Ukusetshenziswa okukhethekile kwemboni ye-cellulose ethers ye-putty powder

I-Putty powder iyimpahla yokwakha evame ukusetshenziswa, ikakhulukazi esetshenziselwa ukulinganisa udonga, ukugcwalisa imifantu kanye nokunikeza indawo ebushelelezi yokudweba nokuhlobisa okulandelayo. I-Cellulose ether ingenye yezithako ezibalulekile ku-putty powder, ezingathuthukisa kakhulu ukusebenza kokwakhiwa kanye nekhwalithi ye-putty powder. Lesi sihloko sizokwethula ngokuningiliziwe ukusetshenziswa okuqondile kwe-cellulose ethers ku-putty powder kanye nokubaluleka kwayo embonini yezokwakha.

1. Izakhiwo eziyisisekelo nemisebenzi yama-cellulose ethers

I-Cellulose ether iwuhlobo lwenhlanganisela ye-polymer encibilika emanzini etholwe ngokuguqulwa kwamakhemikhali kusetshenziswa i-cellulose yemvelo njengempahla eluhlaza. Ukwakheka kwayo kwamangqamuzana kuqukethe inani elikhulu lamaqembu e-hydrophilic (njenge-hydroxyl, i-methoxy, njll.), enikeza i-cellulose ether ukuncibilika okuhle kwamanzi kanye nekhono lokujiya. Ekusetshenzisweni kwe-putty powder, indima ebalulekile ye-cellulose ether ibonakala ngokuyinhloko kulezi zici ezilandelayo:

Ukuqina komphumela

I-cellulose ether ingakhuphula kakhulu i-viscosity ye-putty powder slurry, iyenze ibe ne-thixotropy enhle nokuzinza, ngaleyo ndlela kube lula ukwakhiwa. Ngaphezu kwalokho, ingakwazi futhi ukulungisa izakhiwo ze-rheological ze-slurry ukuvimbela i-putty powder ukuthi ingagelezi noma isuke odongeni, iqinisekise ukuqhubeka kahle kokwakhiwa.

Ukugcinwa kwamanzi

Ukugcinwa kwamanzi okuphezulu kwe-cellulose ether kungenye yezici zayo ezibalulekile uma kusetshenziswe ku-putty powder. Ngesikhathi senqubo yokwakha, ngemuva kokuthi i-putty powder isetshenziswe odongeni, ukuhwamuka kwamanzi kungabangela ukuthi i-putty powder yome futhi icwecwe. I-Cellulose ether ingabambezela ngempumelelo ukulahleka kwamanzi, okubangela ukuthi udaka ludedele amanzi kancane kancane phakathi nenqubo yokomisa, ngaleyo ndlela kuthuthukiswe ukunamathela kwe-putty, kugweme ukomiswa nokuqhekeka, nokuqinisekisa ukushelela kodonga.

Thuthukisa ukusebenza

Ukuba khona kwe-cellulose ether kuthuthukisa kakhulu ukusebenza kokwakhiwa kwe-putty powder. Isibonelo, ingathuthukisa ukuguquguquka kwe-putty, okwenza kube lula kubasebenzi bokwakha ukukhuhla i-putty ngokulinganayo. Ngaphezu kwalokho, i-cellulose ether nayo inganciphisa ukukhiqizwa kwamabhamuza endaweni ye-putty futhi ithuthukise ukushelela, ngaleyo ndlela ithuthukise umphumela wokuhlobisa.

Nweba amahora okuvula

Ekwakhiweni, isikhathi sokuvula se-putty powder, okungukuthi, isikhathi kusukela ekusetshenzisweni kuya ekomisweni nasekuqinisweni kwezinto ezibonakalayo, ipharamitha ebalulekile abasebenzi bezokwakha abayinaka. I-cellulose ether inganweba isikhathi sokuvula se-putty, inciphise amalunga nokungalingani ngesikhathi sokwakhiwa, ngaleyo ndlela ithuthukise ubuhle obuphelele bodonga.

