Ikoreshwa rya hydroxypropyl methylcellulose, uburyo bwo gutandukanya ubwiza bwa HPMC mu buryo bworoshye kandi bwumvikana

Ni iyihe mikoreshereze nyamukuru ya hydroxypropyl methylcellulose?

——Igisubizo:HPMCikoreshwa cyane mu bikoresho by'ubwubatsi, irangi, resins zikoze mu byuma, ibumba, ubuvuzi, ibiribwa, imyenda, ubuhinzi, amavuta yo kwisiga, itabi n'izindi nganda. HPMC ishobora kugabanywamo urwego rw'ubwubatsi, urwego rw'ibiribwa n'urwego rw'imiti hakurikijwe icyo igamije. Kuri ubu, inyinshi mu bicuruzwa byo mu rugo ni urwego rw'ubwubatsi. Mu rwego rw'ubwubatsi, ifu ya putty ikoreshwa cyane, hafi 90% ikoreshwa mu ifu ya putty, naho isigaye ikoreshwa mu gukora sima na kole.

Ni gute watandukanya ubwiza bwa HPMC mu buryo bworoshye kandi bwumvikana?

——Igisubizo: (1) Ubweru: Nubwo umweru udashobora kumenya niba HPMC yoroshye gukoresha, kandi niba ibikoresho byo kuyungurura byongewemo mu gihe cyo kuyikora, bizagira ingaruka ku bwiza bwayo. Ariko, ibicuruzwa byinshi byiza bifite umweru mwiza. (2) Ubwiza: Ubwiza bwa HPMC muri rusange bufite mesh 80 na mesh 100, naho mesh 120 ni nkeya. HPMC nyinshi zikorerwa muri Hebei ni mesh 80. Uko ubube bwiza, muri rusange, ni ko biba byiza. (3) Kohereza urumuri: shyira hydroxypropyl methylcellulose (HPMC) mu mazi kugira ngo ukore colloid ibonerana, kandi urebe uko urumuri rutanga. Uko urumuri rutanga urumuri rwinshi, ni ko biba byiza, bigaragaza ko hari ibintu bidashonga byinshi. . Ihererekanya ry'imashini zihagaze muri rusange ni ryiza, naho imashini zitambitse zikaba mbi, ariko ntibivuze ko ubwiza bw'imashini zihagaze ari bwiza kuruta imashini zitambitse, kandi ubwiza bw'umusaruro bugenwa n'ibintu byinshi. (4) Uburemere bwihariye: Uko uburemere bwihariye buba bwinshi, ni ko uburemere burushaho kuba bwiza. Ubwinshi bw'ibipimo ni bwinshi, muri rusange kubera ko ibikubiye mu itsinda rya hydroxypropyl birimo ari byinshi, kandi ibikubiye mu itsinda rya hydroxypropyl biri byinshi, amazi agumana neza kurushaho. (5) Gutwika: Fata igice gito cy'icyitegererezo ugitwike umuriro, maze ibisigazwa by'umweru biba ivu. Uko ibintu by'umweru byinshi, ni ko ubwiza burushaho kuba bubi, kandi nta bisigazwa biba biri mu bintu byuzuye.

Igiciro cya hydroxypropyl methylcellulose ni ikihe?

—–Igisubizo; igiciro cya hydroxypropylmethyl giterwa n’ubuziranenge bwayo n’ingano yayo y’ivu. Uko ubuziranenge burushaho kuba bwinshi, ni ko igiciro kiba gito. Bitabaye ibyo, uko ubuziranenge bugabanuka, ni ko igiciro kiba gito. Toni igera kuri yuan 17.000 kuri toni. Yuan 17.000 ni ibicuruzwa bidafite umwanda hafi ya wose. Niba igiciro cy’iyuniti kiri hejuru ya yuan 17.000, inyungu y’uruganda iba yariyongereye. Biroroshye kureba niba ubwiza ari bwiza cyangwa bubi bitewe n’ingano y’ivu riri muri hydroxypropyl methylcellulose.

Ni ubuhe buryohe bwa hydroxypropyl methylcellulose bukwiriye ifu ya putty na mortier?

—–Igisubizo; ifu ya putty muri rusange ni yuan 100.000, kandi igikenewe kuri sitrove ni kinini, kandi ikenera yuan 150.000 kugira ngo yorohe kuyikoresha. Byongeye kandi, akazi k'ingenzi kahydroxypropyl methylcelluloseni ugufata amazi, hagakurikiraho ubugari. Mu ifu ya putty, igihe cyose amazi aguma neza kandi ubugari buri hasi (70.000-80.000), birashoboka. Birumvikana ko ubugari buri munsi ya 100.000 buba buri hejuru, kandi ubugari bw'amazi buba bwiza kurushaho. Iyo ubugari burenze 100.000, ubugari bugira ingaruka ku kubika amazi. Ingaruka si nziza cyane.
