Ni ubuhe buryo bukwiye bwo gupima hydroxypropyl methylcellulose (HPMC)?
Ifu ya putty muri rusange ni yuan 100.000, kandi ibisabwa kuri sitrove ni byinshi, kandi yuan 150.000 birakenewe kugira ngo byorohe kuyikoresha. Byongeye kandi, akazi k'ingenzi ka HPMC ni ukubika amazi, hagakurikiraho gucumba. Mu ifu ya putty, igihe cyose amazi abika neza kandi ubukana buri hasi (70.000-80.000), birashoboka. Birumvikana ko uko ubukana bwiyongera, ni ko amazi abika neza. Iyo ubukana burenze 100.000, ubukana buzagira ingaruka ku bukana bw'amazi. Ntabwo bikiri byinshi.
Ni ubuhe buryo bwo gushonga bwa hydroxypropyl methylcellulose (HPMC)?
(1) Ubuziranenge: Nubwo Baidu idashobora kumenya niba HPMC yoroshye kuyikoresha, kandi niba hongewemo ibikoresho byo kuyungurura mu gihe cyo kuyitunganya, ubwiza bwayo buzahinduka. Ariko, ibicuruzwa byinshi byiza bifite ubuziranenge bwiza.
(2) Ubutonyanga: Ubutonyanga bwa HPMC muri rusange bufite mesh 80 na mesh 100, naho mesh 120 ni nkeya. HPMC nyinshi ikorerwa muri Hebei ni mesh 80. Uko ubutonyanga burushaho kuba bwiza, muri rusange, niko biba byiza.
(3) Kohereza urumuri: shyira hydroxypropyl methylcellulose (HPMC) mu mazi kugira ngo habeho colloid ibonerana, hanyuma urebe uko urumuri rwayo rugenda rurushaho kumera. Uko urumuri rugenda rurushaho kumera ni ko rugenda rumera neza, bigaragaza ko hari ibintu bike bidashonga muri yo. . Ihererekanya ry’imashini zihagaze muri rusange ni ryiza, naho iry’imashini zihagaze mu buryo butambitse ni ribi cyane, ariko ntibivuze ko ubwiza bw’imashini zihagaze ari bwiza kurusha iry’imashini zihagaze, kandi ubwiza bw’umusaruro bugenwa n’ibintu byinshi. (4) Uburemere bwihariye: Uko uburemere bwihariye bugenda burushaho kuba bwinshi, ni ko uburemere burushaho kuba bwiza. Uburemere ni bwinshi, muri rusange kubera ko ingano y’itsinda rya hydroxypropyl iri muri yo ari nyinshi, kandi ingano y’itsinda rya hydroxypropyl iri hejuru, amazi agumana neza.
Ni iyihe nshingano nyamukuru yo gukoresha HPMC mu ifu ya putty, kandi se bibaho mu buryo bwa shimi?
Mu ifu ya putty, HPMC igira uruhare rutatu mu gutuma amazi akomera, kuyabika no kuyashyiraho.
Ububyimbirwe: Selilulose ishobora gukongerwa kugira ngo ikomeze guhagarara neza kandi ikomeze kuba imwe hejuru no hasi, kandi irinde kugwa.
Kubika amazi: tuma ifu ya putty yumuka buhoro buhoro, kandi ufashe kalisiyumu y'ivu gukora iyo amazi arimo gukora.
Imiterere: Selulosi ifite ubushobozi bwo gusiga amavuta, bishobora gutuma ifu ya putty igira imiterere myiza. HPMC ntabwo igira uruhare mu bikorwa bya shimi, ahubwo igira uruhare rw'inyongera gusa. Kongera amazi ku ifu ya putty no kuyishyira ku rukuta ni imikorere ya shimi, kuko ibintu bishya bibaho. Iyo ukuye ifu ya putty ku rukuta ku rukuta, ukayisya ikameramo ifu, hanyuma ukongera kuyikoresha, ntabwo izakora kuko ibintu bishya (calcium carbonate) nabyo byakozwe.
Ibice by'ingenzi bigize ifu ya kalisiyumu y'ivu ni: uruvange rwa Ca(OH)2, CaO n'ingano nto ya CaCO3, CaO+H2O=Ca(OH)2 —Ca(OH)2+CO2=CaCO3↓+H2O kalisiyumu y'ivu mu mazi no mu mwuka Mu gihe CO2 ikora, kalisiyumu karubone irakorwa, mu gihe HPMC igumana amazi gusa, igafasha mu buryo bwiza bwa kalisiyumu y'ivu, kandi ntigira uruhare mu buryo ubwo aribwo bwose.
Isano iri hagati y’ubushyuhe n’ubushyuhe bya HPMC, ni iki kigomba kwitabwaho mu ikoreshwa ry’ibikoresho?
Ubushyuhe bwa HPMC bungana mu buryo bunyuranye n'ubushyuhe, ni ukuvuga ko ubushyuhe bwiyongera uko ubushyuhe bugabanuka. Ubushyuhe bw'ikintu dukunze kuvugaho buvuga ku bisubizo by'isuzuma ryacyo rya 2% by'amazi ku bushyuhe bwa dogere selisiyusi 20.
Mu bikorwa bifatika, ni ngombwa kumenya ko mu turere dufite itandukaniro rinini ry'ubushyuhe hagati y'impeshyi n'itumba, ni byiza gukoresha ubushyuhe buke mu gihe cy'itumba, ibyo bikaba byoroshye mu bwubatsi. Bitabaye ibyo, iyo ubushyuhe buri hasi, ubushyuhe bwa selulose buziyongera, kandi intoki zigakomera mu gihe cyo gukurura.
Uburemere buri hagati: 75000-100000 ikoreshwa cyane cyane mu guteka puti
Impamvu: amazi agumana neza
Ubushyuhe bwinshi: 150000-200000 ikoreshwa cyane cyane mu gushonga uduce duto twa polystyrene hamwe n'udupira duto twa vitrified microbead insulation.
Impamvu: ubushyuhe bwinshi, sima ntabwo byoroshye kugwa, iragwa, ibyo bigatuma imiterere yayo irushaho kuba myiza.
