HydroxyPropyl Methylcellse (HPMC) ni polymer ya polymer ikoreshwa cyane mubwubatsi, ubuvuzi, ibiryo nibindi bice. Mu nganda za sima, Slowl®hpmc ikunze gukoreshwa nkinyongera kugirango inoze cyane imikorere ya sima, no kuzamura gahunda, gufatanya no gukomera kwanyuma.
1. Imiterere y'ibanze hamwe nuburyo bwo gukora bwa HPMC
HPMC ni ibintu byimiti byabonetse muguhindura ibigari binyuze kuri roholation, hydroxy oplekile Imiterere yayo ikubiyemo hydrophilic nitsinda ryimikino myinshi, rituma rigira uruhare runini muri sisitemu ya sima. HPMC igira uruhare rukurikira muri sima:
Ingaruka mbi
HPMC ifite ingaruka zikomeye kandi zirashobora kunoza ubukwe bwa sima ryanditse, bigatuma sima rivanze cyane mugihe cyo kuvanga no kwirinda gushira cyangwa kwiringira. Ibi ni ngombwa mu kuzamura amazi no gutuza kwa sima, cyane cyane mu bikoresho bifatika cyangwa ibindi bikoresho bisabwa, byemeza ko byuzuza mold neza kandi bifite ubucucike buhebuje kandi bufite ubucucike bwinshi.
Gutezimbere
HPMC irashobora kugenzura neza igipimo cyo guhumeka kwamazi muri sima yakatiye no gutinza igihe cyambere cya sima. Cyane cyane mubushyuhe bwinshi cyangwa ibidukikije byumye, birashobora kugumana ubuvuzi bwa sima, no gukumira gukama imburagihe, bityo bikabangamira imikorere yubwubatsi. Kugumana amazi ni umutungo w'ingenzi mu mikorere yo kubaka ibikoresho bya sima kandi birashobora kubuza neza ishyirwaho ry'imigabane.
Kunoza Adhesion no kuzamura amazi
Ibindi biyongera bya chimique akenshi byongerwa muri sima, nka polymer, imiberehone, nibindi, bishobora kugira ingaruka kumatwi ya sima. HPMC irashobora kongera imbaraga zo guhuza sima, gukora plastike nyinshi n'amazi, bityo bigatuma imikorere yubwubatsi. Byongeye kandi, HPMC irashobora kandi kuzamura uburori hagati ya sima nibindi bikoresho byubaka (nkumusenyi na kaburimbo) no kugabanya ibintu.
Kunoza Kurwanya Crack
Kubera ko Slowntlp®hpmc irashobora kunoza imbaraga za sima no gutinza inzira yo gukumira, irashobora kandi kunoza neza ibikoresho byo kurwanya sima. Cyane cyane mugihe cyambere mugihe imbaraga za sima zitagera kurwego ruhagije, ibikoresho bya sima bikunze gushingwa. Ukoresheje HPMC, igipimo cya sima gishobora gutinda no gushiraho byatewe nigihombo cyamazi byihuse birashobora kugabanuka.
2. Ingaruka za HPMC muri porogaramu ya sima
Kunoza ibikorwa bya sima
Ingaruka zijimye za HPMC ituma sima yakamba neza. Ku bwoko butandukanye bwa sima (nk'ibyuma bisanzwe by'ibice bya Porceland, sima yuzuye, n'ibindi), HPMC irashobora kunoza amazi yo gutandukana no koroshya gusuka no kubumba mugihe cyo kubaka. Byongeye kandi, HPMC irashobora gukora sima Paste ihamye mugihe cyubatswe, kugabanya ibintu bihuje ikirere, kandi utezimbere ubuziranenge bwubwubatsi.
Kunoza imbaraga za sima
Ongeraho HPMC irashobora kunoza imikorere ya sima kurwego runaka. Ihindura ikwirakwizwa ry'amazi muri sima, iteza imbere hydration imwe ihuye n'imiterere ya sima, bityo ikongerera imbaraga zanyuma za sima. Mubyiciro bifatika, byongeramo amafaranga akwiye ya HPMC irashobora guteza imbere isura yambere ya sima kandi itezimbere imbaraga zigenda zikandagirana, zoroheje.
Iterambere
Ongeraho HPMC ifasha kunoza kuramba. Cyane cyane iyo sima ihuye n'ibidukikije (nka aside, alkali, saline, HPMC irashobora kongera kurwanya imiti no kurwanya sima, kugira ngo bigaragaze ubuzima bwa serivisi. Byongeye kandi, HPMC irashobora kugabanya ubuswa bwa sima ivanze kandi yongera ubucucike bwa sima, bityo bikagabanya igipimo cyangirika mubidukikije bikaze.
Kunoza Imiterere y'ibidukikije
Mubihe bikabije, imikorere ya sima ikunze kwibasirwa nimpinduka mubushyuhe nubushuhe. HPMC irashobora gutinza igihe cyo gushiraho sima yacitse kandi igabanye ibibazo biterwa no gukama byihuse cyangwa hydtion nyinshi. Kubwibyo, birakwiriye cyane cyane kubidukikije hamwe nubushyuhe bwo hejuru, ubushyuhe buke nubushuhe bunini.
3. Gukoresha neza HPMC
Nubwo ikoreshwa rya HPMC muri sima rishobora kunoza imikorere yacyo, ikoreshwa ryaryo rigomba kwitonda, cyane cyane mumafaranga yongeweho. Kongeraho cyane HPMC irashobora gutera vicosiya ya sima yakatiye cyane, bikavamo ingorane zidashira cyangwa kubaka. Mubisanzwe, ingano ya HPMC yongeyeho igomba kugenzurwa hagati ya 0.1% na 0.5% ya sima, hamwe nagaciro gakenewe guhindurwa hakurikijwe ubwoko bwa sima, gusaba nibidukikije.
Inkomoko zitandukanye, Ibisobanuro hamwe na dogere yaHpmc irashobora kandi kugira ingaruka zitandukanye kumashanyarazi. Kubwibyo, mugihe uhitamo HPMC, ibintu nkuburemere bwa molekile, sydroxyPropyl na methylatiopropyle na methylatiolation gahunda bigomba gufatwa nkibisanzwe kugirango ubone impinduka nziza. Ingaruka.
Nk'imyifatire y'ingenzi, Slowlthpmc itezimbere cyane ibikorwa, imbaraga, kuramba no guhuza na sima no guhuza na cickening, kunoza ingufu z'amazi no guteza imbere ubupfura. Its wide application in the cement industry not only improves the overall performance of cement, but also provides strong support for the research and development of new cement products such as high-performance concrete and environmentally friendly building materials. Nkuko imishinga yo kubaka ikomeje kongera ibyo bakeneye kubikorwa byibintu, HPMC ifite ibyifuzo byagutse mu nganda za sima kandi bizakomeza kuba sima ihinduranya na cemedi.
