IHydroxyethyl methyl cellulose

IHydroxyethyl methyl cellulose (HEMC) yalungiswa ngokuzisa i-ethylene oxide endaweni ye-methyl cellulose (MC). Ukunyamezelwa kwayo ityuwa kwakungcono kunepolymer engafakwanga, kwaye iqondo lobushushu le-methyl hydroxyethyl cellulose laliphezulu kunelo methyl cellulose.

ⅠUkusebenza ngokubambisana

1. Inkangeleko: Umhlophe okanye umgubo omhlophe ofanayo, akukho magazini imatshini, ayinavumba kwaye ayinamkhwa

2. Ubushushu beGel (℃): 60-90

3. Umxholo wamanzi （Wt%）: ≤5.0

Umxholo we-Ash （Wt%）: ≤5.0

5.HP: 5.0-8.0

6. Ukunyaniseka: ≥80 Mesh

7.Viscosity osity mPa.s, 2% isisombululo samanzi, 20 ± 0.2 ℃）: 100000-20000

Ⅱ.Ukusebenza kobugcisa

1. Ukunyibilika: imodeli H kwi-HEMC inokupheliswa kumanzi abandayo kunye namanzi ashushu, ngelixa imodeli L inokunyibilika kuphela emanzini abandayo, ngelixa i-HEMC inyibilikiswa kwizinyibilikisi ezininzi eziphilayo. Umphezulu ophethwe yi-HEMC usasazeke emanzini abandayo kwaye awenzi buthanani. Nangona kunjalo, inokuchithwa ngokukhawuleza ngokulungisa ixabiso layo le-pH ukuya kwi-8-10

2. Uzinzo lwe-PH: Ixabiso le-pH kuluhlu lwe-2 ukuya ku-2 yokuboniswa koshintsho lincinci, ngaphaya koluhlu lokubonwa kwe-viscosity

3. I-HEMC ineempawu zokuqina, ukumiswa, ukusasazeka, ukunamathela, ukumiliselwa, ukwenziwa kwefilim kunye nokugcinwa kwamanzi, kunye namandla ayo okubamba amanzi anamandla kune-methylcellulose. Ukuzinza kwe-Visccious, ukuxhathisa i -ypew kunye nokusasazeka kubhetele kune-hydroxyethyl cellulose

Ⅲ. Ukusetyenziswa kunye nokulumkisa

I-HEMC isetyenziswa ngokubanzi kumalaji asekwe emanzini kwi-latex, ekwakhiweni nasekwenzeni izinto, kwi-inki yokuprinta, ekuqhubeni ioli, njl njl

Ⅳ. Iphakheji kunye nokugcinwa

1.Le mveliso ineliphepha ledatha yokhuseleko kunye nedatha yemvume yokuhamba ngokhuseleko

2.Le mveliso igcwele kwi-25 kg okwakhiwa kwephepha kunye nefilimu yeplastiki ebekwe kwifilimu

3.Gcina kwindawo eyomileyo, nikela ingqalelo kubungqina bokufuma
