Cellulose ether ninyongera nyamukuru ya gypsumu yumucyo, igira uruhare runini muri gypsumu yoroheje.Uburenganzira ntabwo bworoshye guhomeka shingiro ryibicuruzwa bya selile ya HPMC, birashobora kwinjira vuba muburyo bwibicuruzwa byose bya gypsumu kandi ntibishobora kubyara cluster, ububobere bwo guhomesha gypsumu nyuma yo gukira nta ngaruka mbi, kugirango harebwe imikorere yo guhumeka ya gypsumu. , kudindiza ibikorwa ariko ntibigire ingaruka kuri kristu ya gypsumu yarakuze, hamwe nimbaraga zikonje zitose kugirango habeho ubushobozi bwo guhuza ibintu, hejuru yifatizo Kunoza cyane imikorere yubwubatsi bwibicuruzwa bya gypsumu, bigatuma byoroha gukwirakwizwa nta kwizirika ku bikoresho.
Nkuko mwese mubizi, mumyaka yashize, hamwe niterambere ryigihugu no guhindura politiki, iterambere ryibikoresho byubaka ibidukikije bibungabunga ibidukikije byahindutse ahantu hashyushye, kuko ibikoresho byo guhomesha mu nzu ibikoresho bishya, gypsumu yo guhomesha bigenda bigaragara cyane, gypsumu ni gusimbuza isima ya sima yibikoresho bishya bizigama ingufu, kurengera ibidukikije, ubukungu, byombi imbaraga za sima, kandi ugereranije na sima kurengera ibidukikije bifite ubuzima bwiza, biramba, imbaraga zifatika nini, ntabwo byoroshye kubifu, ntibimenagura, ntabwo ari ubusa ingoma, kudaterera ifu nibindi byiza, byoroshye gukoresha, kuzigama ikiguzi, gypsumu yoroheje ya plaster ishingiye cyane cyane kubaka ifu ya pompe nkibikoresho byingenzi, kumurika amashanyarazi ya perlite cyangwa ibirahuri nkibiterane, ongeramo ibikoresho bitandukanye bya plasta.
Cellulose ether Ifite ibyiza bikurikira:
Ubwa mbere, hindura ubushuhe bwikirere, mugihe ubuhehere bwo hanze buri hejuru yubushuhe bujyanye na plaster, kubera ko umuvuduko wumuyaga wo hanze urenze umuvuduko wumwuka wumwuka wacyo, utezimbere imikorere yimbere yo kwinjiza amazi, kugirango bidindiza izamuka ryamazi ubuhehere;Iyo ubuhehere bwo hanze buri munsi yubushuhe bukwiranye na gypsumu ihomye, umuvuduko wumwuka wumuyaga uri munsi yumuvuduko wumwuka wumuyaga, bigatuma umwuka wa molekile wimbere uhinduka.Kubwibyo, irashobora kugira uruhare rwo guhindura no kugenzura ubuhehere.
Icya kabiri, gufata neza flame.Uburemere bwa molekuline ya dihydrous gypsum ni 172, naho uburemere bwa molekile bwamazi ni 18. Iyo inzu ya 100m2 ihuye numuriro, iyo ubushyuhe bugeze kuri 110 ℃ cyangwa hejuru yayo, gypsumu ya dihydrous izahita irekura amazi ya kirisiti muri gypsumu ya semhydrous hanyuma igahinduka. muri gypsumu ya anhydrous, ishobora kurekura 560 kg y'amazi.Amazi arashobora gukuramo ubushyuhe bwinshi mugikorwa cyo guhumeka.Irashobora gukumira neza izamuka ryihuse ryubushyuhe bwicyumba kandi bikongerera amahirwe yo guhunga.
Icya gatatu, kurengera ibidukikije.Gypsum nyuma yo kuvurwa itagira ingaruka, ntabwo irimo umwanda uhumanya, gukoresha ibikoresho bya gel organique, inyongeramusaruro nibicuruzwa byo kurengera ibidukikije, bikozwe muri gips ya pompa yoroheje ntibisohora formaldehyde nibindi bintu byangiza, kurengera ibidukikije bibisi, umutekano nibindi byizewe.
Icya kane, kubika ubushyuhe, kuzigama ingufu, kwinjiza amajwi, kurwanya ingaruka.Amashanyarazi yubushyuhe bwo guhomesha ni 0.17W / (MK), bityo rero ubushyuhe bwumuriro wa plaster ni 20% bya minisiteri isanzwe ya sima isanzwe, ifite ingaruka zimwe na zimwe zogukoresha ubushyuhe kandi zishobora kugabanya gukoresha ingufu zinyubako.Gutera gesso biri mubikorwa bya condense, imbere bitanga icyuho gito, kubera ko ibyo bishobora kongera umuvuduko wijwi, birashobora kubuza ingufu zijwi kongera gukora, birashobora guhindura ingufu zijwi mububasha bwubushyuhe, bikagira imikorere myiza yo kubika amajwi bityo.Bitewe nuburyo bubi nyuma yo kwegeranya, irashobora gukuramo neza ingufu zingaruka, ntabwo rero izacika kandi igwa mugihe ikorewe ingaruka.
Gutera gypsumu hamwe na selulose ether ahanini ifite ibintu bikurikira:
1, ubwubatsi buhebuje: gusiba byoroshye, byoroshye, birashobora kuba ibumba, hamwe na plastike.
2, kunoza igipimo cya plaster mortar: ugereranije na ether isa na selile, igipimo cyo kwiyongera cyiyongereye cyane.
3, ibikorwa byiza birwanya anti-droop: igicucu cyinshi gisakaye ubwubatsi bumwe ntibutemba kumanikwa, inshuro zirenze ebyiri (zirenga 3cm) gusiba ntibitemba, plastike nziza.
4, igipimo cyiza cyo gufata amazi: kongerera igihe cyo gukora gypsumu, kunoza imiterere yikirere cya gypsumu, kongera imbaraga zihuza za gypsum na base, imikorere myiza yo guhuza amazi, kugabanya ivu ryubutaka.
5.
6, ikibanza cyo gusaba hamwe nubunini: urumuri rwo hasi rwa plaster gypsum, rusabwa dosiye 0.18% - 0.25%.
Gutera gypsumu hamwe na selile ya selile ikozwe mu ipamba ryiza cyane itunganijwe na etherification reaction, non-ionic selulose ether, imiterere yumubiri itajegajega, ntabwo izatanga imiti yimiti hamwe nibindi bikoresho bibisi kandi ikabyara ibintu byangiza, bitangiza ibidukikije, nta ngaruka kubuzima bwabantu, mu guhomesha gypsumu nubwoko bwinyongera bwokuzigama ingufu zicyatsi, KIMA yamye ari igitekerezo cyo kurengera ibidukikije no kubungabunga ingufu mubicuruzwa n’imicungire y’isosiyete, dushyigikira iterambere rirambye, mu rwego rwo guhamagarira igihugu, imisozi yatsi ni zahabu na feza imisozi, KIMA izakoresha ibicuruzwa byiza bya selulose ether kugirango ifashe isi gukora ibidukikije byangiza ibidukikije ibikoresho byo guhomeka murugo.
