I-putty kunye ne-plaster zizinto ezidumileyo ezisetyenziswa kakhulu kushishino lokwakha. Zibalulekile ekulungiseleleni iindonga kunye neesilingi zokupeyinta, ukugquma imifantu, ukulungisa iindawo ezonakeleyo, kunye nokudala iindawo ezigudileyo nezilinganayo. Zenziwe ngezithako ezahlukeneyo kuquka isamente, isanti, ilayimu kunye nezinye izongezo ukubonelela ngokusebenza okufunekayo kunye neempawu. I-Methylhydroxyethylcellulose (MHEC) yenye yezongezo eziphambili ezisetyenziswa ekuveliseni i-putty kunye ne-plaster powder. Isetyenziselwa ukuphucula iipropati zee-powders, ukuphucula iipropati zazo zokusebenza kunye nokwenza ngcono ukusetyenziswa kwazo.
Iingenelo zokusebenzisa i-MHEC ukuvelisa i-putty kunye ne-gypsum powder
I-MHEC ivela kwi-cellulose kwaye iveliswa ngenkqubo yokuguqula iikhemikhali. Yikhompawundi enyibilikayo emanzini esetyenziswa kakhulu njengesithambisi, isizinzisi kunye ne-emulsifier kwishishini lokwakha. Xa yongezwa kwi-putty kunye ne-gypsum powders, i-MHEC igquma amaqhekeza, inika umaleko okhuselayo othintela ukuba angadibani kwaye ahlale. Oku kuvelisa umxube olinganayo nohambelanayo olula ukusebenza ngawo kwaye ubonelela ngokugqitywa okungcono.
Enye yezona nzuzo ziphambili zokusebenzisa i-MHEC kwii-putty kunye nee-plaster kukuba iphucula iipropati zayo zokugcina amanzi. I-MHEC ifunxa kwaye igcina umswakama, iqinisekisa ukuba umxube uhlala usetyenziswa kwaye awomi ngokukhawuleza. Oku kubaluleke kakhulu kwiindawo ezishushu nezomileyo apho umxube ukhawuleza ungasetyenziswa, nto leyo ebangela ukuba ugqitywe kakubi.
I-MHEC ikwaphucula ukusebenza kakuhle kunye nexesha lokusebenza kwee-putty kunye nee-plaster. I-MHEC yenza ukuxuba nokusebenzisa umxube kube lula ngokugcina umswakama kunye nokuthintela umxube ukuba wome. Ukongeza, ubume obuthambileyo be-MHEC, obufana nebhotolo buvumela i-putty kunye ne-stucco ukuba zisasazeke ngokulinganayo phezu komphezulu ngaphandle kokushiya amaqhuma okanye amaqhuma, okuqinisekisa ukugqitywa okugqibeleleyo nokuhle.
Ukongeza ekuphuculeni ubume kunye nokusebenza kakuhle kwee-putty kunye nee-plaster, i-MHEC inokuphucula iimpawu zazo zokubopha. Ngokwenza umaleko okhuselayo ojikeleze amasuntswana, i-MHEC iqinisekisa ukuba anamathelana ngcono kumphezulu abawunyangayo. Oku kubangela umphezulu oqinileyo, ohlala ixesha elide ongenakufane uqhekeke, uqhekeke okanye uxobuke ngokuhamba kwexesha.
Enye inzuzo ebalulekileyo yokusebenzisa i-MHEC kwi-putty nakwi-plaster kukuba inyusa ukumelana kwazo nomoya nokufuma. Oku kuthetha ukuba xa i-putty okanye i-stucco ifakiwe, iya kuxhathisa umonakalo ovela emoyeni nokufuma, iqinisekise ukuba umphezulu uhlala uqinile kwaye umhle ixesha elide.
Ukuphucula ukusebenza kwePutty kunye neGypsum kusetyenziswa iMHEC
Ukuze kuphuculwe ukusebenza kwe-putty kunye ne-plaster powder, kubalulekile ukuqinisekisa ukuba i-MHEC isetyenziswa ngomlinganiselo ochanekileyo. Oku kuthetha ukuba ukusebenzisa ubungakanani obuchanekileyo be-MHEC kunokufezekisa ukusebenza okufunekayo kunye neempawu ze-putty okanye i-stucco eveliswayo.
Izinto ezichaphazela ukusebenza kwe-putty kunye ne-gypsum powder maziqwalaselwe. Umzekelo, kwiindawo ezishushu nezomileyo, kusenokufuneka kongezwe i-MHEC engaphezulu ukuqinisekisa ukuba umxube uhlala uphilile kwaye uhambelana.
Kubalulekile ukuqinisekisa ukuba i-putty okanye i-stucco isetyenziswa ngokuchanekileyo ukuze isebenze kakuhle. Oku kuthetha ukulandela imiyalelo yomenzi ngononophelo kwaye uqinisekise ukuba umxube uxutywe kakuhle ngaphambi kokuba usetyenziswe. Ukongeza, izixhobo ezikhethekileyo zinokufuneka ukuqinisekisa ukuba i-putty okanye i-stucco isetyenziswa ngokulinganayo nangokungaguquguqukiyo kumphezulu ophathwayo.
