Ukusetyenziswa koshishino oluthile lwe-cellulose ethers kwiputty powder

I-Putty powder sisixhobo sokwakha esisetyenziswa ngokuqhelekileyo, esisetyenziswa kakhulu ekulinganisweni kodonga, ukuzalisa iintanda kunye nokubonelela ngomphezulu ogudileyo wokupeyinta nokuhombisa okulandelayo. I-cellulose ether yenye yezongezo ezibalulekileyo kwi-putty powder, enokuphucula kakhulu umsebenzi wokwakha kunye nomgangatho we-putty powder. Eli nqaku liza kwazisa ngokuthe ngqo ukusetyenziswa kwe-cellulose ethers kwi-putty powder kunye nokubaluleka kwayo kwishishini lokwakha.

 

1. Iimpawu ezisisiseko kunye nemisebenzi ye-cellulose ethers

I-Cellulose ether luhlobo lwekhompawundi ye-polymer enyibilikayo emanzini efunyenwe ngokuguqulwa kweekhemikhali kusetyenziswa i-cellulose yendalo njengento ekrwada. Ulwakhiwo lwalo lwemolekyuli luqulethe inani elikhulu lamaqela e-hydrophilic (afana ne-hydroxyl, i-methoxy, njl.), enika i-cellulose ether ukunyibilika kakuhle kwamanzi kunye nokukwazi ukutyeba. Ekusetyenzisweni kwe-putty powder, indima ephambili ye-ether ye-cellulose ibonakala ngokukodwa kule miba ilandelayo:

 

Isiphumo sokutyeba

I-cellulose ether inokunyusa kakhulu i-viscosity ye-putty powder slurry, iyenze ibe ne-thixotropy elungileyo kunye nokuzinza, ngaloo ndlela iququzelele ukwakhiwa. Ukongeza, inokuphinda ilungelelanise iipropathi ze-rheological ze-slurry ukukhusela i-putty powder ukuba ihambe okanye ikhuphe eludongeni, iqinisekise inkqubela phambili yolwakhiwo.

 

Ukugcinwa kwamanzi

Ukugcinwa kwamanzi okuphezulu kwe-cellulose ether yenye yeempawu zayo ezibalulekileyo xa isetyenziswe kwi-putty powder. Ngethuba lenkqubo yokwakha, emva kokuba i-putty powder isetyenziswe eludongeni, ukukhuphuka kwamanzi kunokubangela ukuba i-putty powder yome kwaye i-peel. I-ether ye-cellulose inokulibazisa ngokufanelekileyo ukulahlekelwa kwamanzi, okubangela ukuba i-slurry ikhulule ngokuthe ngcembe amanzi ngexesha lenkqubo yokomisa, ngaloo ndlela iphucula ukunamathela kwe-putty, ukuphepha ukomisa kunye nokuqhekeka, kunye nokuqinisekisa ukugudisa kwendawo yodonga.

 

Ukuphucula ukusebenza

Ubukho be-cellulose ether buphucula kakhulu ukusebenza kokwakhiwa kwe-putty powder. Ngokomzekelo, inokuphucula ukuguquguquka kwe-putty, okwenza kube lula kubasebenzi bokwakha ukukrazula i-putty ngokulinganayo. Ukongeza, i-cellulose ether inokunciphisa isizukulwana samaqamza kwi-putty surface kwaye iphucule ukugudisa, ngaloo ndlela iphucula umphumo wokuhombisa.

 

Yandisa iiyure zokuvula

Ekwakhiweni, ixesha lokuvula i-putty powder, oko kukuthi, ixesha elivela kwisicelo sokumisa kunye nokuqina kwezinto eziphathekayo, ipharamitha ebalulekileyo eyenziwa ngabasebenzi bokwakha ingqalelo. I-ether ye-cellulose inokwandisa ixesha lokuvula i-putty, ukunciphisa amajoyina kunye nokungalingani ngexesha lokwakha, ngaloo ndlela iphucula i-aesthetics yonke eludongeni.