2. Ukusetshenziswa kwe-cellulose ether ezimweni ezahlukene ze-putty powder

I-wall putty yangaphakathi

Ekusetshenzisweni kwe-putty yangaphakathi yodonga, i-cellulose ether ayithuthukisi kuphela ukusebenza kahle, kodwa futhi ingalungisa uketshezi nokunamathela kwe-putty ukuze kuqinisekiswe ukushelela nokunamathela kwendawo yodonga. Ukwengeza, ukusebenza okuphezulu kokugcinwa kwamanzi kwe-cellulose ether kungavimbela i-putty ekuqhekekeni ngenxa yokuhwamuka kwamanzi ngokushesha phakathi nenqubo yokufaka isicelo, futhi ifanelekela izidingo zokuzinza kwesikhathi eside ezindaweni ezomile zasendlini.

I-wall putty yangaphandle

I-putty yangaphandle yodonga idinga ukumelana nesimo sezulu esinamandla nokumelana nokuqhekeka, ngoba ubuso bodonga lwangaphandle buzothinteka isimo sezulu, umehluko wokushisa nezinye izici. Ukusetshenziswa kwe-cellulose ether ku-putty yangaphandle yodonga kungathuthukisa kakhulu ukugcinwa kwamanzi kwawo, ukumelana nokuqhekeka nokunamathela, okuwuvumela ukuba uvumelane nezinguquko endaweni yangaphandle futhi andise impilo yayo yesevisi. Ngaphezu kwalokho, i-cellulose ether ingasiza futhi i-putty ukuthi ithuthukise ukumelana kwayo ne-UV, ukumelana nokuncibilika kweqhwa nezinye izakhiwo, ukuze i-putty yangaphandle yodonga isengakwazi ukugcina izakhiwo ezinzile ngaphansi kwezimo zangaphandle.

i-putty engangeni manzi

I-putty engangeni manzi ifaneleka ezindaweni ezinomswakama ophezulu njengezindlu zangasese namakhishi, futhi idinga ukungangeni kwamanzi okuphezulu nokumelana namanzi kwe-putty. I-cellulose ether ingathuthukisa ukusebenza okungangeni kwamanzi kwe-putty ngesisekelo sokuqinisekisa ukunamathela kwayo okuhle nokusebenza kwayo. Ukwengeza, imiphumela yokuqina nokugcina amanzi ye-cellulose ether yenza i-putty engangeni manzi ukuze igcine ukuzinza okuhle ezindaweni ezinomswakama ophezulu futhi igweme izinkinga zokukhunta ezindongeni.

I-putty yokuhlobisa ephezulu

I-putty yokuhlobisa esezingeni eliphezulu inezidingo eziphakeme kakhulu zokulala nokucoleka, futhi ngokuvamile isetshenziswa ezindaweni zokuhlala eziphezulu, amahhotela nezinye izindawo. I-Cellulose ether ingasiza ekucwengeni izinhlayiya ze-putty, ithuthukise ukushelela kwendawo, ithuthukise ukuguquguquka nokusebenza kwe-putty, inciphise amabhamuza nemithungo, yenze umphumela wokuhlobisa ulunge kakhulu, futhi ihlangabezane nezidingo zokuhlobisa zezindawo eziphezulu.

3. Ukukhethwa kwezobuchwepheshe kwe-cellulose ether ku-putty powder

Ngokwezidingo zohlelo lokusebenza kanye nezidingo ezihlukile zokusebenza kwe-putty powder, ama-cellulose ether alandelayo avame ukusetshenziswa embonini yezokwakha:

I-Hydroxypropyl methylcellulose (HPMC)

I-HPMC iyisengezo sokwakha esisetshenziswa kakhulu esinokugcinwa kwamanzi okuhle kakhulu kanye nemiphumela yokujiya. Isetshenziswa kakhulu ezintweni zokwakha ezifana ne-wall putty yangaphakathi nangaphandle, izinamatheliso zamathayela, nezinsimbi zokukhonkoloza. Ingathuthukisa ukumelana ne-sag nokusebenza kwe-putty powder, futhi ifaneleka ngokukhethekile izidingo ze-high-viscosity putty.

