Iimveliso zesamente, ezinjengekhonkrithi, udaka, kunye nezinye izinto zokwakha, zisetyenziswa ngokubanzi kwizakhiwo zanamhlanje. I-selsulose ens (ezinjenge-hydroxypropyl methylcelcelgalose (i-HPMC), iHpmcroxythl Methylcelcelcelse (hemc), njl. Njl.). Ukuze kufezekiswe ezi ndawo zibalaseleyo, kubalulekile ukuba ifumane inkosi kwaye ulawule intsebenzo ye-Selesese.
1. Iipropathi ezisisiseko nemisebenzi ye-selulose
I-Seleculose Talsulose yiklasi ye-scrivietes zekhemikhali ye-Selelose yeNdalo, apho iqela le-hydroxyl litshintshwe kwiqela le-ether ngokusebenzisa i-ethe test. Iindidi ezahlukeneyo zeselpulose Taluped zinokuthathwa ngohlobo kunye nenani lezixhobo, kunye nohlobo ngalunye zinendima eyahlukileyo kwiimveliso zesamente.
I-Viscosity yeSeluplose
I-viscosity ye-seluplose youn ngqo ichaphazela ngqo i-RUOOOOOOOLOGH NOZIKO BENKONZO YAMABANDLA. I-viscofity ye-villyusity yeselula iphumelela ukugcinwa kwamanzi kunye nokwahlula kwamandla okuncamathisela, kodwa kungancitshisela ulwelo lwayo. I-viscofity ye-villfoety yeselula inceda ukuphucula ukwenziwa kunye nolwelo.
Inqanaba lokufakwa endaweni (DS) kunye ne-molar
Inqanaba lokufaka endaweni kunye ne-molar Inqanaba eliphezulu lokufaka endaweni kunye ne-molar eliphezulu le-molar linokuhlala liphucula ukugcinwa kwamanzi kunye nokuzinza kwe-selulose e kanithu.
Ukungasebenzi kwe-seluplose tan:
Ireyithi yokuchithwa kunye nokususwa kwe-selulose ebhutsi kuchaphazela ukufana kwesamente. I-seluplose ensulity elungileyo ingenza isisombululo esifanayo ngokukhawuleza, ngaloo ndlela iqinisekisa ukufana nokungazinzanga.
2. Khetha i-selsulose efanelekileyo
Imeko eyahlukeneyo yesicelo ineemfuno ezahlukeneyo zomsebenzi weeLwibhu. Ukukhetha uhlobo olufanelekileyo kunye nokucaciswa kwe-etelulose i-ete inokuphucula kakhulu ukusebenza kweemveliso zesamente:
Binders:
Kwizicelo ezinjengeetrothens kunye nendawo yokufakelwa i-plaster, i-viscofity ephezulu (njenge-HPMC) inokubonelela ngobambiso obungcono kunye nokuhlala okungapheliyo, ngaloo ndlela ukuphucula ukusebenza kwamandla okwakha.
Izinto zokugcina amanzi:
Kwimigangatho yokuzilinganisa kunye nezifaki ezikwimo yesamente, ezikwimo yesamente, isellulose ebhaka enamanzi (ezinje nge-HMC) ziyafuneka. Ukugcinwa kwamanzi aphezulu kuyanceda ukukhusela ukulahleka kwamanzi ngaphambi kwexesha, ngaloo ndlela kuqinisekisa ukuba ixesha elide lokusebenza.
Ukuqinisa izixhobo:
Iseli
I-3. Yandisa indlela yokongeza
Ukulawulwa kwendlela yongezwa kwe-seluplose i-ether kwiimveliso zesamente kubalulekile ukukhulisa ukusebenza kwalo. Ezi zinto zilandelayo zinendlela eqhelekileyo yokufezekisa:
INDLELA YOKUZIPHATHA:
Hlanganisa i-itelulose ether kunye neminye yezixhobo ezomileyo zepokotho kwangaphambili. Le ndlela inokuphepha ukwakhiwa kwe-agegloumeration ye-taryulose ether emva konxibelelwano ngqo namanzi, ngaloo ndlela iqinisekisa ukusasazeka kwayo kwi-slirry.