I-MHEC sisithako esibalulekileyo esisetyenziswa ekuvelisweni kwe-putty kunye ne-plaster powder. Iphucula iipropati kunye neempawu zezi zinto, iphucula ukusebenziseka kwazo, ukugcinwa kwamanzi, ukunamathela kunye nokumelana nomoya kunye nokufuma. Oku kubangela ukuba zigqibelele ngokuthe ngcembe, ziqine kwaye zinomtsalane kwaye azinakuqhekeka, ziqhekeke okanye ziqhekeke ngokuhamba kwexesha. Ukuze kuphuculwe ukusebenza kwe-putty kunye ne-gypsum powder, kubalulekile ukuqinisekisa ukuba kusetyenziswa idosi echanekileyo ye-MHEC, kuthathelwa ingqalelo izinto ezingqongileyo ezinokuchaphazela ukusebenza kwazo. Ukongeza, kubalulekile ukusebenzisa i-putty okanye i-stucco ngokuchanekileyo ukuze kuphuculwe ukusebenza kwayo kwaye kufezekiswe iziphumo ezifunwayo.
I-HEMC isetyenziswa kwimixube yesamente ukuphucula iipropati zayo. I-Hydroxyethyl methylcellulose (HEMC) yikhemikhali esetyenziswa kakhulu kushishino lokwakha. Yikhonkco phakathi kokusebenza kakuhle, ukugcinwa kwamanzi, i-thixotropy, njl. Kule mihla, uhlobo olutsha lwe-cellulose ether lufumana ingqwalasela engakumbi. Okuye kwatsala ingqwalasela engakumbi yi-hydroxyethyl methylcellulose (MHEC).
Enye yezona zinto zibalulekileyo ezimisela umgangatho weemveliso zesamente kukusebenza kakuhle komxube. Yiyo loo nto kulula ukuyixuba, ukuyila kunye nokuyibeka endaweni yayo. Ukuze kufezekiswe oku, umxube wesamente kufuneka ube manzi ngokwaneleyo ukuze ugalele kwaye uphume lula, kodwa kufuneka ube krakra ngokwaneleyo ukuze ubambe imo yawo. I-MHEC inokufezekisa olu phawu ngokunyusa i-viscosity yesamente, ngaloo ndlela iphucule ukusebenza kwayo.
I-MHEC ikwanokukhawulezisa ukufuma kwesamente kwaye iphucule amandla ayo. Amandla okugqibela esamente axhomekeke kubungakanani bamanzi asetyenziswayo ukuyixuba. Amanzi amaninzi aya kunciphisa amandla esamente, ngelixa amanzi amancinci kakhulu enza kube nzima kakhulu ukusebenza ngayo. I-MHEC inceda ukugcina amanzi athile, ngaloo ndlela iqinisekisa ukufuma kwesamente ngokufanelekileyo kwaye ikhuthaza ukwakheka kwamaqhina aqinileyo phakathi kwamasuntswana esamente.
I-MHEC inceda ekunciphiseni inani leemifantu zesamente. Njengoko isamente iphela, umxube uyancipha, nto leyo enokubangela ukuba kubekho imifantu ukuba ukuncipha akulawuleki. I-MHEC ithintela oku kuncipha ngokugcina amanzi afanelekileyo kumxube, ngaloo ndlela ithintela isamente ukuba ingaqhekeki.
I-MHEC ikwasebenza njengefilimu ekhuselayo kumphezulu wesamente, ithintela amanzi ukuba angaphumi kumphezulu. Le filimu ikwanceda ukugcina umxholo wokufuma wokuqala wesamente, inciphisa ngakumbi amathuba okuqhekeka.
I-MHEC ikwalungele okusingqongileyo. Okokuqala, iyabola, oko kuthetha ukuba ayihlali kwindawo okuyo ixesha elide. Okwesibini, inokunceda ukunciphisa ubungakanani besamente efunekayo kwiprojekthi zokwakha. Oku kungenxa yokuba i-MHEC yonyusa ukusebenza kakuhle kunye nokuqina kwesamente, inciphisa isidingo samanzi ongezelelweyo anciphisa nje umxube wesamente.
Ukusetyenziswa kwe-MHEC kwisamente kunika iingenelo ezininzi kwaye kunokwenza igalelo elikhulu kwishishini lokwakha. Kuyonyusa ukusebenza kakuhle komxube wesamente, kunciphisa inani leentanda ezenziweyo ngexesha lokunyibilika, kukhuthaza ukufuma kwesamente kunye namandla, kwaye kusebenza njengefilimu ekhuselayo kumphezulu wesamente. Ukongeza, i-MHEC ilungile kwindalo esingqongileyo. Ke ngoko, i-MHEC yimveliso exabisekileyo kwishishini lokwakha njengoko iphucula umgangatho wesamente kwaye inika iingenelo kubasebenzi nakwindalo esingqongileyo.
