Hydroxypropyl Methyl Cellulose HPMC
1. Ifite ituze kuri aside na alkali, kandi igisubizo cyamazi cyacyo kirahagaze neza murwego rwa pH = 2 ~ 12. Soda ya Caustic n'amazi ya lime ntabwo bigira ingaruka nyinshi mubikorwa byayo, ariko alkali irashobora kwihutisha umuvuduko wayo kandi igateza imbere ubwiza bwayo.
2. HPMCni uburyo bwiza bwo kubika amazi kuriicyuma cyumyesisitemu, ishobora kugabanya umuvuduko wo gusohora amabuye ya minisiteri no gutondekanya, kunoza ubufatanye bwa minisiteri, kubuza neza ishyirwaho rya plastike ya minisiteri, no kugabanya igipimo cya plastike ya minisiteri.
3, ni electrolyte itari ionic na non-polymeric electrolyte, ihagaze neza mubisubizo byamazi yumunyu wicyuma na electrolytike kama, kandi irashobora kongerwaho mubikoresho byubwubatsi igihe kirekire kugirango irambe neza.
4, imikorere yimikorere ya minisiteri yatejwe imbere kuburyo bugaragara, minisiteri isa nkaho ifite "amavuta", irashobora gutuma urukuta ruhuza uruzitiro rwuzuye, rusa neza, kuburyo minisiteri nuburinganire bwibanze, kandi bishobora kongera igihe cyo gukora.
Kubika amazi
Kumenya gukira imbere bifasha kunoza imbaraga zigihe kirekire, kubuza kuva amaraso, gukumira gutura minisiteri, kugabanuka no kunoza imirwanyasuri.
Kubyimba
Irinde amacakubiri, utezimbere uburinganire bwa minisiteri, utezimbere imbaraga zifatika, kandi unoze imikorere irwanya kumanikwa.
Kwinjira mu kirere
Kunoza imikorere ya minisiteri. Hamwe nubwinshi bwimikorere ya selile, niko urunigi rurerure, niko bigaragara ingaruka zo kwinjiza umwuka.
Gutinda gukererwa
Gufatanya no gufata amazi kugirango wongere igihe cyo gufungura minisiteri
Hydroxypropyl Starch ether
1.
2. Ether ya krahisi irimo hydroxypropyl itandukanye ifite ubushobozi butandukanye bwo gufasha selile mu kugumana amazi kuri dosiye imwe.
3. Gusimbuza itsinda rya hydroxypropyl byongera urugero rwo kubyimba mumazi kandi bigabanya umwanya wo gutembera kwingirangingo, bityo bikagera ku ngaruka zo kubyimba no kwiyegereza kwiyongera.
Thubotropic lubricity
Ether ya etarike ikwirakwizwa vuba muri sisitemu ya minisiteri, ihindura rheologiya ya minisiteri ikayiha thixotropy. Iyo imbaraga zo hanze zashyizwe mu bikorwa, ubwiza bwa minisiteri buzagabanuka, byemeze kubaka no kuvoma neza, no kubiha thixotropy. Ifite ibyiyumvo byiza. Iyo imbaraga zo hanze zavanyweho, ubwiza bwiyongera, butanga minisiteri nziza yo kugabanuka. Mu ifu yuzuye, ifite ibyiza byo kuzamura urumuri rwamavuta ya peteroli no kumurika.
Ingaruka yo gufata amazi yingirakamaro
Starike ether ubwayo ifite hydrophilique kubera uruhare rwamatsinda ya hydroxypropyl muri sisitemu. Iyo uhujwe na selile cyangwa ukongerwaho muburyo runaka kuri minisiteri, birashobora kongera gufata amazi kurwego runaka kandi bigahindura igihe cyo kumisha hejuru.
Kurwanya-sag no kurwanya kunyerera
Ingaruka nziza zo kurwanya-sag n'ingaruka nziza.
Ifu ya polymer isubirwamo
1. Kunoza imikorere ya minisiteri.Ifu isubirwamor or RDPibice bitatanye muri sisitemu, biha sisitemu amazi meza no kunoza imikorere no gukora bya minisiteri.
2. Kunoza imbaraga zo guhuza za minisiteri. Ifu ya reberi imaze gukwirakwizwa muri firime, ibintu bidafite umubiri na organic muri sisitemu ya minisiteri birashobora guhuzwa hamwe. Turashobora kwiyumvisha ko sima n'umucanga muri minisiteri ari amagufwa, kandi ifu ya latex ikora ligaments. Ihuriro ryiyongera, imbaraga ziriyongera, kandi imiterere ihinduka ihinduka buhoro buhoro.
3. Kunoza guhangana nikirere cya minisiteri. Ifu ya freeze-thaw irwanya ifu ya latx nigikoresho cya termoplastique gifite imiterere ihindagurika, gishobora gutuma minisiteri ishobora guhangana nimpinduka ziva hanze mubukonje nubushyuhe, bikarinda neza minisiteri guturika kubera ihindagurika ryubushyuhe.
4. Kunoza imbaraga zoroshye za minisiteri. Polimeri na sima slurry bigira inyungu zuzuzanya. Iyo ibice biturutse ku mbaraga zo hanze, polymer irashobora kuzenguruka ibice kandi ikabuza kwaguka kwayo, bityo bikazamura ubukana bwavunitse ndetse nubumuga bwa minisiteri.
