HEC no Pena

He pōkole ka HEC no ka hydroxyethyl Cellulose. Hydroxyethyl celluloseHEChe melemele keʻokeʻo a ʻeleʻele paha, ʻono ʻole, ʻona ʻole, fibrous a pauda paha i hoʻomākaukau ʻia e ka etherification o ka cellulose alkaline a me ka ethylene oxide (a i ʻole chloroethanol). He mea hoʻoheheʻe cellulose ether non-ionic. Ma ke ʻano he surfactant non-ionic, ma waho aʻe o ka mānoanoa, ka hoʻokuʻu ʻana, ka hoʻopaʻa ʻana, ka lana ʻana, ka hana kiʻiʻoniʻoni, dispersing, ka paʻa ʻana o ka wai a me ka pale.

Kemika hiʻona:

1, hiki ke hoʻoheheʻe ʻia ka HEC i ka wai wela a i ʻole ka wai anuanu, ʻaʻole e hoʻoheheʻe ʻia ka mahana kiʻekiʻe a i ʻole ka paila ʻana, i loaʻa iā ia ka nui o ka solubility a me nā waiwai viscosity, a me ka gel non-thermal;

2, hiki i kona non-ionic ke noho pū me ka nui o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, surfactants, paʻakai, he mea momona colloidal maikaʻi loa i loaʻa ka kiʻekiʻe o ka hopena electrolyte;

3, ʻoi aku ka nui o ka paʻa ʻana o ka wai ma mua o ka methyl cellulose, me ka hiki ke hoʻololi maikaʻi.

4. Aia ka HEC i ka mea hiki ke hoʻopuehu ʻino loa i ka methyl cellulose a me ka hydroxypropyl methyl cellulose, akā ʻoi aku ka ikaika o ka pale colloid.

No laila, hoʻohana nui ʻia ka hydroxyethyl cellulose i ka hoʻohana ʻana i ka aila, ka uhi ʻana, ke kūkulu ʻana, ka lāʻau lapaʻau a me ka meaʻai, ka textile, ka hana pepa a me ka polymer polymerization reaction a me nā māla ʻē aʻe.

Nā waiwai nui oHECno ka pena latex

1.Waiwai mānoanoa

ʻO ka Hydroxyethyl cellulose (HEC) kahi mānoanoa kūpono no nā uhi a me nā mea hoʻonaninani. I ka hoʻohana pono ʻana, ʻo ka hui pū ʻana o kona mānoanoa me ka hoʻokuʻu ʻana, ka palekana, ka hoʻopuehu a me ka mālama ʻana i ka wai e hoʻopuka i nā hopena kūpono.

1. pseudoplastic

ʻO ka Pseudoplasticity ka waiwai e emi ai ka viscosity o ka hopena me ka piʻi ʻana o ka wikiwiki rotational. He mea maʻalahi ka hoʻopili ʻana o ka HEC me ka palaki a i ʻole ka wili a hiki ke hoʻonui i ka maʻalahi o ka ʻili, hiki ke hoʻonui i ka pono hana; ʻO nā shampoos i loaʻa i ka Hec he wai a paʻa, maʻalahi e hoʻoheheʻe ʻia a maʻalahi hoʻi e hoʻopuehu.

1. Kūʻē paʻakai

Paʻa ʻo HEC i nā hāʻina paʻakai koʻikoʻi loa a ʻaʻole e decompose i loko o nā mokuʻāina ionic. Hoʻohana ʻia i ka electroplating, hiki ke hoʻopiha piha i ka papa plating, ʻoi aku ka mālamalama. ʻOi aku ka maikaʻi o ka hoʻohana ʻana i ka pena borate, silicate a me ka carbonate latex, ʻoi aku ka maikaʻi o ka viscosity.

4.He membranous

Hiki ke hoʻohana ʻia nā waiwai hana membrane o HEC i nā ʻoihana he nui. I nā hana hana pepa, i uhi ʻia me HEC glazing agent, hiki ke pale i ke komo ʻana o ka momona, a hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā ʻano ʻē aʻe o ka hoʻonā pepa; Hoʻonui ka HEC i ka elasticity o nā fibers i ka wā o ka ulana ʻana a no laila e hōʻemi i ka pōʻino mechanical iā lākou. Hana ʻo HEC ma ke ʻano he kiʻiʻoniʻoni pale manawaleʻa i ka wā o ka nui a me ke kala ʻana i ka lole a hiki ke holoi ʻia mai ka lole me ka wai inā ʻaʻole pono ka pale.

1. Paʻa wai

Kōkua ʻo HEC e mālama i ka makū o ka ʻōnaehana i kahi kūlana kūpono. No ka mea, hiki i ka liʻiliʻi o HEC i loko o ka hoʻonā wai ke hoʻokō i kahi hopena maikaʻi o ka mālama ʻana i ka wai, no laila e hoʻemi ka ʻōnaehana i ka koi no ka wai i ka hoʻomākaukau. Me ka ʻole o ka paʻa ʻana o ka wai a me ka hoʻopili ʻana, e hōʻemi ka mortar sima i kona ikaika a me ka hoʻopili ʻana, a ʻo ka pālolo hoʻi e hōʻemi i ka plasticity ma lalo o kekahi kaomi.

ʻO ke ala hoʻohana o ka hydroxyethyl cellulose HECi ka pena latex

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 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, hydrolyzes ka hydroxyethyl cellulose 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

No ka mea ʻo ka hydroxyethyl cellulose kahi pauka granular i mālama ʻia, maʻalahi ke mālama a hoʻoheheʻe ʻia i loko o ka wai me ka mālama ʻana.

Hoolaha

4.1 Ma mua a ma hope o ka hoʻohui ʻana i ka hydroxyethyl cellulose, pono e hoʻouluulu mau ʻia a hiki i ka ʻike ʻana o ka hopena.

4.2. E kānana mālie i ka hydroxyethyl cellulose i loko o ka pahu hui. Mai hoʻohui i loko o ka pahu hui i ka nui a i ʻole pololei i loko o ka hydroxyethyl cellulose nui a spherical paha.

4.ʻO 3 ka mahana o ka wai a me ka waiwai pH o ka wai e pili ana i ka hoʻoheheʻe ʻana o ka hydroxyethyl cellulose, no laila pono e nānā pono iā ia.

4.4Mai hoʻohui i kekahi mea maʻamau i ka hui ʻana ma mua o ka hoʻopiha ʻia ʻana o ka pauka hydroxyethyl cellulose me ka wai. ʻO ka hoʻonui ʻana i ka pH ma hope o ka wai ʻana e kōkua i ka hoʻoheheʻe.

4.5 E like me ka hiki, e hoʻohui mua i ka mea hoʻopuʻi maloʻo.

4.6 I ka hoʻohana ʻana i ka hydroxyethyl cellulose viscosity kiʻekiʻe, 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 mānoanoa kūlohelohe ʻē aʻe i loko o ke ʻano pena a me ka ratio o ka dosage meHEChydroxyethyl cellulose.)

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

6 Ma muli o ka haʻalulu nui a me ka haʻahaʻa haʻahaʻa i ka wā hoʻopuehu.

7 ʻAiʻi microbial o ka mānoanoa.
