Hoʻohana ʻia ka Hydroxypropyl Methyl Cellulose (HPMC) no ka pena wai

ʻO kā mākou cellulose ether wai paʻa hana no ka latex coating, ʻoi aku ka kiʻekiʻe o ka PVA coating e hāʻawi i ka hana hoʻopiʻi maikaʻi loa, ka uhi ʻana no ka pulp mānoanoa, ʻaʻole e hoʻopuka i ka flocculation; Hiki i kona hopena mānoanoa kiʻekiʻe ke hōʻemi i ka dosage, hoʻomaikaʻi i ka hoʻokele waiwai o ka hoʻokumu ʻana, a hoʻomaikaʻi i ka hoʻokuʻu ʻana o ka ʻōnaehana uhi. ʻOi aku ka maikaʻi o nā waiwai rheological i ka uhi ʻana, hiki ke noho i kahi kūlana paʻa, mālama i ke kūlana mānoanoa maikaʻi loa o ka uhi; Ma ka moku i hoʻolei ʻia, me ka wai maikaʻi loa, ʻaʻole e paʻi; I loko o ka uhi a me ka wili wili, maʻalahi ka hoʻolaha ʻana i ka substrate, hana maʻalahi; Ke hoʻopau ʻia ka uhi ʻana, e hoʻihoʻi koke ka viscosity o ka ʻōnaehana, e hoʻopuka koke ke kahe.

I loko o ka honua ikaika loa o nā pena latex e pili ana i ka wai, hoʻokahi mea hoʻohui koʻikoʻi ʻo Hydroxy Propyl Methyl Cellulose.(HPMC). Ma waho aʻe o ka mānoanoa maikaʻi loa, hāʻawi kēia ʻano mea hoʻohui i nā ʻano waiwai ʻē aʻe, e like me ka brush-ability, sag resistance, emulsification, suspension power, etc.kekahihana i kēia ʻano mānoanoa i mea kaulana loa me nā mea hana pena i ka honua.

Hoʻohana ʻia i ka pena wai. Hōʻike ia i kona hopena mānoanoa kiʻekiʻe,anā waiwai rheological, ka hoʻopuehu a me ka solubility. Loaʻa iā ia ka bio-stability maikaʻi, hāʻawi i ka manawa kūpono no ka hale kūʻai pena. E pale pono i nā puaʻa a me ka hoʻopiha piha.
