No ka mea he haʻahaʻa loa ka viscosity o ka resin wai, ʻaʻole hiki ke hoʻokō i nā pono o ka mālama ʻana a me ke kūkulu ʻana i ka hana o ka uhi ʻana, no laila pono e hoʻohana i ka mānoanoa kūpono e hoʻoponopono i ka viscosity o ka uhi ʻana i ka wai i ke kūlana kūpono.

Nui nā ʻano ʻano mānoanoa.I ke koho ʻana i nā mānoanoa, i ka hoʻohui ʻana i kā lākou mānoanoa a me ka mālama ʻana i ka rheology uhi, pono e noʻonoʻo ʻia kekahi mau mea ʻē aʻe e hana i ka uhi ʻana i ka hana hana maikaʻi loa, ke ʻano kiʻi ʻoniʻoni maikaʻi loa a me ke ola lawelawe lōʻihi loa.

ʻO ke koho ʻana o nā ʻano mānoanoa e pili ana i ka pono a me ke kūlana maoli o ka hoʻokumu ʻana.

Ke koho a hoʻohana i nā mānoanoa, he mea nui kēia.

1. He ʻoi aku ka nui o ka hoʻopili ʻana o ka HEC me ka haʻahaʻa haʻahaʻa a hōʻike i ka ʻoi aku ka mānoanoa o ka mālama ʻana.A i ka wā e piʻi ai ka nui o ka shear rate, ua luku ʻia ke aupuni wili, ʻoi aku ka nui o ka shear rate, ʻoi aku ka liʻiliʻi o ka hopena o ke kaumaha mole ma ka viscosity.ʻAʻohe mea e pili ana i kēia mīkini mānoanoa me ka waihona kumu, nā puaʻa a me nā mea hoʻohui i hoʻohana ʻia, pono wale ke koho i ke kaumaha molekala kūpono o ka cellulose a hoʻoponopono i ka ʻike o ka thickener hiki ke loaʻa ka viscosity kūpono, a no laila hoʻohana nui ʻia.

2.HEUR mānoanoa mea he viscous aqueous solution me ka diol a me ka diol ether e like me co-solvent, me ka paa o 20% ~ 40%.ʻO ke kuleana o ka co-solvent ka mea e pale ai i ka hoʻopili ʻana, inā ʻaʻole ia mau mānoanoa i loko o ka mokuʻāina gel i ka ʻike like.I ka manawa like, hiki i ke alo o ka solvent ke pale i ka huahana mai ka hau, akā pono e hoʻomehana ʻia i ka hoʻoilo ma mua o ka hoʻohana ʻana.

3. He maʻalahi nā huahana paʻa haʻahaʻa, haʻahaʻa-viscosity e hoʻolei a hiki ke lawe ʻia a mālama ʻia i ka nui.No laila, loaʻa i kekahi mau mea mānoanoa HEUR ka ʻokoʻa paʻa o ka lako huahana like.ʻOi aku ka kiʻekiʻe o ka maʻiʻo co-solvent o nā mānoanoa viscosity haʻahaʻa, a ʻoi aku ka haʻahaʻa o ka viscosity mid-shear o ka pena ke hoʻohana ʻia, hiki ke hoʻopau ʻia ma ka hōʻemi ʻana i ka co-solvent i hoʻohui ʻia ma nā wahi ʻē aʻe o ka hoʻolālā.

4. Ma lalo o nā kūlana hui kūpono, hiki ke hoʻohui pololei ʻia ka HEUR haʻahaʻa haʻahaʻa i nā pena latex.Ke hoʻohana nei i nā huahana viscosity kiʻekiʻe, pono e hoʻoheheʻe ʻia ka mānoanoa me ka hui ʻana o ka wai a me ka co-solvent ma mua o ka hiki ke hoʻohui ʻia.Inā hoʻohui ʻoe i ka wai e hoʻoheheʻe pololei i ka mānoanoa, e hōʻemi ia i ka neʻe ʻana o ka co-solvent kumu i loko o ka huahana, e hoʻonui ai i ka adhesion a hoʻonui i ka viscosity.

