He aha te whakamahi a HPMC i taku putty pakitara?

Ko te HPMC (Hydroxypropyl Methylcellulose) he polymer wairewa-wai ka whakamahia hei taapiri ki te putty pakitara. Ka whakamahia hei whakapai ake i nga ahuatanga o te tinana me te matū o te putty, penei i te pupuri wai, te piri, me te kaha mahi. Ka awhina ano hoki ki te whakaiti i te pakaru me te whakaheke, me te whakapai ake i te mauroa me te whakaoti o te putty. Ko te HPMC he polymer i ahu mai i te cellulose i ahu mai i nga puna tipu, penei i te miro, te rakau, me etahi atu mea kei roto i te cellulose. He taonga kore-paitini, kore-riri, me te kore-allergenic e haumaru ana mo te whakamahi i te putty pakitara. Ka whakamahia ano te HPMC ki etahi atu mea hanga, penei i te peita, te raima, me te moata, hei whakapai ake i o raatau taonga. Ko te HPMC he taapiri whai hua mo te putty pakitara, na te mea ka awhina i te whakapai ake i te mahi me te mau tonu o te putty, me te awhina ki te whakaiti i te pakaru me te whakaheke. Ka awhina ano ki te whakapai ake i te piri o te putty ki te mata o te pakitara, me te awhina ki te whakapai ake i te mutunga o te putty. Ko te HPMC he taapiri whai hua me te pai ki te taiao mo te putty pakitara, na te mea i ahu mai i nga puna ka taea te whakahou, kaore he paitini me te kore e whakapataritari.
