Cellulose inoshandiswa zvakanyanya mumafuta, mishonga, kugadzira mapepa, zvizoro, zvinhu zvekuvaka, nezvimwewo. Inoshandiswa zvakasiyana-siyana, uye mashandisirwo akasiyana ane zvinodiwa zvakasiyana pakushanda kwezvigadzirwa zve cellulose.
Chinyorwa chino chinonyanya kutaura nezvekushandiswa uye nzira yekuziva mhando yeHPMC (hydroxypropyl methylcellulose ether), rudzi rwecellulose runowanzoshandiswa muupfu hweputty hwakajairika.
HPMC inoshandisa donje rakanatswa sechigadzirwa chikuru. Inoshanda zvakanaka, mutengo wakakwira uye inodzivirira alkali zvakanaka. Yakakodzera putty yakajairika isingapindi mvura uye polymer mortar yakagadzirwa nesimende, lime calcium nezvimwe zvinhu zvine alkaline yakasimba. Huremu hwe viscosity ndeye 40,000-200000S.
Idzi ndidzo nzira dzakasiyana siyana dzekuedza mhando yehydroxypropyl methylcellulose dzakapfupikiswa naXiaobian. Uyai mudzidze neXiaobian~
1. Kuchena:
Ehe, chinhu chikuru pakusarudza mhando yehydroxypropyl methylcellulose hachifanirwe kunge chiri kuchena chete. Vamwe vagadziri vanozowedzera zvinhu zvinochenesa mukugadzirwa, muchiitiko ichi, mhando haigone kutongwa, asi kuchena kwehydroxypropyl methylcellulose yemhando yepamusoro kwakanaka chaizvo.
2. Kunaka:
Hydroxypropyl methylcellulose inowanzova nehupamhi hwemamesh makumi masere, mesh zana uye mesh zana nemakumi maviri. Kupfava kwezvikamu izvi kwakanaka kwazvo, uye kunyunguduka uye kuchengetwa kwemvura zvakanakawo. Iyi ihydroxypropyl methylcellulose yemhando yepamusoro.
3. Kutumira chiedza:
Isa hydroxypropyl methylcellulose mumvura woinyungudutsa mumvura kwenguva yakati kuti utarise kunaka kwayo uye kujeka kwayo. Kana gel yagadzirwa, tarisa kuti chiedza chayo chinofambiswa sei, chiedza chinofambiswa sei, uye kuchena kwayo kunowedzera.
4. Simba guru remhepo:
Kana simba remagetsi rakakura, zviri nani, nekuti simba remagetsi rakanyanya kurema, huwandu hwehydroxypropyl methyl huri mairi, ndiko kuti kuchengetedza mvura kuri nani.
