Impuphu ye-putty yakhiwe kakhulu ngezinto ezakha ifilimu (izinto zokubopha), izigcwalisi, izinto zokugcina amanzi, izithisi, ama-defoamers, njll. Izinto zokusetshenziswa zamakhemikhali eziphilayo ezitholakala kumpuphu ye-putty zifaka phakathi: i-cellulose, isitashi esifakwe i-gelatinized, i-starch ether, i-polyvinyl alcohol, i-dispersible latex powder, njll. Ngezansi, i-Polycat izohlaziya ukusebenza kanye nokusetshenziswa kwezinto zokusetshenziswa zamakhemikhali ezahlukahlukene kuwe ngamunye ngamunye.
Ifayibha:
I-Fiber (US: I-Fiber; isiNgisi: I-Fiber) ibhekisela entweni eyakhiwe yizicucu eziqhubekayo noma ezingaqhubeki. Njenge-fibre yezitshalo, izinwele zezilwane, i-fibre yesilika, i-fibre yokwenziwa, njll.
I-cellulose:
I-Cellulose iyi-polysaccharide enkulu eyakhiwe yi-glucose futhi iyisakhi esiyinhloko sezindonga zamaseli ezitshalo. Ezingeni lokushisa legumbi, i-cellulose ayincibiliki emanzini noma ezinyibilikisini ezivamile ze-organic. Okuqukethwe kwe-cellulose kukotini kucishe kube yi-100%, okwenza kube umthombo wemvelo omsulwa we-cellulose. Ngokuvamile, i-cellulose ingama-40-50%, futhi kukhona i-10-30% ye-hemicellulose kanye ne-20-30% ye-lignin.
Umehluko phakathi kwe-cellulose (kwesokudla) nesitashi (kwesobunxele):
Ngokuvamile, kokubili isitashi kanye ne-cellulose kuyi-polysaccharides yama-macromolecular, futhi ifomula yama-molecule ingavezwa njenge-(C6H10O5) n. Isisindo sama-molecule se-cellulose sikhulu kunesesitashi, futhi i-cellulose ingabola ukuze kukhiqizwe isitashi. I-Cellulose iyi-D-glucose kanye ne-β-1,4 glycoside Ama-polysaccharides ama-macromolecular akhiwe ngama-bond, kuyilapho isitashi sakhiwa ngama-α-1,4 glycosidic bond. I-Cellulose ngokuvamile ayinamagatsha, kodwa isitashi sinamagatsha ngama-glycosidic bond angu-1,6. I-Cellulose ayincibiliki kahle emanzini, kanti isitashi sincibilika emanzini ashisayo. I-Cellulose ayizweli ku-amylase futhi ayishintshi ibe luhlaza okwesibhakabhaka uma ivezwa ku-iodine.
I-Ether ye-Cellulose:
Igama lesiNgisi elithii-cellulose etheryi-cellulose ether, okuyi-polymer compound enesakhiwo se-ether esenziwe nge-cellulose. Ingumkhiqizo wokusabela kwamakhemikhali kwe-cellulose (isitshalo) ne-ether ye-etherification. Ngokusho kokuhlelwa kwesakhiwo samakhemikhali kwe-substituent ngemuva kwe-etherification, ingahlukaniswa ibe yi-anionic, i-cationic kanye ne-nonionic ethers. Kuye nge-ether ye-etherification esetshenziswayo, 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-carboxymethyl hydroxyethyl cellulose kanye ne-phenyl cellulose, njll. Embonini yokwakha, i-cellulose ether ibizwa nangokuthi i-cellulose, okuyigama elingajwayelekile, futhi ibizwa ngokuthi i-cellulose (noma i-ether) ngendlela efanele.
Indlela Yokujiya Ye-Cellulose Ether Thickener:
Ama-thickener e-cellulose ether angama-thickener angewona ama-ionic aqina kakhulu ngokumanzisa kanye nokunamathelana phakathi kwama-molecule.
Uchungechunge lwe-polymer lwe-cellulose ether kulula ukwakha isibopho se-hydrogen namanzi emanzini, futhi isibopho se-hydrogen senza sibe nomswakama ophezulu kanye nokubanjwa kwama-molecule.
Laphoi-cellulose etherI-thickener ifakwa kupende we-latex, imunca inani elikhulu lamanzi, okwenza umthamo wayo wande kakhulu, inciphise isikhala samahhala se-pigments, ama-fillers kanye nezinhlayiya ze-latex;
Ngesikhathi esifanayo, amaketanga e-cellulose ether molecular axhumene ukuze akhe isakhiwo senethiwekhi esinezinhlangothi ezintathu, kanti ama-pigment, ama-filler kanye nezinhlayiya ze-latex zizungezwe phakathi kwe-mesh futhi azikwazi ukugeleza ngokukhululeka.
Ngaphansi kwale miphumela emibili, i-viscosity yesistimu iyathuthuka! Sifinyelele umphumela wokujiya esasiwudinga!
