I-Putty powder sisixhobo sokwakha esithandwayo esisetyenziselwa ukuvala izithuba, iintanda kunye nemingxuma kumphezulu phambi kokupeyinta okanye ukufaka iithayile. Izithako zayo zibandakanya i-gypsum powder, i-talcum powder, amanzi kunye nezinye izinto. Nangona kunjalo, iiputty eziqulunqiweyo zanamhlanje zikwanazo isithako esongezelelweyo, i-hydroxypropyl methylcellulose (HPMC). Eli nqaku liza kuxubusha ukuba kutheni songeza i-HPMC kwi-putty powder kunye neenzuzo ezizisayo.
I-Hydroxypropyl methylcellulose i-polymer e-soluble yamanzi ephuma kwi-cellulose, inxalenye ephambili yeendonga zeeseli zesityalo. Isetyenziswa kakhulu kumashishini ahlukeneyo afana nokwakha, amayeza, amalaphu kunye nokutya. Ekwakhiweni, isetyenziswe njengesithako kwi-mortars, i-grouts, iipende kunye ne-putty.
Ukongeza i-HPMC kwi-putty powder inezi zinzuzo zilandelayo:
1. Ukwandisa ukugcinwa kwamanzi
I-HPMC yipolymer eyihydrophilic efunxa kwaye igcine iimolekyuli zamanzi. Ukongeza i-HPMC kwi-putty powder inokuphucula ukusebenza kwayo kokugcinwa kwamanzi. Ngethuba lokwakha, i-putty powder exutywe ne-HPMC ayiyi kumisa ngokukhawuleza, inika abasebenzi ixesha elaneleyo lokusingatha izinto eziphathekayo kunye nokugcwalisa ngokufanelekileyo izikhewu ngaphandle kokubangela ukuba izinto zidibanise okanye zinciphise. Kunye nokugcinwa kwamanzi okwandisiweyo, i-putty powders nayo ibophelela kakuhle kumphezulu, inciphisa amathuba okuqhekeka okanye ukuxobuka.
2. Ukuphucula ukusebenza
Umgubo weputty uxutywa ne-HPMC ukwenza ukuncamathela okufana nokungaguquguquki, ukwenza kube lula ukugalela kunye nokusasazeka kuyo yonke imiphezulu. I-HPMC inika i-putty powders ukuthungwa okugudileyo, inika ukugqitywa okungcono xa ipeyinta okanye ukupeyinta. Kwakhona kunika i-putty ixabiso lesivuno esiphezulu, ukukwazi ukuxhathisa i-deformation phantsi koxinzelelo. Oku kuthetha ukuba umgubo weputty oxutywe ne-HPMC unokubunjwa ngokulula kwaye ulungele ukuhambelana nemiphezulu eyahlukeneyo.
3. Nciphisa i-shrinkage kunye nokuqhekeka
Njengoko kuchaziwe ngaphambili, i-HPMC inokuphucula ukugcinwa kwamanzi kwi-putty powder. Ngenxa yoko, i-putty powder ayinakwenzeka ukuba yome ngokukhawuleza xa isetyenziswe kumphezulu, ibangela i-shrinkage kunye nokuqhekeka. I-HPMC ikwanceda ekunciphiseni ukushwabana nokuqhekeka ngenxa yokuba inyusa amandla ebhondi yomgubo weputty, yenza izinto ezizinzileyo kwaye zingabinangxaki yokuqhekeka.
4. Ukuchasana ngcono kumanzi kunye nokutshintsha kweqondo lokushisa
I-putty powder exutywe ne-HPMC inokuchasana okungcono kwamanzi kunye nokutshintsha kweqondo lokushisa kune-putty powder ngaphandle kwe-HPMC. I-HPMC yipolymer eyi-hydrophilic ekhusela i-putty powders kubushushu kunye notshintsho lokufuma. Oku kuthetha ukuba i-putty powder exutywe ne-HPMC yomelele kwaye inokumelana nokuvezwa kwiimeko zemozulu ezahlukeneyo.
5. Ubomi obude beshelufu
Ukongeza i-HPMC kwi-putty powder inokwandisa ubomi bayo beshelufu. I-HPMC ikhusela i-putty powders ukuba yome kwaye iqine ngexesha lokugcinwa. Oku kuthetha ukuba i-putty powder exutywe ne-HPMC inokugcinwa ixesha elide ngaphandle kokulahlekelwa ngumgangatho okanye ingasebenzi.
Ukushwankathela, ukongeza i-HPMC kwi-putty powder kuneenzuzo ezininzi. Yandisa ukugcinwa kwamanzi, iphucula inkqubo, inciphisa ukucutheka kunye nokuqhekeka, inika ukuchasana okungcono kwamanzi kunye nokutshintsha kweqondo lokushisa, kwaye yandisa ubomi beshelufu. Zonke ezi zibonelelo ziqinisekisa ukuba i-putty powder exutywe ne-HPMC iya kunika ukugqitywa okungcono kwaye ibe yinto ehlala ixesha elide. Ngaloo ndlela, iyinxalenye ebalulekileyo efak’ isandla kwimpumelelo yawo nawuphi na umsebenzi wokwakha.
Ngokubanzi, ukusetyenziswa kwe-HPMC kwi-putty powders luphuhliso oluhle kwishishini lokwakha. Inika uncedo oluninzi olunceda ukwenza umsebenzi womntu wonke ube lula, usebenze ngakumbi kwaye usebenze kakuhle. Ukusetyenziswa kwayo okuqhubekayo kunokukhokelela ekuphuculeni ngakumbi umgangatho wezinto zokwakha kunye nezenzo zokwakha.
