Nigute ushobora kunoza ubwubatsi bwa selile ku rukuta rwo hejuru rwizuba

Kugeza ubu, iri hafi kwinjira mu cyi, kandi ubushyuhe buri hejuru cyane cyane mu karere ka majyaruguru.Ubushyuhe buri hejuru kandi umwuka wumye.Ubushyuhe bwo hejuru bwurukuta bushobora kugera kuri 60 ° C.Bitewe n'ubushyuhe, selile ikunze kugira ibibazo nko kubaka nabi no gukuraho ifu mugihe cyo kubaka.Impamvu nyamukuru ni uko bitewe nubushyuhe bwo hejuru bwurukuta, kubika amazi ya putty ntabwo ari byiza, bityo amazi yo muri putty ahita yinjizwa vuba cyangwa agashiramo umwuka kurukuta, kugirango ibishishwa bidashobora gutwikirwa inshuro nyinshi no gushushanya.Kugaragara no gukuramo biragaragara.Nigute ushobora kunoza amazi yo kubika ifu yinyuma yurukuta rwimbere rufite uburyo bukurikira:

1. Ongera umubare wa selile ya ether

Ether ya selile ifite amazi meza, ariko imikorere yo gufata amazi ntabwo yiyongera nyuma yumubare runaka wa selile ya selile.Muri icyo gihe, kwiyongera kwa selile byongera ubwiza bwa putty kandi kubaka ntibyoroshye.Mubyongeyeho, ikiguzi cya putty kiriyongera.

2. Ongera umubare wa lignocellulose

Lignocellulose ifite ingaruka zimwe zo gufata amazi.Kwiyongera kwa fibre yibiti byongera ubushobozi bwo gufata amazi yibikoresho, bigatuma sisitemu yibikoresho bigenda neza, kandi birashobora kunoza imikorere icyarimwe, ariko ihame ryo gufata amazi ya lignocellulose ritandukanye na selile.Ifite ibiranga kwinjiza umusatsi..Fungura igihe, ntabwo byoroshye gucamo.Nyamara, kubera ko umubyimba wa putty kurukuta rwinyuma ari muto cyane, ubunini bwa buri gipfunyika ni 0.5-1mm gusa.Iyo ubushyuhe bwubuso bwurwego rwibanze hamwe nubushyuhe bwikirere buri hejuru cyane, imikorere yo kugumana amazi ntigaragara, kandi imikorere isubirwamo inshuro nyinshi ni impuzandengo.

3. Ongera umubare wa polymer

Ku rukuta rufite ibishishwa byoroheje, umwuka wumye hamwe nubushyuhe bwo hejuru, kongera ubwinshi bwa polymer nimwe muburyo bwiza bwo gukora putty inshuro nyinshi zo gusiba, ariko igiciro cyifu ya redxersible latx iri hejuru cyane, umubare munini uziyongera cyane igiciro cya putty.Irashobora kandi kugira uruhare runini wongeyeho ifu ya alcool ya polyvinyl nkeya, ariko ubwiza bwifu ya polyvinyl alcool ni nini cyane, ibyo bizagira ingaruka kumikorere, kandi umutungo wumucanga wa putty ntabwo ari mwiza..

4. Ongeramo amavuta yo kwisiga

Binyuze mu kizamini, bifatwa ko ari byiza guhitamo kongeramo amavuta menshi cyane kurukuta rwinyuma rwashyizwe mubidukikije byubushyuhe bwinshi mu cyi.Amavuta yo kwisiga ni uruganda rwa polymer, kandi amavuta ya rheologiya agamije ahanini kunoza imikorere yubwubatsi muri sisitemu ishingiye kuri sima.Fungura igihe kandi imikorere ihamye.Yongera imikorere kandi ikarwanya imbaraga za minisiteri, plaster, renders, plasta na adheshes kandi ikarinda gusenya sima yo kwishyiriraho.Impamvu yo gufata amazi ni uko hari umubare munini wamatsinda ya hydrophilique ikora kumurongo wa molekile.Mugihe cyo gusiba no gutwikisha inshuro nyinshi, ntibizabura amazi, bifite imikorere idasanzwe yo gufata amazi, kandi bifite umubyimba na thixotropy icyarimwe, bigatuma ubwubatsi bworoha kandi bushobora gusimbuza selile, ariko igiciro cyacyo ni ether ya selile gusa, kandi igipimo cyacyo ni 0.1-0.2%., ni ibikoresho bihenze cyane, niba bikoreshejwe hamwe na selile ya ether, lignocellulose, hamwe nifu ya redxersible powder, ingaruka zizaba nziza.
