Pena HEC

ʻO ka pena HEC Hydroxyethyl cellulose he ʻano polymer non-ionic water-soluble, keʻokeʻo a melemele paha ka pauka, maʻalahi ke kahe, ʻaʻala a ʻono ʻole, hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a me ka wai wela, a piʻi ka dissolution rate me ka mahana, maʻamau insoluble i loko. ka nui o nā mea hoʻoheheʻe organik.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 mālamalama, 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

ʻO ka 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 ka paʻa 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.

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 ka 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 ʻāpana o ka mea hoʻoheheʻe organik a i ʻole ka wai hau me kahi ʻāpana o ka hydroxyethyl cellulose.Ma hope o 5-30 mau minuke, hydrolyzes ka papa pena HEC a piʻi aʻe.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 HEC kiʻekiʻe pena, pono e hoʻoulu 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 nā mea nui a i ʻole pololei i loko o ka nui a i ʻole spherical Paint grade HEC.

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 Paint grade HEC hydroxyethyl cellulose, no laila, pono e uku nui ia.

Mai hoʻohui i kekahi mea maʻamau i ka hui ʻana ma mua o ka hoʻopiha ʻia ʻana o ka pauka HEC hydroxyethyl cellulose 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 helu HEC kiʻekiʻe viscosity, ʻaʻole pono ke kiʻekiʻe o ka waiʻona makuahine ma mua o 2.5-3% (ma ke kaupaona), 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 mea mānoanoa kūlohelohe ʻē aʻe i loko o ke ʻano pena a me ka ratio hoʻohālikelike me ka pena HEC.)

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.
