Chii chinonyanya kushandiswa nehydroxypropyl methylcellulose?
——Mhinduro:HPMCinoshandiswa zvakanyanya muzvinhu zvekuvaka, machira ekuputira, maresini ekugadzira, zviumbwa zvedoro, mishonga, chikafu, machira, kurima, zvizoro, fodya nedzimwe nzvimbo. HPMC inogona kukamurwa kuita giredhi rekuvaka, giredhi rechikafu uye giredhi remishonga zvichienderana nechinangwa. Parizvino, zvigadzirwa zvakawanda zvemumba ndezve giredhi rekuvaka. Mugiredhi rekuvaka, putty powder inoshandiswa zvakanyanya, inenge 90% inoshandiswa putty powder, uye yasara inoshandiswa simende mortar neglue.
Nzira yekusiyanisa sei mhando yeHPMC zviri nyore uye nenzira intuitively?
——Mhinduro: (1) Kuchena: Kunyange zvazvo kuchena kusingakwanise kuona kana HPMC iri nyore kushandisa, uye kana mishonga yekuchenesa ikawedzerwa panguva yekugadzira, zvichakanganisa kunaka kwayo. Zvisinei, zvigadzirwa zvakawanda zvakanaka zvine kuchena kwakanaka. (2) Kuchena: Kuchena kweHPMC kunowanzova ne80 mesh uye 100 mesh, uye 120 mesh ishoma. HPMC yakawanda inogadzirwa muHebei ine 80 mesh. Kuchena kwakanyanya, kazhinji, ndiko kuri nani. (3) Kutapurirana kwechiedza: isa hydroxypropyl methylcellulose (HPMC) mumvura kuti igadzire colloid yakajeka, uye tarisa kutapurirana kwayo kwechiedza. Kutapurirana kwechiedza kwakakura, ndiko kuri nani, zvichiratidza kuti hapana zvinhu zvakawanda zvisinganyunguduke mairi. . Kupinda kwe vertical reactors kazhinji kwakanaka, uye kwe horizontal reactors kwakaipa, asi hazvirevi kuti mhando ye vertical reactors iri nani pane ye horizontal reactors, uye mhando yechigadzirwa inotsanangurwa nezvinhu zvakawanda. (4) Specific gravity: Kukura kwe specific gravity, kurema kwakanyanya kunaka. Hunhu hwacho hwakakura, kazhinji nekuti huwandu hwehydroxypropyl group hurimo hwakakwira, uye huwandu hwehydroxypropyl group hwakakwira, kuchengetedza mvura kuri nani. (5) Kupisa: Tora chikamu chidiki chemuenzaniso wochibatidza nemoto, uye zvasara zvichena zvinova dota. Kana zvinhu zvichena zvakawanda, kunaka kwazvo kunowedzera, uye hapana zvasara muzvinhu zvakachena.
Mutengo wehydroxypropyl methylcellulose unoita sei?
—–Mhinduro; mutengo wehydroxypropylmethyl unoenderana nekuchena kwayo uye huwandu hwedota. Kuchena kwacho kwakanyanya, huwandu hwedota hushoma, mutengo wacho wakakwira. Zvikasadaro, kuchena kwacho kwakaderera, huwandu hwedota hunowedzera, mutengo wacho wakaderera. Toni kusvika 17,000 yuan patani. 17,000 yuan chigadzirwa chakachena chisina tsvina. Kana mutengo weyuniti wakakwira kupfuura 17,000 yuan, purofiti yemugadziri yakawedzera. Zviri nyore kuona kana mhando yacho yakanaka kana kuti yakaipa zvichienderana nehuwandu hwedota riri muhydroxypropyl methylcellulose.
Chii chinonzi viscosity yehydroxypropyl methylcellulose yakakodzera putty powder nemortar?
—– Mhinduro; putty powder inowanzova 100,000 yuan, uye chinodiwa chemortar chakakwira, uye inoda 150,000 yuan kuti ive nyore kushandisa. Uyezve, basa rakakosha rehydroxypropyl methylcelluloseinochengetedza mvura, ichiteverwa nekukora. Muupfu hweputty, chero bedzi inochengetedza mvura zvakanaka uye viscosity yakaderera (70,000-80,000), zvinogonekawo. Ehe, viscosity iri pasi pe100,000 yakakwira, uye kuchengetwa kwemvura kuri nani. Kana viscosity ikadarika 100,000, viscosity ine simba pakuchengetedza mvura. Kukanganisa hakuna kunaka.
