Aia ka HEC i ka mānoanoa a me ka hoʻomaikaʻi ʻana i ka ikaika tensile o nā uhi i nā pena latex.
ʻO HEC (Hydroxyethyl cellulose) he polymer hiki ke hoʻololi i ka wai me ka hoʻoponopono viscosity maikaʻi, hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik, a hiki ke hana i nā emulsion paʻa i ka wai.Loaʻa iā ia ke kūpaʻa halogen maikaʻi, ka wela a me ke kūpaʻa alkali, a me ke kūpaʻa kemika kiʻekiʻe.Hoʻohana ʻia ʻo HEC e hoʻomaikaʻi i ka viscosity o ka peʻa latex, hoʻopaʻa i nā waiwai o ke ʻano, pale i ka agglomeration o ka pena latex, hoʻomaikaʻi i ka adhesion, ikaika tensile, hiki ke maʻalahi a me ke kūpaʻa ʻana o ke kiʻi ʻoniʻoni, ʻo ia kahi mea ʻenehana o ka hoʻomohala ʻana. kiʻekiʻe kiʻekiʻe latex pena.
ʻO ka hana nui o HEC ka hoʻomaikaʻi ʻana i nā waiwai mechanical o ka uhi.Hiki ke hoʻohana ʻia ma ke ʻano he anti-sedimentation agent, preservative a anti-viscosity agent.Me ka ʻole o ka manaʻo HEC, hiki iā ia ke hoʻonui i ka viscoelasticity o ka uhi, hoʻonui i ka ikaika tensile a me ka maʻalahi o ka uhi, a hoʻopau i ka shrinkage a me nā māwae o ke kiʻiʻoniʻoni.
Hāʻawi ʻo Hydroxyethyl cellulose i nā waiwai uhi maikaʻi loa no nā uhi latex, ʻoi aku ka nui o nā uhi PVA kiʻekiʻe.Ke mānoanoa ka uhi ʻana, ʻaʻole e hiki mai ka flocculation.
ʻO ka hydroxyethyl cellulose ka hopena mānoanoa kiʻekiʻe.Hiki iā ia ke hōʻemi i ka dosage, hoʻomaikaʻi i ka hoʻokele waiwai o ke ʻano, a hoʻomaikaʻi i ka pale ʻana i ka scrubbing o ka uhi.
ʻO ka wai wai o ka hydroxyethyl cellulose he non-Newtonian, a ua kapa ʻia nā waiwai o ka hopena thixotropy.
Ma ke kūlana paʻa, hoʻomau ka mānoanoa o ka ʻōnaehana uhi a wehe ʻia ma hope o ka pau ʻana o ka huahana.
I ka moku i ninini ʻia, mālama ka ʻōnaehana i kahi degere haʻahaʻa o ka viscosity, e hana ana i ka huahana i ka wai maikaʻi loa, a ʻaʻole e pīpī.
I loko o ka pulupulu a me ka ʻōwili, maʻalahi ka hoʻolaha ʻana o ka huahana ma ka substrate.He kūpono no ke kūkulu ʻana.I ka manawa like, loaʻa iā ia ka pale splash maikaʻi.Ke hoʻopau ʻia ka uhi ʻana, hoʻihoʻi koke ʻia ka viscosity o ka ʻōnaehana, a hoʻopuka koke ka uhi i ke kahe kahe.