5. ʻO ka hoʻohui ʻana i ka mea mānoanoa i ka pahu hui e pono ke kūpaʻa a me ka lohi, a pono e hoʻokomo ʻia ma ka pā pā.ʻAʻole pono e wikiwiki ka wikiwiki o ka hoʻohui ʻana i ka paʻa ʻana o ka mānoanoa ma luna o ka ʻili o ka wai, akā pono e huki ʻia i loko o ka wai a wili ʻia i lalo a puni ke kumu hoʻoulu, i ʻole e hui maikaʻi ka mānoanoa a i ʻole e mānoanoa loa ka mānoanoa. a i ʻole flocculated ma muli o ke kiʻekiʻe o ka pae kūloko.

6. Hoʻohui ʻia ka mānoanoa HEUR i ka pahu hui pena ma hope o nā mea wai ʻē aʻe a ma mua o ka emulsion, i mea e hōʻoia ai i ka ʻoi loa o ka nani.

7. Hoʻohui pololei ʻia nā mea mānoanoa HASE i ka pena ma ke ʻano he emulsion i ka hana ʻana i nā pena emulsion me ka ʻole o ka dilution a i ʻole pre-neutralization.Hiki ke hoʻohui ʻia ma ke ʻano he ʻāpana hope loa i ka hui hui ʻana, i ka māhele dispersion puaʻa, a i ʻole ka mea mua i ka hui ʻana.

8. No ka mea, he emulsion waikawa kiʻekiʻe ka HASE, ma hope o ka hoʻohui ʻana, inā he alkali i loko o ka pena emulsion, e hoʻokūkū ʻo ia no kēia alkali.No laila, ua koi 'ia e hoʻohui i ka HASE thickener emulsion mālie a me ka steadily, a hoʻoulu maikaʻi, i ole, e hana i ka puaʻa dispersion nenoaiu a emulsion binder kūloko instability, a me ka hope ua stabilized e ka neutralized ili hui.

9. Hiki ke hoʻohui ʻia ka alkali ma mua a ma hope paha o ka hoʻohui ʻia ʻana o ka mea mānoanoa.ʻO ka pōmaikaʻi o ka hoʻohui ʻana ma mua, ʻo ia ka hōʻoia ʻana ʻaʻole hiki ke hoʻokō ʻia ka hoʻopuehu ʻana o ka puaʻa a i ʻole ka emulsion binder e ka mānoanoa e hopu ana i ka alkali mai ka ʻili o ka puaʻa a i ʻole ka mea hoʻopili.ʻO ka maikaʻi o ka hoʻohui ʻana i ka alkali ma hope o ka hoʻopuehu maikaʻi ʻana o nā ʻāpana mānoanoa ma mua o ka pehu ʻana a hoʻoheheʻe ʻia paha e ka alkali, e pale ana i ka mānoanoa kūloko a i ʻole agglomeration, e pili ana i ka hoʻokumu ʻana, nā mea hana a me nā kaʻina hana.ʻO ke ala palekana ʻo ka hoʻoheheʻe ʻana i ka mānoanoa HASE me ka wai ma mua a laila hoʻokaʻawale iā ia me ka alkali ma mua.

10. Hoʻomaka ka ʻōhū ʻana o ka mānoanoa HASE ma kahi pH ma kahi o 6, a hiki i ka hana mānoanoa ke pāʻani piha i ka pH o 7 a i 8. ʻO ka hoʻoponopono ʻana i ka pH o ka pena latex ma luna o 8 hiki ke mālama i ka pH o ka pena latex mai ka emi ʻana ma lalo o 8. , pēlā e hōʻoia ai i ka paʻa o ka viscosity.
