Gutezimbere ingaruka za hydroxypropyl methyl selulose kubikoresho bishingiye kuri sima

Mu myaka yashize, hamwe niterambere ryikomeza ryiterambere rya tekinoroji yubushyuhe bwo hanze, iterambere ryikomeza rya tekinoroji ya hydroxypropyl methyl selulose, hamwe nibiranga ibyiza bya hydroxypropyl methyl selulose HPMC ubwayo, hydroxypropyl methyl selulose HPMC yakoreshejwe cyane mubikorwa byubwubatsi.

gushiraho igihe

Gushiraho igihe cya beto bifitanye isano cyane nigihe cyo gushiraho sima, kandi igiteranyo ntigifite ingaruka nke.Kubwibyo, igihe cyo gushiraho minisiteri kirashobora gukoreshwa mugusimbuza ubushakashatsi ku ngaruka za HPMC ku gihe cyagenwe cy’amazi yo munsi y’amazi adatatanye.Kubera ko igihe cyagenwe cya minisiteri kigira ingaruka ku kigereranyo cya sima y’amazi no ku kigereranyo cy’umusenyi wa sima, kugira ngo hamenyekane ingaruka za HPMC ku gihe cyagenwe cya minisiteri, ni ngombwa gukosora igipimo cya sima y’amazi n’umusenyi wa sima wa minisiteri.

Ubushakashatsi bwakozwe bwerekana ko kwiyongera kwa HPMC bigira ingaruka mbi ku mvange ya minisiteri, kandi igihe cyo gushiraho minisiteri cyiyongera hamwe no kwiyongera kwa selile ether HPMC.Hamwe na HPMC ingana, igihe cyo gushiraho minisiteri yakozwe munsi y'amazi ni kirekire kuruta icyakozwe mu kirere.Iyo upimye mumazi, igihe cyo gushiraho minisiteri ivanze na HPMC ni 6 ~ 18h nyuma mugushiraho kwambere na 6 ~ 22h nyuma mugihe cyanyuma kuruta icy'ubusa.Kubwibyo, HPMC igomba gukoreshwa hamwe nimbaraga zo hambere.

HPMC ni polymer ifite imiterere yumurongo wa macromolecular, hamwe nitsinda rya hydroxyl kumatsinda ikora, rishobora gukora hydrogène ihuza kuvanga molekile zamazi kugirango byongere ubwiza bwo kuvanga amazi.Iminyururu miremire ya HPMC izakurura, itume molekile ya HPMC ihurira hamwe kugirango ibe imiterere y'urusobe, no gupfunyika sima no kuvanga amazi.Nkuko HPMC ikora imiterere y'urusobekerane rusa na firime kandi igapfunyika sima, irashobora gukumira neza ihindagurika ryamazi muri minisiteri kandi ikabangamira cyangwa igabanya umuvuduko wa sima.

Amaraso

Ikintu cyo kuva amaraso ya minisiteri isa nki ya beto, izatera gutuza gukomeye kwinshi, kongera igipimo cya sima yamazi yikigero cyo hejuru, bigatuma igorofa yo hejuru igabanuka rya plastike nini, cyangwa igacika mugihe cyambere, n'imbaraga z'ubuso bworoshye ni nkeya.

Iyo igipimo kirenze 0.5%, mubusanzwe nta maraso aba.Ibi ni ukubera ko iyo HPMC ivanze na minisiteri, HPMC iba ifite firime na firime ya reticular, kimwe na adsorption ya hydroxyl kumurongo muremure wa macromolecule, bigatuma sima no kuvanga amazi muburyo bwa minisiteri bigenda neza, bigatuma imiterere ihamye ya minisiteri.Iyo HPMC yongeweho kuri minisiteri, ibyinshi byigenga bito bizashirwaho.Ibibyimba bizagabanywa neza muri minisiteri kandi bibangamire gushira hamwe.Iyi mikorere ya tekiniki ya HPMC igira ingaruka zikomeye kubikoresho bishingiye kuri sima, kandi ikoreshwa kenshi mugutegura ibintu bishya bishingiye kuri sima nka minisiteri yumye na polymer mortar, kuburyo bifite amazi meza hamwe na plastike.

Amazi ya minisiteri

Iyo ingano ya HPMC ari nto cyane, igira ingaruka zikomeye kumazi ya minisiteri.Ukurikije ko kwaguka kwa minisiteri nshya ari bimwe, ingano ya HPMC hamwe n’amazi akenerwa na minisiteri ihinduka ku buryo bugaragara mu gihe runaka, kandi amazi ya minisiteri agabanuka mbere hanyuma akiyongera.Iyo ibirimo HPMC biri munsi ya 0.025%, hamwe no kwiyongera kwa HPMC, amazi ya minisiteri aragabanuka kurwego rumwe rwo kwaguka, ibyo bikaba byerekana ko uko HPMC ari ntoya, ingaruka zigabanya amazi ya minisiteri.Ingaruka yinjira mu kirere ya HPMC ituma minisiteri igira umubare munini w’ibibyimba bito byigenga, bigira uruhare mu gusiga no kunoza amazi ya minisiteri.Iyo igipimo kirenze 0.025%, amazi akenerwa na minisiteri yiyongera hamwe no kwiyongera kwa dosiye, ibyo bikaba biterwa nubusugire bwimbitse bwimiterere y'urusobe rwa HPMC, kugabanya ikinyuranyo hagati ya floc kumurongo muremure wa molekile, gukurura no guhuriza hamwe, no kugabanya amazi ya minisiteri.Kubwibyo, iyo impamyabumenyi yo kwaguka ahanini ari imwe, ibicucu byerekana ubwiyongere bwamazi akenewe.
