IHydroxypropylmethylcellulose (HPMC) yikhompawundi esetyenziswa kakhulu kushishino lokwakha. Umsebenzi wayo oyintloko kukuphucula iimpawu ezisebenzayo zezinto ezifana nodaka kunye nekhonkrithi. Esinye sezicelo ze-HPMC kukuzilinganisa kwegypsum, okubenempembelelo enkulu kushishino lokwakha.
I-plaster yokubeka i-self-leveling yimathiriyeli yomgangatho ophezulu ekulula ukuyifaka kwaye ingafakwa phezu kwekhonkrithi okanye imigangatho emidala. Lukhetho oludumileyo lolwakhiwo lwentengiso kunye neendawo zokuhlala ngenxa yokusebenza kwayo okuphezulu kunye nokuqina. Umceli mngeni ophambili kwi-self-leveling plaster application kukugcina umgangatho kunye nokuhambelana kwezinto ngexesha lokulungiselela nokufakwa. Apha kulapho HPMC iza kudlala.
I-Hydroxypropyl methylcellulose yi-thickener yokwenziwa eyongezwa kwi-gypsum-based self-leveling mixes ukuze kuqinisekiswe ukusasazeka komxube. Kwakhona kunceda ukulawula i-viscosity kunye nokugcina umgangatho wezinto eziphathekayo. I-HPMC sisithako esibalulekileyo kwimixube yegypsum yokuzinza njengoko izinzisa umxube, iqinisekisa ukuba ulwahlulo alwenzeki kwaye luphucula amandla okudibanisa umxube.
Inkqubo yokusetyenziswa kwe-gypsum yokuzimela ibandakanya ukuxuba i-gypsum kunye ne-HPMC kunye namanzi. Amanzi asebenza njengomthwali we-HPMC, eqinisekisa ukusasazwa kwawo ngokulinganayo kumxube. I-HPMC yongezwa kumxube kwizinga le-1-5% yobunzima obomileyo be-gypsum, kuxhomekeke kukuqina okufunwayo kunye nokusetyenziswa kokuphela kwezinto.
Kukho iinzuzo ezininzi zokongeza i-HPMC kumxube wodaka ozilinganisayo. Yandisa ukuqina kwezinto ngokwandisa amandla ayo kunye nokuchasana namanzi, iikhemikhali kunye ne-abrasion. Ukongeza, i-HPMC inyusa ukuguquguquka kwezinto, ivumela ukuba iqhelane nokutshintsha kobushushu kunye nokufuma. Oku kuthintela iintanda, kunciphisa inkunkuma kunye nokuphucula i-aesthetics yomgangatho wakho.
I-Hydroxypropyl methylcellulose inokuthi isebenze njengomgqugquzeli wokubambelela ngokunyusa amandla ebhondi yegypsum yokuzimela kwi-substrate. Xa umxube usetyenziswa, i-HPMC iqinisekisa ukuba umxube unamathela kwi-substrate, wenze i-bond esisigxina kunye neqinile. Oku kuphelisa imfuno yokudibanisa oomatshini, ukugcina ixesha kunye nemali ngexesha lofakelo.
Olunye uncedo lwe-HPMC kwi-gypsum-based self-leveling ligalelo layo ekuzinzeni kokusingqongileyo kushishino lokwakha. I-HPMC ihambelana nokusingqongileyo kwaye kulula ukuyilahla, iyenza ibe yindlela ekhuselekileyo nezinzileyo kwezinye iikhompawundi zemichiza.
I-Hydroxypropyl methylcellulose (HPMC) ibonakalise ukuba yinto ebalulekileyo kwi-gypsum-based self-leveling applications. Ngokufaka isandla ekungqineni, umgangatho kunye nokufana komxube, i-HPMC iphucula ukuqina kunye nobuhle bezinto eziphathekayo. Izibonelelo zayo zokomelezwa kwamandla ebhondi kunceda ukonga ixesha kunye nemali yoshishino. Ukongeza, ukusetyenziswa kwe-HPMC kukhuthaza ukuzinza kokusingqongileyo, kuyenze ibe lukhetho olukhethwayo kushishino lokwakha.
