Imikorere ya selulose ether muri minisiteri

Cellulose etherkubika amazi

Kubika amazi ya minisiteri bivuga ubushobozi bwa minisiteri yo gufata no gufunga amazi.Iyo hejuru ya viscosity ya selulose ether, niko gufata amazi neza.Kuberako imiterere ya selile irimo hydroxyl na ether, hydroxyl na ether ihuza itsinda rya atome ya ogisijeni na molekile zamazi kugirango bahuze hydrogène, kuburyo amazi yubusa mumazi ahuza, amazi yumuyaga, kugirango bigire uruhare mukubungabunga amazi.

Ibisubizo byaselile ether

1. Ether ya coarser selulose ether iroroshye gukwirakwiza mumazi nta guhunika, ariko igipimo cyo gusesa kiratinda cyane.Ether ya selile iri munsi ya mesh 60 yashonga mumazi muminota 60.

2. Ibice byiza bya selulose ether mumazi biroroshye gutatanya kandi ntabwo ari agglomerate, kandi igipimo cyo gushonga kiringaniye.Cellulose ether irenga mesh 80 yashonga mumazi mugihe cyiminota 3.

3. Ultrafine selulose ether ikwirakwira vuba mumazi, igashonga vuba kandi ikabyara vuba.Cellulose ether iri hejuru ya mesh 120 yashonga mumazi mumasegonda 10-30.

Nibyiza bya selile ya ether selile, niko gufata amazi neza, uduce duto twa selulose ether hamwe nubuso bwamazi byahise bishonga kandi bikora gel phenomenon.Kole ipfunyika ibikoresho kugirango irinde molekile y'amazi gukomeza kwinjira.Rimwe na rimwe, kabone niyo byaba bimaze igihe kinini, igisubizo ntigishobora gutatana no gushonga, bigakora igisubizo cyuzuye ibyondo cyangwa agglomerate.Ibice byiza biratatana kandi bigashonga ako kanya iyo uhuye namazi kugirango bibe byiza.

PH agaciro ka selile ether (gutinda coagulation cyangwa imbaraga za kare)

Agaciro PH k'abakora selile ya ether mugihugu ndetse no mumahanga igenzurwa cyane nka 7, ni acide.Kuberako haracyari byinshi byamazi ya glucose yimyunyu ngugu mumiterere ya molekulire ya selile ya selile, impeta ya glucose idafite umwuma nitsinda nyamukuru ritera sima gutinda.Impeta ya glucose idafite umwuma irashobora gukora calcium ion mugisubizo cya hydrata ya sima ikora isukari ya calcium ya molekile ya sukari, igabanya ubukana bwa calcium ion mugihe cyo kwinjiza sima, ikarinda gushiraho no kugwa kwa calcium hydroxide na kristu yumunyu wa calcium, bityo bikadindiza inzira yo gufata sima.Niba agaciro ka PH gahindutse alkaline, mortar izagaragara hakiri kare imbaraga.Ubu inganda nyinshi zo guhindura agaciro ka PH ukoresheje karubone ya sodium, karubone ya sodium nubwoko bwihuta, sodium karubone irashobora kunoza imikorere yubutaka bwa sima, bigatuma ubufatanye hagati yibice byiyongera, bikarushaho kunoza ububobere bwa slurry, mortar na sodium karubone na calcium ion ivanze byihuse, byatumye habaho ettringite, sima ya sima vuba.Kubwibyo, agaciro ka PH kagomba guhinduka ukurikije abakiriya batandukanye mubikorwa nyirizina.

Cellulose ether gaze

Umwuka winjira muri selile ya selile ahanini ni ukubera ko selile ether nayo iba igaragara, ibikorwa byimikorere ya selile ya selile ahanini biboneka mumasoko ya gaze-yamazi-akomeye, icya mbere nukumenyekanisha ibibyimba, bigakurikirwa no gutatana no gutose.Ether ya selile irimo groupe ya alkyl, igabanya cyane uburemere bwubuso nimbaraga zamazi hagati yamazi, igisubizo cyamazi mugikorwa cyo guhagarika umutima biroroshye kubyara utubuto duto duto duto.

Gelation ya selile ether

Cellulose ether yashonga muri minisiteri kubera urunigi rwayo rwa mikorerexy na hydroxypropyl groupe muri slurry hamwe na calcium ion na aluminium ion mugukora gel viscous kandi ikuzuzwa icyuho cya sima, kuzamura ubwinshi bwa minisiteri, bigira uruhare mukuzuza byoroshye kandi gushimangira.Ariko, mugihe matrike ikomatanyirijwe hamwe, polymer ntishobora gukina inkunga ikomeye, bityo imbaraga nogusenyuka kwa minisiteri bigabanuka.

Gukora firime ya selile ether

Filime yoroheje ya latex ikorwa hagati ya selile ya ether na sima nyuma ya hydration.Firime igira kashe kandi itezimbere ubuso bwumye bwa minisiteri.Kuberako ether ya selile ifite amazi meza, gumana molekile zamazi zihagije imbere mumbere ya minisiteri, bityo ukomeze imbaraga za hydrata ya sima no gukomera no gutera imbere rwose, kunoza imbaraga zihuza za minisiteri, icyarimwe kunoza gufatana na sima. minisiteri, minisiteri ifite plastike nziza nubukomere, gabanya guhindagurika kwa minisiteri.
