Ukusetyenziswa kwe-ether ye-cellulose kwi-putty eludongeni kunye ne-putty

1. Isishwankathelo se-cellulose ether

I-cellulose ether yiklasi ye-polymer e-soluble yamanzi okanye i-dispersible water compounds eyenziwe ngokuguqulwa kweekhemikhali ngokusekelwe kwi-cellulose yendalo. I-cellulose ethers eqhelekileyo iquka i-hydroxypropyl methylcellulose (HPMC), i-hydroxyethyl cellulose (HEC), i-hydroxypropyl cellulose (HPC), njl. izixhobo.

2. Indima ye-cellulose ether kwi-putty

Ukuphucula ukusebenza kokwakhiwa kwe-putty

I-ether ye-cellulose iphucula iimpawu ze-rheological ze-putty, ukwenzela ukuba ukusebenza kunye nokulinganisa iimpawu ze-putty zinokuphuculwa, okwenza kube lula ukuzisebenzisa kunye nenqanaba. Ngokukodwa kulwakhiwo olukhulu, ipropathi etyebileyo ye-cellulose ether inokwenza i-putty ibambelele ngakumbi eludongeni, inciphise ukugoba, kwaye iqinisekise ukuzinza komgangatho wokwakha.

Ukuphucula ukugcinwa kwamanzi

I-putty layer idinga ukugcina imeko ethile emanzi ngexesha lenkqubo yokwakha ukuqinisekisa ukufana kunye nokunamathela kwenkqubo yokumisa elandelayo. Iimolekyuli ze-ether ze-cellulose zinokufunxa isixa esikhulu samanzi kwaye zenze inethiwekhi ye-molecule yamanzi kwi-putty, inciphisa izinga lokunyuka kwamanzi e-putty, ngaloo ndlela iphucula kakhulu ukugcinwa kwamanzi kwi-putty. Oku kugcinwa kwamanzi kwenza i-putty ingabi lula ukuqhekeka okanye umgubo xa yakhiwe phantsi kobushushu obuphezulu okanye iimeko ezomileyo, ukwandisa ixesha lokuvula ukwakhiwa kunye nokuqinisekisa umgangatho we-putty layer.

Ukwandisa amandla ebhondi

Ukwandisa umxholo we-cellulose ether kunokuphucula ukunamathela kwe-putty kunye nokuqinisekisa ukuba i-putty ifakwe ngokuqinileyo kumphezulu wesiseko. Xa i-putty igalelwe, i-ether ye-cellulose ayinako ukunyusa kuphela ukuqina kwe-putty, kodwa inika iqondo elithile lokunamathela ngexesha lenkqubo yokomisa ukukhusela i-putty layer ukuba ingawi okanye i-warping. Oku kubaluleke kakhulu kwiindawo ezigudileyo kunye neziseko ezingenakufunxa kuba i-cellulose ether ibonelela ngeempawu ezongezelelweyo zokubambelela.

Lawula isantya sokumisa

I-ether ye-cellulose inokulungelelanisa isantya sokumisa i-putty ukwenzela ukuba i-putty layer inokoma ngokulinganayo, ngaloo ndlela ikhusela ngokufanelekileyo ukuqhekeka okubangelwa ukulahleka kwamanzi ngokukhawuleza phezu komhlaba. Ukwakhiwa kwe-putty ye-multi-layer, isantya esifanelekileyo sokumisa sibaluleke kakhulu, esiza ukuqinisekisa ukunamathela phakathi kweengqimba kunye nesiphumo esipheleleyo.

Phucula umsebenzi wokuchasana nokudodobala

Kwiindonga ezithe nkqo okanye iisilingi, i-putty ichaphazeleka lula ngumxhuzulane kwaye ineengxaki zokuthoba kunye nokuthoba. Umphumo wokuqina we-cellulose ether unokuphucula ngokufanelekileyo i-viscosity kunye nokuzinza kwe-putty, ukuthintela izinto ezivela kwi-sliding ngenxa yobunzima, kwaye uqinisekise ukuhanjiswa okufanayo kwe-putty.

