPMC ikwanceda ukuthintela ukushwabana nokuqhekeka ngexesha lokunyanga nokomisa, ukonyusa ukuqina kwengubo.
Ukusetyenziswa kwe-HPMC kwi-adhesive tile
Izinto zokuncamathelisa iithayile ziyinxalenye ebalulekileyo yeeprojekthi zokwakha zale mihla. I-HPMC isetyenziselwa ukunamathela kwiithayile ukuphucula ukubambelela kwabo, ukugcinwa kwamanzi kunye nokusebenza kokwakha. Ukongeza i-HPMC ekuqulunqweni kwe-adhesive kwandisa kakhulu ixesha elivulekileyo le-adhesive, ukunika abafakeli ixesha elingakumbi lokwenza uhlengahlengiso phambi kokuba iiseti zeetayile zisete. I-HPMC ikwanyusa ukuguquguquka kunye nokuqina kwe-bondline, ukunciphisa umngcipheko we-delamination okanye ukuqhekeka.
Ukusetyenziswa kwe-HPMC kwiikhompawundi zokuzilinganisa
Iikhompawundi zokuzilinganisa zisetyenziselwa ukulinganisa imigangatho kunye nokudala i-smooth, elinganayo indawo yokufakelwa kwezinto zomgangatho. I-HPMC yongezwa kwiikhompawundi zokuzilinganisa ukuphucula ukuhamba kwazo kunye neempawu zokulinganisa. I-HPMC inciphisa i-viscosity yokuqala yomxube, okwenza kube lula ukuyifaka kunye nokuphucula umgangatho. HPMC kwakhona kwandisa ukugcinwa kwamanzi umxube, ukuqinisekisa amandla bond ngcono phakathi imathiriyeli umgangatho kunye substrate.
Ukusetyenziswa kwe-HPMC kwi-caulk
I-Grout isetyenziselwa ukuzalisa izithuba phakathi kweetayile, ilitye lendalo okanye ezinye izinto zomgangatho. I-HPMC yongezwa kwikhompawundi edibeneyo yokuphucula ukusebenza kwayo yokwakha kunye nokuqina. I-HPMC ikwandisa i-viscosity yomxube, okwenza kube lula ukusabalalisa kunye nokunciphisa ukuncipha kunye nokuqhekeka kwezinto zokugcwalisa ngexesha lokunyanga. I-HPMC iphinda iphucule ukunamathela kwe-filler kwi-substrate, ukunciphisa amathuba okuba nezithuba ezizayo kunye nokuqhekeka.
HPMC kwiimveliso gypsum-based
Iimveliso ezisekelwe kwi-Gypsum, ezifana ne-plasterboard, iithayile zesilingi kunye neebhodi zokugquma, zisetyenziswa kakhulu kwishishini lokwakha. I-HPMC isetyenziswa kwiimveliso ezisekelwe kwigypsum ukuphucula ukusebenza kwazo, ukubeka ixesha kunye namandla. I-HPMC inciphisa imfuno yamanzi yokuqulunqwa, ivumela umxholo ophezulu wezinto eziqinileyo, okwandisa amandla kunye nokuqina kwemveliso egqityiweyo. I-HPMC iphinda iphucule ukunamathela phakathi kweengqungquthela ze-gypsum kunye ne-substrate, iqinisekisa ibhondi elungileyo.
ukuququmbela
IHydroxypropylmethylcellulose (HPMC) yipolymer eguquguqukayo esetyenziswa kwiintlobo ngeentlobo zezinto zokwakha. I-HPMC iphucula ukusebenza kwe-gypsum kunye nezinto zokutyabeka, i-adhesives tile, i-self-leveling compounds, i-grouts kunye neemveliso ezisekelwe kwi-gypsum. Ukusebenzisa i-HPMC kwezi zinto kuphucula ukuqhubekeka, ukunamathela, ukugcinwa kwamanzi kunye nokuqina. Ke, i-HPMC inceda ekudaleni izinto zokwakha ezomeleleyo, ezihlala ixesha elide, ezihlala ixesha elide ezihlangabezana neemfuno eziphezulu zoyilo lwangoku.
