Pehea e hoʻohana ai i ka Hydroxyethyl cellulose i ka pena latex?

Hydroxyethyl cellulosehoʻohana nui ʻia i ka pena latex, pena emulsion a me nā uhi, pehea e hoʻohana ai i ka Hydroxyethyl cellulose i ka pena latex?

1. Hoʻohui pololei i ka pigment abrasive

ʻO kēia ala ka mea maʻalahi loa a he manawa pōkole.ʻO nā ʻanuʻu kikoʻī penei:

(1) E hoʻohui i ka wai hoʻomaʻemaʻe kūpono i ka pahu o ka mea hoʻoulu kiʻekiʻe (ma ka laulā, hoʻohui ʻia ka ethylene glycol, ka mea hoʻomaʻemaʻe a me ka mea hana kiʻiʻoniʻoni i kēia manawa)

(2) E hoʻomaka i ka hoʻoulu ʻana me ka wikiwiki haʻahaʻa a hoʻohui mālie i ka hydroxyethyl cellulose

(3) hoʻomau i ka hoʻoulu ʻana a pulu nā ʻāpana āpau

(4) Hoʻohui i ka mea hoʻopaʻapaʻa mildew, pH adjuster, etc.

(5)E hoʻoulu a hiki i ka hydroxyethyl celluloseua hoʻoheheʻe ʻia (ua hoʻonui nui ʻia ka viscosity o ka hopena) ma mua o ka hoʻohui ʻana i nā mea ʻē aʻe i ka hoʻokumu ʻana a me ka wili ʻana a hiki i ka hana ʻana o ka lacquer.

2. lako me ka rama makuahine

Ua hoʻolako mua ʻia kēia ʻano me ka ʻoi aku ka nui o ka waiʻona makuahine a laila hoʻohui ʻia i ka pena latex.ʻO ka pōmaikaʻi o kēia ʻano hana ʻoi aku ka maʻalahi a hiki ke hoʻohui pololei ʻia i ka pena i hoʻopau ʻia, akā pono e mālama pono ʻia.Ua like nā ʻanuʻu a me nā ʻano hana me nā ʻanuʻu (1)-(4) ma ke ʻano 1, koe naʻe ʻaʻole pono ke kiʻekiʻe o ka mea hoʻonāuki, a ʻo kahi mea hoʻouluulu wale nō i lawa ka mana e hoʻopuehu like i nā fibers hydroxyethyl i loko o ka hopena. .hiki.E hoʻomau i ka hoʻoulu ʻana a hiki i ka hoʻoheheʻe ʻia ʻana i loko o kahi solution viscous.Pono e hoʻomaopopo ʻia e hoʻohui koke ʻia ka mea hoʻopololei i ka waiʻona makuahine.

3. me ka porridge

No ka mea, ʻo ka mea hoʻoheheʻe organik he mea hoʻoheheʻe maikaʻi ʻole no ka hydroxyethyl cellulose, hiki ke hoʻohana ʻia kēia mau mea hoʻoheheʻe organik e hāʻawi i kahi porridge.ʻO nā mea hoʻoheheʻe kūlohelohe i hoʻohana pinepine ʻia e like me ka ethylene glycol, propylene glycol, a me nā mea hana kiʻiʻoniʻoni (e like me ka hexane a i ʻole diethylene glycol butyl acetate), ʻo ka wai hau he mea hoʻoheheʻe maikaʻi ʻole, no laila hoʻohana pinepine ʻia ka wai hau me nā wai kūlohelohe. porridge.Hiki ke hoʻohui pololei ʻia ka hydroxyethyl cellulose e like me ka porridge i ka pena.Ua lawa ka hoʻomoʻu ʻia ʻana o ka hydroxyethyl cellulose i loko o ka pā.Ke hoʻohui ʻia i ka pena, hoʻoheheʻe koke ia a mānoanoa.Ma hope o ka hoʻohui ʻana, pono e hoʻomau mau a hiki i ka pau ʻana o ka hydroxyethyl cellulose a homogeneous.ʻO ka maʻamau, ua hui pū ʻia ka porridge me kahi ʻāpana o ka solvent organik a i ʻole ka wai hau a me kahi hapa o ka hydroxyethyl cellulose.Ma hope o 5 a 30 mau minuke, hydrolyzed ka hydroxyethyl cellulose a piʻi maikaʻi loa.Ma keʻano laulā, kiʻekiʻe loa ka haʻahaʻa o ka wai i ke kauwela a ʻaʻole pono e hoʻohana ʻia no ka porridge.

4. E mālama i ka hoʻohana ʻana i ka waiʻona makuahine hydroxyethyl cellulose

Mai ka hydroxyethyl cellulose (HEC)he granule i mālama ʻia, maʻalahi ke mālama a hoʻoheheʻe ʻia i loko o ka wai ke ʻike ʻia kēia mau mea.

(1) Ma mua a ma hope o ka hoʻohui ʻia ʻana o ka hydroxyethylcellulose, pono e hoʻomau ʻia ka hoʻoulu ʻana a hiki i ka maʻemaʻe o ka hopena.

(2) Pono e kānana mālie ʻia i loko o ka pahu hui.Mai hoʻohui i ka hydroxyethyl cellulose i hana ʻia i loko o ka poloka a me ke ʻano spherical pololei i loko o ka pahu hui.

(3) He pilina koʻikoʻi ka mahana o ka wai a me ka waiwai pH i ka wai me ka hemo ʻana o ka hydroxyethyl cellulose, a pono e mālama pono.

(4) Mai hoʻohui i kekahi mau mea alkaline i ka hui ʻana ma mua o ka pulu ʻana o ka pauka hydroxyethyl cellulose e ka wai.ʻO ka hoʻonui ʻana i ka pH ma hope o ka wai ʻana e kōkua i ka hoʻoheheʻe.

(5) E hoʻohui i nā mea hoʻopaneʻe mold i ka hikiwawe.

(6) I ka hoʻohana ʻana i ka hydroxyethyl cellulose viscosity kiʻekiʻe, ʻaʻole pono ke kiʻekiʻe o ka inu wai makuahine ma mua o 2.5-3% (ma ke kaupaona), inā ʻaʻole paʻakikī ka inu ʻana o ka makuahine.