3. Iintlobo eziphambili kunye nokukhethwa kwee-ether ze-cellulose

Iindidi ezahlukeneyo ze-cellulose ethers zineempembelelo ezahlukeneyo kwi-putty, kwaye kubaluleke kakhulu ukukhetha uhlobo olufanelekileyo lwe-cellulose ether. Ezi zilandelayo zizininzi ezisetyenziswa ngokuqhelekileyo ii-cellulose ethers kunye neempawu zazo:

IHydroxypropyl methylcellulose (HPMC): Inokuqina okulungileyo, ukugcinwa kwamanzi kunye neempawu zokwenza ifilimu kwaye isetyenziswa ngokubanzi kwi-putty yokwakha. I-HPMC inokuphucula kakhulu ulwakhiwo kunye neepropati zokwenza ifilimu ye-putty, yenza i-putty ibe lula xa ifakwe, kwaye iphucule ukunamathela kunye nokuguda kwe-putty.

I-Hydroxyethyl cellulose (HEC): Isetyenziswa kakhulu kwiinkqubo ezisekelwe emanzini, inamandla okulawula ukutyeba kunye ne-rheology, kwaye isoloko isetyenziswa kwi-putty yangaphakathi yodonga kunye neengubo ezisekelwe emanzini. I-HEC inesiphumo esibalulekileyo sokuphucula umgangatho wokugquma kwe-putty, kodwa ukugcinwa kwayo kwamanzi kungaphantsi kancinane kwi-HPMC.

I-Hydroxypropyl cellulose (HPC): I-HPC ine-viscosity ephezulu kunye nokuzinza okugqwesileyo, kwaye ifanelekile kwizihlandlo ezineemfuno eziphezulu zokuchasana ne-sagging. Ukongeza isixa esifanelekileyo se-HPC kwi-putty kunokuphucula kakhulu ukusebenza kokuchasa kunye namandla eputty.

4. Iinzuzo zesicelo kunye nethemba lemarike ye-cellulose ethers

Izibonelelo zokusetyenziswa kwe-cellulose ethers kwi-putty zibalulekile, ikakhulu zibonakaliswa kule miba ilandelayo:

Ukugcinwa kweendleko: I-ethers ye-cellulose inokuphucula ngokufanelekileyo ukusebenza kwe-putty, ukunciphisa inani lokuphinda kusebenze, kwaye ngoko ukunciphisa iindleko zempahla kunye nezabasebenzi.

Ukukhuselwa kwendalo: I-cellulose ethers zizinto zendalo ezenziwe kwimithombo ehlaziyiweyo, ngokukhuselwa kakuhle kwendalo, i-non-toxic kumzimba womntu, kunye nokunceda ukuhlangabezana neemfuno zezinto zokwakha zanamhlanje zokukhuselwa kokusingqongileyo okuluhlaza.

Ukuziqhelanisa neentlobo ezahlukeneyo zemozulu: Ukugcinwa kwamanzi kunye nokumelana nokuqhekeka kwe-cellulose ethers kwenza kube lula ukwakhiwa phantsi kweemeko zemozulu ezahlukeneyo, ukuhlangabezana neemfuno zeendawo ezahlukeneyo zokwakha ezifana nomntla owomileyo kunye nomzantsi omanzi.

Amathemba amahle emarike: Ngophuhliso lwezakhiwo eziluhlaza kunye nokunyuka kwemfuno yezinto zokwakha ezisebenza kakuhle, imfuno yemarike yeethers ze-cellulose njengezongezo eziphambili zonyukile unyaka nonyaka. Ngokukodwa kwishishini lokuhombisa, iimfuno zodonga lwe-flatness kunye nobuhle bomhlaba ziphuculwe, eziye zandisa indawo yophuhliso lweemveliso ze-putty. I-ether yeCellulose njengesilungisi iya kuba nethemba elikhulu lesicelo.
