Impushana ye-putty yakhiwa ikakhulukazi izinto zokwakha ifilimu (izinto ezibophayo), izigcwalisi, ama-ejenti agcina amanzi, ama-thickeners, ama-defoamers, njll. Izinto ezisetshenziswa amakhemikhali emvelo asetshenziswa ku-putty powder ikakhulukazi zifaka: i-cellulose, isitashi esise-pregelatinized, isitashi ether, i-polyvinyl alcohol, i-latex powder ehlakazekayo, njll. Ngezansi, i-Polycat izohlaziya ukusebenza kwakho okuhlukahlukene ngamakhemikhali ahlukahlukene.
I-Fiber:
I-Fiber (US: Fiber; English: Fiber) ibhekisela entweni eyakhiwe imicu eqhubekayo noma engaqhubeki. Okufana ne-plant fiber, izinwele zezilwane, i-silika fiber, i-synthetic fiber, njll.
I-Cellulose:
I-Cellulose iyi-macromolecular polysaccharide eyakhiwe nge-glucose futhi iyisakhi esiyinhloko sezindonga zamaseli ezitshalo. Ezingeni lokushisa lasekamelweni, i-cellulose ayincibiliki emanzini noma kuzincibilikisi ezivamile. Okuqukethwe kwe-cellulose kukotini kusondele ku-100%, okwenza kube umthombo wemvelo omsulwa we-cellulose. Ngokhuni jikelele, i-cellulose i-akhawunti ye-40-50%, futhi kukhona i-10-30% ye-hemicellulose kanye ne-20-30% ye-lignin.
Umehluko phakathi kwe-cellulose (kwesokudla) nesitashi (kwesokunxele):
Ngokuvamile, kokubili isitashi kanye ne-cellulose kuyi-macromolecular polysaccharides, futhi ifomula ye-molecular ingavezwa ngokuthi (C6H10O5) n. Isisindo samangqamuzana e-cellulose sikhulu kunesitashi, futhi i-cellulose ingabola ukuze ikhiqize isitashi. I-cellulose i-D-glucose kanye ne-β-1,4 glycoside Macromolecular polysaccharides eyakhiwe ngamabhondi, kuyilapho isitashi sakhiwe ngamabhondi e-α-1,4 glycosidic. I-Cellulose ngokuvamile ayinawo amagatsha, kodwa isitashi sihlanganiswa ngamabhondi angu-1,6 e-glycosidic. I-Cellulose ayincibiliki kahle emanzini, kuyilapho isitashi sincibilika emanzini ashisayo. I-Cellulose ayizweli ku-amylase futhi ayijiki ibe luhlaza okwesibhakabhaka lapho ichayeke ku-iodine.
I-Cellulose Ether:
Igama lesiNgisi elithii-cellulose etheri-cellulose ether, okuyinhlanganisela ye-polymer enesakhiwo se-ether esenziwe nge-cellulose. Kungumkhiqizo wokusabela kwamakhemikhali we-cellulose (isitshalo) nge-ejenti ye-etherification. Ngokuya ngesigaba sesakhiwo samakhemikhali se-substitute ngemva kokufakwa kwe-etherification, ingahlukaniswa ibe ama-anionic, cationic kanye nama-nonionic ether. Ngokuya nge-ejenti ye-etherification esetshenzisiwe, kukhona i-methyl cellulose, i-hydroxyethyl methyl cellulose, i-carboxymethyl cellulose, i-ethyl cellulose, i-benzyl cellulose, i-hydroxyethyl cellulose, i-hydroxypropyl methyl cellulose, i-cyanoethyl cellulose, i-benzyl cyanoethyl cellulose, i-carboxy cellulose, i-carboxy cellulose, i-carboxy cellulose njll. Embonini yezokwakha, i-cellulose ether ibizwa nangokuthi i-cellulose, okuyigama elingavamile, futhi ibizwa ngokuthi i-cellulose (noma i-ether) ngendlela efanele.
Indlela Yokuqinisa I-Cellulose Ether Thickener:
Ama-thickeners e-cellulose ether ayizingqimba ezingezona i-ionic ezijiya kakhulu ngokufakwa kwamanzi kanye nokugoqana phakathi kwama-molecule.
Iketango le-polymer le-cellulose ether kulula ukwakha isibopho se-hydrogen emanzini emanzini, futhi isibopho se-hydrogen siyenza ibe nokugeleza okuphezulu kwe-hydration kanye ne-inter-molecular entanglement.
Lapho i-i-cellulose etheri-thickener yengezwe kupende we-latex, idonsa amanzi amaningi, okwenza ivolumu yayo yande kakhulu, inciphisa isikhala samahhala sezingulube, izigcwalisi kanye nezinhlayiya ze-latex;
Ngesikhathi esifanayo, amaketanga e-cellulose ether yamangqamuzana ahlanganiswe ukuze enze isakhiwo senethiwekhi esinezinhlangothi ezintathu, futhi ama-pigments, ama-fillers kanye nezinhlayiya ze-latex zizungezwe phakathi kwe-mesh futhi azikwazi ukugeleza ngokukhululekile.
Ngaphansi kwale miphumela emibili, i-viscosity yesistimu iyathuthukiswa! Kuzuzwe umphumela wokujiya ebesiwudinga!
