Izicelo ezithile zoshishino ze-cellulose ethers kwi-putty powder

I-Putty powder sisixhobo sokwakha esisetyenziswa kakhulu, esisetyenziselwa ikakhulu ukulinganisa udonga, ukugcwalisa iintanda kunye nokubonelela ngomphezulu ogudileyo wokupeyinta nokuhombisa okulandelayo. I-Cellulose ether yenye yezona zinto zibalulekileyo kwi-putty powder, ezinokuphucula kakhulu ukusebenza kolwakhiwo kunye nomgangatho we-putty powder. Eli nqaku liza kwazisa ngokweenkcukacha ukusetyenziswa kwe-cellulose ethers kwi-putty powder kunye nokubaluleka kwayo kushishino lokwakha.

1. Iipropati ezisisiseko kunye nemisebenzi ye-cellulose ethers

I-Cellulose ether luhlobo lwe-polymer compound enyibilikayo emanzini efunyenwe ngokuguqulwa kweekhemikhali kusetyenziswa i-cellulose yendalo njengezinto eziluhlaza. Ulwakhiwo lwayo lwe-molecular luqulathe inani elikhulu lamaqela e-hydrophilic (afana ne-hydroxyl, i-methoxy, njl.njl.), enika i-cellulose ether ukunyibilika kakuhle kwamanzi kunye nokukwazi ukutyeba. Ekusetyenzisweni kwe-putty powder, indima ephambili ye-cellulose ether ibonakaliswa kakhulu kwezi zinto zilandelayo:

Isiphumo sokuqina

I-Cellulose ether inokunyusa kakhulu i-viscosity ye-putty powder slurry, iyenze ibe ne-thixotropy elungileyo kunye nozinzo, ngaloo ndlela iququzelela ukwakhiwa. Ukongeza, inokulungisa iipropati ze-rheological ze-slurry ukuthintela i-putty powder ukuba ingaphumi okanye ityibilike eludongeni, iqinisekise inkqubela phambili egudileyo yokwakhiwa.

Ukugcinwa kwamanzi

Ukugcinwa kwamanzi amaninzi kwe-cellulose ether yenye yeempawu zayo ezibalulekileyo xa isetyenziswa kwi-putty powder. Ngexesha lenkqubo yokwakha, emva kokuba i-putty powder isetyenzisiwe eludongeni, ukufuma kwamanzi kunokubangela ukuba i-putty powder yome kwaye ixobuke. I-Cellulose ether inokulibazisa ukulahleka kwamanzi ngempumelelo, okubangela ukuba i-slurry ikhuphe amanzi kancinci ngexesha lenkqubo yokomisa, ngaloo ndlela iphucula ukunamathela kwe-putty, iphephe ukoma nokuqhekeka, kwaye iqinisekise ukuba umphezulu wodonga uthambile.

Phucula ukusebenza kakuhle

Ukubakho kwe-cellulose ether kuphucula kakhulu ukusebenza kolwakhiwo lwe-putty powder. Umzekelo, kunokuphucula ukuguquguquka kwe-putty, okwenza kube lula kubasebenzi bokwakha ukukrwela i-putty ngokulinganayo. Ukongeza, i-cellulose ether inokunciphisa ukuveliswa kwamaqamza kumphezulu we-putty kwaye iphucule ukuguda, ngaloo ndlela iphucula isiphumo sokuhombisa.

Yandisa iiyure zokuvula

Ekwakhiweni, ixesha lokuvulwa kwe-putty powder, oko kukuthi, ixesha ukusuka ekusetyenzisweni ukuya ekomeni nasekuqineni kwezinto, lipharamitha ebalulekileyo enikwa ingqalelo ngabasebenzi bokwakha. I-cellulose ether inokwandisa ixesha lokuvulwa kwe-putty, inciphise amalungu kunye nokungalingani ngexesha lokwakhiwa, ngaloo ndlela iphucula ubuhle bodonga ngokubanzi.

2. Ukusetyenziswa kwe-cellulose ether kwiimeko ezahlukeneyo ze-putty powder

I-putty yodonga yangaphakathi

Xa kusetyenziswa i-interior wall putty, i-cellulose ether ayiphuculi nje kuphela ukusebenza kakuhle, kodwa ikwalungisa ukutyibilika kunye nokunamathela kwe-putty ukuqinisekisa ukuba umphezulu wodonga uthambile kwaye unamathela. Ukongeza, ukusebenza okuphezulu kokugcinwa kwamanzi kwe-cellulose ether kunokuthintela i-putty ukuba ingaqhekeki ngenxa yokuphuma kwamanzi ngokukhawuleza ngexesha lenkqubo yokufaka, kwaye ifanelekile kwiimfuno zozinzo lwexesha elide kwiindawo ezomileyo zangaphakathi.

I-putty yodonga yangaphandle

I-wall putty yangaphandle kufuneka ibe nokumelana okunamandla kwemozulu kunye nokuxhathisa ukuqhekeka, kuba umphezulu wodonga lwangaphandle uya kuchaphazeleka yimozulu, umahluko kumaqondo obushushu kunye nezinye izinto. Ukusetyenziswa kwe-cellulose ether kwi-wall putty yangaphandle kunokuphucula kakhulu ukugcinwa kwamanzi, ukumelana nokuqhekeka kunye nokunamathela, okuvumela ukuba ivumelane notshintsho kwimeko-bume yangaphandle kwaye yandise ubomi bayo benkonzo. Ukongeza, i-cellulose ether inokunceda i-putty ukuba iphucule ukumelana kwayo ne-UV, ukumelana nokuqandisa kunye nezinye iimpawu, ukuze i-wall putty yangaphandle ikwazi ukugcina iimpawu zomzimba ezizinzileyo phantsi kweemeko zangaphandle.

i-putty engangeni manzi

I-putty engangeni manzi ifanelekile kwiindawo ezinomswakama ophezulu ezifana nezindlu zangasese kunye neekhitshi, kwaye ifuna ukungangeni manzi okuphezulu kunye nokumelana namanzi kwe-putty. I-Cellulose ether inokuphucula ukusebenza kokungena manzi kwe-putty ngokusekelwe ekuqinisekiseni ukunamathela kwayo kakuhle kunye nokusebenza kwayo. Ukongeza, iziphumo zokutyeba kunye nokugcina amanzi ze-cellulose ether zenza i-putty engangeni manzi ihlale izinzile kwiindawo ezinomswakama ophezulu kwaye iphephe iingxaki ze-mildew eludongeni.

I-putty yokuhombisa ephezulu

I-putty yokuhombisa ephezulu ineemfuno eziphezulu kakhulu zokuthambisa nokucoleka, kwaye idla ngokusetyenziswa kwiindawo zokuhlala eziphezulu, iihotele nakwezinye iindawo. I-Cellulose ether inokunceda ekucoceni amasuntswana e-putty, iphucule ukuguda komphezulu, iphucule ukuguquguquka nokusebenza kakuhle kwe-putty, inciphise amaqamza kunye nemithungo, yenze isiphumo sokuhombisa sigqibelele ngakumbi, kwaye ihlangabezane neemfuno zokuhombisa zeendawo eziphezulu.
