Haba hari amakuru yubushakashatsi ashobora kwerekana ingaruka zihariye za HPMC kumitungo ya minisiteri?

Ibikoresho byubushyuhe nubukanishi: ubushakashatsi
Irerekana ko HPMC ishobora kunoza imiterere yubushyuhe nubukanishi bwa plaster. Mu kongeramo imbaraga zitandukanye za HPMC (0.015%, 0.030%, 0.045%, na 0.060%), abashakashatsi basanze ibikoresho byoroheje bishobora kubyara umusaruro ugabanukaho ibiro 11,76% kubera ubukana bwinshi buterwa na HPMC. Iyi poritike nini ifasha mukwirinda ubushyuhe, kugabanya ibikoresho byamashanyarazi kugera kuri 30% mugihe hagumijwe ubushyuhe buhoraho bwa 49 W mugihe uhuye nubushyuhe bumwe. Kurwanya ihererekanyabubasha binyuze mu kibaho byari bitandukanye n’ubwinshi bwa HPMC yongeweho, hamwe n’ibindi byinshi byongewemo bigatuma 32,6% byiyongera ku kurwanya ubushyuhe ugereranije n’uruvange ruvanze.

Kubika amazi, gukora n'imbaraga: ubundi bushakashatsi
Byagaragaye ko HPMC ishobora guteza imbere cyane gufata neza amazi, guhuriza hamwe no guhangana na minisiteri, kandi igateza imbere cyane imbaraga zingutu nimbaraga za minisiteri. Muri icyo gihe, HPMC irashobora kubuza neza ishingwa rya plastike muri minisiteri no kugabanya igipimo cya plastike. Kugumana amazi ya minisiteri byiyongera uko ubwiza bwa HPMC bwiyongera. Iyo ubwiza bwa HPMC burenze 40000 mPa · s, kubika amazi ntibikiyongera cyane.

Uburyo bwo gupima Viscosity: Iyo wiga uburyo bwo gupima viscosity hydroxypropyl methylcellulose
, wasanze HPMC ifite ikwirakwizwa ryiza, emulisile, kubyimba, guhuza, gufata amazi hamwe no kubika kole. Iyi mitungo ituma HPMC ikoreshwa cyane mubikorwa byubwubatsi.

Ijwi rihamye: Ubushakashatsi ku ngaruka za dosiye ya HPMC kumubyigano wambere wa Portland cement-aluminate cement-gypsum ternary composite yo kwishyiriraho minisiteri
Irerekana ko HPMC igira ingaruka zikomeye kumikorere ya minisiteri yo kwipima. Nyuma yo kwinjizamo HPMC, imikorere ya minisiteri yo kwisuzumisha nko kuva amaraso no gutandukanya amacakubiri iratera imbere cyane. Nyamara, ibipimo birenze urugero ntabwo bifasha gutembera kwa minisiteri yo kwipimisha. Igipimo cyiza ni 0.025% ~ 0.05%. Muri icyo gihe, uko ibirimo HPMC byiyongera, imbaraga zo guhonyora hamwe nimbaraga zihindagurika zo kwipima minisiteri zigabanuka kurwego rutandukanye.

Ingaruka ku mbaraga zumubiri wicyatsi kibisi: ubushakashatsi
Ingaruka yibintu bitandukanye bya HPMC kumbaraga zingirakamaro zumubiri wicyatsi kibisi ceramic, kandi byagaragaye ko imbaraga za flexural zabanje kwiyongera hanyuma zigabanuka niyongera ryibirimo HPMC. Iyo HPMC yongeyeho yari 25%, imbaraga z'umubiri wicyatsi nizo zari hejuru kuri 7.5 MPa.

Kuma kuvanga imikorere ya minisiteri: ubushakashatsi
Byagaragaye ko umubare utandukanye hamwe nubukonje bwa HPMC bigira ingaruka zikomeye kumikorere yakazi hamwe nubukanishi bwa minisiteri yumye ivanze. HPMC ifite ubushobozi bwo kugumana amazi no kubyimba. Iyo dosiye irenze 0,6%, amazi ya minisiteri aragabanuka; iyo dosiye ari 0.4%, igipimo cyo gufata amazi ya minisiteri gishobora kugera 100%. Ariko, HPMC igabanya cyane imbaraga, kugeza kuri 75%.

Ingaruka kuri sima-itunganijwe neza-yuzuye ubukonje bukonje buvanze: ubushakashatsi
Byagaragaye ko HPMC izagabanya imbaraga zoguhindura no gukomeretsa ingero za sima nyuma ya hydrata ya sima kubera ingaruka zangiza ikirere. Nyamara, sima iyobowe no gukwirakwiza HPMC yashonga mumazi. Ugereranije na sima iyobowe mbere hanyuma ikavangwa na HPMC, imbaraga za flexural na compressive zintangarugero za sima ziyongera.

Aya makuru yubushakashatsi hamwe nubushakashatsi bwakozwe yerekana ko HPMC igira ingaruka nziza mugutezimbere amazi ya minisiteri, kunoza imikorere, no kunoza imikorere yubushyuhe, ariko birashobora no kugira ingaruka kumbaraga nubunini bwa minisiteri. Kubwibyo, mubikorwa bifatika, ibipimo nibisobanuro bya HPMC bigomba gutoranywa muburyo bushingiye kubisabwa byubwubatsi hamwe nibidukikije kugirango bigerweho neza.