 

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

I-putty yodonga lwangaphakathi

Ekusetyenzisweni kwe-putty yodonga lwangaphakathi, i-ether ye-cellulose ayiphuculi nje kuphela ukusebenza, kodwa iyakwazi ukulungelelanisa ukumanzi kunye nokunamathela kwi-putty ukuqinisekisa ukugudiswa kunye nokunamathela komphezulu wodonga. Ukongezelela, ukusebenza okuphezulu kokugcinwa kwamanzi kwe-cellulose ether kunokuthintela i-putty ekuqhekekeni ngenxa yokunyuka kwamanzi ngokukhawuleza ngexesha lenkqubo yesicelo, kwaye ifanelekile kwiimfuno zokuzinza kwexesha elide kwiindawo ezomileyo zangaphakathi.

 

Iputty yodonga lwangaphandle

I-putty yodonga lwangaphandle kufuneka ibe nokuchasana okunamandla kwemozulu kunye nokumelana nokuqhekeka, kuba umphezulu wodonga lwangaphandle uya kuchaphazeleka yimozulu, ukungafani kobushushu kunye nezinye izinto. Ukusetyenziswa kwe-cellulose ether kwi-putty yangaphandle eludongeni kunokuphucula kakhulu ukugcinwa kwamanzi, ukuchasana nokuqhekeka kunye nokunamathela, okukuvumela ukuba ulungelelanise utshintsho kwimeko yangaphandle kunye nokwandisa ubomi bayo benkonzo. Ukongeza, i-ether ye-cellulose inokunceda i-putty iphucule ukuxhathisa kwe-UV, ukuxhathisa ukunyibilika komkhenkce kunye nezinye iipropathi, ukuze i-putty yodonga lwangaphandle ikwazi ukugcina iipropati zomzimba ezizinzileyo phantsi kweemeko zangaphandle.

 

iputty engenamanzi

I-putty engenamanzi ifanelekile kwiindawo eziphakamileyo zokufuma ezifana neendawo zokuhlambela kunye neekhikhini, kwaye ifuna ukukhuseleka kwamanzi okuphezulu kunye nokuchasana kwamanzi kwi-putty. I-ether ye-cellulose inokuphucula ukusebenza kwamanzi kwi-putty ngesiseko sokuqinisekisa ukunamathela kwayo okulungileyo kunye nokusebenza kakuhle. Ukongeza, ukutyeba kunye neziphumo zokugcina amanzi ze-cellulose ether zenza ukuba i-putty ingangeni manzi ukugcina uzinzo oluhle kwindawo enomswakama ophezulu kwaye igweme iingxaki ze-mildew kwiindonga.

 

I-putty ephezulu yokuhlobisa

I-putty yokuhlobisa i-high-end ineemfuno eziphezulu kakhulu zokulala kunye nobuhle, kwaye idla ngokusetyenziswa kwiindawo zokuhlala eziphezulu, iihotele kunye nezinye iindawo. I-ether ye-cellulose inokunceda ukucokisa amasuntswana e-putty, ukuphucula ukuguda kwendawo, ukuphucula ukuguquguquka kunye nokusebenza kwe-putty, ukunciphisa amaqamu kunye nemithungo, ukwenza umphumo wokuhombisa ugqibelele ngakumbi, kwaye uhlangabezane neemfuno zokuhombisa iindawo eziphezulu.

 

3. Ukukhethwa kobugcisa be-cellulose ether kwi-putty powder

Ngokweemfuno zesicelo kunye neemfuno ezahlukeneyo zokusebenza kweputty powder, ezi ether zeselulosi zilandelayo zihlala zisetyenziswa kushishino lokwakha:

 

IHydroxypropyl methylcellulose (HPMC)

I-HPMC sisongezo sokwakha esisetyenziswa ngokuqhelekileyo esinogcino lwamanzi olugqwesileyo kunye neziphumo ezityebileyo. Isetyenziswa ngokubanzi kwizinto zokwakha ezifana ne-putty yangaphakathi nangaphandle yodonga, i-adhesives ye-tile, kunye nodaka lokutyabeka. Inokuphucula ukuxhathisa kwe-sag kunye nokusebenza kwe-putty powder, kwaye ifaneleke ngokukodwa kwiimfuno ze-high-viscosity putty.

