Pena HEC

Papa penaʻO HEC Hydroxyethyl cellulose kahi ʻano o ka polymer non-ionic water-soluble, keʻokeʻo a melemele paha, maʻalahi ke kahe, ʻala a ʻono ʻole, hiki ke hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, a piʻi ka dissolution rate me ka mahana, maʻamau insoluble i ka hapa nui nā mea hoʻoheheʻe. Loaʻa iā ia ka paʻa PH maikaʻi a me ka loli viscosity liʻiliʻi i ka laulā o ph2-12. He kiʻekiʻe ka paʻakai paʻakai a me ka hiki hygroscopic HEC, a he ikaika ka paʻa wai hydrophilic. Loaʻa i kāna ʻano wai ka hana ʻili a me nā huahana viscosity kiʻekiʻe he pseudoplasticity kiʻekiʻe. Hiki ke hana ʻia i kiʻi ʻoniʻoni aniani anhydrous me ka ikaika haʻahaʻa, ʻaʻole maʻalahi i ka ʻaila, ʻaʻole i pā ʻia e ka māmā, aia nō he kiʻi ʻoniʻoni wai-soluble HEC. Ma hope o ka hoʻomaʻamaʻa ʻana i ka ʻili, hoʻopuehu ʻo HEC a ʻaʻole hui i ka wai, akā hoʻoheheʻe mālie. Hiki ke hoʻololi i ka PH i 8-10 a hemo koke.

ʻO nā waiwai nui

Hydroxyethyl cellulose(HEC)hiki ke hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, a ʻaʻohe ʻano gel. Loaʻa iā ia kahi ākea o ka hoʻololi, solubility a me ka viscosity. Loaʻa iā ia ke kūpaʻa wela maikaʻi (ma lalo o 140 ° C) a ʻaʻole hana ma lalo o nā kūlana acidic. ka ua. Hiki i ka solution hydroxyethyl cellulose (HEC) ke hana i kahi kiʻiʻoniʻoni akaka, nona nā hiʻohiʻona non-ionic ʻaʻole e launa pū me nā ion a loaʻa ka launa maikaʻi.

Ma ke ʻano he colloid pale, hiki ke hoʻohana ʻia ka Paint grade HEC no ka vinyl acetate emulsion polymerization e hoʻomaikaʻi i ka paʻa o ka ʻōnaehana polymerization ma kahi ākea PH. I ka hana ʻana i nā huahana i hoʻopau ʻia e hana i ka puaʻa, filler a me nā mea hoʻohui ʻē aʻe i hoʻopuehu ʻia, kūpaʻa a hāʻawi i ka hopena mānoanoa. Hiki ke hoʻohana ʻia no ka styrene, acrylic, acrylic a me nā polymers i hoʻokuʻu ʻia e like me nā dispersants, hoʻohana ʻia i ka pena latex hiki ke hoʻomaikaʻi nui i ka mānoanoa, hoʻomaikaʻi i ka hana pae.

Nā huahana Papa helu 

ʻO ke ala hoʻohana o ka hydroxyethyl cellulose HEC i ka waipena

1. Hoʻohui pololei i ka wā e wili ai i ka puaʻa: ʻo kēia ʻano ka maʻalahi, a pōkole ka manawa i hoʻohana ʻia. ʻO nā ʻanuʻu kikoʻī penei:

(1) E hoʻohui i ka wai hoʻomaʻemaʻe kūpono i loko o ka VAT o ka mea hoʻokiʻekiʻe kiʻekiʻe (ʻo ka maʻamau, 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) E hoʻomau i ka hoʻoulu ʻana a hiki i ka pau ʻana o nā ʻāpana āpau

(4) hoʻohui i ka mildew inhibitor, PH regulator, etc

(5) E hoʻoulu a hiki i ka pau ʻana o ka hydroxyethyl cellulose (ua hoʻonui nui ʻia ka viscosity o ka hopena) ma mua o ka hoʻohui ʻana i nā mea ʻē aʻe i loko o ke kumu, a wili a lilo i pena.

2. lako me ka wai makuahine e kali ana: ua hoʻolako mua ʻia kēia ʻano hana me kahi kiʻekiʻe o ka wai makuahine, a laila hoʻohui i ka pena latex, ʻoi aku ka maikaʻi o kēia ʻano hana, hiki ke hoʻohui pololei ʻia i ka pena i nā huahana i hoʻopau ʻia, akā pono e mālama pono. . Ua like nā ʻanuʻu a me nā ʻano hana me nā ʻanuʻu (1) - (4) ma ke ʻano 1, koe wale nō ʻaʻole koi ʻia kahi mea hoʻokiʻekiʻe kiʻekiʻe a ʻo kekahi mea hoʻouluulu wale nō me ka mana lawa e mālama pono ai i nā fibers hydroxyethyl i hoʻopuehu ʻia i loko o ka hopena ua lawa. E hoʻomau i ka hoʻoulu ʻana a hiki i ka hoʻoheheʻe ʻana i loko o kahi hopena manoanoa. E hoʻomaopopo pono e hoʻohui koke ʻia ka mea hoʻopuʻi maloʻo i ka waiʻona makuahine.

