He pararopi te hydroxypropyl methylcellulose?

He pararopi te HPMC?
Ko te Hydroxypropyl methylcellulose (hpmc) he etera whakauru kore-cationic o te methylcellulose. He polymer ahua-ira, kore-motuhake, viscoelastic, e whakamahia nuitia ana i roto i te orthopedics hei wai whakahinuhinu, ka whakamahia ranei i roto i te rongoa waha hei taapiri, hei kaihoko ranei, a he mea noa ki nga momo hua. Hei taapiri kai, ka taea te whakamahi hydroxypropyl methylcellulose hei demulsifier, emulsifier, ranunga me te whakakapi mo te pectin kararehe iti.

Ka taea te whakamahi i te HPMC hei emulsifier, thickener, adhesive, forming agent, acid and alkali resistant architecture coating, filler, demulsifier, thickener me etahi atu kaupapa matua. Ka whakamahia nuitia i roto i nga rauemi kapia, taputapu petrochemical, porcelain, ahumahi pepa, hua hiako, ahumahi rongoa, kai me nga hua tiaki kiri.

1. Hangahanga ahumahi hanga: hei humectant me te retarder mo te kumete whakauru, ko te moata ciment te mahi o te raima o raro. Whakamahia te slurry, te raima, te paura putty pakitara o roto, etahi atu taonga whakapaipai whare ranei hei whakapiri hei whakapai ake i te paninga me te whakanui ake i te wa mahi. Ka taea te whakamahi hei whakapiri mo nga taera papa, te mapere taiao, me te whakapaipai kirihou, ka taea hoki te whakamahi hei whakapiri. Ko te mahi maukati-wai o te polypropylene teitei (hpmc) ka kore e ngawari te pakaru o te slurry na te tere o te whakamaroketanga, me te whakapai ake i te kaha o te pupuhi.

2. Te hanga porcelain: te tikanga ka whakamahia hei here mo nga hua uku.

3. I roto i te mara o te paninga hoahoanga: hei emulsifier, thickener me thickener i roto i te mara o paninga hoahoanga, he pai te whakarewatanga i roto i te wai whakarewa ranei. Hei tango porcelain.

4. Whakapaipai: Kei te whakamahia hei emulsifier, hei whakakorikori me te pupuhi i roto i te ahumahi waituhi tuhi, a he pai te whakarewatanga i roto i te wai, i nga whakarewa ranei.

5. Kirihou: tuku pokepokea ai, ngohengohe, lubricating wai, etc.

6. Polyethylene (pvc): Hei whakakaha mo te hanga pvc, he mea whakarereke nui mo te hanga pvc ma te tikanga whakahiato maanu.

7. Ētahi atu: Kei te whakamahia whānuitia tenei hua ki nga hua hiako, te hanga pepa, nga hua hou me te tiaki huawhenua me nga kakano miro.

8. Biopharmaceuticals: rauemi mata mo te paninga hoahoanga; nga rauemi mata mo nga kiriata kirihou; nga rauemi polymer tere tere mo te whakarite puhoi i nga whakaritenga rongoa Hainamana tuku iho; nga mea whakapakeke; granules; kiriata; whakapiringa
