Nyore yekuzivikanwa nzira yehydroxypropyl methylcellulose

Cellulose inoshandiswa zvakanyanya mu petrochemical, mushonga, papermaking, cosmetics, zvinhu zvekuvaka, etc. Icho chinowedzera zvakasiyana-siyana, uye kushandiswa kwakasiyana kune zvakasiyana-siyana zvekushanda kwezvigadzirwa zve cellulose.

Ichi chinyorwa chinonyanya kusuma mashandisirwo uye nzira yekuziva yemhando yeHPMC (hydroxypropyl methylcellulose ether), mhando ye cellulose inowanzoshandiswa mune yakajairwa putty poda.

HPMC inoshandisa donje rakacheneswa seyakanyanya mbishi zvinhu. Iyo ine kuita kwakanaka, mutengo wakakwira uye yakanaka alkali kuramba. Yakakodzera kune yakajairwa mvura-inodzivirira putty uye polymer dhaka yakagadzirwa nesamende, lime calcium uye zvimwe zvakasimba alkaline zvinhu. Iyo viscosity range ndeye 40,000-200000S.

Idzi dzinotevera nzira dzinoverengeka dzekuyedza mhando yehydroxypropyl methylcellulose yakapfupikiswa neXiaobian kwauri. Huya udzidze naXiaobian~

1. Kuchena:

Ehe, chinhu chinogadzirisa pakuona mhando yehydroxypropyl methylcellulose haigone kungova chena. Vamwe vagadziri vanozowedzera maajenti ekuchena mukugadzira, mune iyi nyaya, mhando haigone kutongwa, asi kuchena kwemhando yepamusoro hydroxypropyl methylcellulose yakanaka chaizvo.

2. Fineness:

Hydroxypropyl methylcellulose kazhinji ine hunyoro hwe80 mesh, 100 mesh uye 120 mesh. Iko kunaka kwezvimedu zvakanaka kwazvo, uye kunyungudika uye kuchengetwa kwemvura zvakare kwakanaka. Iyi imhando yepamusoro hydroxypropyl methylcellulose.

3. Chiedza chekufambisa:

Isa hydroxypropyl methylcellulose mumvura uye inyunguduse mumvura kwenguva yakati kuti utarise viscosity uye pachena. Mushure mekunge gel yagadzirwa, tarisa mwenje wayo wekufambisa, zviri nani iyo mwenje transmittance, iyo inokwirisa iyo insoluble nyaya uye kuchena.

4. Chaiyo giravhiti:

Iyo yakakura iyo chaiyo giravhiti, zviri nani, nekuti iyo inorema iyo chaiyo giravhiti, iyo yakakwirira yemukati yehydroxypropyl methyl mairi, zviri nani kuchengetedza mvura.