I-Hydroxyethylmethylcellulose (HEMC)

I-HEMC inokusebenza okuhle kakhulu kokugcinwa kwamanzi nokuzinza, ikakhulukazi ezindaweni zokushisa eziphansi, futhi isengakwazi ukugcina ukuncibilika okuhle, ngakho ifanele ukusetshenziswa ku-putty yangaphandle yodonga. Ngaphezu kwalokho, i-HEMC inomphumela omuhle kakhulu ekuthuthukiseni ukuhlakazeka nokufana kwe-putty powder, okwenza ubuso bube bushelelezi futhi bushelelezi ngemva kokumboza.

I-Carboxymethyl cellulose (CMC)

I-CMC iwugqinsi oncibilikayo emanzini. Nakuba inezindawo eziphansi zokugcina amanzi kanye nezindawo zokulwa ne-sag, izindleko zayo ziphansi. Ivame ukusetshenziswa ku-putty powder engadingi ukugcinwa kwamanzi aphezulu futhi ifanele izicelo ezijwayelekile zangaphakathi zodonga lwe-putty.

4. Amathemba kanye nezitayela ze-cellulose ethers embonini ye-putty powder

Ngokuthuthuka okuqhubekayo kwemboni yezokwakha, izidingo zabantu zekhwalithi, ukuvikelwa kwemvelo kanye nobuhle bezinto zokuhlobisa ziye zanda kancane kancane, futhi amathemba okusetshenziswa kwe-cellulose ethers ayanda kakhulu. Esikhathini esizayo sokuthuthukiswa komkhakha we-putty powder, ukusetshenziswa kwe-cellulose ether kuzogxila kulezi zici ezilandelayo:

Okuluhlaza futhi kuhambisana nemvelo

Njengamanje, izinto zokwakha ezinobungani bemvelo ziyisihloko esishisayo embonini yezokwakha. Njengento ye-polymer etholakala ku-cellulose yemvelo, i-cellulose ether ihambisana nomqondo wokuvikelwa kwemvelo okuluhlaza futhi inganciphisa ngempumelelo ukungcoliswa komhlobiso. Ngokuzayo, kuzothuthukiswa futhi kusetshenziswe imikhiqizo ye-cellulose ether ye-cellulose ephezulu (i-volatile organic compounds).

Isebenza kahle futhi ihlakaniphile

Ukuthuthukiswa okuqhubekayo kwe-cellulose ether kwenza i-putty powder igcine ukusebenza okuzinzile ezindaweni eziyinkimbinkimbi. Isibonelo, ngokusebenzisa ukulungiswa kwesakhiwo samangqamuzana kanye nokwengezwa kwezithasiselo, i-putty powder inokuguquguquka okunamandla kanye nezindawo zokuziphilisa, okwenza izinto zokwakha zihlakaniphe futhi ziphumelele.

Ukuguquguquka

Nakuba kuthuthukisa izici eziyisisekelo ze-putty powder, i-cellulose ethers ingenza futhi i-putty powder ibe nemisebenzi eyengeziwe efana ne-antibacterial, anti-mildew, ne-anti-UV ukuze kuhlangatshezwane nezidingo zezimo zohlelo lokusebenza olukhethekile.

Ukusetshenziswa kwe-cellulose ether ku-putty powder akugcini nje ukuthuthukisa ukusebenza kokwakhiwa nokuqina kwe-putty powder, kodwa futhi kuthuthukisa kakhulu umphumela womhlobiso odongeni, ukuhlangabezana nezidingo zezakhiwo zesimanje zodonga oluthambile, ukushelela nokuqina. . Ngokuthuthuka okuqhubekayo kwemboni yezokwakha, ukusetshenziswa kwe-cellulose ethers ku-putty powder kuzokwanda kakhulu, kuphushe izinto zokuhlobisa izakhiwo ekusebenzeni okuphezulu nokuvikelwa kwemvelo.
