I-Hydroxypropylyll starch ether (HPS)na-I-Cellulose Etherzingezengeluzi zezengezo ezimbili ezivamile zamakhemikhali, ezisetshenziswa kabanzi ezintweni zokwakha, njengodaka, i-putty powder, ukumboza, njll. Yize zinokufana kwezici eziningi njengemithombo yezinto ezibonakalayo, izakhiwo zamakhemikhali, izakhiwo zemvelo , imiphumela yohlelo lokusebenza, nezindleko.
1. Imithombo Yezinto Ezibonakalayo Nezinhlaka Zamakhemikhali
I-Hydroxypropylyll starch ether (HPS)
I-HPS isuselwe esitashilweni semvelo futhi itholwe ngokusabela kokuguqulwa kwe-ethershition. Izinto zayo eziphambili ezilukhuni zingamabele, ukolweni, amazambane nezinye izitshalo zemvelo. Ama-molecule e-starch ahlanganiswa ama-glucose amayunithi axhumeke ama-α-1,4-glycosidic bond kanye nenani elincane le-α-1,6-glycosidic bond. Ngemuva kwe-hydroxypropylication, kungeniswa i-hydrophilic hydroxypropyl Group kulesi sakhiwo samangqamuzana e-HPS, siwunikeze imisebenzi ethile yokuqina, yokugcina amanzi kanye nemisebenzi yokuguqulwa.
I-Cellulose Ether
Abathakathi beCellulose basuselwa ku-cellulose yemvelo, njengokotini noma ngokhuni. I-cellulose yakhiwa ama-glucose amayunithi axhumene nezibopho ze-β-1,4-glycosidic. Abakwa-Collulose Bather Common Commone bafaka i-hydroxypropyll methylcellulose (HPMC), i-methylcellulose (MC), i-hydroxyethyl cellulose (i-njll), njll. Lezi zinhlaka ziveza ukufakwa okuhlukile ngokungezwani okuthe xaxa futhi kube nokuqina kwamakhemikhali.
2. Izakhiwo ezibonakalayo
Izici zokusebenza kwe-HPS
Ukuqina: I-HPS inomphumela omuhle wokuqina, kepha uma iqhathaniswa ne-cellulose ether, amandla ayo okuqina abuthakathaka kancane.
Ukugcinwa kwamanzi: I-HPS inokugcinwa kwamanzi okulinganiselwe futhi ilungele izinto zokwakha ezakhiwe eziphansi.
Ukusebenza: I-HPS ingathuthukisa ukusebenziseka kodaka futhi inciphise i-sagging ngesikhathi sokwakha.
Ukumelana Nezinga lokushisa: I-HPS iyazwela kakhulu izinga lokushisa futhi lithinteka kakhulu ngokushisa okukhona.
Izici zokusebenza ze-Cellulose Afers
Ukuqina
Ukugcinwa kwamanzi
Ukusebenza: I-CelLose Err ihle kakhulu ekuthuthukiseni ukusebenza futhi inganciphisa ngempumelelo izinkinga ezifana nokuqhekeka nokuphindwa yimpuphu.
Ukumelana Nezinga lokushisa: I-CelLose Ether inokuvumelana okuqinile kwezinguquko zokushisa kanye nokusebenza okuzinzile.
3. Imiphumela yohlelo lokusebenza
Umphumela wohleloI-HPS
Udaka olomile, i-HPS ikakhulukazi idlala indima yokwenza ngcono ukukwenza, ngcono ukugcinwa kwamanzi, kanye nokunciphisa ukunxusa nokuhlukaniswa. Kungokomnotho futhi kufanelekile ukusetshenziswa kwizimo ezinezidingo eziphezulu zokulawulwa kwezindleko, njenge-Interior Coll Wall Wall Putty Powder, Floorle Feral Gentar, njll.
Umphumela wohlelo lokusebenza le-cellulose ether
I-Cellulose AfersIsetshenziswa kabanzi ku-maspars osebenza kakhulu, izinamathiseli ze-tile, izinto ezisekelwe ku-gypsum nezinhlelo zangaphandle zokufakelwa kodonga lwangaphandle. Izakhiwo zalo eziphakeme eziphakeme kanye nokugcina amanzi zingathuthukisa kakhulu amandla e-bonding kanye nokushintshwa kokusebenza kwezinto ezibonakalayo, futhi zilungele ikakhulukazi amaphrojekthi anezidingo eziphakeme ekusebenzeni kwezokwakha futhi aqede ikhwalithi yomkhiqizo.
4. Izindleko kanye nokuvikelwa kwemvelo
Izindleko:
I-HPS inezindleko eziphansi futhi ilungele ukusetshenziswa ezimakethe ezibucayi ngentengo. I-Cellulose Afers iyabiza kakhulu, kepha isebenza kahle kakhulu futhi ingabizi kakhulu ekufuneni amaphrojekthi wokwakha.
Ukuvikelwa Kwezemvelo:
Zombili zithathwe ezintweni zemvelo futhi zinezakhiwo ezinhle zezemvelo. Kodwa-ke, ngoba ama-reagents amakhemikhali ambalwa adliwa kwinqubo yokukhiqiza ye-HPS, kungaphansi komthwalo wemvelo.
5. Isisekelo sokukhetha
Izidingo Zokusebenza: Uma unezidingo eziphakeme zokuqina kanye nezindawo zokugcina amanzi, kufanele ukhethe i-cellulose ether; Kwezinto zokwenziwa ezibucayi kakhulu kodwa zidinga ukuthuthuka okuthile ekusebenzeni, ungacabanga ngokusebenzisa i-HPS.
Izimo Zokusetshenziswa: Ukwakhiwa Okushisa Okuphezulu, Ukufakwa Kwangaphandle Kwangaphandle, Ukunamathela Kwama-Tile nezinye izimo ezidinga ukwesekwa okuphezulu zilungele ukwesekwa kokusebenza okuphezulu zilungele kakhulu i-ether ye-cellulose ether; Ngodonga olujwayelekile lwamandla ama-putty noma udaka oluyisisekelo, i-HPS inganikeza izixazululo ezomnotho nezisebenzayo.
I-Hydroxypropyll starch etherna-I-Cellulose Ether Ngamunye unobuhle babo futhi badlala izindima ezahlukahlukene ezintweni zokwakha. Ukukhethwa kudinga ukubhekwa ngokuphelele ngokususelwa kuzidingo zokusebenza, ukulawulwa kwezindleko, indawo yokwakha kanye nezinye izinto zephrojekthi ethile ukuze uzuze umphumela omuhle kakhulu.