3. Porridge like phenology: No ka mea, he mau mea hoʻoheheʻe kino nā mea hoʻoheheʻe ʻino no ka hydroxyethyl cellulose, hiki ke hoʻolako ʻia kēia mau mea hoʻoheheʻe organik me ka porridge. ʻO nā mea hoʻoheheʻe organik i hoʻohana pinepine ʻia e like me ka ethylene glycol, propylene glycol, a me nā mea hana kiʻiʻoniʻoni (e like me hexadecanol a 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 i loko o ka porridge. ʻO Gruel - e like me ka hydroxyethyl cellulose hiki ke hoʻohui pololei i ka pena. Ua hoʻopiha ʻia ʻo Hydroxyethyl cellulose i loko o ke ʻano porridge. Ma hope o ka hoʻohui ʻana i ka lacquer, e hoʻoheheʻe koke a loaʻa ka hopena mānoanoa. Ma hope o ka hoʻohui ʻana, e hoʻomau i ka hoʻoulu ʻana a hiki i ka hydroxyethyl cellulose e hoʻoheheʻe ʻia a ʻaʻahu. Hana ʻia kahi pākī maʻamau ma ka hui ʻana i ʻeono mau ʻāpana o ka solvent organik a i ʻole ka wai hau me kahi ʻāpana o ka hydroxyethyl cellulose. Ma hope o 5-30 mau minuke, ka papa penaHEChydrolyzes a ʻike ʻia ke ala. I ke kauwela, ua kiʻekiʻe ka haʻahaʻa o ka wai no ka hoʻohana ʻana i ka porridge.

4. Nā mea e pono ai ka nānā ʻana i ka hoʻolako ʻana i ka waiʻona makuahine hydroxyethyl cellulose:

Pka mālama ʻana

1 Ma mua a ma hope o ka hoʻohui ʻana i ka papa penaHEC, pono e hoʻoulu mau ʻia a hiki i ka ʻike a maopopo loa ka hopena.

2. E kānana mālie i ka hydroxyethyl cellulose i loko o ka pahu hui. Mai hoʻohui iā ia i loko o ka pahu hui i ka nui a i ʻole pololei i loko o ka nui a i ʻole spherical Paint gradeHEC.

3 ka wela o ka wai a me ka waiwai pH o ka wai i maopopo ka pili ana i ka hemo ana o ka papa penaHEChydroxyethyl cellulose, no laila pono ke nānā pono iā ia.

Mai hoʻohui i kekahi mea maʻamau i ka hui ʻana ma mua o ka papa penaHECʻO ka pauka hydroxyethyl cellulose e hoʻomoʻi ʻia me ka wai. ʻO ka hoʻonui ʻana i ka pH ma hope o ka wai ʻana e kōkua i ka hoʻoheheʻe.

5. E like me ka hiki, e hoʻohui mua i ka mildew inhibitor.

6 I ka hoʻohana ʻana i ka papa pena viscosity kiʻekiʻeHEC, ʻAʻole pono ke kiʻekiʻe o ka waiʻona makuahine ma mua o 2.5-3% (ma ke kaumaha), inā ʻaʻole paʻakikī ka hana ʻana i ka waiʻona makuahine.

Nā mea e pili ana i ka viscosity o ka pena latex

1. ʻOi aku ka nui o nā ea ea i loko o ka pena, ʻoi aku ka kiʻekiʻe o ka viscosity.

2. Ua kūlike ka nui o ka mea hoʻoulu a me ka wai i loko o ke ʻano pena?

3 i ka synthesis o ka latex, koena catalyst oxide maʻiʻo o ka nui.

4. ʻO ke ʻano o nā mānoanoa kūlohelohe ʻē aʻe i loko o ke ʻano pena a me ka ratio hoʻohālikelike me ka papa penaHEC.)

5. ma ke kaʻina hana pena, ua kūpono ke ʻano o nā ʻanuʻu e hoʻohui i ka mānoanoa.

6. Ma muli o ka hoʻonāukiuki nui a me ka haʻahaʻa nui i ka wā e hoʻopuehu ai.

7.Microbial erosion o thickener.
