Hpmc kuri gypsim plaster?

HPMC, izina ryuzuye ni hydroxypropyl methyl selile, ni selile itari ionic. Byakoreshejwe cyane mubikoresho byubaka, cyane cyane muri Gypsum plaster. HPMC ifite ibintu byinshi byiza, bikaba byinshi byongera kubikoresho byo kubaka nka Gypsum plaster.

Ibintu by'ibanze bya HPMC
Ingaruka nziza: HPMC ifite ingaruka nziza yijimye, ishobora kongera ubudakemu no gutsinda kuri gypsim plaster no kunoza imikorere yacyo.
Ifungwa ry'amazi: HPMC irashobora kunoza ubushake bwo kugumana mu mazi bya plaster, irinde amazi guhumeka vuba mugihe cyo kubaka, kandi tukamenya ko ari ubuhe buryo buhagije mugihe cyo kumisha, no kwirinda gucikamo.
Ingaruka yo gusiga: Bitewe n'ingaruka za HPMC, Gypsum Plaster yoroshye gukwirakwira no koroshya mugihe cyubwubatsi, kunoza imikorere yubwubatsi.
Adhesion: HPMC irashobora kuzamura uburozi hagati ya gypsum plaster na sustrate, kwemeza ko ahist ya plaster kugirango arengane nkinkike cyangwa agarura.
Guhagarara: HPMC ifite umutekano mwiza, irashobora gukomeza imikorere yacyo idahindutse mubidukikije bitandukanye, kandi ntabwo byoroshye ingaruka kumiterere yo hanze nkubushyuhe nubushuhe.

Gusaba HPMC muri Gypsum plaster
Ongeraho HPMC kuri Gypsum plaster ishusho irashobora kunoza imikorere yacyo no kubaka imitungo yanyuma. By'umwihariko:

Gutezimbere imikorere yubwubatsi: Gypsum Plaster yongeyeho hamwe na HPMC ifite amazi meza n'amazi, kubara byoroshye, kandi birakwiriye cyane cyane gupakira no gushyira mu gaciro.
Kunoza ubuzima bwiza: Bitewe no gusiga amavuta no kugumana amazi ya HPMC, ubuso bwa plaster yoroshye kandi byoroshye nyuma yo gukama, kugabanya ibituba n'ibiti.
Yongerewe Ashesion: HPMC itezimbere ubumwe hagati ya Gypsum Plaster hamwe na substrate zitandukanye, iremeza ko ushikamye urwego kandi wirinde kumena.
Igihe cyagutse: Kubera imitungo igamana amazi ya HPMC, Plaster ya Gypsum ifite igihe kirekire gifasha mugihe cyo kubaka, kwemerera abakozi bubaka igihe kinini cyo guhindura no gutegura, kugabanya imyanda yibintu.

Ingamba zo gukoresha hpmc
Nubwo HPMC ifite ibyiza byinshi, hari ibintu bimwe ugomba kwitondera mugihe cyo gukoreshwa:

Amafaranga yinyongera: Umubare winyongera wa HPMC igomba kugenwa hakurikijwe ibisabwa hamwe nibisabwa. Muri rusange, HPMC nyinshi izatera guhuza gypsum plaster kuba ndende cyane, idakwiriye kubaka; Mugihe wongeyeho bike, ingaruka zifuzwa ntizishobora kugerwaho.
Disigice imwe: Mugihe cyo gukora Scoster, HPMC igomba kubatatana cyane muburyo bwo kuvanga kugirango tumenye neza ko ari byiza rwose. Birasabwa gukoresha ibikoresho bivanga hamwe nikoranabuhanga kugirango ugere kuri make.
Guhuza n'izindi nguzanyo: HPMC igomba gukomeza guhuza neza nizindi nguzanyo muri Gypsum plaster kugirango wirinde imikoranire iri hagati yinyongera zishobora kugira ingaruka kumikorere ya nyuma. Mubyiciro bifatika, ubushakashatsi burakenewe kugirango hamenyekane formulaire nziza.

Imikorere y'ibidukikije ya HPMC
Nka selile itari ionic ether, HPMC ifite imikorere myiza y'ibidukikije. Ntabwo ari uburozi, ntacyo bitwaye, nta mico yangiza kandi ifite urugwiro. Byongeye kandi, HPMC ni bizima kandi ntabwo izatera umwanda mubidukikije mugihe cyo gukoresha. Nibintu bibisi no kubaka ibidukikije.

Nkikibazo gikomeye kuri Gypsum plaster, HPMC yakoreshejwe cyane mu nganda zubwubatsi kubera imitungo yayo myiza nko kubyimba, kugumana amazi, guhonyora no kuzamura. Gukoresha neza HPMC birashobora kunoza cyane imikorere yubwubatsi nubuziranenge bwanyuma bwa plaster, gutanga igisubizo cyiza cyo kubaka. Mu buryo bw'ejo hazaza, hamwe no guteza imbere ikoranabuhanga no kurushaho kwerekana ibyifuzo, HPMC yerekana ko yaziho ibyiza byayo mu bice byinshi.
