Pataki ti Hydroxypropyl MethylCellulose (HPMC) ninu PVC

A gba iyege ati win-win gẹgẹbi ilana iṣiṣẹ, ati tọju gbogbo iṣowo pẹlu iṣakoso ti o muna ati abojuto.

Awọn ọja Hydroxypropyl Methyl Cellulose ni agbara to pọ julọ ni agbegbe ti idadoro polymerization ti fainali kiloraidi ni Ilu China. Ni idadoro polymerization ti fainali kiloraidi, awọn tuka eto ni o ni kan taara ikolu lori ọja, PVC resini, ati lori awọn didara ti awọn oniwe-processing ati awọn ọja. HydroxypropylMethylCellulose ṣe iranlọwọ lati mu iduroṣinṣin gbona ti resini dara ati ṣakoso pinpin iwọn patiku.Resini PVC ti a ṣe lati didara giga HydroxypropylMethylCellulose kii ṣe nikan le rii daju laini iṣẹ pẹlu awọn iṣedede kariaye, ṣugbọn tun le ni awọn ohun-ini ti o han gbangba ti ara, awọn ohun-ini patiku ti o dara julọ ati ihuwasi rheological yo dara julọ.

 

Ninu iṣelọpọ ti awọn resini sintetiki, gẹgẹbi polyvinyl kiloraidi, polyvinylidene kiloraidi, ati awọn copolymers miiran, polymerization idadoro jẹ eyiti a lo julọ ati pe o gbọdọ jẹ awọn monomers hydrophobic alayipada ti daduro ninu omi. Gẹgẹbi awọn polima olomi-tiotuka, ọja HydroxypropylMethylCellulose ni iṣẹ dada ti o dara julọ ati awọn iṣẹ bi awọn aṣoju colloidal aabo.
