Focus on Cellulose ethers

Te Whakamahinga o te Matū Matū o ia ra Hydroxypropyl Methyl Cellulose (HPMC) i roto i te horoi matū ia ra

Ko te hydroxypropyl methylcellulose matū o ia ra he polymer waihanga i hangaia mai i te cellulose taiao ma te whakarereketanga matū. Ko te cellulose ether he hua o te cellulose taiao. He rereke te hanga o te cellulose ether i nga polymers waihanga. Ko te mea tino taketake ko te cellulose, he pūhui polymer māori.

Na te mea motuhake o te hanganga cellulose maori, karekau he kaha o te cellulose ki te tauhohe me nga apiha whakaea. Heoi, i muri i te maimoatanga o te kaipupuhi pupuhi, ka pakaru nga hononga hauwai kaha i waenga i nga mekameka ngota me nga mekameka, a, ko te tukunga kaha o te roopu hydroxyl ka waiho hei cellulose alkali. Whai muri i te tauhohenga o te kaihoko whakaetere, ka huri te roopu -OH ki te roopu RĀNEI Whiwhi i te cellulose ether. Ko te 200,000-viscosity hydroxypropyl methylcellulose mo te "Max" te karaehe matū o ia ra he paura ma, he paku kowhai ranei, he hongi, he reka, he kore-paitini. Ka taea te rewa i roto i te wai matao me te whakarewa whakauru o te mea waro hei hanga i tetahi otinga poikeri marama.

Ko te wai-whakamahi wai he mahi mata, he tino marama, he kaha te pumau, kaore e pa ki te pH ina rewa ki te wai. He whakamaaru me te whakatio i roto i nga shampoos me nga wai kaukau, he pupuri wai me nga taonga hanga kiriata pai mo te makawe me te kiri. Na te kaha o te pikinga o nga rawa taketake, ko te whakamahi i te cellulose (antifreeze thickener) i roto i te shampoo me te wai horoi ka taea te whakaiti i te utu me te whakatutuki i te painga e hiahiatia ana.