 

I-Hydroxyethylmethylcellulose (HEMC)

I-HEMC inomsebenzi ogqwesileyo wokugcinwa kwamanzi kunye nokuzinza, ngakumbi kwiindawo zokushisa eziphantsi, kwaye isenako ukugcina ukunyibilika okulungileyo, ngoko ifanelekile ukusetyenziswa kwi-putty yangaphandle eludongeni. Ukongeza, i-HEMC inefuthe elihle kakhulu ekuphuculeni ukusasazeka kunye nokufana kwe-putty powder, okwenza ukuba ubuso bube lula kwaye bube bushelelezi emva kokugubungela.

 

Carboxymethyl cellulose (CMC)

I-CMC sisitshizi esinyibilikayo samanzi. Nangona inokugcinwa kwamanzi aphantsi kunye neempawu ezichasene ne-sag, ixabiso layo liphantsi. Ihlala isetyenziselwa i-putty powder engadingi ukugcinwa kwamanzi aphezulu kwaye ifanelekile kwizicelo ze-putty zangaphakathi zangaphakathi.

 

4. Amathemba kunye neendlela ze-cellulose ethers kwi-putty powder industry

Ngophuhliso oluqhubekayo lweshishini lokwakha, iimfuno zabantu kumgangatho, ukukhuselwa kwendalo kunye ne-aesthetics yezinto zokuhombisa ziye zanda ngokuthe ngcembe, kwaye ithemba lesicelo se-cellulose ethers liye lakhula ngokubanzi. Kwixesha elizayo lophuhliso lweshishini le-putty powder, ukusetyenziswa kwe-cellulose ether kuya kugxininisa kule miba ilandelayo:

 

Uhlaza kunye nokusingqongileyo

Okwangoku, izinto zokwakha ezihambelana nokusingqongileyo zingumxholo oshushu kwishishini lokwakha. Njengesixhobo se-polymer esivela kwi-cellulose yendalo, i-cellulose ether ihambelana nombono wokukhusela okusingqongileyo okuluhlaza kwaye inokunciphisa ngokufanelekileyo ukungcoliseka kokuhlobisa. Kwixesha elizayo, ngaphezulu kwe-VOC ephantsi (i-volatile organic compounds) kunye nemveliso ephezulu ye-cellulose ether iya kuphuhliswa kwaye isetyenziswe.

 

Isebenza kakuhle kwaye ikrelekrele

Ukuphuculwa okuqhubekayo kwe-cellulose ether kwenza i-putty powder igcine ukusebenza okuzinzileyo kwiindawo ezinzima. Ngokomzekelo, ngokulungiswa kwe-molecular structure kunye nokongezwa kwezongezo, i-putty powder inokuguquguquka okunamandla kunye neempawu zokuziphilisa, okwenza izinto zokwakha zibe nengqondo kwaye zisebenze.

 

Ukuguquguquka

Ngelixa ukuphucula iimpawu ezisisiseko ze-putty powder, i-cellulose ethers nayo inokwenza i-putty powder ibe nemisebenzi eyongezelelweyo efana ne-antibacterial, anti-mildew, kunye ne-anti-UV ukuhlangabezana neemfuno zeemeko zesicelo esikhethekileyo.

 

Ukusetyenziswa kwe-cellulose ether kwi-putty powder akugcini nje ukulungelelanisa ukusebenza kokwakhiwa kunye nokuqina kwe-putty powder, kodwa kuphucula kakhulu umphumo wokuhlobisa udonga, ukuhlangabezana neemfuno zezakhiwo zanamhlanje zodonga oluthambileyo, ukuguda kunye nokuqina. . Ngophuhliso oluqhubekayo lweshishini lokwakha, ukusetyenziswa kwe-cellulose ethers kwi-putty powder kuya kuba kuninzi ngakumbi, ukutyhala izinto zokuhlobisa izakhiwo ngokubhekiselele ekusebenzeni okuphezulu kunye nokukhuselwa kwendalo.
