Isizathu sokuba i-hydroxypropyl methylcellulose isetyenziswe ngokubanzi

IHydroxypropyl methylcellulose ngoku isetyenziswa kuzo zonke iinkalo zobomi. Loluphi uhlobo lwemathiriyeli ekrwada?

Ukususela kumbono womzimba, i-hydroxypropyl methylcellulose i-ether ye-cellulose engekho i-ionic, i-powder emhlophe, kwaye ayinayo incasa. Kushishino lokwakha, lunokusetyenziswa njenge-arhente yokugcina amanzi kunye ne-retarder kudaka lwesamente ukwenza udaka olumpompekayo.

Ezi zilandelayo zezinye iimpawu ze-hydroxypropyl methylcellulose:

1. Ngokuzinza kwayo kakuhle, i-emulsions kunye ne-resin e-soluble resin coatings ingasetyenziselwa njenge-emulsifiers, i-stabilizers kunye ne-thickeners, njl., ukwenzela ukuba i-coating igugile kwaye ibambelele, kwaye ivumele ixabiso le-PH elizinzile.

2. Inokugcinwa kwamanzi. Umsebenzi oyintloko we-hydroxypropyl methylcellulose putty powder kukuba ndiyakwazi ukugcina amanzi kwaye ndidlale indima ye-lubrication kunye nokubambelela. Iphucula ukuxhathisa i-shrink and self-skin ukukhusela i-powdering phenomenon.

3. Ine-dispersibility enhle kwii-synthetic resins. Njenge-agent ekhuselayo, i-hydroxypropyl methylcellulose inokudlala indima ebalulekileyo ekukhuseleni ukuhlanganiswa kweengqungquthela ze-polymer kunye nokuphucula ukuzinza kwe-resin particle dispersion.

Ukongeza kwezi zakhiwo, i-hydroxypropyl methylcellulose, kunye nokuqina kakuhle, ukunamathela okuqinileyo, ukwakhiwa kunye nezinye iimpawu, kunokubonwa ukuba ukusebenza kwayo kuhle kakhulu. Ngenxa yale misebenzi, i-hydroxypropyl methylcellulose isetyenziswa ngokubanzi kumashishini amaninzi, afana neshishini lokwakha, ishishini lokugquma, njl., kunye ne-hydroxypropyl methylcellulose iyimfuneko.
