Papa pena CMC

ʻO ka pena CMC Sodium carboxymethyl cellulose i hoʻololi ʻia me ka ether structure o cellulose derivatives, ʻelua mau mānoanoa, paʻa wai, hoʻopaʻa, hoʻopaʻa paʻa, emulsifying dispersion, pale colloid a me nā mea ʻē aʻe. ka viscosity a me ka rheology o nā uhi, no laila ua hoʻohana nuiʻia i nāʻanoʻokoʻa likeʻole, ka latex coatings, ka wai i waho a me ka loko o loko, ka hoʻoleiʻana i nā mea hoʻolei a pēlā aku.

Hiki ke hoʻohana ʻia ka papa pena CMC ma ke ʻano he anti-sinking agent, emulsifier, dispersant, leveling agent, adhesive, hiki ke hana i ka ʻāpana paʻa o ka uhi i hoʻokaʻawale ʻia i loko o ka solvent, i ʻole stratified ka uhi no ka manawa lōʻihi.

Nā hiʻohiʻona:

Hiki ke hoʻohana ʻia ka papa pena CMC ma ke ʻano he stabilizer no ka pale ʻana i ka wehe ʻana o ka pena ma muli o ka hoʻololi wikiwiki ʻana o ka mahana

Ma ke ʻano he viscosity agent, hiki i ka Paint grade CMC ke hana i ka pena ʻaʻahu mokuʻāina, hoʻokō i ka mālama maikaʻi a me ka viscosity kūkulu ʻana, a pale i ka delamination koʻikoʻi i ka wā mālama.

Hiki i ka pena CMC ke pale i ka kulu a me ke kau ʻana.

Loaʻa i ka ʻoluʻolu ʻo CMC ke ʻike maikaʻi a me nā ʻāpana gel liʻiliʻi.

1. Hoʻohana ʻia ʻo CMCma ka hoolei ana

ʻO ka CMC polymer pūhui, multistranded, ma hope o ka pehu ʻana o ka wai pololei-chain open a interactive form a mesh stretching, colloid, in sodium base bentonite a me kāna pilina, ʻaʻole hiki ke hoʻomaikaʻi wale i ka hiki o ka sodium base bentonite suspension, a hiki ke hoʻemi nui i ka nui agglomerate precipitation. , i ka manawa like e pale ai i ka pauka refractory, no laila ua hoʻohana pinepine ʻia e hoʻonui i ka helu o ka hoʻolei ʻana i ka uhi ʻana, I ka manawa like e hoʻomaikaʻi i ka viscosity pena:

* ʻOi loa ka wai solubility a me ka viscosity, hoʻomaikaʻi maikaʻi i ka viscosity uhi a me ka rheology

* Maikaʻi ka solubility a me ka hoʻopuehu, no laila ua hoʻokuʻu ʻia ka mea paʻa i loko o ka wai lawe

* Hoʻolaha i ka hoʻokuʻu ʻia ʻana o ka pauka refractory e pale i ka ua, stratification a me ka infiltration nui o ka mea lawe wai i loko o nā mea hana.

* E hoʻomaikaʻi i ka uhi ʻana a me ka hiki ke uhi ʻia o ka uhi, hoʻomaikaʻi i ka palaki a me ka pae ʻana o ka uhi

* Hoʻopili ʻia ka pauka i loko o ka uhi i kekahi i kekahi ma hope o ka maloʻo ʻana, a paʻa paʻa i ka ʻili o ke ʻano a me ke kumu.

 

2. Hoʻohana ʻia ʻo CMCpena maʻamau

CMC me ka hydroxyl macromolecular kaulahao hydration me ka wai, oiai wili, pela e hoonui ai i ka viscosity o ka wai mahele, i loko o ka wai a me ka organic solvents i maikai compatibility, a me ka compatibility o ka puaʻa mea maikaʻi, a hiki nui hoʻomaikaʻi i ka viscosity a me ka rheology o pena, ma ʻO ka ʻoihana pena i hoʻohana pinepine ʻia ma ke ʻano he mānoanoa, dispersant a me stabilizer, ʻO nā hopena kikoʻī o CMC i ka hoʻohana ʻana i ka wai-soluble coatings penei:

* ʻO ke kūpaʻa wai maikaʻi a me ka lōʻihi o ka uhi kiʻiʻoniʻoni

* ʻO ka piha kiʻiʻoniʻoni kiʻekiʻe, kiʻiʻoniʻoni like ʻole, hiki ke loaʻa i nā mea koʻikoʻi

* Ma ke ʻano he stabilizer, pale i ka wehe ʻana o ka uhi ma muli o ka hoʻololi wikiwiki ʻana o ka mahana;

* Ma ke ʻano he colloid pale, hiki ke mālama i ka paʻa o nā ʻōnaehana pale i kahi ākea o nā waiwai pH

* Hiki i ka mānoanoa ke hana i ka lole uhi, hoʻokō i ka mālama maikaʻi a me ka viscosity kūkulu, pale i ka stratification koʻikoʻi i ka wā mālama.

* E hoʻomaikaʻi i ka pae ʻana o ka uhi ʻana, hoʻomaikaʻi i ka pale ʻana i ka splash coating, ke kahe ʻana o ke kahe, i mea e hoʻomaikaʻi ai i ka hana hana o ka uhi.

* Hiki ke hana i ka puaʻa, mea hoʻopiha a me nā mea hoʻohui ʻē aʻe i hoʻopuehu like ʻia i loko o ka uhi ʻana, i loaʻa i ka uhi ka hopena hoʻopili kala maikaʻi.

 

3. Hoʻohana ʻia ʻo CMC i ka latexpena

ʻO ka polymer latex coating ka mea nui i haku ʻia me ka wai wai a pena i kekahi mele, ʻo kona viscosity pena i ka waiwai subsidence, besmear i ka pulupulu, roller a me ka piha o ka membrane, a me ka waiwai kahe i loko o ka membrane ma luna o ka ʻili o kahi hopena kahe kū pololei ua kau ʻia. no laila pono pinepine i ka viscosity a me ka waiwai rheological o ka latex coatings hiki ke hoʻololi, a CMC maikaʻi liquidity, i ka latex pena pulupulu kū'ēʻuʻuku, He mea maʻalahi ke kūkulu a hoʻohana 'ia e like me stabilizer, thickener a me ka wai paʻa 'ana no ka latex coatings:

* ʻO ka hopena mānoanoa maikaʻi loa, ka hana kiʻekiʻe o ka mānoanoa o ka latex coating

* Hiki ke hana i ka uhi me kekahi viscosity, i loko o ka waihona e ole precipitate, a me ka paʻa

* Hiki ke pale i ka wai mai ke komo wikiwiki ʻana i ka substrate porous, i hiki i ka ʻike kiʻekiʻe o ka emulsion ke hoʻokō i nā koi o ka paʻa ʻana o ka wai.

* Hoʻemi liʻiliʻi i ke ʻano o ka uhi ʻana, liʻiliʻi i ke ʻano o ka latex, dispersants a me nā surfactants

* Ke hoʻopau ʻia ka uhi ʻana, hoʻopau ʻia ka pōʻino o ka synthesis wai ma waena o CMC a me ka wai, a hoʻihoʻi ʻia ka viscosity e pale i ke kahe ʻana.

 

Hoʻopili ʻia:

Hoʻopili ʻia ka huahana CMC kiʻekiʻe kiʻekiʻe i ʻekolu ʻeke pepa me ka ʻeke polyethylene i loko i hoʻoikaika ʻia, ʻo ke kaumaha o ka ʻupena he 25kg no kēlā me kēia ʻeke.