Indlela yokudibanisa emanzi:
Yongeza i-Sell Sether ukuya kwi-CEATE FELY ngokuthe ngcembe. Le ndlela ilungele imeko apho i-cleuluplose inyibilikisi ngokukhawuleza kwaye inceda ekwenzeni ukumiswa ngokuzinzileyo.
Indlela yoMbutho
Kwinkqubo yokulungiselela isamente se-Slamente, ukongeza i-IletEese Ether kwiziseko kunokuqinisekisa ukusasaza kwalo kwinkqubo yokulungiselela kwaye kuncitshiswe ukwahluka.
4. Lawula izinto zangaphandle
Izinto zangaphandle ezinjengobushushu, ixabiso le-PH, kunye nexabiso elishukumisayo linefuthe elibonakalayo kwintsebenzo ye-Selese.
Ulawulo lobushushu:
Ukuluka kunye nokubonisa i-viscosity ye-seluplose i-ether inomdla kakhulu kubushushu. Amaqondo obushushu aphezulu anceda i-Seleculose TOTE ukuze inyibilike ngokukhawuleza, kodwa inokudala ukubonwa kwesisombululo ukuze kunciphe. Iqondo lobushushu kufuneka lihlengahlengiswe ngokwemeko ethile yesicelo sokuqinisekisa ukuba ukwenziwa ngokugqibeleleyo kunye nokusebenza.
Uhlengahlengiso: Ixabiso le-pH yesamente i-state lihlala likuluhlu oluphezulu lwe-alkaline, ngelixa i-solity kunye nokubonisa i-seluplose i-tluctuate eguqukayo ngotshintsho lwexabiso le-pl. Ukulawula ixabiso le-pH kuluhlu olufanelekileyo kunokuzinzisa intsebenzo ye-Selelose Ether.
Inqanaba elixhokonxa: Iqondo elixhokonxa ichaphazela isiphumo sokusasazeka kwe-seluplose ether kwi-centence paste. Ireyithi ephezulu yokuvuselela inokuthi ikhokelele kwintshayelelo yomoya kunye nokudityaniswa kwe-selsulose ether, ngelixa ireyithi ye-scoring enomdla inceda ukuhambisa ngokulinganayo kwaye inyibilike i-ether.
5. Uhlalutyo lwetyala kunye neengcebiso ezisebenzayo
Ngohlalutyo lokwenyani, sinokusiqonda ngakumbi isicwangciso sesicelo kunye nesicwangciso sokuphucula i-selsulose ether kwiimveliso ezahlukeneyo zesamente:
Ukusebenza nzima kwe-tile Ngokwazisa i-HMEC egcina amanzi aphezulu kunye nokulungelelanisa isixa sayo songezelelo kunye nendlela yongezelelo (usebenzisa i-PROITTE indlela yokugcina), ukugcina amanzi
Izinto ezizezinye zezinto ezenziweyo: Izinto ezizezinye zokuziqhelanisa ezisetyenzisiweyo kwiprojekthi ethile zazinobugwenxa obuhlwempuzekileyo kunye neflethi engaphantsi emva kokwakha. Ngokukhetha i-HPMC ye-HPMC ye-HPMC kunye nokwenza iqondo lokuvuselela kunye nokulawulwa kweqondo lobushushu, ulwelo nendlela yokusebenza ngokwakhiwa kwesilayidi iphuculwe, senza umgangatho wokugqibela umphezulu.
Ukulawula ukusebenza kwe-Teluplose Ether kwiimveliso zesamente yeyona nto iphambili ekuphuculeni intsebenzo kunye nomgangatho wokwakha. Ngokukhetha uhlobo olufanelekileyo lwe-selsulose i-ether, ukulungiselela izinto zongeziweyo, kunye nokulawula izinto eziphathekayo, iimpawu eziphambili zeemveliso zesamente ezinje ngokugcinwa kwamanzi ezifana nokugcinwa kwamanzi, kunye nolwelo olunokuphuculwa kakhulu. Kwizicelo ezisebenzayo, kuyimfuneko ukuze uqiniseke ngokuqhubekayo kwaye uhlengahlengise ukusetyenziswa kwe-selsulose ether ngokweemfuno ezithile kunye neemeko zesicelo zokufezekisa iziphumo ezilungileyo.
