Ama-cellulose ethers ayizithako ezivamile ezisetshenziswa ekukhiqizeni amapende nezingubo ezifana ne-putty powder.I-Putty iyi-filler esekwe kwimpushana esetshenziselwa ukugcwalisa izikhala, imifantu nezimbobo kunoma iyiphi indawo.I-Cellulose ether ithuthukisa ikhwalithi ye-putty powder ngokuthuthukisa ukunamathela kwayo, ukuhlangana kanye nezinye izinto ezibonakalayo.Uma ukhetha ama-cellulose ethers we-putty powder, kufanele kuthathwe izinyathelo zokuqapha ukuze kuqinisekiswe umphumela wekhwalithi ephezulu.
Inikeza isiqondiso esibanzi ezindabeni okufanele zinakwe lapho kukhethwa i-cellulose ether ye-putty powder.
Qaphela #1: Thola uhlobo lwe-cellulose ether edingekayo
Kunezinhlobo ezahlukene ze-cellulose ethers, okuhlanganisa i-methylcellulose, i-ethylcellulose, i-hydroxyethylcellulose, i-hydroxypropylcellulose, ne-carboxymethylcellulose.Uhlobo ngalunye lwe-cellulose ether lunezinto ezihlukile ezilwenza lufanelekele izinhlelo zokusebenza ezithile.Ngakho-ke, ngaphambi kokukhetha i-cellulose ether ye-putty powder, kuyadingeka ukunquma uhlobo lwe-cellulose ether olufanele uhlobo lwe-putty powder olukhiqizwayo.
Isibonelo, i-hydroxyethyl cellulose (HEC) ifaneleka kahle ukusetshenziswa kuma-putty powders ngoba ithuthukisa izakhiwo ze-rheological ze-putty powder.I-HEC ishubisa ikhambi, ivimbele ukuwohloka, futhi ikhulise i-viscosity ye-putty powder.I-Methylcellulose, ngakolunye uhlangothi, ayifanele ukusetshenziswa ku-putty powder ngoba ayinayo indawo yokuqina efana ne-HEC.
Inothi #2: Thola ibanga le-cellulose ether edingekayo
Ama-cellulose ether atholakala ngamamaki ahlukene kuye ngobumsulwa nokugxilisa ingqondo.Uhlobo lwe-cellulose ether oludingekayo ku-putty powder kufanele lunqunywe ngokuvumelana nezidingo ze-putty powder.
Amabanga aphezulu ama-cellulose ethers akhethwa ngaphezu kwe-cellulose ethers yezinga eliphansi ngoba aqinisekisa ukusebenza okungaguquki kwe-putty powder.I-high-purity cellulose ether ayiqukethe umlotha, izinsalela nokunye ukungcola okuthinta ikhwalithi ye-putty powder.
Qaphela #3: Ukuhlola Ukunyibilika Kwe-Cellulose Ethers
Ama-cellulose ethers ayancibilika emanzini, kodwa izinga lokuncibilika liyahlukahluka kuye ngohlobo lwe-cellulose ether.IHydroxypropylcellulose (HPC) iyisibonelo se-cellulose ether engancibiliki emanzini;kunalokho, ihlakazeka kalula emanzini.
Kubalulekile ukunquma ukuncibilika kwe-cellulose ether esetshenziswa ku-putty powder ukuze kuqinisekiswe ukuthi incibilika kalula emanzini futhi ingabangeli noma yikuphi ukugoqa noma ukungahambisani ku-putty powder.
Qaphela #4: Cabangela Izinga Lokushisa Lokusebenza
Ukushisa kokwakhiwa kwe-putty powder cellulose ether nakho kubalulekile ukucatshangelwa.Uhlobo ngalunye lwe-cellulose ether lunebanga elithile lokushisa elisebenza kahle kakhulu.Ngakho-ke, kubalulekile ukukhetha ama-cellulose ethers angakwazi ukumelana nezinga lokushisa lokwakhiwa kwe-putty powder.
I-cellulose ether inokuqina okuhle kokushisa futhi ifanele ukusetshenziswa ku-putty powder ngoba ngeke ilulaze noma ihluleke emazingeni okushisa aphezulu.I-Hydroxypropyl methylcellulose (HPMC) iyisibonelo se-cellulose ether eqinile ngokushisa futhi isebenza kahle ku-putty powder.
Inothi #5: Hlola Izimo Zesitoreji
Ama-cellulose ethers ayazwela ekushintsheni kwezinga lokushisa kanye nomswakama;ngakho-ke, kufanele zigcinwe ngaphansi kwezimo ezithile ukuze zigweme ukuwohloka.Ama-cellulose ethers kufanele agcinwe endaweni eyomile enezinga lokushisa elilawulwayo kanye nomswakama ukuze kuqinisekiswe ukuzinza kwawo.
Ama-cellulose ether aqinile athuthukisa ikhwalithi ye-putty powder, ayenze ingaguquguquki, iqine futhi iphumelele.
Isexwayiso #6: Landela izinyathelo zokuphepha
Ngesikhathi senqubo yokukhiqiza, kufanele kuthathwe izinyathelo zokuvikela ukuvikela ukuchayeka kwabasebenzi kuma-cellulose ethers.Lapho uphatha ama-cellulose ethers, kubalulekile ukuthi ugqoke izinto zokuzivikela ezifana namagilavu, izibuko, nezihlangu zobuso ukuze ugweme ukuthinta isikhumba, amehlo, noma isimiso sokuphefumula.
Ukwengeza, kubalulekile ukulebula iziqukathi ezine-cellulose ether ezinezimpawu eziyisixwayiso eziyingozi futhi ulandele izindlela ezifanele zokulahla ukuze ugweme ukungcoliswa kwemvelo.
Ekuphetheni
Ukukhetha i-cellulose ether efanele ye-putty powder kubalulekile ukuze uthole imiphumela yekhwalithi ephezulu.Kudingeka kuthathwe izinyathelo zokuqapha lapho kunqunywa uhlobo nebanga le-cellulose ether edingekayo, kuhlolwa ukunyibilika kwayo nokuzinza kokushisa, kubambelela ezimweni ezifanele zokulondoloza, kanye nokulandela izinyathelo zokuphepha.
Ukuthatha lezi zinyathelo zokuphepha akuqinisekisi kuphela izinga le-putty powder, kodwa futhi kuvikela abasebenzi kanye nemvelo.Ngokusebenzisa i-cellulose ether efanele, i-putty powder ingakhiqizwa ngokuphepha nangempumelelo ukuze kuhlangatshezwane nezidingo zamakhasimende zekhwalithi nokuvumelana.
